How do I detect when the user changes the color resolution?  I tried WM_DISPLAYCHANGE, but couldn't get it to work.  I also thought WM_SYSCOLORCHANGE might do the trick, but I'm not sure.

Does anybody know what I should use?

BEGIN_MESSAGE_MAP(CMyFrameWnd, CFrameWnd)
    ...
    ON_MESSAGE(WM_DISPLAYCHANGE, OnDisplayChange)
    ...
END_MESSAGE_MAP()


LRESULT CMyFrameWnd::OnDisplayChange(WPARAM wParam, LPARAM lParam)
{
    // cBitsPerPixel = wParam;
    // cxScreen = LOWORD(lParam);
    // cyScreen = HIWORD(lParam);

    return CFrameWnd::OnDisplayChange(wParam, lParam);
}
