I am continue to build two simple processes throwing class objects one to another

  • 0

I am continue to build two simple processes throwing class objects one to another (see my previous post) through simple (anonymous) pipes. Now I revealed for myself boost::serialization (thanks answered people) and have tried to make some class be serialized through ::WriteFile::ReadFile. So – what I am doing wrong?

1) I created some class

 #pragma once  #include 'wtypes.h'  #include <boost\archive\binary_oarchive.hpp>  #include <boost\archive\binary_iarchive.hpp>  #include <boost\serialization\binary_object.hpp>   class CTextContainer  {  friend class boost::serialization::access;      template<class Archive>      void serialize(Archive & ar, const unsigned int version)      {          ar & m_sText;          ar & m_dwCRC;          ar & m_dwSize;      }   public:       CTextContainer() : m_dwCRC(0), m_dwSize(0)       {           ZeroMemory(m_sText, sizeof(m_sText));           m_dwSize = sizeof(*this);       }       CTextContainer(LPCTSTR sText) : m_dwCRC(0), m_dwSize(0)       {          ZeroMemory(m_sText, sizeof(m_sText));          wcsncpy_s(m_sText, 1024, sText, wcslen(sText));          m_dwSize = sizeof(*this);       }       virtual ~CTextContainer(){}       LPTSTR GetText() const{return (LPTSTR) m_sText;}       protected:       DWORD m_dwCRC;       DWORD m_dwSize;       TCHAR m_sText[1024];  }; //end of class

2) And now I am trying to read from this class into binary archive and to write its content to one end of pipe… 

boost::archive::binary_oarchive oa(ofs); oa << tc; ::WriteFile(hPipe, &oa, dwRead, &dwWritten, NULL) == FALSE

It won’t work in that way, right? So, how it will?

3) Same operation on other side?

  1. I think the problem here is that you’re trying pass a pointer the the archive object in the WriteFile function. What you should do instead is provide a pointer to serialized data.

    std::stringstream ss; boost::archive::binary_oarchive oa(ss); oa << tc; ::WriteFile(hPipe, ss.str().data(), ss.str().data().size(), &dwWritten, NULL)

    As a better alternative you should provide the binary_oarchive constructor with an ostream implementation that writes directly into your file handle.
