Have a read of these

Backgroundworker thread example[^]

CP: Introduction to threading[^]

Personally I prefer to use Backgroundworker on a form as I am able easily to update the progress of the backgroundworker to the UI.

I have triyed Backgroundworker thread example[^] but it is of no use. Because this is giving me error as "Cross-thread operation not valid: Control 'Lbl_Status' accessed from a thread other than the thread it was created on" Please help

You need to use invoke and delegates to gain access to the ui control with either threads or background worker
