Remarks

You can use the data from the InputLanguageChangedEventArgs to make decisions about whether to change Input Method Editors (IMEs) or swap right-to-left values. You can also change the CurrentCulture of a thread and the CurrentUICulture properties so that different resources get picked up.

An InputLanguageChangedEventArgs identifies the locale and the character set of the new input language.

The InputLanguageChanging event precedes the InputLanguageChanged event.
