How do I close a form when a user clicks outside the form's window?

Question

I want to close a System.Windows.Forms.Form if the user clicks anywhere outside it. I\'ve tried using IMessageFilter, but even then none of the messages are passed to PreFi

SIMPLY WAY : on Form1 use this code to call form2:

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles     Button1.Click
    Form2.Owner = Me
    Form2.Show()
End Sub

and then use this code on form1 again :

Private Sub Form1_MouseClick(sender As Object, e As MouseEventArgs) Handles Me.MouseClick
    If Form2.IsHandleCreated = True Then
        Form2.Close()
    End If
End Sub
