Hey Christof,

I can just register the SendMessage function and send to message to the correct application by window handle, or simply use the BroadcastSystemMessage and broadcast the message to all active application level processes. I've done both of these before in the past with 100% success.

I'm not sure where the complicated part comes in. VFP is always transmitting...never receiving in these scenarios. Granted, if the communication was two way, I'm sure you are correct about things getting messy.
