I have one Main application where I have 3 different command buttons. Each command button has to open different executable applications, but the Main applic shouldn't be closed, it should remain on a screen. Also when user clicks on one of the command buttons it should open the appropriate executable. When user done with one exec.,it's should be minimized and placed down in main application. When user want to click again at the same command button, it should check if this executable already opened, then maximize it, if not opened then open it.
if something unclear, let me know.
