well, i made a static-lib. and i created this three classes in

Connection
http://pastebin.com/Ea9nLFUw

ConnectionFactory
http://pastebin.com/jeAg0cr7

Server
http://pastebin.com/x2ywkKCy

and i drevid from the static-lib and used this classes and it's working perfect

in my main.cpp

 #include <iostream>
 #include "auth_proto.h"
 #include <Server.h>
 #include <ConnectionFactory.h>
 #include "AuthConnectionFactory.h"
 
 using namespace std;
 int main()
 {
 Auth_Setup();
 try
 {
 boost::asio::io_service io_service;
 boost::shared_ptr<ConnectionFactory> fact (new AuthConnectionFactory(io_service));
 Server s(io_service,"5.113.195.156",9959,fact);
 io_service.run();
 }
 catch (std::exception& e)
 {
 std::cerr << e.what() << std::endl;
 }
 
 return 0;
 }

but the Receive() method is not invoking the handle_Receive() method!, can some one tell me what am doing wrong here!!!!???

If you run "netstat -napl -t tcp" when the server is running, does the server show up as listening?
Why are you specifying a specific IP address to the endpoint for listening? Generally, you want to listen on 0.0.0.0 which means "all interfaces."
Also, I seem to recall that your socket needs to be open()-ed before you can pass it into accept(), but I'm not 100% sure.

the client is blocking anyconnection through "127.0.0.1" or so therefor am using an IP, and i dont think there is something wrong with the socket since it's working and the Receive() method is receiving but it's not calling handl_Receive() so i can use this data got me?

In your "Connection" paste, line 77: bytes_transferred is of type size_t (which is always unsigned as per 7.17 and 7.18.3 of the C99 standard)

bytes_transferred <= 0 will always evaluate to false unless bytes_transferred is zero, you probably meant to write if (bytes_transferred > 0)

You should always post the up-to-date code, there was no way to tell you this from anything you showed on stackoverflow.
