If a date/time field has a format defined in the main table - is it
nessessary to define it again in the form control?
is it efficient? (Re-Formatting all dates on a form)
If the field has been added to the form from the Field List tool
button, it will retain whatever formatting is set up in the table
field.
If you then subsequently change the table field formatting, the
existing control format will not change. To get the new formatting,
either change the control formatting or delete that control and re-add
a new one from the Field List tool button.
Remember though, the field format in the table really doesn't matter,
as you should always be entering, viewing, and manipulating your data
through a form, query or report.
