A form can be "bound" to a table, that is, the Form's recordsource property is a table, the controlsource property for each "bound" control is a field the forementioned table. All contols on a form are not necessaarily bound to the underlying table. Merely entering data in a bound control causes it to be saved or to update the underlying table.
Forms which have only unbound controls can have that their data saved on a particular event by cycling through the form's controls with DAO or ADO code and saved in an appropriate recordset.
The first situation may be what you want.
