What "function" do you mean? Double buffering is a technique, not a
function.

I mean how can i draw something in sdfV1.4 using the double buffering
technique?

You create an offscreen bitmap and do all drawing to it. Override OnPaint,
and in it blit the off-screen bitmap to the Form/Control. There are a few
controls in the SDF that do this (like the RoundGauge).

I have seen these controls scource code. but i found most of them using
bitmap class. what i want is can i use bitmapex instead of bitmap..

i have tried that.. but i failed to create a graphicex class from the
bitmapex class. can u help me on that?

cheers
