    <blockquote> <p>How to timeout and throw an exception?</p> </blockquote> <p>Generally speaking, you only get timeouts and cancelability when using asynchronous methods. There are some platform specific ways around this, which have been discussed on SO in previous <a href="https://stackoverflow.com/questions/4553162/c-boost-asio-how-to-read-write-with-a-timeout/4555577#4555577">questions</a>. I strongly suggest you investigate using asynchronous methods, it will make understanding the logic much easier.</p> <p>That said, you can present a synchronous interface by using asynchronous methods underneath. This is done in the blocking TCP client timeout <a href="http://www.boost.org/doc/libs/1_47_0/doc/html/boost_asio/example/timeouts/blocking_tcp_client.cpp" rel="nofollow noreferrer">example provided</a> by the Asio library. Beware however, the example isn't entirely straightforward (albeit, well commented) due to its inversion of control and use of lambda functions. I suggest you investigate using asynchronous methods directly prior to attempting something like this.</p> <blockquote> <p>How to receive 10000 bytes?</p> </blockquote> <p>use the <code>async_read</code> <a href="http://www.boost.org/doc/libs/1_46_0/doc/html/boost_asio/reference/async_read/overload1.html" rel="nofollow noreferrer">free function,</a> the remarks section describes exactly what you need</p> <blockquote> <h2>Remarks</h2> <p>This overload is equivalent to calling:</p> <pre><code>boost::asio::async_read( s, buffers, boost::asio::transfer_all(), handler); </code></pre> </blockquote> <p>where your buffer is 10,000 bytes in size.</p>

A row detail

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.
