G'day ppaulerrol,

I had the same problem & have come up with a workaround, see below.

Instead of using the inbuilt GMapControl.SetPositionByKeywords() function, I wrote my own local version of based on almost the same code. Seems to work now, but is a bit slower than it was before. I'm not 100% sure why this works but it seems to !

Hope this helps ? Cheers :) Simon

public bool SetPositionByKeywords(string searchWord)
        {
            GeocodingProvider gp = GMap.NET.MapProviders.GMapProviders.OpenStreetMap as GeocodingProvider;

            if (gp != null)
            {
                GeoCoderStatusCode status = GeoCoderStatusCode.Unknow;

                Cursor.Current = Cursors.WaitCursor;
                var pt = gp.GetPoint(searchWord, out status);
                Cursor.Current = Cursors.Default;

                if (status == GeoCoderStatusCode.G_GEO_SUCCESS && pt.HasValue)
                {
                    this.gMapControl1.Position = pt.Value;

                    return true;
                }
                else
                {
                    // error
                    MessageBox.Show("Could not find \"" + searchWord + "\"");
                    return false;
                }
            }
            else
            {
                MessageBox.Show("Could not find \"" + searchWord + "\"");
                return false;
            }
        }

thank you bro! i used your code but it is just like the same.. i can't locate the places id like to see in gmap.net. is it a bug or an update error?.

[cronky78]

Hmm that's strange, it works just fine for me. The trick is in forcing the GeocodingProvider
to be of type 'GMap.NET.MapProviders.GMapProviders.OpenStreetMap' instead of what you were using before (probably Google). Seems to me that Google have changed something their end recently. But by using OpenStreetMap specifically I am able to search again and it's working. Wonder if anyone else can try it too ?

Greetings, perform the test with the library method using Google Map Map Provider and OpenStreetMap and work without problems. It could indicate how you were using it and what provider, if you are using the sources or the nuget and if you are using an apikey. I leave an example as I am using it.

GeoCoderStatusCode status = MainMap.SetPositionByKeywords(textBoxGeo.Text);

            if (status != GeoCoderStatusCode.G_GEO_SUCCESS)
            {
                MessageBox.Show("Geocoder can't find: '" + textBoxGeo.Text + "', reason: " + status.ToString(), "GMap.NET", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
            }

i think somethings wrong with Google map provider because when i use OpenStreetMap it works..

[ppaulerrol]

try using any map provider and it will work. but not google map.

[judero01col]

Are you using a valid api key?

[ppaulerrol]

valid api key? i dont understand.

[Maesetsure]

I have the same problem. With Google don't work but with other providers works fine.

[prkrmx]

for some reason it stopped working also with BingHybridMap
GeoCoderStatusCode returns ExeptionInCode

[MartinStokelj]

Was there any update on this problem? I made work around with OpenStreetMap but now even this do not work anymore...

    public GeoCoderStatusCode SetPositionByKeywords(string keys)
    {
        GeoCoderStatusCode status = GeoCoderStatusCode.Unknow;
        GeocodingProvider gp = MapProvider as GeocodingProvider;
        if (gp == null)
        {
            gp = GMapProviders.OpenStreetMap as GeocodingProvider;
        }

        if (gp != null)
        {
            var pt = gp.GetPoint(keys, out status);
            if (status == GeoCoderStatusCode.G_GEO_SUCCESS && pt.HasValue)
            {
                Position = pt.Value;
            }
            else
            {
                gp = GMapProviders.OpenStreetMap as GeocodingProvider;
                pt = gp.GetPoint(keys, out status);
                if (status == GeoCoderStatusCode.G_GEO_SUCCESS && pt.HasValue)
                {
                    Position = pt.Value;
                }
            }
        }

        if (status != GeoCoderStatusCode.G_GEO_SUCCESS && !gp.GetType().ToString().Contains("Google"))
        {
            var pt = GMapProviders.GoogleMap.GetPoint(keys, out status);
            if (status == GeoCoderStatusCode.G_GEO_SUCCESS && pt.HasValue)
            {
                Position = pt.Value;
            }
        }

        return status;
    }

Never mind i had to update also code for class OpenStreetMapProviderBase, after that it started to work.

I proceed with the closing of the issues, review issues #51

Thanks a lot! I wrote the same function myself, but for some reason it did not work for me. But yours is working <3
