Application.LanguageSettings (Access)
You can use the LanguageSettings property to return a read-only reference to the current LanguageSettings object and its related properties.
After you establish a reference to the LanguageSettings object, you can access all the properties and methods of the object. You can set a reference to the LanguageSettings object by choosing References on the Tools menu while in module Design view. You can then set a reference to the Microsoft Office Object Library in the References dialog box by selecting the appropriate check box. Microsoft Access can set this reference for you if you use a Microsoft Office Object Library constant to set a LanguageSettings object's property or as an argument to a LanguageSettings object's method.
