CDialog

Env: WindowsXP, VC++6.00

I am trying to make a CBaseDlg based on CDialog and some child
dialogs(CChildDlg1) based on CBaseDlg.

CBaseDlg is created by ClassWizard. ClassWizard asks a ID for CBaseDlg, but
CBaseDlg doesn't correspond to any dialog.

So, how should I fix the following sources in order to pass building?

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
//BaseDlg.h
class CBaseDlg : public CDialog
{
public:
 CBaseDlg (CWnd* pParent = NULL);

 //{{AFX_DATA(CBaseDlg )
 enum { IDD = _UNKNOWN_RESOURCE_ID_ };
 //}}AFX_DATA

 //{{AFX_VIRTUAL(CBaseDlg )
 protected:
 virtual void DoDataExchange(CDataExchange* pDX);
 //}}AFX_VIRTUAL

protected:

 //{{AFX_MSG(CBaseDlg )
 //}}AFX_MSG
 DECLARE_MESSAGE_MAP()
};
//{{AFX_INSERT_LOCATION}}

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
//BaseDlg.cpp
CBaseDlg ::CBaseDlg (CWnd* pParent /*=NULL*/)
 : CDialog(CBaseDlg ::IDD, pParent)
{
 //{{AFX_DATA_INIT(CBaseDlg )
 //}}AFX_DATA_INIT
}

void CBaseDlg ::DoDataExchange(CDataExchange* pDX)
{
 CDialog::DoDataExchange(pDX);
 //{{AFX_DATA_MAP(CBaseDlg )
 //}}AFX_DATA_MAP
}

BEGIN_MESSAGE_MAP(CBaseDlg , CDialog)
 //{{AFX_MSG_MAP(CBaseDlg )
 //}}AFX_MSG_MAP
END_MESSAGE_MAP()

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
//ChildDlg.h
class CChildDlg : public CBaseDlg
{
public:
 CChildDlg(CWnd* pParent = NULL);
 //{{AFX_DATA(CChildDlg)
 enum { IDD = IDD_DIALOG1 };
 //}}AFX_DATA

 //{{AFX_VIRTUAL(CChildDlg)
 protected:
 virtual void DoDataExchange(CDataExchange* pDX);
 //}}AFX_VIRTUAL

protected:

 //{{AFX_MSG(CChildDlg)
 //}}AFX_MSG
 DECLARE_MESSAGE_MAP()
};

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
//ChildDlg.cpp
CChildDlg::CChildDlg(CWnd* pParent /*=NULL*/)
 : CDialog(CChildDlg::IDD, pParent)
{
 //{{AFX_DATA_INIT(CChildDlg)
 //}}AFX_DATA_INIT
}

void CChildDlg::DoDataExchange(CDataExchange* pDX)
{
 CDialog::DoDataExchange(pDX);
 //{{AFX_DATA_MAP(CChildDlg)
 //}}AFX_DATA_MAP
}

BEGIN_MESSAGE_MAP(CChildDlg, CBaseDlg)
 //{{AFX_MSG_MAP(CChildDlg)
 //}}AFX_MSG_MAP
END_MESSAGE_MAP()

TIA
