Timers in a Windows Service
I have a fairly simple windows service I've designed, but after deploying it I found it wasn't working. After a bit of messing about I got remote debugging working, and found that the reason was that the timer wasn't ticking. I created a new service, which would write to a text file on every timer tick (once every 60,000 milliseconds, or 1 minute), and this doesn't work either.

Now the timer.enabled property defaults to false, but in the OnStart sub I set it to true and again in the OnStop I set it to false. The timer is definitely enabled, because I also put Pause and Continue routines in the first service and when stepping though these, the timer.enabled property does change (and is set to true when exiting the Continue routine).

Anyone else encountered a similar problem?

Hi there,

Did you also start the timer? e.g.:


I think this method is new in .NET. In classic VB, setting it to enabled meant it would start automatically (at least I think that was the case), but in the .NET world you have to start it yourself.

Nope, realised that I was using a System.Windows.Forms.Timer rather than a System.Timers.Timer (how stupid of me!). I can't really understand why the dot net designers thought having two timer classes that both perform in almost identical ways was a good idea, but what do I know...
