    <p>I'm trying to do a very basic http POST to a web service from my Windows Phone 7 app. I know the web service works fine because I'm using it for three other mobile platforms.</p> <p>I've modified the C# example from <a href="http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.begingetrequeststream.aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.begingetrequeststream.aspx</a></p> <pre><code> string boundary = DateTime.Now.Ticks.ToString(); private void POST_TEST(object sender, RoutedEventArgs e) { HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Constants.JSON_URL_PREFIX + Settings.Settings.DeviceID + "/inquiry/new/"); request.ContentType = "multipart/form-data; boundary=" + boundary; request.Method = "POST"; request.BeginGetRequestStream(new AsyncCallback(GetRequestStreamCallback), request); } public void GetRequestStreamCallback(IAsyncResult asynchronousResult) { HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState; Stream postStream = request.EndGetRequestStream(asynchronousResult); StringBuilder postData = new StringBuilder(); postData.Append("--" + boundary + "\r\n"); postData.Append("Content-Disposition: form-data; name=\"body\"\r\n\r\n"); postData.Append("test 123"); postData.Append("\r\n--" + boundary + "\r\n"); byte[] byteArray = Encoding.UTF8.GetBytes(postData.ToString()); postStream.Write(byteArray, 0, postData.Length); postStream.Close(); request.BeginGetResponse(new AsyncCallback(GetResponseCallback), request); } private static void GetResponseCallback(IAsyncResult asynchronousResult) { HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState; // End the operation HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(asynchronousResult); Stream streamResponse = response.GetResponseStream(); StreamReader streamRead = new StreamReader(streamResponse); string responseString = streamRead.ReadToEnd(); // Close the stream object streamResponse.Close(); streamRead.Close(); // Release the HttpWebResponse response.Close(); } </code></pre> <p>I'm receiving "{ result: 'ok' }" from the server when I run this in the emulator, but "error: NotFound" when I run it on my Samsung Focus. I'm assuming this has to do with the way a string is converted to a byte[] on the phone versus a desktop computer.</p> <p>Any ideas on a fix? Maybe this is a known error that I never ran across searching the web for an answer?</p>

    1. CODoes the request reach the server? can you connect to the server from IE on the device?

    2. COYes, the request reaches the server. I know this because I'm getting a response from the server. It's not just timing out. Yes, I can connect to the web service in IE on the device.

    3. COif your device (via IE) isn't able to connect to the server then that should be your first point of investigation. If it's not possible to connect from device to server changes to your code aren't going to help.

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.
