My question is quite easy
from a CDialog, i draw a rect using dc.Rectangle(&rect) , it draws it to me in white in my dialog box , it's okay
But i dunno how to delete it,
so , how could i get the backgorund color of my Cdialog
to rewrite a REct of same size at same location x,y, but not in white , but with the background color of my Cdialog ?
Or maybe is there any other way to delete my Drawed Rectangle ?
Thanx for all
