hi, i working on the creation of a co-simulation framework , for that i'm using asio libraries and serialization to send exchange information between simulators, i'm getting a error that say me " invalid argument" but just that, i dont know about what argument is refered =(. some know which could be the cause(s)?thanks

I'm guessing that this is a runtime error, not a compile time error? How do you get the error message? Is it an exception or something else?

here, all the code , in bold i put the part where i call the client part tha have to connect to a server that is already listening open the same port, u will see some functions that are use for the simulator. I really aprecciate ur help. The strange thins is that i can connect to the same server using a external script, i mean, other code where simulator code is not included. thanks #include #include #include "myNull.h" #include "ip.h" #include "udp.h" #include "rtp.h" #include #include #include #include #include <vector> #include "connection.hpp" // Must come before boost/serialization headers. #include #include #include #include "stock.hpp" static class myNullClass : public TclClass { public: myNullClass() : TclClass("Agent/myNull") {} TclObject* create(int, const char*const*) { return (new myNull); } }class_myNull; namespace s11n_example { /// Downloads stock quote information from a server. class client { public: /// Constructor starts the asynchronous connect operation. client(boost::asio::io_service& io_service, const std::string& host, const std::string& service) : connection_(io_service) { // Resolve the host name into an IP address. boost::asio::ip::tcp::resolver resolver(io_service); boost::asio::ip::tcp::resolver::query query(host, service); boost::asio::ip::tcp::resolver::iterator endpoint_iterator = resolver.resolve(query); boost::asio::ip::tcp::endpoint endpoint = *endpoint_iterator; // Start an asynchronous connect operation. connection_.socket().async_connect(endpoint, boost::bind(&client::handle_connect, this, boost::asio::placeholders::error, ++endpoint_iterator)); } /// Handle completion of a connect operation. void handle_connect(const boost::system::error_code& e, boost::asio::ip::tcp::resolver::iterator endpoint_iterator) { if (!e) { // Successfully established connection.

Can you post the exact code that you use to "establish the connection"?
