  • Generating All Permutations of Character Combinations when # of arrays and length of each array are

    - by Jay
    Hi everyone, I'm not sure how to ask my question in a succinct way, so I'll start with examples and expand from there. I am working with VBA, but I think this problem is non language specific and would only require a bright mind that can provide a pseudo code framework. Thanks in advance for the help! Example: I have 3 Character Arrays Like So: Arr_1 = [X,Y,Z] Arr_2 = [A,B] Arr_3 = [1,2,3,4] I would like to generate ALL possible permutations of the character arrays like so: XA1 XA2 XA3 XA4 XB1 XB2 XB3 XB4 YA1 YA2 . . . ZB3 ZB4 This can be easily solved using 3 while loops or for loops. My question is how do I solve for this if the # of arrays is unknown and the length of each array is unknown? So as an example with 4 character arrays: Arr_1 = [X,Y,Z] Arr_2 = [A,B] Arr_3 = [1,2,3,4] Arr_4 = [a,b] I would need to generate: XA1a XA1b XA2a XA2b XA3a XA3b XA4a XA4b . . . ZB4a ZB4b So the Generalized Example would be: Arr_1 = [...] Arr_2 = [...] Arr_3 = [...] . . . Arr_x = [...] Is there a way to structure a function that will generate an unknown number of loops and loop through the length of each array to generate the permutations? Or maybe there's a better way to think about the problem? Thanks Everyone!

  • PHPUnit and autoloaders: Determining whether code is running in test-scope?

    - by pinkgothic
    Premise I know that writing code to act differently when a test is run is hilariously bad practise, but I may've actually come across a scenario in which it may be necessary. Specifically, I'm trying to test a very specific wrapper for HTML Purifier in the Zend framework - a View Helper, to be exact. The HTML Purifier autoloader is necessary because it uses a different logic to the autoloaders we otherwise have. Problem require()-ing the autoloader at the top of my View Helper class, gives me the following in test-scope: HTML Purifier autoloader registrar is not compatible with non-static object methods due to PHP Bug #44144; Please do not use HTMLPurifier.autoload.php (or any file that includes this file); instead, place the code: spl_autoload_register(array('HTMLPurifier_Bootstrap', 'autoload')) after your own autoloaders. Replacing the require() with spl_autoload_register(array('HTMLPurifier_Bootstrap', 'autoload')) as advertised means the test runs fine, but the View Helper dies a terrible death claiming: Zend_Log[3707]: ErrorController caught LogicException "Passed array does not specify an existing static method (class 'HTMLPurifier_Bootstrap' not found)" (Our test folder structure is slightly different to our Zend folder structure by necessity.) Question(s) After tinkering with it, I'm thinking I'll need to pick an autoloader-loading depending on whether things are in the test scope or not. Do I have another option to include HTMLPurifier's autoloading routine in both cases that I'm not seeing due to tunnel vision? If not, do I have to find a means to differentiate between test-environment and production-environment this with my own code (e.g. APPLICATION_ENV) - or does PHPUnit support this godawful hackery of mine natively by setting a constant that I could check whether its been defined(), or similar shenanigans? (My Google-fu here is weak! I'm probably just doing it wrong.)

  • Testing a wide variety of computers with a small company

    - by Tom the Junglist
    Hello everyone, I work for a small dotcom which will soon be launching a reasonably-complicated Windows program. We have uncovered a number of "WTF?" type scenarios that have turned up as the program has been passed around to the various not-technical-types that we've been unable to replicate. One of the biggest problems we're facing is that of testing: there are a total of three programmers -- only one working on this particular project, me -- no testers, and a handful of assorted other staff (sales, etc). We are also geographically isolated. The "testing lab" consists of a handful of VMWare and VPC images running sort-of fresh installs of Windows XP and Vista, which runs on my personal computer. The non-technical types try to be helpful when problems arise, we have trained them on how to most effectively report problems, and the software itself sports a wide array of diagnostic features, but since they aren't computer nerds like us their reporting is only so useful, and arranging remote control sessions to dig into the guts of their computers is time-consuming. I am looking for resources that allow us to amplify our testing abilities without having to put together an actual lab and hire beta testers. My boss mentioned rental VPS services and asked me to look in to them, however they are still largely very much self-service and I was wondering if there were any better ways. How have you, or any other companies in a similar situation handled this sort of thing? EDIT: According to the lingo, our goal here is to expand our systems testing capacity via an elastic computing platform such as Amazon EC2. At this point I am not sure suggestions of beefing up our unit/integration testing are going to help very much as we are consistently hitting walls at the systems testing phase. Has anyone attempted to do this kind of software testing on a cloud-type service like EC2? Tom

  • Returned JSON from Twitter and displaying tweets using FlexSlider

    - by Trey Copeland
    After sending a request to the Twitter API using geocode, I'm getting back a json response with a list of tweets. I then that into a php array using json_decode() and use a foreach loop to output what I need. I'm using flex slider to show the tweets in a vertical fashion after wrapping them in a list. So what I want is for it to only show 10 tweets at a time and scroll through them infinitely like an escalator. Here's my loop to output the tweets: foreach ($tweets["results"] as $result) { $str = preg_replace('/[^\00-\255]+/u', '', $result["text"]); echo '<ul class="slides">'; echo '<li><a href="http://twitter.com/' . $result["from_user"] . '"><img src=' . $result["profile_image_url"] . '></a>' . $str . '</li><br /><br />'; echo '</ul>'; } My jQuery looks like this as of right now as I'm trying to play around with things: $(window).load(function() { $('.flexslider').flexslider({ slideDirection: "vertical", start: function(slider) { //$('.flexslider .slides > li gt(10)').hide(); }, after: function(slider) { // current.sl } }); }); Non-Working demo here - http://macklabmedia.com/tweet/

  • Using PHP to display button with hyperlink or greyed out button if no URL in database

    - by Diane
    I've got a webpage that I'm working on where you click on a letter or category and it displays records matching that query from a database. One of the things I want to display is a hyperlinked button that says "Website" if the database record contains a URL in the 'URL' field, and if there is no value in that field, it will display a greyed out version of that button. I tried using an if...else statement, but was absolutely unable to get the syntax correct trying to get php to call up the 'URL' value in the middle of an "echo " So here's what I did: <?php if($row_rsmemalpha['URL'] != NULL) ?><a href="http://<?php echo ($row_rsmemalpha['URL']);?>"><target ="_blank"><img src="web_button_on.gif" alt="Website" border="0" height="18" width="103" /></target></a> <?php if($row_rsmemalpha['URL'] == NULL) echo "<img src=\"web_button_off.gif\" alt=\"No Website Available\" height=\"18\" width=\"103\" />"; ?> If there is a URL available it shows the button properly. But if there isn't a URL in the database it shows both buttons. I have spent a few days studying examples and tutorials on the web, but haven't found too much that helps. The buttons were completely non-functional when I started, so I'm pretty proud of getting this far with it! I've just run out of time and patience for more trial-and-error experimenting. Any help is appreciated... Diane

  • When *not* to use prepared statements?

    - by Ben Blank
    I'm re-engineering a PHP-driven web site which uses a minimal database. The original version used "pseudo-prepared-statements" (PHP functions which did quoting and parameter replacement) to prevent injection attacks and to separate database logic from page logic. It seemed natural to replace these ad-hoc functions with an object which uses PDO and real prepared statements, but after doing my reading on them, I'm not so sure. PDO still seems like a great idea, but one of the primary selling points of prepared statements is being able to reuse them… which I never will. Here's my setup: The statements are all trivially simple. Most are in the form SELECT foo,bar FROM baz WHERE quux = ? ORDER BY bar LIMIT 1. The most complex statement in the lot is simply three such selects joined together with UNION ALLs. Each page hit executes at most one statement and executes it only once. I'm in a hosted environment and therefore leery of slamming their servers by doing any "stress tests" personally. Given that using prepared statements will, at minimum, double the number of database round-trips I'm making, am I better off avoiding them? Can I use PDO::MYSQL_ATTR_DIRECT_QUERY to avoid the overhead of multiple database trips while retaining the benefit of parametrization and injection defense? Or do the binary calls used by the prepared statement API perform well enough compared to executing non-prepared queries that I shouldn't worry about it? EDIT: Thanks for all the good advice, folks. This is one where I wish I could mark more than one answer as "accepted" — lots of different perspectives. Ultimately, though, I have to give rick his due… without his answer I would have blissfully gone off and done the completely Wrong Thing even after following everyone's advice. :-) Emulated prepared statements it is!

  • Normalize whitespace and other plain-text formatting routines

    - by dreftymac
    Background: The language is JavaScript. The goal is to find a library or pre-existing code to do low-level plain-text formatting. I can write it myself, but why re-invent the wheel. The issue is: it is tough to determine if a "wheel" is out there, since any search for JavaScript libraries pulls up an ocean of HTML-centric stuff. I am not interested in HTML necessarily, just text. Example: I need a JavaScript function that changes this: BEFORE: nisi ut aliquip | ex ea commodo consequat duis |aute irure dolor in esse cillum dolore | eu fugiat nulla pariatur |excepteur sint occa in culpa qui | officia deserunt mollit anim id |est laborum ... into this ... AFTER: nisi ut aliquip | ex ea commodo consequat duis | aute irure dolor in esse cillum dolore | eu fugiat nulla pariatur | excepteur sint occa in culpa qui | officia deserunt mollit anim id | est laborum Question: Does it exist, a JavaScript library that is non-html-web-development-centric that has functions for normalizing spaces in delimited plain text, justifying and spacing plain text? Rationale: Investigating JavaScript for use in a programmer's text editor.

  • Where are the real risks in network security?

    - by Barry Brown
    Anytime a username/password authentication is used, the common wisdom is to protect the transport of that data using encryption (SSL, HTTPS, etc). But that leaves the end points potentially vulnerable. Realistically, which is at greater risk of intrusion? Transport layer: Compromised via wireless packet sniffing, malicious wiretapping, etc. Transport devices: Risks include ISPs and Internet backbone operators sniffing data. End-user device: Vulnerable to spyware, key loggers, shoulder surfing, and so forth. Remote server: Many uncontrollable vulnerabilities including malicious operators, break-ins resulting in stolen data, physically heisting servers, backups kept in insecure places, and much more. My gut reaction is that although the transport layer is relatively easy to protect via SSL, the risks in the other areas are much, much greater, especially at the end points. For example, at home my computer connects directly to my router; from there it goes straight to my ISPs routers and onto the Internet. I would estimate the risks at the transport level (both software and hardware) at low to non-existant. But what security does the server I'm connected to have? Have they been hacked into? Is the operator collecting usernames and passwords, knowing that most people use the same information at other websites? Likewise, has my computer been compromised by malware? Those seem like much greater risks. What do you think?

  • How to recursive rake? -- or suitable alternatives

    - by TerryP
    I want my projects top level Rakefile to build things using rakefiles deeper in the tree; i.e. the top level rakefile says how to build the project (big picture) and the lower level ones build a specific module (local picture). There is of course a shared set of configuration for the minute details of doing that whenever it can be shared between tasks: so it is mostly about keeping the descriptions of what needs building, as close to the sources being built. E.g. /Source/Module/code.foo and cie should be built using the instructions in /Source/Module/Rakefile; and /Rakefile understands the dependencies between modules. I don't care if it uses multiple rake processes (ala recursive make), or just creates separate build environments. Either way it should be self-containable enough to be processed by a queue: so that non-dependent modules could be built simultaneously. The problem is, how the heck do you actually do something like that with Rake!? I haven't been able to find anything meaningful on the Internet, nor in the documentation. I tried creating a new Rake::Application object and setting it up, but whatever methods I try invoking, only exceptions or "Don't know how to build task ':default'" errors get thrown. (Yes, all rakefiles have a :default). Obviously one could just execute 'rake' in a sub directory for a :modulename task, but that would ditch the options given to the top level; e.g. think of $(MAKE) and $(MAKEFLAGS). Anyone have a clue on how to properly do something like a recursive rake?

  • Elegantly handling constraint violations in EJB/JPA environment?

    - by hallidave
    I'm working with EJB and JPA on a Glassfish v3 app server. I have an Entity class where I'm forcing one of the fields to be unique with a @Column annotation. @Entity public class MyEntity implements Serializable { private String uniqueName; public MyEntity() { } @Column(unique = true, nullable = false) public String getUniqueName() { return uniqueName; } public void setUniqueName(String uniqueName) { this.uniqueName = uniqueName; } } When I try to persist an object with this field set to a non-unique value I get an exception (as expected) when the transaction managed by the EJB container commits. I have two problems I'd like to solve: 1) The exception I get is the unhelpful "javax.ejb.EJBException: Transaction aborted". If I recursively call getCause() enough times, I eventually reach the more useful "java.sql.SQLIntegrityConstraintViolationException", but this exception is part of the EclipseLink implementation and I'm not really comfortable relying on it's existence. Is there a better way to get detailed error information with JPA? 2) The EJB container insists on logging this error even though I catch it and handle it. Is there a better way to handle this error which will stop Glassfish from cluttering up my logs with useless exception information? Thanks.

  • Does NHibernate LINQ support ToLower() in Where() clauses?

    - by Daniel T.
    I have an entity and its mapping: public class Test { public virtual int Id { get; set; } public virtual string Name { get; set; } public virtual string Description { get; set; } } public class TestMap : EntityMap<Test> { public TestMap() { Id(x => x.Id); Map(x => x.Name); Map(x => x.Description); } } I'm trying to run a query on it (to grab it out of the database): var keyword = "test" // this is coming in from the user keyword = keyword.ToLower(); // convert it to all lower-case var results = session.Linq<Test> .Where(x => x.Name.ToLower().Contains(keyword)); results.Count(); // execute the query However, whenever I run this query, I get the following exception: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index Am I right when I say that, currently, Linq to NHibernate does not support ToLower()? And if so, is there an alternative that allows me to search for a string in the middle of another string that Linq to NHibernate is compatible with? For example, if the user searches for kap, I need it to match Kapiolani, Makapuu, and Lapkap.

  • Flex 3 - Issues with textArea "editable" property

    - by BS_C3
    Hello Community! I'm having issues with the property "editable" of textArea control. I have a component: OrderView.mxml and it's associated data class OrderViewData.as. Orderview.mxml is inside a viewStack to enable navigation from a component to another. In this particular case, OrderView.mxml is called by another component: SearchResult.mxml. I can thus navigate from SearchResult.mxml to OrderView.mxml, and back to SearchResult.mxml... OrderView.mxml has textArea and textInput control, that have to be editable or nonEditable depending on the property var isEditable:Boolean from OrderViewData.as. When the application is launched, isEditable = true. So, all textInput and textArea controls are editable the first time the user gets to OrderView.mxml. When the user clicks on the button order from OrderView.mxml, isEditable = false. When the user goes back to SearchResult.mxml, isEditable = true (again) -- Until here, everything works fine. The thing is: when the user goes back to OrderView.mxml for the second time (and beyond), even if the property isEditable = true, textArea controls are still non editable... But the textInput controls are editable! Here is some code for your comprehension: OrderView.mxml <mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml" backgroundColor="#F3EDEC"> <mx:TextArea id="contentTA" text="{OrderViewData.instance.contentTA}" enabled="{OrderViewData.instance.isEnabled}" width="100%" height="51" maxChars="18" styleName="ORTextInput" focusIn="if(OrderViewData.instance.isEditable) contentTA.setSelection(0, contentTA.length)"/> <mx:TextInput id="contentTI" text="{OrderViewData.instance.contentTI}" width="40" height="18" maxChars="4" styleName="ORTextInput" change="contentTI_change()" focusIn="if(OrderViewData.instance.isEditable) contentTI.setSelection(0, contentTI.length)" editable="{OrderViewData.instance.isEditable}"/> </mx:Canvas> Am I missing something? Thanks for any help you can provide. Regards. BS_C3

  • Why is it assumed that send may return with less than requested data transmitted on a blocking socke

    - by Ernelli
    The standard method to send data on a stream socket has always been to call send with a chunk of data to write, check the return value to see if all data was sent and then keep calling send again until the whole message has been accepted. For example this is a simple example of a common scheme: int send_all(int sock, unsigned char *buffer, int len) { int nsent; while(len 0) { nsent = send(sock, buffer, len, 0); if(nsent == -1) // error return -1; buffer += nsent; len -= nsent; } return 0; // ok, all data sent } Even the BSD manpage mentions that ...If no messages space is available at the socket to hold the message to be transmitted, then send() normally blocks... Which indicates that we should assume that send may return without sending all data. Now I find this rather broken but even W. Richard Stevens assumes this in his standard reference book about network programming, not in the beginning chapters, but the more advanced examples uses his own writen (write all data) function instead of calling write. Now I consider this still to be more or less broken, since if send is not able to transmit all data or accept the data in the underlying buffer and the socket is blocking, then send should block and return when the whole send request has been accepted. I mean, in the code example above, what will happen if send returns with less data sent is that it will be called right again with a new request. What has changed since last call? At max a few hundred CPU cycles have passed so the buffer is still full. If send now accepts the data why could'nt it accept it before? Otherwise we will end upp with an inefficient loop where we are trying to send data on a socket that cannot accept data and keep trying, or else? So it seems like the workaround, if needed, results in heavily inefficient code and in those circumstances blocking sockets should be avoided at all an non blocking sockets together with select should be used instead.

  • Android 2.1 fling gesture captured on textview but still a contextmenu opens

    - by hermo
    The following problem seems unique to 2.1, happens both on an emulator and on a nexus. The same example works fine on other platforms I've tested (1.5, 1.6 and 2.0 emulators). I've added created gestureListener as described in this post. The difference is that I've added the listener on a TextView which also has a contextMenu registered, i.e. sth like the following: onCreate(...) { ... // Layout contains a large TextView on which I want to add a context menu tv = findViewById(R.id.text_view); tv.registerForContextMenu(this); // create the gestureListener according above mentioned post. gestureListener = ... // set the listener on the text-view tv.setOnTouchListener(gestureListener); ... } When testing it, the correct gesture is recognized alright, but every other time it also causes the context menu to be opened. As the same example is working on non 2.1 platforms, I've got a feeling it is not my code that is the problem... Thankful for any suggestions.

  • Problem with cruise control and visual svn

    - by Andrew
    Hi Wonder if anyone can help, I am experiencing a strange issue with my configuration of cruisecontrol.net and visual svn. I am setting the current ccnet.config <sourcecontrol type="svn"> <trunkUrl>https://bladerunner.azullo.local:8443/svn/application/trunk</trunkUrl> <executable>C:\Program Files (x86)\VisualSVN Server\bin\svn.exe</executable> <username>test</username> <password>test</password> <workingDirectory>D:\Development\Build\application\</workingDirectory> </sourcecontrol> <publishers> <xmllogger/> </publishers> <modificationDelaySeconds>10</modificationDelaySeconds> </project> When I run this I expect it to go to https://bladerunner.azullo.local:8443/svn/application/trunk, however i get the following ThoughtWorks.CruiseControl.Core.CruiseControlException: Source control operation failed: svn: OPTIONS of 'http://bladerunner.azullo.local:8080/svn/application/trunk': could not connect to server (http://bladerunner.azullo.local:8080) .

It goes to the correct url. I dont understand this behaviour. I have configured visual svn with a certificate using Active directory Certificate Services, if this was the problem I would expect it to show an error regarding the certificate instead of changing the url. I have cleared our state etc Any Ideas

  • Ideas for a rudimentary software licensing implementation

    - by Ross
    I'm trying to decide how to implement a very basic licensing solution for some software I wrote. The software will run on my (hypothetical) clients' machines, with the idea being that the software will immediately quit (with a friendly message) if the client is running it on greater-than-n machines (n being the number of licenses they have purchased). Additionally, the clients are non-tech-savvy to the point where "basic" is good enough. Here is my current design, but given that I have little to no experience in the topic, I wanted to ask SO before I started any development on it: A remote server hosts a MySQL database with a table containing two columns: client-key and license quantity The client-side application connects to the MySQL database on startup, offering it's client-key that I've put into a properties file packaged into the distribution (I would create a new distribution for each new client) Chances are, I'll need a second table to store validation history, so that with some short logic, the software can decide if it can be run on a given machine (maybe a sliding window of n machines using the software per 24 hours) If the software cannot establish a connection to the MySQL database, or decides that it's over the n allowed machines per day, it closes The connection info for the remote server hosting the MySQL database should be hard-coded into the app? (That sounds like a bad idea, but otherwise they could point it to some other always-validates-to-success server) I think that about covers my initial design. The intent being that while it certainly isn't full-proof, I think I've made it at least somewhat difficult to create an easily-sharable cracking solution. Also, I can easily adjust the license amount for a given client/key pair. I gotta figure this has been done a million times before, so tell me about a better solution that's just as simple to implement and provides the same (low) amount of security. In the event that external libraries are used, I prefer Java, as that's what the software has been written in.

  • Umlaute from JSP-page are misinterpreted

    - by Karin
    I'm getting Input from a JSP page, that can contain Umlaute. (e.g. Ä,Ö,Ü,ä,ö,ü,ß). Whenever an Umlaut is entered in the Input field an incorrect value gets passed on. e.g. If an "ä" (UTF-8:U+00E4) gets entered in the input field, the String that is extracted from the argument is "ä" (UTF-8: U+00C3 and U+00A4) It seems to me as if the UTF-8 hex encoding (which is c3 a4 for an "ä") gets used for the conversion. How can I retrieved the correct value? Here are snippets from the current implementation The JSP-page passes the input value "pk" on to the processing logic: <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> ... <input type="text" name="<%=pk.toString()%>" value="<%=value%>" size="70"/> <button type="submit" title="Edit" value='Save' onclick="action.value='doSave';pk.value='<%=pk.toString()%>'"><img src="icons/run.png"/>Save</button> The value gets retrieved from args and converted to a string: UUID pk = UUID.fromString(args.get("pk")); //$NON-NLS-1$ String value = args.get(pk.toString()); Note: Umlaute that are saved in the Database get displayed correctly on the page.

  • SqlLite/Fluent NHibernate integration test harness initialization not repeatable after large data se

    - by Mark Rogers
    In one of my main data integration test harnesses I create and use Fluent NHibernate's SingleConnectionSessionSourceForSQLiteInMemoryTesting, to get a fresh session for each test. After each test, I close the connection, session, and session factory, and throw out the nested StructureMap container they came from. This works for almost any simple data integration test I can think, including ones that utilize Fluent NHib's PersistenceSpecification object. When I test the application's lengthy database bootstrapping process, which creates and saves thousands of domain objects, I start seeing issues. It's not that the setup and tear down fails, in fact, the test successfully bootstraps the in-memory database as the application would bootstrap the real database in the production environment. The problem occurs when the database bootstrapping occurs a second time on a new in-memory database, with a new session and session factory. The error is: NHibernate.StaleStateException : Unexpected row count: 0; expected: 1 The row count is indeed Unexpected, the row that the application under test is looking for should be in the session. You see, it's not that any data from the last integration test is sticking around, it's that for some reason the session just stops working mid-database-boostrap. And I've looked everywhere for a place I might be holding on to an old session and I can't find one. I've searched through the code for static singleton objects, but there are none anywhere near the code in question. I have a couple StructureMap InstanceScope singleton's but they are getting thrown out with each nested container that is lost after every test teardown. I've tried every possible variation on disposing and closing every object involved with each test teardown and it still fails on this lengthy database bootstrap. But non-bootstrap related database tests appear to work fine. I'm starting to run out of options and may have to surrender lengthy database integration tests in favor of WatiN-based acceptance tests. Can anyone give me any clue about how I can figure out why some of my SingleConnectionSessionSourceForSQLiteInMemoryTesting aren't repeatable? Any advice at all, about how to make an NHibernate SqlLite database integration test harness repeatable?

  • What's the compelling reason to upgrade to Visual Studio 2010 from VS2008?

    - by Cheeso
    Are there new features in Visual Studio 2010 that are must-haves? If so, which ones? For me, the big draws for VS2008 as compared to VS2005 were LINQ, .NET Framework multitargeting, WCF (REST + Syndication), and general devenv.exe reliability. Granted, some of these features are framework things, and not tool things. For the purposes of this discussion, I'm willing to combine them into one bucket. What is the list of must-have features for VS2010 versus VS2008? Are there any? I am particularly interested in C#. Update: I know how to google, so I can get the official list from Microsoft. I guess what I really wanted was, the assessment from people using it, as to which things are really notable. Microsoft went on for 3 pages about 2008/3.5 features, and many people sort of boiled it down to LINQ, and a few other things. What is that short list for VS2010? Summary so far, what people think is cool or compelling: Visual Studio engine multi-monitor support new extensibility model based on WPF, prettier and more usable new TFS stuff, incl automated test tools parallel debugging .NET Framework parallel extensions for .NET C# 4.0 generic variance optional and named params easier interop with non-managed environments, like COM or Javascript VB 10.0 collection and array literals / initializers automatic properties anonymous methods / statement lambdas I read up on these at Zander's blog. He described these and other features. Nobody on this list said anything about: Visual Studio engine F# support Javascript code-completion JQuery is now included UML better Sharepoint capabilities C++ moves to msbuild project files

  • What is the 'page lifecycle' of an ASP.NET MVC page, compared to ASP.NET WebForms?

    - by Simon
    What is the 'page lifecycle' of an ASP.NET MVC page, compared to ASP.NET WebForms? I'm tryin to better understand this 'simple' question in order to determine whether or not existing pages I have in a (very) simple site can be easily converted from ASP.NET WebForms. Either a 'conversion' of the process below, or an alternative lifecycle would be what I'm looking for. What I'm currently doing: (yes i know that anyone capable of answering my question already knows all this -- i'm just tryin to get a comparison of the 'lifecycle' so i thought i'd start by filling in what we already all know) Rendering the page: I have a master page which contains my basic template I have content pages that give me named regions from the master page into which I put content. In an event handler for each content page I load data from the database (mostly read-only). I bind this data to ASP.NET controls representing grids, dropdowns or repeaters. This data all 'lives' inside the HTML generated. Some of it gets into ViewState (but I wont go into that too much!) I set properties or bind data to certain items like Image or TextBox controls on the page. The page gets sent to the client rendered as non-reusable HTML. I try to avoid using ViewState other than what the page needs as a minimum. Client side (not using ASP.NET AJAX): I may use JQuery and some nasty tricks to find controls on the page and perform operations on them. If the user selects from a dropdown -- a postback is generated which triggers a C# event in my codebehind. This event may go to the database, but whatever it does a completely newly generated HTML page ends up getting sent back to the client. I may use Page.Session to store key value pairs I need to reuse later So with MVC how does this 'lifecycle' change?

  • nhibernate not taking mappings from assembly

    - by cvista
    Hi I'm using fnh and castle nhib facility. I followed the advice from mike hadlow here: http://mikehadlow.blogspot.com/2009/01/integrating-fluent-nhibernate-and.html here is my FluentNHibernateConfigurationBuilder: public Configuration GetConfiguration(IConfiguration facilityConfiguration) { var defaultConfigurationBuilder = new DefaultConfigurationBuilder(); var configuration = defaultConfigurationBuilder.GetConfiguration(facilityConfiguration); configuration.AddMappingsFromAssembly(typeof(User).Assembly); return configuration; } i know the facility is picking it up as i can break inside that method and it steps through. however, when it's done, non of the mappings are created and i get the following error when i try to save an entity: No persister for: IsItGd.Model.Entities.User here is my user class: //simple model of web user public class User { public virtual int Id { get; set; } public virtual string FullName { get; set; } } and here is the mapping: public class UserMap : ClassMap<User> { public UserMap() { Id(x=>x.Id); Map(x=>x.FullName); } } i really can't see what the problem is. the strange thing is - is that if i use automapping it picks everything up - but i don't want to use automapping as i can't do certain things in that scenario. any clues? w://

  • How to access application.xml file of an EAR deployed to IBM WebSphere 6.1

    - by Matt1776
    I am deploying an EAR file to the IBM WebSpehre server 6.1 - I want to be able to access the EAR application name which is stored in the deployment file under 'display-name'. Looking through stack overflow posts on related subjects, I've been able to gather that this is possible via the Java MBean API - or IBM's WAS API - Problem is I cannot find a place where these API lists are summarized, i.e. cannot figure out which one to begin looking at. I could hardcode the WAS install location and find the file by looking in the 'installedApps' directory, but this is not dynamic. Does anyone have any experience working with these APIs? Any other way to dynamically find the deployed EAR's display name? EDIT - I should add that the reason I would like this information is to dynamically load our properties files - that are named by the following convention "EARAppName.properties" - so you see there IS a reasonable 'rationale' behind desiring this information in my application EDIT 2 - I should also note that this app will always be deployed on a WAS - but in the case that it isnt, a generic non-proprietary solution would be preferred, but not necessary at this moment. EDIT 3 - What I want to accomplish: Is there a way to dynamically find the deployed EAR's display name from within the application code?

  • Purge complete Python installation on OS X

    - by Konrad Rudolph
    I’m working on a recently-upgraded OS X Snow Leopard and MacPorts and I’m running into problems at every corner. The first problem is the sheer number of installed Python versions: altogether, there are four: 2.5, 2.6 and 3.0 in /Library/Frameworks/Python.framework 2.6 in /opt/local/Library/Frameworks/Python.framework/ (MacPorts installation) So there are at least two useless/redundant versions: 2.5 and the redundant 2.6. Additionally, the pre-installed Python is giving me severe problems because some of the pre-installed libraries (in particular, scipy, numpy and matplotlib) don’t work properly. I am sorely tempted to purge the complete /Library/Frameworks/Python.framework path, as well as the MacPorts Python installation. After that, I’ll start from a clean slate by installing a properly configured Python, e.g. that from Enthought. Am I running headlong into trouble? Or is this a sane undertaking? (In particular, I need a working Python in the next few days and if I end up with a non-working Python this would be a catastrophe of medium proportions. On the other hand, some features I need from matplotlib aren’t working now.)

  • al32utf8 in oracle and SQL Server and DB2 pulling data

    - by Bob
    I have a non-utf8 oracle database running on 11.1.0.7. We need to support greek characters. So we have two options: use nvarchar, nclob fields for those fields that need greek (it is not all fields). We have tested this and gotten it to work with java coding. convert Oracle to AL32UTF8 database. I am not asking how to do this. I got this from the Oracle Site/Oracle Support. I know what is involved, lossy data, etc, increasing the size of the database. My question is we have users to our system that connect to our database with database links but work on SQL Server and IBM DB2 databases. I do not have access to those databases and I do not have experience with them. If they are not in UTF-8 databases what happens when they pull UTF8 data? I would assume that English/Ascii characters are fine and the greek will end up as junk data. I also ran Oracle Character set scanner (oracle command line utility you use to get info about the affects of a character set conversion). It says that my database will crease in sizez by about 20%. Does this have an affect on users with 3rd party databases? These are customers of our data and there is a limit to how much access I can have to them to run tests. Any information you have would be welcome.
