 In WPF, ''Timer'' runs on a separate thread from the UI thread, so you need to use ''DispatcherTimer'' instead:
-<code xml>
+<code csharp>
-// using System.Windows.Threading;
+void ActivateTimer()
-DispatcherTimer timer = new DispatcherTimer();
+{
-timer.Interval = TimeSpan.FromSeconds(100);
+  // using System.Windows.Threading;
-timer.Tick += new EventHandler(timer_Tick);
+  DispatcherTimer timer = new DispatcherTimer();
-timer.Start();
+  timer.Interval = TimeSpan.FromSeconds(10);      // 10 seconds
+  timer.Tick += new EventHandler(timer_Tick);     // Subscribe to Tick event handler
+  timer.Start();

+void timer_Tick(object sender, EventArgs e)
