Hi:
I am writing some serialization code that uses IOStreams as a filter.
The following is the class I am trying to serialize.
class MIDISurface
{
public:
       // surface variables
std::wstring strSurfaceName;

};
The string header file is included.
I then have a template function as follows:
template <class SerializingType>
void SaveData(SerializingType Data, boost::filesystem::path FileName, bool EncryptData)
{
//Check file existance.
if (boost::filesystem::exists(FileName))
//Delete file
boost::filesystem::remove(FileName);
//Now create a WOfstream to serialize the data.
std::wofstream OutputStream(FileName.generic_wstring());
//Create a filtering_stream to allow us to encrypt the data if necessary.
boost::iostreams::wfiltering_stream<boost::iostreams::output> FilteringStream(FileName.generic_wstring());
if (EncryptData)
       //FilteringStream.push(test); //add the encryption filter defined in Encryption.hpp.
FilteringStream.push(OutputStream);
boost::archive::xml_woarchive Archive(FilteringStream); //create an archive and assign the filtering stream.
Archive << BOOST_SERIALIZATION_NVP(Data);
}
I am including the following headers.
//Standard c++ headers.
#include <fstream>
#include <stdlib.h>
#include <string>
#include <boost/iostreams/traits.hpp>
//boost filesystem headers.
#include <boost/config.hpp>
#define BOOST_FILESYSTEM_VERSION 3
#include <boost/filesystem/operations.hpp>
#include <boost/filesystem/path.hpp>

//Boost xml serialization headers.
#include <boost/archive/xml_wiarchive.hpp>
#include <boost/archive/xml_woarchive.hpp>

//Data type boost serialization headers.
#include <boost/config.hpp>
#include <boost/serialization/string.hpp>
#include <boost/Serialization/Vector.hpp>
#include <boost/Serialization/Map.hpp>
#include <boost/Serialization/nvp.hpp>
//boost io streams header.
#include <boost/iostreams/detail/config/wide_streams.hpp>
#include <boost/iostreams/concepts.hpp>
#include <boost/iostreams/detail/ios.hpp>  // BOOST_IOS.
#include <boost/iostreams/filter/stdio.hpp>
#include <boost/iostreams/operations.hpp>
#include <boost/iostreams/filtering_stream.hpp>
I am using boost 1.47, from the installer from boost pro computing.
Can anyone point in the direction of the solution.
Any help appreciated.
