    诸如COleControl : : GetFortColor和COleControl : : GetBackColor等函数         
返回OLE _COLOR数据类型的颜色，而GDI对象诸如笔和刷子使用的是COLORREF数据类        
型，调用COleControl : : TranslateColor可以很容易地将OLE_COLOR类型改为            
COLORREF类型。下例创建了一个当前背景颜色的刷子：                                 
                                                                                 
void CSampleControl : : OnDraw (CDC* pdc                                         
    const Crect& rcBounds , const Crect& rcInvalid )                             
{                                                                                
    //Create a brush of the cuttent background color .                           
    CBrush brushBack (TranslateColor (GetBackColor ( ) ) );                      
                                                                                 
    //Paint the background using the current background color .                  
    pdc—> FilllRect  (rcBounds , &brushBack) ;                                  
                                                                                 
    //other drawign commands                                                     
                                                                                 
    …                                                                           
                                                                                 
}
