• CWinApp

• 메인프레임 윈도우
  CWnd* AfxGetMainWnd();
• 뷰에서 도큐먼트
  Document* CView::GetDocument();
• 뷰에서 뷰를 둘러싸고 있는 프레임윈도우
  CFrameWnd* CWnd::GetParentFrame();
• 도큐먼트에서 뷰
  POSITION pos = GetFirstViewPosition();

• 도큐먼트에서 프레임 윈도우
  단일 도큐먼트: AfxGetMainWnd();
  다중 도큐먼트: 도큐먼트에서 뷰를 얻고 그뷰에서 자신을 포함하는 프레임 윈도우
• 프레임 윈도우에서 뷰
  CView* CFrameWnd::GetActiveView();
• 프레임 윈도우에서 도큐먼트
  virtual CDocument* CFrameWnd::GetActiveDocument();
