// 修改了原始的文档

                            SetDefaultTitle(pDocument);



                            if (!pDocument->OnNewDocument())

                            {

                                   TRACE0("Error: OnNewDocument failed after trying to open a document - trying to continue.\n");

              pDocument->SetPathName(lpszPathName);

       CWinThread* pThread = AfxGetThread();

       if (bCreated && pThread->m_pMainWnd == NULL)

}

以下是多文档模板的OpenDocumentFile的实现

CDocument* CMultiDocTemplate::OpenDocumentFile(LPCTSTR lpszPathName,

       BOOL bMakeVisible)

{

       //新建一个文档对象

       CDocument* pDocument = CreateNewDocument();

……



       BOOL bAutoDelete = pDocument->m_bAutoDelete;

       pDocument->m_bAutoDelete = FALSE;   

       CFrameWnd* pFrame = CreateNewFrame(pDocument, NULL);

       pDocument
