    <p>I was asked to send a request to a server to register online a transaction for a point gathering system. I don know much about this request-respond procedure.</p> <p>They told me that the request should be like this:</p> <pre><code>request( p1 - loginInfo:UN|PASS|MP1 p2 - XMLTransactionInfo (below) p3 - returnPointBalance:1 ) &lt;transaction&gt; &lt;partnernum&gt;000001&lt;/partnernum&gt; &lt;trxndate&gt;2012-10-&gt;12T07:18:27&lt;/trxndate&gt; &lt;cardnum&gt;1234567891234567&lt;/cardnum&gt; &lt;trxnamount&gt;5.4&lt;/trxnamount&gt; &lt;trxnpoints&gt;729&lt;/trxnpoints&gt; &lt;posnum&gt;000-001&lt;/posnum&gt; &lt;contactidnum&gt;&lt;/contactidnum&gt; &lt;contactphone&gt;357&lt;/contactphone&gt; &lt;trxnseqnum&gt;12345612345612&lt;/trxnseqnum&gt; &lt;/transaction&gt; </code></pre> <p>And the response should be like this:</p> <pre><code>response( &lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;transactionresponse xmlns="C:\path\Sth.ear\Sth.war/xmlschema/TransactionResponse.rng"&gt; &lt;sequencenum&gt;123123121312&lt;/sequencenum&gt; &lt;errorcode&gt;0&lt;/errorcode&gt; &lt;errormessage&gt;&lt;/errormessage&gt; &lt;trxnnum&gt;6399575&lt;/trxnnum&gt; &lt;balancebefore&gt;1942&lt;/balancebefore&gt; &lt;balanceafter&gt;1213&lt;/balanceafter&gt; &lt;mpcontrib&gt;729&lt;/mpcontrib&gt; &lt;partnercontrib&gt;0&lt;/partnercontrib&gt; &lt;/transactionresponse&gt; ) </code></pre> <p>They also told me: "You can get the WSDL with this URL: url1..." and "The WS endpoint is: url2..."</p> <p>So far i've managed to do the following:</p> <pre><code>Dim request As WebRequest = Nothing 'Create a request for the URL. request =WebRequest.Create("URL1") 'set the credentials. Dim credentials As NetworkCredential loginUser = "username" loginPass = "pass" credentials = New NetworkCredential(loginUser, loginPass, "MP1") request.Credentials = credentials 'create the transaction xml request.ContentType = "text/xml" Dim transaction As XmlElement transaction = xml2.CreateElement("transaction") xml2.AppendChild(transaction) Dim partnernum As XmlElement partnernum = xml2.CreateElement("partnernum") partnernum.InnerText = "00001" transaction.AppendChild(partnernum) 'and so on until i create the exact same xml as above... </code></pre> <p>Then I print the XML file to the console for a visual check and then ask for response</p> <pre><code> 'print to console xml2.Save(Console.Out) Dim response As WebResponse = request.GetResponse() Console.WriteLine(response.ToString()) 'write the response to a textbox responseText.Text = response.Headers.ToString() </code></pre> <p>The result of the response in the textbox is</p> <pre><code>Content-Language: el-GR Transfer-Encoding: chunked Content-Type: text/xml Date: Thu, 13 Dec 2012 18:52:33 GMT Server: WebSphere Application Server/6.0 </code></pre> <p>Firstly which one of the 2 urls that they gave me I should I use?</p> <p>Secondly how can I create the request that they told me in order to get the response I am suppose to get?</p> <p>Is there any step by step guide for that?</p> <p>I am using VB.net, WinForms. Thank you for your time.</p>

COKBoek's answer on this thread: http://stackoverflow.com/questions/3757731/how-to-read-xml-from-remote-url-in-vb-net might steer you in the right direction - couldn't really tell if it applies (might answer your 1st and 2nd questions). Additionally, I found this from a bit more digging: http://robz.homedns.org:8080/blog/archive/2005/02/25/387.aspx

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
