What this does is simply to assign each iterated <code>wchar_t</code> to a <code>char</code> - a truncating conversion. It uses the <a href="http://en.cppreference.com/w/cpp/string/basic_string/basic_string" rel="noreferrer">std::string c'tor</a>: </p> <pre><code>template&lt; class InputIt &gt; basic_string( InputIt first, InputIt last, const Allocator&amp; alloc = Allocator() ); </code></pre> <p>As stated in comments:</p> <blockquote> <p>values 0-127 are identical in virtually every encoding, so truncating values that are all less than 127 results in the same text. Put in a chinese character and you'll see the failure.</p> </blockquote> <p>-</p> <blockquote> <p>the values 128-255 of windows codepage 1252 (the Windows English default) and the values 128-255 of unicode are mostly the same, so if that's teh codepage you're using most of those characters should be truncated to the correct values. (I totally expected á and õ to work, I know our code at work relies on this for é, which I will soon fix)</p> </blockquote> <p>And note that code points in the range <code>0x80 - 0x9F</code> in <a href="https://en.wikipedia.org/wiki/Windows-1252" rel="noreferrer">Win1252</a> will <em>not</em> work.

    1. COBizarrely, this works on Visual Studio 10. What is going on? This should cause a truncating assigment from wchar_t to char for all elements of the original string.

    2. CO@PedroLamarão: Why? since it's std::wstring which is template specializing of class 'string' for type 'wchar_t' in STL.

    3. COThe second line above creates an std::string (presumably) from a Range of Iterators, whose value type must then be char. But [wide.begin(), wide.end()) is a Range of Iterators whose value type is wchar_t, whose size is greater than the size of char. I see now that even your source states this is not portable. Perhaps it's Visual Studio specific.

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.
