So there should be a way to get last Domain/Name from Path only. Any ideas how to do it with this library?

    Using picker
        If picker.ShowDialog() = DialogResult.OK Then
            For Each sel In picker.SelectedObjects
                Dim aString As String = Replace(sel.Path, "WinNT://WORKGROUP/", String.Empty)
                Dim cString As String = Replace(aString , "/", "\")
                ComboBox1.Items.Add(cString)
                'MsgBox(sel.Path)
            Next
        End If
    End Using
