Re: [Boost-users] easy serialization question

Thanks for all your replies. This seems to work: ar & (CString::PCXSTR)m_strMyCString; that PCXSTR makes it const, I suppose. Is it possible though to serialize a char * pointer? Because I'm stuffing this into an std::string before serialzing, in reality, like: ar & std::string( (CString::PCXSTR)m_strMyCString); not so bad writing it, but reading it back in requires 3 lines: std::string strTemp; ar & strTemp; m_strMyCString = strTemp.c_str(); not sure if it's possible to just do it from a const char * pointer.

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.

Try casting it to an LPCTSTR. That should actually be far enough for the Serializer to work, as that is const pointer to a TChar array, and TChar is simply a wchar_t or char depending on if you have Unicode turned on. I wouldn't put any bets on the serialized data loading into another app that was compiled with the opposite Unicode setting.

ar & (LPCTSTR)(m_3rdPartyClass.m_SomeCString);
