• Visual Studio 2008 (Pre-release) Is it possible to pre-fetch data from a relationship or make it fetch on-demand instead of requiring a call to .Load()?

  While on the subject of loading foreign key references... Is there some mnemonic I can throw into the LINQ query to tell LINQ to Entities that I want to pre-fetch all of the type data because I want to filter on it When I do: var filteredQuery = from game in gamesDb.VideoGames where game.Type.Name == "Nintendo Wii" select game; foreach (VideoGames g2 in filteredQuery) Console.WriteLine("{0} : {1}", g2.Title, g2.Type.Name); That thing works fine, and I don't have to loop through and call TypeRef.Load() Is there something I can stuff in the query when I'm not using a where clause that will force the TypeRef to pre-fetch Oh, something else occurred to me.. The ORM.NET code I used and modified h ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Render to Texture Inside Shader?

  I'm sorry if this is a stupid or obvious question, but I am completely new to shaders. Is it possible to render to a texture inside of a shader For example I want to render to a texture in the first pass and then use that texture in the second pass. I am currently using XNA's render to a texture successfully. However I was wondering if it was possible to implement it inside of a shader, because I feel it would be faster, not to mention make the XNA code simpler. My gut feeling is that it is not possible, however I am kind of confused by RenderMonkey. It uses Render Targets which appear to do what I want. However, I think it may just be doing some DirectX render to a texture operations in the background. Y ...Show All

• .NET Development Visual Studio 2005

  Hi All, I am using VS 2005 (ASP .NET 2.0 using C#) with SQL Server 2005 to develop a web app. There is only one dataentry screen in my app and rest are all queryable screens. The database is small.

• Visual Studio Team System How to setup TFS MSSCCI plugin to connect to SSL-enabled TFS Server?

  I am unable to get the TFS MSSCCI plugin to connect to an SSL-enabled TFS Server. How can this be done I followed the following 2 walkthoughs to enable and require SSL: http://msdn2.microsoft.com/en-us/library/ms242875.aspx http://msdn2.microsoft.com/en-us/library/aa395285.aspx We were recently required to put all web trafic under SSL and now we are unable to have our VS.NET 2003 clients to connect to TFS.

• SQL Server OLE DB Source to Flat File Destintation using Fixed Width Columns - determining source column width

  Hi, I am trying to create a program that transfers tables to flat files. At this point in time, I have suceeded in created one that creates delimited files. However, I am now trying to create fixed-width files as you can do with the SSIS designer, but programatically.

• Visual Studio Team System Unit Test Adapter threw exception: System.NullReferenceException

  Hello, maybe anyone can provide a solution to the following scenario. I have a device project that compiles fine and I have a unit test project for this device project that was working well too.
