API? How do you people "extract" API stuff from new DLLs??

[AndyK]

I also need an advise on book which has basic VB functions and everything about them (where they used, what for, syntax, examples on how to use it, etc.)

Extracting functions from a dll: nope, no way. You can use quickview to see export functions of a dll (which are the functions you can call) but you only see names, no parameters...
A book? I don't know, MSDN helped me pretty much :-)

extracting API stuff:
for the DLLS I write myself, I write the VB Declare statements manually.
For other DLLS, I first check the APIViewer ADd-in in VB6 to see if there is already a declaration that I can copy and paste.
The next step is to check MSDN.
Some third-party DLLs come with VB "include"files or at least some form of documentation (crystal reports...).

Books? I don't know any better source for VB functions than the online docs that come with VB, or, if you prefer written material, their equivalent. You might also want to check out MS press http://mspress.microsoft.com
