another helpful resource was originally introduced by Bruce McKinney(author of Hardcore VB); it's the win32 type library. He has since given up the development of this tlb to peet morris of TMS(The Mandelbrot Set) who, with his colleagues have taken the type library to a new level. The TLB and IDL source code(if you're in to writing type libraries) is freely downloadable here: http://www.themandelbrotset.com/html/typelib.html
...just drop it in your windows or system32 directory and then select it from projects>references in vb. it's very cool, very easy to use and encapsulates most of the win32api. I do wish however, that some of the other api's are added to the type library sometime soon.
