Timer control, how to use it for a countdown.

private void timer1_Tick(object sender, EventArgs e)
{
    if(i != 0)
    {
     Answer.Visible = false;
     Feedback.Text = "Trop tard";
     timerBox.Text = Convert.ToString(i);
     i--;
    }
    else if(i == 0)
    {
    timer1.Enabled = false;
    i = 30;
    //Display whatever you want to when the timer runs out
    }
}

Actually I remember that Mike, while WOULD hang up the program. I dont have a compiler here with me at work, so I cant test this code out but Im positive Ive done it using a good ol' fashioned "tick". that was in VB though... Now I wanna see if I can remember how to do it. When I get home, C# Express, here I come!

Try this out:

/*Put this variable at the top of your class right after the namespace declaration
I put the variable "i" here because if you put it in the timer1_tick void, it
will re-instate itself to 30 when the timer intervals.*/

internal Int16 i = 30;

private void timer1_Tick(object sender, EventArgs e)
{

 /*For each tick of the timer, evaluate i and make sure it does not equal 0
 If it equals 0, time has run out (obviously :P ) and the "if" statement will
 pick it up and execute the code you want to execute when the timer is out.*/

    while(i != 0)
    {
     Answer.Visible = false;
     Feedback.Text = "Trop tard";
     timerBox.Text = Convert.ToString(i);
     i--;

     if(i = 0)
       {
       timer1.Enabled = false;
       //Any other things you want to happen or display when the time runs out
       }
    }
}

Keep in mind that I have not tested this code out in an actual compiler so you might have to tune it a bit. But its the general idea. Good luck!
