Remarks

This class performs a lookup of values in a field to populate a combobox.

When you add the class to a form, Visual FoxPro opens a builder so you can specify the appropriate Lookup_table, Order_column, Display_column, and Return_column values. When you drop the class on a project, you can choose between adding the class or creating a subclass.
