Answer 1

It is necessary to dig in the direction of processing the WM_ERASEBKGND message. The standard handler fills the background of the window with the BRUSH assigned to this window, in order to replace the background, you need to handle this message yourself in the dialog procedure. And be sure to return TRUE from the handler, otherwise the standard handler will continue to fill the background with the standard color.
