Vector Notification Messages
When calling vector class library functions, notification messages are sent through the LVectorBase::StartChanging and LVectorBase::EndChanging member functions. These functions are called before and after executing the function that changes the vector. By overriding the virtual functions, you can do other processing, or even halt the operation. For a complete list of messages, please refer to Bitmap and Vector Change Notifications and Notification Categories
The following methods are used in conjunction with vector notification messages:
LVectorBase::EnableChangeNotification
LVectorBase::IsChangeNotificationEnabled
