GPS tracking in C# desktop app

Gooogle maps or Gmaps ( the one i used ) works with a list of points. So you have to loop and store everytime the logintute and lattitude from the device. Put them in a list.

Now you can ad a route, and route points ( listitems) . when you done that you can draw the route.

 

take a look here. Its not that hard and very understandable. btw. Gmap and google maps both work the same. althow. google changed something ( google maps not working correctly because they stopped the service, so now i'm using google location service ( wich works the same and have more options).
