Comments
The LVectorBase::EnumObjects function calls your callback function as it gets the handle of each vector object.
To use this function, you must do the following:
1. Derive a class from LVectorBase.
2. Override the L_INT LVectorBase::EnumObjectsCallBack. Function in your class.
3. Before calling LVectorBase::EnumObjects, you must call the member function LBase::EnableCallBack(TRUE).
