[comp.windows.ms] color bitmaps

Hi, I have a program that writes some graphical info to the screen and
to a bitmap that is the same size as the screen, when I get a WM_PAINT message
I just use BitBlt to copy the bitmap to the screen, thus redrawing the screen.
Works great when using black&white bitmap, when I added colors, when I 
copy the bitmap to the screen the screen turns blank.  I suspect the 
problem is with the ROP2 code that I am using and/or the raster operation 
that controls the way BitBlt works.  I am stuck, could a kind sole give
me some pointers...

Thank you, 

gary.
