They also need to be compiled using the __stdcall convention. Once you have your library built, you will need to use a declare statement in VB to indicate what library the function is in, how to reference it, its params, etc..

There is nothing wrong with using this method to access functions in a C++ dll from VB.

It is somewhat easier to build a COM dll and use it from within VB (once you get some COM basics under your belt).
