Description |

Boolean by reference; determines whether the change will be canceled. Values are:

None. Do not use a RETURN statement.
Property change notifications are not supported by all OLE servers. The PropertyRequestEdit and PropertyChanged events only occur when the server supports these notifications.
Property notifications are not sent when the object is being created or loaded. Otherwise, notifications are sent for all bindable properties, no matter how the property is being changed.
The PropertyRequestEdit event gives you a chance to access the property’s old value using the automation interface and save it. To cancel the change, set the cancelchange argument to true.
