    <p>I would like to provide an extra boost::function to a async_write. I want the connections own HandleWrite function to be called first and then call the provided boost::function.</p> <p>Member method of Connection that binds to asio async_write</p> <blockquote> <pre><code>void Connection::HandleWrite( const boost::system::error_code&amp; e, boost::function&lt;void (const boost::system::error_code&amp;)&gt; handler) { // Code removed for clarity if(!handler.empty()) handler(e); }; </code></pre> </blockquote> <p>Trying to bind HandleWrite to a asio async_write and provide another bind as the value for handler. This doesn't compile. What am I doing wrong?</p> <blockquote> <pre><code> void Connection::QueueRequest( boost::shared_array&lt;char&gt; message, std::size_t size, boost::function&lt;void (const boost::system::error_code&amp;)&gt; handler) { // Code hidden for clarity boost::asio::async_write(m_Socket, boost::asio::buffer(buffer), boost::bind(&amp;Connection::HandleWrite, shared_from_this(), boost::asio::placeholders::error, handler ) ); } </code></pre> </blockquote> <p>The error message I get from the compiler is the following:</p> <blockquote> <pre><code>Error 1 error C2825: 'F': must be a class or namespace when followed by '::' boost\bind\bind.hpp 69 Error 2 error C2039: 'result_type' : is not a member of '`global namespace'' boost\bind\bind.hpp 69 Error 3 error C2146: syntax error : missing ';' before identifier 'type' boost\bind\bind.hpp 69 Error 4 error C2208: 'boost::_bi::type' : no members defined using this type boost\bind\bind.hpp 69 Error 5 fatal error C1903: unable to recover from previous error(s); stopping compilation boost\bind\bind.hpp 69 </code></pre> </blockquote>

    3. COThe problem turned out to be in another place that used the same HandleWrite function and wasn't bound correctly. After fixing that it compiled.

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.
