I would like to write codes for a timer control system on WebForm.aspx. The timer control system allows users enter a specific time (such as 8pm) or a timer interval (such as 8pm - 6am) to trigger some actions. May I know how to implement this timer control system in WebForm.aspx?

Thanks

You can use Timer class of System.Timers
You can just drag the timer control from the toolbox(components tab) on to your webform designer

Hi Ester,

Another sample on that image I did send you.
Using the timer on the server side has no sence in my opinion.
(This is not a production sample, the sending of the image is in my opinion
to slow, however I never tested it over the net and maybe making from it a
thumbnail first will than help, however I doubt it).

The timer part is in Form1

I hope this helps?
