Bind a hyperlink to the value of a field. I believe that you could
just programmatically set the HyperLinkAddress property of many
controls.. by just setting it on the form_current event.
Arvin Meyer has a great answer to "Open Map Quest from a Form" under
Microsoft Access Forms. His detail code set me up in minutes. I can click on
a command button that uses the postal code on the form to bring up the map in
Map Quest without having to type anything in the Map Quest page.
