This example builds on top of the brilliant .NET integration VI's for Windows Balloon Popup's found here and integrates it with TCP/IP communication, allowing you to send a command over TCP/IP to a remote host which will then show a Balloon Popup on the remote system so (for example) sending the command "UPD" could inform a remote client that an update it available for the application.
The Top Loop deals with the TCP Communication, listening for an data from the Server, while the bottom loop deals with the Balloon Popup.
