The HCB does not update if you hover over symbols that are declared inside MFC's Wizard Code markers: //{{AFX_DATA(SubTotalsDlg)
enum { IDD = IDD_SUBTOTALS };
MyListCtrl m_listctrlSubTotals;
//}}AFX_DATA
//{{AFX_VIRTUAL(SubTotalsDlg)
protected:
virtual void DoDataExchange(CDataExchange* pDX);
//}}AFX_VIRTUAL
It works fine for symbols declared outside these markers...
