Re: [flexcoders] FW: Flash Videos & Download Video Link in Real Player ?

[Sid Maskit]

In fact, anybody who is using firebug can use the net tab to see any files which have been downloaded, and can just copy the URL into the address bar to download the video directly. I'm sure there are other ways of doing this too. The basic point is that videos played in the flash player are not protected from downloading any more than are image files such as JPEG's. Sid MaskitPartner CraftySpaceBetter Websites for a Better Worldhttp://www.CraftySpace.comblog: http://smaskit.blogspot.com/- Original Message

No There is not a way you can protect it, even if 
You stop Real Player, there is another Tool SWF Catcher and the person will get 
the video if they wanted.

  Hi All,

  How to protect the videos from

  I am very much shocked to see it

  How does the realplayer checks for

  We are basically using Flash to

  I am very much disappointed with 
  this option can client can easily rip the content. 
   
  Is there any work around for

Re: [flexcoders] Re: how to search an arraycollection

[Sid Maskit]

My understanding of a binary search is that you keep adjusting the floor and 
ceiling. You would need to check to find when floor and ceiling are consecutive 
items. At that point, you would only have two items, and you could run a 
comparison to see which is closer to your target number.

Re: [flexcoders] Data Binding works/does not work

[Sid Maskit]

One more thing on this, since it only sets the binding to nbItems if that is 
done before the XML parsing, you could hack around the apparent bug in the 
following ugly manner:



This sets the binding without affecting the string that is ultimately returned 
to the text attribute.

Hi,

with the code below I experience some strange behaviour of the data
binding - at least it does not work the way I want. :)
There are two text fields each saying 'Cart' plus the number of items.
Then there are two buttons: one will increase the number of items and
the other will switch the language (so the second text field will
either say 'Cart' or 'Wagen').

Now - when I press 'add item' the number of items will just change in
the first text field. In the second text field the number of items
remains 0 - until I press the second button to switch languages. So
why is that? Is it because of the filter I use in the second text
field? Or is it simply a bug?

Re: [flexcoders] storage directory debugging AIR in FLEX3

[Sid Maskit]

Although there are no doubt exceptions, in general you want to avoid using full 
paths, and instead use the handles provided by the AIR environment. That way 
data will be put in the right place regardless of which operating system the 
application is installed on.

On the same machine, the handle will point to the same place in the filesystem 
for both debugging and release versions, except that the file for the 
application itself will be slightly different. The debug version will just be 
the name of the application whereas the release version will contain some sort 
of unique id (which I'm not sure how AIR generates although I would guess that 
it is related to the certificate used to sign the release version).

So for example, I have a hello world application. When I am in debug mode, I 
store my local data here:

C:\Documents and Settings\[my username]\Application Data\AIRHelloWorld

But the release version is here:

C:\Documents and Settings\[my username]\Application 
Data\AIRHelloWorld.1A63E0D1F441D84D82E5395BB5C59EA19782A4AD.1

See the air documentation on the available file system handles, and where they 
point.

Sorry, if this is a newbie question, but I google'd about it, and I

storage directory to write files (windows)?. Once the application is 
compiled and installed, the default directory is something like: 
C:\Documents and Settings\UserName\ Application Data\Test.XXX\ Local 
Store\ (windows xp). But what if I'm only debugging the app?

Thanks in advance!




  

Re: [flexcoders] Data Binding works/does not work

[Sid Maskit]

It works if you switch the second text field so it looks like this:



So it seems as though somehow the compiler gets confused by the deeper XML 
parsing, and bypasses the subsequent binding call. Maybe somebody else has a 
better explanation, but it looks like a bug to me.

Re: [flexcoders] Can the browser embedded swf invoke the installed AIR app?

[Sid Maskit]

Maybe somebody has a workaround, but I'm pretty sure that checking what is 
installed on the local file system is exactly the sort of thing that the 
browser's sandbox is going to keep you from doing.

An imperfect, but relatively simple thing to do would be to set a cookie 
(whether browser, flash, or both) when a user downloads the AIR application. 
You can then have the browser version look for that cookie. Obviously, all this 
will tell you is whether the user tried to download the AIR application, not 
whether they succeeded in doing so. There are probably some other shortcomings 
to this approach, but it might get you a fair amount of the way to where you 
want to be.

Note that the cookie approach actually has an advantage over the approach of 
registering users because you are interested in a specific client machine--the 
one on which the AIR application is actually installed--not in a user who might 
be on any number of machines.

Hope that helps,

Re: [flexcoders] Re: Changing Parents

[Sid Maskit]

I may be wrong, but I have a guess here.

First, you should not need your calls to removeChild. If you take an item that 
is currently in the display list, and use addChild to put it somewhere else in 
the display list, flex will automatically switch its parent from the old one to 
the new one.

My guess is that this is what is happening: "subcomponent. addChild( 
imageViewer) ;" is doing what you wanted to, but "app.removeChild( imageViewer) 
;" is then removing the imageViewer from the display list so that it disappears.

Try just removing the calls to removeChild.

Forgive me, but how do you remove the child from the stage?  Did you 
do the following (using my example):

//Go to full screen
app.addChild( imageViewer) ;
subcomponent. removeChild( imageViewer) ;

//Go to normal screen
subcomponent. addChild( imageViewer) ;

The problem I am having is putting the imageViewer back into the 
subcomponent.  It does not reappear in the subcomponent.

Re: [flexcoders] XML Document and Navigation

[Sid Maskit]

If you have to perform basically the same operation at each level of your XML, 
one way to deal with an open-ended number of levels is to use recursion.

I apologize for not saying more, but I am running out the door, and don't have 
time to write up any kind of sample code on this. However, I'm sure that if you 
google for things like recursion or recursive function, you should find lots of 
information on how this approach works. I'd also guess that Wikipedia has a 
good article on this.

Hope that helps,

Subject: [flexcoders] XML Document and Navigation


Hello Everyone,

I run into a problem, something that probably a lot of people here knows how to 
solve.
But after sitting for 2 days building nestes for loops, i can't see the light 
by the end of the tunnel :-)

So, here is a problem:

I have to build an xml based navigation, so far, quite simple and clear. Made 
it already a few times,
but, now, this is a bit more complicated, because i got a much deeper nested 
sub levels, and i really
don't know how to efficient traverse the document and build the navigation out 
of it :|

The most complex navigation i made had 2 levels, so it wasn't really hard to 
imagine the code for this task:
2 for loops done the nav creation and that's it, but i got now, an "undefined" 
deep, and i don't know how to
bite the code that will build the nav, that goes a bit deeper then one-sub 
level.

Do you guys got any examples or thoughts on how to solve the task?
Im pretty sure that i got an logical error in my approach, since i will use 
some nested for loops, but i can't
think the "formula" since i don't know how deep each of the nodes goes, and 
this task gives me headaches.

any kind of help and pinpointing to right direction would be VERY appreciated

cheers,
Patrick

Re: [flexcoders] Multiple Builder instances / windows?

[Sid Maskit]

I don't know much about eclipse so I have no idea if there is a good way to do 
this. I'm pretty sure this is not the answer you would like, but one way to do 
this would be with virtualization. If you are running a Windows box, you can 
use Microsoft's free virtualPC program.

I'm not sure whether you would run into problems with trying to use the same 
license for multiple copies this way. In theory, it should be okay since they 
are all on the same machine, but since each virtual PC instance appears to be 
its own machine, the license enforcement mechanism might object.

Re: [flexcoders] NaN and Infinity showing in output - How to modify?

[Sid Maskit]

"Eww," eh? Well, gee, Tom, I hope I didn't spoil your breakfast or anything ;)

I think both your refactorings are good ones. I was definitely in "how do we 
get this working" mode, not "how do we get this as elegantly written as 
possible" mode: i.e. I was in code-writing not refactoring mode. So I suppose I 
shouldn't complain about you pointing out a bad smell coming from the code 
writing.

Having said that, I have to admit that I am not at all clear as to protocol for 
how much ActionScript is acceptable within braces while assigning to an MXML 
attribute, or whether there are accepted standards for this. I have the fear 
that this might be a religious question, but maybe not. If there are accepted 
protocols, I'd love to hear what they are.

Just to help clarify things, I'm wondering whether you have any objection to 
ternary statements, or if you do just feel that this is too much code to have 
within an attribute assignment. For example, would this satisfy your objection:

Re: [flexcoders] problem adding images to UIComponents using AS3

There is probably more to it than this, but note that the action script 
language reference listing for UIComponent says, "The UIComponent class is not 
used as an MXML tag, but is used as a base class for other classes."

My suspicion is that it does not contain the logic needed to properly display 
children that are added to it, and that its descendents provide this logic.

I don't get why this code is failing, it's reproducible if you put an image in 
the path shown below.  (This isn't the actual code in my app, I just isolated a 
problem and made the problem reproducible it here.  In my real app, it's 
failing to embed an image into a class that is added to a UI component. The 
class extends Sprite). 
The first Image class instance declared with MXML embeds the image just fine. 
The second, using a UIComponent and adding an instance of the image class to it 
fails. Why?  See comments in the code below:

Re: [flexcoders] Re: NaN and Infinity showing in output - How to modify?

True. Good point. Event handler attributes are assumed to contain code. Most 
attributes are of a type like string or number, and will need braces to get a 
value treated as code. I'm not sure if there are other attributes beside event 
handlers which are also assumed to contain code, but it wouldn't surprise me if 
there are some others.

In at least some instances, MXML will run code that is not within

It's not treating the text within the itemClick property as a string,

but you don't ALWAYS have to enclose your as expressions in brackets 
to get them to run.

I think I see your point here, and I guess that I have not made mine clearly 
enough, so here is a little more on this.

When we say text="{myNumber}", we are really setting up whatever is within the 
braces as an event handler for the event dispatched whenever myNumber changes. 
If we think of binding as setting up that relationship, then yes, everything in 
this thread is using binding. However, I think it is common for beginners to 
think of that statement as binding the text attribute to the latest value of

I think it is important part of learning flex to realize that one can do much 
more than that. In the largest sense, one can do almost anything that is 
possible with a single ActionScript statement, so long as it returns a valid 
value for the attribute to which it is assigned, in this case the text 
attribute. For example, one could do something rather complicated, like this:

text="{(myNumber != 0) ? myFunction() : myOtherFunction()}"

So long as both functions returned a value that could be validly assigned to 
the text attribute, this approach is valid, and we can obviously do any valid 
ActionScript within either function. I'm not sure that this approach would be a 
best practice, but the point is that we are doing a lot more than simply taking 
the value of myNumber and assigning it to text.

Finally, although I do not think you meant to imply this, I think it is worth 
saying that one cannot use ActionScript within an assignment to an MXML 
attribute without using braces. Well, one can, but it will be treated as a 
string, not as code to be run.

The braces actually _are_ executing a binding here, as they will do 
something different when the value of the variable changes.  If the 
value was not expected to change, you could do the same without the 
braces.

Subject: [flexcoders] SQL crashing program


I have this weird deal going on right now.  I'm running through a for loop
creating a bunch of sql statements (within an exclusive transaction) with
eventlisteners for the results and errors.  The result eventlistener is
relaying the status of the progress through the sql statements ("record x of
y inserted").  The program crashes when I run the program, but when I put
code in the result eventlistener to write sql.text to a file (trying to see
if there is a bad sql statement crashing the program) it stopped the program
from crashing and everything works well.  I don't understand why that would
be.  The only thing I can think of is that there is some timing issue that
I'm skirting around with writing to a file in between each sql statement.
Does anybody have any idea why putting the code to write to a dblog file
would make the program work?  I'm sure it's is just that piece of code as
well.  Comment it and it crashes, put it back and it works.

Weird.

Re: [flexcoders] NaN to return a string?

[Sid Maskit]

Sure, just replace the 0 with whatever text you want, putting it inside single 
quotes since the entire statement is inside of double quotes. Since you are 
setting the value of a label, what ever you put in is going to be cast to a 
string anyway.

If the format function is a custom function you have written, you could just 
have it check whether you like the result it is about to return, and if not, 
return something else. If that is not the case, I believe that you should be 
able to put tests into your binding statement. 

You could test for NaN with something like this:

Re: [flexcoders] NaN and Infinity showing in output - How to modify?

[Sid Maskit]

Actually, if you are just going to hide the label field, you can just have it 
display the result of the formatting, and put the checking for NaN and infinity 
into the setting for visibility. Since you are going to hide the label and it 
has a value you don't like, you don't really care what it is displaying when it 
is invisible.

I seem to have trouble explaining myself here, hard when you are just
learning. Perhaps this will be better.

Is it possible to remove, change or hide any label or text output that
displays NaN or Infinity?

I'm performing a very simply calculation where the user enters a
number in a form and it is calculated and displayed. Simple and does
what I need. In some instances, there are more variables required and
until they are provided, the output display NaN or Infinity. 

How could I easily adjust these? It could be a default display of
zero, it could be to display nothing, whatever is the easiest and most
straight forward method.

Below is only an example of how I'm taking the user input from the
form and passing the variable on to the Label text output.

{Number( userInput. text) * (1 +
Number(otherUserInp ut.text)) * 1 /
Number(otherOtherUs erInput.text) }

The answer is output to:

Re: [flexcoders] popup window

[Sid Maskit]

Two things. First, a label can only display a single line. If you want 
multiline text, you should use a Text component. Second, Text components 
automatically wrap if, and only if, they have their width set. I believe you 
can set it to a percentage, and it will still wrap, but you have to set it to 
something.

On a side note, this may seem like a hack, but how else can the system know 
what it should do?

Send the component name, method and arguments list to a generic service method
that does the invoke for you.
And be sure to check that the object name and method are at least members of a

Re: [flexcoders] Interesting problem: dynamically creating id's and later referencing them.

[Sid Maskit]

My understanding is that id's get converted into public variables. Probably the 
easiest way to do what you are trying to do here is to set up a variable in the 
ActionScript, and assign your new Text object to it. Then you can just use that 
variable when you want to access the object. With this approach, the first part 
of your script would look like this:

import mx.controls.Text;

private var myChild:Text;

private function addMyChild():void {
myChild = new Text();
myChild.text = "Hello World!!";
myChild.id = "kid1";
myChild.name = "kid1";
myChild.uid = "kid1";
myPanel.addChild(myChild);
}


If you need to have references to multiple components, you could store them in 
an array.

Hi Guys (and Girls),

Ok, so I have been fighting a couple of days to figure this out. 

In order to make a large and compliated form with drag and drop in of 
more form fields I want to dynamically add an id to an display 
object, and then be able to reference it later to get data out.

Somehow it only seems possible to find these objects by navigating 
trough the the displaylist, and I cannot assign any 'real' id to a 
newly created child.

The following example should illustrate what I want to do (it should 
run). You will find it quite imposssible to get the object by it's id 
(or uid). 

Why is that?? Is there any other way of referencing an object of 
which you do not know who his parent is?

Thank you in advance and greetings,

Re: [flexcoders] Form Processing in Flex

[Sid Maskit]

I'm not sure if I am understanding your question, but maybe this will help. 

Flex can communicate with a server in several ways.

One way that flex can communicate with a server is by pretty much acting the 
same as a browser: i.e. it can submit get and post requests which will look 
exactly the same to the server as get and post requests submitted by a browser. 
Thus you can probably process form submissions on the server using exactly the 
same PHP code that you are using for browser-submitted forms.

Similarly, flex can get the server's response to such a request, and can 
process the provided information. However, unless you are simply going to 
display it to the user, you probably do not want the server to respond with a 
page of HTML, but rather was something that will be useful for flex. Thus this 
might be where you would want to start changing your server-side code to act 
differently for flex as opposed to the browser.

Flex also has built-in classes for communicating with web services, Flash 
Remoting, and LiveCycle Data Services.

One of the nice things about the latter two approaches is that a gateway takes 
care of translating data between flash and the server so that each can work in 
its native datatypes. For example, if one is using a PHP server, the gateway 
will take submitted flash data and convert it to PHP data, and take the 
returned PHP data and convert it to flash data. Thus you can work with native 
datatypes on both the client and server without having to worry about 
conversions.

Obviously, none of the above tells you how to do any of this, but hopefully it 
gives you some starting points for further research, or asking more specific 
questions.

Re: [flexcoders] dynamic remote objects

[Sid Maskit]

ActionScript has two RemoteObject classes. The compiler is telling you that it 
does not know which of them you want to use when you say 'var 
service:RemoteObject = new RemoteObject("ColdFusion");'. From the looks of the 
error message, I would guess that you have a RemoteObject tag in your MXML, or 
that you are otherwise importing the mx.rpc.remoting.mxml:RemoteObject class.

You either need to remove whatever tag or script that is using the MXML version

Ok, I figured out what I was doing wrong but I am still getting an error. I 
think this is the right way to use remote object in AS3 

import mx.rpc.remoting. RemoteObject;
import mx.rpc.remoting. Operation;

// setup the remote method
var service:RemoteObjec t = new 
RemoteObject("ColdFusion");
service.source = component.text;
// the method needs to know about the remote object
var operation:Operation = new Operation(service) ;
operation.name = method.selectedItem .NAME;
operation.addEventL istener(ResultEv ent.RESULT, 
loadGridData) ;
operation.send( );

But I am still getting this error and I am  not sure why? 


Can not resolve a multiname reference unambiguously. mx.rpc.remoting. 
mxml:RemoteObjec t (from C:\Program Files\Adobe\ Flex Builder 3\sdks\3.0.0\ 
frameworks\ libs\rpc. swc(mx/rpc/ remoting/ mxml/RemoteObjec t)) and 
mx.rpc.remoting: RemoteObject (from C:\Program Files\Adobe\ Flex Builder

Send the component name, method and arguments list to a generic service method
that does the invoke for you.
And be sure to check that the object name and method are at least members of a
list you expect to receive, or you risk creating a security problem.

Re: [flexcoders] Running Flex application on Mac

[Sid Maskit]

In theory, flex applications, like flash movies, run the same way on Windows 
and OS X. In reality, there are a number of differences. If you can provide 
details as to what is actually happening differently, including some relevant 
code, somebody might be able to help you out.

I have create one Flex Application, which runs properly on Windows OS.
But same application behaving wrong on Mac. Application loads
completely but while interacting sometime user getting improper response.

So my question is, does Mac need anything to run flex application
properly, or is there anything required on coding side?

Re: [flexcoders] Can SQLite work in non-AIR envirnoment ?

[Sid Maskit]

The SQLite database is part of the AIR architecture, not of flex. So you can 
only use the database in an air application, not in a flex application that is 
running inside a web browser.

If you do deploy an air application, it will provide you with the basic tools 
for synchronizing your data, but does not provide any actual synchronization 
engine. In other words, it allows you to insert into and select from the SQLite 
database, arrange selected data however you wish, and communicate with the 
server, but the actual logic of synchronization is completely up to you. You 
should be aware that this can get quite daunting if you need to allow for 
multiple users to share data and/or each user to store data on multiple 
computers.

I found that a lot of FLEX application used
SQLite. However, most of them is in AIR. Can
it be used in web-based and do sync with server ?

I wanna to design a web application which has data

You're almost right. [Exclude] doesn't affect the compiled code at all - it

Is there a easy way to add a event listener on the UIcomponent rather than add 
them for each

any suggestions?




  

Re: [flexcoders] Sending multiple arguments to a CFC

[Sid Maskit]

You should be able to send multiple arguments by just separating them with a 
comma, like this:

chartmth_RO.qMonthlyUsage( 2008, 04);

By the way, I notice that there is no comma in the sample you provided. 
Assuming that there is a comma in the code you're actually using, what is 
happening when you run it? Are you getting some sort of error? Also, have you 
declared multiple parameters for the CFC you are calling?

Re: [flexcoders] Re: Encapsulating a custom flex component?

[Sid Maskit]

In thinking about this a little more, I have come up with a third way of 
achieving a private sub-component within an MXML-based component. Like the 
others, this is somewhat hacky, but it should work. This one has the advantage 
of allowing you to fully declare the sub-component using MXML. Further, using 
this approach, your other MXML components can bind to the private 
sub-component, although indirectly using what I'm calling a proxy.

Here's some sample code:








Since the textProxy variable is private, and the TextInput control for which it 
is a proxy has no id, I believe that this should create a situation equivalent 
to where there was the ability to mark the TextInput control itself as private.

Hope that helps,

Sid

Re: [flexcoders] Encapsulating a custom flex component?

[Sid Maskit]

I'm not sure whether either of these would serve your purposes, but I believe 
there are two ways to have a private property within an MXML-coded component.

Declare your tree using an MXML tag, but do not give it an id attribute. For 
MXML components, the id is treated as the name of a public property. If there 
is no id, there is no accessible property. Of course, this will only work if 
you do not need to be able to access the tree component at all, but only need 
to declare it: i.e. if you can completely set it up using the MXML, and do not 
need to bind to any of its properties.

Within an MXML script tag, declare a private variable of type Tree. To 
initialize the variable, you will need to have a function do so. Generally, one 
does this within an init function which handles the creationComplete event. You 
could then add the tree object as a child, using the addChild method of the 
component. Within your custom component, you will have access to the private 
variable, but nothing outside of the custom component will have access to it.

What you cannot do is declare as private (or public, protected, or internal) an 
item declared using an MXML tag. By definition, anything declared using an MXML 
tag is public, although not necessarily accessible.

Is it possible to encapsulate (mark private) components within a Flex

So I have custom MXML component (ResourcesTree) that has a Tree inside of it. I 
don't want

One can use the text input control to convert from HTML to plain text, but the

trace(myControl. htmlText) ;
trace(myControl. text);
}

private function onFrame(event: Event):void {
if (done) {return;}
done = true;
trace("from onFrame");
trace(myControl. htmlText) ;
trace(myControl. text);
this.removeChild( myControl) ;
}

To show the change that results from having the control on the stage for a 
frame, here's the trace result:

from init

null
from onFrame
my text
my text

If somebody has a way to have the text input control do the conversion without 
having to put the control onto the stage, I would be interested to hear about 
that.

Hope somebody finds that useful,

Re: {Disarmed} Re: [flexcoders] Variable Typecasting

[Sid Maskit]

Interesting. Thanks for the clarification. I guess I have been thinking that if 
FlexBuilder doesn't show something as an option in the code completion menu 
that I should avoid using it, or should only use it with bracket syntax.

This might just be me, but I would go a little further and say that I like 
using brackets to call out that I am using a dynamic property. On the other 
hand, if I am using a strongly typed object, then I like to cast, and use the 
dot notation. And if I cast first, then the code completion will in fact show 
the property as an option.

So I would want to do something like this:

var vo:VoClass = new VoClass; // some custom class
var obj:Object = {strEMail: "foo"};
var acUser:ArrayCollection = new ArrayCollection();
acUser.addItem(obj);
acUser.addItem(vo);
var strEMail:String = acUser.getItemAt(0)["strEMail"] as String;
strEMail = (acUser.getItemAt(1) as OSData).comment;

Admittedly, as you have made clear, this approach is not necessary. However, I 
do think it has some benefit, particularly since it allows one to both lean a 
little more on FlexBuilder, and give the compiler a little more information to 
work with.

However, having said all that, you are nonetheless quite right that I misspoke 
about what can be done.

There is no reason why 
 
strEMail = acUser.getItemAt( 0).strEMail;
 
shouldn't both compile and run if the 0th
item in the ArrayCollection acUser has a property named strEMail of type
String. And, in fact, I had no problem compiling and running
 
var acUser:ArrayCollect ion
= new ArrayCollection( [ { strEMail: "foo" } ]);
var strEMail:String =
acUser.getItemAt( 0).strEMail;
trace(strEMail) ;
 
It traced "foo" as one would
expect.
 
Since getItemAt()' s return type is Object,
the compiler lets you access any property on it. (Of course, strong typing is
better practice). And when you access a property on an Object, the compiler
treats that property as having type *, which can be assigned to a String var
without casting it to a String.

I haven't worked with the Google API's, so this is a guess, but I suspect that

It has been a while since I worked in C++, but I am pretty sure that you are 
incorrect about references. If I remember correctly, C++ has a distinction 
between pointers and references where a pointer points at a specific memory 
address, but a reference is an alias for another variable, and that variable 
might or might not itself be a pointer. The actual value of a pointer is a 
memory address, but the value of a reference is the value of whatever variable 
it refers to. In order to get the value of the object at the memory address, 
one has to teen reference the pointer. These differences occur because pointers 
and references used different mechanisms.

Like most, maybe all, more recent languages, ActionScript has references, but 
not pointers.

A reference is simply an alias which gives one access to some object. It is 
sort of like a telephone connection to the object: i.e. you can use it to set 
or get the value of the object; but hanging up the phone only breaks the 
connection, it does not make the object go away. You never have access to 
memory addresses.

When an object has no references to it, it becomes eligible for garbage 
collection. There is no way to determine when an object will in fact be garbage 
collected.

Applying this to the system you are describing, things look like this. (For 
simplicity, I will only deal with one of your dates.)

var person:Person = new Person();

Assuming that you are not assigning default values in your class, at this point 
person.breakfast is null.
 
person.breakfast = new Date();

Now person.breakfast refers to the newly created date object: i.e. the date 
object now has one reference to it.

timeArr[1] = person.breakfast;

Now timeArr[1] refers to the same date object as does person.breakfast: i.e. 
the date object now has two references to it.

You could now access the date object by using either reference, and each of 
them would give you the same information, and the same ability to manipulate 
the date object.

However, setting a reference to null, or to a different object, is essentially 
hanging up the telephone, and dialing a new number. This will connect the 
variable you are using to that new object, but has no effect on other variables 
referring to the previous object.

timeArr[1] = null;

Now timeArr[1] no longer refers to anything, but person.breakfast continues to 
refer to the original date object.

Perhaps the key detail here is that what we have is to variables that refer to 
the same object, but those variables have no relationship with one another. 
This is one of the fundamental aspects of how object-oriented programming 
works. I would not say that one could not have a system where having two 
variables refer to the same object would put them into a relationship with one 
another, but only that that would be a very different system from the one we 
have.

Having said that, I would say that you are going to need to have a way of 
directly accessing your person object if you want to set one or more of its 
properties to null.

Re: [flexcoders] Array reference vs values

[Sid Maskit]

It has been a while since I worked in C++, but I am pretty sure that you are 
incorrect about references. If I remember correctly, C++ has a distinction 
between pointers and references where a pointer points at a specific memory 
address, but a reference is an alias for another variable, and that variable 
might or might not itself be a pointer. The actual value of a pointer is a 
memory address, but the value of a reference is the value of whatever variable 
it refers to. In order to get the value of the object at the memory address, 
one has to teen reference the pointer. These differences occur because pointers 
and references used different mechanisms.

Like most, maybe all, more recent languages, ActionScript has references, but 
not pointers.

A reference is simply an alias which gives one access to some object. It is 
sort of like a telephone connection to the object: i.e. you can use it to set 
or get the value of the object; but hanging up the phone only breaks the 
connection, it does not make the object go away. You never have access to 
memory addresses.

Re: [flexcoders] Navigating from flex to jsp page

[Sid Maskit]

Once you've loaded the flex movie, it would seem to me to make more sense to 
treat it as in control, and treat the servlet as a service for the flex movie. 
I would set up a handler for when the servlet returns, and have the servlet 
return some value which tells the flex movie what to do. It could return a URL 
which the flex movie could then navigate to, or it could return an empty string 
in which case the flex movie would do nothing. If you wanted to make it a 
little more secure, you could hard code a default URL into the flex movie, and 
have it navigate there unless it received a message telling it to do something 
else. That way it would default to unloading itself, and would only stick 
around if the servlet told it that was OK.

Hope that helps.

I have a flex application that loads as soon as a user hits a url. Now
this application has a creationComplete method which makes a call to a
java servlet. In the servlet (/servlet filter) I perform certain
authorization checks and if the check fails I want to navigate the
user to a jsp page.

I tried using  the forward method of java's RequestDisptacher class
but once the flex application has loaded this does not seem to work
and the user is not taken to the jsp page. Also I cannot use Flex's
navigateToURL because  jsp redirection is conditional based on
authorization checks in my servlet. Please let me know on how to go
about it.

Re: [flexcoders] Passing variables into your AIR application from a website?

[Sid Maskit]

My suspicion is that there are some serious challenges here.

First, getting the operating system to launch the air application based on 
clicking on a link. I think most operating systems map http links to the 
default browser, mailto links to the default a mail client, etc. There may be a 
way to add new mappings, but I don't know what it is. Unless you can find a way 
for the air application to tell the operating system how to map a link to your 
air application, I don't see how this would work. Presumably, you would need 
something unique about the link which the operating system would use for this 
purpose.

Second, if you did get the operating system to launch the application, it would 
then need some way to pass in the video id to the launched application. I'm not 
sure if there is a way to set up air applications so they receive commandline 
parameters, but I think you would need that, or something like that.

What seems much more likely to work is giving people a text input field where 
they can paste in the URL, and parsing it to extract the video id which the air 
application could then display. Needless to say, it would probably be easiest 
to just give people a video id input field, and include a line in your email 
along these lines: "if you already have the video player application installed, 
enter the following id on the video retrieval screen: idNumber."

Subject: [flexcoders] Passing variables into your AIR application from a

Pardon the cross post

Hello everyone,

I'm hoping someone can advise me on the possibilities of this 
functionality:

I have an AIR application that is used to play videos. I'm storing 
the videos remotely and then calling them through several methods 
defined in my application. The videos are also all located on my 
website for quick access (in the event that a person does not have 
the AIR application installed). Right now, inside my AIR application, 
users can pick their video, and then e-mail it to themselves, their 
friends, etc. When a user e-mails it to a friend, I am simply sending 
the user a link to my website with the appropriate video. I need to 
know if the following things are possible (and to what extent):

1. Is it possible to link directly from any HTML compliant area to my 
AIR application (if the user has my AIR application downloaded), with 
a video directly tied in that link? (e.g. through like a URL 
parameter)

Purpose: This would allow my users to click on 
http://www.mywebsit e.com/my_ Air_app_extensio n/user_video_ id
Which in turn would allow my users to start up my AIR application 
with their video selected instead of starting at the default Welcome 
page of my AIR application.

If you have any other thoughts on how to accomplish this 
functionality, please advise.

Thank you 




  

Re: [flexcoders] Finding a date between dates

[Sid Maskit]

One of the ways that Adobe modified the SQLite database is to have added a date 
datatype. If you use that, I would think that it would also support standard 
SQL such as the between operator. Also,you should be able to read from the 
database field directly back into a date chooser control. Similarly, if you 
then upload data from the local database to a remote database, it should 
correctly map onto a date field in the remote database.

Subject: [flexcoders] Finding a date between dates


Sounds like a simple question and easily answered by a search, but
considering my own "search-fu" and not really finding anything
specifically relating to my question after my search I decided just to
post this.

In the app I'm working on, the user can print out reports by selecting
two dates and getting info on orders placed between those two dates.
How it works thus far is that the user picks the two dates from two
date chooser controls, and clicks the button. How the report itself is
generated and displayed doesn't apply here, I just need to figure out
how to get the info I need from the database.

All my dates are saved in the database(SQL Lite as text) using
something like this:

transactionStatemen t.parameters[ ":dateUpdated" ] = new Date().toString( );

This keeps it in the format the user is most familiar with. However
I'm not exactly sure how comparisons can be done to find a date
between too others since they're not exactly numbers. Basically this
all boils down to, what do I need to do to find all dates which fall
between two selected dates?

Thanks in advance,

In my experience, the compiler gets unhappy when one tries to run code

Re: {Disarmed} RE: [flexcoders] Calling AS3 functions

[Sid Maskit]

I haven't worked much with states, but my sense is that here is how
things might be working.

Either by default, or based on some user action, you are entering the
state where the loginForm component is instantiated. At that point the
user logs in, using the CFC.

By definition, the login process has to be asynchronous. In other
words, you need to make sure that the component which contains the
event handler for replies from the server remains in scope while the
login process occurs on the server.

Assuming that is being handled correctly, you should have a function,
presumably in loginForm, which is triggered by the response from the
server.

I would recommend having that function dispatch a "loggedIn" event.
This would in essence mean that the login form component would be
dispatching that event. Then have the login component listen for that
event, and handle it when it happens.

When dispatching the event, you can include the data received from the
server, and thus that data will be available to the listeners to that
event.

Hope that helps,

Sid

Well, it's pretty flexible. At one end, you can do as suggested below,
and use flex purely as a presentation layer, keeping business logic
and data storage on the server. At the opposite end, you can deploy as
an air application which functions as a pure desktop application with
all three layers on the user's machine. In such a scenario, you could
use the local database and/or filesystem as needed. 

You can do pretty much anything you want anywhere along the continuum
between those two endpoints. Needless to say, once you get into the
world of air deployment, you open up all sorts of possibilities for
distributing responsibilities between the server and local
environment, and for sharing and/or synchronizing data between those
two locales. Although a browser-deployed solution will not have access
to local file system, never mind a local database, it will nonetheless
have a significant amount of local storage available to it. Needless
to say, the security situation is quite different depending on whether
what one deploys is a browser-based application, or an air application.

[flexcoders] Re: Context menu triggers browser crash

[Sid Maskit]

You might try running the same behavior from a simple button, instead
of from a context menu, since that might give you a sense of where the
problem lies: i.e. if it occurs even when you run the behavior off a
button, then the problem presumably has nothing to do with the context
menu.

[flexcoders] Re: Application Design

[Sid Maskit]

Although you could do lots to make this more sophisticated, such as
creating a class for each type of data you are collecting, this looks
like a solid start.

One thing you could do to improve it (which might solve your problem),
is to let the compiler know which variables it should set up for
binding. Like this:

   [Bindable]
   public var client:Object;
   [Bindable]
   public var options:Object;
   [Bindable]
   public var files:ArrayCollection;

Hope that helps.

[flexcoders] Re: GroupingCollection compile error

[Sid Maskit]

Somebody else may see something wrong with the code you posted, but
I'm not. It's unclear from your message where the error is occurring.
Based on the error message, it may well be that the error is in the
code above what you posted. 

I would start by pulling out the code you posted, and replacing it
with a very simple visible element, such as a label or text input, and
see if that makes the error go away. If it doesn't go away, you know
the error is somewhere else in your code.

Well, without seeing more code, I don't think I can say any more than
I already have.

As a sidenote, having proved myself capable of idiocy in infinite ways
when coding, I would advise against ever seriously saying something
like, "I cannot imagine that there is an error in this code."

I have been noticing extra spaces in a lot of posts. I'm suspecting
this is a feature of Yahoo groups, or maybe just of the Yahoo mail

the time you see it):

[flexcoders] Re: Component ClickEvent weirdness

[Sid Maskit]

Given that your compiler error concerns converting a HelpEvent to a
MouseEvent,my guess would be that the problem is that the listener
which is receiving your HelpEvent event expects to receive a
MouseEvent. This is a piece of code which you have not yet shown us:
i.e. the listener function for the HelpEvent.

[flexcoders] Re: TextInputs - no cursor

[Sid Maskit]

After copying and pasting your code, I initially got error messages
for things like "/ >" where there cannot be a space between the two
characters. However, once I fixed all of those, it seemed to work fine
in terms of being able to type into each of the text input fields. I
got the same results whether using a flex app in the browser, or an
air app. I'm not sure where to go from here. Are you sure you are not
getting any compiler errors?

[flexcoders] Re: Setting Up a Global Constants File

[Sid Maskit]

I believe that using singletons is the traditional design pattern way
to do this although I have seen some people arguing that singletons
conflict with unit testing. I don't know enough to comment on that debate.

I would suggest using a getter for your instance so that, at least,
your call could be SingletonClass.instance.myConstant which, at least
to my eye, is a bit easier to read.

Sorry not to be more helpful, but hope that helps somewhat.

[flexcoders] Re: Simple text vs htmlText length question

[Sid Maskit]

Interesting. I didn't look at the documentation before I posted, but I
did run a test case. Having played around a bit more, things are
somewhat convoluted. Here is what I have found:

Whether I use \r or \n, if I assign to the text property, and read
from the text property, the result is a blank line separating the line
with 1 from the line with 2 like this:

1

2

If I use \r to assign to the htmlText property, and read from the text
property, the result is both numbers on the same line like this:

12

If I use \n to assign to the htmlText property, and read from the text
property, the result is what I would actually expect, which is the 1
on its own line, with the number two on the line immediately below it,
like this:

1
2

No matter whether I use \r or \n, and whether I assign to the text or
the htmlText property, if I read from the htmlText property, I get the
same result, which is the HTML equivalent of what I get if I both
assign and read from the text property, like this:

'12'

(Note that I have simplified the HTML by removing things like font tags.)

So I no longer think my explanation makes sense, but I'm not really
sure what does.

Here's the code I used to get these results:

var text:String = "1\r\r2"

var textField:TextField = new TextField()
textField.htmlText = text

var textField1:TextField = new TextField()
textField1.text = text

text = "1\n\r2"

var textField2:TextField = new TextField()
textField2.htmlText = text

var textField3:TextField = new TextField()
textField3.text = text

trace("textField.text : '" + textField.text + "'")
trace("textField1.text : '" + textField1.text + "'")
trace("textField2.text : '" + textField2.text + "'")
trace("textField3.text : '" + textField3.text + "'")
trace("textField.htmlText : '" + textField.htmlText + "'")
trace("textField1.htmlText : '" + textField1.htmlText + "'")
trace("textField2.htmlText : '" + textField2.htmlText + "'")
trace("textField3.htmlText : '" + textField3.htmlText + "'")

[flexcoders] Re: Anyone familiar with CF-Flex remoting?

[Sid Maskit]

This definitely works. Just did it using CFC's.

In MXML:

http://domain.com/flex2gateway/]"; 
destination="ColdFusion" 
source="[path to your CFC here: e.g. folder.folder.file" 
>   




Inside script within same MXML:

this.dataManager.requestAddressChange(this.address0.text,
this.password.text);


Within cfc on server:










You'd need to declare the arguments differently, I think as parameters
within a cfm file, but it should still work.

Hope that helps.
