   Shader debug/ VC2003 featuring DXSDK 2008 Mar
  First, I know how to debug shader.I installed VC2003.net.And DX SDK version is 2007 April.When installing SDK,I selectet the <DX extentions for VStudio>.When opening VC2003.net, I can find Menu:debug->Direct3D->Start Direct3D DebuggingThen today I uninstall my 2007 April SDK, upgrade it to 2008 March.I select the <DX extentions for VStudio>, too.But, when opening VC2003.net, I found that I can't find the debug menu............  -_-b.......How can I get the debug menu without reinstalling 2007 April SDK....Help me, please...........   
  The old shader debugging through visual studio has been gone for a long time.  Just use PIX...it provides a much better debugging experience than the VS extensions ever did.   ;  Thank you very much for ur replying.But.....What is "PIX"Where can I find it.........?   ;  PIX is an absolutely invaluable Direct3D debugging tool that comes with the SDK.  You should have a shortcut to it in your start menu in the group for the DirectX SDK.  There's documentation for it in the SDK documentation, or online here.I'd very much suggest using the version from the latest SDK (March 2009), as it has received quite a few bug fixes over the past year.
