Determining the IDO for an Event Handler

To determine the IDO you need for a handler:

Open the form for which you are creating the handler.

For example, to create a handler that notifies you when a new customer is added to the database, open the Customers form.
Go into design mode for the form.
On the Form Properties sheet, click the Collections tab.

The IDO is displayed in the Collections tree. The actual name of the IDO is shown after the period.
