Running clock

Question

Hi All,

 I basically want a form to load and have a label that displays the running time as HH:MM:SS and it should be a running clock. The seconds should actually be moving. (not just display the current time)

How to do this?

Thanks,

Amit

Answer 1

Hi,

use a windows timer component, and in the timer event, update the label's text property with the current time (datetime.now).

set the interval to 1000 ms, and if you want to format the date to a particular format, use 'somedate.ToString(somecustomformatstring)'

for custom datetime formatstrings, see http://msdn.microsoft.com/en-us/library/8kb3ddd4.aspx

Create a new Windows Form Application

Add a label control to it

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
  public partial class Form1 : Form
  {
    public Form1()
    {
      InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
      Timer clockTimer = new Timer();
      clockTimer.Enabled = true;
      clockTimer.Interval = 1000;
      clockTimer.Tick += new EventHandler(clockTimer_Tick);
    }

    void clockTimer_Tick(object sender, EventArgs e)
    {
      this.label1.Text = DateTime.Now.ToString("hh:mm:ss");
    }
  }
}

There's probably some Whizzo control out there that will do this and a million and one other things besides, but the basics to Do It Yourself are:

A Timer that 'ticks' every second (1000 milliseconds), and

A Label in which to display the formatted time.

private void Timer1_Tick( object sender, EventArgs e ) 
{ 
  this.Label2.Text = DateTime.Now.ToString( "HH:mm:ss" ); 
}

No..

I want to start the timer as 00:00:00

DateTime.Now shows me the current time.

Thanks

Answer 7

create a form level variable and assign it the current time. In the timer tick, subtract that time from the current time, and use that to assing to the label's text.

This is a timer which starts from zero, and on (you can add hours and what ever you want to it):

    System.Windows.Forms.Timer timer2;
    TimeSpan ts = new TimeSpan();
    public Form1()
    {
      InitializeComponent();
      label1.Text = "";
      //timer2:
      timer2 = new Timer();
      timer2.Tick += new EventHandler(timer2_Tick);
      timer2.Interval = 1000;
      timer2.Start();
    }

    private void timer2_Tick(object sender, EventArgs e)
    {
      ts = ts.Add(TimeSpan.FromSeconds(1));
      label1.Text = String.Format("minutes:{0}, seconds:{1}",ts.Minutes, ts.Seconds);
    }
