Re: [flexcoders] AIR - Ascynchronous file deletion - fixed order ?
You could hold a list (in this case with 2 filenames) that you delete from one by one... just pop an element and refire until the list is empty..

[flexcoders] Questions I always wanted to know the answers to - AsyncTokens
What is AsyncToken and why is it preferred over just calling the Remote Object's method and adding listeners to the method for the result and fault? This class provides a place to set additional or token-level data for asynchronous RPC operations. It also allows an IResponder to be attached for an individual call. What is an example of why you would need to attach the IReponder (addResponser) to a particular method call? Again, I see on another site this In you application you have multiple service calls happening at the same time and you need to know which data coming back belongs to which call.. Calling the same method/service (getPeople) multiple times in the same instance or just calling multiple methods (getPeople, getPlaces, getThings) at the same time? I never had a problem with Flex mixing up the results of multiple methods being called before as a view loads up.. Thanks for any info you can provide.

[flexcoders] Channel.Connect.Failed error NetConnection.Call.Failed: HTTP Status 404
Hi - I found that this error occurs frequently when moving a Flex project from one machine to another. In my situation, I am exporting a release build so another developer can run it on their machine; they don't have Flex, only the flash player to run it. They are receiving this error and the source is a RemoteObject call that points to a service on their machine. So, do I check the web.xml file for their machine? Or the services-config.xml on their machine? I just don't know where to start. Any tips are, of course, very much appreciated. Happy Thanksgiving. Thank you.
[flexcoders] cairngorm store example - newbie binding question
Greetings Flex pros:
In the modified cairngorm store (if you're familiar), file
ProductsAndCheckoutControlBar.mxml, there's:
mx:Image
source={ getProductThumbnailsButton( model.workflowState ) }
That function (getProductThumbnailsButton) is not marked as 'bindable'
so how does the binding happen?
The var model is the only thing marked as bindable in the file.
This is the function:
public function getProductThumbnailsButton( enforceBining : Number )
: Class
{
var model : ShopModelLocator = ShopModelLocator.getInstance();
var result : Class = model.assets.thumbOff;
if ( model.workflowState ==
ShopModelLocator.VIEWING_PRODUCTS_IN_THUMBNAILS )
{
result = model.assets.thumbOn;
}
return result;

[flexcoders] How to tell if a Modal Alert is currently displayed
Hi All, Is there a way to detect if a modal Alert is being displayed if you don't have reference to the Alert instance? I have a bug with a custom popup that is triggered with roll over/out event on an image, basically set a timer check back in couple hundred millis if the mouse is still over(hitTestPoint) and if so display the custom popup. However, at times the application displays an alert and I dont want show the popup if a Modal alert is currently displayed. Currently, there is many areas that are responsible for displaying the Alerts and I am trying to identify a quick and easy way to determine if an Alert is being displayed. When a modal Alert is displayed, does the focus change? Is there some property on my main component(module) that would tell me that it is not the top layer anymore? Any help much appreciated, Greg

that binding to a variable-width component would have helpwed.
Thanks :)
[flexcoders] Re: Questions I always wanted to know the answers to - AsyncTokens
Using an AsyncToken allows you to have only one event listener and one
function to handle all responses from a remote procedure call. You add
some data to the AsyncToken and when the call returns you can check what
the data was and use that to run different code. For example:
myService = new RemoteObject(myDestination);
myService.addEventListener(ResultEvent.RESULT, resultHandler);
var myToken:AsyncToken = myService.getPeople();
myToken.data = getPeople;
myToken.myService.getPlaces();
myToken.data = getPlaces;
private function resultHandler(event:ResultEvent):void
{
switch(event.token.data)
{
case getPeople:
// Do the stuff for getPeople
break;
case getPlaces:
// Do the stuff for getPlaces
break;
}
}
So, if you have a separate event listener and function for each call you
make, then Flex will work just as well. It is just a different way to do
things.
Also note that data can be anything you want like an object or whatever.

Re: [flexcoders] Flex 3: AIR Local Database
The answer to your question about large scale is yes, AIR + SQLite can handle large datasets but with some caveats. I have a SQLite database that is several hundred megabytes. The main tables contain 4 million rows, 275000 rows, and 3500 rows. Queries that join these tables, when the query makes use of indexes, execute in under 100 milliseconds. Snappy. However, some things in the AIR implementation of SQLite are causing index optimizations with the LIKE() operator not to work, both in regular statements and in prepared statements. I am not sure what these things are because the differences between the AIR implementation of SQLite and SQLite proper haven't been documented. They could be things like overloading certain core SQLite functions, or compiling statements/prepared statements with one of the functions that cause the optimizer not to use an index. As a result of these mysterious things, if you run a query like SELECT * from MEMBERSHIP where MEMBER_LASTNAME LIKE 'Johns%' the query will do a full table scan. Do a more complex column value starts-with query that involves joins, and the table scan can translate to very poor performance. For example, when I execute my query at the SQLITE3.EXE command-line, where the index IS used, the query executes in under 100ms but the identical query takes 45-50 seconds in AIR. Also, to keep the front-end responsive when working with large datasets, you will have to use asynchronous data connections not synchronous connections. The coding is somewhat more complicated but also I found the AIR debugger to be less than robust when working with asynchronous connections and data events. However, everything worked OK with Responders, so I'd recommend the use of responder objects over the event-dispatch architecture. I have no experience to offer you with concurrency issues and SQLite. My AIR + local-db application is single-user. Regards TR jwc_wensan wrote: In all the articles I have read and some examples, it only talks about using SQLite as the database on the users' PC/Mac. Is that the only database that can be used locally? Can that database handle a large-scale commercial AIR app with tens of thousands of records? Also, since the AIR app is installed on the users PC/Mac, is there any reason to use mx:Modules? If the user needs/requires that data remain local, is AIR the best solution? Does Flex 4 solve any issues? Thoughts, options, suggestions? Thanks in advance, Jack
[flexcoders] where to get official answer to question about AIR's SQLite implementation and LoadableExtensions mechanism support?
A simple function I need does not exist in the SQLite engine core but the SQLite gurus are telling me to write my own function in C and load it at runtime as a loadable extension. (I have good reasons, BTW, for not wanting the function to execute in the client--it really belongs in the back-end.) http://www.sqlite.org/cvstrac/wiki?p=LoadableExtensions The LoadableExtensions mechanism is disabled by default, and Adobe in its implementation of SQLite may not have enabled the LoadableExtensions mechanism; or if it is enabled, a developer does not know whether it is officially enabled or an undocumented use-at-your-own-risk feature. Where would one get an official answer to the LoadableExtension supported/not-supported question? I've tried the AIR forum at Adobe but my question was not answered there. Thanks

Nope, going to have to loop and create the new array manually. Even using a

This is a pretty well known limitation of floating point numbers. A workaround: http://joshblog.net/2007/01/30/flash-floating-point-number-errors/ Another option around this is to use the toPrecision() function of Number/Int to convert a number to a String and then compare the Strings. var num1:Number = 0.1; var num2:Number = 0.2; var num3:Number = num1 + num2; trace(num3:+num3); trace(is 0.3?+(num3 == 0.3)); trace(num3.toPrecision()+num3.toPrecision(3)); trace(is precise 0.3?+(num3.toPrecision(3) == (0.3).toPrecision(3))); More info: http://www.google.com/search?q=floating+point+math+errors On Wed, Nov 25, 2009 at 5:11 PM, tntomek tnto...@yahoo.com wrote: So to reliably add 0.1 and 0.2 I need to convert them to ints?

RE: [SPAM] [flexcoders] Combo Box Data Grid
This can get little tricky. You need to have an itemRenderer, that when triggered by set data() (actually do the work in commitProperties) loops over the combo box data provider until it matches the current column+line data item value, then sets the selectedIndex of the combo box. Thate are several examples of this available. I have one here: http://www.cflex.net/showFileDetails.cfm?ObjectID=767 It is more complex than absolutely necessary because I wanted it to be generic and reusable.

RE: [SPAM] [flexcoders] cairngorm store example - newbie binding question
The binding mechanism will cause any function to be called if one of its

Bindable really only applies to properties, whether implemented as public

Greetings Flex pros:
In the modified cairngorm store (if you're familiar), file

That function (getProductThumbnailsButton) is not marked as 'bindable' so
how does the binding happen?
The var model is the only thing marked as bindable in the file.
This is the function:
public function getProductThumbnailsButton( enforceBining : Number ) :

var model : ShopModelLocator = ShopModelLocator.getInstance();
var result : Class = model.assets.thumbOff;
if ( model.workflowState ==

Subject: [SPAM] [flexcoders] Re: Questions I always wanted to know the
answers to - AsyncTokens
Using an AsyncToken allows you to have only one event listener and one
function to handle all responses from a remote procedure call. You add
some data to the AsyncToken and when the call returns you can check what
the data was and use that to run different code. For example:
myService = new RemoteObject(myDestination);
myService.addEventListener(ResultEvent.RESULT, resultHandler);
var myToken:AsyncToken = myService.getPeople();
myToken.data = getPeople;
myToken.myService.getPlaces();
myToken.data = getPlaces;
private function resultHandler(event:ResultEvent):void
{
switch(event.token.data)
{
case getPeople:
// Do the stuff for getPeople
break;
case getPlaces:
// Do the stuff for getPlaces
break;
}
}
So, if you have a separate event listener and function for each call you
make, then Flex will work just as well. It is just a different way to do
things.
Also note that data can be anything you want like an object or whatever.

What is AsyncToken and why is it preferred over just calling the

This class provides a place to set additional or token-level data for
asynchronous RPC operations. It also allows an IResponder to be
attached
for an individual call. What is an example of why you would need to
attach the IReponder (addResponser) to a particular method call?
Again, I see on another site this In you application you have
multiple service calls happening at the
same time and you need to know which data coming back belongs to which
call.. Calling the same method/service (getPeople) multiple times in
the same instance or just calling multiple methods (getPeople,
getPlaces, getThings) at the same time? I never had a problem with Flex
mixing up the results of multiple methods being called before as a view
loads up..

Re: [flexcoders] How to get updated value from dataGrid
I usually add a listener to my ArrayCollection.
e.g. collection.addEventListener(CollectionEvent.COLLECTION_CHANGE,
handler);

[flexcoders] How to start learning Flex 4? There is no book out there!!
I am a newbie and want to learn Flex. Now I was told to skip Flex 3 and get into Flex 4 directly. But there is no book available for Flex 4. I can't learn from Flex 4 documentation , I don't even know Flex 3 and how to program. Is Flex 3 that different from Flex 4? I have 3 books on Flex 3 that I purchased today , can I go head and learn from those 3 books then purchasing the Flex 4 books when they will be out?
RE: [flexcoders] MAC : TextInput focus
Are you trying to start the app with focus so you can just start typing? AFAIK
this is only possible in IE. It is a browser plug-in issue. Hopefully newer
browsers will solve this issue.

Julian,
Still the focus is not set:( in the text input filed even after setting
callLater(myComp.setFocus) and more thing is keyboard events wont work, ie. i
mean clicking on tab wont work.Right now i m calling myComp.setFocus in
creation complete event handler.
code Snippet
creation complete event handler
private function init():void
{
/// some action script code here
callLater(this.setFocus);
}
P.N: This happens only in safari browser
Thanks,
Suman
