    <p>Ironically enough, the Adobe Source Libraries has a <a href="http://stlab.adobe.com/classadobe_1_1version__1_1_1capture__allocator.html" rel="nofollow noreferrer"><code>adobe::capture_allocator</code></a> class that was written specifically with this kind of DLL safety in mind. The way it works is to capture the local <code>new</code> and <code>delete</code> at this point it is instantiated, and to carry them both around for the lifetime of the object. (See <a href="http://stlab.adobe.com/structadobe_1_1version__1_1_1new__delete__t.html" rel="nofollow noreferrer"><code>adobe::new_delete_t</code></a> for details on how it does this, especially the implementation <a href="http://stlab.adobe.com/memory_8hpp_source.html#l00674" rel="nofollow noreferrer">here</a>.) Deallocations take place with the captured <code>delete</code> routine, guaranteeing that no matter where you are you are deleting with the proper <code>delete</code>.</p> <p>You can see <code>capture_allocator</code> used throughout the <a href="http://stlab.adobe.com/namespaceadobe_1_1version__1.html" rel="nofollow noreferrer"><code>version_1</code></a> types in the Adobe Source Libraries, such as <a href="http://stlab.adobe.com/classadobe_1_1version__1_1_1any__regular__t.html" rel="nofollow noreferrer"><code>adobe::any_regular_t</code></a> and <a href="http://stlab.adobe.com/classadobe_1_1version__1_1_1copy__on__write.html" rel="nofollow noreferrer"><code>adobe::copy_on_write</code></a>. <code>capture_allocator</code> should be compatible with all STL container types as well.</p> <p>Update: <code>capture_allocator</code> is not standard-compliant because it retains state. This should not be a big hindrance to its usability, but it does mean its use is not guaranteed to work with standard-compliant containers. </p>

    1. COThis is a very common technique, I've seen it in C too where one library requires its users to supply a allocation/de-allocation callback via some kind of library init() point.

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.
