if yes pls provide me some sample, newbie to threading....

It depends what you do during the Excel creation.

A very simple and effective way to create and control a background thread is using a BackgroundWorker.

It very easy to implement.

And it's thread safe

You can find a working example I've prepared (BackgroundWorkerDoStuff).
