Question

what i want to do is pause a video after every 10s
the video should pause after ever 10s till the video ends

the code given below gives unexpected results
the video pauses fine for the firs time (i.e after 10s)
but when i play again it should pause after 10s but in my case it pauses randomly sometimes at 8s,3s 5s and etc
what should i do??
please help
thanks!!

void PlayClick(object sender, EventArgs e)
{
             VideoControl.Play();
            var dispatcherTimer = new System.Windows.Threading.DispatcherTimer();
            dispatcherTimer.Tick += new EventHandler(dispatcherTimer_Tick);
            dispatcherTimer.Interval = new TimeSpan(0, 0, 10);
            dispatcherTimer.Start();
 }

 private void dispatcherTimer_Tick(object sender, EventArgs e)
        {

            VideoControl.Pause();
        }

Answer 1

1. Add this in your dispatcherTimer_Tick-Method:

   dispatcherTimer.Stop();
   

2. Move the following part into the constructor:

   dispatcherTimer = new System.Windows.Threading.DispatcherTimer();
   dispatcherTimer.Tick += new EventHandler(dispatcherTimer_Tick);
   dispatcherTimer.Interval = new TimeSpan(0, 0, 10);
   

3. Make the DispatcherTimer a global variable.

EDIT: Thats how it should look like:

    class MyClass
    {
        private DispatcherTimer _dispatcherTimer; //now your dispatcherTimer is accessible everywhere in this class

        public MyClass()
        {
            _dispatcherTimer = new DispatcherTimer();
            _dispatcherTimer.Tick += new EventHandler(dispatcherTimer_Tick);
            _dispatcherTimer.Interval = new TimeSpan(0, 0, 10);
        }

        void PlayClick(object sender, EventArgs e)
        {
            VideoControl.Play();
            _dispatcherTimer.Start();
        }

        void dispatcherTimer_Tick(object Sender, EventArgs e)
        {
            _dispatcherTimer.Stop();
            VideoControl.Pause();
        }
    }
