Graphics with StretchBlt

[jensmaster]

I am disgning a menu wich needs to be rolled up and
down. This works fine... but once rolled down i cannot
reset the bitmap handle so the rolled down section remains
visible. I tried to use the 'ResetDC' function... did not work.

How to do this?

You have to drow the bitmap whenever it screen area is invalidated.
