Hi all,new to gamedev.net & game programming.Looking for help on how to write a reinterpret_cast to get the surface up and running.Im using Vc++ 6 and heres the error, C2664: ''CreateSurface'' : cannot convert parameter 1 from ''struct _DDSURFACEDESC2 *'' to ''struct _DDSURFACEDESC *'' Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast Thanks Donald

If you''ve never gotten that error before, I suggest you RTFM or get more experience. Either way, I think you can fix the problem by typecasting it like this:

MySurface = (_DDSURFACEDESC *)CreateSurface(...);

You might also want to consider why it''s asking you to do this. Are you certain you want to use a DDSURFACEDESC instead of the (seemingly-newer) DDSURFACEDESC2?

Later,

Actually, you probably can''t even do that, if one isn''t derived from the other or there''s no constructor that can handle it.

Try checking to see if there''s a different function you should be using: ie. one that takes a pointer to a DDSURFACEDESC2 instead of a DDSURFACEDESC. Sadly, my memory of DirectX details has lapsed somewhat, but ask on the DirectX forum if you can''t work it out.

Just Figured it out left out the 7 in my call to directdraw.
