A little late to this party but this tool is incredible. Being able to examine loaded class names at runtime is amazing. Thanks much!

I haven’t encountered that… the only thing I can recommend is to make sure your fla or swf file isn’t corrupted.

Thanks for the help, I got it working in the normal case but I can’t get working in a certain situation. When loading a SWF compiled normally from an FLA it works fine, but if I try to just export a single MovieClip into a swf and try to load that and find the class name it fails saying “Record header length too big.”.

The main reason for doing this is because I want to split up assets into multiple SWF files but they are all stored in a single FLA, because making a new FLA for each asset swf would just be stupid.

@Jgrant: You can create a loader by using Loader.loadBytes().
That’s what I’m doing in the ExampleMain.as file in the onSwfLoaded function, check it out.

Hey there, this is exactly what I’ve been looking for but I have a question. After you’ve downloaded the swf and gotten the array of the class names how do you instantiate the classes from the loaded swf? Since it was downloaded as a ByteArray instead of just a normal swf is it even possible? Do you have to download it again in the correct format?

Thank you very much, this helped me a lot.

Nevermind - I’ve found the swfdump tool that’s provided with the Flex SDK which does exactly what I need. That is, you can determine which classes any given .swf file depends on.

Is it possible to extend this tool to determine from the SWF bytecode what classes a SWF is dependent upon which it does not define?

That is, if I compile a SWF which references one or more SWC files without static linking, I have a SWF that is dependent on other SWF/SWC files being loaded first.

So the question is, can I determine those dependencies on any given SWF file at runtime without having to resort to the link report? AFAIK, there’s no way to determine this without the link report.

Lol, well, glad it’s fixed =)

That was retarted. Restarting the Flash IDE fixed the issue.
