How do I access my form from a new thread?

Experts,

I have a button on my form which runs a new thread, and in this thread i'd like to update the main form controls.  Unfortunately I can't access Form.Control.Add, so I'm unsure how to get this working. I've added the code in a new thread as it causes the form to lock-up, because I'm running a while (true) loop.

Please help!

Only the main thread has access to the UI. Your thread will have to call back the main thread to do it.

Maybe you can use the BackGroundWorker component to simplify it: http://www.emoreau.com/Entries/Articles/2006/12/The-BackgroundWorker-component.aspx

all the user interfacing functions needs to be performed from the main thread
