Notice that in line 1 of the code we set up a variable containing the XML
required for querying the Web service. To do an MSSQLFT search instead of a
STRING search, just change type=\"STRING\" to type=\"MSSQLFT\". But if you do that,
the text box needs to contain a query rather than just a string when the button is
clicked.
In line 7 of the code, you submit the query XML using QueryEx to return a
dataset. Using Query rather than QueryEx will return an xmlNode with basically the
same data. The dataset is just a little easier to work with, even though the names of
the fields are long. Speaking of the field names, notice that %3a is the escape
sequence for a colon. Mentally substituting those three characters when looking at
the preceding code will make the field names easier to understand.
Finally, place the following code in the treeView1_AfterSelect function:
private void treeView1_AfterSelect(object sender,
System.Windows.Forms.TreeViewEventArgs e)
{
//1. Setup a variable representing a latent process with
// IE (iexplore.exe) as the application and the URL
// in the clicked node's tag as the document to open
System.Diagnostics.ProcessStartInfo iexploreStartInfo = new
System.Diagnostics.ProcessStartInfo(
"iexplore.exe", e.Node.Tag.ToString());
}
//2. Starting the process opens IE to the URL
System.Diagnostics.Process iexplore =
System.Diagnostics.Process.Start(iexploreStartInfo);
Replace the text in the text box with the keywords you want to search for. In
our example, you searched for the word “microsoft”. Click the button. If searching
a brand new portal site, there should be a number of resources found (typically
five), as shown in Figure 36-3.
Click any resource listed in the tree view and your browser will open directly
to that resource’s URL.
