Mike, I've tested calling a simple VFP exe from FPW and it works great.
Just another few questions

1. Is it possible to send parameters back to the originating FPW app ?
2. Is there a way of telling if the VFP app is running, and if so some way of calling it from FPW.

Basically, I will be using a small program to validate codes from a lookup table and to write a record. Loading the VFP exe each time (from my FPW app) will probably be too much of an overhead and take too long .
I wonder can I somwhow , first check if the VFP exe is running, and if so send it my parameters ?

regards,

Gerard
