It''s a nightmare ,really. I unpacked the Lib and Include files in DX7SDK. And define it''s dir in TOOLS\OPTION\DIR ''s TOP PLACE. But after include ddraw.h and started my programming, i found that LPDIRECTDRAW7 couldn''t take any effect. It looks there isn''t any defination for it in ddraw.h,but it''s not the fact. The same happened on all other structs and longpoints which are not in DX5SDK but DX6/7SDK. So ,What''s wrong with them? By using "List Members" in VC6 ,i can find IDirectDraw/2/3 but not IDirectDraw4/7,So may be there some things need to be setup?

copy all the headers of the dx7sdk into \include dir of VC, and all the libs into the \lib directory and it should work

Go to the project->Settings->Linker
and remember set d(input,draw,sound).lib and dxguid for default Directx Guids.
I think you haven´t moved Dx7 headers to header directory. There comes DX5 or 6 with VC so just move files from DX7 package to /lib and /include "and overwrite all"
