>What about a good book for functions, structures, syntax, etc., for Win32 and other DLLs, etc.? Specifically for use in VFP. I have found similar books but only for VB, C++, etc., but not for VFP. I have also just started a subscription to MSDN but can not really find anything detailed enough to be useful.

I know what you mean. We had to do all kind of stuff with network API recently. We looked for books, references, etc. but it was difficult to find something which deal with Visual FoxPro. We finally ended up by doing business with a C++ and Visual FoxPro specialist.
