net send...

Does anyonw know if there is any way to create a program that can detect when the "net send" function is used on the WinNT network, so that when the program is running, it can detect if there is a message is sent to that machine.

Any suggestions at all would be greatly appreciated...

Owen.

Right then.
The pop-up window has the title "Messenger Service" so you need to get titles of all the running apps and then loop through them to find it

I've just put a Msgbox here when it is found.


paste this into a module and call it from a timer control or a timer() loop

Code:
