>Isn't there a way we can achieve this on application's environment level. What if none of the forms are open while the application is running?

Noman,

Check out Visual MaxFrame framework... If I remember correctly Drew had an application level timer that would close down the ap after a certain amount of inactivity... however, I don't remember how he determined inactivity. I know this was a feature in the Public Domain version that is in the files section here.
