Active window

[Sebastiano]

I want my Windows Form application to catch the current active window, doing
some works, and then reactivate the previous window. How can I do this with
..NET Framework? Or I have to use API functions?

Many thanks

Try the static property Form.ActiveForm to obtain it, and calling Activate()
on the form to make it active again.

But the active application/window isn't part of my program...it may be any
windows program! My application runs in background and, when a particular
event occur, it shows in foreground and becames the new active window. At
this time a want to save "a reference" to the old active window, so I can
reactive it when the user put another time in background my application.

I hope I have been more clear now

I see. I think you'll then want to call the API method GetForegroundWindow.
