[flexcoders] Re: flash builder: how to create an as3 project WITHOUT flex sdk
I may be wrong but I believe this is because MXMLC is used to compile AS projects in Flash Builder and the compiler may change with different versions of Flex.

[flexcoders] Re: Adobe AIR - interimittent online/offline storage (à la Google Gears)
I have a similar setup for an app that needs to pull data from a server at certain times. This is not generally critical so the server stuff needs to fail silently and allow the app to continue about it's business. To do this I wrote a ServerMonitor class that wraps air.net.URLMonitor. With URLMonitor you point it at a URL and the object will poll that URL for availability at whatever interval you set. There is a StatusEvent that will be dispatched whenever availability changes.

[flexcoders] DateFormatter am/pm returning null
This is a really peculiar problem I'm faced with. I'm using DateFormatter to format a date object into a string (of course) but part of my string comes back null every time. The format string is MM/DD/ L:NN A, which should give something like 01/26/2010 4:16 PM. In my AIR app I end up with 01/26/2010 4:16 null however. This happens with every formatter that uses this format string in this app. To test for a bug in the formatter code I made a separate AIR app and had it format the current date (by using new Date() as the date to format) with the above format string and it worked perfectly. This test fails in the original app. So I think DateFormatter is working just fine. If I get rid of the A on the format string everything works fine, I just don't get am/pm. My data is coming from a local SQLite database and, upon examination in the Flex debugger it looks fine. I'm using Flex 3.4 and my format string is coming from a .properties file (date formats are localized). Anyone have some insight?

Subject: [flexcoders] Escaping slashes in a file name in AIR
So this is a problem that's not really a problem yet it is. I think it's
best explained with an example:
A user wants to save a file so we open the save dialog box via
File.browseForSave(). User then selects a folder my folder and types in a
name like my/file/with/slashes.txt and hits the save button.
What happens is AIR interprets this as save a file slashes.txt in the
folder my folder/my/file/with. To me this seems perfectly reasonable and
correct. In fact, I would say this IS the correct behavior. However my
users feel that what should happen is that a file with the name
my/file/with/slashes.txt should be saved out in my folder.
I haven't tested on Windows but on Mac OS using Safari and Chrome the user's
expected behavior is what happens. In Firefox the slashes are converted to
underscores. This leads me to believe that these browsers are all getting
the name back and escaping the slashes.
In AIR I'm not seeing anyway to get the filename and escape it as the select
that is fired when the user clicks save returns a File object with a name
property set to slashes.txt -- that is, whatever is after the last slash.
Does anyone know how to capture the filename and escape slashes or is that
just not going to happen?

This code works perfectly fine, but I've noticed that it will lock the file.
Consequently if I try and replace the file the operation will silently fail!
The same thing doesn't seem to happen using regular Flex within a browser

Is this a problem with AIR or am I doing something wrong? Should I be closing
the file after it's been saved. Should I be doing something with the

[flexcoders] Re: container layout performance: MXML or ActionScript?
While I don't have any cold hard facts about MXML vs AS performance I'd wager
that, all things equal, AS out performs MXML.
As far as my practice, I typically use MXML for layout and do everything else
in AS. Coming from a web dev/HTML background I find it very easy to visualize
a layout written in MXML and feel that any lost performance (which is probably
minimal) allows me increased productivity as a developer.
--- In flexcoders@yahoogroups.com, zaproheeks zaprohe...@... wrote:
Given two almost identical (more on that below) container classes one
implemented in MXML, the other in ActionScript, which one is likely to be
more performant?
I'm not a Flex expert, but I know that even if MXML is ActionScript, there
a number of things that are quite different. For instance, the layout of
components is entirely taken care by MXML while in AS3 we have to do it by
hand. Also binding is much more natural and common in MXML (stuff like
property={object.value}) while typically (at least in my code) I have no
Bindings in my AS3 classes.
Another difference is that if some of the contained objects are affected by
runtime conditions, since MXML hides away how the layout is actually
performed, I end up doing adjustments on Creation Complete event, which will
cause new re-render events. If I had implemented the class directly in AS3 I
could have done everything inside createChildren() and maybe it would have
been more performant?
What's your experience / best practices toward MXML / AS3 containers and
conditional layout?

I can recommend three things as I've been doing a fair amount of debugging
lately:
1) Check out MonsterDebugger for debugging from your release build
2) Try opening your SQLConnection before calling begin(). I think begin opens
a connection but I'm not entirely sure. Also try adding an event listener for
the open event to ensure your connection is being opened as well.
3) How are you building the release build? Recently I'd experienced some
issues related to an Ant build script that targeted Flash Player 10 while the
Flex Debugger targeted 9.0.28. Setting the Ant script to target 9.0.28 cleared
up my problems. Check this article for details:

[flexcoders] Re: multiple filter function of combobox and two checkboxes
While I don't have an example handy I can hopefully put you on the path. First thing, it doesn't matter what controls you are using to set the filter: the filter will function in the exact same way. For CheckBox and ComboBox you pretty much just listen for the change event and filter when the event fires. Another thing to note is that ArrayCollection is basically just a wrapper for Array. So you can easily convert your ArrayCollection to an Array by calling the toArray method and then take advantage of Array's filter method (http://livedocs.adobe.com/flex/3/langref/Array.html#filter%28%29).

[flexcoders] AIR Ant Build Script
So I posted a question about Ant build scripts for AIR a few weeks ago and got
some great answers, so here's another one.
I have an Ant build script that I'm using to build my AIR project. It builds
everything and packages the application just fine. The app runs with no
noticeable problems until you try to do any serialization with a class we have:
ElasticDictionary. This class merely extends flash.utils.Dictionary with some
convenience methods (like length() -- code is below).
I have the [RemoteObject] metadata and this works flawlessly when the project
is run from the Flex Builder debugger. It also works perfectly when the
release build is exported via the Flex Builder Export Release Build... dialog.
So my question is: what am I missing in my Ant build script that Flex Builder
does for me? The class, ElasticDictionary, is in the project's src folder and
I'm using the 3.4 SDK.
Relevant (at least what I *think* is relevant) code below. Thanks in advance
for your help!

I know it sounds straightforward, but I cannot get it to work. --Geoff --- In flexcoders@yahoogroups.com, Muzak p.ginneberge@ wrote: Add a RemoteClass metadata tag to the custom class: Example at the bottom of the article http://cookbooks.adobe.com/post_How_to_keep_the_type_of_your_objects_when_serializ-8323.html - Original Message - From: Geoffrey geoffhom@ To: flexcoders@yahoogroups.com Sent: Wednesday, October 28, 2009 12:45 PM Subject: [flexcoders] SharedObject problem/bug?

What I ended up doing was dumping the config xml from Flex Builder and from Ant
and noticed that the difference was that FB targeted Flash Player 9.0.28 while
Ant targeted 10. Switching Ant to target 9.0.28 resolved the issue. Of course
this raises the issue: why does this work in 9.x but not 10.

So I posted a question about Ant build scripts for AIR a few weeks ago and
got some great answers, so here's another one.
I have an Ant build script that I'm using to build my AIR project. It builds
everything and packages the application just fine. The app runs with no
noticeable problems until you try to do any serialization with a class we
have: ElasticDictionary. This class merely extends flash.utils.Dictionary
with some convenience methods (like length() -- code is below).
I have the [RemoteObject] metadata and this works flawlessly when the project
is run from the Flex Builder debugger. It also works perfectly when the
release build is exported via the Flex Builder Export Release Build... dialog.
So my question is: what am I missing in my Ant build script that Flex Builder
does for me? The class, ElasticDictionary, is in the project's src folder
and I'm using the 3.4 SDK.
Relevant (at least what I *think* is relevant) code below. Thanks in advance
for your help!

SDK_HOME refers to the location of the Flex 3.4 SDK. LIBS_DIR points to the
project's SWC's. LOC_DIR to localization files; PROP_DIR to properties
(.properties) files.

[flexcoders] Re: bytearray.readObject doesn't convert my objects back
Do you think the class being dynamic is causing this issue? I ask because I
have a similar problem with a dynamic class that extends Dictionary. It works
fine in Flash Player 9.0.28 but not in 10.

[flexcoders] Re: Delay / Pause between script executions
You definitely want to use Timer here. When you create a timer you can set the interval for the timer and you can set the number of times you want the timer to execute. Using your example you'd get something like: myTimer = new Timer(5000, 3); This will create a timer that executes every 5 seconds and it will do this three times. Now you need two event handlers to handle the actual code execution. Timer has two events of interest timer and timerComplete. TimerComplete is dispatched on the final execution of the timer (based on how many iterations you set). Timer is dispatched on every other execution. So wire up some event listeners for these two events and you're pretty much in business. The only other thing you might need to know is what iteration the Timer is on. Fortunately Timer has a property, currentCount, that tells you the current iteration. You can access this in your event handler by reading event.target as this will be pointing to your Timer object.

[flexcoders] Re: Does the Embed metatag still work in the latest versions of the SDK?
Using Flex Builder 3 I had to add the leading slash to Embeds when using Ant as
well. I'm pretty sure one of the previous posters is right: it's all about the
paths and FB does some magic behind the scenes (adds a leading slash perhaps?)
that Ant doesn't.

I had the problem which prevented ant from seeing the asset files, and that

I had this problem once and it turns out that when you are using Flex

you build with ant and I had to move some files around so that mxmlc could
find everything. I believe that mxmlc can only see the src path and its sub

[flexcoders] Re: ADOBE AIR: Is it possible to move some files to appStorage during installati
Just had to deal with this myself recently. There is no way to do this during
install which leaves you with a couple of options:
1) Do a test to see if it's the first time the application has been run and
copy the files to app storage
2) Test for the existence of the files in app storage, if they don't exist,
copy them from the app directory.
#1 is basically a more complicated version of #2 so I'll just give you the
quick and dirty #2 version:
This code is in my SQLService class. This is just the class I use to handle
all my SQL stuff.
_dbFile = File.applicationStorageDirectory.resolvePath(_dbPath);
_dbTemplateFile = File.applicationDirectory.resolvePath(_dbPath);
// If the file does not exists in storage or the one in the application
directory is newer, copy it from the applciation directory
if(!_dbFile.exists || (_dbTemplateFile.modificationDate
_dbFile.modificationDate updateDbFile))
{
_dbTemplateFile.copyTo(_dbFile, true);
}
