RE: [flexcoders] Flex Profiler Questions
1. The profiler post on my blog attempts to explain the difference between profiler memory, System.totalMemory and process memory. Profiler memory is the memory attributed to AS properties. The player has lots of other backing objects allocated in System.totalMemory. Fonts and bitmaps have very small AS representations (a couple of slots for properties). They are mostly buffers the player will use to render. 2. It hasn't been proven, but my theory is that some of the memory attributed to XML is due to the string pool growing and not cleaning up properly. I do have confirmation that XML is not fully parsed. Nodes are turned into structures on-demand so the amount of memory used by XML grows as you traverse it. Also keep in mind that the player rarely, if ever, frees up memory pages because they usually end up sparsely populated so System.totalMemory won't always shrink as much as you would think 3. I'd have to see it in context to remember what it means. A method closure is the association of a method with an object. If you see them in the profiler I think they are simply references to methods in a class. 4. UnloadAndStop is not a giant hammer. It simply stops various media streams as well as dereferences the SWF. It does not free up every AS reference to objects in the SWF so it can't just punt a SWF from memory, you still have to clean those references up some other way. A timer that is still on won't GC. An object listening via weak reference will, but I was told recently that weak references don't get GC'd as quickly as other kinds of references.

RE: [flexcoders] Daylight Savings Time issues from Flex to ColdFusion 8.01
Join the club, we have T-Shirts (except it's passing Date from Flex to Java). The last communication we had with Adobe on the issue is that Flash Player on Windows doesn't handle Daylight savings times properly (at least in the UK, and a bunch of other regions in the bug), and it appears the same issue applies to AIR. What I'd love to see, is Adobe allowing us to turn off the daylight savings code completely, and let us handle it ourselves! Gk.

I'm guessing the advantage to using Symbols in SWF's is that the images can be vector bsaed in case the flex is scaled using ScaleX and ScaleY (and my does for the visually impaired). My problem is I don't have Flash and I'm guessing to create symbols I need it? Is there a poor mans Flash app? I just want to somehow embed my vector images inside the SWF correctly.

[flexcoders] PopupWindow dragging and enforcing main app window bounds
First, thanks to Tracy for answering my question about the columns array of the
DataGrid.
My question relates to dragging popup-windows.
It's possible to drag a popup window outside the main application
window's bounds, and if the user happens to release the
mouse button at the wrong moment, the popup window can no longer be
grabbed.
My popup is defined in ActionScript like this:
public class MyPopupWindow extends TitleWindow { ... }
and is instantiated like this:
var popwin = new MyPopupWindow();
var isModal:Boolean=true;
PopUpManager.addPopUp(popwin, this, isModal);
How would I get a reference to the main application window's bounds?
MyPopupWindow instances could be popped up from deep inside nested containers.
Do I keep getting parents of parents until there are no more parents to get?
If I pass this rectangle to the MyPopupWindow constructor, can MyPopupWindow
use those values to prevent itself from being dropped outside those confines,
in the
stopDragging() method that it inherits from Panel, and relocate itself? What
properties contain its its current location relative to the main window's
bounds?
Or do I need to implement this in the class instance that invokes the
PopUpManager.addPopUp method?
Thanks

[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: Question?? Best method for plotting a Moving Average
answer.net SQL database through Web services call to Flex.../answer...
would like to create a new Array based on existing Array of Ticker data..
So I need to create a new Array Collection then loop through and add the date
from the Tickers Array Collection along with the Moving 20 day average of the
Close Price... THEN ( I have not mentioned this ) What I REALLY want is a
Standard Deviation Calcuation against the Moving Average to plot Upper and
Lower Bollinger Bands
Here's my initial guesstimate at building the new 20 Day Moving Average Array
Collection from the Existing Array_Tickers ArrayCollection
[Bindable] public var Array_BBands:ArrayCollection; (new mov avg Ac)
public function bld_Array_BBands():void
{
Array_BBands = new ArrayCollection;
for (var i:int=0;iArray_Tickers.length;i++)
\\ loop through existing Array_Tickers
{
Array_BBands.addItem(Array_Tickers.getItemat(i).date);
if (i=20)
\\ start at 20th row - as Moving Avg is 20 day
{
var mavg_tick:Int = 0;
\\ create variable to hold Moving Average
mvag_tick = Array_Tickers.getItemAt(i).close.valueof();
\\ need to pick up the date of the Array_Tickers
mvag_tick += Array_Tickers.getItemAt(i-1).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-2).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-3).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-4).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-5).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-6).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-7).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-8).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-9).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-10).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-11).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-12).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-13).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-14).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-15).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-16).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-17).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-18).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-19).close.valueof();
var mavg:Int = (mavg_tick/20);
Array_BBands.addItem(mavg);
}
}
}
If that works ( and I have no idea if it will ) then I need to get the Standard
Deviation calcualted somehow. Because the Formula for what I really want as
previously stated is The Bollinger Bands formular or (MA+K*sigma) Moving
Average (20 period) + or - depending if it's upper or lower (2 * sigma) Sigma
is the Standard Deviation, and I am fairly certain that actionscript does not
calculate the Standard Deviation, so I'll need to do that somehow and I have no
idea how to do that...
This is a lot for me, and I don't expect you or others have the answers but I
need to get the Std Deviation caclulated from the Mean Value above and this is
how to do that...
http://en.wikipedia.org/wiki/Standard_Deviation
I am not sure exactly the best way to proceed, but if anyone has a
suggestions... I guess I would take the difference of each number in the series
above form the mean, divide the sum of the numbers by the count (20) and take
the square root.
It's a brain teaser and I am working on it a piece at a time.
If anyone has a shortcut I'd take it.

will begin at the nth bar where n is your MA period setting. eg.. a 20 day
MA won't start until the 20th day into the data set.
If you're using a static dataset, you could do the calculation in Excel and

There's a lot more than just a moving average and bollinger bands there but
those are parts of it. In order to get this data, we first tapped into a
feed which you have to pay good money for. I believe we are using NxCore
which I think is a DTN product. You might look into that but I know there
are others as well.
For the data, we pass data into a java library called ta-lib:
http://ta-lib.org/
It has methods for moving averages, deviations, etc. We found that the
calculations for our app were simply too intense to be done on the client.
But, we have 5-7 years worth of data that we are looking at for calculations
so you might not run into the same bottleneck we had

So I need to create a new Array Collection then loop through and add the
date from the Tickers Array Collection along with the Moving 20 day average
of the Close Price... THEN ( I have not mentioned this ) What I REALLY want
is a Standard Deviation Calcuation against the Moving Average to plot Upper
and Lower Bollinger Bands
Here's my initial guesstimate at building the new 20 Day Moving Average
Array Collection from the Existing Array_Tickers ArrayCollection
[Bindable] public var Array_BBands:ArrayCollection; (new mov avg Ac)
public function bld_Array_BBands():void
{
Array_BBands = new ArrayCollection;
for (var i:int=0;iArray_Tickers.length;i++) \\ loop through existing
Array_Tickers
{
Array_BBands.addItem(Array_Tickers.getItemat(i).date);
if (i=20) \\ start at 20th row - as Moving Avg is 20 day
{
var mavg_tick:Int = 0; \\ create variable to hold Moving Average
mvag_tick = Array_Tickers.getItemAt(i).close.valueof(); \\ need to pick up
the date of the Array_Tickers
mvag_tick += Array_Tickers.getItemAt(i-1).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-2).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-3).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-4).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-5).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-6).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-7).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-8).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-9).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-10).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-11).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-12).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-13).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-14).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-15).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-16).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-17).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-18).close.valueof();
mvag_tick += Array_Tickers.getItemAt(i-19).close.valueof();
var mavg:Int = (mavg_tick/20);
Array_BBands.addItem(mavg);
}
}
}
If that works ( and I have no idea if it will ) then I need to get the
Standard Deviation calcualted somehow. Because the Formula for what I really
want as previously stated is The Bollinger Bands formular or (MA+K*sigma)
Moving Average (20 period) + or - depending if it's upper or lower (2 *
sigma) Sigma is the Standard Deviation, and I am fairly certain that
actionscript does not calculate the Standard Deviation, so I'll need to do
that somehow and I have no idea how to do that...
This is a lot for me, and I don't expect you or others have the answers but
I need to get the Std Deviation caclulated from the Mean Value above and
this is how to do that...
http://en.wikipedia.org/wiki/Standard_Deviation
I am not sure exactly the best way to proceed, but if anyone has a
suggestions... I guess I would take the difference of each number in the
series above form the mean, divide the sum of the numbers by the count (20)
and take the square root.
It's a brain teaser and I am working on it a piece at a time.
If anyone has a shortcut I'd take it.

How are you receiving your price data to plot? Price feed? Static file?
What you could do is create a function to loop through the array and perform
the moving average calculation and add the result as an extra column in
the array. Are you plotting the full historic price data set? If so, your MA
will begin at the nth bar where n is your MA period setting. eg.. a 20 day
MA won't start until the 20th day into the data set.
If you're using a static dataset, you could do the calculation in Excel
and then save the entire datset as XML and just bring

Hi Steve,
Thanks for the sample code. I was able to come up with something quite similar
to what you have posted.
One question still remains, though. I tried to issue a timer.stop() command
when for example, all the text values have been displayed in the label control,
but the timer event does not seem to stop.
How to specifically stop the timer once all the messages have been displayed?
Thanks.

The source code on this post provides a means to setup recurring timed

every 5 seconds).
Timers in your app... there can be only one.

I'd like this class to have the default styles used by Canvas, plus my own default styles. So I want to get the Canvas CSSStyleDeclaration and copy its properties to a new CSSStyleDeclaration used by my own component (then add my own stuff). I can't see a way to walk through the CSSStyleDeclaration and copy its properties or to separate out the instance so I don't affect all Canvases in the project. Never mind. Found it in the code to CSSStyleDeclaration.
RE: [flexcoders] Re: Does DataGroup support XML?
In Flex 4/Spark, the dataProvider contract is limited to IList implementations
(the Flex framework provides several IList implementations straight out of the
box like ArrayCollection, ArrayList, XMLListCollection, XMLList, etc). We
decided to do this to reduce complexity which in our dataProvider-aware
controls. As part of this, we now don't auto-wrap raw data like Array or XML
into ArrayCollections or XMLListCollections, which is why you need to do that
manually.

[flexcoders] Free Flash :-D
Any Adobe people out there to answer this? I am lucky to work for a University and recieved a free copy of Flex Builder 3. Will there be a same program for Flash Builder 4 and/or Flash Catalyst? Just wondering. Heard a rumor from my Adobe contact about Flash Builder, but was wondering if anyone else heard anything or about Catslyst. Thanks!
Re: [flexcoders] Free Flash :-D
Not directly helpful, but they did make Flex Builder 3 pretty much immediately available to universities (staff and students) once it was released. I had to re-register though, so I have a key for FB2 and FB3. So if history is anything to go by... fingers crossed P.S. I was surprised to find out that commercial use of that license is allowed; that's unlike other Adobe academically-priced products.

That got it quick and easy. Thanks a lot. Marking as solved.

Two ways
1. Add the repeat count parameter to the constructor:
labelTimer = new Timer(5000, messages.length) ;
2. A little math is required (Arrays are zero based and the first event
triggered will have a count of 1. We need to take that into account):
?xml version=1.0 encoding=utf- 8?
mx:Application xmlns:mx=http: //www.adobe. com/2006/ mxml layout=vertical
creationComplete= onCreationCompl ete()
mx:Script
![CDATA[
private var labelTimer:Timer;
private var messages:Array = [This is my first message,
This is my second message,
This is my last message];
private function onCreationComplete( ):void
{
labelTimer = new Timer(1500);
labelTimer.addEvent Listener( TimerEvent. TIMER,
labelTimerTriggered );
labelTimer.start( );
}
private function labelTimerTriggered (event:TimerEven t):void
{
if(labelTimer. currentCount messages.length - 1)
{
labelTimer.stop( );
}
timerLabel.text = messages[(labelTime r.currentCount - 1) %
messages.length] ;
}
]]
/mx:Script
mx:Label id=timerLabel /
/mx:Application

Hi Steve,
Thanks for the sample code. I was able to come up with something quite
similar to what you have posted.
One question still remains, though. I tried to issue a timer.stop() command
when for example, all the text values have been displayed in the label
control, but the timer event does not seem to stop.
How to specifically stop the timer once all the messages have been displayed?
Thanks.
Angelo

Hi Flexcoders,
I know this may sound very elementary but I cannot figure the hell out of
me how to achieve this.
I have a label control. I want to display different messages after every 5
seconds, such as:
myLabel.text = This is my first message
// Need to delay for about 5 seconds here
myLabel.text = This is my second message
// Need to delay for about 5 seconds here
myLabel.text = This is my last message
I cannot figure out how to properly use the pause or timer utilities in
achieving this.
Any idea would be appreciated.
Thanks.

Angelo
