    <p>I am calling Classic ASP Webservices from a .NET application. I have two instances of slow processing of the webservice and fast processing. </p> <p>The slow way (several seconds at the most) is where I actually read the data returned as such:</p> <pre><code>Dim oRequestAOCP As WebRequest Dim oResponseAOCP As HttpWebResponse = Nothing Dim dataStreamAOCP As Stream = Nothing Dim readerAOCP As StreamReader = Nothing Dim responseFromServerAOCP As String Dim sAOCP = Session("SecureURL") &amp; "/services/rtOrderEntryAOCP.asp" sAOCP = sAOCP &amp; "?coskey=" &amp; Server.UrlEncode(Session("GUID")) sAOCP = sAOCP &amp; "&amp;OrderID=" &amp; Server.UrlEncode(Session("OrderID")) oRequestAOCP = WebRequest.Create(sAOCP) oRequestAOCP = CType(oRequestAOCP, HttpWebRequest) oRequestAOCP.Method = "GET" oResponseAOCP = CType(oRequestAOCP.GetResponse(), HttpWebResponse) dataStreamAOCP = oResponseAOCP.GetResponseStream() readerAOCP = New StreamReader(dataStreamAOCP) responseFromServerAOCP = readerAOCP.ReadToEnd() Dim xmlAOCP As New XmlDocument() xmlAOCP.LoadXml(responseFromServerAOCP) Dim nodeAOCP As XmlNodeList = xmlAOCP.GetElementsByTagName("SUCCESS") Dim valueAOCP = CBool(nodeAOCP(0).InnerText) </code></pre> <p>Then, the following is quite fast (sub-second), where I only expect the HTTP status to be returned and nothing else - not a good MO, due to needing data back from webservices in most cases.</p> <pre><code>Dim oRequest As WebRequest Dim oResponse As HttpWebResponse = Nothing Dim oEmail As New Email() 'now, call the webservice to get the AESBlock Dim strUrl = Session("SecureURL") &amp; "/services/rtOrderEntryStatusUpdate.asp" strUrl = strUrl &amp; "?GUID=" &amp; Server.UrlEncode(Session("MISCGUID")) strUrl = strUrl &amp; "&amp;Status=" &amp; Server.UrlEncode(sStatus) strUrl = strUrl &amp; "&amp;Error=" &amp; Server.UrlEncode(sError) 'make the call to the webservice to prime the order oRequest = WebRequest.Create(strUrl) oRequest = CType(oRequest, HttpWebRequest) oRequest.Method = "GET" oResponse = CType(oRequest.GetResponse(), HttpWebResponse) </code></pre> <p>What can I do to speed things up when I need data returned?</p>

    1. COFirst of all, you need to get the response, stream, and streamreader into Using blocks so they get disposed. That can affect performance.

    2. COI dispose of them in the Finally block of the Try Catch, which I did not include in the code snippet.

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).
