Hi-

I am developing a Windows application using BC++ 3.1 and
ObjectWindows.  I am having some trouble "optimizing" re-painting the
window with TScroller.

I have AutoOrg == TRUE, AutoMode = FALSE, AutoTrack = TRUE.  In my
TMyWindow::Paint routine, I can't figure out the "coordinates" of the
rectangle that needs to be repainted.  My window paints a bitmap with
Bitblt(hDC, a, b, c, d, memDC, e, f, SRCCOPY).  What should go into
the arguments a, b, c, d, e, and f?  I know it is a function of
paintInfo.rcPaint.left, ..., and the origin of the client area
viewport.

Any help or pointer to an example file that does this?

			Thanks, Ralph
