Closing event in vb.net

Closing event in vb.net

VB .NET includes a new Closing event for a form. In this event, you can trap — and abort — the user’s attempt to close the form (by clicking the x in the top right or by pressing Alt+F4). Here’s an example that traps and aborts closing:

====================================================================

Private Sub Form1_Closing(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles MyBase.Closing

Dim n As Integer

n = MsgBox("Are you sure you want to close this form?", MsgBoxStyle.YesNo)

If n = MsgBoxResult.No Then

e.Cancel = True

MsgBox("This form will remain open.")

End If

End Sub
