David,
Under Tools, Options, Field Mapping you can set the generic set of classes to use by default for each type of table field. If the table is in a VFP database you can set individual fields to a specific control class also.
>I am new to VFP. I have created a test form and have added tables to the DE. When I drag fields from the tables onto the form,it uses the standard textbox baseclass. How do I get field to use the textbox class from the my own class library, which is the active toolbar, when dragging fields form the tables onto the form.?
