    可以调用GDIObject:: GetObject。这个函数将指定图表设备的消息写入到            
缓冲区。下例创建了几个有用的辅助函数。                                           
//Determine if font is bold.                                                     
BOOL IsFontBold (const CFont&font)                                               
{                                                                                
     LOGFONT stFont;                                                             
     font.GetObject (sizeof (LOGFONT), &stFont);                                 
     return (stFont.lfBold)? TRUE: FALSE;                                        
}                                                                                
                                                                                 
//Return the size of a bitmap.                                                   
CSize GetBitmapSize (const CBitmap&bitmap)                                       
{                                                                                
     BITMAP stBitmap;                                                            
     bitmap.GetObject (sizeof (BITMAP), &stBitmap);                              
     return CSize (stBitmap.bmWidth, stBitmap. bmHeight);                        
}                                                                                
                                                                                 
//Create a pen with the same color as a brush.                                   
BOOL CreatePenFromBrush (Cpen&pen, cost Cbrush&brush)                            
{                                                                                
     LOGBRUSH stBrush;                                                           
     brush.Getobject (sizeof (LOGBRUSH), &stBrush);                              
     return pen. Createpen (PS_SOLID, 0, stBrush.ibColor);                       
}
