Start a Timer on a Thread

[Harry Simpson]

I've been using CF for quite a while but have not goettn into the threading
portion much at all. I've found some decent articles regarding it. My boss
asked me if I could "Start a timer on a seperate thread" and I really didn't
know what to tell him - i knew we could execute a method on a thread but
figured we could also control a timer's start event too. Is there any
reason why this could not be done in CF 2?

TIA
Harry

Hi Harry,

If you want to access a System.Windows.Forms.Timer from a thread then you
have to use Control.Invoke(). Something like this:

static void ThreadWorker() {
this.Invoke(new EventHandler(TickerStartMethod));
}

void TimerStartMethod(object sender, EventArgs e) {
// Do stuff to your Timer...
}

Use the System.Threading.Timer class. That starts a thread. A Forms timer
should only be used on the primary thread.

Harry,

just to add to what Chris said, the simple rule of thumb which is easy to
remember is; only ever use the System.Windows.Timer class within your UI
code/thread not within worker thread code and use System.Threading.Timer
otherwise.
