How to implement Timer

Hi
you can use this technique

1) MouseMove - event used to check whether the screen is active or not..
2) Timer - used to check the interval of 10 mins

rest you can understand from the below code..

private void Form1_Load(object sender, EventArgs e)
       {
           t.Tick += new EventHandler(t_Tick);
           t.Start();

       }

       Timer t = new Timer() { Interval = 5000 }; //600000 for 10 minutes , 5000 for 5 seconds (testing)
       private void Form1_MouseMove(object sender, MouseEventArgs e)
       {
           t.Stop();
           this.Text = "active" + DateTime.Now.ToString(); //  testing purpose
           t.Start();

       }

       void t_Tick(object sender, EventArgs e)
       {
           MessageBox.Show("Application will exit now ");
           Application.Exit();
       }
