C / C++ / MFC

1. What you store are not CObjects, but pointers to CObject created with new (CObList assumes responsibility for deleteing them later). In particular, you cannot store simple types like ints or structs not deriving from CObject.
   
2. When you retrieve an object stored in a CObList (well, a pointer to it), you have to figure out its actual type and downcast (most usually what you store are not CObjects but some other class derive from this type.)

1. Create a list of 100 CStuff objects.
   
2. Define CStuff to behave as a CObist of fixed size (100).
   
3. Other.

class CStuff: public CObject
{
... // as before
};

stuffList.AddTail(new CStuff(/*args here if ctor needs them */));

std::list<CStuff> stuffList;
...
stuffList.push_back(CStuff()); // no new here, we store objects rather than pointers to them
