[flexcoders] Searching through an ArrayCollection of Objects
Hi, I was wondering if there are any quick ways to solving this, quick as in CPU time, not developer time... I have an Array Collection of VO's called contact which has two properties... var myAC : ArrayCollection = new ArrayCollection(); var myContact : Contact = new Contact(); myContact.name = bob; myContact.age = 30; myAC.addItem(myContact); var myContact : Contact = new Contact(); // Also, Is this bad practice? Am I loosing the reference to previous myContatc? I'm sure someone mentioned this to me once on this list? myContact.name = bill; myContact.age = 31; myAC.addItem(myContact); var myContact : Contact = new Contact(); myContact.name = sarah; myContact.age = 28; myAC.addItem(myContact); I now want to write a function which takes the ArrayCollection to scan, the name property value of the object and it will return the age property of the first found VO. At the moment, I'm just looping through the collection without sorting them and it all seems to work. I've had a look at the Array API and have found sortOn and lastIndexOf(), etc but am thinking is there a time benefit in sorting first and then looping or is there a super function that does exactly what I want and super efficient? I was thinking is it worth converting to XML then using E4X queries but the conversion is probably time comsuming. In reality myAC will be about 300 elements so maybe a brute force looping scan might be good enough but having started this, I'd like to hear what you others think. Thanks in advance, Nick

[flexcoders] bind ColorMatrixFilter to php (Apply ActionScript graphic manipulation to php)
Hello, I am working on an online photo manipulation project. Users load images, modify them, and save modifications. Later, a high quality version of the image is printed. Due to specification constraints, the printing process must be performed by php. I've been looking, without success, for a way to bind actionscript modifications with php. For instance, the user applies some saturation modifications to an image, and saves them. Since we want non-destructive image editing, the modifications are saved in a database(actually, the corresponding ColorMatrixFilter values). Later, when the user loads his images again, the modifications are loaded and reapplied to the image. When launching the print job, thousands of high quality processed image must be handled, in php. So, my question is : can anyone point me in some direction on how to make a bridge between these ColorMatrixFilter values to a graphic process, writen in php (using GD or anything else for example) ? In my idea, the php script would load the modifications from the table, maybe use a convert script, and then apply the filters to the high def image, before printing. Thank you for your time, and possible answers. Sorry for my english.

Re[flexcoders] strict user input in TextInput
Hi all. How would I achieve the task of restricting user input based on the current contents of the TextInput? I am aware of the restrictChars property but that doesn't help since it applies a blanket rule as to which characters are allowed/not allowed. An example here would be: allow the user to input a number with no more than a precision of 2. In this case, as soon as the user enters 12.34 any more keystrokes in the TextInput should become no-ops. I did try adding event listeners to the KeyboardEvent.UP_KEY and KeyboardEvent.DOWN_KEY but it seems that you can't stop the propagation or prevent the default of keyboard events. Any suggestions here would be very much appreciated.

I'd be surprised if this compiles, since the CollapsiblePanel tag contains a
reference to a function, handleCreationComplete(), which does not appear in
your (malformed) Script tag. Does that function contain anything that
populates listItems (which I don't see a declaration for)? If not, maybe you
should try binding to _queryVariables, which is the only ListCollectionView I
see getting populated here.

[flexcoders] Dynamically create a Value Object...
The program that I'm working on is for a company that does registrations for conventions and trade-shows. Different clients want different information stored for each show. Most of the information is the same from show-to-show, but every show has certain customizations that need to be done. The way they're doing it now is by going into the source code of their program and modifying it that way. We could do the same thing with our Flex app, but I'm trying like heck to avoid that... The problem I'm running into is the Flex Value Objects -- they pretty much have to be compiled into the .SWF file, which means we're stuck modifying source-code and re-compiling for each individual show. Not the solution we want. Is there a way to dynamically create and/or modify Value Objects so they can be changed without re-compiling the .SWF file? So that if a particular client wants stuff tracked that a different client doesn't want tracked, we don't have to create a generic version of our database that has all these extra fields in it, which most clients don't need? As it stands right now, the Value Objects force us to make every database for every show exactly the same -- unless we modify the Value Objects for each individual show and re-compile a separate .SWF file for that show... If there were a way to write, say, an .XML file that the program could read and modify itself accordingly for each show, that would be brilliant. Is there a way to do that?

[flexcoders] Re: Dynamically create a Value Object...
I should also mention we're using CF9 on the back-end. So the VOs have to be defined in .CFC files as well. So if anyone can tell me how to do dynamic VOs in both CF9 and Flex, that'd be wonderful. Alternatively, if there's a way to transfer data between Flex and CF9 that doesn't involve VOs (but is still strongly structured and typed, like VOs are), then perhaps we need to do it that way? I'm extremely confused here... I've written this program from the beginning with statically-defined VOs, and now I discover that that's just not going to work. So if anyone can point me in the right direction to help me learn what my alternatives to statically-defined VOs are, I'd really appreciate it. I have found a couple of blog posts about bindable dynamic value objects, but only how to create them in Flex -- not how to export the data in them from Flex to CF9. And the posts are pretty darn confusing, anyway... Heck, at this point I'd be willing to PAY someone to teach me how to do this, one-on-one. I really need someone who's an expert in both Flex 3.5a and ColdFusion 9.

Re: [flexcoders] Dynamically create a Value Object...
Hi Laurence, I'm pretty new to Flex so there might be reasons to stick with Value Objects that I'm unaware of but you can definitely read and write XML and generate forms, layouts, etc on the fly based on the XML contents. I've used E4X to query XML data that I've sucked in from an HTTP call, modified the XML using E4X and pinged it back up to the HTTP server to save the XML data for later use. Hope that helps...

Re: [flexcoders] Re: Searching through an ArrayCollection of Objects
Thanks for the replies... How can I find out what's going on behind the scenes with IViewCursors or ListCollectionViews? Do they actually index the Collection data to make the filter super fast or do you think it's comparable if I'm just looping and searching using a brute comparison? I only need to find the first match but I'm looping the ArrayCollection of Objects about 50 times as I'm using it as a kind of Lookup Table. Perhaps I should implement a specific Class to cache/index the Collection to make the lookups quicker. M.

Re: [flexcoders] Re: Dynamically create a Value Object...
You could probably try having a base VO for all the properties that you know will be there and include a single property in the VO which would be either a Dictionary or a generic object used as an associative array to handle all your custom properties. Then just populate the VO like you normally would and when it comes to extra properties, throw them in that one extra VO property. You'd have to have some kind of parsing method on both ends but I'd think this would work without too much trouble. -Jake On Tue, Mar 2, 2010 at 3:21 PM, Laurence lmacne...@comcast.net wrote: We're using an SQL database with a ColdFusion intermediary between the Flex app and the database...

loading progress as a debug tool.
What I find is that the textField _always_ updates correctly in
realtime, but USUALLY the progress bar does NOT update at all until the
entire sequence is finished. If I make the tick time long enough, then
the progress bar works, but this time seems very dependent on
performance of the individual machine.
My question is, how do I know what the lowest possible tick time I can
use to make the progress bar update correctly is? Why does it work with
the Text field just fine? Or is there a better pattern I could be using
to do this correctly?
As you can see from the code, I tried some things like
updateAfterEvent and invalidateDisplayList to see if I could get it
to update faster, but those did not work (unless I set the tick time
high).
code here:
private var pendingElementsToAdd:Array;
private var totalElementstoAdd:int;
private static const TIME_BETWEEN_ADDS:Number = 20;
private function addElements(newElements:Array):void
{
this.pendingElementsToAdd = newElements;
this.totalElementstoAdd = this.pendingElementsToAdd.length;
var newEventTimer:Timer = new Timer(TIME_BETWEEN_ADDS,
newElements.length);
newEventTimer.addEventListener(TimerEvent.TIMER,
onTimerAddNewElement);
newEventTimer.addEventListener(TimerEvent.TIMER_COMPLETE,
finishAddingElements);
newEventTimer.start();
}
private function onTimerAddNewElement(event:TimerEvent):void
{
this.loadingBar.setProgress(this.totalElementstoAdd -
this.pendingElementsToAdd.length, this.totalElementstoAdd);
this.loadingText.text = Elements To Load: +

[flexcoders] Problem with VideoDisplay orizzontal reflection
Hello everyone, I write because I have a problem with the item VideoDisplay in Flex. A hypothetical mx:VideoDisplay id=videoDisplay width=400 height=300 / how do I reflect it horizontally? So basically the right side should become the left and the right the left. I tried to input a negative width but the app crashes. Can you help me? Thanks
[flexcoders] Java.net and now FLEX Rescue Mission on March 5th
Hi Folks, For those who didn't followed Sonatype blog, this Friday (March 5th) Sonatype will be organizing an major effort to migrate projects hosted Java.net maven repository to maven central. http://www.sonatype.com/people/2010/02/java-net-maven-repository-rescue-mission-on-march-5th/ We would like to extends this invitation to Flex projects. So if you run an open source Flex project and wanna see it hosted inside Maven Central Repository, that is your major opportunity. On March 5th, 2010 Juven Xu and Marvin Froeder from Sonatype will start servicing any and all requests from Java.net projects to migrate their Maven Repository infrastructure over to our hosted Nexus OSS instancehttp://oss.sonatype.org/. We will, of course, continue to service requests after March 5th, but March 5th will be set aside to specifically help Java.net projects get switched over and tested. You will also find Juven and I on IRC during the entire day. irc.codehaus.org #mavencentral Projects that use ant, but wanna go to maven central and make Flex/Maven developers happier can also join on this guest. See you on Friday. VELO
[flexcoders] Re: Dynamically create a Value Object...
Thanks for the suggestion... I may be able to make that work... If I understand you correctly, I'd need to return an array-within-an-array kind of thing... My normal array of VOs, with one property of each VO being an array itself... Sounds easy enough... But I've tried before to get CF to do that (for a different problem), and failed... Does anyone know how to get CF to return an array-within-an-array kind of structure? I kept getting weird errors the last time I tried something like that - it kept acting like I was trying to create a two-dimensional array, when I only wanted a 1-dimensional array nested within another 1-dimensional array... So obviously I was doing something wrong there...

[flexcoders] Re: Dynamically create a Value Object...
First, let me say that I have been roundly criticized for taking the approach of NOT using VOs. Second, I use .NET FluorineFX. Having said that, I created my applications in such a way that my middle tier has a few generic methods for querying, updating, inserting data from a DB (usually Oracle). There is also a generic middle tier routine to handle stored procedures as well. My presentation layer, Flex, builds a SQL statement, and passes it to the generic middle tier that processes it (generally just passes it to the DB), and returns to Flex either an array collection (fully typed), if it was a query, or the results of the non query sql statements. If one were clever, using the approach above, one could create a Flex app that requests a table structure from the DB, and builds a data entry screen on the fly. You may want a schema table that contains data validation type info that would be read in conjunction with the table structure to allow edits to be performed by flex. When complete, all you would need to do is modify the DB to create the table structure the customer needs, and add records to the schema table, and you have a new data entry module. By the way, my main reason for resisting the VO structure, is I thought that keeping multiple copies of the VO in sync would be a PITA. Anytime you modified a table you need to modify at least two VOs, and potentially recompile middle tier and presentation layer programs.

Re: Re[flexcoders] strict user input in TextInput
I’d call preventDefault() on the textInput event.

How would I achieve the task of restricting user input based on the current contents of the TextInput? I am aware of the restrictChars property but that doesn't help since it applies a blanket rule as to which characters are allowed/not allowed. An example here would be: allow the user to input a number with no more than a precision of 2. In this case, as soon as the user enters 12.34 any more keystrokes in the TextInput should become no-ops. I did try adding event listeners to the KeyboardEvent.UP_KEY and KeyboardEvent.DOWN_KEY but it seems that you can't stop the propagation or prevent the default of keyboard events. Any suggestions here would be very much appreciated. TIA, sasuke -- Alex Harui Flex SDK Team Adobe System, Inc. http://blogs.adobe.com/aharui
