[Boost-users] [asio] Clients (try to) connect only once

10 Feb 2009

      Hi I am writing on a an app, that has clients, which connect, and get events/updates send.

Now, it works almost, but still, I got one problem I couldn't solve sofar:
My Client only connects or tries to connect once. If the server isn't running, I have to restart the app, to be able to try again.
I do get a connection event at the server, but the client seems not to respond to the send data afterwards.

I am not sure, if it might be a threading issue, but i think that calling join() should do the job.

My Code:

void ZMSRClientFrame::OnConnect(wxCommandEvent& event)
{
    // the behavoir happens also with out those 2 ifs (just tried to check that)
    if(inputhandler)
    {
        inputhandler->close();
    }
    if(t)
    {

        t->join();
        t.reset();
    }
    try{
        boost::asio::ip::tcp::resolver resolver(ios);
        boost::asio::ip::tcp::resolver::query query("127.0.0.1", "3210");
        boost::asio::ip::tcp::resolver::iterator iterator = resolver.resolve(query);

        //InputHandler in(ios,iterator);
        inputhandler = boost::shared_ptr<InputHandler>(new InputHandler(this,ios,iterator));
        //ios.run();
        //starting ioservice thread
        t = boost::shared_ptrboost::thread(new boost::thread(boost::bind(&boost::asio::io_service::run, &ios)));
    }
    catch(std::exception& e)
    {
        wxMessageBox(e.what());
        //inputhandler.reset();
    }
    catch(...)
    {wxMessageBox("could not connect");
    //inputhandler.reset();
    }
}

Inputhandler calls async_connect which returns to one of its members. Which works through the first run.

How to solve this?
