Example: Let's make a small forms application that displays a message every second (every 1000 ms that is). We add two buttons (btnStart, btnStop) and a textbox (txtMain) to a form. After that we add a timer control (timTimer) by dragging the timer control onto the form. The timer control will then be represented by a small icon below, it will look like this: 

After that we alter the properties of the control and set the .Interval property to 1000ms: 

Then we take a look at the event list (by pressing the yellow flash above the properties) and we can see that there is only one event, Tick. Double click on it to open it up for editing: 

private void timTimer_Tick(object sender, EventArgs e)          {              txtMain.AppendText(string.Format("Time: {0}\n", DateTime.Now.ToLongTimeString()));            }  

Code for the event

private void btnStart_Click(object sender, EventArgs e)          {              timTimer.Enabled = true;          }    private void btnStop_Click(object sender, EventArgs e)            {              timTimer.Enabled = false;          }  

Code for the Button

 To add a toolbar to the top of your form, expand the Toolbox and locate the ToolStrip control.
