LanguageID in a Word Document (VB)

ManuelR 1

I have a Microsoft.Office.Interop.Word.Document object, this object has a function named Range, and with that Range I can get the LanguageID of the selected text in the Range.
I have this:

  Dim objDoc As Microsoft.Office.Interop.Word.Document = Document

 Select Case objDoc.Range.LanguageID
                Case WdLanguageID.wdSpanish,
 WdLanguageID.wdSpanishModernSort
                    defaultLang = "es"
                Case WdLanguageID.wdCatalan
                    defaultLang = "ca"
                Case WdLanguageID.wdBasque
                    defaultLang = "eu"
                Case WdLanguageID.wdPortuguese
                    defaultLang = "pt"
                Case WdLanguageID.wdEnglishUK, WdLanguageID.wdEnglishUS
                    defaultLang = "en"
                Case Else
                    defaultLang = "es"
            End Select

How does the LanguageID work? where does it come from? Can I change it? Can I access to it outside the code? (using ms word)

Thank you in advance

Language ID is not a document property but is actually set at the character level.
It can be in the form of direct formatting or contained in styles. There can be multiple languages in a single document.

To add to what Charles has said, you can set the language ID for all the text in the main body of the document, but the language formatting will be more flexible if you control it by other means. For example, in a multi-language document, define specific paragraph or character styles for different languages.

That said, the language ID:s and their corresponding numeric values can be found in the Visual Basic Editor in Word. Press F2 to show the object browser. Find the wdLanguageID constants.
