I made a small application using the MSVC 5 app builder (single view) and
Basically my application does only blit a bitmap to the view using bitblt.
content of the bitmap is changed I use UpdateAllViews(NULL); to update the
view. So far everything works fine.
However i got one Problem: MFC does always first draw the entire background
of the view white and then call my OnDraw code where I blit the bitmap. This
results in pretty annoying flickering, everytime the view is updated.
How do I avoid this ?
