L_INT LContainer_CreateExample( HWND hWnd, LContainer & lcont) 
 
{ 
   L_INT nRet; 
 
   CONTAINERMETRICS Metrics ; 
 
   /* Initiate the container handle */ 
 
   nRet = lcont.Initialize () ;  
   if(nRet != SUCCESS) 
      return nRet; 
 
   /* Create the container and attach it to its owner window */ 
 
   nRet = lcont.Create ( hWnd ) ; 
   if(nRet != SUCCESS) 
      return nRet; 
 
   nRet = lcont.IsValid ();
