Hi All,

I'm in the process of constructing a Socket class that uses boost::asio. To start with, I made a connect method that took a host and a port and resolved it to an IP address. This worked well, so I decided to look in to async_resolve. However, my callback always gets an error code of 995 (using the same destination host/port as when it worked synchronously).

code:

Function that starts the resolution:

  // resolve a host asynchronously
  template<typename ResolveHandler>
  void resolveHost(const String& _host, Port _port, ResolveHandler _handler) const
  {
   boost::asio::ip::tcp::endpoint ret;
   boost::asio::ip::tcp::resolver::query query(_host, boost::lexical_cast<std::string>(_port));
   boost::asio::ip::tcp::resolver r(m_IOService);
   r.async_resolve(query, _handler);
  }; // eo resolveHost

Code that calls this function:

  void Socket::connect(const String& _host, Port _port)
  {
   // Anon function for resolution of the host-name and asynchronous calling of the above
   auto anonResolve = [this](const boost::system::error_code& _errorCode, 
           boost::asio::ip::tcp::resolver_iterator _epIt)
   {
    // raise event
    onResolve.raise(SocketResolveEventArgs(*this, !_errorCode ? (*_epIt).host_name() : String(""), _errorCode));

    // perform connect, calling back to anonymous function
    if(!_errorCode)
     connect(*_epIt);
   };

   // Resolve the host calling back to anonymous function
   Root::instance().resolveHost(_host, _port, anonResolve);

  }; // eo connect

The message() function of the error_code is:

The I/O operation has been aborted because of either a thread exit or an application request

And my main.cpp looks like this:

int _tmain(int argc, _TCHAR* argv[])
{
 morse::Root root;
 TextSocket s;
 s.connect("somehost.com", 1234);
 while(true)
 {
  root.performIO(); // calls io_service::run_one()
 }
 return 0;
}

Thanks in advance!
