hi there!
im total newbe and have a problem.iv got Andre Lamothe book "tricks of windows game programming gurus" and when im compiling first example in this book ive got errors:

Warning 1 warning C4101: 'ps' : unreferenced local variable
Warning 2 warning C4101: 'hdc' : unreferenced local variable
Error 4 error LNK2019: unresolved external symbol _DirectDrawCreateEx@16 referenced in function "int __cdecl DD_Init(int,int,int)" (?DD_Init@@YAHHHH@Z)
Error 5 error LNK1120: 1 unresolved externals

and some more.but if go to project properties and change character set from Unicode to multibyte I end with errors 4 and 5 only.

now the book is from 2002 so the .cpp files and Im using visual studio 2012 express with windows 8 with directx sdk that comes with it.
I don't see ddraw.lib in sdk folder and don't know what to do and how to resolve the errors above

The warnings don't really matter.

The errors are link errors. If you look at the documents page for DirectDrawCreatEx you'll find what lib you need: http://msdn.microsoft.com/en-us/library/windows/desktop/gg426116(v=vs.85).aspx

Then in the project settings, linker section, make sure you are linking to that lib.

However, I honestly don't even know if DirectDraw functions are still part of directX sdk. That is pretty old stuff. But I suppose it would still be in the libs for directX 9.c

AFAIK Direct Draw was depreciated in dx8, and removed altogether from dx9(someone with better knowledge can correct my timeframes). You will either need to procure an older SDK, or attempt to port the code to a different api, such as the more modern dx11
