How to Serialize a CListBox and members

I have a CFormview application that displays 4 list boxes on screen at the same time.  Each list box can have up to 12 CString data members.  How then do I serialize each of these members located inside the list box.  I have tried using the << and >> operators to serialize it as a whole but with no success.  I have a member variable declared for each list box which is known to both the doc and view.

Please help a newbie.

Thanks

You must write the serialization code yourself, based on the serializability of CStrings.

Iterate through all the string members of each listbox (a loop is fine), retrieve the CString value associated with each item and insert it into the archive with the << operator.
Loading is exactly the contrary: first read the string from the archive, then insert it into the listboxes.
