Marking current location on Map

Question

Hi everyone,

  I am pretty new to Windows Phone app development, I working on a small app in which i need to display the current location of the user on the map. I tried it using following code snippet from a example.  Is there a way to get the current location coordinates ???  I heard using GPS we can get the current location lat,long values how can we get that ???

#code snippet

       {

            Geolocator myGeolocator = new Geolocator();
            Geoposition myGeoposition = await myGeolocator.GetGeopositionAsync();
            Geocoordinate myGeocoordinate = myGeoposition.Coordinate;
            GeoCoordinate myGeoCoordinate = CoordinateConverter.ConvertGeocoordinate(myGeocoordinate);

            this.mapWithMyLocation.Center = myGeoCoordinate;
            this.mapWithMyLocation.ZoomLevel = 14;


            Ellipse myCircle = new Ellipse();
            myCircle.Fill = new SolidColorBrush(Colors.Blue);
            myCircle.Height = 20;
            myCircle.Width = 20;
            myCircle.Opacity = 50;


            MapOverlay myLocationOverlay = new MapOverlay();
            myLocationOverlay.Content = myCircle;
            myLocationOverlay.PositionOrigin = new Point(0.5, 0.5);
            myLocationOverlay.GeoCoordinate = myGeoCoordinate;

            MapLayer myLocationLayer = new MapLayer();
            myLocationLayer.Add(myLocationOverlay);

            mapWithMyLocation.Layers.Add(myLocationLayer);

       }

 public static GeoCoordinate ConvertGeocoordinate(Geocoordinate geocoordinate)
        {
            return new GeoCoordinate
                (
                geocoordinate.Latitude,   
                geocoordinate.Longitude,
                geocoordinate.Altitude ?? Double.NaN,
                geocoordinate.Accuracy,
                geocoordinate.AltitudeAccuracy ?? Double.NaN,
                geocoordinate.Speed ?? Double.NaN,
                geocoordinate.Heading ?? Double.NaN
                );
        }

My actual requirement is to display the location of user on the map. If i know the latitide, langitude values I able to do It, My major problem is finding them.  

 

Any suggestion is Appreciated

Answer 2

Thanks Ken Tucker

I'v tried with the link you have given, its working. But in VS it is showing the default co-ordinates. I want to test this app on lumia 720 mobile. I've tried to side load the app but i'm unable to do it. Is there anyway to test the apps on the mobile without publishing it to the store.

Regards,
