• Implement LINQ to Entities unsupported method

  - by Dan

  Hi! LINQ to Entities has many LINQ methods marked as "Unsupported" (http://msdn.microsoft.com/en-us/library/bb738550.aspx). Is any way to implement some of these methods by hands? Or I should wait next release of EF? I'm especially needing this method: IQueryable<TResult> Select<TSource, TResult>(this IQueryable<TSource> source, Expression<Func<TSource, int, TResult>> selector) Thanks

• WPF: How to make Contextmenu select and forget?

  - by Kave

  I have a Contextmenu with a ListBox inside. Whenever I right click my control and select a value from my contextmenu the last selected value stays marked and I can't select that value again. The idea is, that I may select the same value within the COntextmenu in order to turn a property on or off. Should be quite basic, what am I missing? Many Thanks,

• Geben for emacs on Ubuntu 10.04

  - by jhedstrom

  I've had geben running perfectly on previous versions of Ubuntu. After the upgrade, and installing the latest version of geben (0.26), it only half works. Specifically, when in context mode, local variables are always marked as undefined. Has anybody successfully gotten geben up and running under Ubuntu 10.04, or is this a bug in geben (I've reported it as one, but thought I'd check here just in case there is a workaround). geben 0.26 xdebug 2.0.5 emacs 23.1.1 5.3.2-1ubuntu4.1 Thanks!

• Check if webbased CertEnroll will succeed

  - by Tim Mahy

  Hi all, for a project we will be doing webbased certificate enrollment, in Vista / Win7 combination with IE this gives some problems if the user does not import the root certificate first and then changes a lot of default IE settings (Enable ActiveX not marked safe for scripting etc....). I was wondering if any of you ever created a test VB or Javascript to test that all the settings are OK. So it can be used by the user before he starts the enrollment process.... greetings, Tim

  Take a look that the following code snippet: A a = null try { a = new A(); } finally { a.foo(); // What happens at this point? } Suppose A's constructor throws a runtime exception.

• factory girl - know when an attribute is overridden in factory

  - by carlos

  Is there any way to determine if attributes are overridden in a factory and adjust the behavior of the factory based on those overrides? The evaluator passed into the callbacks contains a __override_names__ method. Unfortunately, by the time it is passed to the callback, every attribute configured by the factory is included in the array returned. Moreover, the Evaluator is marked as api private.

• Discover NullPointerException bugs using FindBug

  - by alex2k8

  When I run FindBug on this code, it reports NO issues. boolean _closed = false; public void m1(@Nullable String text) { if(_closed) return; System.out.println(text.toLowerCase()); } While here it finds issue as expected: public void m1(@Nullable String text) { System.out.println(text.toLowerCase()); // FireBug: text must be nonnull but is marked as nullable } Why does it fail in first case?

  Does Asp.Net require ActiveX to make Ajax calls? I suspect it does because without setting "initialize and script activeX controls not marked as safe" in IE options ASP.NET UpdatePanels don't work. Am I correct?

• How do I remove/delete/expire a cookie immediately?

  - by dsimard

  I want to remove a cookie I set. If I do this by giving it a expiration date sometime in the past it gets marked as "expires: at end of session". I've noticed that other sites manage to delete the cookie immediately somehow. For example when you logout here on stackoverflow the "user" cookie disappears right away. How?

• svn says conflicted but it's really merged (TortoiseSVN)

  - by JoelFan

  Lately I've been seeing behavior where after an update svn shows certain files as "conflicted" but when I try to edit the conflicts, there are none (The "next conflict" and "previous conflict" buttons are disabled and if I scroll through the file, none of the lines are marked red). This seems to have started after I started working from a different repository than I had been working with, but I'm not sure if that's related.

  I'm trying the database first approach by creating an ADO.NET Entity Data Model using the Wizard with the Adventureworks2012 DB. Testing DB connection works, and the connection string is added to the App.Config. I'm selecting all the tables except the ones marked as (dbo) AWBuildVersion, DatabaseLog, and ErrorLog. When the Wizard finishes the .edmx file is blank, and if I view the file in XML view the EntityContainer is empty. I'm using VS 2010 & .NET Framework 4.0

• Session state server saying extended class no serializable

  - by jenson-button-event

  I am storing an object in session state (using local session state server), class def is: [Serializable] public class ExtendedOAuth2Parameters : OAuth2Parameters but the service is still reporting: Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. [SerializationException: Type 'Google.GData.Client.OAuth2Parameters' in Assembly 'Google.GData.Client, Version=2.1.0.0, Culture=neutral, PublicKeyToken=04a59ca9b0273830' is not marked as serializable.] How to get around it?

• Is there an extension or mode in Emacs similar to surround.vim?

  - by Chow

  Surround.vim is a nifty vim extension that allows you to surround blocks of text with , brackets, braces, and pretty much any arbitrary "surround" character. It supports paragraph and word surround, but I frequently use it in visual mode. I'm playing around with Emacs and wondering if there's something similar; something that will let me highlight a region and then have the marked region (or rectangle) enclosed with braces, brackets or tags.

  Hi Everyone: I am looking for some way to sync a online XML file with my iPhone application and only download the newest changed items. Each item is marked with a date attribute, so I assume this is possible.
