CRealTimeView * AfxGetRealTimeView( )

{

     得到文档类对象，返回CRealTimeView 类对象。

判断视图是否存在，并返回视图。

CView * CNineDoc::GetViewIfExist( CRuntimeClass *pViewClass )

{

     POSITION pos = GetFirstViewPosition( );

     CView * pView = NULL;

     while( pView = GetNextView(pos) )

         {

              return pView;

         }

     }

}

文档更新所有视图核心代码

void CDocument::UpdateAllViews(CView* pSender, LPARAM lHint, CObject* pHint)

{

     POSITION pos = GetFirstViewPosition();

     while (pos != NULL)

     {

         CView* pView = GetNextView(pos);

         pView->OnUpdate(pSender, lHint, pHint);

     }

}
