• Visual Studio 2008: Can't connect to known good TFS 2010 beta 2

  - by p.campbell

  A freshly installed TFS 2010 Beta 2 is at http://serverX:8080/tfs. A Windows 7 developer machine with VS 2008 Pro SP1 and the VS2008 Team Explorer (no SP). The TFS 2008 Service Pack 1 didn't work for me - "None of the products that are addressed by this software update are installed on this computer." The developer machine is able to browse the TFS site at the above URL. The Issue is around trying to add the TFS server into the Team Explorer window in Visual Studio 2008. Here's a screenshot showing the error: unable to connect to this Team Foundation Server. Possible reasons for failure include: The Team Foundation Server name, port number or protocol is incorrect. The Team Foundation Server is offline. Password is expired or incorrect. The TFS server is up and running properly. Firewall ports are open, and is accessible via the browser on the dev machine!! larger image Question: how can you connect from VS 2008 Pro to a TFS 2010 Beta 2 server? Resolution Here's how I solved this problem: installed VS 2008 Team Explorer as above. re-install VS 2008 Service Pack 1 when adding a TFS server to Team Explorer, you MUST specify the URL as such: http://[tfsserver]:[port]/[vdir]/[projectCollection] in my case above, it was http://serverX:8080/tfs/AppDev-TestProject you cannot simply add the TFS server name and have VS look for all Project Collections on the server. TFS 2010 has a new URL (by default) and VS 2008 doesn't recognize how to gather that list.

• TypeError: Error #1009 - (Null reference error) With Flash.

  - by Wind Chimez

  I am not an expert in flash, but i do work with AS and tweak Flash projects , though not having deep expertise in it. Currently i need to revamp a flash website done by one another guy, and the code base given to me, upon execution is throwing the following error. "--- TypeError: Error #1009: Cannot access a property or method of a null object reference. at NewSite_fla::MainTimeline/__setProp_ContactOutP1_ContactOut_Contents_0() at NewSite_fla::MainTimeline/frame1() --" The structure of the project is like, it has the different sections split into different movie clips. There is no single main timeline, but click actions on different areas of seperate movie clips will take them between one another. All the AS logic of event handling are written inline in FLA , no seperate Document class exists. Preloader Movie clip is the first one getting loaded. As i understood the error is getting thrown initially itself, and it is not happening due to any Action script logic written inline, because it is throwing error even before hitting the first inline AS code. I am not able to figure Out what exactly it causing the problem, or where to resolve it. I really got stuck at this point. Any help will be great.I had not seen the particular solution i am looking for anywhere yet, though Error #1009 is common. I uploaded the fla, here ( http://tinyurl.com/249e95p ), for reference.It may not be working , since the included/refered video files and all are not there, but reviwing the action code/movie clips will be possible. Please let me know if somebody will be able to trace the issue exactly.

• Is MVC 2 client-side validation broken in Visual Studio 2010 RC?

  - by Will

  I can't seem to get client side validation working with the version of MVC released with Visual Studio 2010 RC. I've tried it with two projects -- one upgrade from 1.0, and one using the template that came with VS. I'd think the template version would work, but it doesn't. Added the following scripts: <script type="text/javascript" src="<%= Url.Content("~/Scripts/MicrosoftMvcValidation.js") %>"> </script> <script type="text/javascript" src="<%= Url.Content("~/Scripts/jquery.validate.js")%>"> </script> which are downloaded to the client correctly. Added the following to my form page: <% Html.EnableClientValidation(); %> <%--yes, am aware of the EndForm() bug! --%> <% using (Html.BeginForm()) { %> <%--snip --%> and I can see the client validation scripts have been added to the bottom of the form. But still client validation never happens. What is worse is that in my upgraded project, the client validation scripts are never output in the page! PLEASE NOTE: I am specifically asking about the version of MVC2 that came with VS2010 RC. Also, I do know how to google; please don't waste anybody's time searching and answering if you aren't familiar with this issue in the release candidate of Visual Studio. Thanks.

• Altering lazy-loaded object's private variables

  - by Kevin Pang

  I'm running into an issue with private setters when using NHibernate and lazy-loading. Let's say I have a class that looks like this: public class User { public int Foo {get; private set;} public IList<User> Friends {get; set;} public void SetFirstFriendsFoo() { // This line works in a unit test but does nothing during a live run with // a lazy-loaded Friends list Users(0).Foo = 1; } } The SetFirstFriendsFoo call works perfectly inside a unit test (as it should since objects of the same type can access each others private properties). However, when running live with a lazy-loaded Friends list, the SetFirstFriendsFoo call silently fails. I'm guessing the reason for this is because at run-time, the Users(0).Foo object is no longer of type User, but of a proxy class that inherits from User since the Friends list was lazy-loaded. My question is this: shouldn't this generate a run-time exception? You get compile-time exceptions if you try to access another class's private properties, but when you run into a situation like this is looks like the app just ignores you and continues along its way.

• Page_PreRender fires twice on first load in session

  - by awe

  I have an issue when I access the application, I notice that Page_PreRender is fired twice. This only happens the first time in a new session. It does not happen if I refresh the page, or on postbacks. I use .NET framework 3.5 and the built in ajax functionality. I think the problem is not related to img tag with empty src attribute as I have seen other posts has mentioned, because I see this in both FireFox and IE. The posts I saw about this stated that this was not a problem in IE. I have also searched and found no img tags with empty src in the generated page source, so it should not be this. I have also made a simple test page where I have included some of the functionality, and this does not happen. Here I have also tried to reproduce the empty src bug by including <img src="" /> on the page, but this does not trigger this problem. Have anyone any suggestions on what happens? Note: It is the entire page cycle that is firing twice, not just render.

• Catching 'Last Record' in Coldfusion for IE javascript bug

  - by Simon Hume

  I'm using ColdFusion to pull UK postcodes into an array for display on a Google Map. This happens dynamically from a SQL database, so the numbers can range from 1 to 100+ the script works great, however, in IE (groan) it decides to display one point way off line, over in California somewhere. I fixed this issue in a previous webapp, this was due to the comma between each array item still being present at the end. Works fine in Firefox, Safari etc, but not IE. But, that one was using a set 10 records, so was easy to fix. I just need a little if statement to wrap around my comma to hide it when it hits the last record. I can't seem to get it right. Any tips/suggestions? here is the line of code in question: var address = [<cfloop query="getApplicant"><cfif getApplicant.dbHomePostCode GT ""><cfoutput>'#getApplicant.dbHomePostCode#',</cfoutput></cfif> </cfloop>]; Hopefully someone can help with this rather simple request. I'm just having a bad day at the office!

• Does Android XML Layout's 'include' Tag Really Work?

  - by Eric Burke

  I am unable to override attributes when using <include> in my Android layout files. When I searched for bugs, I found Declined Issue 2863: "include tag is broken (overriding layout params never works)" Since Romain indicates this works in the test suites and his examples, I must be doing something wrong. My project is organized like this: res/layout buttons.xml res/layout-land receipt.xml res/layout-port receipt.xml The buttons.xml contains something like this: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal"> <Button .../> <Button .../> </LinearLayout> And the portrait and landscape receipt.xml files look something like: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical"> ... <!-- Overridden attributes never work. Nor do attributes like the red background, which is specified here. --> <include android:id="@+id/buttons_override" android:background="#ff0000" android:layout_width="fill_parent" layout="@layout/buttons"/> </LinearLayout> What am I missing?

• Calling PHP functions within HEREDOC strings

  - by Doug Kavendek

  In PHP, the HEREDOC string declarations are really useful for outputting a block of html. You can have it parse in variables just by prefixing them with $, but for more complicated syntax (like $var[2][3]), you have to put your expression inside {} braces. In PHP 5, it is possible to actually make function calls within {} braces inside a HEREDOC string, but you have to go through a bit of work. The function name itself has to be stored in a variable, and you have to call it like it is a dynamically-named function. For example: $fn = 'testfunction'; function testfunction() { return 'ok'; } $string = <<< heredoc plain text and now a function: {$fn()} heredoc; As you can see, this is a bit more messy than just: $string = <<< heredoc plain text and now a function: {testfunction()} heredoc; There are other ways besides the first code example, such as breaking out of the HEREDOC to call the function, or reversing the issue and doing something like: ?> <!-- directly outputting html and only breaking into php for the function --> plain text and now a function: <?PHP print testfunction(); ?> The latter has the disadvantage that the output is directly put into the output stream (unless I'm using output buffering), which might not be what I want. So, the essence of my question is: is there a more elegant way to approach this? Edit based on responses: It certainly does seem like some kind of template engine would make my life much easier, but it would require me basically invert my usual PHP style. Not that that's a bad thing, but it explains my inertia.. I'm up for figuring out ways to make life easier though, so I'm looking into templates now.

• Debugging unexpected error message - possible memory management problem?

  - by Ben Packard

  I am trying to debug an application that is throwing up strange (to my untutored eyed) errors. When I try to simply log the count of an array... NSLog(@"Array has %i items", [[self startingPlayers] count]); ...I sometimes get an error: -[NSCFString count]: unrecognized selector sent to instance 0x1002af600 or other times -[NSConcreteNotification count]: unrecognized selector sent to instance 0x1002af600 I am not sending 'count' to any NSString or NSNotification, and this line of code works fine normally. A Theory... Although the error varies, the crash happens at predictable times, immediately after I have run through some other code where I'm thinking I might have a memory management issue. Is it possible that the object reference is still pointing to something that is meant to be destroyed? Sorry if my terms are off, but perhaps it's expecting the array at the address it calls 'count' on, but finds another previous object that shouldn't still be there (eg an NSString)? Would this cause the problem? If so, what is the most efficient way to debug and find out what is that address? Most of my debugging up until now involves inserting NSLogs, so this would be a good opportunity to learn how to use the debugger.

• Java: Exception in thread main java.lang.NoClassDefFoundError

  - by cath

  I am trying to get the Red5 Flash Media Server working on my computer. I have installed it, but when I run the server I get this error Exception in thread "main" java.lang.NoClassDefFoundError: org/red5/server/Bootstrap Caused by: java.lang.ClassNotFoundException: org.red5.server.Bootstrap at java.net.URLClassLoader$1.run(URLClassLoader.java:217) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:205) at java.lang.ClassLoader.loadClass(ClassLoader.java:321) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:294) at java.lang.ClassLoader.loadClass(ClassLoader.java:266) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:334) Could not find the main class: org.red5.server.Bootstrap.

• Query on object id in VQL

  - by Banang

  I'm currently working with the versant object database (using jvi), and have a case where I need to query the database based on an object id. What I'm trying to achieve is something along the lines of Employee employee = new Employee("Mr. Pickles"); session.commit(); FundVQLQuery q = new FundVQLQuery(session, "select * from Employee employee where employee = $1"); q.bind(employee); q.execute(); However, I'm finding out the hard way (I get an EVJ_NOT_A_VALID_KEY_TYPE error thrown at me) that this is infact not the way to do it. Anyone got any experience in working with VQL? Your help is much apreciated! A small clarification: The problem is I'm running some performance tests on the database using the pole position framework, and one of the tests in that framework requires me to fetch an object from the database using either an object reference or a low level object id. Thus, I'm not allowed to reference specific fields in the employee object, but must perform the query on the object in its entirety. So, it's not allowed for me to go "select * from Employee e where e.id = 4", I need it to use the entire object. Accepted answer: Since there is some sort of lunacy magic built into SO that prevents me to mark an accepted answer after a bounty has run out, readers should know that the answer posted by Chris Holmes solves this issue. Readers are encouraged to up-vote his post to further signalize the correctness of his answer to any future readers of this thread.

• Text box creates gap when floated left in IE7

  - by Sixfoot Studio

  Hi, I've got a left rounded corner box - textbox - right rounded corner box which all make up part of a search box. All's well in FF, Chrome, IE8 but not IE7. I've checked it using the debug tool and and I have tried a number of options, none of which want to work at the moment, so I am hoping someone might know what this issue (bug) might be please? Here's a snippet of my code: <div class="roundBox4"> <img src="../App_Themes/MyChoice2010/Images/reality-box-top.gif" width="228" height="8" /><img src="../App_Themes/MyChoice2010/Images/reality-box-locate.gif" width="228" height="49" /> <asp:ContentPlaceHolder ID="Box4Content" runat="server"> </asp:ContentPlaceHolder> <div class="locateABroker"> <img src="../App_Themes/MyChoice2010/Images/locate-broker-left.gif" class="locateBrokerLeft" height="19" width="3" /><asp:TextBox ID="TextBox1" CssClass="locateBrokerCenter" runat="server"></asp:TextBox><img src="../App_Themes/MyChoice2010/Images/locate-broker-right.gif" height="19" width="3" class="locateBrokerRight" /> <a href="" class="locateBrokerSubmit">Submit</a><img src="../App_Themes/MyChoice2010/Images/box-arrow.gif" class="linkArrow" width="8" height="14" /> </div>

• GUI for generating XML

  - by Kenston

  Hello. Does anybody know of GUIs for generating XMLs? This means the user will not be presented with an IDE with support for XML for him to type XML codes. This would be helpful for non-technical people using the system. I know this sounds easy, given many libraries that can help in generating XMLs. The issue here is that the schema is really that flexible rather than being straightforward like representing books in a library with their properties. Imagine HTML, where we can create font tags inside a body, a table, a div, or nested even within itself. The solution is a WYSIWYG application that allows user to generate html codes (XML). However, that is good for XML applied in webpages since they involve visual aspect and design. My application of XML would focus on representing some conceptual and computational definitions, much like sql-like syntax, but more than that. I'm actually after the approach or previous works done or tried, although having a library/working framework for that would be better. Btw, I'm using Java for this project. Currently, I'm just thinking of presenting element tags where user will be able to drag and drop them and nest them with each other. And perhaps, assist them through a forms in inputing values for XML attributes. I'm still hoping if there are better ideas from the community. Thank you.

• Completely bizarre Firefox CSS bug

  - by Jason

  I've been doing front end development for a long time, and I have NEVER come across a bug like this before... Save the following HTML to a file and view it in Firefox (mine is 3.6.3): <html xmlns="http://www.w3.org/1999/xhtml"> <head> <style type="text/css"> body { font-family: Helvetica, Sans-Serif;} h2 {font-weight: normal;} </style> </head> <body> <h2>Some normal text <strong>some bold text</strong> weird huh?</h2> </body> </html> If you don't want to give it a shot the output is like your cat walked across your keyboard while character map was turned on, except in the strong tags. I feel like this may be a font issue? When I get rid of font-weight: normal it goes back to normal, but I don't want everything to be bolded in my h2... Anyone have any ideas? More importantly, is anyone able to reproduce this?? Thanks.

• compiling and running java on windows

  - by artur grzesiak

  I thought the task should be fairly easy, but my understanding of javac and java in general is rather poor. I am using Windows8 and would like to compile a single file.java that makes use of other classes. I successfully (at least without any warnings) compiled my file by calling: javac -cp relative_path_to_needed_classes relative_path_to_file_java\file.java Now if I want to run the result of compilation (file.class) by calling: java -cp relative_path_to_needed_classes relative_path_to_file_java\file I get: Error: Could not find or load main class relative_path_to_file_java\file I was trying a lot of combination to modify the -cp (eg. by adding .\;relative_path_to_file;) but still the closest where I get is: Exception in thread "main" java.lang.NoClassDefFoundError : relative_path_to_file\file (wrong name: file) The file from (wrong name: file) is the name of the file and the name of the public class within the file. I was reading a lot on SO and other sources but could not figure out what is wrong. Btw. as a result of compilation some other classes were created: file$1.class file$name1.class file$name2.class (where name1 and name2 are names of private classes within file.java) My questions are: What is (the most) probably source of my error / what am I doing wrong? What is the purpose of file$1.class? What is the minimum I should specify in -cp? May encoding play any role? Do every java class have to reside in a package? (rather not directly related to my issue) Do order of paths specified in -cp play any role in runtime?

• AJAX Submit to PHP still loading page after preventDefault()

  - by dannyburrows

  I have a webpage that I am using .ajax to send variables to a php script. The php page is loading into the browser as if I was navigating to it. The script is loading the data correctly, so my issue is stopping the navigation and keeping the user on the original page. The code for my form is here: echo "<form method='post' action='addTask.php' id='myform'>\n"; echo "<input name='addtask' id='addtask' maxlength='64'/><br/>\n"; echo "<input type='submit' name='submit' id='submit' value='Add Task'/>\n"; echo "</form>\n"; The code for my jquery is here: $(function(){ $('#myform').submit(function(e){ e.stopPropagation(); $.ajax({ url: 'addTask.php', type: 'POST', data: {}, success: alert("Success") }); }); }); I have tried: e.preventDefault(), e.stopPropagation() and return false. Any help is appreciated. $("#submit").click(function(e){ e.preventDefault(); $.ajax({ type: "POST", url: "addtask.php", data: { } }) .done(function() { alert( "success" ); }) .fail(function() { alert( "error" ); }); and $(function(){ $('#myform').submit(function(e){ e.preventDefault(); $.ajax({ url: 'addTask.php', type: 'POST', data: {}, success: function(){alert("Success")} }); }); });

• iPod touch debugging: Error on install/run only if app exists on device already?

  - by Ben

  Hi all, I am using an iPod to test an app. The device is all set up with the right provisioning profiles, etc-- that's not really the issue. But every time I start the app from Xcode on the device, I get the "A signed resource has been added, modified, or deleted." error from the Organizer window. Wait, I know, you think it's a provisioning profile problem. But here's the kicker: if I just delete the app from the iPod (using the main screen) and try again, it works fine. I only get this error when the app is already installed. The other kicker is that this behavior doesn't happen on an iPhone that I have for occasional testing-- on that device, I can start/restart/restart indefinitely. But using the iPod, my compile-run-test cycle is annoyingly slow since I have to manually delete the app each time. Any ideas? I'm using Xcode 3.2.2 (prerelease) FWIW. The iPod has stock OS 3.1.2 on it. Thanks!

• How do you implement a good profanity filter?

  - by Ben Throop

  Many of us need to deal with user input, search queries, and situations where the input text can potentially contain profanity or undesirable language. Oftentimes this needs to be filtered out. Where can one find a good list of swear words in various languages and dialects? Are there APIs available to sources that contain good lists? Or maybe an API that simply says "yes this is clean" or "no this is dirty" with some parameters? What are some good methods for catching folks trying to trick the system, like a$$, azz, or a55? Bonus points if you offer solutions for PHP. :) Edit: Response to answers that say simply avoid the programmatic issue: I think there is a place for this kind of filter when, for instance, a user can use public image search to find pictures that get added to a sensitive community pool. If they can search for "penis", then they will likely get many pictures of, yep. If we don't want pictures of that, then preventing the word as a search term is a good gatekeeper, though admittedly not a foolproof method. Getting the list of words in the first place is the real question. So I'm really referring to a way to figure out of a single token is dirty or not and then simply disallow it. I'd not bother preventing a sentiment like the totally hilarious "long necked giraffe" reference. Nothing you can do there. :)

• JBoss: What does the warning EJBTHREE-1246 from the InterceptorRegistry mean?

  - by Simon Lehmann

  I am currently developing an EJB 3.0 based application on the JBoss AS 5.0.0.GA and just recently the following warning showed up in the server log: 09:50:19,735 WARN [InterceptorsFactory] EJBTHREE-1246: Do not use InterceptorsFactory with a ManagedObjectAdvisor, InterceptorRegistry should be used via the bean container 09:50:19,735 WARN [InterceptorsFactory] EJBTHREE-1246: Do not use InterceptorsFactory with a ManagedObjectAdvisor, InterceptorRegistry should be used via the bean container 09:50:19,735 WARN [InterceptorRegistry] applicable interceptors is non-existent for ... ... The warnings are generated as soon as an EJB (a stateless session bean) is injected into a backing bean of my JSF web-application. The beans do work without problems though, but I still would like to know where that warning comes from and what I can do to avoid it. I have already searched a bit around, but haven't found a good answer (some say, bean developers do not have to worry, but its a warning, so I'd like to have a better solution): http://www.jboss.com/index.html?module=bb&op=viewtopic&t=147292 http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4180366 http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4140136 JBoss JIRA Issue about the warning (Not that helpful in my opinion) So has anyone an explanation what causes the warning (in terms of a bean developer, not application server developer) and what to do to avoid it? Update: I've just upgraded JBoss to 5.0.1.GA (Download, Release-Notes) but unfortunatly the warning still appears.

• Images in database vs file system

  - by Jesse

  We have a project coming up where we will be building a whole backend CMS system that will power our entire extranet and intranet with one package. The question I have been trying to find an answer to is which is better: storing images in the database (SQL Server 2005) so we may have integrity, single replication plan, etc OR storing on the file system? One issue we have is that we have multiple servers load balanced that require to have the same data at all times. As of now we have SQL replication taking care of that but file replication seems to be a little tougher. Another concern we have is that we would like to have multiple resolutions of the same image, we are not sure if creating and storing each version on the file system would be best or maybe dynamically pulling and creating the resolution image we would like upon request. Our concerns are the with the following: Data integrity Data replication Multiple resolutions Speed of database vs file system Overhead load of database vs file system Data management and backup Does anyone have a similar situation or have any input on what would be recommended? Thanks in advance for the help!

• Dimension Mismatch MatLab; cant figure out why it is mismatching

  - by Abid

  I think it may be a syntax issue, here is the code. load ([ 'C:\Users\Abid\Desktop\Inquiry Runs\dtS' ]) dtS((dtS==0))=nan; for j=2:9; maxS=max(dtS(j,:)); minS=min(dtS(j,:)); maxval(j,:)=dtS((dtS>(maxS-.1*maxS))); minval(j,:)=dtS((dtS<(minS+.1*minS))); avmax(j)=mean(maxval(j,:)); avmin(j)=mean(minval(j,:)); avs(j,:)=[avmax(j) avmin(j)] end So I know the the row matrices are different sizes every loop. For example maxval(j,:) will change depending one row it is looking through for certain values. I did this manually and I see that on the first loop the matrices are size (1,1), however, if I set the loop to run for only j=2, the row length is 13. Usually if a matrix is changing size on the loop, I only get a warning, but this time I think it is due to a reason I don't understand.

• jquery png fix on hidden div and jquerybrowser question

  - by Jared

  Hello, I have some code that if Javascript is available, it will remove a GIF image and replace it with a PNG image. The PNG is display:none and the GIF is visible. Since IE6- browsers can't load PNG, I have loaded the jquery PNG fix. But it only seems to work if the image is already visible. The other issue is I am trying to get the jquery.browser function to apply to less than version 6, and I am not having much luck. <script type="text/javascript"> $(document).ready(function(){ $("#gif").hide(); jQuery.each(jQuery.browser, function(i, val) { if($.browser.msie && jQuery.browser.version <="6"){ $("#png").show(); $('.png').pngFix() }else{ $("#png").fadeIn("slow"); } }); }); </script> HTML <img class="png" id="png" src="images/main_elements/one-2-flush-it-campus-challenge.png" style="display:none;" /> <img id="gif" src="images/main_elements/one-2-flush-it-campus-challenge.gif"/>

• Zend Sessions problem with IE8

  - by Emil

  I'm running a Zend Framework powered website and it seems to have serious problems with sessions. I have a 5 step process where I save the form data in the session between the steps and then save it into the database on the last step. When we built the site sometimes the session just went away and forced us to restart. Now it seems to work again but recently we discovered an issue with Internet Explorer 8. It fails between step 2 - 3 and forgets the session. It works fine in IE6, IE7, FF, Chrome, Safari and even in my mobile web browser (SE P1). We're storing our sessions in the database and if I deactivate the session db handler it works. What's the difference between using the database and not using it for sessions? Do I loose something if I switch back? Bootstrap: /* Start session */ $saveHandler = new Zend_Session_SaveHandler_DbTable(array( 'name' => 'sessions', 'primary' => 'id', 'modifiedColumn' => 'modified', 'dataColumn' => 'data', 'lifetimeColumn' => 'lifetime' )); Zend_Session::rememberMe((int) $config->session->lifetime); $saveHandler->setLifetime((int) $config->session->lifetime) ->setOverrideLifetime(true); Zend_Session::setSaveHandler($saveHandler); Zend_Session::start(); and in my step controller $session = new Zend_Session_Namespace('wizard'); Then I'm just working with $session saving data in a stdClass in $session.

• Why should I use Entity Framework over Linq2SQL ...

  - by Refracted Paladin

  To be clear, I am not asking for a side by side comparision which has already been asked Ad Nauseum here on SO. I am also Not asking if Linq2Sql is dead as I don't care. What I am asking is this.... I am building internal apps only for a non-profit organization. I am the only developer on staff. We ALWAYS use SQL Server as our Database backend. I design and build the Databases as well. I have used L2S successfully a couple of times already. Taking all this into consideration can someone offer me a compelling reason to use EF instead of L2S? I was at Code Camp this weekend and after an hour long demonstration on EF, all of which I could have done in L2S, I asked this same question. The speakers answer was, "L2S is dead..." Very well then! NOT! (see here) I understand EF is what MS WANTS us to use in the future(see here) and that it offers many more customization options. What I can't figure out is if any of that should, or does, matter for me in this environment. One particular issue we have here is that I inherited the Core App which was built on 4 different SQL Data bases. L2S has great difficulty with this but when I asked the aforementioned speaker if EF would help me in this regard he said "No!"
