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