In the background I want to load some control after form loaded.
I tried threading but it does not allow me to add control because current
thread have not created the form.

Also please tell me what BackGroundWorker control suppose to do.

How do I do it.
Please advise me.

Thanks, Dan

Dan,
you need ot use Control.Invoke to marshal the code for creating the control
and adding it to the form to the UI thread.

In addition to the other replies, I suggest to check out the following
