  • Mixing Silverlight-Specific System.Xml.Linq dll with Non-Silverlight System.Xml.Linq dll

    - by programatique
    I have a Logic layer that references Silverlight's System.Xml.Linq dll and a GUI that is in WPF (hence using the non-Silverlight System.Xml.Linq dll). When I attempt to pass an XElement from GUI project to a method in the Logic project, I am getting (basically) "XElement is not of type XElement" errors. To complicate matter, I am unable to edit the Logic layer project. The Non-Silverlight DLL is at: C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\v3.5\System.Xml.Linq.dll THe Silverlight DLL is at: C:\Program Files (x86)\Microsoft SDKs\Silverlight\v3.0\Libraries\Client\System.Xml.Linq.dll I am new to C# but I'm fairly sure my issue is that I am referencing different DLL's to access the System.Xml.Linq namespace. I attempted to replace my non-Silverlight System.Xml.Linq.dll with the Silverlight's System.Xml.Linq.dll, but received assembly errors. Is there any way to resolve this short of scrapping my WPF GUI project and creating a Silverlight project?

  • Adding binary checkbox values to MySQL database using PHP

    - by klyv
    I'm new to PHP, and I am creating a basic CMS using PHP and MySQL. I'm struggling to get the checkbox information from my HTML page across into the database. How can I make the values to appear as binary 0 or 1 values? The HTML document is written as follows: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title>Create your news page</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> </head> <body> <fieldset> <legend>Checked components will show in the page</legend> <form method="POST" action="http://*********.php"> <span class="label">Header</span> <input type="checkbox" name="header" value="HEADER"> <br> <span class="label">Footer</span> <input type="checkbox" name="footer" value="FOOTER"> <hr> <span class="label">Local news</span> <input type="checkbox" name="local" value="LOCALNEWS"> <br> <span class="label">National news</span> <input type="checkbox" name="national" value="NATIONALNEWS"> <br> <span class="label">International news</span> <input type="checkbox" name="international" value="INTERNATIONALNEWS"> <p> <input type="submit"> </form> </fieldset> </body> </html> And the PHP document is written as follows: <?php $user="user_***"; $password="*********"; $database="dbxyz"; mysql_connect("localhost", $user, $password); mysql_select_db($database, $db_handle); mysql_select_db("dbxyz"); if(isset($_POST['layout'])) { foreach($_POST['layout'] as $value { $insert="INSERT INTO layout (header, footer, local, national, international) VALUES ('$value')"; mysql_query($insert); } } ?>

  • Strategy for Offline/Online data synchronization

    - by Adi
    My requirement is I have server J2EE web application and client J2EE web application. Sometimes client can go offline. When client comes online he should be able to synchronize changes to and fro. Also I should be able to control which rows/tables need to be synchronized based on some filters/rules. Is there any existing Java frameworks for doing it? If I need to implement on my own, what are the different strategies that you can suggest? One solution in my mind is maintaining sql logs and executing same statements at other side during synchronization. Do you see any problems with this strategy?

  • struts2 trim all string obtained from forms

    - by aelkin
    Hi All, I develop web application using struts2. I want to improve getting string from forms. For this need trim all string and if obtained string is empty then set null to field. For this, I created StringConverter. public class StringConverter extends StrutsTypeConverter { @Override public Object convertFromString(Map context, String[] strings, Class toClass) { if (strings == null || strings.length == 0) { return null; } String result = strings[0]; if (result == null) { return null; } result = result.trim(); if (result.isEmpty()) { return null; } return result; } @Override public String convertToString(Map context, Object object) { if (object != null && object instanceof String) { return object.toString(); } return null; } } Next, I added row to xwork-conversion.properties java.lang.String=com.mypackage.StringConverter Thats all. But I did not get the desired result. convertToString() method is called when jsp build form, but convertFromString() doesn't invoke. What I do wrong? How can I get the same behaviour using another way? Please, not offer solutions such as: remove the value of such form elements using javascript. create util method which will make it using reflection. Then call it for each form bean. Thanks in advance, Alexey.

  • How Do I Restrict Repository Access via WebSVN?

    - by kaybenleroll
    I have multiple subversion repositories which are served up through Apache 2.2 and WebDAV. They are all located in a central place, and I used this debian-administration.org article as the basis (I dropped the use of the database authentication for a simple htpasswd file though). Since then, I have also started using WebSVN. My issue is that not all users on the system should be able to access the different repositories, and the default setup of WebSVN is to allow anyone who can authenticate. According to the WebSVN documentation, the best way around this is to use subversion's path access system, so I looked to create this, using the AuthzSVNAccessFile directive. When I do this though, I keep getting "403 Forbidden" messages. My files look like the following: I have default policy settings in a file: <Location /svn/> DAV svn SVNParentPath /var/lib/svn/repository Order deny,allow Deny from all </Location> Each repository gets a policy file like below: <Location /svn/sysadmin/> Include /var/lib/svn/conf/default_auth.conf AuthName "Repository for sysadmin" require user joebloggs jimsmith mickmurphy </Location> The default_auth.conf file contains this: SVNParentPath /var/lib/svn/repository AuthType basic AuthUserFile /var/lib/svn/conf/.dav_svn.passwd AuthzSVNAccessFile /var/lib/svn/conf/svnaccess.conf I am not fully sure why I need the second SVNParentPath in default_auth.conf, but I just added that today as I was getting error messages as a result of adding the AuthzSVNAccessFile directive. With a totally permissive access file [/] joebloggs = rw the system worked fine (and was essentially unchanged), but as I soon as I start trying to add any kind of restrictions such as [sysadmin:/] joebloggs = rw instead, I get the 'Permission denied' errors again. The log file entries are: [Thu May 28 10:40:17 2009] [error] [client 89.100.219.180] Access denied: 'joebloggs' GET websvn:/ [Thu May 28 10:40:20 2009] [error] [client 89.100.219.180] Access denied: 'joebloggs' GET svn:/sysadmin What do I need to do to get this to work? Have configured apache wrong, or is my understanding of the svnaccess.conf file incorrect? If I am going about this the wrong way, I have no particular attachment to my overall approach, so feel free to offer alternatives as well. UPDATE (20090528-1600): I attempted to implement this answer, but I still cannot get it to work properly. I know most of the configuration is correct, as I have added [/] joebloggs = rw at the start and 'joebloggs' then has all the correct access. When I try to go repository-specific though, doing something like [/] joebloggs = rw [sysadmin:/] mickmurphy = rw then I got a permission denied error for mickmurphy (joebloggs still works), with an error similar to what I already had previously [Thu May 28 10:40:20 2009] [error] [client 89.100.219.180] Access denied: 'mickmurphy' GET svn:/sysadmin Also, I forgot to explain previously that all my repositories are underneath /var/lib/svn/repository UPDATE (20090529-1245): Still no luck getting this to work, but all the signs seem to be pointing to the issue being with path-access control in subversion not working properly. My assumption is that I have not conf

  • Rip and Convert DVD’s to an ISO Image

    - by Mysticgeek
    If you own a lot of DVD’s, you might want to convert them to an ISO image for backup and easily playing them on your media center. Today we take a look at ripping your discs using DVDFab, then using ImgBurn to create an ISO image of the ripped DVD files. Rip DVD with DVDFab6 DVDFab will remove copy protection and rip the DVD files for free. Other components in the suite require you to purchase a license after the 30 day trial, but you’ll still be able to rip DVD’s after the trial. Install DVDFab by accepting the defaults (link below)…a system restart is required to complete the install process. The first time you run it, a welcome screen is displayed. If you don’t want to see it again check the box Do not show again, then Start DVDFab.  Pop the DVD in your drive and click Next. Now select your region and check Do not show again, then OK. It will then open the DVD and begin to scan it. Under DVD to DVD you can select either Full Disc or Main Movie depending on what you want to rip. If you want to burn the DVD to a disc after it’s created select the Full Disc option. Now click the Start button to begin the ripping process. After the ripping process has completed, you’ll get a message telling you it’s waiting for you to put in a blank DVD. Since we aren’t burning the disc, just cancel the message. Click Finish and close out of DVDFab or just minimize it if you’re going to keep using it to rip another DVD. By default the temporary directory is in My Documents \ DVDFab \ Temp…however you can change it in settings. If you go to the Temp directory you’ll see the DVD files listed there… Convert Files to ISO with ImgBurn Now that we have the files ripped from the DVD, we need to convert them to an ISO image using ImgBurn (link below). Open it up and from the main menu click on Create image file from files/folders. Click on the folder icon to browse to the location of the ripped DVD files. Browse to the DVDFab temp directory and the VIDEO_TS folder for the source and click Ok. Then choose a destination directory, give the ISO a name, and click Save. In this case we ripped the Unbreakable DVD, so named it that.   So now in ImgBurn you have the source being the ripped DVD files, and the destination for the ISO…then click the Build button. If you don’t create a volume label, ImgBurn is kind enough to create on for you. If everything looks correct, click Ok. Now wait while ImgBurn goes through the process of converting the ripped DVD files to an ISO image. The process has successfully completed. The ISO image of the DVD will be in the output directory you selected earlier. Now you can burn the ISO image to a blank DVD or store it on an external hard drive for safe keeping. When you’re done, you’ll probably want to go into the temp DVDFab folder and delete the VOB and other files in the Video_TS folder as they will take up a lot of space on your hard drive.   Conclusion Although this method requires two programs to make an ISO out of a DVD, it’s extremely quick. When burning DVD’s of various lengths, it took less than 30 minutes to get the final ISO. Now, you’ll have your DVD movies backed up in case something were to happen to the discs and are no longer playable. If you use Windows Media Center to watch your movies, check out our article on how to automatically mount and view ISO files in Windows 7 Media Center. With DVDFab, you get a 30 day fully functional trial for all of its features. You’ll still be able rip DVD’s even after the 30 day trial has ended. The more we’ve been using DVDFab, the more impressed we are with its capabilities, so after the 30 day trial you should consider purchasing a license. We will have a full review of the of it to share with you soon.  Download DVDFab Download ImgBurn Similar Articles Productive Geek Tips How To Rip DVDs with VLCCalculate with Qalculate on LinuxConvert a Row to a Column in Excel the Easy WayEnjoy Quick & Easy Unit Conversion with Convert for WindowsConvert Older Excel Documents to Excel 2007 Format TouchFreeze Alternative in AutoHotkey The Icy Undertow Desktop Windows Home Server – Backup to LAN The Clear & Clean Desktop Use This Bookmarklet to Easily Get Albums Use AutoHotkey to Assign a Hotkey to a Specific Window Latest Software Reviews Tinyhacker Random Tips Revo Uninstaller Pro Registry Mechanic 9 for Windows PC Tools Internet Security Suite 2010 PCmover Professional Beware Hover Kitties Test Drive Mobile Phones Online With TryPhone Ben & Jerry’s Free Cone Day, 3/23/10 New Stinger from McAfee Helps Remove ‘FakeAlert’ Threats Google Apps Marketplace: Tools & Services For Google Apps Users Get News Quick and Precise With Newser

  • How do I do a postback to a CGI service

    - by TheLearner
    I am building a C# client for a CGI service (not sure what its called exactly). It accepts a bunch of XML and spits out a response. I have tested it straight in Firefox and it works (see below). Now I am not sure how to do this in C# code though?

  • How to let parent control know that its child got focus?

    - by Axarydax
    Hi there, imagine that I have a Form with 9 controls (TabbedStuffControl) in a 3x3 tile, and these controls contain TabControls containing another control (StuffControl) with ListBoxes and TextBoxes. I'd like to know a proper way to let TabbedStuffControl that its child has received a focus? e.g. user clicks into a textbox of StuffControl or drags something to listbox of StuffControl. Eventually the Form should know which TabbedStuffControl is active Do I need to hook up GotFocus event of TextBoxes and ListBoxes and TabControls, then dispatch another event to finally let Form know who got focus? I think that there should be a simpler way - that somehow TabbedStuffControl knows that its child got focus, so there would be only one place in code that I'll hook up. Thanks.

  • How to export Oracle statistics

    - by A_M
    Hi, I am writing some new SQL queries and want to check the query plans that the Oracle query optimiser would come up with in production. My development database doesn't have anything like the data volumes of the production database. How can I export database statistics from a production database and re-import them into a development database? I don't have access to the production database, so I can't simply generate explain plans on production without going through a third party hosting organisation. This is painful. So I want a local database which is in some way representative of production on which I can try out different things. Also, this is for a legacy application. I'd like to "improve" the schema, by adding appropriate indexes. constraints, etc. I need to do this in my development database first, before rolling out to test and production. If I add an index and re-generate statistics in development, then the statistics will be generated around the development data volumes, which makes it difficult to assess the impact my changes on production. Does anyone have any tips on how to deal with this? Or is it just a case of fixing unexpected behaviour once we've discovered it on production? I do have a staging database with production volumes, but again I have to go through a third party to run queries against this, which is painful. So I'm looking for ways to cut out the middle man as much as possible. All this is using Oracle 9i. Thanks.

  • jTabbedPane opens different tab on loading

    - by Santeron
    Hey mates, First of all I'm using netbeans as my IDE and I don't know if this is causing it. When I run my program (even if I have build it and run the .jar) I think it selects the tab that was previously selected (before quiting). So if for example I close the app with the third tab selected, it starts up with that selected again. Is there a known solution for this? The selectedIndex property on the jTabbedPane is set to 0. Shouldn't this property be the default onLoad value? Thx in advance, Jimmy PS. BTW for some reason it didn't submit my question in Opera (?)

  • how to dynamically break NHibernation cascade

    - by Joe Black
    The NHibernate cascade setting in the entity mapping is static. Is there anyway to dynamically disable the "cascade" setting in code to avoid expensive cascade operation in NHiberate during a bulky data transaction? We do not want to use stored procedures or native SQL because we need to have the entity changes captured by NHibernate (audit).

  • How to round-off hours based on Minutes(hours+0 if min<30, hours+1 otherwise) ?

    - by infant programmer
    I need to round-off the hours based on the minutes in a DateTime variable. The condition is: if minutes are less than 30, then minutes must be set to zero and no changes to hours, else if minutes =30, then hours must be set to hours+1 and minutes are again set to zero. Seconds are ignored. example: 11/08/2008 04:30:49 should become 11/08/2008 05:00:00 and 11/08/2008 04:29:49 should become 11/08/2008 04:00:00 I have written code which works perfectly fine, but just wanted to know a better method if could be written and also would appreciate alternative method(s). string date1 = "11/08/2008 04:30:49"; DateTime startTime; DateTime.TryParseExact(date1, "MM/dd/yyyy HH:mm:ss", null, System.Globalization.DateTimeStyles.None, out startTime); if (Convert.ToInt32((startTime.Minute.ToString())) > 29) { startTime = DateTime.Parse(string.Format("{0}/{1}/{2} {3}:{4}:{5}", startTime.Month.ToString(), startTime.Day.ToString(), startTime.Year.ToString(), startTime.Hour.ToString(), "00", "00")); startTime = startTime.Add(TimeSpan.Parse("01:00:00")); Console.WriteLine("startTime is :: {0}", startTime.ToString("MM/dd/yyyy HH:mm:ss")); } else { startTime = DateTime.Parse(string.Format("{0}/{1}/{2} {3}:{4}:{5}", startTime.Month.ToString(), startTime.Day.ToString(), startTime.Year.ToString(), startTime.Hour.ToString(), "00", "00")); Console.WriteLine("startTime is :: {0}", startTime.ToString("MM/dd/yyyy HH:mm:ss")); }
