The information in this article applies to:

 - The Microsoft Foundation Classes (MFC), used with:
    - Microsoft Visual C++ for Windows, 16-bit edition, versions 1.0, 1.5, 1.51, 1.52 
    - Microsoft Visual C++, 32-bit Editions, versions 1.0, 2.0, 2.1, 2.2, 4.0

SUMMARY
=======

An application developed with the Microsoft Foundation Classes (MFC) version 2.0
or later can change the background color of its dialog boxes by calling the
SetDialogBkColor() member function in the CWinApp class.

MORE INFORMATION
================

SetDialogBkColor() requires two COLORREF values as parameters. The first
parameter specifies the dialog box background color; the second specifies the
text color for a control in a dialog box. The application calls
SetDialogBkColor() in the InitInstance() member function of the CWinApp class.
For more information on the SetDialogBkColor() function, please refer to the
"Class Library Reference Guide, Volume 1," or to the online Help file.

The application can use the RGB macro to supply the requested colors. The
following sample code demonstrates this technique:

      BOOL CTheApp::InitInstance()
      {
         TRACE("HELLO WORLD\n");

         // Change colors to red and green.
         SetDialogBkColor(RGB(192, 0, 19), RGB(19, 192, 0));

         m_pMainWnd = new CMainWindow();
         m_pMainWnd->ShowWindow(m_nCmdShow);
         m_pMainWnd->UpdateWindow();

         return TRUE;
      }

The SetDialogBkColor() function changes the colors of all dialog boxes in an
application. If each dialog box requires a different background color, process
the WM_CTLCOLOR message and return a brush that Windows can use to paint the
dialog box background.
