Thank you, Kudzu, but I guess I didn't explain the scenario well enough. The "Whatever you want" is coming from a separate non-IntraWeb application running on the same computer as the IntraWeb one. I am able to have the Intraweb UI sense, for example, a button push and send a "Which one" message through a Windows pipe to the listening subroutine in the other program. That program generates a response and sends it back through the pipe. That response is not being seen by the IntraWeb application.
I think it's perhaps a two part solution. One, to somehow receive an interprocess message from another app, and two, to refresh the IntraWeb web page to the user with the contents of the message.
