Hi,
I want to create a timer to count down from the current time to the next hour.  For example, it's format will look like this: 59:59, 59:58, 59:57... to 00:00, which I will then execute a timed method.

The problem is, I don't know how to do this.  Here's the code I've hacked up thus (removed code irrelevant to this discussion), far, but the label doesn't seem to be refreshing, so the timer being displayed is not counting down:

        private void Form1_Load(object sender, EventArgs e)
        {
            exeTimer.Interval = 1000;
            exeTimer_Tick(this, EventArgs.Empty);  
        }

        private void exeTimer_Tick(object sender, EventArgs e)
        {
            TimeSpan sp = new TimeSpan(0, 60 - DateTime.Now.Minute, 60 - DateTime.Now.Second);
            lblExecution.Text = string.Format("Time to Execution: {0}:{1:00}", sp.Minutes, sp.Seconds);
        }

I know I'm missing more code to make this complete.

Thanks.

I actually found the answer.  In my haste, I forgot to call Timer.Start().
