How I know API Functions ???

[VB7]

The question in subject

Lots of them are at these sites:

http://www.vbapi.com
http://www.allapi.net

And you can buy Dan Appleman's Visual Basic Programmer's Guide to the Win32 API (http://www.vb-world.net/books/danapi/) for a good price which may help you out with API function a lot as well.

msdn.microsoft.com and visit the Platform SDK section.

You can find a helpfile 'win32.hlp' for API under http://www.crackstore.net with a detailed explanation of the most functions you need!!!(But there is a disadvantage it is in C-Language)

Also, when you install the MSDN from your CD, it should install the PSDK files with it, so this eliminates the need to go to that the msdn site.
