DirectDraw Gamma

Hia! Since I am a newbee on this with directx and stuff... I find it hard to make a functioning application with DirectDraws gamma function. I followed this article I found here on gamedev.net : http://www.gamedev.net/reference/articles/article998.asp But I realized that it probably isn't as easy as it sounds... Well, what except ddraw.h and ddraw.lib do I have to include and etc. to get this working? I checked out the SDK documentation, but under the "Required:" they only said ddraw.h But then again I downloaded the full SDK with examples and etc. where I found an example with ddraw gamma. That example had also these files: ddutil.h ddutil.cpp dxutil.h dxutil.cpp So... I did the same, included them in the workspace in a folder "Common". Well, then I thought it should get working... but when building the project I get 2 unresolved externals insted: dxutil.obj : error LNK2001: unresolved external symbol __imp__timeGetTime@0 ddutil.obj : error LNK2001: unresolved external symbol _DirectDrawCreateEx@16 So, I was thinking that maybe there is a "#define" or something that I don't have, hoping for someone here to help me out? thx!
