In Paradox I could link a lookup table to a form so that if I entered the Zip
Code, the City and State name would come up. Can I do this in Access?
Sure, several ways.
One would be to use a Combo Box to select the Zip code. Include the city name
and state code in the combo's rowsource query, and either put textboxes on the
form with control sources like
=cboZip.Column(1)
to pull the second column (it's zero based), i.e. the city name, from the
combo box named cboZip; or use code in the combo box's AfterUpdate event to
"push" the city and state into the textboxes.
Note that some zip codes cover more than one city, although the USPS has a
"preferred" city name in such cases. I live in Parma (83660) and have friends
in Roswell (also 83660) and Adrian (also 83660).
