Does it have to be 2 applications because it might be more appropriate to write DLLs and use them from VB application. Depending on C++ code, it might be a managed DLL in which case it offer little advantage if any over writing the whole application in a single language.

Otherwise, it might be a mixed-mode DLL which will give you a lot of flexibility...

You are talking about inter process communication (IPC). If the two apps are running on one PC which I assume they are then shared memory may be the best option.
Look at these two articles as a start:
