How to use BingGeocodeProvider ?

[Sebastian Talamoni]

Hi,

I am trying to use the GeoCodeAsync to find the Location of a given address.

I get a response == Success but NO result results ( e.Response.Results == 0 )

Doing the same from the Bing webpage works fine (finds the address and shows the map).

   private void Button_Click(object sender, RoutedEventArgs e)
        {

            var bing = new BingGeocodeProvider { MapControl = RadMap1 };
            bing.ApplicationId = BingMapHelper.VEKey ;
            bing.GeocodeCompleted += bing_GeocodeCompleted;

            var address = new Address { AddressLine = addressLine.Text };
            var request = new GeocodeRequest { Address = address };
            bing.GeocodeAsync(request);
        }

        void bing_GeocodeCompleted(object sender, GeocodeCompletedEventArgs e)
        {
            var summary = e.Response.ResponseSummary;
            if ( summary.StatusCode == ResponseStatusCode.Success)
            {
                var results = e.Response.Results;

            }

        }

Further information :

1)  Using your silverlight demo app  and typing the same address works fine.

2) Creating a bing account and replacing the original demo VEKEy does not help either.

(VEKey = "AhLlRzBWylY8gMY5wLhyuckRQ0PQVbVKnTwdTiid5dNIeyP59nYQ6Tb0y_485DQi") 

  What's exactly the VEKEY? Creating an app in BING gives a completely different (size) token/id.

3) Exceptions in the GeoCode process are not correctly catched.

I am expecting here either an OnError event  , or that the Completed event gets called with Status= Failed.

4) Attached is a unit test that shows the problem

Ok, found my problem.

the answer is simple: i was using the Address whereas I should have used the Query property.

Found the answer thanks to this post:
