Date/Time Controls... HELP!!!

I have an SDI with multiple Views,
I have inseted 2 date/time picker controls on my resource files.
I am using a DAO database,
and MS Acess 97 what i'm working with..

here is my problem:

In VC ++ 6.0 , when i try to map the control Id's to a membe variable from my database, the Class Wizard creates this lie of code:

Code:

---

    DDX_FieldDateTimeCtrl(pDX, IDC_dateending, m_pSet->m_Ending_Date, m_pSet);

---

however, the vc++ compiler says that FieldDateTimeCtrl is an undeclared identifier.
What am I doing wrong?
HELP...
