thanks Whohah,
but it won't fix my issues.
i am making an universal teleprompter, where user can load any font etc.
A. first thing, i wanted to know the possiblity to flip the RTF in one pass.

B. is it possible to capture the hidden RTB and print it on any DC.
   i tried getDC() BitBlt() where the hidden RTB is not possible to blt.
   and i tried WM_PAINT and WM_PRINT it works, but it always paint only the
  first page. (i need the actual scrolled content to be printed.)

C. i tried stretchblt() to Flip the RTF line by line in my display DC and
scroll.
   it too works well... but when user need Reverse scrolling (Top to Bottom)
   i don't know how to keep track of the Top Most line number.(Lines may
not be      equal height).

but some pro has done the job, very neatly. 5000 lines can be scrolled by
scroll bar.
(Forward or Reverse). and RTF Fliped.

pls. help me...

regards
