Question

the code below works in Windows Phone 7

    private void ShowTime()
    {
        txtTime.Text = get24hour();

        //display the Date and week.
        DateTime nowtime = DateTime.Now;
        txtWeek.Text = nowtime.DayOfWeek.ToString();
        txtDate.Text = nowtime.Date.ToString("MM/dd");   

        //create timer to fresh to time
        DispatcherTimer timer = new DispatcherTimer();
        timer.Interval = TimeSpan.FromMinutes(1);
        timer.Tick += timer_Ticker;
        timer.Start();        
    }

    private void timer_Ticker(object sender, EventArgs e)
    {
        txtTime.Text = get24hour();
    }

    private string get24hour()
    {
        return DateTime.Now.ToString("HH:mm");
    }

but error in WinRT (Metro)

error part:

  timer.Tick += timer_Ticker;

error message:

  No overload for 'timer_Ticker' matches delegate 'System.EventHandler<object>' 

what I do
I try to change the code to

    private void timer_Ticker()
    {
        txtTime.Text = get24hour();
    }

result
but it is not work again, why and how to solve it? 🙁

Answer 1

timer.Tick += new EventHandler<object>(timer_Tick); 

private void timer_Tick(object sender, object e)
{
}
