• Game Technologies: DirectX, XNA, XACT, etc. Rotating TransformedTextured Vertices around a specific point? (MDX, C#)

  Hello everyone! What I am trying to do, is to draw a textured 2d square using on-screen coordinates (therefore using TransformedTextured, and not PositionTextured), using vertices, and rotating the square around a specific point in the z axis, however after a good hour of googling, I can only seem to find examples of doing this with PositionTextured vertices, I am beginning to wonder if I am actually looking in the wrong direction. Is there any way I can convert on-screen coordinates to world matrix coordinates I would appreciate any help, hints or examples on how this could be done. Thanks in advance! //Avi I see. But as far as I can ...Show All

• Visual Studio Express Editions SQL Exception -- Failed to generate a user instance of SQL server

  I am a beginner and was doing a lesson on the videos on my laptop.  I created a data base according to the lesson and everything went fine.  I went back to the project the next day and received the following message when I tried to expand the "+" sign preceding the name of the data base in the Database explorer; "Failed to generate a user instance of SQL server due to a failure in the starting process for the user instance.  The connection will be closed."  The project would not run, showing on error on the loading line of the program.  After looking around the forum I failed to see anyone else who had this proble ...Show All

  Hi in VB.NET 2005, what is the best way to retrieve and parse HTML data from a URL, a bit like a search engine crawler I am building an app, where I need to parse a website, and collate data from it (the website uses some tags that I could pull out to get the appropriate bits of data).  I want to be able to do this in a thread, and just update a DB with the data, and give the client app a status update of the progress.

• Visual C# Please specify the assembly explicitly in the type name.

  I am trying to set up Global.asax and a Code behind page but I am getting the following error: The type 'Global' is ambiguous: it could come from assembly 'C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\aaw\2de92fac\492e65b1\App_Code.gyumgjze.DLL' or from assembly 'C:\Inetpub\wwwroot\AAW\bin\App_Code.DLL'.

• Smart Device Development Contacts application and event handling

  Hi, i have an app that opens the contacts application and sends WM_CHAR messages to the listview. WHen tracing through the code, i see that the lookup works. For instance, if i send "j" followed by "o", my list will filter with each send character and i will see, for example, only names that contain "jo". HOWEVER, when i am not in debug mode and stepping through, this does not work. Is ee the text "jo" in the text box, but the listview shows all contacts. I ahve tried adding DOEVENTS and sending WM_PAINT as well as warrping the WM_CHAR with WM_LBUTTONDOWN and WM_LBUTTONUP...all to no avail. ...Show All

• Visual C++ Why doesn't the following compile under VC2003?

  Why does the following code snippet not compile in Visual C++ 2003 It compiles under GCC, so why not in VC2003. What is wrong with it // Outter class: class Outter { public: // First inner class: template class Inner1 {}; // Second Inner class: class Inner2 { public: // Method definition: Outter* Inner1() {} }; }; Well, it compiles fine under VC2005. And it compiles fine under VC2003, here. // Method declaration: Outter Inner1(){} // Method definition: Outter* Inner1() Those two lines are different, which one is it If I add the *, then it compiles in 2005 and not 2003. So I would guess that this ...Show All

• Visual Studio Team System How would you respond to this...?

  My boss sent this email out to the dev team. It seems a bit draconian to me, and quite condescending...how would you respond I’d like to make one thing very clear. Nobody should be writing code without a plan. This means written documentation (usually a design document) on what is to be done including but not limited to system and component description, test cases, programming interfaces and use cases where appropriate; what is to be done and why it is going to be done. The design should be reviewed as appropriate: in a meeting and/or by your peers, by architecture and by [John Doe] or me. Before you complete the document(s) i ...Show All
