  13 // This backend is for Desktops with either WMP 9 or 10 and Windows
  14 // mobile (5.0, some 2003 SmartPhones etc.) WMP 10 only (9 has no automation
  15 // interface but you can hack it with message hacks to play through
  16 // a currently running instance of media player).
  17 //
  18 // There are quite a few WMP 10 interfaces and unlike other media
  19 // backends we actually set it to automatically play files as it has
  20 // as huge caveat that you cannot (technically) obtain media information
  21 // from IWMPMedia including duration and video size until a media file
  22 // has literally started to play. There is a hack (and indeed we have
  23 // it within this file) to enable duration getting from a non-playing
  24 // file, but there is no hack I (RN) know of to get the video size from
  25 // a file that isn't playing.
  26 //
  27 // The workaround for this is to send the wxEVT_MEDIA_LOADED when the file
  28 // is about to be played - and if the user didn't change the state of the
  29 // media (m_bWasStateChanged), when set it back to the stop state.
  30 //
  31 // The ActiveX control itself is particularily stubborn, calling
  32 // IOleInPlaceSite::OnPosRectChange every file change trying to set itself
  33 // to something different then what we told it to before.
  34 //
