    <p><strong>Delegated Construction Question:</strong> Compiler Error C2039: '{ctor}' is not a member of Logging::LogManager</p> <p>I am using Microsoft's <em>C++ November 2012 CTP Compiler</em>, not the default one in Visual Studio 2012, so I have access to new C++ features, (variadic templates, etc).</p> <p>I am trying to get delegated construction to work using namespaces and header files... I am not certain if this falls under the base constructor inheritance features yet to be implemented in Visual Studio 2012; so, it may be the case that I shouldn't expect this to work:</p> <p>How do you do this in C++ 11?</p> <pre><code>// LogManager.h extract namespace Logging { class LogManager { private: static std::wstring defaultFileName; explicit LogManager(std::wstring logFileName); explicit LogManager(); ~LogManager(void); } // LogManager.cpp extract /******************************************************************** *****/ Logging::LogManager::LogManager(std::wstring fileName) {} /******************************************************************** *****/ Logging::LogManager::LogManager() : LogManager(defaultFileName) // Yields C2664 // : Logging::LogManager::LogManager(defaultFileName) // Yields C2039 // : Logging::LogManager(defaultFileName) // Yields C2614 {} </code></pre> <p>error C2039: '{ctor}' : is not a member of 'Logging::LogManager'</p> <p>error C2614: 'Logging::LogManager' : illegal member initialization: 'LogManager' is not a base or member </p> <p>error C2664: 'Logging::LogManager::LogManager(const Logging::LogManager &amp;)' : cannot convert parameter 2 from 'std::wstring' to 'const Logging::LogManager &amp;'</p> <p><strong>Answer::</strong> Cannot use explicit keyword in header file per known bug already known to Microsoft.</p> <p>Only the first signature will work of the Constructor will work with this .. workaround.</p>

    1. COBoth clang and gcc accept this code. Could you remove VS error codes and replace them with descriptions? Also, **what the heck is [tag:c11] doing here?**

    2. COIt should work (like the 3 version): See http://stackoverflow.com/a/14183972/14065 and it looks like VS2012 should support it: http://stackoverflow.com/a/7422058/14065

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
