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.
