C++ and VB

I want to build an application in VC++ that will "talk" with an application in VB
What is the best way to do it?
Is there any place i can read about it?

IMHO the "best" way is via COM.
make your VB "app" an ActiveX DLL (or exe), import the Typelibrary of the COM component into your VC project via the "#import" directive in VC 6 and voila call the properties and methods "the COM way".

For further reading, refer to MSDN, particularly the knowledgebase.

If you want to have to apps running at the same time and you want to speak at each other, try to send Windows-Messages. There's a way to handle WM-Messages in VB.

Otherwise try to build in VC an ActiveX-Control (.OCX). It's VERY easy to use it with VB.

Another way is to build a VC DLL (it's no real app, but it can show dialogs etc.). Use _stdcall function() to export functions because VB can only import functions with this convention.
