Hi ...
 
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

You can get the default color for the background of a dialog by calling GetSysColor() with the COLOR_WINDOW parameter.  That'll return you the COLORREF that you can use to create a brush. Create and select that brush before your call to Rectangle(), and your rectangle will have the correct color.

If you want a rectangle with nothing colored inside of it, you should draw a rectangle yourself by calling CDC::MoveTo() and CDC::LineTo(), or by calling CDC::Polyline or CDC::Polygon().

I don't understand your comment about "a way to delete my drawed rectangle".  If you don't want a rectangle, why did you draw it?
