Message sent to System Tray App

Hello -

Anyone have a sample of code (or set of componets to recommend) that would offer one main application to send a message to another application that is sitting in the system tray? It would be good too if the message would pop up the message right over the system tray application repeating the message just sent (like a balloon form) instead of the tray icon flashing (like most IRC apps) forcing the user to click on the system tray icon to get the message.

For example:

App1, sitting in the system tray area, is waiting for a message.

App2 is loaded and user types in a message into an edit box and then presses the 'ok' button.

App1 pops up a 'form' indicating a message was sent and the message was.....

TIA -
