 177 <h2>wxIEHtmlWin</h2>
 178
 179 The wxIEHtmlWin class is the first example of using a contributed
 180 wxActiveX class in wxWindows C++.  It is still experimental, but
 181 I think it is useful.
 182
 183 <p> Using this class is simpler than ActiveXWrapper, doesn't rely on
 184 the win32all extensions, and is more "wx\'ish", meaning that it uses
 185 events and etc. as would be expected from any other wx window.
