Re: [Flashcoders] Asynchronous ExternalInterface Calls From Javascript, possible?
I'm not calling a JS function from flash until the end of this process. It is the beginning of this process that I want to be made asynchronous.

Re: [Flashcoders] Re: Asynchronous ExternalInterface Calls From Javascript, possible?
I can try that, but since flash isn't multithreaded, I'm not sure that
would work. You mean if I had in AS
function calledFromJS():Void {
doSomething();
return;
}
right? I believe the call to that function would still take as long as
doSomething() takes. Unless I misunderstood...

Maybe I am misunderstanding something bu I would think you could set up a
methodology where JS makes a call to Flash, Flash returns something immediately
to JS, then does its stuff with the web service and calls back to JS again when
its done.
Another option is instead of using ExternalInterface you can use the
Flash/JavaScript Gateway
One thing I have went through is rapid calls between Javascript and Flash have
dropped calls. I believe the kit below has a queuing functionality built into
it.
The one I have used is

because it works well with SWFObject

Re: [Flashcoders] Asynchronous ExternalInterface Calls From Javascript, possible?
It turns out that the asynchronous web service call actually takes
some extra time (like 100ms) the FIRST time you use that web service
method. Subsequent calls to that method only take 1ms.
So, this first time you call this function from JS, JS is blocked for
about 100ms
//flash
ExternalInterface.addCallback(service_GetEmails, this, getEmails);
function getEmails():Void {
_pendingCall = service.getEmails(emailIds);
_pendingCall.onFault = function(fault){service_onFault(fault);}
_pendingCall.onResult = function(result){toJS(result);}
}
//JS
myMovie.service_GetEmails();
Subsequent calls are super fast. Not sure why this is. Must have
something to do with some overhead incurred during the first call. I'd
be interested to know the answer.
I didn't realize it was only on the first call that so much time was
taken. I can actually live with that. Otheriwse, the setInterval and/or
setTimeout suggestion would have done the trick.
Thanks

Aren't web service calls asynchronous, or am I missing something? I mean,
you typically have to set up a result function to handle the web service
response. Calling the service should not hold the function.
In any case, I'd expect you'd have to handle this like follows:
//javascript
function call(){
swfObject.call();
}
//flash
function call(){
}
function callBack(){
getURL(javascript:callBack();)
}
//javascript
function callBack(){
//this would be called when the service response is recieved.
}

setInterval is a handy way to break scope.
Have the AS method called by JS set an interval for let's say 10ms, and
then have the method assigned to the interval take care of business.
Javascript will be free and Flash will keep on going.

Re: [Flashcoders] Flash Development on PC vs Mac
I'd say your choice of Mac vs. PC should go well beyond which is better for flash development considering there are major differences between the two. I'd like to challenge the rest of the people on the list not to get into a PC vs Mac fanboy debate and keep this particular discussion to flash development on the two OSs. My only anecdotal evidence is that my wife works for a prominent interactive agency that does a ton of flash development. their entire flash team uses Macs.

Re: [Flashcoders] Flash Development on PC vs Mac
Another question is what environment are your apps served from. For instance, all of our servers are some flavor of unix, running apache, etc. etc. Because of this, using a Mac has helped in that I can exactly replicate the server environment on my machine. Anything that is installed on the server can easily be installed on my machine (because it is unix-based). If your apps are hosted off windows boxes, then you should consider that as well.
