12//-----------------Introduction----------------------------------------------
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.
