c++ - Sending own class as binary data over socket

Hy!

I am trying to develop a Client Server Communication over TCP/IP.
I want to use an own Message class and send this class as binary data over a 
socket.
I want to use stream operators for reading and writing to the stream.

How do I convert a class to binary data to send it?
How do I use a socket and stream operators for reading and writing?

Thanks a lot.

Examples would help a lot:-)

Hello,

you might want to look into the CORBA framework for the passing of 
objects. Using this framework you will not have to worry about socket 
programming.

There should be plenty of documentation on socket programming on the 
net. A good book might be better though.

Regards,
Brecht

I have some code that could be used as a start, but I have to
adjust it to Digital Mars.

There are some questions:
Do you have full control of both ends of the socket?
Do both ends use the same hardware and compiler?
Do the classes that is to be send use virtual methods?
Do the classes have pointers to data, or is it only
POD and arrays?

I think I will just use arrays.

The code would be very helpfull.

Thanks a lot.

On http://www.codeproject.com/threads/Rcf_Ipc_For_Cpp.asp
is a tool to serialize any C++ class and send it over the wire.

Once DMC will be able to deal with Boost this library should
work as well.

IMHO DMC has a good chance to reach this state,
based on the feedback for bug reports.
