I think what InDirectX is trying to say is that if the error is "unresolved external symbol" then it''s such a common problem with beginners to DirectX that you should have searched the forums before asking the question, as it''s been dealt with many times before.

The first step would be downloading and installing the directx sdk. (www.microsoft.com/directx)

Just so that everybody that doesn''t know - the DirectX 5 SDK comes with VC/C++ 6, so the above call should work as long as the appopriate headers are included and libraries linked.

simo, are you including "ddraw.h" in your project? It should be at the top of the file using the DirectDrawCreate function call.

Well, he did say it was an unresolved external, which is generally not indicative of a missing header...

Link you DirectX library to the program. If your using DirectX 8.1 add:

#pragma comment(lib, "d3d8.lib")
#pragma comment(lib, "d3dx8.lib")

That should do it.

EDIT.

I didnt read it fully. Don't add the above, add:

#pragma comment(lib, "ddraw.lib")
