CDocument CView CMainFrame 간 많이 쓰이는 호출 함수들
①CView::GetDocument() ②CDocument::UpdateAllViews() ③CView::OnUpdate() ④CDocument::GetNextView() ⑤CMainFrame::GetActiveView() ⑥CMainFrame::GetActiveDocument() 함수 ⑦CDC::GetSafeHdc() -> HDC를 얻는다. ⑧CWnd::GetSafeHwnd() -> HWND를 얻는다. ⑨::AfxGetInstanceHandle() -> HINSTANCE를 얻는다. ⑩::AfxGetMainWnd() -> MainFrame 윈도우 객체의 포인터를 얻는다. ⑪::AfxGetResourceHandle() -> 리소스 핸들(HINSTANCE)을 얻는다. ⑫::AfxMessageBox() -> 메시지박스를 실행한다.

메시지만 집중한 window
stdafx.h stdafx.cpp CObject.h CObject.cpp CView.h 메시지만 집중 CView.cpp MFC가 생성한 코드에 CView.h CView.cpp 만 있다고 생각해봐라. 간결함 그 자체이다.
