can't c "m_pSet" in Member Variables

Question

I am trying to associate the controls with database fields. According to the book, I should be able to add them through : In the Member Variables tab of ClassWizard, Add Member Variable dialog, there should be fields in the record set in a drop-down combo box. i.e. : m_pSet-> m_SendCard m_pSet-> m_Address : : However, I see nothing there !!! I must have missed something in the earlier step so that it hasn't link to the database yet ..... So is there a way for me to link to the desired database at the current stage ??? Thanks very much !!!
