Get String From Webpage

[Tddupre]

ok here is my code

Dim objRegEx As System.Text.RegularExpressions.Regex
        Dim objMatch As System.Text.RegularExpressions.Match
        Dim arrLinks As New System.Collections.ArrayList()
        ' Create regular expression
        objRegEx = New System.Text.RegularExpressions.Regex( _
            "(?<=<a rel='lightbox' href=).*(?=>Image Only</a></td>)", _
            System.Text.RegularExpressions.RegexOptions.IgnoreCase Or _
            System.Text.RegularExpressions.RegexOptions.Compiled)
        ' Match expression to HTML
        objMatch = objRegEx.Match(HTML)
        ' Loop through matches and add <1> to ArrayList
        While objMatch.Success
            Dim strMatch As String
            strMatch = objMatch.Groups(1).ToString
            ListBox1.Items.Add(strMatch)
            objMatch = objMatch.NextMatch()
        End While

but it is just adding blank lines to the listbox and not the strings it found
