Hi everyone,

I need the tag that provides the zipcodes within a specified mileage , to be used as "Store Locator" . I searched a lot and found a few links, but they either don't have rating, or no reply to email, and the webmonkey link is broken (found in one of the answers, does anyone know the new link for it??).

assume we have the database in MSACCESS, which tag is reliable to use?

I would appreciate your help.

If you have a database mapping ZIP codes to geographical coordinates you don't need a tag, you need the Pythagorean theorem: a2 +b2 = c^2 This allows you to calculate the distance between ZIP codes and everything else follows from that.

thanks for the information. but instead of reinventing the wheel, I know there are some ready tags, just don't know which one is reliable. I would like a reference. I would appreciate if somone knows about it.

Rule #1:  Google is your friend

Rule #2:  CFLIB.ORG is also your friend

Google "CFLIB ZIPCODE Distance" and you get a link to
