Why doesn Intellisense offer code completion options for DX 8 interfaces under VC++?
The problem is that the IDE is drawing its information from the older headers that were installed with VC++. It will also use information from the headers in your project files, though simply using #include does not cause them to be inventoried from the new headers. You can enable Intellisense with the new interface by adding the header files containing the definitions to your project (e.g. D3DX8.H and D3D8.H for Direct3D). Right click on your project in the FileView pane, select “Add Files to Project…”, then select the necessary include files from the DXSDK\INCLUDE\ directory.
