DirectDraw 1.0 works...why not verion 7?

Go to the Tools -> Options -> Directory menu, add the ''include'' and ''lib'' directory of the DX7 SDK in the appropriate directories lists. Make sure the SDK directories are *first* in the lists, otherwise the compiler will use the old version which is provided with MSVC.

Thanks it worked.
