[flexcoders] Creating a dynamic search interfaces - strategies and suggestions

[David Adams]

I'm experimenting with creating a dynamic search interface and am
wondering about the most effective strategy to use in Flex. I'm
ignorant enough about Flex that I'd guess some of my ideas won't make
sense so I'm hoping to get feedback that will save me from chasing
down too many dead ends.

For this experiment, I'm creating an interface like the Finder's
search in OS X. You start of with one search term and then can add as
many as you like - each on its own 'line'. For those of you that don't
know what this interface looks like, you get a series of (Drop-downs)
static text and [Entry Areas] along with a (-) ad (+) button to add or
remove terms.

(Kind) is (Any) (-) (+)  Where (Kind) can be "Kind", 
"Last
opened date", "Last modified data", and so on and (Any) can be
"Applications", "Folders", "Documents", "PDF" and so on. Depending on
the choice you make - the related options change. For example:

(Created date) is (within last) [  ]  (days) (-) (+) The
exact details aren't too important - the main thing is that:

* You can add any number of 'rows'.

* The type (kind) of query determines what objects appear in the row
and what they contain. (The entry and drop-down contents are driven by
the type.)

* When you add (+) or remove (-) a row, the rest of the objects on
screen move or resize automatically.

This isn't the exact interace I need, but it's a good enough starting
point. Once all of the entries are completed, I'd like to package them
up and send them off magically somewhere for processing using an HTTP
post.

Key point: I'd like some of the options to be data-driven from a
server. For example, the styles of comparison or the kind of searches
may not be something I know until runtime.

If anyone is still reading, and with all of that in mind, I'm
imagining there are a few ways to build this:

* Build one MXML component that has all of the various objects,
presumably wrapped inside of an HBox or Canvas. -- The dynamic values
(popups and so on) are assigned/modified using ActionScript. -- The
objects that should be shown/hidden are configured using AS.

* Build an AS class for SearchRow and pass into the constructor
whatever values are needed to set defaults.

* Build an AS class with a pretty nearly empty constructor and then
assign the various dynamic values from the code that creates the
object.

Since I want to package up all of the various settings, what I need to
be able to do is iterate over the 'rows' or handle them as an array of
objects. Given that, I'd be grateful for suggestions on the most
effective way to manage storing/return references to the objects.

Thanks in advance for any help or suggestions!

Sorry, I'm not meaning to be difficult. The server definitely does not
support AMF and will not any sooner than...not this year. That's why
I've been exploring alternative. Plus, I've spent some insane amount
of time over the last ten years studying messages on the wire and can
get a bit obsessive (read 'stupid') about sorting out message sizes
and round-trip times. I'm hoping to build up a pretty good list of
techniques/technologies to compare and put into a test harness. I
figure I'll end up using Charles to emulate different relevant
bandwidth constraints and it's easy enough to try various payload
sizes + encoding time + decoding times.

You've still managed to avoid telling us about your back-end setup.

Tell us more about that and we could probably be of more assistance.  
No good me suggesting stuff that works for apache on linux to find

I haven't tested it yet in the Flash player but the post I linked to
earlier claimed String.split (native to the player) is considerably
faster than the native XML parser - at least in some cases. That's not
hard to imagine, really. Either JSON or XML are text - both of which
should benefit - even quite dramatically - from compression.

That sounds great and I'd like to pursue this as a few other people
have made the same observation. In my tests, the gzipping wasn't
happing in the browser prior to the data being loaded into the Flash
player. I set the MIME type on the server to "application/gzip" or
similar (I looked up the correct-sounding type at the time.)

Can anyone point me to a working example of gzipping working
'passively' but effectively? Namely, that the Flash player gets
uncompressed data even though the server sends the data compressed.
That would be ideal.

Thanks - it's a great article. The author mentions gzipping but I
haven't found the specifics. I suspect he's comparing processes
without any compression.

RE: [flexcoders] Re: LCDS Upgrade Problems

[Jeff Vroom]

I think this is maybe a problem with the version of hibernate you are using.   
As part of this simplified configuration feature, the assembler is going into 
the metadata for hibernate and it seems like the protection-level on that 
method has changed or is different in the version you are using than the one we 
compiled against.   We are using 3.2.5 I believe.

You should not need to change any configuration as it is compatible with the 
old format.   You can remove the metadata section entirely and it will generate 
the id properties and lazy=true associations for each hibernate association.
You can then add assoc tags as needed to change the defaults.Any associated 
destinations which are not defined are not directly accessible via clients 
though they are created so you don't have to declare all destinations in your 
model - just the ones you use fill or getItem calls on.

Back to the original error, I guess the other spring configuration you were 
using was generating some proxy class which did not extend HibernateAssembler?  
 What version of spring are you using?

That is correct; I have a destination who's source is a derived object of 
HibernateAssembler (Just to shutoff autoRefreshFill). My assember is then a 
bean in the Spring container.

Obviously something is wrong with this bean because if I force CGLib proxies in 
my container (to avoid the proxy cast error; even though my derived assembler 
implements an interface) I get the following error:

Would I need to update my data-management-config.xml file for 2.6? I am under 
the impression that it can be greatly simplified (from 2.5.1 config) by 
removing the hibernate object mappings; but it doesn't need to for backward

I'm trying to develop a UI piece that consists of a HorizontalList using an 
Image control as an ItemRenderer.

Here is the code:

http://pastie.org/408846

For the life of me I cannot figure out how to get rid of a single pixel gap 
that gets put around each Image control. I've debugged a bit, and found out 
that even though the source image is 126px, and I've set the columnWidth to 
126px, Flex is shrinking the Image control to 124px.

I understand that if there was no gap, you would not be able to see the roll 
over tile, but that's my point. I want a continuous strip of images.

Anyone got any idea what is going on here?

RE: [flexcoders] Re: Web service, parameters, errors... Help please

First and foremost, we must know: what is the name of the operation/method
of the web service, and what are the parameters names and datatypes.  I am
not good enough at reading wsdls to offer to analyze yours, but you can
probably figure it out, or find some documentation.

 

For instance, where did you come up with the string,
'Find__CompIntfc__DL_TREE_IB_CI"?

 

Next, decide whether you want to do the whole thing in AS or not.  I often
declare the web service in mxml, then manipulate it in AS.  

 

No, "new GetInfo()"  would not be correct.  Declaring the WebService in
mxml, or calling "loadWSDL" automatically makes the operations/methods
available to the web service instance, no need to "new".

 

Here is a simple example that might help:

I wonder if you would be willing to help me flesh out the function path (As

private function betterway (): void

var sValue:String = "something";
var oRequest:Object ={ Find__CompIntfc__DL_TREE_IB_CI : sValue };

myService.send();

If I try this, I get an error that there is no send() method for GetInfo. If
I switch it to 
myService.findID(oRequest)
I get an error that type Object is being coerced to "possibly unrelated type

Re: [flexcoders] Re: Compressing messages/data: What binary/compression formats are workable in Flex?

[Guy Morton]

I find it hard to believe you are running a back end that's incapable  
of sending AMF. I thought perl was problematic for AMF...but even it  
has a solution that works...so what *are* you using on the backend?  
You running a VAX machine or something? :-)


JSON isn't binary but is more compact than XML. OTOH, parsing it may  
not be as quick as XML.


I wouldn't be manually zipping and unzipping data - a better idea  
would be to enable GZIP on the web server and let the browser do the  
work (not that that is trouble-free but still...).

Nope. I can bolt in zip/unzip and a JSON encoder/decoder - but not  
AMF.


Speaing of which, I think I've asked my question badly enough that no
one thought to suggest JSON. I guess my most general question is:

"What techniques can I explore for reducing message sizes that work
efficiently in Flex?"

As I understand it:
-- AMF is native & fast.
-- JSON is not native & I'm not sure how fast it is.
-- XML is native and relatively fast...for XML.
-- Unzipping is native and fast...but not many methods are supported.
-- Custom binary protocols are fine as long as I draw the data down
into a general object or ByteArray and then parse it myself. Of
course, that means the parser is running in ActionScript - not code
compiled into the player.

Any other ideas?

Thanks, as always, for any suggestions.

Further to this suggestion, I just stumbled across a note from 2007
that claims String.split is about 10x faster than the XML parser -
making delimited ASCII a good solution for (as an example)
transferring name-value pairs:

http://onflash.org/ted/2007/11/apis-with-delimited-ascii-text-vs-xml.php

As noted, gzip compression can reduce the overall message size.

RE: [flexcoders] Re: LCDS Upgrade Problems

[Jeff Vroom]

I am thinking your spring configuration must be wrapping the HibernateAssembler 
in a proxy.   The code is getting an error here:

HibernateAssembler assembler = (HibernateAssembler) 
destination.getFactoryInstance().lookup();

when trying to use the factory to get the assembler component from the 
destination.   Usually when you generate a proxy though, it would extend the 
class being proxied?Does that make sense as to what is going on?   Maybe we 
need to unwrap that proxy in the SpringFactory...

I should also have mentioned, the source for the hibernate assembler is in the 
product.   It in resources/samples/assemblers in flex-messaging-dist-src.zip.

[flexcoders] HorizontalList ItemRnderers Mysterious Horizontal Gap

[adamduro]

I'm trying to develop a UI piece that consists of a HorizontalList using an 
Image control as an ItemRenderer.

Here is the code:

http://pastie.org/408846

For the life of me I cannot figure out how to get rid of a single pixel gap 
that gets put around each Image control. I've debugged a bit, and found out 
that even though the source image is 126px, and I've set the columnWidth to 
126px, Flex is shrinking the Image control to 124px.

I understand that if there was no gap, you would not be able to see the roll 
over tile, but that's my point. I want a continuous strip of images.

Anyone got any idea what is going on here?

I typically create a static class to use for the RemoteObject.  Each custom 
typed object in the collection has a reference to it and a method that can be 
called to tell it to load children.

The dataProvider for your ADG will always be a HierachichalCollectionView, 
which means you can easily get from parent to child and vice versa.

If you start out with an empty ArrayCollection as the children property on each 
of your objects, then when that AC is updated (NOT REPLACED) by the result of a 
Remote Object call, then the AC should generate whatever events the ADG needs 
to fill itself in.

[flexcoders] Is there a way to detect mouse button state without tracking events?

[Dave Kong]

I need to find out at this particular moment, if the mouse button is up or down.

Trying to work around the issue with wmode=transparent in FF. If I scroll a 
list, and drags cursor outside of the player and then releases the button. That 
mouseUp event is never captured by Flash Player, so when I move mouse cursor 
back, buttonDown is always true for all mouse events.  So I need a workaround 
on moues re-entry to detect if button is truly down, if not, call the 
scrollThumb's releaseButton function so it won't keep on scrolling.

Thanks!

[flexcoders] DataGrid ItemRenderers and display text highlighted search text.

[Todd]

Hello All (probably one for Alex H),
 I know I've seen this implemented before somewhere around the web, but I've 
search for awhile and can't find it.

I have a custom DataGrid that I've subclassed and do lots of trick 
functionality on it.  I pass it a search string, and only the rows that contain 
that search string are displayed.

Now, what I'd like to do is to customize the ItemRenderers so that the portion 
of text in any ItemRenderer that matches the search string is displayed in a 
different color and underlined.  

I know I've seen a demo of this somewhere?  Any ideas?  Or, any ideas how to 
implement?

My idea is to make a custom DataGridItemRenderer and set it at the DataGrid 
level so each of the columns will use it.  And then on the data property, loop 
through each of the items being displayed and then format accordingly.  
However, this seems inefficient, especially since I've already implemented some 
filterFunctions on the dataProvider...

Thanks for any suggestions.

Nope. I can bolt in zip/unzip and a JSON encoder/decoder - but not AMF.

Speaing of which, I think I've asked my question badly enough that no
one thought to suggest JSON. I guess my most general question is:

"What techniques can I explore for reducing message sizes that work
efficiently in Flex?"

As I understand it:
-- AMF is native & fast.
-- JSON is not native & I'm not sure how fast it is.
-- XML is native and relatively fast...for XML.
-- Unzipping is native and fast...but not many methods are supported.
-- Custom binary protocols are fine as long as I draw the data down
into a general object or ByteArray and then parse it myself. Of
course, that means the parser is running in ActionScript - not code
compiled into the player.

Any other ideas?

[flexcoders] New with Flex: Problem with data binding

[Martin Gorostegui]

Hi people, 

I'm starting with Flex technology and have some doubts on how datadinding 
between client-side objects work.
After reading Adobe's Flex3 and playing with some samples I ended up with the 
following situation:
Created a Product.as class declared as bindable.
Created a product.mxml in which I declare the following:
...

...

...

For what I understand the first binding is to make sure that the product's name 
is set to what the user entered in the textControl and the second binding can 
be used to load an initial value in the textControl from an existing product. 
right?

Now, my Product class actually has a Dimensions(width, height, etc) attribute, 
where Dimensions is another as class created by me and declared bindable.

How can I bind, for example the width of my Product to another textControl?
Can I nest a Dimensions tag inside the Product tag?
or add to the Product tag an attribute like 
dimensions.width="{widthControl.text}"?

I'd also like to achieve the same binding by creating the Product instance in 
actionScript and not using mxml tags. Is this possible?

Any example on how to do these will be aprreciated as I tried different ways 
but couln't get what I want. Any example on the web or open source project that 
I can use as a guide for this case? (trying to create a 
list-create-modify-delete screen and want to reuse the Product form for 
creation and modification) because I found Adobe's examples on this theme to be 
too simplistic.

Thanks in advanced,

Martin

If anyone can comfirm the same issues are happening to them in SDK 3.3 and FP 
10, that would be great.

thanks!

Hi there,

I've run into an issue that I am sure others have, but I cannot find a
solution. I am using cairngorm with a webservice. I need to send in my
soap body the less than and greater than characters. In my mxml based on
user input, I use <>. I follow the call and flex converts the
<> to <> until the AsyncToken gets a hold of it. It should convert
it back to <> for the soap call, however it takes the first & and
converts that too.. so the outgoing soap looks like this "<> "
instead of "<>".

Anyone know why this is happening or a solution?

Thanks in advance

[flexcoders] LCDS Upgrade Problems

Document is a Flex thing.

I don't recall the scoping rules in Flash, but it may be that the variable is 
not public or not declared on myFlash.  You might also try waiting for frame

RE: [flexcoders] Module unload GC

[Alex Harui]

Modules will unload when there are no longer any references to the classes or 
objects in a module.  There is a cache, but it uses weak references and will 
release the module when using the gc button in the profiler.  The browser 
caches module SWFs but that won't affect this issue.  Nate's solution sounded 
like the solution to the problem where you update a module on the server and 
want to load the new one.

If a module brings in a component that hasn't been loaded before, usually it 
brings in a CSSStyleDeclaration for it as well which gets registered with the 
central StyleManager and pins the module.  You can check the id in the id 
column to see if the module that is pinned is the first one loaded.

Subject: Re: [flexcoders] Module unload GC

Garbage Collection happens when it needs to happen.  You have no control over 
it.  This is from Grant Skinner's blog:

Deferred GC and Indeterminacy
A *very* important thing to understand about the Garbage Collector in FP9 is 
that it's operations are deferred. Your objects will not be removed immediately 
when all active references are deleted, instead they will be removed at some 
indeterminate time in the future (from a developer standpoint). The GC uses a 
set of heuristics that look at RAM allocation and the size of the memory stack 
(among other things) to determine when to run. As a developer, you must accept 
that fact that you will have no way of knowing when (or even if) your inactive 
objects will get deallocated. You must also be aware that inactive objects will 
continue to execute indefinitely (until the GC deallocates it), so code will 
keep running (ex. enterFrames) , sounds will keep playing, loads will keep 
happening, events will keep firing, etc.

It's very important to remember that you have no control over when your objects 
will be deallocated, so you must make them as inert as possible when you are 
finished with them. Strategies to manage this will be the focus for a future 
article.

Garbage Collection happens when it needs to happen.  You have no control over 
it.  This is from Grant Skinner's blog:


Deferred GC and Indeterminacy
A
*very* important thing to understand about the Garbage Collector in FP9
is that it's operations are deferred. Your objects will not be removed
immediately when all active references are deleted, instead they will
be removed at some indeterminate time in the future (from a developer
standpoint). The GC uses a set of heuristics
that look at RAM allocation and the size of the memory stack (among
other things) to determine when to run. As a developer, you must accept
that fact that you will have no way of knowing when (or even if) your
inactive objects will get deallocated. You must also be aware that
inactive objects will continue to execute indefinitely (until the GC 
deallocates it), so code will keep running (ex. enterFrames) , sounds
will keep playing, loads will keep happening, events will keep firing,
etc. 
It's very important to remember that you have no control over when
your objects will be deallocated, so you must make them as inert as
possible when you are finished with them. Strategies to manage this
will be the focus for a future article.

RE: [flexcoders] help with httpService Error

[Ryan Graham]

It's probably something to do with policy file changes in FP9 and 10.
Here's some links that explain the changes that may be of help:

 

http://www.adobe.com/devnet/flashplayer/articles/fplayer9_security.html

 

http://www.adobe.com/devnet/articles/crossdomain_policy_file_spec.html

 

You may want to start troubleshooting with an open crossdomain.xml and
start tightening up from there:

Hi, 

 

I am using FlexBuilder 3.0.2 and am getting a new error on new projects
when using the httpService feature.  Here is my httpService control, as
copied from an older project which still works:

 

https://www.someserver.edu/myfiles/flexfile.php";
useProxy="false"

  fault="show_fault(event.fault)">

  

  getmetainformation

When I run the app locally, ctrl+f11 or clicking the run button in
eclipse, I get the following error:

 

[RPC Fault faultString="Security error accessing url"
faultCode="Channel.Security.Error" faultDetail="Destination:
DefaultHTTP"]

 

If I copy the swf file up to the server, it does run correctly there.

 

That exact same httpService control works fine in a project I finished
last fall when run locally.

 

The weird thing is that older projects, ones I did as little as a month
ago, run just fine when run locally.  It's only the new one I started
this week.

 

I tried adding  to
my crossdomain.xml file, but no go.  I am using Flash version 10,0,22,87
within Firefox 3.05 on windows Vista, fully patched.  

 

The only thing that I can think that would have changed from a few

Re: [flexcoders] Module unload GC

[Nate Beck]

Well if we're talking about modules...

If you're loading the same module over and over again that might be the
problem... A while back I had to modify ModuleLoader and while I was in the
code I seem to remember it has some caching built into it.  So it may be
possible that ModuleLoader is holding on to a reference of a module.

I got around the caching issue when loading the same module over and over
again by appending a random number to the loaded module.  (ex:
myModule.swf?uid=123456789).

The ModuleLoader stuff I was working on was back in 2.0.1... so it might be
very different now.

Hope this helps.

[flexcoders] Problem in Sorting XMLListCollection (which is dataProvider for) the List

[anuj181]

Hi Guys 
I am trying to sort the dataProvider in the list which is in the form of 
XMLListCollection, I am using amfPHP for grabbing data in the form of 
XMLListCollection and for the display purpose I am using labelfunction to 
display just the friendly name of my entries which is the specific attribute 
from the XMLListCollection. I went through few tutorials online for sorting and 
came up with the following code but some how this is not working, Can any one 
please help me in figruing out whats going on here and why sorting of the list 
is not working,
Thanks


/**CODE*/
  




[Bindable] private var entriesXmlListFull:XMLList;
[Bindable] private var entriesXmlCollection:XMLListCollection;


public function getListHandler(event:ResultEvent):void
{   

entriesXmlListFull = XML(event.result).device;
populateEntries();
}
private function getListFault(event:FaultEvent):void
{
Alert.Show("Error retreiving Data");
}

//Displaying names need to be displayed in the List box
private function entriesLabelFunc(item:Object):String
{
var xmlItem:XML = item as XML;

return xmlItem..attribute.(@name=="friendlyname");
}

//Populating List with XML Objects
private function populateEntries():void

RE: [flexcoders] HTTPService vs URLRequest

[Jeff Vroom]

Of course HTTPService uses URLLoader when you are using a direct connection to 
your server.   HTTPService supports resultFormats, data binding, proxying with 
blazeDS, channel set failover, MXML tag definition, and AsyncToken's for more 
flexible code notification.   URLLoader is well covered in the flash 
documentation but there's no reason you can't use it for Flex too.

[flexcoders] Passing reference to a custom class

[Deane Venske]

Ok I'm not sure that this is possible BUT:

I have written a class to simplify our data transfers for my developers, 
but what I wanted to achieve was a single line call to the class that 
would do everything:
var dlAccounts:DataLoader = new DataLoader("php/index.php", vars, 
model.xmlAccounts, true, pbrLoadProgress);

That model.xmlAccounts variable is actually the variable I want to end 
up having the data in it. What I've seen though is that once it's passed 
to the class the reference to it is broken, so any data put into the 
class variable that holds it does not end up in model.xmlAccounts. I 
know that I SHOULD create an event that gets run when the data is 
loaded, which I've done and it works great there, but I was hoping to 
accomplish this all with 1 single call considering nothing really needs 
to happen after the load is completed everything from there works on 
bindings.

I guess one idea is that I could potentially declare model.xmlAccounts 
as my class instead of an XML object, which would mean that class 
handles everything for that variable. Anyone wanna scream at me for 
doing something that silly? :P

Thanks,
Deane

I'll get one for DMV too, though you can search the bugbase yourself.

Hi there,

I've run into an issue that I am sure others have, but I cannot find a
solution. I am using cairngorm with a webservice. I need to send in my
soap body the less than and greater than characters. In my mxml based on
user input, I use <>. I follow the call and flex converts the
<> to <> until the AsyncToken gets a hold of it. It should convert
it back to <> for the soap call, however it takes the first & and
converts that too.. so the outgoing soap looks like this "<>"
instead of "<>".

Anyone know why this is happening or a solution?

Thanks in advance

RE: [flexcoders] Preventing HSlider from moving forward

[Ryan Graham]

How are your users interacting with the slider? Be sure to cover all
interactions - i.e. clicking on the track to move the slider, dragging
the thumb, etc.

 

You can listen for the change, thumbPress, thumbRelease, and thumbDrag
events and provide your functionality there. In the thumbDrag handler
you could check the value against the one you are limiting the position
to, and kill the event there.

[flexcoders] [Tree][move scrollbar to selectedIndex] how to ?

[fotis.chatzinikos]

Hello everybody,
after much search on programatically opening a tree node, openItems, 
selectedIndex, and calllater magic, I managed to open AND select a node deep 
inside an mx:tree.

The problem? this node might be lower in the tree than is visible (scrollbars 
appear as needed).

Any ideas how to move the scrollbar where the selected node is?

TIA,
Fotis

[flexcoders] AsyncToken with special chars

[thibodeau.alain]

Hi there,

I've run into an issue that I am sure others have, but I cannot find a 
solution. I am using cairngorm with a webservice. I need to send in my soap 
body the less than and greater than characters. In my mxml based on user input, 
I use <>. I follow the call and flex converts the <> to <> until 
the AsyncToken gets a hold of it. It should convert it back to <> for the 
soap call, however it takes the first & and converts that too.. so the outgoing 
soap looks like this "<>" instead of "<>".

Anyone know why this is happening or a solution?

Thanks in advance

Re: [flexcoders] How do you populate a DTO from view components?

[Jeffry Houser]

 You can get 2-way binding in MXML using the mx:binding tag.  I'm not 
sure if that would be cleaner / better than your current approach, though.

[flexcoders] How do you populate a DTO from view components?

[Rodrigo Pereira Fraga]

Hi, 

I'm looking for a better solution for it. 
I have two solutions:

1- With a model declared with a DTO(MXML)



2- With custom components, like it:


But I'm not happy. Does anybody has an another solution?
The problem is that the [Bindable] doesn't have a bind bi-direcional, like

[flexcoders] Re: Web service, parameters, errors... Help please

[Jim]

Tracy,

> The value you want to pass needs to be in the text node, not in an
> attribute.  Something like:
> 
> X

The above line won't work; it gets the error message about 
"Initializer for 'Find__CompIntfc__DL_TREE_IB_CI'; values of type 
com.draper.Find__CompIntfc__DL_TREE_IB_CITypeShape cannot be represented as 
text." with or without quotes.

I wonder if you would be willing to help me flesh out the function path (As I 
said, I'm pretty new to this, both Flex and ActionScript).

private function betterway (): void
{
var myService:GetInfo = new GetInfo();(is that right for myService?)  
var sValue:String = "something";
var oRequest:Object ={ Find__CompIntfc__DL_TREE_IB_CI : sValue };

 myService.send();

If I try this, I get an error that there is no send() method for GetInfo.  If I 
switch it to 
 myService.findID(oRequest)
I get an error that type Object is being coerced to "possibly unrelated type 
com.draper:Find__CompIntfc__DL_TREE_IB_CITypeShape."

Thanks for any light you can shed.

[flexcoders] HTTPService vs URLRequest

[Osman Ullah]

Surprisingly, I am having a very difficult time finding any discussion on the 
advantages of using HTTPService instead of URLRequest. I've always used 
URLRequest to handle my web API calls. What are some of the benefits of using 
the HTTPService instead? I like URLLoader because my network libraries aren't 
dependant on flex, but I don't quite understand why Adobe makes very little 
mention of URLLoader in their Flex documentation, and also doesn't have any 
articles comparing HTTPService to URLLoader.

[flexcoders] Cannot upload files using Filereference /PHP returns

[William Paulton]

I am trying to create a very simple flex/Air app that can load content such as 
small jpg or text file from a local directory to a content server (ISP using 
Apache) using the file refernce Class. I am using a simple php script to handle 
the server side processing, and which is referenced in the url of the 
URLRequest object.

However when ran  an IOErrorEvent is fired generated with the code #2038 - 
stream error. 

Inspection of responserHeaders provided by the the 
StatusEvent.HTTP_RESPONSE_STATUS object returns a http status code of 403 (403 
Forbidden)and the message "You don't have permission to access 
/MyCMS/uploader.php on this server". 

I have tested the php script and server directory paths which appears to be 
correct. 

Do you have any ideas?

[flexcoders] Re: Images

[app.developer]

You have the three images you mentioned earlier, let's name them imgLogoLeft, 
imgCenter, imgLogoRight.

Take an HBox, (imagine a table in HTML that has 3 columns) placing the 
imgLogoLeft first, a Spacer to "push" the logo images apart from one another, 
and imgLogoRight.

With each logo image, you may wish to set the attribute "scaleContent" to false 
so the image doesn't scale to the size of the  container.

The  container's background is set to your small 1 pixel image and 
then set the backgroundSize attribute to 100% to stretch it to the size of the 
HBox.

[flexcoders] adobe TV - QR code reader

[Kenneth Sutherland]

I'm trying to track down an episode describing how to create a QR code
reader with a web cam (the little square barcodes).  I know I've watched
a video tutorial on this in adobe TV, but I can't find it.  Tried
multiple searches in Adobe TV and using Google but nothing.

Has anyone got a link to the tutorial.

Cheers.

Re: [flexcoders] try, catch, finally ...

[Alan K]

This sounds like the try-catch is not being used as ( how I see ) intended.
As Alex mentioned, they are costly so unless you need it, skip it.

I suggest just adding an IOErrorEvent listener/handler to the caller, and
if/when the call is complete then remove the listener(s) for GC. In the
Œtry, catch¹ scenario,  your code is always Œchecking¹ for the error.

I would use a sort function, so I could debug any problems.

 

I'd also suggest an e4x expression instead of the loop.

Re: [flexcoders] Using sessions in flex

[Jeffry Houser]

Flex doesn't have the concept of pages the same way that an HTML 
application does. 

Store your session state as part of the Flex App (AKA in the client).  
And you can hide/unhide sections of the app based on the login 
credentials.

Hi All,
Iam getting some issues in Flex. I have two pages in my project one is 
for non-admin and another for admin users.
A link will be shown for non-admin users and not for admin users. 
While the user is logging in, if the username and password are wrong 
then it will automatically redirected to non-admin page and a link is 
showing up there. This is the actual scenario.


This working fine when we are executing admin or non-admin at a single 
time. If in Mozilla if i first execute non-admin page in the first tab 
so a link will come for me. And in the other tab i am executing admin 
page. Now the link will not be shown in admin page. So its not showing 
any link in the admin page but its also not showing in non-admin page 
also. Non-admin page is affecting by admin page data.


Admin and non-admin pages are identified based on Admin flag coming 
from the database. For admin page admin flag is 1 and non-admin page 
admin flag is 0. If admin flag is 0 only that link ll be shown. So at 
the first time if the user execute non-admin page admin flag is 0 and 
link ll be shown. If the user execute admin page admin flag is 1 and 
link ll not be shown. So the admin flag is changing to 1 and the link 
is also not showing in non-admin page also..


So here the problem is how can i save the admin flag value according 
to the session. Are we able to use sessions in Flex so that i can save 
the admin flag in the session and i access it based on the session id.


Hope u got my problem!! Plzzz help me if anyone faced this issue before..

Thanks in Advance,
poornima

Re: [flexcoders] Images

[Fotis Chatzinikos]

To set an explicit height or width for an imported image, set its height and
width properties of the
Imagecontrol.
Setting the
height or width property prevents the parent from resizing it. The
scaleContent property has a default value of true, therefore, Flex scales
the image as it resizes it to fit the specified height and width. The aspect
ratio is maintained by default, so the image may not completely fill the
designated space. Set the scaleContent property to false to disable scaling.
Set the maintainAspectRatio property to false to allow an image to fill all
available space regardless of its dimensions. For more information about
image aspect ratios, see Maintaining aspect ratio when
sizing
.

Maybe try maintainAspectRatio = false? or explicitly set its width to what
you want...

[flexcoders] URLStream readObject error 2006 when trying to read larger amounts of data

[eak0703]

I was wondering if anyone could help me fill in some of the details about how 
URLStreamer works.

Here's what im trying to do: I have a Java back end server that establishes a 
long lived connection to my Flex front end. I am using URLStreamer to do this. 
I am then serializing Java objects into AMF and sending these down to the Flex 
client.

Once the data gets to the Flex client I am getting a progressEvent. I then use 
the readObject method if there are bytes available to be read.

This works absolutely fine from "small" objects, but when I try to send down 
any object with some actual data in it (probably more than 65535 bytes) i get 
this "Error:#2006 Range Error". Also I get array index out of bounds. Both of 
these I get on the actual: urlStreamer.readObject() call!

My theory is that my message is actually too big and is being split among 
several different firings of the progressEvent.

Here's where I need help: 
Is my theory correct? 
If so, how am I supposed to know when I should actually be trying to 
"readObject()"?
If readObject() is supposed to "read the object from the stream"...shouldn't it 
handle these larger objects for me? IE: shouldnt urlStreamer "buffer" the 
partial data for me...and only let me "readObject" when there's a complete 
object to be read? or should I be "buffering" the binary that comes in...trying 
to read object each time there are "bytesAvailable" and if there are 
errorsjust swallow them and wait for more bytes?

Any help would be appreciated. I've searched these forums, but it seems like no 
one has been running into things like this. 

Thanks in advance

RE: [flexcoders] Web service, parameters, errors... Help please

[Tracy Spratt]

The value you want to pass needs to be in the text node, not in an
attribute.  Something like:

X



 

Also, this declarative syntax is hard to debug.  I suggest invoking your
call in an as function:

var sValue:String = "X":

var oRequest:Object ={ Find__CompIntfc__DL_TREE_IB_CI : sValue };

myService.send(oRequest);

Subject: [flexcoders] Web service, parameters, errors... Help please

 

I'm new to Flex and web services. I've created a web service in PeopleSoft
and successfully imported the WSDL into Flex so that it has contacted the PS
server and returned data (using mx:WebService and mx:Operation code I found
examples of). However, I have been unable to pass a parameter to the service
from Flex using that code. I then discovered and followed the sample code in
the Flex-generated package, but no matter what I do I cannot successfully
supply the "myValue" in the sample shown below. Here is Flex's own text in
my GetInfo.as file built by Flex:

* MXML sample code:
* First you need to map the package where the files were generated to a
namespace, usually on the  tag, like this:
xmlns:ws="com.draper.*"
* Define the service and within its tags set the request wrapper for the
desired operation
* 
* 
* 
* 
* Then call the operation for which you have set the request wrapper value
above, like this:
* 

My code is:





When I try to run it, Flex is unhappy with the value I am assigning ("X"
above) no matter what I put there. If I omit the double quotes and try to
assign a text input field value (which is my goal here), it complains that
it expects a double quote. If I put almost anything else there, it complains
either:

Initializer for 'Find__CompIntfc__DL_TREE_IB_CI'; values of type
com.draper.Find__CompIntfc__DL_TREE_IB_CITypeShape cannot be represented as
text.

or, if I try this line, where I attempt to pass a text input field:



then I get:

1067: Implicit coercion of a value of type String to an unrelated type
com.draper:Find__CompIntfc__DL_TREE_IB_CITypeShape

Can anyone help with this please?

Thanks

Re: [flexcoders] Newbie : Video Capture and Streaming Questions

[p...@vin Uttarwar]

Hi,

Yes you need Streaming server like FMS or Red 5 to use NetStream.connect()
method.
Netconnection Creates a bidirectional connection between a Flash Player or
AIR application and a Flash Media Server application.
