[flexcoders] Upload Image
Hello, What is the instruction to use for uploading an image ? And how to use this image in the flex application when uploaded ? Thank you, Christophe
Re: [flexcoders] Upload Image
In order to upload the image, you will need to handle the binary data sent from your Flex app on the server via some server side language (ie. ColdFusion, PHP, Java, etc...). All Flex does, is facilitates the transfer of the data from the client's computer via rpc/web service/http service etc... Have a look in the Flex docs for the File classes used to select the image within your app. Brendan On Fri, Mar 6, 2009 at 2:06 AM, christophe_jacquelin christophe_jacque...@yahoo.fr wrote: Hello, What is the instruction to use for uploading an image ?

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.

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

[flexcoders] Re: Upload Image
You may wish to manipulate the image before you upload to the server. With Flash 10 drawing API, you may upload to the client application, manipulate the image, then save the image by uploading the image to the server. A good article is Senocular's tutorial, Flash Player 10 Drawing API http://www.senocular.com/flash/tutorials/flash10drawingapi/ . Also suggested is to change a few settings in your Flex Builder or Eclipse with Flex plug-in. Work with Flex SDK 3.2 or higher and for that particular project, in the project properties to compile in the lower selection, Require Flash Player version: 10.x.xx. I have mine set at 10.0.22 at the moment. You will also need the Flash Player so go to http://www.adobe.com/support/flashplayer/downloads.html .

Re: [flexcoders] Merapi and execute file from AIR
I need to start the AIR app and execute files and programs from another language that is able to do that. I'm actually using java, which is working very well (with Merapi). This app will be deploy on Windows, Mac and Linux. So java is, in my opinion, the best candidate to have a cross-platform deployment (well at least I know how to do it with java and it is working well).

[flexcoders] AIR SQLite:Does anyone have this issue with DB connected asynchronously?
Hi all, Before I present the issue, I am listing my FB and SDK versions: - FlexBuilder 3.0.2 - AIR SDK 1.5 - Flex SDK 3.3 milestone build. All the latest good stuffs. Now, I have an issue with DB that's connected asynchronously doesn't ALWAYS firing SQLEvent.RESULT or SQLErrorEVENT.ERROR whenever a SQL statement is executed. For example: I got a login screen with login textInput, password textInput, and login button. When the login button is clicked, it does a query to check whether the login and password exist in the DB. And events will be fired accordingly if it's a success or not. HOWEVER, the events don't always fired! Sometimes it fires but sometimes it's not. It's happening intermittently. Does anyone else have this issue?? Btw, I don't have this issue at all when I have my DB opened synchronously. Unfortunately, working with it has some big challenges as well. So if I can get the DB-async to work properly, it will save a lot of time. Thx!
[flexcoders] colorPicker panel height

I have a panel that only has 9 swatches in it in one row. Each swatch is 22
x 22 pixels, but the panel is 100 pixels tall, i.e. ~4x taller than it need
to be. The other ~75 pixels are blank space.
The documented list of attributres for swatchPanelStyleName doesn't seem to
cover panel height (see below, from docs).
Is that list exhaustive?

[flexcoders] Re: Lazy loading in AdvancedDataGrid using RemoteObject
wow Amy,
Some of your articles helped me a lot, realy thanks you:)
Now I looked at your example and using AdvacedDataModel with RmoteObject,
getting the data from my Java code, couldnt rally see how can I use it
(although I would love to), if you can guide me with the adaptations, please
do...
I actaualy used your advice regards the AsyncToken, and I have some results, I
get the data from the server, but I have lots of problem controlling the expand
of the desired branch, when I click the branch, the data is fetched using the
RemoteObject but childrens expand and collapse immidiatly :(
My code:
in my mxml:
1. I load first the data for the dataprovider to show only parents
2. When we click on the closed parentId we activate:
private function onItemOpen(event:AdvancedDataGridEvent ) : void
{
var remoteService:RemoteObject=getDataFromHandler();
// getLazyData is the func from my server to get the data
var news:AsyncToken = remoteService.getLazyData
(event.item.GroupLabel);
news.addResponder(new mx.rpc.Responder(setAttributes, onFault));
}
public function getDataFromHandler(): RemoteObject {
dataService = new RemoteObject(MyHandler1);
dataService.showBusyCursor = true;
dataService.destination=DataGridRemote;
return dataService;
}
The RemoteObject goes to the server and when its back it activates:
protected function setAttributes(event: ResultEvent): void {
var dm:DataModel;
// my object from the server
dm = DataModel(event.result); model =
MatrixDataModel(dm.model.getItemAt(0));
// my function that converts my Object to DataProvider
remoteDP = createProvider(model); //
Create Headers
createHeaders();
// create upper group columns
setGroupedColumns();
}
It sims that the correct data is on the grid but after a split sec it collapse.
WHY???
Can i use your code to make all better?
Thanks a lot for all your help, really

Hi guys,
I am strugeling to figure out lazy loading in my AdvancedDataGrid.
I didnt find any relevant document on that.
If I'm using ItemRenderer for my columns to do manipulation on the data, it
is executed when I click on the grouped (branch )column.
This is good if I ahve a dataprovider with all data.
But if I want lazy loading,
When or where should I create my RemoteObject to fetch the relevant data
from the server?
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.
Can I do it in my ItemRenderer?
Other option, If I catch a click from my AdvancedDataGrid and figure out
the parentId, and fetch the relevant data from the server, how can I
activate the Itemrenderer that I need to manipulate with this new data?
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.
Many questions regard this Lazy loading, can you guide me here please?
You might find this example helpful:

[flexcoders] [slightly OT] RSS pull?
Excuse me in advance since it may be OT. I am putting together a small RSS reader using Flex. I'd like my application to look like automatically updating if there is any new post coming in for the RSS feed that the user is currently viewing, etc.. What I can think of on the top of my head is using HTTPService in my Flex piece to constantly pull the RSS feed and check against the lastBuildDate value to decide if the data have changed. I wonder if there are any open-source (or free, which means the same to me anyhows;)) server side solutions that can push the data? Or is there any smarter way of doing this purely on the client side? Thanks and have a great Friday!

RE: [flexcoders] Re: Timers and local CPU
That was going to be my suggestion. The main thing that makes an itemRendrer heavy or expensive is basing it on a container, like VBox, instead of on UIComponent.. Yours looks good. And I think maybe I would store the start time and calculate the elapsed time, rather than incrementing the elapsed time on each timer tick. It might be a little more accurate, and would let you adjust the timer interval. You might find that 2 or 3 seconds is a short enough interval, and would lower the cpu load quite a bit.

RE: [flexcoders] Refresh DateField
For a date, the timer interval could be long,, like a minute or more. That
wouldn't be much overhead.
If you have any other timers running, you could piggyback that functionality

[flexcoders] curly braces and functions in mxml
Is there a difference between
mx:Button click=onClick()/
and
mx:Button click={onClick()}/
The only thing I've notice is in the latter I can CTRL+Click on
onClick and it takes me to the onClick function, while the first one
does nothing
[flexcoders] Re: curly braces and functions in mxml
Both in this case do the same thing. Curly braces tell Flex that it should
treat the contents as ActionScript (thus you can Ctrl-click it). It's basically
a function call. Take a look here for an explanation:
http://www.onflex.org/ted/2005/06/property-binding-in-flex.php
In the case of your code, the click property of the Button component converts
the string it receives to a function call automatically; it's redundant to use
the curly braces but it shouldn't hurt anything.

[flexcoders] Re: curly braces and functions in mxml
Hi Rick,
Both will work, but you don't need the binding (curly) braces for events
(click). This is a common mistake; one that I've made myself. In
essence, when you use the curly braces to bind, you are creating an
event listener; usually to a variable. When the variable changes
(except for arrays), the binding mechanism will automatically update any
properties that are bound to the variable. This works great for
properties and styles, but is un-necessary for events. Simply by using
an event in an mxml tag, you are already doing the same thing; creating
an event listener. When the event is dispatched, do something; done.
Sometimes binding is confused with just referencing properties and
methods.

[flexcoders] save word file to database.

RE: [flexcoders] Re: hiding an applicationcontrolbar button
Yes, the content of the toggleButtonBar will be determined entirely by its
dataProvider. If you want to change the content of the button
Bar, you must change its dataprovider.
One way to do this is to add/remove the viewstack children.
But this process has always seemed unnecessarily difficult, just to change
the visibility/availability or a button, so I never use a viewStack as a
dataProvider for anything that needs to be dynamically controlled.
Instead, I use a separate dataProvider, for the control bar, which contains
the index into the viewStack, and manipulate that dataProvider to control
the available buttons. A click on a button uses the index in the
dataProvider to set the selectedIndex of the ViewStack.

[flexcoders] Re: HorizontalList ItemRnderers Mysterious Horizontal Gap
Alex, I tried this. I also tried putting the Image control inside of an HBox, and still no dice. I got closer, but still could not entirely get rid of the gap. There was always at least 1px on a side that was still coming through. I have actually resorted to creating my own component, which is a sub-class of the Box container. It takes a dataProvider, a max count, and an itemRenderer and builds out the UI. For some reason this approach is giving me the control I want over the details of the UI.

[flexcoders] Flex Builder 3 on Windows XP
I have a weird problem. My PC crashed yesterday and after re-booting Flex builder would not start. When clicking on the icon, you get the initial Flex screen but then it disappeared and nothing happens. After struggling for a couple of hours, I decided to uninstall and reinstall Flex. Now when I run the installer, InstallAnyWhere gets to about 43% and stalls, then jumps to 99% and then asks for another location to extract the installer. When you specify a different location, the same thing happens all over again. This is the same installation file I used before, so I know it is not corrupt. Also, when I checked my registry, there is not entry for Flex under Adobe in HKEY_LOCAL_MACHINE -- Software. Any help is appreciated. Thanks!

[flexcoders] Re: save word file to database.
It can be a pain reading/writing binary data regardless if what server side code you use. I'd advise against it unless you need to hide the Word docs from someone coming along and accessing them directly. If you use a good authentication/authorization mechanism to protect the web app, you shouldn't have to store them on the database. You could use some simple code in your server-side app to give the files a new name while writing them to a folder. And you'd store the filename/location to the database as a string (varchar). Then other apps could also access the files if necessary. - Alex C --- In flexcoders@yahoogroups.com, Jeffry Houser j...@... wrote: Although possible to save binary docs in a database, I recommend against it.

There are definitely times this would be well worth considering, but right now I'm focusing on what can be done without the extra layer of software. I'm well-enough versed in the specifics of this back-end that what I've been trying to sort out is what is native and reasonable in the Flash player. It's on the client side that I'm ignorant. As in so many other areas of my life;-) But, pertinent to this list, I'm ignorant about many aspects of the Flash player and the Flex framework - the framework is huge and many features are easy to overlook. So far it looks like (ignoring back-end): * AMF - Native * XML - Native * JSON - Often used library * Plain-text format - May be able to leverage native features such as String.split() or a custom parser that reads lengths precisely. * Any of the textual formats (XML, JSON, plain-text of whatever sort) may benefit from compression, depending on payload size, compression/decompression time, and network conditions (latency and bandwidth). That's what I've got so far.

I think (some) people were asking about the back-end to try to help you configure http compression, which is done differently with different servers. Given your requirements, that and XML is probably the way to go for the short term, although simple hand-rolled textual formats may offer much better performance with negligible complexity for some stuff. -Maciek -Original Message- From: David Adams dpad...@gmail.com Reply-To: flexcoders@yahoogroups.com To: flexcoders@yahoogroups.com Subject: Re: [flexcoders] Re: Compressing messages/data: What binary/compression formats are workable in Flex?

You don't change the content-type to reflect gzip compression being on on the server. Gzip is a content-encoding and the browser should seamlessly decode it.

[flexcoders] blazeds mapping issue with SetLong
Hi,
I am having some problems with blazeds and how it maps a collection contains
long elements.
Let's assume I have a class
public class MyClass {
..
private SetLong myLongs;
public void setMyLongs(SetLong myLongs){
this.myLongs = myLongs;
}
public SetLong getMyLongs(){
return myLongs;
}
}
and I have a mapped class in flex and a instance of this class containing an
arraycollection with for example [1, 4]
Now I'm sending this instance to my remoteobject
..
public void receiveStuff(MyClass m){
}
The problem I'm having now, is that blazeds actually mapped the 1 and 4 not as
a Long into myLongs but as a Integer.
Sofar this is not a big issue, but I'm passing it forward to hibernate and
there it leads to some errors:
org.hibernate.type.LongType - could not bind value ... to parameter: ...
java.lang.Integer cannot be cast to java.lang.Long
I found already some bug reports on that in
https://bugs.adobe.com/jira/browse/BLZ-79 but it's marked as resolve with the
solution don't use java syntax 1.5 which is not very helpful. So if someone
has a solution/workarround/idea please let me know.

I am strugeling to figure out lazy loading in my AdvancedDataGrid.
I didnt find any relevant document on that.
If I'm using ItemRenderer for my columns to do manipulation on the data,
it is executed when I click on the grouped (branch )column.
This is good if I ahve a dataprovider with all data.
But if I want lazy loading,
When or where should I create my RemoteObject to fetch the relevant data
from the server?
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.
Can I do it in my ItemRenderer?
Other option, If I catch a click from my AdvancedDataGrid and figure out
the parentId, and fetch the relevant data from the server, how can I
activate the Itemrenderer that I need to manipulate with this new data?
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.
Many questions regard this Lazy loading, can you guide me here please?

[flexcoders] Basic question: Creating, tracking, and deleting objects.
I've been experimenting with a couple of classes that extend Canvas
and realize I need to get some basic information sorted out. I've done
quite a bit of googling, looking through examples, and checking
Adobe's documentation. Somehow I've lost the plot. Briefly, my
questions are:
* How do people normally track references to dynamically created objects?
* If you add an object to an array, are you copying a reference or
something bigger in RAM?
* How do you well and truly clear an object?
References to a good, basic demo would be most welcome, too.
Those are the questions, below is the background that leads to the
questionswhich may be skipped if the questions alone make sense.
What I've got is a class I've called SearchGroup that extends Canvas.
This is just a bounding container that is meant to coordinate a number
of child containers of calls SearchRow, which also extends Canvas. So,
there is one SearchGroup with 1 or more SearchRow instances. I'm going
everything in ActionScript rather than MXML as I'm trying to get
comfortable with AS.
When a SearchRow is created, it should go at the bottom of the
SearchGroup canvas (visually).
When a SearchRow is deleted, any rows below it should be moved up.
That's about all I'm trying to do at the moment and there are probably
better built-in widgets to use. My main problem is sorting out how you
properly create, track, and delete objects. My main application has an
initApp() like so:
public function initApp() : void {
this.addChild(searchArea.addRow());
this.addChild(searchArea.addRow());
this.addChild(searchArea.addRow());
}
Whenever addRow() is called, a row is created, added to the display
list, and some private variables are updated within searchArea (a
SearchGroup):
public function addRow() : SearchRow {
_rowCount ++;
var row:SearchRow = new SearchRow(_rowCount);
_rowReferences.push(row);
return row;
}
[I figure that SearchRow shold be an inner class of SearchGroup - but
I don't know how to do that in AS. Otherwise, I assume I should put
addRow into SearchRow and then have SearchRow dispatch an
event...which I'm skipping for the moment for simplicity.)
So, when a row is added, the searchArea increments a count and appends
the reference into a private array named _rowReferences. A couple of
questions:
* How do people normally track dynamically created object references?
* When I copy an object into my array, _rowReferences.push(row), am I
copying a _reference_ or something more substantial in RAM?
When I come to delete a row, I'd like four things to happen:
* Decrement the row count - that's easy.
* Remove the reference from the tracking array - that's easy.
* Remove the item from the display list - that's easy, assuming I get
the right parent reference.
* Remove (delete/clear) the row object instance. How do you do that?
I've not found a remove/delete/clear option or operator that appears
to do anything. I'm fuzzy on the AS/Flex garbage collection system, I
expect.
Thanks again for any help! Eventually I'll be able to contribute
answers instead of questions to the list.

Nobody has attempted this?

However, if I set a variable inside an Application.cfm file, it doesn't get recognized inside the cfc functions when called through LCDS Destinations. I've confirmed that the application.cfm file is getting called, and my application scope variables are getting set. I've also confirmed that the application.cfm file is getting initialized before the lcds data call to the cfc. However, once the CFC gets run, it errors out saying that XXX is undefined in Application. I've changed the scope parameter inside my Destination definitions in data-management-config.xml to be application instead of request but this didn't help either.
