VBA Powerpoint 2013: change presentation language including SmartArt objects

Question

I can not find a way to change by VBA script the language in SmartArt objects in Powerpoint 2013. I've seen PowerPoint 2007 - Set language on tables, charts etc that contains text but it does not work for SmartArt objects. Any idea how I could do this? Many thanks.

Answer 1

This is the code I finally use to change the language including SmartArts:

Sub SetLangUS()
  Call changeLanguage(ActivePresentation, "US")
End Sub

Sub SetLangDE()
  Call changeLanguage(ActivePresentation, "DE")
End Sub



Private Function changeLanguage(oPres As Presentation, langStr As String)

    'lang = "Norwegian"
    'Determine language selected
    If langStr = "US" Then
        lang = msoLanguageIDEnglishUS
    ElseIf langStr = "UK" Then
        lang = msoLanguageIDEnglishUK

    For Each oSlide In oPres.Slides
        For Each oShape In oSlide.Shapes
            'Check first if it is a table
            If oShape.HasTable Then
                For r = 1 To oShape.Table.Rows.Count
                    For c = 1 To oShape.Table.Columns.Count
                        oShape.Table.Cell(r, c).Shape.TextFrame.TextRange.LanguageID = lang
