app close warning

hello,
does any one know which windowsform procedure i need to overrirde to control application exiting? for example, to show an "are u sure u want to exit" dialog.

VB Code:

Private Sub Form1_Closing(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles MyBase.Closing
        If MessageBox.Show("do you want to save your changes before quiting", Me.Name, MessageBoxButtons.YesNo, MessageBoxIcon.Question) = DialogResult.Yes Then
            e.Cancel = True
        Else
            e.Cancel = False
        End If
    End Sub

:)

VB Code:

Private Sub Form1_Closing(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles MyBase.Closing
 
e.Cancel = True '  use this in if block
'to cancel exiting your app 
 
End Sub

works like a charm.. thanks, and welcome back pirate
