    <p>Probably the most common easy way wraps essentially your second choice into a template named <code>lexical_cast</code>, such as the one in <a href="http://www.boost.org/doc/libs/release/doc/html/boost_lexical_cast.html" rel="noreferrer">Boost</a>, so your code looks like this:</p> <pre><code>int a = 10; string s = lexical_cast&lt;string&gt;(a); </code></pre> <p>One nicety of this is that it supports other casts as well (e.g., in the opposite direction works just as well).</p> <p>Also note that although Boost lexical_cast started out as just writing to a stringstream, then extracting back out of the stream, it now has a couple of additions. First of all, specializations for quite a few types have been added, so for many common types, it's substantially faster than using a stringstream. Second, it now checks the result, so (for example) if you convert from a string to an <code>int</code>, it can throw an exception if the string contains something that couldn't be converted to an <code>int</code> (e.g., <code>1234</code> would succeed, but <code>123abc</code> would throw).</p> <p>As of C++11, there's a <code>std::to_string</code> function overloaded for integer types, so you can use code like:</p> <pre><code>int a = 20; std::string s = to_string(a); </code></pre> <p>The standard defines these as being equivalent to doing the conversion with <code>sprintf</code> (using the conversion specifier that matches the supplied type of object, such as <code>%d</code> for <code>int</code>), into a buffer of sufficient size, then creating an <code>std::string</code> of the contents of that buffer.</p>

    1. CONice, I prefer Kevin's answer, though as he shows the include and namespace. Just a minor gripe. :) Good job, though!

    2. COI'd say this is the way to go if you don't have C++11 support.

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.
