Presented here are a collection of programming tutorials for Windows. The tutorials cover various Windows programming topics, but most concentrate on the user-interface aspect of programming. All tutorials and source downloads are in the C programming language. No external libraries such as MFC are required to build the source code presented in these tutorials.
A friend of mine just shared this link with me and all I can say is DAMN, what an awesome site for information.
