Apparently, if you load the .swf as a byteArray then you can then use a loader to load that as a swf, in the context of your application. Normally that would be considered a potentially bad thing, but in your case it looks like it could be exactly what you want to do.
Hth. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of John Eriksson Sent: 24 April 2008 09:21 To: Flash Coders List Subject: Re: [Flashcoders] Question about the AIR security model... Yes. I have understood this when doing some research on the subject. My problem though is that I don't want theswfs to be installed together with the app (a few thousand swfs altogether). I want my AIR App to load a dir full of them and walk through them all and check if they implement a certain interface. I've done all these things, my only problem now is that I cannot cast them in AIR at all which makes the whole thing pointless. You see my problem here right? I need it to load arbitrary swfs from a harddrive or network share (i.e locally through the filesystem) and try to cast them to an interface - throw up a warning or generate a list of swfs that do not conform to the interface and need to be fixed. I guess this cannot be easily done, or perhaps not at all... Could it be possible through a sandbox bridge or something like that? /John 2008/4/24 Ian Thomas <[EMAIL PROTECTED]>: > Hi John, > Where are you loading the SWF from? > > I think I had this problem early on with AIR, and it turned out I > was loading from the wrong place.
