One of the best ways to do this is using the GET , PUT statements
to save your window contents in an offscreen buffer. I use this in
a lot of the basic programs I wrote. After I would draw the window contents,
I would copy the window to the offscreen buffer. If an update event occurs
then you just blast the image back into the window. I works great and fast.
Its backwards to the way you should do it but until I release my Offscreen
support libraries for Quickbasic there is no other way. One problem in the
above method is that is doesn't copy color information.
