Exempel

I följande exempel skapas en ny Form och en händelsehanterare kopplas InputLanguageChanged till händelsen. Den här händelsen ändrar IMEmode när indataspråket ändras till japanska.

Kommentarer

När du skapar ett InputLanguageChangedEventHandler ombud identifierar du den metod som ska hantera händelsen. Om du vill associera händelsen med händelsehanteraren lägger du till en instans av ombudet till händelsen. Händelsehanteraren anropas när händelsen inträffar, såvida du inte tar bort ombudet.

Mer information om ombud för händelsehanterare finns i Hantera och höja händelser.
