By the way, you can access the DirectX C interfaces (or any COM interface for that matter) from C++ by #defining CINTERFACE before including the header containing the interface.
Also, you don't have to use lpVtable, you can always use the macros they provide (your preference). -Wade Wednesday, February 06, 2002, 3:11:14 AM, you wrote: B> Getting DirectX to work from cygwin GCC essentially can't be done from C++, B> but can be done from C.
