Using the Dispatcher Timer

//In Dot Net Framework DispatcherTimer class is used to repeat some tasks after certain interval

//It is similar to the Timer Class used in VB 6

// Here we go

//Declare a DispatcherTimer Global Variable 

System.Windows.Threading.DispatcherTimer myDispatcherTimer;

//setup the timer- Use this code within the class constructor or any suitable place

                myDispatcherTimer = new System.Windows.Threading.DispatcherTimer();
                myDispatcherTimer.Interval = new TimeSpan(0, 0, 0, 0, 2000); // in MS 
                myDispatcherTimer.Tick += new EventHandler(Each_Tick);
                myDispatcherTimer.Start();

// event handler- place this within a class 

 public void Each_Tick(object o, EventArgs sender)
        {
            try
            {
// Code the things here that you want to happen after a certain duration 

            }

            catch (Exception ex)
            {
            }
        }
