Hello Vlad,

How do I get the id of the message I want to retrieve? Is it the window handle of the sending program? Do I register the message myself with RegisterWindowMessage?

I have tried both of the above and it locks on the GetMessage()line. Should I use a timer and PeekMessage() as an alternate method or is GetMessage the best function?

Thanks,

Jeff
