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