• Game Technologies: DirectX, XNA, XACT, etc. Future D3DX's not supporting SM1.x??

  I saw this in the October SDK readme October 2006 DirectX readme! wrote: Preview Release of the new HLSL Shader Compiler for Direct3D 9 Targets This release has a beta version of d3dx9d_31_beta.dll that includes the Direct3D 10 HLSL compiler enabled for Direct3D 9 targets (shader models 2.0 and later). The new compiler has no support for 1_x targets. This debug-only DLL allows developers to utilize the new Direct3D 10 HLSL compiler for their Direct3D 9 shaders, and will become the default compiler for all Direct3D shaders. Please try the new compiler by building your application with d3dx9d_31_beta.dll instead of d3dx9d_31.dll. Does this mean in future SDKs SM 1.1 will not be supported any more, or is this limitation j ...Show All

• Visual C# Defining Public strings Visual Web Developer

  I am using Visual Web Developer, it's a great product, but I'm stuck, I have done a lot of research on trying to define public strings, Examples I find are public class SData { public string sdata } This is quite logical, but the problem is using them in the code generated by Visual Web Developer using System; using System.Data; using System.Configuration; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; // I would like to define some public strings of data that // could be used thru out, but am at a lose as to where to // Place them. ...Show All

• Software Development for Windows Vista problem in sdk sample "domdemo"!!

  I am evaluating MS AEC DMO. I found that Windows SDK sample "domdemo" in "Multimedia\DirectShow\DMO" can not work correctly. When i select "AEC" DMO and click "Play" button, the sample shows the error message "streaming data failed". After debuging, i found that ProcessInput is always return "E_FAIL"! Why this function can not work well Who can tell me how to use AEC DMO in playback .wav files Thank you very much!

• Visual Studio Team System The project file * has been moved, renamed or is not on your computer

  Hi, somehow my VS2005 Team Suite is still looking in the old/wrong path for my project file and I can't figure out why it's looking there. So here's the deal: A while ago I created a solution with 3 projects in it; two C# class projects and one Website project. Life was good and everything worked fine, wonderful. Since then, I have acquired a new development workstation and have been developing happily ever after... until today, when I had to revisit my old Solution. Upon opening the old solution file I was prompted with a dialog indicating that it could not load one of my C# class projects because it has been moved or renamed. I OK'd the dialog and attempted to re-Add the project. To try and add my project back into the soluti ...Show All

• Visual C++ Why I can't complie below code in VS2005

  Because of std::swap function, I can't compile below function. but if I don't specify template parameter, it is compiled very well. I wonder why I can't specify template parameter when I use swap function, but if include <utility> instead of <vector>, I can use std::swap specifing template paramter. I think it's Microsoft STL library bug..., it is needed to fix it. #include <vector> // if I include <utility> I can compile below code. template <class T> class CTest { typedef CTest<T> ThisType; T* m_Array; public: void Swap(ThisType& other) { std::swap<T*>(m_Array, other.m_Array); } }; int _tmain(int argc, _TCHAR* argv[]) { CTest<double> test, test2; test.Swap(test2); ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Rotating model, with multiple parts

  Hi all, One of the persons on my team has designed a model, that has more than one part. When we try to rotate the model in XNA, it rotates every piece. If there anyway to choose to rotate the whole model, instead of the piece Here's a hack that will probably work: Tell your artist to set the all the pivot points for the model as one location. Then, all the pieces will only rotate around that pivot point, not their individual pivot points. There might be a better software solution, but I don't know it. ...Show All

• Visual Basic How do I remove selected items from a listbox using a for each loop

  I am stumped on this,when the teacher explained it in class it made sense but when I try it at home I can't figure it out.I am not asking you to do my work for me,I am just asking for a hint something to get me started in the right direction. Thanks well you cannot remove the items within a for each loop like what you maybe wondering as you cannot remove, or add items, when going in a for each loop and checking to see if the current item is selected you would remove the items selected and the SelectedItems returns back the collection of items selected. Once got, use a foreach loop on this and remove the items: for each currentItem as object in Me.theListBox.SelectedItems Me.theListBox.Rem ...Show All

• Visual Studio Team System Setting location for a custom dll

  I've created a custom dll which contains all of my custom tasks which I've written for MSBuild. The only problem is that all of my builds need this task. I just copied this dll into the directory for each build, but when make changes to the dll I have to update it for every build. Is there a better place I can put this so that I don't have to do this whenever it is updated Thanks. Thanks a lot Steve, I think that I will create a team build project for this dll and then do a post-build copy task to copy it to a common location so that it will always have the newest version. ...Show All
