Gui demo to start another app with termination notification

[hutch--]

This demo shows how to run an external app asynchronously without any "shell" style procedures, wait states and the like and receive notification when the external app terminates. The price is you must be running an external app you wrote yourself as it sends a registered message using the HWND_BROADCAST handle to the system that is trapped by the calling process as termination notification.

The advantage is in a normal GUI application is that you can keep working with the calling app while the other is running asynchronously and receive notification when it has finished.

Hello,
There is no price proceding as the sample i have joined
It used  invoke FindWindow,addr ClassName,NULL
You have write it , so you know it's classname,and you got i's handle and there is no need to broadcast the message.
The sample create an atom ,that is join with the message, so the two aplications can exchange data.
