Hi Tut :)
How are you ?

If you are really new to API, this is how you start:
1. Think of calling the DLL is just as simple as VFP command. Go with a simple API first, like the one that Jos already mentioned, until you feel comfort for using/calling DLL
2. Learn a bit for C language, at least for "type" & "structure". How to convert it into VFP
3. Get yourself a book (most of the good book for Win32API comes in C language). Find a good reference for Win32API, like Microsoft (MSDN) site, Borland site, allapi.net, news2news, and you will find more websites that provides Win32API help, if you want to search for it. UT forum also has one section (Windows API functions), many people can help you.
4. After you know all about that, then you can start using more and more advanced API.

I have one DLL here in download area, it's a wrapper to Win32API.
