Hello,

      I would really appreciate some help with this error:

"Unhandled exception at 0x7c812a5b in Alchera.exe: Microsoft C++ exception:
boost::archive::archive_exception @ 0x0012e5c0."

      I am making a Visual C++ 7.1 / MFC program using Boost for
serialization. The relevant code is as follows:

      // Ecosystem.h

      #include <fstream>
      #include <boost/archive/text_oarchive.hpp>
      #include <boost/archive/text_iarchive.hpp>

      class Ecosystem
      {
      private:
          ...
          friend class boost::serialization::access;
          ...
      public:
          ...
          template<class Archive>
          void serialize(Archive & ar, const unsigned int version)
          {
              ar & this->intMember;
          }
          ...
      };

      // CDocumentDerived.h

      #include "Ecosystem.h"
      class CDocumentDerived
      {
          Ecosystem* ecosystem;
          ...
      };

      // CDocumentDerived.cpp

      #include <fstream>
      #include <boost/archive/text_oarchive.hpp>
      #include <boost/archive/text_iarchive.hpp>
      ...
      CDocumentDerived::Foo()
      {
           std::ofstream ofs("savedmodel.mdl")
           boost::archive::text_oarchive oa(ofs);
           oa & *(this->ecosystem);                         //
******************* exception arises here
      }

      The exception arises during de execution of the instruction marked
with "***************/" in the code.
      Has anybody any idea?
      Thanking you in advance,

      David
