I should add that one of the reasons it may not be possible, is the
possibility of calling malevolent code from flash violating the security
sandbox or just code that could crash the flash player/browser itself. I
think Adobe will be reluctant to have a feature that risks sandbox
security or could compromise the flash player in any way. I don't think
Air offers a gateway either, but I may be wrong.

Hi Paul, thanks for the quick response.
The use case would be to call some CPU-intensive audio signal
processing code, most likely written in C++ and packaged as a DLL.
The idea is that a SWF (or AIR app) would try to detect the presence
of the DLL on the user's machine; if the DLL is present, the SWF (or
AIR app) would use the native signal processing functions implemented
in it, otherwise it would rely on a simplified lower-quality
implementation coded in AS3.
I can't think of any way to do what you want. All the native code
workarounds I know of really aren't efficient for real-time calls and
the overhead would outweigh the benefit. Be interesting if anyone
suggests a method.

Hi folks,
Does anyone know whether there's a way to call native code from a
Flash SWF or AIR app, for example to call functions in a DLL?
Something like Java's JNI but for Flash?
I have never heard of anyone doing that and I know of no direct
mechanism to do so.
What is your use-case?
I realize it's possible to read and write local data files from a
SWF (using FileReference) or from an AIR app (using the File
class), but that's reading and writing data, not running code. I
also know it's possible to run C code compiled using Alchemy - but
that's not really native code, as Alchemy-compiled code isn't
native code, but rather byte-code that runs on the ActionScript VM.
