Question

I am developing a WPF project in vb.net and have multiple windows in it. When user selects a menu item a new windows opens and the problem is when the user clicks on other menu item the current window should close by itself.
How do i achieve it?
Thanks!

I think you mean this based upon your comment:

Class MainWindow 

  Public Win3 As Window3 = New Window3()

  Private Sub Button1_Click(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles Button1.Click
    Win3.Show()
    Me.Close()
  End Sub

End Class
