why "Error : IActiveDesktop undeclared indentifier" occurs even after incluing the specifed file ?

Question

I am using IActiveDesktop interface to change wallpaper . I have included files "shlobj.h" , "shlguid.h" for that in my MFC project.

But still i am getting error : "undeclared identifier IActiveDesktop" . Can anybody tell me how to resolve it ?

There are a few more includes you'll have to add manually. See ActiveDesktop Compilation Errors Under Visual C++ 6.0 MFC KB article.
