[flexcoders] quality=autoLow Cutting off Labels
To help boost performance of a large Flex app, I set the quality of the application to autoLow. I'm aware of the trade-off between performance and graphics, but one Label in particular is sometimes being cut off length-wise. I'd like to keep the quality setting where it is, but is there an attribute I can set on the Label that will consistently display it properly? I set cacheAsBitmap, but I don't know if that's relevant to this problem. Thanks!
[flexcoders] HTTP request error #2032
Hi,
I am using the HTTPService to send POST data to a PHP page in a widely
distributed application. To catch HTTP errors with the fault parameter, I am
assigning a method that takes a FaultEvent as its argument. (this is all
standard).
That fault method writes to a file any time it is entered so as to log the
error. I should also note that I have about 10 of these HTTPServices with
corresponding result and fault methods.
I am noticing in the log file that only one HTTPService is faulting in
particular. Over several hundred thousand (successful) calls to this
HTTPService, a small handful of them are consistently passing the following
FaultEvent message:
(mx.messaging.messages::ErrorMessage)#0
body = (Object)#1
clientId = DirectHTTPChannel0
correlationId = A0C1443E-F9E2-61D7-7FAB-ADD18D4B0675
destination =
extendedData = (null)
faultCode = Server.Error.Request
faultDetail = Error: [IOErrorEvent type=ioError bubbles=false
cancelable=false eventPhase=2 text=Error #2032]. URL: {url here}
faultString = HTTP request error
headers = (Object)#2
messageId = A04FD0F5-8732-1B3B-E253-ADD2572BE01E
rootCause = (flash.events::IOErrorEvent)#3
bubbles = false
cancelable = false
currentTarget = (flash.net::URLLoader)#4
bytesLoaded = 0
bytesTotal = 0
data =
dataFormat = text
eventPhase = 2
target = (flash.net::URLLoader)#4
text = Error #2032
type = ioError
timestamp = 0
timeToLive = 0
I've researched this error and I've gotten many different results. Some say
that it's a bad URL or the URL is too long -- not this case because the
HTTPService succeeds 95% of the time. I've heard other suggestions that the
server itself is to blame -- but the other 9 HTTPServices that call the same
server (even ones that are more heavily used throughout the app) are all doing
fine.
Does anyone know of a reasonable explanation to receive this error #2032? The
way Flex describes this error is completely useless to debug.
Thanks in advance for the help!

[flexcoders] PHP $_POST Array with HTTPService
Hi,
We all know about PHP's ability to send an array through the $_POST
variable, in a form for example:
[form method=POST action=]
[text type=input name=data[name]/]
...
[/form]
But how can I achieve that through Flex's HTTPService?
If I were to print_r($_POST) in the PHP page, this is would I would like
to see:
Array
(
[data] = Array
(
[-1] = A
[0] = B
[1] = C
)
)
I have tried this programmatically while calling the send(params:Object)
method of the HTTPService, with the Object containing {data:
{'-1':'A','0':'B','1':'C'}} but the result is more like [data] =
[object Object]
Any ideas how to mimic PHP's ability to POST an array?
Note: I can achieve this easily with GET, by appending
data[-1]=Adata[0]=Bdata[1]=C to the URL, but my problem requires
POST.
Thanks.

percentHeight is probably what you want, but another way to achieve 100% height

design mode of Flex Builder.

[flexcoders] Smooth Marquee
I tried to scroll images from right to left using DHTML, but the scrolling was choppy and it didn't look right. I want to do this in Flex, but I'm not sure where to start. The application needs to; - take a list of images (maybe in an HBox) - smoothly scroll from right to left - repeat the loop after the entire list has been scrolled This application will be a Flex equivalent of the deprecated marquee HTML tag. Has anyone does this before? Any resources online that you could direct me to? Any tips to get started? Thanks!

[flexcoders] Re: crossdomain with picasa
I don't know how to fix this problem, but I do know of the way to work around it. Simply use HTTPService to call a file on your server (still in your sandbox), which then calls Picasa and does whatever magic it needs to get your data. Even though this is outside of your sandbox, Flex has no idea where your file gets its data from and so it doesn't care about the sandbox violation. For example, you can use a PHP file to connect with Picasa then get whatever data it needs. Then print/echo that data to the PHP page as XML and set the resultFormat parameter of HTTPService to e4x. --- In flexcoders@yahoogroups.com, David Pariente [EMAIL PROTECTED] wrote: Hello, I did a website that gets xml data from picasa website.

If I don't specify the Image component's height and width, the image retains its quality, but it also retains its own unique height and width, and could spill outside of my 175x100 box.

Against what ? How much is the value of the prize ? Who is attacking you ? Why ? Until you answer those questions, how can you evaluate any of the various mitigation's ? For instance, if your attackers are all under 10 (because your app is used in a closed environment, i.e. a school class room, and the login is tied to the attendance list and O/S logged in user) then you probably don't need to do anything else. How can a high score problem be overcome? Some sort of CAPTCHA type test should prove there is a user sat at the computer, but I'm not aware of anyway to verify they're using your client and not another one they built themselves. Given they can intercept your 'calculateChecksumOfYourself()' (or whatever) and just send back the 'right' answer. A lot of the time, raising the bar fairly high (require login, SSL) is probably good enough. In your case, I'd probably want to require unique, verified email address too.

[flexcoders] Flex Control Over Embedded Flash
I know that there is a bridge between Flex and Flash, and Flash SWF and SWC's can be embedded inside of a Flex app. How much control does Flex have over the Flash movie? Let's say I have a component in Flash that has an image in it and a border with a certain color around the component. Is there a way for Flex to dynamically change the color of the border and the source of the image?

[flexcoders] Dynamic HTTPService Request
If I have a variable number of things to POST to a PHP page using HTTPService, I need to use mx:request to get those things over. Is there a way to do this dynamically? Here's the static way: mx:HTTPService ..mx:request var1value/var1 var2value/var2 varNvalue/varN ../mx:request /mx:HTTPService Is there a way to just iterate through a list of values and append it to a list of things to request? I'm trying to POST the flashvars, but there could be many parameters in them and I won't know how many. I need to pass all of them to the PHP page. The way I'm doing it now is to just concatenate them all together, delimited by , and pass the one big string to the PHP page. Can I pass each parameter individually? Ricky
[flexcoders] Re: Securely Interfacing Between Flex and Databases
So the bottom line is to use an algorithm like RSA? To take a much simpler example, if the Flex app receives the encrypted data 1234 and it wishes to use that data, it must first decrypt it. So it performs the decryption in some AS and now you have the decrypted data that you wanted. My question now is, if someone decompiles your app they can see your decryption method and thus decode the data on their own. Nothing is private in the Flex app due to the decompilation concern. Regarding SSL, I suppose this is out of the question if we're talking about a Facebook application. I don't have much control over their security. --- In flexcoders@yahoogroups.com, andrewwestberg [EMAIL PROTECTED] wrote: I think you're confusing simple secret key encryption (DES, AES, etc..) with public/private key encryption (RSA). In secret-key encryption if an attacker steals the data and guesses or brute forces the secret key, they can see the data. In public/private key encryption, a message you send to the server is encrypted by a public key and can ONLY be decrypted by a private key known only to the webserver (the certificate you bought from verisign, thawte, etc...) This is how when you sign onto paypal or some other site over https, you don't have to worry about your credit-card being stolen in transmission. Sitting in some DB at the company where employees can get at it, you should worry, but during transmission, it's unlikely to get cracked. -Andrew
[flexcoders] Re: Securely Interfacing Between Flex and Databases
Well the concern is that no matter how you choose to encrypt/decrypt information, a Flash movie can always be decompiled and your decryption method is caught with its pants down, allowing users to find out how to view sensitive material that they're not supposed to be looking at. So how are we supposed to move this kind of data in and out of a Flex application without the worry? Does SSL even help? The concern is not the forging of data, but rather the interception and decryption of it. --- In flexcoders@yahoogroups.com, andrewwestberg [EMAIL PROTECTED] wrote: Simply having SSL (https) enabled on your php webserver will help.

Kenny -
Your component needs to be an EventDispatcher... if it is extending an
existing DisplayObjects, then it already is. If not, you can just
extend EventDispatcher yourself. Then your component can notify
parents
etc. by creating an event of the appropriate type and dispatching. For
instance here is an event you could dispatch on change:
//create a change event and notify...
var evt:Event = new Event(Event.CHANGE, true, false);
this.dispatchEvent(evt);
Note: You may or may not want the event to bubble... that will
depend on
whether or not the listener is attached directly to your component (or
one of its ancestors).
If you want to send data out with the click you can create a new custom
event (extend Event) and add your data property... then instantiate
your
custom event type and dispatch one of those instead. Example:
public class MyEvent extends Event
{
public static const TYPE:String = myEvent;
public var eventData:Object = null;
public function MyEvent(data:Object, bubbles:Boolean = false,
cancellable:Boolean = false)
{
super(MyEvent.TYPE, bubbles, cancellable);
this.eventData = data;
}
}
and in your click handler:
var evt:MyEvent = new MyEvent(myData, true);
this.dispatchEvent(evt);
The code that listens for this custom event can just do something like:
//attach to the component and listen for a MyEvent type event
myComponent.addEventListener(MyEvent.TYPE, handleMyEvent, false, 0,
true);
public function handleMyEvent(event:MyEvent):void
{
//handle the event...

[flexcoders] Adding Children to Canvases
I have 7 Canvases, one for each day of the week. When the user wants
to add something to the weekly schedule, it could have multiple days
(Monday and Wednesday, for example). The days to add are in a string
like this: UMTWRFS, where each letter represents a corresponding day
of the week. If the days are just Monday, Wednesday, and Friday, the
string would look like this: MWF.
Here's my problem, I wrote ActionScript to check if a day is in the
string and if so, add it to its corresponding canvas via addChild().
Here is my code:
if (days.search(M)!=-1){
mon.addChild(item);
}
if (days.search(T)!=-1){
tues.addChild(item);
}
if (days.search(W)!=-1){
wed.addChild(item);
}
if (days.search(R)!=-1){
thurs.addChild(item);
}
if (days.search(F)!=-1){
fri.addChild(item);
}
if (days.search(S)!=-1){
sat.addChild(item);
}
if (days.search(U)!=-1){
sun.addChild(item);
}
My problem is that if days is multiple days, only the last day is
added to its canvas. This is very strange since I am using 7
independent if statements. I debugged and I saw the code execute
correctly for all of the days in the string, but only the last one
showed up visually in the canvas. Am I doing something wrong? Any help
is appreciated.
[flexcoders] Re: Adding Children to Canvases
I tried using for loops to iterate through the days string, but that
will not even display any of the days or none will display correctly.
Interestingly, if I reverse the order of the if statements, like this:
if (days.search(U)!=-1){
sun.addChild(item);
}
if (days.search(S)!=-1){
sat.addChild(item);
}
if (days.search(F)!=-1){
fri.addChild(item);
}
if (days.search(R)!=-1){
thurs.addChild(item);
}
if (days.search(W)!=-1){
wed.addChild(item);
}
if (days.search(T)!=-1){
tues.addChild(item);
}
if (days.search(M)!=-1){
mon.addChild(item);
}
then I get the opposite problem and only the first day in the string
is displayed and the last ones are ignored. If there is only one day
in the string, then it displays fine. Help!
[flexcoders] Re: Adding Children to Canvases
Thank you, Gordon! That did the trick. Here is the clone() method I wrote:
public function clone():ScheduleElement{
var clone:ScheduleElement = new ScheduleElement();
clone.setLabels(this.crsDeptLbl,this.crsNumLbl);
clone.x = this.x;
clone.width = this.width;
return clone;
}
One thing to note is that I didn't have to specify override for this
function.

A child DisplayObject can only have one parent, so you can't add 'item'
to more than one Canvas. When you add it to the second one it gets
removed from the first, etc.
You need to implement a clone() method to make copies of your items.

[flexcoders] Re: Setting a label to be the length of a List component
I'm getting some trouble from my application. The length of the last
element in the second list is not being computed, even though it is
written in the XML to do so. If you click on the last element of the
second list, the length of the third list is empty. Then if you click
on the next item in the first list and click on the first item in the
second list, then the length of the third list actually includes the
length of the previous third list. It may sound confusing, but here's
the URL of the app with View Source activated. Check out
assets/BRAINoutput.xml for the file used as input. There are a few
mxml files in my src folder, but CourseSelector is the relevant one.
Can someone take a look at these files and try to see why I'm getting
this peculiar error?

I solved the problem in a brute force method of counting iteratively
during the process of compiling the XML file and writing out the
length tag before each major closing tag. This is actually a nifty
technique because accessing the size of a cluster of elements works
just like OOP convention of (something).length - though length is
sometimes followed by empty parenthesis.

[flexcoders] Setting a label to be the length of a List component
I'm using HTTPService to connect to an XML file and use that as a dataProvider to a mx:List component. I'd like to display somewhere in the app the number of items in the List. I've tried everything obvious and I'm stumped. Any help?
[flexcoders] Re: Using an XML file as a dataProvider and accessing its data
That was very helpful, thank you! Two follow up questions. What are the similarities/differences advantages/disadvantages of using multiple Lists instead of DataGrid? For example, if the data of the second column depends on the selection in the first column, I found it easier to just make each column into a List and use the index of the selected Item in the list as an index into the XML file's elements and then populate the second List with the new Array. Secondly, an XML file is already essentially in a tree structure, but how can you use the file as a dataProvider for the Tree component in Flex? The method outlined in the previous question of sequentially populating Lists is basically just a makeshift Tree, but I'd like to find out how to actually use the XML file as a provider for the Tree. Thanks again to whoever can help answer these questions. -Ricky --- In flexcoders@yahoogroups.com, Tracy Spratt [EMAIL PROTECTED] wrote: You can do both. Bottom line, the DataGrid requires a list of items. This can be an XMLList or Array, ONLY if you are certain you will not need to update the data items individually. Best practice is to use an XMLListCollection, which is a collection of XML nodes, or an ArrayCollection of item value objects. Each item in the collection produces a row. Given such a list of data items, each row of the DataGrid gets a reference to the data item producing it. You specify which property or attribute in the item goes in which column using the DataGridColumn object. If the value you want is in a top-level property of the item (an attribute or first level child node of an XML item, or a top-level property of the item object) you can specify the dataField. It the value you want is nested deeper in the item object, use labelFunction(). There are many examples available. Tracy
[flexcoders] Horizontal Scrolling List
Hi. I've had the idea to have a horizontally scrolling list, but I'm not sure how to make it using the Flex components. I guess another way to describe it would be like a marquee or a ticker (like stocks on MSNBC). The elements are arranged horizontally and they slide both left and right-ward. Another idea/complication involves a speed/direction control by hovering the mouse over the ends of the list. Does anyone have an idea of how this can be constructed?
[flexcoders] Using an XML file as a dataProvider and accessing its data
I started with Flex a couple days ago and I'm just learning the basics. This shouldn't be too hard to answer, but getting me to understand it would be the hard part! If I have an XML file with parents, children, and siblings (see the example below), how can I link say a DataGrid to a child element, but access its children? Refer to the sample XML file below. Let's call it test.xml ?xml version=1.0 encoding=utf-8? Schedule Semester id='Spring08' Department id='ACCT' name='Accounting' Course id='211' name='Financial Accounting' Section id='DIS01' limit='150' enroll='71' Section id='ACT50' limit='25' enroll='8'/ Section id='ACT51' limit='25' enroll='12'/ /Section Section id='DIS02' limit='41' enroll='23' Section id='ACT56' limit='41' enroll='23'/ /Section /Course Course Section ... /Section /Course ... /Department ... /Semester ... /Schedule From what I understand, one way to get this document into the DataGrid is to create an HTTPService that connects to the XML file and give it an id, we'll call it 'file'. So in the DataGrid we would say dataProvider='file.Schedule.Semester.Department.Course.Section'? If this is the case, how does the DataGrid know what attributes to pull out of the elements and how is this displayed? Let's say I want to do some OOP and make an object for every Semester, Department, Course, and Section. How would I read this data and create the objects? Fields of the objects would be equivalent to the attributes to the elements. Thank you all for the support
