FIX: RichEditCtrl IDs Not Shown in Member Variables Tab

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.

   // Dialog Data

      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

      virtual void DoDataExchange(CDataExchange* pDX);

      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);
   }
