[msvc] About std::list

[Juan Carlos]

Hi,   I�m beginning with stl list containers.  So far I�ve always been using the MFC collections but now I need to port an app to Linux so I thought stl collections are a better alternative..   Anyway, I believe this should be a trivial question, in particular, about the correct use of the stl::list collection and iterators. Lets say I have the following class:   CMyClass {             (�)             std::list <CMyObject> m_MyList;             (�) }   and that I want to add methods to this class for adding, removing and showing CMyObject items. In my previous implementations with MFC, I added a CMyObject pointer data member that pointed to the current item in the list: CMyObject *  m_pCurrentObject; This pointer is initialized to NULL in the constructor and then is assigned to every item added to the list. My question is: should I use now an iterator (as a data member in CMyClass) to keep track of the current item in the list? I know that iterators are invalidated with some operations such as erase(). Is there a better approach?   Thanks for your advices. Carlos
