Calculate Driving Distance Between 2 Coordinates

[fbcma]

I am using Access 2013 and am developing a form where the user provides two coordinates.
And the form will calculate the driving distance between these 2 coordinates.
I'm not sure where to start. Any input/sample would be greatly appreciated. Thanks.

Geometry would give you the distance between 2 points, but you want driving distance which is going to require a map. I'd check out the google map API:

Google Maps Platform Documentation | Google for Developers

Documentation and code samples for Google Maps Platform APIs and SDKs.

developers.google.com

I've only done a cursory google search ('driving distance in google map api'), but it looks like others have tried to tackle this.

What about Bing API?

Sure.

calculate the driving distance between 2 zip codes

I import information pertaining to a shipment. I have to calculate the driving distance between 2 zip codes. Currently I go to mapquest, enter the two zip codes, then paste the distance within my DB. I've looked at applications that calculate the distance, but they do not calculate driving...

You can also 'cheat' by using a form which loads the Google (or Bing) route planner map for the two sets of co-ordinates entered.
This is a screenshot from one of my apps which does that using postcodes rather than coordinates, but the principle is the same.

That code @Gasman has posted worked really well for UK postcodes in an app I used about 8 years ago, kudos to @jdraw
