Seems like we've had this discussion in this group before. Have you checked
the archives?

The pattern goes something like this:

-----

// This event will be set when you want the thread to exit.
protected AutoResetEvent thev = new AutoResetEvent( false );

startbutton_click()
{
th = new Thread( new ThreadStart( this.MyThread ) );
th.Start();
}

protected virtual void AcqThread()
{
while (thev.WaitOne(time, false) == false)
{
}

// The event was set. Time to exit the thread...
}

stopbutton_click()
{
thev.Set();

th.Join(waittime);
}

That's what happens when you copy/paste bits and pieces, but not the whole
program... Substitute the pieces below in your thinking:

-----

protected virtual void MyThread() // Helps to set the name right!
{
while (thev.WaitOne(time, false) == false)
{
// Do whatever processing you need here. This code will be executed
every 'time'
// milliseconds. So, if you want it to happen every 30s, set time
to 30000.
}

// The event was set. Time to exit the thread...
}

----

Note that you should *always* indicate what version of .NET CF you're
talking about. The code has to be written a *lot* differently for .NET CF
1.0 and 3.5...

I don't mean you and I, personally. The archives of the group contain a
wealth of information, if you don't treat the group as a chat and, instead,
look to the archives *before* asking a question.

Why can't you use the Threading.Timer class? this will execute on a separate
thread which essentially adds the request to the thread pool for you
automagically.

I would simply create a timer for this, and have the timer event
create a background thread and go off and do its work. Then the
Start/Stop button would just Enable/Disable the timer.

Depending on exactly what you need to do, it may not work for you, but
it works for my situation.
