Override the Wnd::OnCtlColor Method

Override the Wnd::OnCtlColor Method For the method one of the parameter is nctlcolor

CTLCOLOR_BTN Button control
CTLCOLOR_DLG Dialog box
CTLCOLOR_EDIT Edit control
CTLCOLOR_LISTBOX List-box control
CTLCOLOR_MSGBOX Message box
CTLCOLOR_SCROLLBAR Scroll-bar control
CTLCOLOR_STATIC Static control

Knock out 't' from can't, You can if you think you can :cool:

1. Tocahge the color 0f Menu bar : use DrawItem methos 2. Initiallly changing the Color of dialog handle WM_CTLCOLOR message 3. TO change the color of Button and Edit box You ghave to derive the class from CButton and then handle WM_CTLCOLOR Also Visit: http://support.microsoft.com/kb/q132080/ Cheers "Peace of mind through Technology"

Doesn't work with a button. You have to ownerdraw.

You can do one touch setting using...

SetDialogBkColor
(
RGB(255, 0 , 0), //red background
RGB(0, 255, 0) //green foreground
);

From now on any dialog that comes up will be using the background and foreground color you specified. Call from InitInstance method of the application class. This is a member function of CWinApp.

you can use derived button and use wm_drawitem of course change owner draw in property button for background color like Nibu thomas for initially but you can use WM_PAINT and use handle dc/cedit use WM_CTLCOLOREDIT that in event wParam is handle to device context edit use HDC hdc = (HDC)wParam;_**
