What is the event to trap when user clicks X to close form?

[Robert Dufour]

On my form if the user clicks the upper right hand corner to close the form
I want to trap that event and do a check to see if closing is allowed, if
not, I want to stop the form closing action.

Can anyone tell me how I can do this?

Thanks for any help

Form_Close event is fired when u try to close form.

Don't forget the Form.Closing Event. Which is fired before the disposal.

In addition to the other replies:

If you are using .NET 2.0, check out the form's 'FormClosing' event too.

There is also the option to override the WndProc method if you really
needed to.

Thanks,

In VB6, there was the QueryUnload event which had an UnloadMode argument, one of
which was vbFormControlMenu which was specific to the "X" button and the control
menu, "Close".

In .Net, AFAIK, there is no functional equivalent short of using the WndProc method.
FormClosing event will fire when the "X" button is pressed (3-User Closing), but it
also fires for the same reason if Me.Close() is called - 3-User Closing.
