    <p>For the last few months I've been finding the locations of cell towers as we use their cellid and areaid, based on the following code:</p> <pre><code> public class GoogleService { public GoogleCell GetCellInfo(string lac, string mnc, string mcc, string cellID) { try { HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create("https://www.google.com/loc/json"); myReq.Method = "POST"; myReq.ContentType = "application/jsonrequest"; string postData = "{\"cell_towers\": [{\"location_area_code\": \"" + lac + "\", \"mobile_network_code\": \"" + mnc + "\", \"cell_id\": \"" + cellID + "\", \"mobile_country_code\": \"" + mcc + "\"}], \"version\": \"1.1.0\", \"request_address\": \"true\"}"; myReq.ContentLength = postData.Length; StreamWriter stOut = new StreamWriter(myReq.GetRequestStream(), System.Text.Encoding.ASCII); stOut.Write(postData); stOut.Close(); HttpWebResponse webresponse; webresponse = (HttpWebResponse)myReq.GetResponse(); Encoding enc = System.Text.Encoding.UTF8; StreamReader loResponseStream = new StreamReader(webresponse.GetResponseStream(), enc); string Response = loResponseStream.ReadToEnd(); loResponseStream.Close(); webresponse.Close(); GoogleCell Mycell = JsonConvert.DeserializeObject&lt;GoogleCell&gt;(Response); return Mycell; } catch (Exception ex) { string strErr = ex.Message; if (ex.InnerException != null) { strErr += ": " + ex.InnerException.Message; } MessageBox.Show(strErr); return new GoogleCell(); } } } public class GoogleCell { public GoogleCell() { } public GoogleCell(string mnc, string mcc, string lac) { this.Mnc = mnc; this.Mcc = mcc; this.Lac = lac; } public string Mnc { get; set; } public string Mcc { get; set; } public string Lac { get; set; } public string CellID { get; set; } public Location location { get; set; } public class Location { public Location() { } public Location(string latitude, string longitude) { this.latitude = latitude; this.longitude = longitude; } public string latitude { get; set; } public string longitude { get; set; } public Address address { get; set; } public class Address { public Address() { } public string country { get; set; } public string country_code { get; set; } public string city { get; set; } public string region { get; set; } public string street { get; set; } public string street_number { get; set; } public string postal_code { get; set; } } } </code></pre> <p>The code worked flawlessly until sometime between one and two weeks ago, when it started returning error 400: Bad Request when it does the GetRequestStream().</p> <p>My code hasn't changed. I can't find any record of the API's parameters changing. What else could be going on? This uses Google Gears, which has been deprecated for a while now, but I can't find any doco on a replacement <strong>that finds cell towers.</strong></p> <p>any ideas?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
