    <p>I have a problem concerning boost asio libraries. I successfully tried to create a socket between a client and a server, this involves creation of resolvers in order to specify ip and port to the server (the server only requires port) and other objects, but, most importantly, it is necessary to use <code>write</code> and <code>read_some</code> as functions to read and write from/in the socket. I would really appreciate to use a stream, and this is possible in boost asio, but that's strange... In almost all examples using streams, to create a server it is necessary to provide port, ok, let's talk about the client... client side, it is necessary to use the iostream constructor to specify coordinates for connecting the stream, here's the code:</p> <pre><code>tcp::iostream() s(argv[1], "daytime"); </code></pre> <p>Well, I don't really understand what is passed in the first parameter and really don't know what daytime might ever represent... Basically, here, I'm telling: "Hey stream, you must connect to this server..." but how can I specify ip and port of that server? Note that, on the opposite, everything is almost clear server side:</p> <pre><code>boost::asio::io_service io_s; tcp::acceptor acc(io_s, tcp::endpoint(tcp::v4(), 1950)); for (;;) { tcp::iostream stream; acc.accept(*stream.rdbuf()); stream &lt;&lt; "Message" &lt;&lt; std::endl; } </code></pre> <p>Using this model, I would like to use</p> <pre><code>stream &lt;&lt; mymessage_to_send &lt;&lt; std::endl; stream &gt;&gt; a_string_containing_my_message; </code></pre> <p>in order to send and receive. How can I do this? Thank you very much.</p>

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
