colored buttons

[Intel_C_Intel]

Hi,
I am trying to get 'colored' buttons according to the
code below.

1) I create a 'main' window hWnd

2) I create a number of buttons ButtonWnd(i) to move
around hWnd to different locations depending on
some calculated results

my problem is that I would like to set different colors
to the buttons instead of the gray default one.

I have tried to respond to the WM_CTLCOLORBTN message
without success.

I do not have any text on the buttons, I just use them
as push-button-like check boxes.

How do I proceed to get colored buttons?

a stripped down code snippet follows:

!main windows 
   iflag=IOR(WS_CLIPCHILDREN, & 
         IOR(WS_OVERLAPPEDWINDOW,WS_SIZEBOX))

                 lpszClassName,       & 
                 szCosTitle,          & 
                 int(iflag),          & 
                 0,                   &

                 cxWnd,               &

The best you can get is a bitmap or icon attached to the button with BS_BITMAP or BS_ICON style (see recent thread ). The feature you discovered is by design. Remarks on WM_CTLCOLORBTN in the help aren't very clear, though.
A more complicated alternative would be to use owner-draw buttons (BS_OWNERDRAW) but that would require that you do all drawing by yourself
when processing WM_DRAWITEM; (but DrawFrameControl(DFC_BUTTON, DFC_BUTTONPUSH,...) might be very helpful with that).

Documentation on WM_CTLCOLORBTN is very spotty, and would lead one to believe that this message works as described. But it doesn't; a hunt through the various archives and books turns up a comment from Petzold in his Win95 book (still valuable) that WM_CTLCOLORBTN only works with owner-draw buttons, which is of course a nonsensical and totally useless situation. Go figure. As Jugoslav has noted, making buttons with bitmaps does work, and is very easy.
