## Remarks

If you're using Microsoft Visual Basic or Visual Basic for Applications (VBA), the syntax in this topic describes a common, efficient way to handle events.

If you want to create your own  **Event** objects, use the **Add** or **AddAdvise** method. To create an **Event** object that runs an add-on, use the **Add** method as it applies to the **EventList** collection. To create an **Event** object that receives notification, use the **AddAdvise** method. To find an event code for the event you want to create, see[Event codes](http://msdn.microsoft.com/library/de8f5c7a-421d-ebcf-22b6-4310a202ef64%28Office.15%29.aspx).
