BUG: RichEditCtrl IDs Not Shown in Member Variables Tab

Last reviewed: June 16, 1997
Article ID: Q165744
The information in this article applies to:
  • The ClassWizard included with: - Microsoft Visual C++, 32-bit Editions, version 5.0

SYMPTOMS

The Member Variables tab in the ClassWizard does not show the IDs for Rich Edit controls.

This is not a problem in the Message Maps tab of ClassWizard.

RESOLUTION

To work around this problem, you need to add the member variables for the Rich Edit control manually to the class definition in the dialog class and associate it with the control.

  1. Add the correct type of member variable to the dialog class.

  2. Add DDX_ and/or DDV_ function calls to the dialog's DoDataExchange().

The following code snippet associates:
  • A CString data member (m_richedit) with the rich edit control and validation code so that max length of text in the control is not greater than 10 characters.
  • A control variable (m_richEditCtrl) of type CRichEditCtrl with the rich edit control.

-- sampledlg.h --

   class CSampleDlg : public CDialog
   {
   public:
      CSampleDlg(CWnd* pParent = NULL);

   // Dialog Data
      //{{AFX_DATA(CSampleDlg)
      enum { IDD = IDD_SAMPLE_DIALOG };
      CString  m_edit;      // Added by ClassWizard for an edit control
      //}}AFX_DATA

   // Manually add member variables for the rich edit control
      CRichEditCtrl m_richEditCtrl;

      CString m_richedit;

      // ClassWizard generated virtual function overrides
      //{{AFX_VIRTUAL(CSampleDlg)
      protected:
      virtual void DoDataExchange(CDataExchange* pDX);
           // DDX/DDV support
      //}}AFX_VIRTUAL

           ......

      DECLARE_MESSAGE_MAP()
   };

-- sampledlg.cpp --

   ......

   void CSampleDlg::DoDataExchange(CDataExchange* pDX)
   {
      CDialog::DoDataExchange(pDX);
      //{{AFX_DATA_MAP(CSampleDlg)
      DDX_Text(pDX, IDC_EDIT, m_edit);
      DDV_MaxChars(pDX, m_edit, 10);
      //}}AFX_DATA_MAP

   // Manually add DDX_Control, DDX_Text and DDV_MaxChars for the
   // rich edit control
      DDX_Control(pDX, IDC_RICHEDIT1, m_richEditCtrl);

      DDX_Text(pDX, IDC_RICHEDIT1, m_richedit);
      DDV_MaxChars(pDX, m_richedit, 10);
   }

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this bug and will post new information here in the Microsoft Knowledge Base as it becomes available.

Steps to Reproduce Behavior

The following steps can be used to reproduce the problem.

  1. Create an AppWizard0generated MFC application that uses dialog resources.

  2. Open the Resource Editor to add a Rich Edit control to that dialog template.

  3. Open the ClassWizard and go to the "Member Variables" tab. Try to add a data member for the control.

  4. The Rich Edit control ID is not shown in the ClassWizard.
