Hi Gerry,
Can you utilize php as a mediator?
Flash<->PHP<->DLL
I think there would be a huge latency, which would defeat the purpose.
The fastest alternative I know would be an socket server on the same
machine as the flash app. The socket server would then handle the
requests and be able to process them natively. Again, there would be a
huge latency compared to a native call.
PHP eg:
<?php
if (is_file("path/To/yourfile.dll")) {
// true; we can proceed
//code to execute dll, format and send results to flash here
} else {
return false;
}
?>
HTH,
Best,
Karl

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.
