Hmm ok I split up the save() and load() functions so I can just serialize the individual members of these 3rd party classes. That works ok. The save() method is defined like:
voidd save(Archive &ar, const unsigned int version) const { ar & m_3rdPartyClass.m_SomeInteger; ... }
One of the data types though is MFC's CString - which is just like std:string, just a wrapper around a character array. The only way to get the contents of a CString as a char array is a function called GetBuffer() which returns a non-const char pointer to the internal array. My compiler does not seem to like this, as I guess the save() function is defined as const? Is this right, and if so, is there any way I can get around this one?
ar & m_3rdPartyClass.m_SomeCString.GetBuffer(); // returns non const char* !!
I don't know how serialization for std::string is done, but it's supported by the library. Maybe you could create a temporary std::string from your MFC string and serialize that one instead? Though there may be a decrease in performance if you have a lot of strings to deal with. -- Regards, dave
