combining visualbasic en VC++

I have a Vb program that creates an array,I have an VC program that analyses data. Is it possible to combine these to programs. So: I want to start the VB appl. after the array is filled it calls the c program
When this is finished it returns to the VB program. Like a subroutine.

Perfectly feasible. This is actually the way to enhance performances of apps.

Post your code, if you have any probs.
