Start your C programm with startapp and provide the input values into the commandline or a file.

Write the output values to a file and raed it in in VB.

Write a flag at the end, to signal vb tha everything is done.

The environment is multitasking !!

You can run the C executable synchronously. To see how that is done find setup1.vbp on your system.

setup1.vbp should come as standard with your VB installation. It is the setup program that will be run when you create a Setup using the Setup wizard (vb5) or Package and Deployment wizard (VB6)

Anyway, depending on what version of VB you're using check out the FSyncShell or SyncShell function defined in that .vbp. That will avoid the multitasking problems thomasheilig is talking about.
