Windows API Reference for C#, VB.NET and VB6

Windows API Reference for C#, VB.NET and VB6

The
Windows API (application programming interface) are the low level workings of
Windows. It offers high performance, and lightweight code, but it is very
sparsely documented for .NET programmers. This section provides a rough guide to
the Win32 API from a C# and VB.NET developers perspective.
This guide is not definitive, and will evolve with more
content over time. Currently listed are over 1,600 Windows API functions. To use
this guide, firstly expand the one of the libraries below by pressing the

icon. Once you have found the function you are looking for, click on
the library name itself.
