Callback from a thread

Hello,

I have a worker thread ( a shared method in a class) that needs to callback
to another (monitoring) class on certain events. I have been unable to
figure out how to pass the callback address of a delegate in the monitoring
class to the thread. Could someone please point me to a sample or give a few
clues. I have tried to use TLS but can't figure out how to send the result
of the "address of" operator and then recover it by using SetData and
GetData.

Thanks,
Sid.

Threads can Raise Events. Just be aware that the event handler in the
monitoring class will be running in the secondary thread so it should only do thread-safe operations. If you need to access UI elements from the secondary thread or in the event handler, you will need to marshal the call back to the UI thread using the Control.Invoke method of the UI element you wish to
update.

In VS 2005, take a look at the Background worker class.
