            InitializeComponent();
        }
 
        System.Windows.Threading.DispatcherTimer timer = new System.Windows.Threading.DispatcherTimer();
        private void button1_Click(object sender, RoutedEventArgs e)
        {
 
            timer.Interval = new TimeSpan(0, 0, 1);
            timer.Tick += new EventHandler(tickTime);
            timer.Start();
            popup1.Margin = new Thickness(-50, -100, 0, 0);
