Three (3) List classes to prevent memory leaks

Posted by Simon Hughes on July 13th, 1999

Here are two template classes and one normal class designed to prevent memory leaks.

CMyList (template)
This class is a wrapper for the CList MFC template class. It adds extra functionality and allows its member items to serialise themselves (important for schema versioning).

CMyTypedPtrList (template) my personal favourate
This class is a wrapper for the CTypedPtrList MFC template class. The items pointed to will be properly deleted thus causing no memory leaks.

CMyObList (standard class)
This class is a wrapper for the CObList MFC class. The items pointed to will be properly deleted thus causing no memory leaks.

    void Serialize(CArchive &ar)

    {

    	if(ar.IsLoading())

    		RemoveAll();

    	CTypedPtrList<CObList, TYPE*>::Serialize(ar);

    }


    Add the following to the CMyObList class.

    void Serialize(CArchive &ar)

    {

    	if(ar.IsLoading())

    		RemoveAll();

    	CObList::Serialize(ar);

    }
