Help w/ DX

Hi, I''m working on my engine as said in my previous post. Anyway I put all my windows and DX initialization in functions that are in seperate files. Just so i don''t have to see all the windows stuff an DX inits. So i have 3 files. My WinMain(), a header which has my windows init and dx init functions phototypes and the implementation of these functions. I include ddraw.h in both my main and implementation files. I''m getting unresolved external symbol _DirectDrawCreateEx@16 link2001.<-- happening in my implementation file. I looked it up in online help and couldnt find anything helpful. Please help!
