Introduction

This post is about a multi language switcher dynamically written in WPF VB.NET using XMLDataProvider:

Using the Code

Private Sub limbiSwitch_SelectionChanged(sender As Object, e As SelectionChangedEventArgs)
       Dim combo_switcher As ComboBox = DirectCast(sender, ComboBox)
       Dim e1 As XmlElement = TryCast(langSwitcher.SelectedItem, XmlElement)
       If e1 IsNot Nothing Then
           Dim result1 As XmlAttribute = TryCast(e1.Attributes("file"), XmlAttribute)
           If result1 IsNot Nothing Then
               Dim lang_filename As String = result1.Value
               If lang_filename IsNot selected_language Then
                   Dim provider = DirectCast(Me.Resources("Lang"), XmlDataProvider)
                   Dim lang_url As String = AppDomain.CurrentDomain.BaseDirectory() + _
                   "languages\" + lang_filename
                   If Not System.IO.File.Exists(lang_url) Then
                       Return
                   End If
                   provider.Source = New Uri(lang_url)
                   provider.Refresh()
               End If
           End If
       End If
   End Sub

Language names and translated words are loaded dynamically from XML files.
