I am using BitBlt to draw a picture. I am having some probs...

1) However, when the form on which the picture is drawn is moved, resized, minimized, etc. the picture is erased. How do I prevent this happening?

2)If I move another form over my 'front' picbox, some of the picture is erased, since I can't set AutoRedraw to True.
How can I make this picture 'redraw' even when this form doesn't have focus, to prevent this problem?

Thanks.
