Version 2.9 22/04/2019
This utility can be used to determine your current geolocation in Access.
The attached zip file contains an Access file and 4 other items.
Each of these needs to be saved to the same folder

The geolocation code & map requires the use of a free Google Maps API key.
You can obtain your own free API key from https://cloud.google.com/maps-platform.
Google now requires billing information to be entered when obtaining API keys.
However there is a fairly generous monthly free allowance & small/medium users of Google Map APIs should still be able to download various maps without incurring charges
Click any image to view a larger version ...
Once you have entered a valid API key, click 'Get Current Location' on the main form.
A browser window will open and ask permission to obtain your location.
Click the 'Allow Once' button within 3 seconds to do so
Your current location should be shown on the map & your latitude / longitude displayed.
The browser window will then close & the geolocation data shown in Access together with a static map centred on that. The map can be nudged or zoomed as required.
Reverse geocoding is also used to obtain a shortened address for the location which should be accurate to within a few metres.
If you don't click the button in time, you will be offered further 'chances' to do so
The example database was created in Access 2010 32-bit and Windows 10.
However, it has been successfully used in all versions of Access from 2007 through to 2016 (both 32-bit & 64-bit). It works in any version of Windows from Win7 SP1 onwards (but see point 3 below)
There are some caveats:
1. You must switch on location services in Windows settings / Control Panel
2. Your computer must contain a geosensor (all tablets / many laptops / not many desktops)
3. There is a bug affecting Internet Explorer in the Windows 10 1803 update.
The browser window will report "Error - the geolocation service failed"
It doesn't matter which browser is your default, IE is always used by Access for browser related code.
I reported this bug to Microsoft in May 2018 and a fix was released for the 12 June update - KB4284835.
However I have found the fix doesn't work on all computers. MS have again been informed
Windows 10 version 1809 update seems to have fixed the issue for most computers(but not all)
4. The form includes an ActiveX slider control - this will not work if you have disabled ActiveX completely in Access settings
If you cannot get your location for any of the above reasons (or to do this for another location), you can obtain latitude & longitude data in other ways e.g.
a) Open Google maps to your current location
b) Use GPS data from a mobile phone or other device with a geosensor
c) Use a Windows app such as Sensor List or Geolocator (free from the Windows Store)
d) Take a photo using your PC webcam then use the GPS data from the photo properties
Enter the values on the form then click 'Search'
An enhanced version of this utility is included in the UK Postal Address Finder application
It is used to locate the nearest postcodes for the current location (or any other geolocation).
That info is then used to find nearby places within a specified radius e.g. restaurants within 500 metres
