This is a simple way how to use a personnal dialog which appears when your application uses more than one document template and you click the ‘new’ button, or during the start of the appliacation. With this You can open any document directly or by a dialog of your choice.
First time : Create variables for all the DocTemplates in the initialization of the application. The variables are used to store the instance of the pDocTemplate and used after during the FileNew process.
CWinApp header file : Add the declaration of the variables
class CCTestNoDlgApp : public CWinApp { public: CCTestNoDlgApp(); // Overrides // ClassWizard generated virtual function overrides //{{AFX_VIRTUAL(CCTestNoDlgApp) public: virtual BOOL InitInstance(); //}}AFX_VIRTUAL // Implementation //{{AFX_MSG(CCTestNoDlgApp) afx_msg void OnAppAbout(); afx_msg void OnFileNew(); //}}AFX_MSG DECLARE_MESSAGE_MAP() protected: CMultiDocTemplate* pDocTemplateFirst; CMultiDocTemplate* pDocTemplateSecond; };
In the CWinApp source file : Initialize all the variables and disable the new document dialog by setting the CcommandLineInfo to CCommandLineInfo::FileNothing. By default, the value of the CcommandLineInfo is CCommandLineInfo::FileNew and generate the document selecting dialog.
BOOL CCTestNoDlgApp::InitInstance() { AfxEnableControlContainer(); // Standard initialization // If you are not using these features and wish to reduce // the size of your final executable, you should remove // from the following the specific initialization routines // you do not need. #ifdef _AFXDLL Enable3dControls(); // Call this when using MFC in a // shared DLL #else Enable3dControlsStatic(); // Call this when linking to // MFC statically #endif // Change the registry key under which our settings are stored. // TODO: You should modify this string to be something // appropriate such as the name of your company or organization. SetRegistryKey(_T("Local AppWizard-Generated Applications")); LoadStdProfileSettings(); // Load standard INI file // options (including MRU) // Register the application's document templates. Document // templates serve as the connection between documents, // frame windows and views. pDocTemplateFirst = new CMultiDocTemplate( IDR_CTESTNTYPE, RUNTIME_CLASS(CCTestNoDlgDoc), RUNTIME_CLASS(CChildFrame), // custom MDI child frame RUNTIME_CLASS(CCTestNoDlgView)); AddDocTemplate(pDocTemplateFirst); pDocTemplateSecond = new CMultiDocTemplate( IDR_SECOND_DOC, RUNTIME_CLASS(CSecondDoc), RUNTIME_CLASS(CChildFrame), // custom MDI child frame RUNTIME_CLASS(CSecondView)); AddDocTemplate(pDocTemplateSecond); // create main MDI Frame window CMainFrame* pMainFrame = new CMainFrame; if (!pMainFrame->LoadFrame(IDR_MAINFRAME)) return FALSE; m_pMainWnd = pMainFrame; // Parse command line for standard shell commands, DDE, file open CCommandLineInfo cmdInfo; ParseCommandLine(cmdInfo); // Disable this line to reactivate the dialog selection // document on start also the dialog new document choice // appears. cmdInfo.m_nShellCommand = CCommandLineInfo::FileNothing; // Dispatch commands specified on the command line if (!ProcessShellCommand(cmdInfo)) return FALSE; // The main window has been initialized, so show and update it. pMainFrame->ShowWindow(m_nCmdShow); pMainFrame->UpdateWindow(); return TRUE; }
Now to create a new document an display the view wanted, it’s necessary to intercept the OnFileNew function, or use a fucntion by document for exemple. In the new fucntion, we can display a new personnal dialog selector, or directly select a document. In the example I’ve chosen to use the second method. The FileNew button in the toolbar is just present to show the difference between the two methods. If you don’t want to use it, just remove it.
void CCTestNoDlgApp::OnFileNewFirst() { ((CDocTemplate*)pDocTemplateFirst)->OpenDocumentFile(NULL); } void CCTestNoDlgApp::OnFileNewSecond() { ((CDocTemplate*)pDocTemplateSecond)->OpenDocumentFile(NULL); }
