In this article I will explain with an example, how to implement Timer in Windows Forms (WinForms) Application using C# and VB.Net.

Form Design

The following Form consists of a Label and a Timer control.

The Timer control has been assigned with the following properties.

Enabled – This property enables the Timer control when set to True.

Interval – The interval (delay) after which Timer will tick in milliseconds. Here it is set to 1000 milliseconds i.e. one second.

When a second changes, following event handler is executed.

Inside this event handler, every second the Timer executes its OnTick event which in turns the Label is set with the current time.

private void OnTick(object sender, EventArgs e)

{

lblTime.Text = DateTime.Now.ToString("hh:mm:ss tt");

}

VB.Net

Private Sub OnTick(sender As Object, e As EventArgs) Handles Timer1.Tick

lblTime.Text = DateTime.Now.ToString("hh:mm:ss tt")

End Sub
