The Microsoft Virtual Earth service support getting driving directions to specific locations. A route can consist of a maximum of 25 waypoints.
The method VE_GetDirections() takes a List<> of SearchLocations (it will throw an exception if more than 25 objects are in the List<>). As a result it returns a RouteDirections object that holds all information about the directions. The RouteDirections.RouteLegs property contains detailed information about each direction:
RouteDirections rd = ucVEarth.VE_GetDirections(
locations, // list of waypoints along the route
true, // display the route on the map
true, // center the map for best view
VEarth.ucVEarth.RouteModeEnum.Driving, // are we walking or driving?
VEarth.ucVEarth.DistanceUnitEnum.Kilometers); // show distance in miles or kilometers?
);
lstDirections.Items.Clear();
lstDirections.Items.Add(String.Format("Total distance: {0}", rd.TotalDistance));
lstDirections.Items.Add(String.Format("Total duration: {0}", rd.TotalDuration));
lstDirections.Items.Add("");
// Iterate through all route parts
foreach(RouteLeg rl in rd.RouteLegs)
{
lstDirections.Items.Add(String.Format("{0} - {1} - {2}", rl.Description, rl.Distance, rl.Duration));
}
The list of SearchLocation objects can contain both SearchLocation objects with set Latitude and Longitude properties and objects with the Where or What property set.
