update()
hi, i am using dd 1.07.
i just want to have a preview of a dwg in a control (like a button), but when i call odgsdevice::update(), the dwg is drawn in my control but also in the parent dialog.
i know that odgsdevice::update(odgsdcrect* prect) doesn't work whith a known rectangle, but how can i do to draw only in my button ?
