How to set the system to reload the window if there is no mouse action occurrence in 10 sec?


I have tried this code, but its not working. it didn't reload after 1 minute...

 Class Window2
    Dim dt As DispatcherTimer = New DispatcherTimer()

    Private Sub Window_Loaded(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) _
      Handles MyBase.Loaded
        AddHandler dt.Tick, AddressOf dispatcherTimer_Tick
        dt.Interval = New TimeSpan(100000)
        dt.Start()

    End Sub

    Private Sub dispatcherTimer_Tick(ByVal sender As Object, ByVal e As EventArgs)
        
        If MouseAction.None Then
            dt.stop()
            Me.Close()
            CommandManager.InvalidateRequerySuggested()
        End If


    End Sub


End Class
