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 a Multicast UDP session to a number of remote hosts 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.

Can you pls upload "Cleint PC.VI" with all dependencies (VI's and type def's)?
