James, I wouldn't recommend you do any polling or timers to get the data from the ANE to your as3. The ANE C/C++ libraries give your the functionality to fire Events right into the AVM (your as3 code), and you can pick those up.
When the musician presses the key, you should get a MIDI message in your C code. You can then store that message into a buffer of some kind, and fire an Event to let your as3 code know you got something. Your as3 code would then have to call a function to pull back that buffer. I wouldn't use a "Window Process" to collect those MIDI messages. I would launch a new thread on the OS to watch for those messages. You can use a library like gThreads to spawn a new process and dispatch those events. -Nick On Sat, Feb 11, 2012 at 8:11 AM, James Ong <yanlile...@gmail.com> wrote: > Hi, > > I'm have been experimenting on Native Extension by invoke some C function > from AIR application, example "Hello World return from C" was output > on the application. > > In other way, have anyone tried this experiment: > AIR <- Native Extension <- C > > An example, the function in C will detect when a musician depress a MIDI > keyboard, in turn, will capture the key and invoke Native Extension so > it will output to the application.
