Your question is not clear. A form is part of the database, so making a
change in a form is making a change in a database. However, if what you're
asking is, can you make a change to a value in a control on a form without
changing the value in a field in a table, that depends...if the control on
the form is bound to that field in that table, then any change in the
control's value will change the value in the field, unless you use code to
cancel the updating of that value.
If you want to make changes in a control without affecting fields' values,
then you can use unbound controls on forms, and use code/macro to populate
those controls with values so that they are displayed.
In other words, to give you a better answer, you need to provide us with
more information!
