sir,
Thank you very much. It is working well. Now I got the point. I was creating an instance of the window everytime I click the button. But here I got a doubt. We are creating the instance of the findbox in the application even before clicking it. Now for any reason if we donot click the button , doesn't that cause memory wastage? Kindly rectify my doubt.

Thanks once again for this useful post,
Sarma.
