Using C++ DLL IN VB6 app

I've done some searching on this and the info was fairly scattered.

Basicly i've made a neural network in c++ and was wondering how simple it would be to compile it into a dll and write a front end in VB.

As far as i understand i can't use class' written in C++ only non member functions, which i guess is easily solved by having non member class functions create my class' etc

Is it as easy as using the declare statement to access the functions in my dll? (as if they were api functions)??

You would just do something similar to

VB Code:

Public Declare Function RWTInitialize Lib "c:\rqt\dbacc.dll" (ByVal sQuoteID As String, ByRef nErrCode As Long, ByVal sErrText As String) As Long
