看起来像LanguageSetting 对象

It looks that LanguageSetting  object http://msdn.microsoft.com/en-us/library/aa219863(office.11).aspx in VBA is read-only in terms of localization properties. I can read them, but cannot change:

在我的电脑上：

？Application.LanguageSettings.LanguagePreferredForEditing（msoLanguageIDEnglishCanadian）= True

?Application.LanguageSettings.LanguagePreferredForEditing(msoLanguageIDEnglishCanadian)=True

？Application.LanguageSettings.LanguageId（msoLanguageIDUI）= 1033

?Application.LanguageSettings.LanguageId(msoLanguageIDUI)=1033

您可以尝试使用以下代码：Application.Presentations（1）.LayoutDirection = ppDirectionLeftToRight。

You can try to use code like: Application.Presentations(1).LayoutDirection = ppDirectionLeftToRight.
