<br><br>Yea, an event model is the way to go.<br><br>I still have Authorware hangover, where the reception of an xml file does not necessarily mean it is accessible, i.e. a FileIO status check would tell me the file was received, but it still had to be parsed into a usable xml tree.<br>So I'd loop check until the last element in the xml was available. That way I knew for sure the whole thing was ready to go.<br><br>But as Julian mentioned, SendAndLoad must not fire an event until the parsing has already taken place, so no need for loop checks.<br><br> <br><br>> Date: Wed, 22 Apr 2009 18:21:38 -0400<br>> Subject: Re: [Xerte] Inclusion of close captions onvideofiles anduseofplaylists<br>> From: worldradiolabs@gmail.com<br>> To: xerte@lists.nottingham.ac.uk<br>> <br>> Thanks for the help Dave and Julian, adding an interaction is what I<br>> figured I'd have to do.
