The WebTimer is very similar to the desktop Timer control. The important difference is that the WebTimer is part of the page. As a result, it is controlled from the page, which is on the client side.

A WebTimer can be used to update controls on the page, for example. A regular Timer control will only execute server-side, so it cannot contact the client.


The WebTimer provides the same functionality as the Desktop Timer control. This example updates the value on a label (SecondsPassedLabel) on the web page using the WebTimer. This code in the WebTimer updates the label:

SecondsPassedLabel.Text = Str(Val(SecondsPassedLabel.Text) + 1)

You can also add a button to start and stop the timer. This code is in the Button Action event:

If Me.Caption = "Start" Then
Timer1.Mode = Timer.ModeMultiple
Me.Caption = "Stop" // button caption
SecondsPassedLabel.Text = "0"
Timer1.Mode = Timer.ModeOff // Turn off the timer
Me.Caption = "Start"
End If
