when we create child controls, what is the style for accept text formats?
(i mean: '\t', '\n' and others)

unless MSDN says otherwise, controls don't work with them. You have to expand those yourself before sending text to the control.

commented: thanks +2

i see what you mean. thanks
seems that i must do the BITMAP(you will see the next thread) for show the image and text in same time ;)
