I am trying to make an antialias routine work
on Win9x systems, but on these systems i am
using a region to obtain the irregular window
shape needed for my application.
On Win2k/XP, i use layered windows and the
desktop is updated continuously but with the region
it is not. I need to take a snapshot of the desktop
that is behind my skin, it works but i get an image
of my window too inside it making the antialias result
pretty ugly :( ...
How can i force an update of the region underneath my
window each time i want ?
