I'm using threadpool so I used AutoeventReset and it worked. Thank you very
much.

You use the Join method on the threads. However, there's a small.
problem: if you call Join in the UI thread, then you hang the UI.
The usual solution is to use one of the two threads as a "controller",
or use a third thread. In the first case, the second thread to be
started can be handed a reference to the first thread, and do a Join
before it signals that it's finished. If the first thread isn't
finished yet, then the second thread will wait on the Join until it is.
Therefore, when the second (controller) thread is finished, you know
that they're both finishes.
If the two threads are not logically related this way, then it might be
nicer to use a third, controller thread: the UI starts the controller,
which then starts the two worker threads. The controller then does two
Joins, one on each worker thread, and when the two Joins complete, it
signals the UI that all is done. This is scalable to an arbitrary
number of worker threads.

Thank you Christof. These 2 threads are started within a form as worker
threads only. They are coded as 2 static method within this form. The 2
threads have no form of its own. How can I then find out when they're both
done with their tasks?

Hi Pucca,
the WaitCallBack-handler (PopulateContextTable e.g.) should signal that at
the and, maybe in a finally block. If this is called from a GUI-Thread you
could call BeginInvoke on one of the Forms methods.

Hi, I'm using vs2005 and .net 2.0. I started 2 threadpool threads. How
do I
know when they're done with their tasks? Thanks.
ThreadPool.QueueUserWorkItem(new WaitCallback(PopulateContextTable));
ThreadPool.QueueUserWorkItem(new WaitCallback(PopulatAdTable));
