This sample not only displays formatted content in the <b class="bterm">Research</b> task pane from the<b class="bterm"> Response.Content</b> and the <b class="bterm">Response.Form</b> namespaces, but it also enhances the query results with custom actions implemented in a smart tag DLL. In this topic, we take a look at the IBuySpy sample and some of the techniques it uses to achieve powerful results in the <b class="bterm">Research</b> task pane.</p><p><b>Important</b> Since the IBuySpy sample includes complete source code, this topic includes only limited excerpts from the code. The excerpts that are shown may omit variable declarations, error handling, and other important sections of the code. We suggest that you set up the IBuySpy sample and open it in Microsoft Visual Studio® .NET so that you can follow along during this walkthrough. Note that the <code>Utils</code> class referenced in the code samples in this topic is a helper class of support functions in the IBuySpy sample.</p><p><a href="#" class="DropDown" onclick="Outline2()" onkeypress="Outline2()"><img border="0" src="blueup.gif" alt="Show"><b class="bterm">Registration</b> method</a></p><div id="ExpCol" class="collapsed" border="0"><p>When a client computer calls the <b class="bterm">Registration</b> Web method of the IBuySpy sample, the <b class="bterm">Registration</b> method takes the following steps to assemble the registration response packet:<ol><li>The <b class="bterm">Registration</b> method loads the contents of a saved XML template file (RegistrationResponse.xml) into a new <b class="bterm">XMLDocument</b>.<pre><code>Dim xdResponse As New XmlDocument

(The sample code does not reference the <b class="bterm">Microsoft.Search.Query.Office.Keywords</b> namespace since it does not use the contents of the <b class="bterm">Keywords</b> section of the query packet.)<pre><code>Dim requestXml As New XmlDocument()
...
requestXml.LoadXml(queryXml)
Dim nsmRequest As New XmlNamespaceManager(requestXml.NameTable)
With nsmRequest
.AddNamespace("ns", "urn:Microsoft.Search.Query")
.AddNamespace("sp", _
"urn:Microsoft.Search.Office.ServiceParameters")
.AddNamespace("oc", "urn:Microsoft.Search.Query.Office.Context")
End With
</code></pre></li><li>Next, the <b class="bterm">Query</b> method extracts the text of the user's query and the name of the Microsoft Office host application.<pre><code>queryTerm = requestXml.SelectSingleNode("//ns:QueryText", _
nsmRequest).InnerText
applicationName = requestXml.SelectSingleNode("//oc:Name", _
nsmRequest).InnerText
</code></pre></li><li>Then the <b class="bterm">Query</b> method loads the contents of a saved XML template file (ResponsePacketWrapper.xml) into a new <b class="bterm">XmlDocument</b>.<pre><code>responseWrapper.Load(Utils.GetCurrentPath & _
"\xml\ResponsePacketWrapper.xml")
Dim nsmResponseWrapper As New _
XmlNamespaceManager(responseWrapper.NameTable)
nsmResponseWrapper.AddNamespace( _
"ns", "urn:Microsoft.Search.Response")
</code></pre>This template file contains a query response consisting largely of empty tags. The rest of the code in the <b class="bterm">Query</b> method and in its supporting methods fills in the <b class="bterm">Results</b> element of the template. The empty template file looks like this:<pre><code><?xml version="1.0" encoding="utf-8"?>
<ResponsePacket revision="1" xmlns="urn:Microsoft.Search.Response">
<Response domain="{1698075D-E2F5-4254-87B2-7FC9E9AB0780}">

<Range>
<Results>
</Results>
</Range>
<Status>SUCCESS</Status>
</Response>
</ResponsePacket>
</code></pre></li><li>Finally, the <b class="bterm">Query</b> method uses an <code>If/ElseIf</code> block to determine what type of query the user has submitted, and to call the appropriate one of six private methods (whose names begin with the <code>Response_</code> prefix) that process specific query types such as Product Details and Products by Category. After the helper method returns its results, the <b class="bterm">Query</b> method adds these results to the query response template and returns the string contents of the completed <b class="bterm">XmlDocument</b> to the client computer.<pre><code>responseWrapper.SelectSingleNode("//ns:Results", _
nsmResponseWrapper).InnerXml = responseBody.ToString
Return responseWrapper.InnerXml.ToString
</code></pre></li></ol></p></div><p>In the following sections, we take a look at six different query scenarios in the IBuySpy sample. For each query scenario, we examine:<ol><li>The steps to follow in Microsoft Office Word 2003 to launch the query.</li><li>The visual results of the query in the <b class="bterm">Research</b> task pane.</li><li>The important portions of the XML query request packet sent from the <b class="bterm">Research</b> task pane to the research service.</li><li>The important portions of the research service code that processes the query.</li><li>The important portions of the XML query response packet returned by the research service to the <b class="bterm">Research</b> task pane.</li></ol></p><p><a href="#" class="DropDown" onclick="Outline2()" onkeypress="Outline2()"><img border="0" src="blueup.gif" alt="Show"><b class="bterm">Query</b> method: Keyword search (no results found)</a></p><div id="ExpCol" class="collapsed" border="0"><p>This section demonstrates a keyword search query that does not return results and calls the <code>Response_NoResults</code> private method in the IBuySpy sample.</p><ol><li><b class="bterm">Steps</b>.
