[flexcoders] Thanks Alex!
I have no idea who is still listening to this thread but I think it's time to humbly, and gratefully thank Alex for his devotion to Flex and this thread. Two years ago our world was shaken and we've all moved onto different (not better) things. ;) Alex has continued to demonstrate and keep his promise in supporting Flex two years down the road and will probably continue to monitor these and other threads for several more. Hats off to you Alex! You are to commended for your devotion and sacrifices to our beloved Flex! James LongLiveFlex/

Re: [flexcoders] Flex and AIR on Mobile Platforms

Flash is now in decline as a plugin technology. It will continue for a good few years yet, but it is trending downwards. Because its life as a plugin is drawing to an end, Adobe is seeking to reshape Flash as an app-building tool. This makes perfect sense, and if they do it well, they could manage to make an army of Flash/flex developers into app developers, which is not all bad. Adobe has read the writing on the wall and is putting a lot of effort into re-shaping themselves as the tool provider for HTML5. Certainly there is a need for great tools in this area, so I hope they succeed in doing this. Also, you might note with interest their purchase of nitobi, who make PhoneGap.

I've seen some mixed messages - Adobe's version which is just a change in focus while the industry reads it like a Flash obituary. Here are two bullets from Adobe's announcement: --from Adobe.com •Shifting resources to support even greater investment in HTML5, through tools like Adobe® Dreamweaver, Adobe Edge and PhoneGap, recently added through the acquisition of Nitobi •Focusing Flash resources on delivering the most advanced PC web experiences, including gaming and premium video, as well as mobile apps -- I can almost see them sitting around the board room table debating whether to stick that , as well as mobile apps on the end of bullet 2 just to leave people like us (Flex developers I mean) confused. Pretend you're a Samsung or Motorola executive planning the next release of your latest mobile device. Do we spend $10 million and 40 developers integrating Flash? Since the vast majority of new, innovative applications involve incorporation or embracing of mobile clients, Flash's ubiquity, which is/was its greatest selling point, is gone. I mean when Jobs took a stand to ban Flash from iOS - that was a phaser blast to the holodeck, but this...this is a photon torpedo to the bridge. Am I reading this wrong, or should I be starting my new HTML5 career now? I mean once flash is gone from mobile, it is gone as a general web application framework so forget those desktop focused applications too, except some specialized graphics oriented apps. I think of what I'm developing now on Flex and it would be years away from possible with HTML5 but maybe I should be focusing on HTML5 plus one of the better JavaScript frameworks? I'm really looking for some opinions here about what flex developers think of the near term future based on this announcement.

Re: [flexcoders] Could AIR create an automation app?
Not direct invocation but you can control them through NativeProcess that can pass a command of argument and received standard output from the application like Command Prompt. That right, AIR is made to be as portable as possible. For your case, you can use .Net or C# to automate those task. For easier coding, consider AutoIT which is widely use by System Admin to automate routine tasks, you can do a simple control like mouse and window position to advance control like hook DLL. I did used AutoIT in the past. On Mon, Aug 8, 2011 at 12:07 PM, MicC chigwel...@yahoo.com wrote: ** Does AIR have enough hooks to the os to create an automation app?

[flexcoders] SocketMonitor and XMLSocket
Using Flex 4.5 and AIR 2.7.
It seem to be buggy for 2 situations,
I declare a timer for the socket
private var socketTimer:Timer = new Timer(500,1);
Code 1:
This code took a few seconds before executing NativeProcess
public function onTimerComplete(event:TimerEvent):void {
socketMonitor = new SocketMonitor('127.0.0.1',8090);
socketMonitor.addEventListener(StatusEvent.STATUS, socketStatusChange);
socketMonitor.start();
}
private function socketStatusChange(e:StatusEvent):void {
if(socketMonitor.available==false xSo_start==false) {
xSo_start=true;
xSoDump(); //Execute NativeProcess EXE
}
}
Code 2 (Optimize):
This code will execute NativeProcess immediately but after a few mins,
NativeProcess will hang by itself without any error:
public function onTimerComplete(event:TimerEvent):void {
socketMonitor = new SocketMonitor('127.0.0.1',8090);
socketMonitor.addEventListener(StatusEvent.STATUS, socketStatusChange);
socketMonitor.start();
xSoDump();
}
private function socketStatusChange(e:StatusEvent):void {
}
Code 3 (Optimize):
This solve the hanging issue when I place xSoDump on the 2nd line.
public function onTimerComplete(event:TimerEvent):void {
xSoDump();
socketMonitor = new SocketMonitor('127.0.0.1',8090);
socketMonitor.addEventListener(StatusEvent.STATUS, socketStatusChange);
socketMonitor.start();
}
private function socketStatusChange(e:StatusEvent):void {
}
SoDump will execute a nativeprocess (Sodump.exe) which will setup a server
connection of 127.0.0.1:8090. So the server will interactive with XMLSocket.
Is SocketMonitor have any connection with XMLSocket?
In certain situation, NativeProcess will hang itself too, this lead me to
wonder if anyone encounter the same issue?
In code 2, I'm sure SocketMonitor has time out and close the XMLSocket
connection after it fail on the first try?

unique as it auto-increments), categoryid, label, icon and url. I then have a
table called userlinks containing the values userid (NOT primary and NOT unique
as this table is intended not to have a primary key), linkid, categoryid,
label, icon, url and favourited (default value for favourited is 'N'). When the
user creates a new account it creates a new userid for that new account in my
users table. '$param_userid' is what I've assigned this value to in my php code
as the logged in user. What I want is for each time a user creates an account a
copy of all of the records in all of the columns in the links table is copied
into the corresponding columns in the userlinks table as well as the values of
$param_userid (the logged in userid) and favourited ('N') being applied for
each record. Can anyone help me out with the code for this? I'm very
inexperienced at using php.
I also then want a query which when a user logs in with an existing account all
of the data from the links table is copied over in the same way except this
time it overwrites any records which the user with the logged in userid has,
based on linkid and also inserts any new records which may have been added to
the links table that they haven't had since they created their account (again
with the logged in user id '$param_userid' and 'N' for favourited values added
for each record).
I hope this makes sense and I'd be very grateful if anyone could help me with
these 2 queries.
[flexcoders] SetItemAt Not Updating Tilelist Icons Correctly
My app allows users to enter in a url a title and an image filename and then
when they click a button a snapshot of this url is created and sent to the
server as the filename they have entered and an item containing all this data
is added to an array collection which displays all this within a tilelist, the
item renderer is linked to the server which contains the images (via the i) so
they are displayed within the tilelist. The thing is this I'm trying to allow
my users to update these things using the setitemat method i.e. they click on
an item and all it's data is displayed and they can edit it and then save it
which will use the setitemat function to update this item in the array
collection.
My problem is this, if the user changes the url it takes a snapshot of this new
url to overwrite the previous image on the server but if they keep the image
filename the same it doesn't seem to refresh within the tilelist itself. I know
the image on the server has been overwritten as the image on the server in
question has been changed when I check it but for some reason the image in the
tilelist isn't updating to the new image. It's as if flex has the old image
stored in memory or something and won't switch to the new one. Is this common
and is there anyway around this besides refreshing the whole array collection
each time the user updates an item. Is there any way of refreshing only the
item that has just been updated perhaps? The strange thing is if the user
enters a different image filename.
Here's the line of code which updates the selected item (with 'a' being the
chosen item in the tilelist):-
ArrayCollection(linkChoice.dataProvider).setItemAt({linkid:linkChoice.selectedIt
em.linkid, categoryid:updatedcategoryid, label:updatedlabelentry.text,
icon:updatediconentry.text, url:updatedurlentry.text}, a);

This may sound simple but I'm having trouble implementing the code. I have a combox box in my app (categorySelectorDropdown) populated by an array collection which contains the property 'categoryid'.

Can anyone advise me on what the sysntax should be?
[flexcoders] How to find the Value of a Property in the Last Object of An Array Collection
I want to allow my users to add their own values to my array collection
'linksFullAC' using the following code which gets fired when they click a
button:-
linksFullAC.addItem({linkid:?, label:userenteredlabel.text})
Except I want the link id value to autoincrement so that each time they add an
item it is the value of the highest linkid in the array collection +1. For
example if the highest linkid in the array collection is 53 and the user clicks
this button the new link would be assigned a value of 54 for the linkid. Can
anyone please help me out on the code I'd use to do this?
[flexcoders] Re: Changing a combobox's SelectedIndex upon A Button Click
Thanks. I'll take a look. I found another solution:-
for each(var currentCategory:Category in _categories) {
if(currentCategory.id == chosencategoryid) {
categorySelectorDropdown.selectedItem = currentCategory;
break;
}
}
Cheers for your help.

[flexcoders] Need Help Getting A Value Into My App Via Flex And Php
I know this may not be the place to ask about php but I thought people may have came across a similar problem. Basically the data for my app is stored in a mysql database table and what I need to do is get the auto increment value of this table into my app via a http request. I'm trying to make a php file which gets this value and outputs this value as xml but I am awful at creating php to do such things and just get constant errors. Can anyone take a look at this and help me out to tweak it so it does what I want please? The table in question is called links and the field/row/column in the table I'm after is called linkid. It's the next autoincrement value of that row outputted as xml is what I want. Here's the php so far:- ?php header(Content-type: text/xml); $host = ; $user = ; $pass = ; $database = ; $linkID = mysql_connect($host, $user, $pass) or die(Could not connect to host.); mysql_select_db($database, $linkID) or die(Could not find database.); $tablename = links; $next_increment = 0; $qShowStatus= SHOW TABLE STATUS LIKE '$tablename'; $qShowStatusResult = mysql_query($qShowStatus) or die ( Query failed: . mysql_error() . br/ . $qShowStatus ); $row = mysql_fetch_assoc($qShowStatusResult); $next_increment = $row['Auto_increment']; echo next increment number: [$next_increment]; ?

have
only one size. You should make multiple sizes and place them in the
images folder. You should also set the width and height inside the
custom component depending on the size you want (I have them hard
coded
in my example). Then you would pass a size to the custom component
by
exposing a public variable and use a switch statement to select the
correct size.

Hi Steve. As I said earlier about using e4x I'm reluctant to use amfphp 1. because I already have eveything set up using regular php code and 2. I. struggle to find examples of how to use such methods compared to the regular methods of using traditional php. Would you happen to know if it is possible to send a copy of the array collection that I'm receiving somehow? I basically want it so that when the user logs in it gets the data that we've been discussing throughout this topic and sets it as an array collection in flex and then sends this whole array to the userlinks table I have in my mysql so each user basically has a whole copy of the links table to themselves and can edit this by setting favourites etc. How would you go about this judging by the code that I've got here (the code that Robert provided). I'd prefer to stick to php to upload the array as this project is for my uni course in which I've used php throughout but I suppose I could use amfphp to upload the arrays?

An empty result will have created a zero length array and you can trap on that. I use WebORB for PHP (Community Edition which is free) as the PHP middleware and have never had a problem.

That does sound like essentially what I'm after yes but the problem is I'm not

creating custom components :'-( Plus I think the answer may be within an edited
tilelist component now.
What I've managed to get so far (from another site) is a custom component based
on a tilelist with my item renderer added into it. It has the blue themed
rollover and selection squares completely removed for both rollover and
selection but what I need to do is edit this code to instead do what I've
described i.e. selection itself produces no visual effects but whilst an item
is hovered over it's image converts to colour and it's image and label glows
and when it is unhovered over the image returns to greyscale and all glow
effects stop. Can you help me with this by any chance or point out what I would
have to do to this code to achieve my own such component that allows the visual
effects I need? I have some glow/unglow effects aswell as converttogreyscale
and converttocolor effects from previous apps :-) Here's the code I've got for

A...Why do you say repeater items can't be selected?
I built a custom component that responds to a mouse click and then repeat
this component multiple times using a repeater from data that is returned
from my server (Essentially this is a list of regions containing customers.
Each user is only authorized to see specific regions/customers so the number
of custom components repeated is set from this data).
The custom component is fully self contained and responds to mouse clicks. If
the underlying application needs to know about the clicks, I dispatch a
bubbling event which the app listens for.
So, in your case create a custom component with your different skins
(greyscal/colored). The component should contain multiple sizes of images as
well as a public var to set the size. The app should know the stage size as
well as the number of items to display (From the server call). In your
repeater, set the public var to the size you need. Each custom component can
have its own overskin etc and respond appropriately as well as its own event
listener for mouse clicks.

[flexcoders] Re: What is the Correct Type of Component For This?
Thanks so much for helping me out valdhor. I've been racking my brains trying
to find it. I've even been trying to draw circles which glow inside the
drawselectionindicator of my tilelist component but that would look a bit bland
and is a pain to position them.
In that code you found there are 2 very interesting lines of code mainly those
which relate to the image inside of his item renderer abd the code which they
are pointing to for their glow effect:-
mx:Image id=myImage source={data.image} width=100 height=100
alpha=0.6
rollOutEffect={outerDocument.myOut} rollOverEffect={outerDocument.myOver}/
And this:-
mx:Parallel id=myOver
mx:Blur blurXFrom=30 blurYFrom=30 /
mx:Fade alphaFrom=0.6 alphaTo=1 /
mx:Resize widthTo=150 heightTo=150 easingFunction=Back.easeOut/
mx:Glow alphaTo=20 blurYTo=20 blurXTo=20 color=0x00ff00 /
/mx:Parallel
I'm assuming that if I can incorporate my effects into that code then I'll be
able to do the same. At least I hope. But what exactly does outerdocument mean?
I've came across it but never used it and I also have what a parallel is but if
it works I could care less :-)
Thanks for being so helpful. I'll let you know how it goes here.

images folder. You should also set the width and height inside the
custom component depending on the size you want (I have them hard coded
in my example). Then you would pass a size to the custom component by
exposing a public variable and use a switch statement to select the
correct size.

[flexcoders] Re: What is the Correct Type of Component For This?
Valdhor I've implemented the code from the last example you gave me and
visually I have it working perfectly now, converting to color/grayscale,
glowing/unglowing everything. I only have one problem with it which is I'm
totally unsure as to how to get it to simulate the selecteditem click in the
app itsef. You see previously I used a combobox as my category navigation/links
filterer which had the index 0 set as the default selected item and as the user
clicked each combobox item it filtered the links data within my links tilelist.
How can I implement the selected item property into the repeater so that as the
user clicks on each item it is set as the selected item the way it would be in
a combobox/tilelist?
You see the problem is I have a filter function which gets applied to my links
tilelist array collection dataprovider which was previously (when I used the
combobox) set to:-
if(category.categoryid ==
categorySelectorDropdown.selectedItem.categoryid) {
return true;
}
else{
return false;
}
}
So as you can see without being able to have a selected item property I can't
use this filter function effectively :-( Sorry to be a pain but it's just that
I remember you mentioned you used a repeater which simulated a tilelist
selecteditem click and I was wondering how this could be done with my code so
the repeater we have acted in this way?

Basically what I mean is I previously had a combo box populated by an array

an array collection that also contained the property category id. So therefore
when a user selected an item in the tilelist only the items that had a
categoryid which matched the category id of that selected item were shown

[flexcoders] What is the best Way - Multiple DataProvider's or one?
In my app I have a tilelist with an array collection as it's dp which is populated via remote xml from a mysql database. When a user clicks a certain category button in my app it sends a request to the server to tell it which category items the user wants to see which in turn changes the array collection that populates the tilelist so it shows items within that category. The thing is though this seems to be a bit unreliable as it means the user has to wait for a while for the dataprovider to change so sometimes they click to the next category and the items from the previous category are still shown in the tilelist. Is it better practice to have multiple dataproviders initialsed at startup which the user can switch between as they click each category rather than modifying the same dataprovider? Basically I'm just wondering what way would you guys do it? I thought using just one dataprovider would slim down the code and make the app faster and more reliable but now I'm not sure.
[flexcoders] Re: Problems With my XML Created Array Collection
Thanks Tracy that looks good. I may try something similar in the future. I've
managed to get the previous example provided by robert working though so
basically I'm thinking if it isn't broke don't fix it. :-) It's all that I
require really as I'm only using it to display the results and it covers
everything I need. Thanks a lot for your advice.
While you're hear would you happen to know how to upload an entire array
collection to a server via php/http request? You see the thing is at the moment
I have an app which allows users to create links and remove links which
directly creates/removes them in the mysql database I have which holds my data.
To explain what I want basically I have a links table which contains all the
available links and a userlinks table in my mysql database. When the user
creates a new account via my app all the links from the links table are
displayed in the app using the method we've been discussing but now I want the
user to be able to add the entire contents of this to the userlinks table. The
purpose of this is the user can favorite each link which will alter a boolean
field in the userlinks table which will mean in turn when a user logs in with
an existing account the links they've favourited will be displayed.
So basically firstly I need to know how to add/send mulitple records via
flex/php. I have no problem adding/removing and updating individual records but
I now need to know how to add multiple ones at once. Is there any way of doing
this and do you know of any similar examples?

I know this is very late in the game, and I havenât read the full thread,
but this seems like a very complicated solution to the problem. Further, the
default resultFormat has other consequences, data type conversions for
example. If you have a string that looks like a number, it will get
converted to a number, removing trailing and leading zeros and such, and
sometimes this is not desired.
Using e4x and looping over the categories.category XMLList is very simple.
XMLLists are never null, but empty nodes just result in a zero length, which
is easy to test for.

Hi Amy. Sorry I missed your post yesterday. e4x does seem good but I was just a little bit worried about implementing it.

Small change, but you should get in the habit as LinksService.lastResult will cause some pain in the future if you decide to change it's name for some reason. Amy suggested using e4x which is probably the correct answer as e4x grants you consistency ( you do not have the arrayCollection returned sometimes and ObjectProxy others) and allows you to work with XML in actionscript like XML was meant to be accessed. You will still have to trap for the same issues, just implemented in a different way. We do not always use e4x although we probably should, being lazy will probably bite us one of these days. I think you've misunderstood. By changing the result format from the default of object to e4x, you _avoid_ the problem the OP had, which is if there is only one object returned, you get a different result than if you have multiple objects returned. You don't have to trap for the problem, because it goes away. If there is only one node, you get one node. If there are multiple nodes, you get multiple nodes. But whatever. -Amy
[flexcoders] Re: What is the best Way - Multiple DataProvider's or one?
Hi I would but my code is pretty big. To sum it all up basically I have an application which displays links in a tilelist based on whatever category button the user clicks on. Each time the user clicks a category it sends the categoryid (which I've made as a variable that changes based on whatever category icon is clicked) to the server which gets all the the links that have that specific category id and displays them in the remote xml file which poulates the array collection that acts as the dataprovider for the tilelist. What I may do, which seems to be a better solution, is rather than constantly sending requests to the server instead simply get ALL the links from the table and also make the categories in my app dynamic and apply a filter function within my application that depends upon what category is clicked which will mean that the data will be getting handled within the app rather than getting passed back and forth. I think this is the best solution. The app also allows user to create and remove links so I suppse the only time I'll have to resend data to refresh the array collection to include such alterations is after the user adds, removes or updates data. --- In flexcoders@yahoogroups.com, sminrana sminr...@... wrote: Can you show your code? --- In flexcoders@yahoogroups.com, Tracy Spratt tracy@ wrote: As usual, it depends.

The thing is my xml is retrieved from a mysql database table which sometimes

nodes which in turn causes the problem whereas sometimes it has many records
therefore the xml file would have many nodes which would mean no problems.
I've heard of looping but can't figure out how to do it or apply it to my code.
I've tried simply changing the array collection to xmllist collection but then
the data doesn't seem to appear in my tilelist.
How would you loop using my specific code there because I always need it
returned as an array collection to populate the tilelist but have no idea how
to loop?
Cheers for your help so far.

ArrayCollection to populate value objects that we were using to populate our

[flexcoders] Re: Problems With my XML Created Array Collection
Hi Robert. Thanks so much for that my friend.
I have some problems with it though. You see I have an event in my app applied
to a button (refresh button) which resends data via the LinksService i.e.
LinksService.send and I've noticed that with your code if there is only 1 link
i.e. 1 node and I click the refresh button it seems to keep recreating that 1
over and over again as if it's recreating the same object in the array
collection or something. This doesn't happen if their are 2 or more

Another question though what if the xml contains no nodes?
You see my xml file is dynamic, I have a variable in my app called categoryid
and that variable is based on a category that the user selects in my app and is
submitted to getlinks.php which gets all the records from my mysql table which
contain that specific submitted categoryid and output them as the xml file.
Some categoryids have no records (the user can add and delte records via my
app). Is there any way of getting it to handle 0 records/nodes as well as
handling muliple records/1record which it seems to already do?
Thanks so much for your help. Sorry to be a pain :-(

Subject: [flexcoders] Re: Problems With my XML Created Array Collection
The thing is my xml is retrieved from a mysql database table which sometimes
will have no records or 1 record which will mean the xml will have only 1 or
no nodes which in turn causes the problem whereas sometimes it has many
records therefore the xml file would have many nodes which would mean no
problems.
I've heard of looping but can't figure out how to do it or apply it to my
code. I've tried simply changing the array collection to xmllist collection
but then the data doesn't seem to appear in my tilelist.
How would you loop using my specific code there because I always need it
returned as an array collection to populate the tilelist but have no idea how
to loop?
Cheers for your help so far.

We had the same issue, and in our case it was an easy fix. When we read in
the XML it was returning as an ArrayCollection as long as there were
multiple nodes. As you have found, if it was only one node it returned as
a generic object not an ArrayCollection. We were already looping through
the ArrayCollection to populate value objects that we were using to
populate our list. So before the loop we added, if xmlObject is an
ArrayCollection than loop else populate VO with returned data. Worked
without issues ever since.

[flexcoders] Re: Problems With my XML Created Array Collection
You were right about removeall (flush ha whoops) helping. I applied removeall
before the if statements like you said and the first error is now gone.
The only problem I have now is the error which occurs when there are NO nodes
in the xml i.e. all items have been removed and there are no values in my mysql
table which relate to that specific category id.
I've changed the code to this:-
private function linksResultHandler(event:ResultEvent):void
{
LinksFullAC.removeAll();
if(LinksService.lastResult.categories.category is ArrayCollection) {
LinksFullAC=LinksService.lastResult.categories.category as
ArrayCollection;
}else if (LinksService.lastResult.categories.category is ObjectProxy)
{
var oCat:Object = new Object();
oCat.linkid =
LinksService.lastResult.categories.category.linkid;
oCat.categoryid =
LinksService.lastResult.categories.category.categoryid;
oCat.label = LinksService.lastResult.categories.category.label;
oCat.icon = LinksService.lastResult.categories.category.icon;
oCat.link = LinksService.lastResult.categories.category.link;
LinksFullAC.addItem(oCat);
}
}
The thing is though in that code I have the first if statement to check for if
the result is an array collection which sets it as an array collection, the
second if statement which if it is an object proxy adds the single object to
the array collection but I think what I'll need is a third if statement which
checks if the xml is empty/null or something and assign what will happen if it
is null. Do you know of any way to do this and if so what do you think is best
to set as the operation of such an if statement to make sure this error doesn't
occur anymore? I thought it might be something like:-
if(LinksService.lastResult.categories.category is null)
but there seems to be no such thing. Any ideas?
Sorry to keep hassling but it's pretty much the last hiccup I've got in my app
and I always try to pick the brains of guys who know their stuff as much as I
can :-)

[flexcoders] Re: Uploading An Image Without Browse
Cheers Jeff. I'm sure that'd work too. I've found a way around it and can now
allow users to upload without the browse. The problem is though I now want it
to upload the file without it having to save it on the user's machine first. At
the moment my code snapshots the html component, saves this as a bitmapdata,
resizes this bitmapdata, then a jpegencoder turns this bitmapdata into a jpg
file which is named after whatever the user has entered into a text input
component in my app. It then uploads this jpeg from the location it's saved to.
I'm wondering is there any way of me editing my code so it uploads the jpeg
straight away rather than storing it on the machine too? Here's my script code
containing the function which does all this:-
mx:Script
![CDATA[
import mx.graphics.codec.JPEGEncoder;
import mx.graphics.ImageSnapshot;
private var imageuploadurlRequest:URLRequest;
private var serverSideScript:String = *my upload php file goes
here*;
private function imageuploadinit():void {
imageuploadurlRequest = new
URLRequest(serverSideScript);
}
private function takeSnapshot(event:Event) :void{
var bigbmd:BitmapData =
ImageSnapshot.captureBitmapData(linkviewer) ;
var scale:Number = 0.50;
var matrix:Matrix = new Matrix();
matrix.scale(scale, scale);
var smallbmd:BitmapData = new BitmapData(bigbmd.width *
scale, bigbmd.height * scale, true, 0x00);
smallbmd.draw(bigbmd, matrix, null, null, null, true);
var jpgEncoder:JPEGEncoder = new JPEGEncoder( 100 );
var ba:ByteArray = jpgEncoder.encode(smallbmd);
var enteredimagename:String = titleentry.text;
var file:File =
File.applicationDirectory.resolvePath(('assets/createdimages/')+enteredimagename+('.jpg'));
var wr:File = new File(file.nativePath);
var stream:FileStream = new FileStream();
stream.open( wr, FileMode.WRITE);
stream.writeBytes ( ba, 0, ba.length );
stream.close();

[flexcoders] Allowing Jpgs saved Within Flex to be named by the user
My app allows a user to take a snapshot of a website and it then saves this

jpg BEFORE it is saved eg if they type in yahooimage into a textinput component
in my app (imagenameentry) and then click a button to create the image it will
be automatically saved as yahooimage.jpg.
At the moment I've just got the file saving as userimage.jpg but I tried
editing a bit of my code which creates the file to this:-
var file:File =
File.applicationDirectory.resolvePath('assets/images/'imagenameentry.text'.jpg');
This never worked and throws a syntax error but if I use:-
var file:File =
File.applicationDirectory.resolvePath('assets/images/userimage.jpg');
Then it saves but as I say I want the image to be nameable like in the top
example so that whatever the user enters in the imagenameentry box will be set
as the name of the image. What am I doing wrong here and is there another way
to do this?
[flexcoders] Uploading a Specific file rather than browsing
My app allows users to create a user-named jpg like so:-
var enteredimagename:String = imagenameentry.text;
var file:File =
File.applicationDirectory.resolvePath(('assets/images/')+enteredimagename+('.jpg'));
However I now want to allow a user to upload that specfic file automatically to
my server by clicking a button which will simply upload that file WITHOUT
having them browse for it. So basically I need it set up so that when the user
clicks a button whatever name they type into the imagenameentry.text will be
the image that gets uploaded. For example they create an image which they name
yahooimage by typing yahooimage into the imagenameentry text input component.
Once a button is clicked this will save this image as
assets/images/yahooimage.jpg but I want to advance this button click further so
that this specific jpg is then set as the file for upload without browsing for
it. All the examples I've seen use the browse function though which is not what
I want.
How can this be combined with the filereference method or some other way so
that the file to be uploaded can be entered into a textinput component as
described above rather than browsed for?

I'm now looking for good examples of using Facebook connect to do the following:- - View a user's statuses - View all a users albums and photos - Allow a user to post a new status to Facebook - All a user to upload a new photo to a specific album What I really want is to be able to do all of the above WITHOUT the user being taken to the 'Allow Access' window of Facebook which opens up in a new instance of Explorer, the reason for this being that I want my app to be entirely self contained or if there is no way around this I'd like to have it so the allow access window opens up in a html component within my application. Is this possible would you know? --- In flexcoders@yahoogroups.com, valdhor valdhorli...@... wrote: What did you manage to glean from the Twitter API documentation? --- In flexcoders@yahoogroups.com, James garymoorcroft_ict@ wrote: I am looking for the quickest and simplest possible method to allow a user to post a tweet to twitter from within an air application.

[flexcoders] Best Way To Tweet To Twitter From an Air Application
I am looking for the quickest and simplest possible method to allow a user to post a tweet to twitter from within an air application. Basically I just want them to be able to enter their name and password in my app type what they want to tweet and click a button and it will tweet it to their profile.

[flexcoders] Idea For An Application - Universal Social Network Accesor - Is this possible?
In my air app I have a twitter feed in which all of a users tweets will be displayed if they eneter their twitter name and click load. I want to expand on this so that I can also get data from facebook and perhaps Bebo and MySpace by including feeds from them also to display things like users pictures etc. Obviously twitter is easy as it basically involves no pictures and is merely a list of posts for each user. The thing is I've noticed in the case of facebook you need to go into Facebook and click allow access etc to allow your own api key to access your details on your profile. What I want is so that users can enter their facebook username and password in my app and their facebook details such as photos will be displayed within my app. The thing is there will be multiple users of this application. Is this possible and can anyone recommend any good tutorials on getting such things to work?
[flexcoders] Dynamic Shared Object - Is This Possible?
What I want in my app is to have 2 tilelists and an array collection of items which will populate the first tilelist and these objects can be dragged between both tilelists. Then the user can click a save button which will save the statuses of both tilelists so the items that are present/not present in each tilelist when the app is closed will still be there when the app is restarted. The problem is I want my array collection to be populated dynamically from mysql data on a server. I have no problem getting dynamic data from a mysql database into an array colllection via http request and I have no problem getting the shared object to work IF the array collection is defined within the app the usual way but I'm having trouble getting these 2 things to work together. Can anybody tell me if it is indeed possible to have a dynamically populated array collection stored as a shared object on the user's system and would anyone be willing to help me out if I post my code so far? Cheers.

You'll have to explicitly handle the case where your user comes back and has
sets
a: [3,6,8]
b: [1,2,4]
but items 8 and 2 are no longer on the server, but it should be easy enough
to
loop over the SharedObject once the data has been fetched and shuffle the
item to the right list if it exists.

[flexcoders] Using An Array Collection Produced From XML In Conjunction With Shared Object
I have an old app which allows the user to drag items between two tilelists and
then save the contents of both tilelists by clicking a save button using the
sharedObject method. The tilelists are populated by array collections defined
in the app. I want to change this so that the tilelists are instead populated
by an array collection which I've retrieved from a remote xml file via http

[flexcoders] Using Server Stored Images In An Air Application?

[flexcoders] Having Trouble With Filtering Tilelist's/DataProviders
I've done some research on this and I think I'm getting there but I can't seem
to get it working in my own app. I have two tilelists categoriesTilelist and
productsTilelist populated by two array collections categoriesAC and productsAC
which are populated from remote xml files.
One of the attributes in both xml files/array collections is categoryid. What I
want is when a user clicks an item in the categories tilelist for only the
items within the products tilelist which have the same categoryid value of that
particular item to be displayed.
I know I need to use a filter function for this but it doesnt seem to work.
I've made a filter function called filterFun and then made a function which
should set this filter which I've applied as the item click property of the
categoriesTilelist. Here's the code I've got for these:-
if(product.categoryid ==
categoriesTilelist.selectedItem.category.categoryid) {
return true;
}
else{
return false;
}
}
public function setFilterFun():void{
productsAC.filterFunction = filterFun;
}
That doesn't seem to do anything when I click the categories after I run the
app. Can any of you guys tell me where I'm going wrong?

[flexcoders] Writing images to the src folder in flex/air
In my app I have a jpegencoder which saves bitmap snapshots of components as jpgs in my images folder (assets/images). The problem is it saves them in the bin-debug folder rather than the src folder. The reason I want them in the src folder is so that I can embed them within the app and it seems you can't embed images that are in the bin-debug folder. The reason I want to be able to save them directly into the src/assets/images folder is so that they will replace current images I have stored there which are embedded within the app so hopefully as they are saved these will replace the images live within the app if that makes sense. The current line of code I have which saves the images in the bin-debug folder is this:- var file:File = File.applicationDirectory.resolvePath(assets/images/testpicture.jpg); Can anyone tell me how to modify this so that they save in the source/src folder rather than the bin-debug folder? Thanks.
[flexcoders] Getting A File To Save In a Location So It Overwrites Currently Embedded Jpegs
I'm using air for this and so far I can make bitmaps and convert them into jpegs from within my app and place them on the desktop using the following code:- var file:File = File.desktopDirectory.resolvePath(abcnews_small.jpg); This creates the abcnews_small.jpg file on the desktop and overwrites it if it already exists there. However what I want is for my app to overwrite jpgs that I've already embedded IN the app but I'm struggling to figure out how to do this. My jpgs are all stored in the src folder under assets/images/ so for example my project is called liveimage and the location in which my abcnews_small jpg is located is liveimage/src/assets/images/abcnews_small.jpg and it's embeddded in the app like this:- [Bindable] [Embed(source=assets/images/abcnews_small.png)] public var abcnewspicture:Class; So if I can set up the following line of code so that it saves the new jpg in the above location that'd be perfect. I've tried the following but it doesn't work:- var file:File = File.applicationStorageDirectory.resolvePath(abcnews_small.jpg); If anyone can help me out on this I'd be grateful. Thanks.
[flexcoders] Using 'setitemat ' to make images within a tilelist dynamic
In my app I have a tilelist which gets it's data and images from a data
provider 'myTileListAArrayCollection'. I have a function which takes a snapshot
of a component and saves it as a bitmap. What I want is for this bitmap to be
saved so that it overwrites an image jpg I have defined in a class
'abcnewspicture'. Obviously this will mean that the tilelist will have default
images but then once the snapshot is taken and replaces the jpg the image
within the tilelist will change dynamically. Here's the code which sets the
object of the array collection in question after the snapshot has been taken.
myTilelistAArrayCollection.setItemAt({id:yrhe, label:reyery,
icon:abcnewspicture}, 0);
Can anyone help me out on saving this bitmap as a jpg so that it overwrites an
existing jpg in my assets/images folder of the app? I've searched and can't
find a solution for this anywhere.
[flexcoders] Binding the Souce of an Image to the Icon Property of an Array Collection
Is it possible to do this as I can't seem to get it working? For example the

as the myImage source changes. I've tried this but it doesn't work:-
{id:First Item, label:First Item, icon:{myImage.source}},
Can anyone help me out on this? Thanks for any suggestions.
[flexcoders] Making The Icon property of An Array Collection Dynamic Through Data Binding
In my app I have an image component (myImage) which originally has no source
and a hmtl component (myhtml) and a tilelist component (myTilelist). Basically
when the site is fully loaded into the html component a function I've made
takes a snapshot of the html component and sets this snapshot as the source of
the image component effectively making it a thumbnail snapshot of the website.
What I want is when this happens for the same image to be applied to the 'icon'
property of the array collection which acts as the dataprovider for my tilelist
component. So when the source of the image component changes so does the source
of the icon property in the array collection i.e. whatever is displayed in the
myImage component is also displayed in the icon property of the 'First Item' of
the array collection meaning whatever changes are made to the image are also
made to this icon. I tried this but it doesn't seem to work:-
{id:First Item, label:First Website, icon:{myImage.source}},
What code would I need to add in or put in the icon property to get this to
work?
[flexcoders] Twitter Feed Within An Air/Flex Application
I've previously made an air application for my university course and my tutor has suggested that I incorporate more live data into it. One of the ways he suggested was to include a twitter feed. I have no experience of using feeds within flex but I think I've managed to get one in. How it works is when users type in their twitter id and click a load button all of their tweets are displayed within a repeater component. They can then click a save button to save their twitter id and whenever they start the application in the future their tweets will load into the repeater component automatically as long as their name has been saved. This may seem like silly question but does what I've described constitute a 'live twitter feed' which is what I've been asked to include or am I missing something?
[flexcoders] Need Help With an App Which Produces Live Images
At the moment I have an application which is meant to produce live thumbnail
images of websites. Currently how it does this is a html component (myhtml)
loads websites via it's location property changing from website to website and
upon fully loading of each site a snapshot is taken of the html component and
saved as a bitmap and applied as the source of an image corresponding to that
particular site (abcnewsimage and bbcnewsimage). However I now need to insert
these snapshots within the 'icon' properties of 2 array collections
(myTilelistAArrayCollection and myTilelistBArrayCollection) which act as
dataproviders to populate 2 tilelists (mtTilelistA and myTilelistB).
Basically I need the same images to appear automatically within the tilelists
the way they do in the 2 images as the snapshots are taken by applying the same
bitmaps into the currently empty 'icon' properties of the 2 tilelists i.e. the
icon of the ABC News Item of both array collections must be the same as the
abcnewsimage and appear as it appears and the same for the BBC News Item icon
being the same as the bbcnewsimage picture as that appears.
It should look like the images aare appearing in the tilelist at the same time
as they are appearing in the regular images. What will I need to ut into the
icon properties to do this?
I hope this makes sense and if anyone can help me out it would be much
appreciated. :-)

[flexcoders] Re: Twitter Feed Within An Air/Flex Application
But is it possible within flex to have a feed that acts live such as this i.e. it is constantly changing? I thought within flex you could only load data upon some sort of event such as the click of a button? The user can refresh their tweets simply by clicking the load tweets button again but may it be better to have a refresh function constantly running and refreshing the feed every couple of seconds to keep it essentially 'live'? I thought something like this would take up memory/loading times though. The ability to post tweets to twitter from within an app does sound like a great idea though. I wouldn't know where to start on this though. Do you know of any examples on the net that show this being done that I could implement into my own? Cheers for your help though. These are good ideas. --- In flexcoders@yahoogroups.com, turbo_vb timh...@... wrote: Hi James, If your application automatically displays new tweets, those created after the initial load, than yes; that would be considered live.
