timer

Question

I want to add a timer rather than a countdown
which automatically starts when the form loads.
Starting time should be like 20 minutes and once it ends, i.e. on reaching 0 minutes, the form should terminate with a message displayed. And how do I display the countdown on the form? Please help me because i am working on electronic examination using window application in C#

Try this. Note that I've created the timer programatically rather than via the VS designer. However you'll need to add a label to the form to show the remaining time: public partial class Form1 : Form { private Timer timer; private int mins; public Form1() { InitializeComponent(); timer = new Timer(); timer.Tick += timer_Tick; timer.Interval = 1000; // 1 second say mins = 20; // 20 minutes say } DateTime startTime; // add this manually private void timer_Tick(object sender EventArgs e) { TimeSpan ts = TimeSpan.FromMinutes(mins) + (startTime - DateTime.Now); if (ts { label1.Text = 0:00; timer.Stop(); timer.Tick -= timer_Tick; MessageBox.Show(Application terminating after  + mins +  minutes); timer.Dispose(); this.Close(); } else { label1.Text = ts.ToString(@m\:ss); } } private void Form1_Load(object sender EventArgs e) { label1.Text = mins.ToString() + :00; startTime = DateTime.Now; timer.Start(); } }

Well I assume you have a method which checks the examinee's answers against the correct ones and determines a mark or grade from that. When the time elapses you'll therefore need to call this method and show the result in the MessageBox rather than what you're showing at present.

i mean the result of the examinee should display immediately the time allocated for the examination ends. i mean the result of the examinee should display immediately the time allocated for the examination ends.

Sorry I didn't follow what you want here as a message is already being displayed as soon as the timer period elapses?
