This is because MediaElement.NaturalDuration gives you a System.Windows.Duration object (<a href="http://msdn.microsoft.com/en-us/library/system.windows.duration(VS.95).aspx)">http://msdn.microsoft.com/en-us/library/system.windows.duration(VS.95).aspx)</a>, which in-fact doesn’t have a “CurrentState” member. However, MediaElement has a “CurrentState” member, so I think you intending that line to read “ if self.video. CurrentState == MediaElementState.Playing:”. You’ll also need to add “from System.Windows.Media import MediaElementState” to make sure MediaElementState is available.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Let me know if you have any other issues.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div style='border:none;border-left:solid blue 1.5pt;padding:0in 0in 0in 4.0pt'><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> users-bounces@lists.ironpython.com [mailto:users-bounces@lists.ironpython.com] <b>On Behalf Of </b>Andrew Evans<br><b>Sent:</b> Monday, January 11, 2010 1:04 PM<br><b>To:</b> users@lists.ironpython.com<br><b>Subject:</b> [IronPython] Silverlight code need help (Repost)<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I am having problems with my code.
