  • Enabling DNS for IPv6 infrastructure

    After successful automatic distribution of IPv6 address information via DHCPv6 in your local network it might be time to start offering some more services. Usually, we would use host names in order to communicate with other machines instead of their bare IPv6 addresses. During the following paragraphs we are going to enable our own DNS name server with IPv6 address resolving. This is the third article in a series on IPv6 configuration: Configure IPv6 on your Linux system DHCPv6: Provide IPv6 information in your local network Enabling DNS for IPv6 infrastructure Accessing your web server via IPv6 Piece of advice: This is based on my findings on the internet while reading other people's helpful articles and going through a couple of man-pages on my local system. What's your name and your IPv6 address? $ sudo service bind9 status * bind9 is running If the service is not recognised, you have to install it first on your system. This is done very easy and quickly like so: $ sudo apt-get install bind9 Once again, there is no specialised package for IPv6. Just the regular application is good to go. But of course, it is necessary to enable IPv6 binding in the options. Let's fire up a text editor and modify the configuration file. $ sudo nano /etc/bind/named.conf.optionsacl iosnet {        127.0.0.1;        192.168.1.0/24;        ::1/128;        2001:db8:bad:a55::/64;};listen-on { iosnet; };listen-on-v6 { any; };allow-query { iosnet; };allow-transfer { iosnet; }; Most important directive is the listen-on-v6. This will enable your named to bind to your IPv6 addresses specified on your system. Easiest is to specify any as value, and named will bind to all available IPv6 addresses during start. More details and explanations are found in the man-pages of named.conf. Save the file and restart the named service. As usual, check your log files and correct your configuration in case of any logged error messages. Using the netstat command you can validate whether the service is running and to which IP and IPv6 addresses it is bound to, like so: $ sudo service bind9 restart $ sudo netstat -lnptu | grep "named\W*$"tcp        0      0 192.168.1.2:53        0.0.0.0:*               LISTEN      1734/named      tcp        0      0 127.0.0.1:53          0.0.0.0:*               LISTEN      1734/named      tcp6       0      0 :::53                 :::*                    LISTEN      1734/named      udp        0      0 192.168.1.2:53        0.0.0.0:*                           1734/named      udp        0      0 127.0.0.1:53          0.0.0.0:*                           1734/named      udp6       0      0 :::53                 :::*                                1734/named   Sweet! Okay, now it's about time to resolve host names and their assigned IPv6 addresses using our own DNS name server. $ host -t aaaa www.6bone.net 2001:db8:bad:a55::2Using domain server:Name: 2001:db8:bad:a55::2Address: 2001:db8:bad:a55::2#53Aliases: www.6bone.net is an alias for 6bone.net.6bone.net has IPv6 address 2001:5c0:1000:10::2 Alright, our newly configured BIND named is fully operational. Eventually, you might be more familiar with the dig command. Here is the same kind of IPv6 host name resolve but it will provide more details about that particular host as well as the domain in general. $ dig @2001:db8:bad:a55::2 www.6bone.net. AAAA More details on the Berkeley Internet Name Domain (bind) daemon and IPv6 are available in Chapter 22.1 of Peter Bieringer's HOWTO on IPv6. Setting up your own DNS zone Now, that we have an operational named in place, it's about time to implement and configure our own host names and IPv6 address resolving. The general approach is to create your own zone database below the bind folder and to add AAAA records for your hosts. In order to achieve this, we have to define the zone first in the configuration file named.conf.local. $ sudo nano /etc/bind/named.conf.local //// Do any local configuration here//zone "ios.mu" {        type master;        file "/etc/bind/zones/db.ios.mu";}; Here we specify the location of our zone database file. Next, we are going to create it and add our host names, our IP and our IPv6 addresses. $ sudo nano /etc/bind/zones/db.ios.mu $ORIGIN .$TTL 259200     ; 3 daysios.mu                  IN SOA  ios.mu. hostmaster.ios.mu. (                                2014031101 ; serial                                28800      ; refresh (8 hours)                                7200       ; retry (2 hours)                                604800     ; expire (1 week)                                86400      ; minimum (1 day)                                )                        NS      server.ios.mu.$ORIGIN ios.mu.server                  A       192.168.1.2server                  AAAA    2001:db8:bad:a55::2client1                 A       192.168.1.3client1                 AAAA    2001:db8:bad:a55::3client2                 A       192.168.1.4client2                 AAAA    2001:db8:bad:a55::4 With a couple of machines in place, it's time to reload that new configuration. Note: Each time you are going to change your zone databases you have to modify the serial information, too. Named loads the plain text zone definitions and converts them into an internal, indexed binary format to improve lookup performance. If you forget to change your serial then named will not use the new records from the text file but the indexed ones. Or you have to flush the index and force a reload of the zone. This can be done easily by either restarting the named: $ sudo service bind9 restart or by reloading the configuration file using the name server control utility - rndc: $ sudo rndc reconfig Check your log files for any error messages and whether the new zone database has been accepted. Next, we are going to resolve a host name trying to get its IPv6 address like so: $ host -t aaaa server.ios.mu. 2001:db8:bad:a55::2Using domain server:Name: 2001:db8:bad:a55::2Address: 2001:db8:bad:a55::2#53Aliases: server.ios.mu has IPv6 address 2001:db8:bad:a55::2 Looks good. Alternatively, you could have just ping'd the system as well using the ping6 command instead of the regular ping: $ ping6 serverPING server(2001:db8:bad:a55::2) 56 data bytes64 bytes from 2001:db8:bad:a55::2: icmp_seq=1 ttl=64 time=0.615 ms64 bytes from 2001:db8:bad:a55::2: icmp_seq=2 ttl=64 time=0.407 ms^C--- ios1 ping statistics ---2 packets transmitted, 2 received, 0% packet loss, time 1001msrtt min/avg/max/mdev = 0.407/0.511/0.615/0.104 ms That also looks promising to me. How about your configuration? Next, it might be interesting to extend the range of available services on the network. One essential service would be to have web sites at hand.

  • EM12c: Using the LIST verb in emcli

    - by SubinDaniVarughese
    Many of us who use EM CLI to write scripts and automate our daily tasks should not miss out on the new list verb released with Oracle Enterprise Manager 12.1.0.3.0. The combination of list and Jython based scripting support in EM CLI makes it easier to achieve automation for complex tasks with just a few lines of code. Before I jump into a script, let me highlight the key attributes of the list verb and why it’s simply excellent! 1. Multiple resources under a single verb:A resource can be set of users or targets, etc. Using the list verb, you can retrieve information about a resource from the repository database.Here is an example which retrieves the list of administrators within EM.Standard mode$ emcli list -resource="Administrators" Interactive modeemcli>list(resource="Administrators")The output will be the same as standard mode.Standard mode$ emcli @myAdmin.pyEnter password :  ******The output will be the same as standard mode.Contents of myAdmin.py scriptlogin()print list(resource="Administrators",jsonout=False).out()To get a list of all available resources use$ emcli list -helpWith every release of EM, more resources are being added to the list verb. If you have a resource which you feel would be valuable then go ahead and contact Oracle Support to log an enhancement request with product development. Be sure to say how the resource is going to help improve your daily tasks. 2. Consistent Formatting:It is possible to format the output of any resource consistently using these options:  –column  This option is used to specify which columns should be shown in the output. Here is an example which shows the list of administrators and their account status$ emcli list -resource="Administrators" -columns="USER_NAME,REPOS_ACCOUNT_STATUS" To get a list of columns in a resource use:$ emcli list -resource="Administrators" -help You can also specify the width of the each column. For example, here the column width of user_type is set to 20 and department to 30. $ emcli list -resource=Administrators -columns="USER_NAME,USER_TYPE:20,COST_CENTER,CONTACT,DEPARTMENT:30"This is useful if your terminal is too small or you need to fine tune a list of specific columns for your quick use or improved readability.  –colsize  This option is used to resize column widths.Here is the same example as above, but using -colsize to define the width of user_type to 20 and department to 30.$ emcli list -resource=Administrators -columns="USER_NAME,USER_TYPE,COST_CENTER,CONTACT,DEPARTMENT" -colsize="USER_TYPE:20,DEPARTMENT:30" The existing standard EMCLI formatting options are also available in list verb. They are: -format="name:pretty" | -format="name:script” | -format="name:csv" | -noheader | -scriptThere are so many uses depending on your needs. Have a look at the resources and columns in each resource. Refer to the EMCLI book in EM documentation for more information.3. Search:Using the -search option in the list verb makes it is possible to search for a specific row in a specific column within a resource. This is similar to the sqlplus where clause. The following operators are supported:           =           !=           >           <           >=           <=           like           is (Must be followed by null or not null)Here is an example which searches for all EM administrators in the marketing department located in the USA.$emcli list -resource="Administrators" -search="DEPARTMENT ='Marketing'" -search="LOCATION='USA'" Here is another example which shows all the named credentials created since a specific date.  $emcli list -resource=NamedCredentials -search="CredCreatedDate > '11-Nov-2013 12:37:20 PM'"Note that the timestamp has to be in the format DD-MON-YYYY HH:MI:SS AM/PM Some resources need a bind variable to be passed to get output. A bind variable is created in the resource and then referenced in the command. For example, this command will list all the default preferred credentials for target type oracle_database.Here is an example$ emcli list -resource="PreferredCredentialsDefault" -bind="TargetType='oracle_database'" -colsize="SetName:15,TargetType:15" You can provide multiple bind variables. To verify if a column is searchable or requires a bind variable, use the –help option. Here is an example:$ emcli list -resource="PreferredCredentialsDefault" -help 4. Secure accessWhen list verb collects the data, it only displays content for which the administrator currently logged into emcli, has access. For example consider this usecase:AdminA has access only to TargetA. AdminA logs into EM CLIExecuting the list verb to get the list of all targets will only show TargetA.5. User defined SQLUsing the –sql option, user defined sql can be executed. The SQL provided in the -sql option is executed as the EM user MGMT_VIEW, which has read-only access to the EM published MGMT$ database views in the SYSMAN schema. To get the list of EM published MGMT$ database views, go to the Extensibility Programmer's Reference book in EM documentation. There is a chapter about Using Management Repository Views. It’s always recommended to reference the documentation for the supported MGMT$ database views.  Consider you are using the MGMT$ABC view which is not in the chapter. During upgrade, it is possible, since the view was not in the book and not supported, it is likely the view might undergo a change in its structure or the data in it. Using a supported view ensures that your scripts using -sql will continue working after upgrade.Here’s an example  $ emcli list -sql='select * from mgmt$target' 6. JSON output support    JSON (JavaScript Object Notation) enables data to be displayed in a collection of name/value pairs. There is lot of reading material about JSON on line for more information.As an example, we had a requirement where an EM administrator had many 11.2 databases in their test environment and the developers had requested an Administrator to change the lifecycle status from Test to Production which meant the admin had to go to the EM “All targets” page and identify the set of 11.2 databases and then to go into each target database page and manually changes the property to Production. Sounds easy to say, but this Administrator had numerous targets and this task is repeated for every release cycle.We told him there is an easier way to do this with a script and he can reuse the script whenever anyone wanted to change a set of targets to a different Lifecycle status. Here is a jython script which uses list and JSON to change all 11.2 database target’s LifeCycle Property value.If you are new to scripting and Jython, I would suggest visiting the basic chapters in any Jython tutorials. Understanding Jython is important to write the logic depending on your usecase.If you are already writing scripts like perl or shell or know a programming language like java, then you can easily understand the logic.Disclaimer: The scripts in this post are subject to the Oracle Terms of Use located here.  1 from emcli import *  2  search_list = ['PROPERTY_NAME=\'DBVersion\'','TARGET_TYPE= \'oracle_database\'','PROPERTY_VALUE LIKE \'11.2%\'']  3 if len(sys.argv) == 2:  4    print login(username=sys.argv[0])  5    l_prop_val_to_set = sys.argv[1]  6      l_targets = list(resource="TargetProperties", search=search_list,   columns="TARGET_NAME,TARGET_TYPE,PROPERTY_NAME")  7    for target in l_targets.out()['data']:  8       t_pn = 'LifeCycle Status'  9      print "INFO: Setting Property name " + t_pn + " to value " +       l_prop_val_to_set + " for " + target['TARGET_NAME']  10      print  set_target_property_value(property_records=      target['TARGET_NAME']+":"+target['TARGET_TYPE']+":"+      t_pn+":"+l_prop_val_to_set)  11  else:  12   print "\n ERROR: Property value argument is missing"  13   print "\n INFO: Format to run this file is filename.py <username>   <Database Target LifeCycle Status Property Value>" You can download the script from here. I could not upload the file with .py extension so you need to rename the file to myScript.py before executing it using emcli.A line by line explanation for beginners: Line  1 Imports the emcli verbs as functions  2 search_list is a variable to pass to the search option in list verb. I am using escape character for the single quotes. In list verb to pass more than one value for the same option, you should define as above comma separated values, surrounded by square brackets.  3 This is an “if” condition to ensure the user does provide two arguments with the script, else in line #15, it prints an error message.  4 Logging into EM. You can remove this if you have setup emcli with autologin. For more details about setup and autologin, please go the EM CLI book in EM documentation.  5 l_prop_val_to_set is another variable. This is the property value to be set. Remember we are changing the value from Test to Production. The benefit of this variable is you can reuse the script to change the property value from and to any other values.  6 Here the output of the list verb is stored in l_targets. In the list verb I am passing the resource as TargetProperties, search as the search_list variable and I only need these three columns – target_name, target_type and property_name. I don’t need the other columns for my task.  7 This is a for loop. The data in l_targets is available in JSON format. Using the for loop, each pair will now be available in the ‘target’ variable.  8 t_pn is the “LifeCycle Status” variable. If required, I can have this also as an input and then use my script to change any target property. In this example, I just wanted to change the “LifeCycle Status”.  9 This a message informing the user the script is setting the property value for dbxyz.  10 This line shows the set_target_property_value verb which sets the value using the property_records option. Once it is set for a target pair, it moves to the next one. In my example, I am just showing three dbs, but the real use is when you have 20 or 50 targets. The script is executed as:$ emcli @myScript.py subin Production The recommendation is to first test the scripts before running it on a production system. We tested on a small set of targets and optimizing the script for fewer lines of code and better messaging.For your quick reference, the resources available in Enterprise Manager 12.1.0.4.0 with list verb are:$ emcli list -helpWatch this space for more blog posts using the list verb and EM CLI Scripting use cases.

  • Jquery fade and swap an element when clicked which will also relate to an accordian menu

    - by Nik
    You will notice when you click posture 1 the description drops down and images appear on the right. Now when you click posture 2 or posture 3 the images and description change as they should. What I need to do now is - If posture 1 has been clicked and then posture 2 is clicked the posture 1 menu needs to close so that there is only one posture description visible at one time. If I could also make it so that if the current open posture item is clicked so that it closes and there are no open posture descriptions that there also no images displayed on the right. Finally is there a way to make sure only one set of animation images is running, because just say the user goes through all 26 options and they continue to run in the background it may get sluggish (thanks to Nick Craver for bringing that up). At this stage only posture 1, 2 and 3 are available. Ok finally some code - //Description drop-down boxes $(document).ready(function(){ //Hide (Collapse) the toggle containers on load $(".toggle_container").hide(); //Switch the "Open" and "Close" state per click $("h5.trigger").toggle(function(){ $(this).addClass("active"); }, function () { $(this).removeClass("active"); }); //Slide up and down on click $("h5.trigger").click(function(){ $(this).next(".toggle_container").slideToggle("slow"); }); }); //Images on the right fade in and out thanks to aSeptik $(document).ready(function(){ $('#section_Q_01,#section_Q_02,#section_Q_03').hide(); $(function() { $('h5.trigger a').click( function(e) { e.preventDefault(); var trigger_id = $(this).parent().attr('id'); //get id Q_## $('.current').removeClass('current').hide(); //add a class for easy access & hide $('#section_' + trigger_id).addClass('current').fadeIn(5000); //show clicked one }); }); }); //Fading pics $(document).ready(function(){ $('.pics').cycle({ fx: 'fade', speed: 2500 }); }); Description boxes - <h5 class="trigger" id="Q_01" ><a href="#">Posture 1 : Standing Deep Breathing :</a></h5> <div class="toggle_container" > <div class="block"> <span class="sc">Pranayama Series</span> <p class="bold">Benefits:</p> </div> </div> <h5 class="trigger" id="Q_02" ><a href="#">Posture 2 : Half Moon Pose With Hands To Feet Pose :</a></h5> <div class="toggle_container"> <div class="block"> <span class="sc">Ardha Chandrasana with Pada-Hastasana</span> <p class="bold">Benefits:</p> </div> </div> <h5 class="trigger" id="Q_03" ><a href="#">Posture 3 : Awkward Pose :</a></h5> <div class="toggle_container"> <div class="block"> <span class="sc">Utkatasana</span> <p class="bold">Benefits:</p> </div> </div> and the images on the right - <div id="section_Q_01" class="01"> <div class="pics"> <img src="../images/multi/poses/pose1/Pranayama._01.jpg"/> <img src="../images/multi/poses/pose1/Pranayama._02.jpg"/> <img src="../images/multi/poses/pose1/Pranayama._03.jpg"/> </div> </div> <div id="section_Q_02" class="02"> <div class="pics"> <img src="../images/multi/poses/pose2/Half_Moon_Pose_04.jpg" /> <img src="../images/multi/poses/pose2/Backward_Bending_05.jpg" /> <img src="../images/multi/poses/pose2/Hands_to_Feet_Pose_06.jpg" /> </div> </div> <div id="section_Q_03" class="03"> <div class="pics"> <img src="../images/multi/poses/pose3/Awkward_01.jpg" /> <img src="../images/multi/poses/pose3/Awkward_02.jpg" /> <img src="../images/multi/poses/pose3/Awkward_03.jpg" /> </div> </div> It would be a bonus if images faded out when another element is clicked... but not a big deal. Thanks for having a look

  • Silverlight/Web Service Serializing Interface for use Client Side

    - by Steve Brouillard
    I have a Silverlight solution that references a third-party web service. This web service generates XML, which is then processed into objects for use in Silverlight binding. At one point we the processing of XML to objects was done client-side, but we ran into performance issues and decided to move this processing to the proxies in the hosting web project to improve performance (which it did). This is obviously a gross over-simplification, but should work. My basic project structure looks like this. Solution Solution.Web - Holds the web page that hosts Silverlight as well as proxies that access web services and processes as required and obviously the references to those web services). Solution.Infrastructure - Holds references to the proxy web services in the .Web project, all genned code from serialized objects from those proxies and code around those objects that need to be client-side. Solution.Book - The particular project that uses the objects in question after processed down into Infrastructure. I've defined the following Interface and Class in the Web project. They represent the type of objects that the XML from the original third-party gets transformed into and since this is the only project in the Silverlight app that is actually server-side, that was the place to define and use them. //Doesn't get much simpler than this. public interface INavigable { string Description { get; set; } } //Very simple class too public class IndexEntry : INavigable { public List<IndexCM> CMItems { get; set; } public string CPTCode { get; set; } public string DefinitionOfAbbreviations { get; set; } public string Description { get; set; } public string EtiologyCode { get; set; } public bool HighScore { get; set; } public IndexToTabularCommandArguments IndexToTabularCommandArgument { get; set; } public bool IsExpanded { get; set; } public string ManifestationCode { get; set; } public string MorphologyCode { get; set; } public List<TextItem> NonEssentialModifiersAndQualifyingText { get; set; } public string OtherItalics { get; set; } public IndexEntry Parent { get; set; } public int Score { get; set; } public string SeeAlsoReference { get; set; } public string SeeReference { get; set; } public List<IndexEntry> SubEntries { get; set; } public int Words { get; set; } } Again; both of these items are defined in the Web project. Notice that IndexEntry implments INavigable. When the code for IndexEntry is auto-genned in the Infrastructure project, the definition of the class does not include the implmentation of INavigable. After discovering this, I thought "no problem, I'll create another partial class file reiterating the implmentation". Unfortunately (I'm guessing because it isn't being serialized), that interface isn't recognized in the Infrastructure project, so I can't simply do that. Here's where it gets really weird. The BOOK project CAN see the INavigable interface. In fact I use it in Book, though Book has no reference to the Web Service in the Web project where the thing is define, though Infrastructure does. Just as a test, I linked to the INavigable source file from indside the Infrastructure project. That allowed me to reference it in that project and compile, but causes havoc in the Book project, because now there's a conflick between the one define in Infrastructure and the one defined in the Web project's web service. This is behavior I would expect. So, to try and sum up a bit. Web project has a web service that process data from a third-party service and has a class and interface defined in it. The class implements the interface. The Infrastructure project references the web service in the Web Project and the Book project references the Infrastructure project. The implmentation of the interface in the class does NOT serialize down, so the auto-genned code in INfrastructure does not show this relationship, breaking code further down-stream. The Book project, whihc is further down-stream CAN see the interface as defined in the Web Project, even though its only reference is through the Infrastructure project; whihc CAN'T see it. Am I simple missing something easy here? Can I apply an attribute to either the Interface definition or to the its implmentation in the class to ensure its visibility downstream? Anything else I can do here? I know this is a bit convoluted and anyone still with me here, thanks for your patience and any advice you might have. Cheers, Steve

  • Using CSS3 media queries in HTML 5 pages

    - by nikolaosk
    This is going to be the seventh post in a series of posts regarding HTML 5. You can find the other posts here , here , here, here , here and here. In this post I will provide a hands-on example on how to use CSS 3 Media Queries in HTML 5 pages. This is a very important feature since nowadays lots of users view websites through their mobile devices. Web designers were able to define media-specific style sheets for quite a while, but have been limited to the type of output. The output could only be Screen, Print .The way we used to do things before CSS 3 was to have separate CSS files and the browser decided which style sheet to use. Please have a look at the snippet below - HTML 4 media queries <link rel="stylesheet" type="text/css" media="screen" href="styles.css"> <link rel="stylesheet" type="text/css" media="print" href="print-styles.css"> ?he browser determines which style to use. With CSS 3 we can have all media queries in one stylesheet. Media queries can determine the resolution of the device, the orientation of the device, the width and height of the device and the width and height of the browser window.We can also include CSS 3 media queries in separate stylesheets. In order to be absolutely clear this is not (and could not be) a detailed tutorial on HTML 5. There are other great resources for that.Navigate to the excellent interactive tutorials of W3School. Another excellent resource is HTML 5 Doctor. Two very nice sites that show you what features and specifications are implemented by various browsers and their versions are http://caniuse.com/ and http://html5test.com/. At this times Chrome seems to support most of HTML 5 specifications.Another excellent way to find out if the browser supports HTML 5 and CSS 3 features is to use the Javascript lightweight library Modernizr. In this hands-on example I will be using Expression Web 4.0.This application is not a free application. You can use any HTML editor you like.You can use Visual Studio 2012 Express edition. You can download it here. Before I go on with the actual demo I will use the (http://www.caniuse.com) to see the support for CSS 3 Media Queries from the latest versions of modern browsers. Please have a look at the picture below. We see that all the latest versions of modern browsers support this feature. We can see that even IE 9 supports this feature.   Let's move on with the actual demo.  This is going to be a rather simple demo.I create a simple HTML 5 page. The markup follows and it is very easy to use and understand.This is a page with a 2 column layout. <!DOCTYPE html><html lang="en">  <head>    <title>HTML 5, CSS3 and JQuery</title>    <meta http-equiv="Content-Type" content="text/html;charset=utf-8" >    <link rel="stylesheet" type="text/css" href="style.css">       </head>  <body>    <div id="header">      <h1>Learn cutting edge technologies</h1>      <p>HTML 5, JQuery, CSS3</p>    </div>    <div id="main">      <div id="mainnews">        <div>          <h2>HTML 5</h2>        </div>        <div>          <p>            HTML5 is the latest version of HTML and XHTML. The HTML standard defines a single language that can be written in HTML and XML. It attempts to solve issues found in previous iterations of HTML and addresses the needs of Web Applications, an area previously not adequately covered by HTML.          </p>          <div class="quote">            <h4>Do More with Less</h4>            <p>             jQuery is a fast and concise JavaScript Library that simplifies HTML document traversing, event handling, animating, and Ajax interactions for rapid web development.             </p>            </div>          <p>            The HTML5 test(html5test.com) score is an indication of how well your browser supports the upcoming HTML5 standard and related specifications. Even though the specification isn't finalized yet, all major browser manufacturers are making sure their browser is ready for the future. Find out which parts of HTML5 are already supported by your browser today and compare the results with other browsers.                      The HTML5 test does not try to test all of the new features offered by HTML5, nor does it try to test the functionality of each feature it does detect. Despite these shortcomings we hope that by quantifying the level of support users and web developers will get an idea of how hard the browser manufacturers work on improving their browsers and the web as a development platform.</p>        </div>      </div>              <div id="CSS">        <div>          <h2>CSS 3 Intro</h2>        </div>        <div>          <p>          Cascading Style Sheets (CSS) is a style sheet language used for describing the presentation semantics (the look and formatting) of a document written in a markup language.

If this condition is true, then I add new rules for the body element. I change the number of columns to one. This rule will not be applied unless the maximum width is 480px or less.  As I decrease the size-width of the browser window I see no change in the column's layout. Have a look at the picture below. When I resize the window and the width of the browser so the width is less than 480px, the media query and its respective rules take effect.We can scroll vertically to view the content which is a more optimised viewing experience for mobile devices. Have a look at the picture below Hope it helps!!!!

  • Embedding mercurial revision information in Visual Studio c# projects automatically

    - by Mark Booth
    Original Problem In building our projects, I want the mercurial id of each repository to be embedded within the product(s) of that repository (the library, application or test application). I find it makes it so much easier to debug an application ebing run by custiomers 8 timezones away if you know precisely what went into building the particular version of the application they are using. As such, every project (application or library) in our systems implement a way of getting at the associated revision information. I also find it very useful to be able to see if an application has been compiled with clean (un-modified) changesets from the repository. 'Hg id' usefully appends a + to the changeset id when there are uncommitted changes in a repository, so this allows is to easily see if people are running a clean or a modified version of the code. My current solution is detailed below, and fulfills the basic requirements, but there are a number of problems with it. Current Solution At the moment, to each and every Visual Studio solution, I add the following "Pre-build event command line" commands: cd $(ProjectDir) HgID I also add an HgID.bat file to the Project directory: @echo off type HgId.pre > HgId.cs For /F "delims=" %%a in ('hg id') Do <nul >>HgID.cs set /p = @"%%a" echo ; >> HgId.cs echo } >> HgId.cs echo } >> HgId.cs along with an HgId.pre file, which is defined as: namespace My.Namespace { /// <summary> Auto generated Mercurial ID class. </summary> internal class HgID { /// <summary> Mercurial version ID [+ is modified] [Named branch]</summary> public const string Version = When I build my application, the pre-build event is triggered on all libraries, creating a new HgId.cs file (which is not kept under revision control) and causing the library to be re-compiled with with the new 'hg id' string in 'Version'. Problems with the current solution The main problem is that since the HgId.cs is re-created at each pre-build, every time we need to compile anything, all projects in the current solution are re-compiled. Since we want to be able to easily debug into our libraries, we usually keep many libraries referenced in our main application solution. This can result in build times which are significantly longer than I would like. Ideally I would like the libraries to compile only if the contents of the HgId.cs file has actually changed, as opposed to having been re-created with exactly the same contents. The second problem with this method is it's dependence on specific behaviour of the windows shell. I've already had to modify the batch file several times, since the original worked under XP but not Vista, the next version worked under Vista but not XP and finally I managed to make it work with both. Whether it will work with Windows 7 however is anyones guess and as time goes on, I see it more likely that contractors will expect to be able to build our apps on their Windows 7 boxen. Finally, I have an aesthetic problem with this solution, batch files and bodged together template files feel like the wrong way to do this. My actual questions How would you solve/how are you solving the problem I'm trying to solve? What better options are out there than what I'm currently doing? Rejected Solutions to these problems Before I implemented the current solution, I looked at Mercurials Keyword extension, since it seemed like the obvious solution. However the more I looked at it and read peoples opinions, the more that I came to the conclusion that it wasn't the right thing to do. I also remember the problems that keyword substitution has caused me in projects at previous companies (just the thought of ever having to use Source Safe again fills me with a feeling of dread *8'). Also, I don't particularly want to have to enable Mercurial extensions to get the build to complete. I want the solution to be self contained, so that it isn't easy for the application to be accidentally compiled without the embedded version information just because an extension isn't enabled or the right helper software hasn't been installed. I also thought of writing this in a better scripting language, one where I would only write HgId.cs file if the content had actually changed, but all of the options I could think of would require my co-workers, contractors and possibly customers to have to install software they might not otherwise want (for example cygwin). Any other options people can think of would be appreciated. Update Partial solution Having played around with it for a while, I've managed to get the HgId.bat file to only overwrite the HgId.cs file if it changes: @echo off type HgId.pre > HgId.cst For /F "delims=" %%a in ('hg id') Do <nul >>HgId.cst set /p = @"%%a" echo ; >> HgId.cst echo } >> HgId.cst echo } >> HgId.cst fc HgId.cs HgId.cst >NUL if %errorlevel%==0 goto :ok copy HgId.cst HgId.cs :ok del HgId.cst Problems with this solution Even though HgId.cs is no longer being re-created every time, Visual Studio still insists on compiling everything every time. I've tried looking for solutions and tried checking "Only build startup projects and dependencies on Run" in Tools|Options|Projects and Solutions|Build and Run but it makes no difference. The second problem also remains, and now I have no way to test if it will work with Vista, since that contractor is no longer with us. If anyone can test this batch file on a Windows 7 and/or Vista box, I would appreciate hearing how it went. Finally, my aesthetic problem with this solution, is even strnger than it was before, since the batch file is more complex and this there is now more to go wrong. If you can think of any better solution, I would love to hear about them.

  • 12c - flashforward, flashback or see it as of now...

    - by noreply(at)blogger.com (Thomas Kyte)
    Oracle 9i exposed flashback query to developers for the first time.  The ability to flashback query dates back to version 4 however (it just wasn't exposed).  Every time you run a query in Oracle it is in fact a flashback query - it is what multi-versioning is all about.However, there was never a flashforward query (well, ok, the workspace manager has this capability - but with lots of extra baggage).  We've never been able to ask a table "what will you look like tomorrow" - but now we do.The capability is called Temporal Validity.  If you have a table with data that is effective dated - has a "start date" and "end date" column in it - we can now query it using flashback query like syntax.  The twist is - the date we "flashback" to can be in the future.  It works by rewriting the query to transparently the necessary where clause and filter out the right rows for the right period of time - and since you can have records whose start date is in the future - you can query a table and see what it would look like at some future time.Here is a quick example, we'll start with a table:ops$tkyte%ORA12CR1> create table addresses  2  ( empno       number,  3    addr_data   varchar2(30),  4    start_date  date,  5    end_date    date,  6    period for valid(start_date,end_date)  7  )  8  /Table created.the new bit is on line 6 (it can be altered into an existing table - so any table  you have with a start/end date column will be a candidate).  The keyword is PERIOD, valid is an identifier I chose - it could have been foobar, valid just sounds nice in the query later.  You identify the columns in your table - or we can create them for you if they don't exist.  Then you just create some data:ops$tkyte%ORA12CR1> insert into addresses (empno, addr_data, start_date, end_date )  2  values ( 1234, '123 Main Street', trunc(sysdate-5), trunc(sysdate-2) );1 row created.ops$tkyte%ORA12CR1>ops$tkyte%ORA12CR1> insert into addresses (empno, addr_data, start_date, end_date )  2  values ( 1234, '456 Fleet Street', trunc(sysdate-1), trunc(sysdate+1) );1 row created.ops$tkyte%ORA12CR1>ops$tkyte%ORA12CR1> insert into addresses (empno, addr_data, start_date, end_date )  2  values ( 1234, '789 1st Ave', trunc(sysdate+2), null );1 row created.and you can either see all of the data:ops$tkyte%ORA12CR1> select * from addresses;     EMPNO ADDR_DATA                      START_DAT END_DATE---------- ------------------------------ --------- ---------      1234 123 Main Street                27-JUN-13 30-JUN-13      1234 456 Fleet Street               01-JUL-13 03-JUL-13      1234 789 1st Ave                    04-JUL-13or query "as of" some point in time - as  you can see in the predicate section - it is just doing a query rewrite to automate the "where" filters:ops$tkyte%ORA12CR1> select * from addresses as of period for valid sysdate-3;     EMPNO ADDR_DATA                      START_DAT END_DATE---------- ------------------------------ --------- ---------      1234 123 Main Street                27-JUN-13 30-JUN-13ops$tkyte%ORA12CR1> @planops$tkyte%ORA12CR1> select * from table(dbms_xplan.display_cursor);PLAN_TABLE_OUTPUT-------------------------------------------------------------------------------SQL_ID  cthtvvm0dxvva, child number 0-------------------------------------select * from addresses as of period for valid sysdate-3Plan hash value: 3184888728-------------------------------------------------------------------------------| Id  | Operation         | Name      | Rows  | Bytes | Cost (%CPU)| Time     |-------------------------------------------------------------------------------|   0 | SELECT STATEMENT  |           |       |       |     3 (100)|          ||*  1 |  TABLE ACCESS FULL| ADDRESSES |     1 |    48 |     3   (0)| 00:00:01 |-------------------------------------------------------------------------------Predicate Information (identified by operation id):---------------------------------------------------   1 -

  • Tips for XNA WP7 Developers

    - by Michael B. McLaughlin
    There are several things any XNA developer should know/consider when coming to the Windows Phone 7 platform. This post assumes you are familiar with the XNA Framework and with the changes between XNA 3.1 and XNA 4.0. It’s not exhaustive; it’s simply a list of things I’ve gathered over time. I may come back and add to it over time, and I’m happy to add anything anyone else has experienced or learned as well. Display · The screen is either 800x480 or 480x800. · But you aren’t required to use only those resolutions. · The hardware scaler on the phone will scale up from 240x240. · One dimension will be capped at 800 and the other at 480; which depends on your code, but you cannot have, e.g., an 800x600 back buffer – that will be created as 800x480. · The hardware scaler will not normally change aspect ratio, though, so no unintended stretching. · Any dimension (width, height, or both) below 240 will be adjusted to 240 (without any aspect ratio adjustment such that, e.g. 200x240 will be treated as 240x240). · Dimensions below 240 will be honored in terms of calculating whether to use portrait or landscape. · If dimensions are exactly equal or if height is greater than width then game will be in portrait. · If width is greater than height, the game will be in landscape. · Landscape games will automatically flip if the user turns the phone 180°; no code required. · Default landscape is top = left. In other words a user holding a phone who starts a landscape game will see the first image presented so that the “top” of the screen is along the right edge of his/her phone, such that the natural behavior would be to turn the phone 90° so that the top of the phone will be held in the user’s left hand and the bottom would be held in the user’s right hand. · The status bar (where the clock, battery power, etc., are found) is hidden when the Game-derived class sets GraphicsDeviceManager.IsFullScreen = true. It is shown when IsFullScreen = false. The default value is false (i.e. the status bar is shown). · You should have a good reason for hiding the status bar. Users find it helpful to know what time it is, how much charge their battery has left, and whether or not their phone is in service range. This is especially true for casual games that you expect someone to play for a few minutes at a time, e.g. while waiting for some event to start, for a phone call to come in, or for a train, bus, or subway to arrive. · In portrait mode, the status bar occupies 32 pixels of space. This means that a game with a back buffer of 480x800 will be scaled down to occupy approximately 461x768 screen pixels. Setting the back buffer to 480x768 (or some resolution with the same 0.625 aspect ratio) will avoid this scaling. · In landscape mode, the status bar occupies 72 pixels of space. This means that a game with a back buffer of 800x480 will be scaled down to occupy approximately 728x437 screen pixels. Setting the back buffer to 728x480 (or some resolution with the same 1.51666667 aspect ratio) will avoid this scaling. Input · Touch input is scaled with screen size. · So if your back buffer is 600x360, a tap in the bottom right corner will come in as (599,359). You don’t need to do anything special to get this automatic scaling of touch behavior. · If you do not use full area of the screen, any touch input outside the area you use will still register as a touch input. For example, if you set a portrait resolution of 240x240, it would be scaled up to occupy a 480x480 area, centered in the screen. If you touch anywhere above this area, you will get a touch input of (X,0) where X is a number from 0 to 239 (in accordance with your 240 pixel wide back buffer). Any touch below this area will give a touch input of (X,239). · If you keep the status bar visible, touches within its area will not be passed to your game. · In general, a screen measurement is the diagonal. So a 3.5” screen is 3.5” long from the bottom right corner to the top left corner. With an aspect ratio of 0.6 (480/800 = 0.6), this means that a phone with a 3.5” screen is only approximately 1.8” wide by 3” tall. So there are approximately 267 pixels in an inch on a 3.5” screen. · Again, this time in metric! 3.5 inches is approximately 8.89 cm. So an 8.89 cm screen is 8.89 cm long from the bottom right corner to the top left corner. With an aspect ratio of 0.6, this means that a phone with an 8.89 cm screen is only approximately 4.57 cm wide by 7.62 cm tall. So there are approximately 105 pixels in a centimeter on an 8.89 cm screen. · Think about the size of your finger tip. If you do not have large hands, think about the size of the fingertip of someone with large hands. Consider that when you are sizing your touch input. Especially consider that when you are spacing two touch targets near one another. You need to judge it for yourself, but items that are next to each other and are each 100x100 should be fine when it comes to selecting items individually. Smaller targets than that are ok provided that you leave space between them. · You want your users to have a pleasant experience. Making touch controls too small or too close to one another will make them nervous about whether they will touch the right target. Take this into account when you plan out your game initially. If possible, do some quick size mockups on an actual phone using colored rectangles that you position and size where you plan to have your game controls. Adjust as necessary. · People do not have transparent hands! Nor are their hands the size of a mouse pointer icon. Consider leaving a dedicated space for input rather than forcing the user to cover up to one-third of the screen with a finger just to play the game. · Another benefit of designing your controls to use a dedicated area is that you’re less likely to have players moving their finger(s) so frantically that they accidentally hit the back button, start button, or search button (many phones have one or more of these on the screen itself – it’s easy to hit one by accident and really annoying if you hit, e.g., the search button and then quickly tap back only to find out that the game didn’t save your progress such that you just wasted all the time you spent playing). · People do not like doing somersaults in order to move something forward with accelerometer-based controls. Test your accelerometer-based controls extensively and get a lot of feedback. Very well-known games from noted publishers have created really bad accelerometer controls and been virtually unplayable as a result. Also be wary of exceptions and other possible failures that the documentation warns about. · When done properly, the accelerometer can add a nice touch to your game (see, e.g. ilomilo where the accelerometer was used to move the background; it added a nice touch without frustrating the user; I also think CarniVale does direct accelerometer controls very well). However, if done poorly, it will make your game an abomination unto the Marketplace. Days, weeks, perhaps even months of development time that you will never get back. I won’t name names; you can search the marketplace for games with terrible reviews and you’ll find them. Graphics · The maximum frame rate is 30 frames per second. This was set as a compromise between battery life and quality. · At least one model of phone is known to have a screen refresh rate that is between 59 and 60 hertz. Because of this, using a fixed time step with a target frame rate of 30 will cause a slight internal delay to build up as the framework is forced to wait slightly for the next refresh. Eventually the delay will get to the point where a draw is skipped in order to recover from the delay. (See Nick's comment below for clarification.) · To deal with that delay, you can either stay with a fixed time step and set the frame rate slightly lower or else you can go to a variable time step and make sure to adjust all of your update data (e.g. player movement distance) to take into account the elapsed time from the last update. A variable time step makes your update logic slightly more complicated but will avoid frame skips entirely. · Currently there are no custom shaders. This might change in the future (there is no hardware limitation preventing it; it simply wasn’t a feature that could be implemented in the time available before launch). · There are five built-in shaders. You can create a lot of nice effects with the built-in shaders. · There is more power on the CPU than there is on the GPU so things you might typically off-load to the GPU will instead make sense to do on the CPU side. · This is a phone. It is not a PC. It is not an Xbox 360. The emulator runs on a PC and uses the full power of your PC. It is very good for testing your code for bugs and doing early prototyping and layout. You should not use it to measure performance. Use actual phone hardware instead. · There are many phone models, each of which has slightly different performance levels for I/O, screen blitting, CPU performance, etc. Do not take your game right to the performance limit on your phone since for some other phones you might be crossing their limits and leaving players with a bad experience. Leave a cushion to account for hardware differences. · Smaller screened phones will have slightly more dots per inch (dpi). Larger screened phones will have slightly less. Either way, the dpi will be much higher than the typical 96 found on most computer screens. Make sure that whoever is doing art for your game takes this into account. · Screens are only required to have 16 bit color (65,536 colors). This is common among smart phones. Using gradients on a 16 bit display can produce an ugly artifact known as banding. Banding is when, rather than a smooth transition from one color to another, you instead see distinct lines. Be careful to avoid this when possible. Banding can be avoided through careful art creation. Its effects can be minimized and even unnoticeable when the texture in question is always moving. You should be careful not to rely on “looks good on my phone” since some phones do have 32-bit displays and thus you’ll find yourself wondering why you’re getting bad reviews that complain about the graphics. Avoid gradients; if you can’t, make sure they are 16-bit safe. Audio · Never rely on sounds as your sole signal to the player that something is happening in the game. They might have the sound off. They might be playing somewhere loud. Etc. · You have to provide controls to disable sound & music. These should be separate. · On at least one model of phone, the volume control API currently has no effect. Players can adjust sound with their hardware volume buttons, but in game selectors simply won’t work. As such, it may not be worth the effort of providing anything beyond on/off switches for sound and music. · MediaPlayer.GameHasControl will return true when a game is hooked up to a PC running Zune. When Zune is running, any attempts to do anything (beyond check GameHasControl) with MediaPlayer will cause an exception to be thrown. If this exception is thrown, catch it and disable music. Exceptions take time to propagate; you don’t want one popping up in every single run of your game’s Update method. · Remember that players can already be listening to music or using the FM radio. In this case GameHasControl will be false and you should handle this appropriately. You can, alternately, ask the player for permission to stop their current music and play your music instead, but the (current) requirement that you restore their music when done is very hard (if not impossible) to deal with. · You can still play sound effects even when the game doesn’t have control of the music, but don’t think this is a backdoor to playing music. Your game will fail certification if your “sound effect” seems to be more like music in scope and length.

  • Ruby number_to_currency displays a totally wrong number!

    - by SueP
    Greetings! I’m an old Delphi programmer making the leap to the Mac, Ruby, Rails, and web programming in general. I’m signed up for the Advanced Rails workshop at the end of the month. In the meantime, I’ve been working on porting a mission-critical (of course) app from Delphi to RAILS. It feels like I’ve spent most of the past year with my head buried in a book or podcast. Right now, I’ve hit a major issue and I’m tearing my hair out. I literally don’t know where to go with this, I desperately don’t want to deploy with this bug, and I’m feeling a bit frantic. (The company database is currently running on an ancient XP box that’s looking rustier by the day.) So, I set up a test database that shows the problem. I’m running: OS/X 10.6.3 Rails 2.3.5 ruby 1.8.7 (2009-06-08 patchlevel 173) [universal-darwin10.0] MySQL 5.1.38-log via socket MySQL Client Version 5.1.8 ActiveRecord::Schema.define(:version => 20100406222528) do create_table “money”, :force => true do |t| t.decimal “amount_due”, :precision => 10, :scale => 2, :default => 0.0 t.decimal “balance”, :precision => 10, :scale => 2, :default => 0.0 t.text “memofield” t.datetime “created_at” t.datetime “updated_at” end The index view is right out of the generator, slightly modified to add the formatting that's breaking on me. Listing money <table> <tr> <th>Amount</th> <th>Amount to_s </th> <th>Balance to $</th> <th>Balance with_precision </th> <th>Memofield</th> </tr> <% @money.each do |money| %> <tr> <td><%=h money.amount_due %></td> <td><%=h money.amount_due.to_s(‘F’) %></td> <td><%=h number_to_currency(money.balance) %></td> <td><%=h number_with_precision(money.balance, :precision => 2) %></td> <td><%=h money.memofield %></td> <td><%= link_to ‘Show’, money %></td> <td><%= link_to ‘Edit’, edit_money_path(money) %></td> <td><%= link_to ‘Destroy’, money, :confirm => ‘Are you sure?’, :method => :delete %></td> </tr> *<% end %> *</table> <%= link_to ‘New money’, new_money_path %> This seemed to work pretty well. Then I started testing with production data and hit a major problem with number_to_currency. The number in the database is: 10542.28, I verified it with the MySQL Query Browser. RAILS will display this as 10542.28 unless I call number_to_currency, then that number is displayed as: $15422.80 The error seems to happen with any number between 10,000.00 and 10,999.99 So far, I haven’t seen it outside of that range, but I obviously haven’t tested everything. I guess my workaround is to remove number_to_currency, but that leaves the views looking really sloppy and unprofessional. The formatting is messed up, things don’t line up properly and I can’t force the display to 2 decimal places. I’m seriously hoping there is an easy fix for this. I can’t imagine this being a widespread problem. It would affect so many people that someone would have fixed it! But I don’t know where to go from here. I’d desperately like some help. (Later – number_with_precision fails the same way number_to_currency does.) Sue Petersen

  • WPF Some styles not applied on DataTemplate controls

    - by Martin
    Hi, I am trying to learn something about WPF and I am quite amazed by its flexibility. However, I have hit a problem with Styles and DataTemplates, which is little bit confusing. I have defined below test page to play around a bit with styles etc and found that the Styles defined in <Page.Resources> for Border and TextBlock are not applied in the DataTemplate, but Style for ProgressBar defined in exactly the same way is applied. Source code (I just use Kaxaml and XamlPadX to view the result) <Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <Page.Resources> <Style TargetType="{x:Type Border}"> <Setter Property="Background" Value="SkyBlue"/> <Setter Property="BorderBrush" Value="Black"/> <Setter Property="BorderThickness" Value="2"/> <Setter Property="CornerRadius" Value="5"/> </Style> <Style TargetType="{x:Type TextBlock}"> <Setter Property="FontWeight" Value="Bold"/> </Style> <Style TargetType="{x:Type ProgressBar}"> <Setter Property="Height" Value="10"/> <Setter Property="Width" Value="100"/> <Setter Property="Foreground" Value="Red"/> </Style> <XmlDataProvider x:Key="TestData" XPath="/TestData"> <x:XData> <TestData xmlns=""> <TestElement> <Name>Item 1</Name> <Value>25</Value> </TestElement> <TestElement> <Name>Item 2</Name> <Value>50</Value> </TestElement> </TestData> </x:XData> </XmlDataProvider> <HierarchicalDataTemplate DataType="TestElement"> <Border Height="45" Width="120" Margin="5,5"> <StackPanel Orientation="Vertical" Margin="5,5" VerticalAlignment="Center" HorizontalAlignment="Center"> <TextBlock HorizontalAlignment="Center" Text="{Binding XPath=Name}"/> <ProgressBar Value="{Binding XPath=Value}"/> </StackPanel> </Border> </HierarchicalDataTemplate> </Page.Resources> <StackPanel Orientation="Horizontal" HorizontalAlignment="Center" VerticalAlignment="Center"> <StackPanel Orientation="Vertical" VerticalAlignment="Center"> <Border Height="45" Width="120" Margin="5,5"> <StackPanel Orientation="Vertical" VerticalAlignment="Center" HorizontalAlignment="Center"> <TextBlock HorizontalAlignment="Center" Text="Item 1"/> <ProgressBar Value="25"/> </StackPanel> </Border> <Border Height="45" Width="120" Margin="5,5"> <StackPanel Orientation="Vertical" VerticalAlignment="Center" HorizontalAlignment="Center"> <TextBlock HorizontalAlignment="Center" Text="Item 2"/> <ProgressBar Value="50"/> </StackPanel> </Border> </StackPanel> <ListBox Margin="10,10" Width="140" ItemsSource="{Binding Source={StaticResource TestData}, XPath=TestElement}"/> </StackPanel> </Page> I suspect it has something to do with default styles etc, but more puzzling is why some Styles are applied and some not. I cannot find an easy explanation for above anywhere and thus would like to ask if someone would be kind enough to explain this behaviour in lamens' terms with possible links to technical description, i.e. to MSDN or so. Thanks in advance for you support!

  • VB.NET - using textfile as source for menus and textboxes

    - by Kenny Bones
    Hi, this is probably a bit tense and I'm not sure if this is possible at all. But basically, I'm trying to create a small application which contains alot of PowerShell-code which I want to run in an easy matter. I've managed to create everything myself and it does work. But all of the PowerShell code is manually hardcoded and this gives me a huge disadvantage. What I was thinking was creating some sort of dynamic structure where I can read a couple of text files (possible a numerous amount of text files) and use these as the source for both the comboboxes and the richtextbox which provovides as the string used to run in PowerShell. I was thinking something like this: Combobox - "Choose cmdlet" - Use "menucode.txt" as source Richtextbox - Use "code.txt" as source But, the thing is, Powershell snippets need a few arguments in order for them to work. So I've got a couple of comboboxes and a few textboxes which provides as input for these arguments. And this is done manually as it is right now. So rewriting this small application should also search the textfile for some keywords and have the comboboxes and textboxes to replace those keywords. And I'm not sure how to do this. So, would this requre a whole lot of textfiles? Or could I use one textfile and separate each PowerShell cmdlet snippets with something? Like some sort of a header? Right now, I've got this code at the eventhandler (ComboBox_SelectedIndexChanged) If ComboBoxFunksjon.Text = "Set attribute" Then TxtBoxUsername.Visible = True End If If chkBoxTextfile.Checked = True Then If txtboxBrowse.Text = "" Then MsgBox("You haven't choses a textfile as input for usernames") End If LabelAttribute.Visible = True LabelUsername.Visible = False ComboBoxAttribute.Visible = True TxtBoxUsername.Visible = False txtBoxCode.Text = "$users = Get-Content " & txtboxBrowse.Text & vbCrLf & "foreach ($a in $users)" & vbCrLf & "{" & vbCrLf & "Set-QADUser -Identity $a -ObjectAttributes @{" & ComboBoxAttribute.SelectedItem & "='" & TxtBoxValue.Text & "'}" & vbCrLf & "}" If ComboBoxAttribute.SelectedItem = "Outlook WebAccess" Then TxtBoxValue.Visible = False CheckBoxValue.Visible = True CheckBoxValue.Text = "OWA Enabled?" txtBoxCode.Text = "$users = Get-Content " & txtboxBrowse.Text & vbCrLf & "foreach ($a in $users)" & vbCrLf & "{" & vbCrLf & "Set-CASMailbox -Identity $a -OWAEnabled" & " " & "$" & CheckBoxValue.Checked & " '}" & vbCrLf & "}" End If If ComboBoxAttribute.SelectedItem = "MobileSync" Then TxtBoxValue.Visible = False CheckBoxValue.Visible = True CheckBoxValue.Text = "MobileSync Enabled?" Dim value If CheckBoxValue.Checked = True Then value = "0" Else value = "7" End If txtBoxCode.Text = "$users = Get-Content " & txtboxBrowse.Text & vbCrLf & "foreach ($a in $users)" & vbCrLf & "{" & vbCrLf & "Set-QADUser -Identity $a -ObjectAttributes @{msExchOmaAdminWirelessEnable='" & value & " '}" & vbCrLf & "}" End If Else LabelAttribute.Visible = True LabelUsername.Visible = True ComboBoxAttribute.Visible = True txtBoxCode.Text = "Set-QADUser -Identity " & TxtBoxUsername.Text & " -ObjectAttributes @{" & ComboBoxAttribute.SelectedItem & "='" & TxtBoxValue.Text & " '}" If ComboBoxAttribute.SelectedItem = "Outlook WebAccess" Then TxtBoxValue.Visible = False CheckBoxValue.Visible = True CheckBoxValue.Text = "OWA Enabled?" txtBoxCode.Text = "Set-CASMailbox " & TxtBoxUsername.Text & " -OWAEnabled " & "$" & CheckBoxValue.Checked End If If ComboBoxAttribute.SelectedItem = "MobileSync" Then TxtBoxValue.Visible = False CheckBoxValue.Visible = True CheckBoxValue.Text = "MobileSync Enabled?" Dim value If CheckBoxValue.Checked = True Then value = "0" Else value = "7" End If txtBoxCode.Text = "Set-QADUser " & TxtBoxUsername.Text & " -ObjectAttributes @{msExchOmaAdminWirelessEnable='" & value & "'}" End If End If Now, this snippet above lets me either use a text file as a source for each username used in the powershell snippet. Just so you know :) And I know, this is probably coded as stupidly as it gets. But it does work! :)

  • Selling Federal Enterprise Architecture (EA)

    - by TedMcLaughlan
    Selling Federal Enterprise Architecture A taxonomy of subject areas, from which to develop a prioritized marketing and communications plan to evangelize EA activities within and among US Federal Government organizations and constituents. Any and all feedback is appreciated, particularly in developing and extending this discussion as a tool for use – more information and details are also available. "Selling" the discipline of Enterprise Architecture (EA) in the Federal Government (particularly in non-DoD agencies) is difficult, notwithstanding the general availability and use of the Federal Enterprise Architecture Framework (FEAF) for some time now, and the relatively mature use of the reference models in the OMB Capital Planning and Investment (CPIC) cycles. EA in the Federal Government also tends to be a very esoteric and hard to decipher conversation – early apologies to those who agree to continue reading this somewhat lengthy article. Alignment to the FEAF and OMB compliance mandates is long underway across the Federal Departments and Agencies (and visible via tools like PortfolioStat and ITDashboard.gov – but there is still a gap between the top-down compliance directives and enablement programs, and the bottom-up awareness and effective use of EA for either IT investment management or actual mission effectiveness. "EA isn't getting deep enough penetration into programs, components, sub-agencies, etc.", verified a panelist at the most recent EA Government Conference in DC. Newer guidance from OMB may be especially difficult to handle, where bottom-up input can't be accurately aligned, analyzed and reported via standardized EA discipline at the Agency level – for example in addressing the new (for FY13) Exhibit 53D "Agency IT Reductions and Reinvestments" and the information required for "Cloud Computing Alternatives Evaluation" (supporting the new Exhibit 53C, "Agency Cloud Computing Portfolio"). Therefore, EA must be "sold" directly to the communities that matter, from a coordinated, proactive messaging perspective that takes BOTH the Program-level value drivers AND the broader Agency mission and IT maturity context into consideration. Selling EA means persuading others to take additional time and possibly assign additional resources, for a mix of direct and indirect benefits – many of which aren't likely to be realized in the short-term. This means there's probably little current, allocated budget to work with; ergo the challenge of trying to sell an "unfunded mandate". Also, the concept of "Enterprise" in large Departments like Homeland Security tends to cross all kinds of organizational boundaries – as Richard Spires recently indicated by commenting that "...organizational boundaries still trump functional similarities. Most people understand what we're trying to do internally, and at a high level they get it. The problem, of course, is when you get down to them and their system and the fact that you're going to be touching them...there's always that fear factor," Spires said. It is quite clear to the Federal IT Investment community that for EA to meet its objective, understandable, relevant value must be measured and reported using a repeatable method – as described by GAO's recent report "Enterprise Architecture Value Needs To Be Measured and Reported". What's not clear is the method or guidance to sell this value. In fact, the current GAO "Framework for Assessing and Improving Enterprise Architecture Management (Version 2.0)", a.k.a. the "EAMMF", does not include words like "sell", "persuade", "market", etc., except in reference ("within Core Element 19: Organization business owner and CXO representatives are actively engaged in architecture development") to a brief section in the CIO Council's 2001 "Practical Guide to Federal Enterprise Architecture", entitled "3.3.1. Develop an EA Marketing Strategy and Communications Plan." Furthermore, Core Element 19 of the EAMMF is advised to be applied in "Stage 3: Developing Initial EA Versions". This kind of EA sales campaign truly should start much earlier in the maturity progress, i.e. in Stages 0 or 1. So, what are the understandable, relevant benefits (or value) to sell, that can find an agreeable, participatory audience, and can pave the way towards success of a longer-term, funded set of EA mechanisms that can be methodically measured and reported? Pragmatic benefits from a useful EA that can help overcome the fear of change? And how should they be sold? Following is a brief taxonomy (it's a taxonomy, to help organize SME support) of benefit-related subjects that might make the most sense, in creating the messages and organizing an initial "engagement plan" for evangelizing EA "from within". An EA "Sales Taxonomy" of sorts. We're not boiling the ocean here; the subjects that are included are ones that currently appear to be urgently relevant to the current Federal IT Investment landscape. Note that successful dialogue in these topics is directly usable as input or guidance for actually developing early-stage, "Fit-for-Purpose" (a DoDAF term) Enterprise Architecture artifacts, as prescribed by common methods found in most EA methodologies, including FEAF, TOGAF, DoDAF and our own Oracle Enterprise Architecture Framework (OEAF). The taxonomy below is organized by (1) Target Community, (2) Benefit or Value, and (3) EA Program Facet - as in: "Let's talk to (1: Community Member) about how and why (3: EA Facet) the EA program can help with (2: Benefit/Value)". Once the initial discussion targets and subjects are approved (that can be measured and reported), a "marketing and communications plan" can be created. A working example follows the Taxonomy.

Program Costs – EA enables sound decisions regarding... 2.1.1. Cost Avoidance – a TCO theme 2.1.2. Sequencing – alignment of capability delivery 2.1.3. Budget Instability – a Federal reality 2.2. Investment Capital – EA illuminates new investment resources via... 2.2.1. Value Engineering – contractor-driven cost savings on existing budgets, direct or collateral 2.2.2.

What-If Scenarios – can become much more refined, current, verifiable; basis for Target Architectures 2.4. Mission Performance – EA enables beneficial decision results regarding... 2.4.1. IT Performance and Optimization – towards 100% effective, available resource utilization 2.4.2. IT Stability – towards 100%, real-time uptime 2.4.3. Agility – responding to rapid changes in mission 2.4.4. Outcomes –measures of mission success, KPIs – vs. only "Outputs" 2.4.5. Constraints – appropriate response to constraints 2.4.6.

Compliance – all the right boxes are checked 2.5.2. Dependencies –cross-agency, segment, government 2.5.3. Transparency – risks, impact and resource utilization are illuminated quickly, comprehensively 2.5.4. Threats and Vulnerabilities – current, realistic awareness and profiles 2.5.5. Consequences – realization of risk can be mapped as a series of consequences, from earlier decisions or new decisions required for current issues 2.5.5.1. Unanticipated – illuminating signals of future or non-symmetric risk; helping to "future-proof" 2.5.5.2. Anticipated – discovering the level of impact that matters 3. EA Program Facet (What parts of the EA can and should be communicated, using business or mission terms?) 3.1. Architecture Models – the visual tools to be created and used 3.1.1. Operating Architecture – the Business Operating Model/Architecture elements of the EA truly drive all other elements, plus expose communication channels 3.1.2. Use Of – how can the EA models be used, and how are they populated, from a reasonable, pragmatic yet compliant perspective? What are the core/minimal models required? What's the relationship of these models, with existing system models? 3.1.3. Scope – what level of granularity within the models, and what level of abstraction across the models, is likely to be most effective and useful? 3.2. Traceability – the maturity, status, completeness of the tools 3.2.1. Status – what in fact is the degree of maturity across the integrated EA model and other relevant governance models, and who may already be benefiting from it? 3.2.2. Visibility – how does the EA visibly and effectively prove IT investment performance goals are being reached, with positive mission outcome? 3.3. Governance – what's the interaction, participation method; how are the tools used? 3.3.1. Contributions – how is the EA program informed, accept submissions, collect data? Who are the experts? 3.3.2. Review – how is the EA validated, against what criteria?  Taxonomy Usage Example:   1. To speak with: a. ...a particular set of System Owners Facing Strategic Change, via mandate (like the "Cloud First" mandate); about... b. ...how the EA program's visible and easily accessible Infrastructure Reference Model (i.e. "IRM" or "TRM"), if updated more completely with current system data, can... c. ...help shed light on ways to mitigate risks and avoid future costs associated with NOT leveraging potentially-available shared services across the enterprise... 2. ....the following Marketing & Communications (Sales) Plan can be constructed: a. Create an easy-to-read "Consequence Model" that illustrates how adoption of a cloud capability (like elastic operational storage) can enable rapid and durable compliance with the mandate – using EA traceability. Traceability might be from the IRM to the ARM (that identifies reusable services invoking the elastic storage), and then to the PRM with performance measures (such as % utilization of purchased storage allocation) included in the OMB Exhibits; and b. Schedule a meeting with the Program Owners, timed during their Acquisition Strategy meetings in response to the mandate, to use the "Consequence Model" for advising them to organize a rapid and relevant RFI solicitation for this cloud capability (regarding alternatives for sourcing elastic operational storage); and c. Schedule a series of short "Discovery" meetings with the system architecture leads (as agreed by the Program Owners), to further populate/validate the "As-Is" models and frame the "To Be" models (via scenarios), to better inform the RFI, obtain the best feedback from the vendor community, and provide potential value for and avoid impact to all other programs and systems. --end example -- Note that communications with the intended audience should take a page out of the standard "Search Engine Optimization" (SEO) playbook, using keywords and phrases relating to "value" and "outcome" vs. "compliance" and "output". Searches in email boxes, internal and external search engines for phrases like "cost avoidance strategies", "mission performance metrics" and "innovation funding" should yield messages and content from the EA team. This targeted, informed, practical sales approach should result in additional buy-in and participation, additional EA information contribution and model validation, development of more SMEs and quick "proof points" (with real-life testing) to bolster the case for EA. The proof point here is a successful, timely procurement that satisfies not only the external mandate and external oversight review, but also meets internal EA compliance/conformance goals and therefore is more transparently useful across the community. In short, if sold effectively, the EA will perform and be recognized. EA won’t therefore be used only for compliance, but also (according to a validated, stated purpose) to directly influence decisions and outcomes.

  • Google and Bing Map APIs Compared

    - by SGWellens
    At one of the local golf courses I frequent, there is an open grass field next to the course. It is about eight acres in size and mowed regularly. It is permissible to hit golf balls there—you bring and shag our own balls. My golf colleagues and I spend hours there practicing, chatting and in general just wasting time. One of the guys brings Ginger, the amazing, incredible, wonder dog. Ginger is a Portuguese Pointer. She chases squirrels, begs for snacks and supervises us closely to make sure we don't misbehave.     Anyway, I decided to make a dedicated web page to measure distances on the field in yards using online mapping services. I started with Google maps and then did the same application with Bing maps. It is a good way to become familiar with the APIs. Here are images of the final two maps: Google:  Bing:   To start with online mapping services, you need to visit the respective websites and get a developers key. I pared the code down to the minimum to make it easier to compare the APIs. Google maps required this CSS (or it wouldn't work): <style type="text/css">     html     {         height: 100%;     }       body     {         height: 100%;         margin: 0;         padding: 0;     } Here is how the map scripts are included.

Note: When creating the Bing map, use the developer Key for the credentials property. I immediately place two markers/pins on the map which is simpler that creating them on the fly with mouse clicks (as I first tried). The markers/pins are draggable and I capture the DragEnd event to calculate and display the distance in yards and draw a line when the user finishes dragging. Here is the code to place a marker: Google: // ---- PlaceMarker ------------------------------------   function PlaceMarker(location) {     var marker = new google.maps.Marker(         {             position: location,             map: gTheMap,             draggable: true         });     marker.addListener('dragend', DragEnd);     return marker; }   Bing: // ---- PlaceMarker ------------------------------------   function PlaceMarker(location) {     var marker = new Microsoft.Maps.Pushpin(location,     {         draggable : true     });     Microsoft.Maps.Events.addHandler(marker, 'dragend', DragEnd);     gTheMap.entities.push(marker);     return marker; } Here is the code than runs when the user stops dragging a marker: Google: // ---- DragEnd -------------------------------------------   var gLine = null;   function DragEnd(Event) {     var meters = google.maps.geometry.spherical.computeDistanceBetween(marker1.position, marker2.position);     var yards = meters * 1.0936133;     $("#message").text(yards.toFixed(1) + ' yards');    // draw a line connecting the points     var Endpoints = [marker1.position, marker2.position];       if (gLine == null)     {         gLine = new google.maps.Polyline({             path: Endpoints,             strokeColor: "#FFFF00",             strokeOpacity: 1.0,             strokeWeight: 2,             map: gTheMap         });     }     else        gLine.setPath(Endpoints); } Bing: // ---- DragEnd -------------------------------------------   var gLine = null;   function DragEnd(Args) {    var Distance =  CalculateDistance(marker1._location, marker2._location);      $("#message").text(Distance.toFixed(1) + ' yards');       // draw a line connecting the points    var Endpoints = [marker1._location, marker2._location];           if (gLine == null)    {        gLine = new Microsoft.Maps.Polyline(Endpoints,            {                strokeColor: new Microsoft.Maps.Color(0xFF, 0xFF, 0xFF, 0),  // aRGB                strokeThickness : 2            });          gTheMap.entities.push(gLine);    }    else        gLine.setLocations(Endpoints);  }   Note: I couldn't find a function to calculate the distance between points in the Bing API, so I wrote my own (CalculateDistance). If you want to see the source for it, you can pick it off the web page. Note: I was able to verify the accuracy of the measurements by using the golf hole next to the field. I put a pin/marker on the center of the green, and then by zooming in, I was able to see the 150 markers on the fairway and put the other pin/marker on one of them. Final Notes: All in all, the APIs are very similar. Both made it easy to accomplish a lot with a minimum amount of code. In one aerial view, there are leaves on the tree, in the other, the trees are bare. I don't know which service has the newer data.

  • jQuery featured content slider

    - by azz0r
    Hello, I have a content area that loops through divs and shows there content. I'm having trouble making it display the initial content, unfortunately it waits 5000 milliseconds before triggering the very first content area to display. Anyone spot an easy way to make it display the initial area, then slide to the next area and do them at 5000 milliseconds. JS Model.FeatureBar = { current:0, items:{}, init: function init(options){ var me = this; me.triggers = [] me.slides = [] this.container = jQuery('#features'); jQuery('.feature').each(function(i){ me.triggers[i] = {url: jQuery(this).children('.feature-title a').href, title: jQuery(this).children('.feature-title'),description:jQuery(this).children('.feature-description')} me.slides[i] = {image: jQuery(this).children('.feature-image')} }); for(var i in this.slides){ this.slides[i].image.hide(); this.triggers[i].description.hide(); } setInterval(function(){Model.FeatureBar.next()},5000); }, next: function next(){ var i = (this.current+1 < this.triggers.length) ? this.current+1 : 0; this.goToItem(i); }, previous: function previous(){ var i = (this.current-1 > 1) ? this.current-1 : this.triggers.length; this.goToItem(i); }, goToItem: function goToItem(i){ if(!this.slides[i]) throw 'Slide out of range'; this.triggers[this.current].description.slideUp(); this.triggers[i].description.slideDown(); this.slides[this.current].image.hide(); this.slides[i].image.show(); this.current = i; }, } html <div id="features"> <div class="feature current"> <div class="movie-cover"> <a href="/police/movie"><img title="" alt="" src="/design/images/four-oh-four.png"></a> </div> <div class="feature-image" style="display: none;"> <img src="/design/images/four-oh-four.png"> </div> <h2 class="feature-title"><a href="/police/movie">Police</a></h2> <p class="feature-description" style="overflow: hidden; display: block; height: 50.8604px; margin-top: 0px; margin-bottom: 0px; padding-top: 0px; padding-bottom: 0px;">DESCRIPTION</p> </div> <div class="feature"> <div class="movie-cover"> <a href="/rude/movie"><img title="" alt="" src="/design/images/four-oh-four.png"></a> </div> <div class="feature-image" style="display: none;"> <img src="/design/images/four-oh-four.png"> </div> <h2 class="feature-title"><a href="/rude/movie">Rude</a></h2> <p class="feature-description" style="overflow: hidden; display: block; height: 18.3475px; margin-top: 0px; margin-bottom: 0px; padding-top: 0px; padding-bottom: 0px;">DESCRIPTION</p> </div> <div class="feature"> <div class="movie-cover"> <a href="/brits/movie"><img title="" alt="" src="/design/images/four-oh-four.png"></a> </div> <div class="feature-image" style="display: block;"> <img src="/design/images/four-oh-four.png"> </div> <h2 class="feature-title"><a href="/brits/movie">Brits</a></h2> <p class="feature-description" style="overflow: hidden; display: block; height: 40.1549px; margin-top: 0px; margin-bottom: 0px; padding-top: 0px; padding-bottom: 0px;">DESCRIPTION</p> </div> <div class="feature"> <div class="movie-cover"> <a href="/indie/movie"><img title="" alt="" src="/design/images/four-oh-four.png"></a> </div> <div class="feature-image" style="display: none;"> <img src="/design/images/four-oh-four.png"> </div> <h2 class="feature-title"><a href="/indie/movie">Indie</a></h2> <p class="feature-description" style="overflow: hidden; display: block; height: 42.4247px; margin-top: 0px; margin-bottom: 0px; padding-top: 0px; padding-bottom: 0px;">DESCRIPTION</p> </div>

  • Google and Bing Map APIs Compared

    - by SGWellens
    At one of the local golf courses I frequent, there is an open grass field next to the course. It is about eight acres in size and mowed regularly. It is permissible to hit golf balls there—you bring and shag our own balls. My golf colleagues and I spend hours there practicing, chatting and in general just wasting time. One of the guys brings Ginger, the amazing, incredible, wonder dog. Ginger is a Hungarian Vizlas (or Hungarian pointer). She chases squirrels, begs for snacks and supervises us closely to make sure we don't misbehave. Anyway, I decided to make a dedicated web page to measure distances on the field in yards using online mapping services. I started with Google maps and then did the same application with Bing maps. It is a good way to become familiar with the APIs. Here are images of the final two maps: Google:  Bing:   To start with online mapping services, you need to visit the respective websites and get a developers key. I pared the code down to the minimum to make it easier to compare the APIs. Google maps required this CSS (or it wouldn't work): <style type="text/css">     html     {         height: 100%;     }       body     {         height: 100%;         margin: 0;         padding: 0;     } Here is how the map scripts are included. Google requires the developer Key when loading the JavaScript, Bing requires it when the map object is created: Google: <script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=XXXXXXX&libraries=geometry&sensor=false" > </script> Bing: <script  type="text/javascript" src="http://ecn.dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=7.0"> </script> Note: I use jQuery to manipulate the DOM elements which may be overkill, but I may add more stuff to this application and I didn't want to have to add it later. Plus, I really like jQuery. Here is how the maps are created: Common Code (the same for both Google and Bing Maps):     <script type="text/javascript">         var gTheMap;         var gMarker1;         var gMarker2;           $(document).ready(DocLoaded);           function DocLoaded()         {             // golf course coordinates             var StartLat = 44.924254;             var StartLng = -93.366859;               // what element to display the map in             var mapdiv = $("#map_div")[0];   Google:         // where on earth the map should display         var StartPoint = new google.maps.LatLng(StartLat, StartLng);           // create the map         gTheMap = new google.maps.Map(mapdiv,             {                 center: StartPoint,                 zoom: 18,                 mapTypeId: google.maps.MapTypeId.SATELLITE             });           // place two markers         marker1 = PlaceMarker(new google.maps.LatLng(StartLat, StartLng + .0001));         marker2 = PlaceMarker(new google.maps.LatLng(StartLat, StartLng - .0001));           DragEnd(null);     } Bing:         // where on earth the map should display         var StartPoint = new  Microsoft.Maps.Location(StartLat, StartLng);           // create the map         gTheMap = new Microsoft.Maps.Map(mapdiv,             {                 credentials: 'XXXXXXXXXXXXXXXXXXX',                 center: StartPoint,                 zoom: 18,                 mapTypeId: Microsoft.Maps.MapTypeId.aerial             });           // place two markers         marker1 = PlaceMarker(new Microsoft.Maps.Location(StartLat, StartLng + .0001));         marker2 = PlaceMarker(new Microsoft.Maps.Location(StartLat, StartLng - .0001));           DragEnd(null);     } Note: In the Bing documentation, mapTypeId: was missing from the list of options even though the sample code included it.

  • Image not loading onto JPanel?

    - by None None
    I have been trying to figure out how to add an image to a JPanel as a background, but still have complete control over the placing of JButtons, JLabels, and etc. This is one method I found, but it is crashing and not loading the image or buttons. Here is the code: import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.JButton; import java.awt.BorderLayout; import java.awt.FlowLayout; import java.awt.GridLayout; public class PanelDemo extends JFrame { private static final long serialVersionUID = 1L; private JButton btn1 = new JButton("EASY"); private JButton btn2 = new JButton("MEDIUM"); private JButton btn3 = new JButton("HARD"); private JButton btn4 = new JButton("High Score"); public PanelDemo() { super("Image Panel Demo"); JPanel panel = new ImagePanel( new FlowLayout(FlowLayout.CENTER, 50, 180)); JPanel panelbtn = new JPanel(new GridLayout(4, 1)); btn1.setBackground(new java.awt.Color(0, 0, 0)); btn1.setFont(new java.awt.Font("Showcard Gothic", 1, 24)); btn1.setForeground(new java.awt.Color(0, 255, 102)); btn2.setBackground(new java.awt.Color(0, 0, 0)); btn2.setFont(new java.awt.Font("Showcard Gothic", 1, 24)); btn2.setForeground(new java.awt.Color(0, 255, 102)); btn3.setBackground(new java.awt.Color(0, 0, 0)); btn3.setFont(new java.awt.Font("Showcard Gothic", 1, 24)); btn3.setForeground(new java.awt.Color(0, 255, 102)); btn4.setBackground(new java.awt.Color(0, 0, 0)); btn4.setFont(new java.awt.Font("Showcard Gothic", 1, 24)); btn4.setForeground(new java.awt.Color(0, 255, 102)); panel.add(panelbtn); panelbtn.add(btn1); panelbtn.add(btn2); panelbtn.add(btn3); panelbtn.add(btn4); add(panel, BorderLayout.CENTER); setSize(640, 480); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } public static void main(String... args) { new PanelDemo().setVisible(true); } } ImagePanel.java import java.awt.Graphics; import java.awt.Image; import java.awt.LayoutManager; import javax.swing.ImageIcon; import javax.swing.JPanel; public class ImagePanel extends JPanel { private static final long serialVersionUID = 1L; String imageFile = "/rsc/img/background.jpg"; public ImagePanel() { super(); } public ImagePanel(String image) { super(); this.imageFile = image; } public ImagePanel(LayoutManager layout) { super(layout); } public void paintComponent(Graphics g) { ImageIcon imageicon = new ImageIcon(getClass().getResource(imageFile)); Image image = imageicon.getImage(); super.paintComponent(g); if (image != null) g.drawImage(image, 0, 0, getWidth(), getHeight(), this); } } Error: Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at javax.swing.ImageIcon.<init>(Unknown Source) at ImagePanel.paintComponent(ImagePanel.java:27) at javax.swing.JComponent.paint(Unknown Source) at javax.swing.JComponent.paintChildren(Unknown Source) at javax.swing.JComponent.paint(Unknown Source) at javax.swing.JComponent.paintChildren(Unknown Source) at javax.swing.JComponent.paint(Unknown Source) at javax.swing.JLayeredPane.paint(Unknown Source) at javax.swing.JComponent.paintChildren(Unknown Source) at javax.swing.JComponent.paintToOffscreen(Unknown Source) at javax.swing.RepaintManager$PaintManager.paintDoubleBuffered(Unknown Source) at javax.swing.RepaintManager$PaintManager.paint(Unknown Source) at javax.swing.RepaintManager.paint(Unknown Source) at javax.swing.JComponent.paint(Unknown Source) at java.awt.GraphicsCallback$PaintCallback.run(Unknown Source) at sun.awt.SunGraphicsCallback.runOneComponent(Unknown Source) at sun.awt.SunGraphicsCallback.runComponents(Unknown Source) at java.awt.Container.paint(Unknown Source) at java.awt.Window.paint(Unknown Source) at javax.swing.RepaintManager$3.run(Unknown Source) at javax.swing.RepaintManager$3.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.security.ProtectionDomain$1.doIntersectionPrivilege(Unknown Source) at javax.swing.RepaintManager.paintDirtyRegions(Unknown Source) at javax.swing.RepaintManager.paintDirtyRegions(Unknown Source) at javax.swing.RepaintManager.prePaintDirtyRegions(Unknown Source) at javax.swing.RepaintManager.access$1000(Unknown Source) at javax.swing.RepaintManager$ProcessingRunnable.run(Unknown Source) at java.awt.event.InvocationEvent.dispatch(Unknown Source) at java.awt.EventQueue.dispatchEventImpl(Unknown Source) at java.awt.EventQueue.access$200(Unknown Source) at java.awt.EventQueue$3.run(Unknown Source) at java.awt.EventQueue$3.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.security.ProtectionDomain$1.doIntersectionPrivilege(Unknown Source) at java.awt.EventQueue.dispatchEvent(Unknown Source) at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source) Also, if anyone knows of a better way to put a background image on a JPanel, pease do tell.

  • Many-to-one relation exception due to closed session after loading

    - by Nick Thissen
    Hi, I am using NHibernate (version 1.2.1) for the first time so I wrote a simple test application (an ASP.NET project) that uses it. In my database I have two tables: Persons and Categories. Each person gets one category, seems easy enough. | Persons | | Categories | |--------------| |--------------| | Id (PK) | | Id (PK) | | Firstname | | CategoryName | | Lastname | | CreatedTime | | CategoryId | | UpdatedTime | | CreatedTime | | Deleted | | UpdatedTime | | Deleted | The Id, CreatedTime, UpdatedTime and Deleted attributes are a convention I use in all my tables, so I have tried to bring this fact into an additional abstraction layer. I have a project DatabaseFramework which has three important classes: Entity: an abstract class that defines these four properties. All 'entity objects' (in this case Person and Category) must inherit Entity. IEntityManager: a generic interface (type parameter as Entity) that defines methods like Load, Insert, Update, etc. NHibernateEntityManager: an implementation of this interface using NHibernate to do the loading, saving, etc. Now, the Person and Category classes are straightforward, they just define the attributes of the tables of course (keeping in mind that four of them are in the base Entity class). Since the Persons table is related to the Categories table via the CategoryId attribute, the Person class has a Category property that holds the related category. However, in my webpage, I will also need the name of this category (CategoryName), for databinding purposes for example. So I created an additional property CategoryName that returns the CategoryName property of the current Category property, or an empty string if the Category is null: Namespace Database Public Class Person Inherits DatabaseFramework.Entity Public Overridable Property Firstname As String Public Overridable Property Lastname As String Public Overridable Property Category As Category Public Overridable ReadOnly Property CategoryName As String Get Return If(Me.Category Is Nothing, _ String.Empty, _ Me.Category.CategoryName) End Get End Property End Class End Namespace I am mapping the Person class using this mapping file. The many-to-one relation was suggested by Yads in another thread: <id name="Id" column="Id" type="int" unsaved-value="0"> <generator class="identity" /> </id> <property name="CreatedTime" type="DateTime" not-null="true" /> <property name="UpdatedTime" type="DateTime" not-null="true" /> <property name="Deleted" type="Boolean" not-null="true" /> <property name="Firstname" type="String" /> <property name="Lastname" type="String" /> <many-to-one name="Category" column="CategoryId" class="NHibernateWebTest.Database.Category, NHibernateWebTest" /> (I can't get it to show the root node, this forum hides it, I don't know how to escape the html-like tags...) The final important detail is the Load method of the NHibernateEntityManager implementation. (This is in C# as it's in a different project, sorry about that). I simply open a new ISession (ISessionFactory.OpenSession) in the GetSession method and then use that to fill an EntityCollection(Of TEntity) which is just a collection inheriting System.Collections.ObjectModel.Collection(Of T). public virtual EntityCollection< TEntity Load() { using (ISession session = this.GetSession()) { var entities = session .CreateCriteria(typeof (TEntity)) .Add(Expression.Eq("Deleted", false)) .List< TEntity (); return new EntityCollection< TEntity (entities); } } (Again, I can't get it to format the code correctly, it hides the generic type parameters, probably because it reads the angled symbols as a HTML tag..? If you know how to let me do that, let me know!) Now, the idea of this Load method is that I get a fully functional collection of Persons, all their properties set to the correct values (including the Category property, and thus, the CategoryName property should return the correct name). However, it seems that is not the case. When I try to data-bind the result of this Load method to a GridView in ASP.NET, it tells me this: Property accessor 'CategoryName' on object 'NHibernateWebTest.Database.Person' threw the following exception:'Could not initialize proxy - the owning Session was closed.' The exception occurs on the DataBind method call here: public virtual void LoadGrid() { if (this.Grid == null) return; this.Grid.DataSource = this.Manager.Load(); this.Grid.DataBind(); } Well, of course the session is closed, I closed it via the using block. Isn't that the correct approach, should I keep the session open? And for how long? Can I close it after the DataBind method has been run? In each case, I'd really like my Load method to just return a functional collection of items. It seems to me that it is now only getting the Category when it is required (eg, when the GridView wants to read the CategoryName, which wants to read the Category property), but at that time the session is closed. Is that reasoning correct? How do I stop this behavior? Or shouldn't I? And what should I do otherwise? Thanks!
