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).
