Hi Fred,

I don't think you're going to have any success in trying to use SendMessage() to do this, especially in view of the way VFP handles windows messaging. However, there is an alternative that will do what you want, and, BTW, uses Windows messaging services: DDE. DDESetTopic() allows you to define a UDF name that can receive the messages. If the FPW app does need to receive messages back, you'll only have to initiate the connection with the VFP using the native commands. No need for foxtools and declaring the function.
