    <p>First of all, I am a WEB NOOB. Which probably explains this question. Anyway, when I use the <a href="http://reports.gogetagrip.com/gateway/xml-submit-orders-test" rel="nofollow noreferrer">web page test app</a> to post xml to a url, everything works fine. Here is the pertinant code from the web page (i think):</p> <pre><code>&lt;form action="/gateway/xml" method="post" id="xml-test-form"&gt; &lt;textarea name="data"&gt; {some xml is in here} &lt;/textarea&gt; &lt;input type="submit" value="Submit Test" /&gt; &lt;/form&gt; </code></pre> <p>When I try to submit the exact same XML using C# (WebRequest or HttpWebRequest) with content type of ("text/xml" or "application/x-www-form-urlencoded") with a buffer encoded (ASCII or UTF8) I get an error that implies the XML cant be read at all on the other end. Here is the error:</p> <pre><code>&lt;?xml version="1.0"?&gt; &lt;SubmitOrdersResponse&gt; &lt;status code="0"&gt;FAILURE&lt;/status&gt; &lt;errors&gt; &lt;error code="1001"&gt;Invalid XML Version&lt;/error&gt; &lt;/errors&gt; &lt;/SubmitOrdersResponse&gt; &lt;br /&gt;&lt;b&gt;Warning&lt;/b&gt;: DOMDocument::loadXML() [&lt;a href='domdocument.loadxml'&gt;domdocument.loadxml&lt;/a&gt;]: Empty string supplied as input in &lt;b&gt;/var/www/vhosts/reports.gogetagrip.com/httpdocs/application/models/Gateway.php&lt;/b&gt; on line &lt;b&gt;90&lt;/b&gt;&lt;br /&gt; </code></pre> <p>I can reproduce this error using the web tester by removing a XML element named . I think this is the first element that is checked for, and hence the "INVALID XML VERSION" error. I think what is happening is my submittal is comming accross slighlty in the wrong format and that element can't be read. I think specifically I have to simulate a posting data where my data is comming from the "data" form field (see above). I don't know how to set that using the WebRequest class, so I can't test it. Here is my code:</p> <pre><code>static private void Post(string sURL, string sXml) { try { //Our postvars byte[] buffer = Encoding.UTF8.GetBytes(sXml); // Tried ASCII...same result HttpWebRequest WebReq = (HttpWebRequest)WebRequest.Create(sURL); // Tried WebRequest ... same result WebReq.Method = "POST"; WebReq.ContentType = "application/x-www-form-urlencoded"; // tried "text/xml"... same result WebReq.ContentLength = buffer.Length; Stream ReqStream = WebReq.GetRequestStream(); ReqStream.Write(buffer, 0, buffer.Length); ReqStream.Close(); WebResponse WebRes = WebReq.GetResponse(); //Console.WriteLine(WebResp.StatusCode); //Console.WriteLine(WebResp.Server); Stream ResStream = WebRes.GetResponseStream(); StreamReader ResReader = new StreamReader(ResStream); string sResponse = ResReader.ReadToEnd(); } catch (Exception ex) { } finally { } } </code></pre> <p>Any Ideas?????</p>

    1. COHey, my buddy suggested just adding "data=" to the front of my xml. VOILA! Is there a better way or is this what I should do?

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.
