添加模板

在復寫的CWinApp::InitInstance()函數中添加下面代碼

CMultiDocTemplate* pDocTemplate; pDocTemplate = new CMultiDocTemplate(IDR_SMARTTTYPE,RUNTIME_CLASS(CCosiWorksDoc),RUNTIME_CLASS(CChildFrame), // custom MDI child frameRUNTIME_CLASS(CCosiWorksView)); AddDocTemplate(pDocTemplate);new一個CMultiDocTemplate，并用doc,frame,view的CRuntimeClass類初始化CMultiDocTemplate

然后調用AddDocTemplate，往CWinApp的成員m_pDocManager變量，文檔管理器中添加模板

void CWinApp::AddDocTemplate(CDocTemplate* pTemplate) {if (m_pDocManager == NULL)m_pDocManager = new CDocManager;m_pDocManager->AddDocTemplate(pTemplate); }打開文檔
CDocument* CWinApp::OpenDocumentFile(LPCTSTR lpszFileName) {ENSURE_VALID(m_pDocManager);return m_pDocManager->OpenDocumentFile(lpszFileName); }CDocument* CDocManager::OpenDocumentFile(LPCTSTR lpszFileName) {POSITION pos = m_templateList.GetHeadPosition();CDocTemplate* pBestTemplate = NULL;while (pos != NULL){CDocTemplate* pTemplate = (CDocTemplate*)m_templateList.GetNext(pos);CDocTemplate::Confidence match;match = pTemplate->MatchDocType(szPath, pOpenDocument);if (match > bestMatch){bestMatch = match;pBestTemplate = pTemplate;}if (match == CDocTemplate::yesAlreadyOpen)break; // stop here}return pBestTemplate->OpenDocumentFile(szPath);}CDocument* CMultiDocTemplate::OpenDocumentFile(LPCTSTR lpszPathName,BOOL bMakeVisible) {CDocument* pDocument = CreateNewDocument(); }CDocument* CDocTemplate::CreateNewDocument() {CDocument* pDocument = (CDocument*)m_pDocClass->CreateObject();return pDocument; }void CMultiDocTemplate::AddDocument(CDocument* pDoc) {ASSERT_VALID(pDoc);CDocTemplate::AddDocument(pDoc);ASSERT(m_docList.Find(pDoc, NULL) == NULL); // must not be in listm_docList.AddTail(pDoc); }CDocument* CMultiDocTemplate::OpenDocumentFile(LPCTSTR lpszPathName,BOOL bMakeVisible) {CDocument* pDocument = CreateNewDocument();CFrameWnd* pFrame = CreateNewFrame(pDocument, NULL); }CFrameWnd* CDocTemplate::CreateNewFrame(CDocument* pDoc, CFrameWnd* pOther) {CFrameWnd* pFrame = (CFrameWnd*)m_pFrameClass->CreateObject(); }CDocument* CMultiDocTemplate::OpenDocumentFile(LPCTSTR lpszPathName,BOOL bMakeVisible) {CDocument* pDocument = CreateNewDocument();CFrameWnd* pFrame = CreateNewFrame(pDocument, NULL);pDocument->OnOpenDocument(lpszPathName); }到這里調用到了CMultiDocTemplate中實際的文檔里，就是RUNTIME_CLASS(CCosiWorksDoc)
