Creating a Recordset for the Course Table
Enroll currently has one recordset, for the Section table. This recordset fills the controls on the CSectionForm record view with information about a single class section of the currently selected course name. Now you will add a second recordset, for the Course table, used to fill the combo box control with a list of all available course names.
