                                 Other view objects constructed
                                 View windows created
                                 CMyView::OnCreate called (if mapped)
                                 CDocument::OnNewDocument called
                                 CView::OnInitialUpdate called
                                    Calls CMyView::OnUpdate
                                   Initializes the view
User executes                 CMyView functions update CMyDocument
view command                  data members
                                       Call CDocument::UpdateAllViews
                                         Other views' OnUpdate functionscalled
User executes               MyDocument functions update data

                                       Other views' OnUpdate functions called
User exits application        View objects destroyed

Answer 2

上面的.个是MDI的... 下面这个是SDI的...
Application starts        CMyDocument object constructed 
                          CMyView object constructed 
                          View window created 
                          CMyView::OnCreate called (if mapped) 
                          CMyDocument::OnNewDocument called 
                          CMyView::OnInitialUpdate called                                    View object initialized
                                    View window invalidated
                                    CMyView::OnDraw called 
 
User edits data              CMyView functions update CMyDocument data members User exits application           CMyView object destroyed 
                              CMyDocument object destroyed
