      两种方法:                                                                  
        (1) SDK函数 SHGetFileInfo 或使用 ExtractIcon获得图标资源的 handle,       
        (2) SDK函数 SHGetFileInfo获得有关文件的 很多信息,如大小图标,属性,        
           类型等.                                                               
          Example(1): 在程序窗口左上角显示 NotePad图标.                          
           void CSampleView: OnDraw(CDC * pDC)                                   
             {                                                                   
                if( :: SHGetFileInfo(_T("c:\\pwin95\\notepad.exe"),0,            
                     &stFileInfo,sizeof(stFileInfo),SHGFI_ICON))                 
                   {                                                             
                     pDC ->DrawIcon(10,10,stFileInfo.hIcon);                     
                   }                                                             
              }                                                                  
            Example(2):同样功能,Use ExtractIcon Function                         
                                                                                 
            void CSampleView:: OnDraw(CDC *pDC)                                  
              {                                                                  
                HICON hIcon=:: ExtractIcon(AfxGetInstanceHandle(),_T             
                 ("NotePad.exe"),0);                                             
                                                                                 
                if (hIcon &&hIcon!=(HICON)-1)                                    
                   pDC->DrawIcon(10,10,hIcon);                                   
                }                                                                
   说明: 获得notepad.exe的路径正规上来说用GetWindowsDirectory 函数得到,          
      如果是调用 win95下的画笔，应该用访问注册表的方法获得其路径，要作成一       
个                                                                               
     比较考究的程序，考虑应该全面点.
