XML displays in console but not in text boxes

[John Meyer]

The console code is working just fine, but it isn't putting in the text
boxes.

P.S I'm using a while loop, but I'm only expecting one answer but I
haven't found a good way to process one record.

Private Sub btnFindByISBN_C lick(ByVal sender As System.Object, ByVal e
As System.EventArg s) Handles btnFindByISBN.C lick
Dim strSearchString As String

strSearchString = "http://isbndb.com/api/books.xml?acces s_key="
& "CYGCL3GT" & "&index1=isbn&v alue1=" & Me.txtISBN.Text



Dim reader As XmlTextReader = New XmlTextReader(s trSearchString)
Do While (reader.Read())
Console.WriteLi ne(reader.Name)
Console.WriteLi ne(reader.Value )

Select Case reader.Name
Case "Title"
Me.txtTitle.Tex t = reader.Value
Case "AuthorsTex t"
Me.txtAuthors.T ext = reader.Value
End Select
Loop




End Sub

Visual Basic.NET 2008

With VB.NET 2008 you could use LINQ to XML instead of Xml(Text)Reader ,
see MSDN online or your local copy:

http://msdn.microsoft.com/en-us/library/bb387098.aspx

As for your code above, with the XmlReader API you can use code like this:
Using reader As XmlReader = XmlReader.Creat e(strSearchStri ng)
While reader.Read()
If reader.NodeType = XmlNodeType.Ele ment And reader.Name =
"Title" Then
Me.txtTitle.Tex t = reader.ReadStri ng()
Else if reader.NodeType = XmlNodeType.Ele ment And reader.Name =
"AuthorsTex t" Then
Me.txtAuthors.T ext = reader.ReadStri ng()
End If
End While
End Using

If that does not help then show us how a sample of the XML looks.

Yeah, I originally posted this in m.p.vb.general. discussion but somebody
said that I was talking Visual Basic.NET, not real Visual Basic. Go fig.
