Hi,
I have a small windows form. This has 2 labels and a button. When a
user presses a button, I copy a large file. Nowwhen the copy is going
on, if I switch windows, my main window becomes white. How can I retain
the values of the screen when switching between the windows?
Thanks.

You can copy asynchronously or in separate thread

Well that make sense. But I remember reading (I think it was game
programming in c#) that there is a method that get invoked every time
the windows switch happen or something or repaint and all you have to
do is repaint all the elements, I am not sure. Well, I will search, if
nothing work out I will take the async approach.
Thanks.

The thread is probably the preferred method but if you are copying chunks at
a time using a filestream you can just put an Application.DoEvents in there.

Well, the method which gets invoked when you swith windows is form.activate/form.deactivate which
you can wire and call Invalidate() on the form. I doubt it would help you as copying might involve
lots of resources. I would go for a async copying.
Thank you
