Re: [Boost-users] [Serialisation] error with xml_iarchive

I wouldn't expect this work.   Try

  std::ofstream ofs("C:\\Save.xml");
  const wchar_t * ptr;
  ptr=m_strEdit.GetBuffer();
  assert(ofs.good());
  boost::archive::xml_oarchive oa(ofs);
  oa.save(ptr);

  wchar_t *nptr; // note change here !!!
  std::ifstream ifs("C:\\Save.xml");
  boost::archive::xml_iarchive ia(ifs,0);
  ia.load(nptr);
  ifs.close();

For an explanation of why this works (assuming it actually does)
and why your original can't, read the documentation regarding the
serialization of pointers.

Hello,

I just recently began using the boost library, I want to write and read 
string to serialized objects with the function 'xml_oarchive' and 
'xml_iarchive'.
When I execute this code (with visual c++.net v. 7.1) :

  std::ofstream ofs("C:\\Save.xml");
  const wchar_t * ptr;
  ptr=m_strEdit.GetBuffer();
  assert(ofs.good());
  boost::archive::xml_oarchive oa(ofs);
  oa.save(ptr);

  wchar_t str[512];
  std::ifstream ifs("C:\\Save.xml");
  boost::archive::xml_iarchive ia(ifs,0);
  ia.load(str);
  ifs.close();

the programm failed :

Thanks and regards,
