vc Static背景 颜色

处理   WM_CTLCOLOR   消息

HBRUSH   CAboutDlg::OnCtlColor(CDC*   pDC,   CWnd*   pWnd,   UINT   nCtlColor)  
{
        HBRUSH   hbr   =   CDialog::OnCtlColor(pDC,   pWnd,   nCtlColor);

        if   (nCtlColor==CTLCOLOR_STATIC)      
        {
                pDC-> SetBkMode(TRANSPARENT);
                return   m_backHbrush;
        }
        return   hbr;
}
m_backHbrush定义为成员变量,HBRUSH类型,在OnInitDialog中初始化:
m_backHbrush=CreateSolidBrush(RGB(0,255,255));
