    <p>Here is the link for the geolocation sample in Windows 8: <a href="http://code.msdn.microsoft.com/windowsapps/Geolocation-2483de66" rel="nofollow noreferrer">Windows 8 Geolocation Sample</a></p> <p>You can check the samples in C#, JavaScript, and C++. Below is the specific part where it shows the latitude and longitude in JavaScript. You can find the corresponding in C++/C# by browsing through the code samples:</p> <p><strong>JavaScript</strong></p> <pre><code>function getPositionHandler(pos) { document.getElementById('latitude').innerHTML = pos.coordinate.latitude; document.getElementById('longitude').innerHTML = pos.coordinate.longitude; document.getElementById('accuracy').innerHTML = pos.coordinate.accuracy; document.getElementById('geolocatorStatus').innerHTML = getStatusString(loc.locationStatus); } </code></pre> <p>Regarding location of Trafalgar Square, I'm sure Bing Maps API or Google Maps API, or any Maps API will help in finding the specific longitude and latitude.</p> <p>I also suggest you take a look at this StackOverflow post regarding longi/latitude: <a href="https://stackoverflow.com/questions/8914580/get-users-location-latitude-longitude-with-bing-or-google-maps-api">Link</a></p> <p>I also have given a link for a code snippet to find lat/long using Google Maps API: <a href="http://aspsnippets.com/Articles/Google-Maps-API-V3-Get-Latitude-and-Longitude-of-a-location-from-Address-using-JavaScript.aspx" rel="nofollow noreferrer">Link</a></p> <p>To parse the direction, you might have to write your own function, which shouldn't be too difficult.</p> <p>Hope this helps in your app development!</p> <p><strong>Edit</strong>: I have also attached two links for determining distance and bearing with two latitudes. They are both pretty much the same: <a href="http://www.yourhomenow.com/house/haversine.html" rel="nofollow noreferrer">Link 1</a>, <a href="http://www.movable-type.co.uk/scripts/latlong.html" rel="nofollow noreferrer">Link 2</a>. They explain the concepts very well.</p> <p><strong>Second Edit</strong>: Did you catch your pun? >> <em>How on <strong>earth</strong> do I get access to the tablet's location to then calculate where it is, relative to that location?</em></p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
