The user would click a command button and the VFP code will pass control information to the VB program for it to act upon. Once control has been passed to the VB app the user does have some interface with a form. Upon completion of the process the user will exit and needs to return to the next command in the VFP code.

I hope the following can help you.
First you declare in Visual Foxpro code a var just prior to execute the VB4.0 program which includes /N1, the name of your application in VB4.0 and the paramters you wish to pass like the following:

var = "/N7 VB40.EXE" + THISFORM.textbox.Value

After this, you execute the VB application with

RUN &var

NOTE: the VB application must be modal.

To reanude the VFOX application you need to test if the VB application is active. You can test with the Windows API, or with a flag or a file exists. While this file or flag exist you are in a DO WHILE loop with INKEY(0.xx).
