Why can I access intellisense for DX9Interfaces under VisualStudio.NET?
The problem is that the IDE is getting it’s information from the older headers that were installed with VC++. It will also use information from these headers in your project files, though simply using #include does not cause them to be inventoried from the new headers. To enable intellisense with the new interface you have to add the header files containing the definitions to your project (e.g. d3d9.h for Direct3D). Right click on your project in the Solution Explorer, select “Add Existing Items…”, then select the necessary include files from the DXSDK\Include\ directory.
