I need an Access application that can search dealers from my dealer list, in a
30 miles distance from the user.

You may see many applications like this on the web if you search under "find a
dealer near you". Here is one I found:
http://www.shakespeare-antennas.com/...alersearch.asp

But I do not want to have it on the web, I want to create it on access.
I think will need at least two tables:
One is a table of each of our dealers, including their zip codes.
The other one is the entire zip database whick include all zip codes in the USA
and Canada, including the lat and long for each.

Then, when the user enters the zip code of the person who wants to find a
dealer, the application will find its lat and long from the second table. It
will then "open" an area of 30 miles radius from this lat and long, and will
find all the dealers' ZIPs in that area. Actulally,
the lat and long of each.

Then it will calculate the air distance from the user ZIP codes to each of the
Dealers ZIP codes.


Answers will be appreciated.
