 185 <h2>wxIEHtmlWin</h2>
 186
 187 The wxIEHtmlWin class is the first example of using a contributed
 188 wxActiveX class in wxWindows C++.  It is still experimental, but
 189 I think it is useful.
 190
 191 <p> Using this class is simpler than ActiveXWrapper, doesn't rely on
 192 the win32all extensions, and is more "wx\'ish", meaning that it uses
 193 events and etc. as would be expected from any other wx window.
