Ive been using LaMothe''s "Tricks" book and been trying to use functions from header files he made that I include in my program. I often get error messages like these and I dont know what they mean or how to fix them Animal.obj : error LNK2001: unresolved external symbol "int __cdecl Load_Bitmap_File(struct BITMAP_FILE_TAG *,char *)" (? Load_Bitmap_File@@YAHPAUBITMAP_FILE_TAG@@PAD@Z) Animal.obj : error LNK2001: unresolved external symbol "int __cdecl DDraw_Fill_Surface(struct IDirectDrawSurface4 *,int)" (? DDraw_Fill_Surface@@YAHPAUIDirectDrawSurface4@@H@Z) Debug/Animal.exe : fatal error LNK1120: 2 unresolved externals Error executing link.exe. Ive seen errors like this a lot, not just in this example and they have always confused me. What Ive been trying to do lately is load a bitmap from a file and put it on the screen using his functions, but I cant get it to work. Any advice would be appreciated. Thanks

The problem is that you have to include the 3 library files into your project. Also, you have to go to the project then settings then link tab to include the libraries for directx...like ddraw.lib,dsound.lib,dinput.lib

or you can add this in your header file:

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