• Game Technologies: DirectX, XNA, XACT, etc. getting the position of vertices in a mesh

  Hello everybody. I am trying to get the position of vertices in a mesh. That seems to work fine except that the data I get doesn't make sense. To me. I use a lock on the mesh.VertexBuffer (both versions... an array and a graphics stream with same results) and use the returned array or graphics stream to look for vertices that have a Position "of interest". The only issue is that some "Positions" have coordinates in scientific format which doesn't make sense since the mesh renders nice. Some code (used on ball.x shipped with the SDK. I have tried other meshes and the only one that has "n ...Show All

• Visual Studio Team System InfoPath projects fail in TFS

  If I add a infopath project to a source controlled solution other teammembers donot get a working infopath project when they get-latest the solution. They get various errors, primarily caused (as it seems) by the missing of the InfoPath files. They are not retrieved from the source control. I stored the InfoPath project in a subfolder under the solutionroot. [EDIT: A work around is to make the files writeable (after a manual get from the source control) and then reopen the solution. The infopath project opens fine then. Compiling became the next problem. The output path of the enclosed c# project shoud be .\ (instead of bin\Debug)] Anyone in ...Show All

• Visual Studio 2008 (Pre-release) LINQ support on deployment

  Hi to all. I am a new in the LINQ. So I have a basic question: I downloaded the LINQ and installed it on my developer machine running VS2005. Used some LINQ code in my application. Now I need to deploy it on the production machine. Do I need to install some LINQ support besides the .Net 2.0 framework Thanks FWIW, the LINQ CTP is not for production use per the EULA. If you want to try it out for prototyping, you will need to have the DLLs in the /bin directory of the CTP on the machine you are trying it out on. For code-behind, you will need the compiler(s) as well. By default ...Show All

• Visual Studio Express Editions Searching for Text

  How can I search for Text in TextBox or in Rich TextBox like that Find button in notepad and Wordpad Please help in this and tell me if it just code or if there is a tool to do that. Thanks. Use the 'Contains' or the 'IndexOf' methods of the Text property of the textbox or rich textbox to search for strings. 'Contains' will return a boolean value indicating whether a string contains a particular substring. 'IndexOf' is more versatile & returns the index of the substring. ...Show All

• .NET Development Multithreaded Windows Service (C#)

  Hi, I am trying to implement a multithreaded windows service using c# and .net 2.0. I have the Main() method call ServiceBase.Run(new ServiceClass()) which loads the service by instantiating the class and calling OnStart(string[] args). I have read a fair amount of multithreading tutorials but none of them seem to go into much detail. We are still early in the design stage and trying to figure out how this system is going to work. I am very open to any suggestions.

• Visual Studio Team System ? VS2005 RTM + Team System Beta 3 = OK ?

  Ok, so we've got the VS2005 RTM on MSDN Subscriptions now - Yippee! But: What about Team System Can we use the existing Team System Beta 3 with VS2005 RTM I know there was talk of a "Team System Beta 3 Refresh". Will us Team System users need to wait a while before installing VS2005 RTM Or can we go ahead and install it, and Team System will continue to work with it just as before [EDIT] I see that the Visual Studio 2005 Team Edition contains Team Foundation Server - so I guess I just need to install that. I think I'd better finish downloading it and see what the FAQ has to say before asking any more questions... ...Show All
