Serialize data to a buffer...

I need a class such as this(just a demo):

class CNetArchive
{
public:
CNetArchive& operator << (int i);
CNetArchive& operator << (float f);
CNetArchive& operator << (string str);
CNetArchive& operator >> (int i);
CNetArchive& operator >> (float f);
CNetArchive& operator >> (string str);
protected:
vector<UCHAR> m_vectorData;
};

It is used to serialize an object to serial data, then send to network, on the other side of network, use this data to create new object.

May I get help from C++ stream library? How to do? Thanks!

If you mean transferring the data from one program to another located on different computers, (e.g. distributed processing) you have several options. The simplest is to just pass the structures via sockets. Other options are com/dcom and cobra.
