Hello Thomas Thanks for replyng Actually problem is that, i want to store the image of picture box in a object so that when it gets repainted because of minimization of picture box or any other window comes above it. So that it will reduce the time to redraw it. And one more thing to tell that while drawing in the picture box, there are near about 400000 points. and because of that its taking so much time. Regards Avinash Patil avinashpatil3484@gmail.com
