ActionScript 3.0 :: Decorater Pattern Vs XML Database?
Apr 26, 2009
I wanna ask about the usefulness of this decorator pattern.Decorator pattern allows user decorate an item with different unique things.But what if there are 800 items to decorate the main component?That would lead to 800 subclasses under abstract decorator.Would XML as database shine in this area?Whats the point of having decorator pattern in the first place when we could just use arrays and a storage for item information such as prices in XML?
Arrays can do all the things that decorator can do, and further more uses a few XML easier to manage compare to 800 classes, although its against the concept of "close for modification"
i'm trying to search a string for a particular pattern, and replace it with elements from within the pattern... for example..here's the given string...if you want to learn how to use regexp, {url===http://somesite.com, text===click here}.
the pattern... {url===http://somesite.com, text===replacement text}
and the intended result... if you want to learn how to use regexp, click here.
of course, i'll extract the url and do something else with it... i'm just wondering what the regexp is for that pattern, and how i can extract things from the results returned.
i want to intertwine php, MySql and flash. so i can make a flash movie display text that is in the sql database and a php script to change the database, php > sql = i can do but sql > flash = i can't do..i want it so the sql data show's in a text box in the flash movie...
I want to create a Flex 3 application running in Adobe Air that accesses an SQLite database and I need to keep this database in sync with an SQL server 2005 database running a website.Is this something that Flex supports or is it going to be a custom script? Also, has anybody done anything like this?
Edit: The synchronisation can be done on a daily basis rather than real time. The data will be read only from a front end perspective with a CMS to do updates on the website.
I have researched this issue all over and most people say use the .refresh() method to update a datagrid after updating or adding a new record. This does not do anything. So, my issue is this. I have a mySQL database hosted I am connecting via PHP, I have 1 mxml file and 2 php files (I know I can use just 1 but I am learning and this was easier for me to use for troubleshooting). The issue is no matter what I change on the datagrid the update does not show on the datagrid unless I close out of IE and reopen it. I can refresh or open the page in another window and the update does not show. I have to exit entirely and restart in order for any updates or additions to show.Here is my licenseTracker.mxml
I am working on a function to generate a form at runtime in Flex based on a call to the DB. The call to the DB returns the field types, id, tooltips etc as an arraycollection, the arraycollection is then parsed in order to ascertain what control to display based on the type field in the array - this bit works fine.However, i am stuck on trying to save the form fields back to the database using a CFC.my form rendering code is as follows but how do i save values entered back to the database? rendering code..
[Bindable] public var getglobalprofileb:ArrayCollection; public function init(event:ResultEvent):void {[code].......
I have updated the mxml code to only show the needed code for the program to run the update.
I am new to Flex and have an issue I hope you all can help me out with.

I am planning on using Flash Builder 4/Flex to write an AIR application which is primarily based around recording, storing and analyzing data.I'll be creating charts etc that need to update in almost real time.It's essential to me that the application be able to function without an internet connection so I need a local database of some variety,but I would also eventually like to build in online synchronization of the data where either database can be update each other based on newer information. Moreover, some type of encryption would definitely be welcome, and speed is a large concern
Synchronization: Primarily updates/additions/deletions will be done on the offline database, but ideally I want to have a web interface that will allow the same updates/additions/deletions and will be synced (beyond that I'm not sure exactly how to do it as I can model that based on what is most achievable).I'm wondering if there's any prebuilt engine that could handle the synchronization of 2 databases. I may end up having the web interface only be for additions, which would be significantly easier to sync.. and I may start that way, but i want to build with technologies that will best allow me to implement full online crud at some point.
Here is the issue: a client wants his entire equipment inventory accessible by persons navigating to his jquery mobile site. The inventory that exists on the desktop site was, as I understood, built with Flex. Is it possible to access this database for the jquery mobile site? I believe it is. I was then given this information from someone in the know:
Is it possible to create a database driven website using these alone? Or do i need to learn any other technology? If i do then what should i learn? I know j2se for the desktop and oracle SQL/MySQL i finally got the feeling that i need to learn PHP anyway along with css and javascript. So it is fine. Also another query. Which CMS should i consider? Wordpress or Joomla?
I am planning to develop a standalone application, which infact will be used for personal purposes. So only single user access may be there. I want to develop it in Flex. Just want some opinions from the gurus over here : Whether i should use Flex or AIR (I know only Flex, AIR i need to start learning)Which database i should use? SQLLite or HSQLDB or some other.
I have a database on a server and I transfer the data from it to a web site. So I need to build a flash grid on this site and to load the data on it. But the problem is that I do not know how to do it. So my question is how to build a dynamic flash grid wich is fill with data from a database? Is there a way to do it with action script only or I must do it another way?
I am writing a large flex app that has to connect to a database many times. I currently am using asp pages to connect, but I would like to use the most efficient option. What do you think is the best way to connect to a database from a flex app?
I can't understand why should I even use the Singleton pattern in ActionScript 3. Can anyone explain me this? Maybe I just don't understand the purpose of it. I mean how it differs from other patterns? How it works? I checked the PureMVC source and it's full of Singletons. Why are they using them in the View, Module, Controller?
I am working on a Flash project that initially had a simple template for the animation, but has grown to have different "states" with multiple templates (not under my control)Because of this, my update (ENTER_FRAME) loop is now starting to look a bit like this:
private function update():void { switch (state) { case "intro": switch(layoutState) {
I remember seeing someone a while back using actionscript a method to draw a pattern. I thought it was a really interesting take on as and kept in the back of my head for when the possibility came up.
If I place a pattern or object over a 3d object created in CS4, will it affect it by warping it in any way.I'm looking for a way to push a pattern over a 3d object, for the pattern to look like the 3d object is "under" it.
I would like to create a repeating pattern using a bitmap from my library as a background. I would like the pattern to always fill the stage area when the brower window is scaled. The code below works, but I think it may not be the most efficient way to handle this. Seems to be a little slow.
function onResizeStage(evt:Event):void{ backGroundSprite.graphics.beginBitmapFill(pattern(0, 0)); backGroundSprite.graphics.drawRect(0, 0, stage.stageWidth, stage.stageHeight); backGroundSprite.graphics.endFill(); }
How can I find a given bitmap pattern on a bitmap ( loaded jpeg )? Is there any flash classes / functions for this purpose?Here is the sample image and has 4 patterns.What I want is to get the bounding informations of the 4 patterns on the image ( x , y , width , height ).
I'm looking to get some good books on design patterns and I'm wondering what particular pattern you'd recommend for a Realtime Strategy Game (like Starcraft), MVC?. I'd like to make a basic RTS in Flash at some point and I want to start studying the best pattern for this.
Just curious. TweenLite/TweenMax is a very common animation library, and I was wondering how someone would classify the design pattern used in TweenLite.For those of you unfamiliar, here's some example code from their website:[code]
I plan to have the swf fill the browser window, and this should work fine for that. When people click on a button, I want the view to "zoom in" by scaling to 200% and setting the x and y coordinates appropriately.How can I do this with the repeating pattern, because the way I have made it is a series of movieclips. Is there a better way to make it so it is just one movieclip I can control the scale and position of?
ActionScript Code: tileWallpaper = function () { tileWidth = 200;
I have a model which manages all of my data (DataManager)
I have a series of view classes, which manage stage instances.
I would like my view classes to listen for custom events within my DataManager class. So, for example, when all of my data files are loaded, I would like to have a custom event dispatch. All of my views will have listeners within them, waiting for events from the DataManager to trigger functions within.[code]...

I started 2 days ago programming in as3, so I'm building a website and I want to create a pattern for my background.The pattern is a bitmap image 300px X 300px and I want to repeat it along the x axis and y axis of my document.My stage is 1280 x 800)And I want also to have the pattern to fill all the screen in case of the user's screen become larger than the resolution of the stage that I'm building the website on.
