<p>Implement this factory once in your COM server to provide information about the components the server can create. Subclass QAxFactory and implement the pure virtual functions in any implementation file (e.g. main.cpp), and export the factory using the <tt>QAXFACTORY_EXPORT()</tt> macro.</p>

<p>A factory can also reimplement the <a href="qaxfactory.html#registerClass">registerClass</a>() and <a href="qaxfactory.html#unregisterClass">unregisterClass</a>() functions to set additional flags for an ActiveX control in the registry.

<p>Calling this function if the server is not running (or for an in-process server) does nothing and returns true.</p>
<p>Stopping the server will not invalidate existing objects, but no new objects can be created from the existing server process. Usually COM will start a new server process if additional objects are requested.</p>
