Threading Join issue - getting Join_Timeout Exception.

Hi all,

I have an application that creates an object which creates a thread in its constructor. The application then starts this threads by calling the Start() property on this object, and then calls a Thread.Sleep(), and then the Stop property to stop the Thread() - and example of the code is below..with the issue I am getting provided below.

static void Main()
{
PowerNotifications pn = new PowerNotifications();
pn.Start();
Thread.Sleep(10000);
pn.Stop();
}

public class PowerNotifications
{
public PowerNotifications()
{
t = new Thread(new ThreadStart(DoWork));
}

public void Start()
{
t.Start();
}

public void Stop()
{
done = true;
t.Abort();
}

private void DoWork()
{
// Do some execution...
t.Join(20000);
}
}

Now my problem is this. Because the time passed into the Join method is greater (20000) than the Thread.Sleep(10000) I get a Join_Timeout exception. But if I remove the Thread.Sleep(10000) the application doesn't hold up for the time specified in the Join(20000) call. I deally, I don't want to specify a time in the Thread.Sleep() call (or even specify it at all) because I simply don't know how long the thread (t in this case) will be executing for.

How do I solve this

(if you feel I haven't explained myself well enough, please state so, and I will try to clarify things)

Thanks
