public event EventHandler<AnnAfterObjectChangedEventArgs> AfterObjectChanged

'Declaration
 
Public Event AfterObjectChanged As EventHandler(Of AnnAfterObjectChangedEventArgs)

'Usage
 
Dim instance As AnnAutomation
Dim handler As EventHandler(Of AnnAfterObjectChangedEventArgs)
 
AddHandler instance.AfterObjectChanged, handler

public:
event EventHandler<AnnAfterObjectChangedEventArgs^>^ AfterObjectChanged

The event handler receives an argument of type AnnAfterObjectChangedEventArgs containing data related to this event. The following AnnAfterObjectChangedEventArgs properties provide information specific to this event.

Property	Description
ChangeType	Gets the type of change.
Designer	Gets the designer responsible for the change.
Objects	Gets the objects that have been changed.

This event will be fired after an AnnObject has been modified by this AnnAutomation

NOTE: The object is not inserted into the Automation's container until this event has returned. This is to allow the user to cancel the Insertion operation.

This example will subscribe to the AfterObjectChanged event of all automations and print out a message every time an object changes.
