Setting the background color of Static Text item and window

 Setting the background color of Static Text item and window While designing ATL forms, I've encountered this problem, which seems
trivial at first glace.
I trying to make a the background of a static text transparent, or
paint it with a specific color (the form's background color), other
than the default gray.
I need this because I'm creating a form with a specific background
color. Actually, I couldn't find a way to do this other than creating
a huge bitmap (CreateCompatibleBitmap) and painting it with a
Rectangle of the same size.
I tried subclassing the WinProc (using SetWindowLong) so as to catch
and handle the WM_CTLCOLORSTATIC event, but it doesn't help - the
item's background is still gray. The same treatment _does_ work for
List Boxes using WM_CTLCOLORLISTBOX - which gets me to believe that
it's an ATL bug in Static Text.
Any idea? Also, I'll be glad to hear any idea regarding a simpler way
to set the window's background color.

Setting the background color of Static Text item and window Can you add REFLECT_NOTIFICATIONS() macro and handle OCM_BASE +
WM_CTLCOLORSTATIC (??) Of course, You will have to check the handle (from
lparam).. Use the wParam (which is the HDC to set the background color
SettBkColor() .. It might help..

Setting the background color of Static Text item and window SetBkColor won't work. One has to return a brush handle of proper color in
response to WM_CTLCOLOR* messages. SetTextColor does work if you want to
change the font color.

Setting the background color of Static Text item and window You are right. It does not work!! But, If you handle the WM_CTLCOLOR on the
dialog window itself, it might work. It does work for MFC.. I cant see why
it should not work for ATL..

Setting the background color of Static Text item and window You may be able to subclass it and handle the WM_ERASEBKGND message explicitly... I haven't actually tried it myself... --

Igor, as I mentioned in the original posting, WM_CTLCOLOR* doesn't work for Static Text. Girish, I didn't try to handle the WM_CTLCOLOR of the dialog window
itself. Worth the try. Thanks.

Setting the background color of Static Text item and window WM_CTLCOLOR* is sent to the parent window of the control (as is plainly
stated in the documentation). You tried to handle it by subclassing the
control, which was a wrong thing to do. Handle it in the dailog window.
