closing a window

If I am closing a window I want to know by which way the window gets closed (i.e) by a mouse click in the close icon or alt+f4. Is there any event for getting this info?

Whether or not you can trap specific WM_...-messages to distinguish between them, don't do it! One of the fundamental pricniples of usability is no suprises: live up to the user's expectations. Do what every other application does, especially when it comes to the absolute basics.

No matter which toolkit you're using there are always events for clicks on the close button, keyboard events for Alt+F4, menu click events for menus etc. All you have to do is enumerate the possible ways to quit your application, change the event handlers to set a variable to their corresponding value, and check that variable in your application close procedures.

I don't believe there are any events specifically to give you this information, no. The FormClosingEvent provides a FormClosingEventArgs with a CloseReason, but the reason doesn't distinguish between using a mouse or the keyboard. It only distinguishes between a "user close" event and things like "the form owner closed" or "the application was shut down from task manager."
