Overriding void AFXAPI SerializeElements [modified]

[C++ Programming]

Hi all,

As you probably know, there is a problem with CString types in CList, CMap or CArray with regards to serialization. I have attempted to remedy this by overriding void AFXAPI SerializeElements. Before I post my code though, I'd like to ask if any other MFC container class can serialize CStrings correctly, for example CTypedPtrList? I'm not real particular on the container class for my current app and figuring out the peculiarities of serialize is exhausting.

The problem with the code below is that even after overriding SerializeElements, I get a mem copy error when doing a serialize load operation. A breakpoint in SerializeElements is never hit so for some reason it's not being used. I also have a serialize() function for the base class elements but it's not used either, presumably because all base elements are CSTRINGs? There are 2 classes, one for the base elements and another with the CList and functions. BTW, the functions that save and load the list are called from inside the Doc class serialize function.

Thanks in advance -
