Raises the BeforeObjectChanged event.
Syntax
protected virtual void OnBeforeObjectChanged( 
   AnnBeforeObjectChangedEventArgs e
)
'Declaration
 
Protected Overridable Sub OnBeforeObjectChanged( _
   ByVal e As AnnBeforeObjectChangedEventArgs _
) 
'Usage
 
Dim instance As AnnAutomation
Dim e As AnnBeforeObjectChangedEventArgs
 
instance.OnBeforeObjectChanged(e)

            

            
protected:
virtual void OnBeforeObjectChanged( 
   AnnBeforeObjectChangedEventArgs^ e
) 

Parameters

e
An AnnBeforeObjectChangedEventArgs that contains the event data.
Remarks
Raising an event invokes the event handler through a delegate. The OnBeforeObjectChanged method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class. Notes to Inheritors: When overriding OnBeforeObjectChanged in a derived class, be sure to call the base class's OnBeforeObjectChanged method so that registered delegates receive the event.
Example
For an example, refer to BeforeObjectChanged.
