form button doesn't work with threads!

[kadamora]

I'm making my first program that is using threads...the problem is that when I click the button that I created in windows form it never goes to the button click event in the debuger!!!
I've read that that those threads should be background so i made like this

Thread sendcon = new Thread(new ParameterizedThreadStart(sending));
                sendcon.IsBackground = true;                
                sendcon.Start(SendingStream);

is there any way to make sure that the event could be done while another threads are working???

Use BackgroundWorker class.
