as3, chargedweb, com, package
May 05jloacode
I’ve decided to make a sort of a mini package containing some handy utils (but not only) classes in one place.
Includes such classes like: VectorUtil, ResourceMonitor, MatrixUtil, LoaderUtil, Cache, VimeoPlayer, SkypeStatusIcon etc.
Download the com.chargedweb.* package
UPD1: now with docs
UPD2:
- added AlignUtil class (more info here)
ps: i wish i had some free time to collect all my classes in one huge package 
as3, black'n'white, saturation
Mar 18jloacode, misc
Sometimes i need a fast black’n'white saturation method and this one’s the shortest i presume.
I can’t remember whose this method originally was, but it’s nice.
private var rc:Number = 1/3, gc:Number = 1/3, bc:Number = 1/3;
private var sf:ColorMatrixFilter = new ColorMatrixFilter([rc, gc, bc, 0, 0, rc, gc, bc, 0, 0, rc, gc, bc, 0, 0, 0, 0, 0, 1, 0]);
private function blackAndWhite(target:UIComponent, enabled:Boolean):void
{
if(enabled) target.filters = [sf];
else target.filters = [];
}
as3, cursor, CursorManager, flex
Mar 12jloacode
So there i was, trying to build my latest application which involved run-time cursor loading/usage.
I knew that the flex sdk had that static CursorManager class (i.e. mx.core.CursorManager), but as i looked up the manual – there’s no loadIcon() method, only setters that require class references which is sooooo unhandy if u deal with run-time loading assets (like i do).
So, i got myself some coffee, opened the eclipse and after some time spend – eureka!
I came to this slight solution which besides is elementary.

as3, class, skype, status
Feb 22jloacode
Today i had some free time to make a skype status icon class (don’t know who’d need that).
Anyways, it’s a simple class that connects to the skype service, retrieves the status code for a specified account name and displays the status icon. All parameters customizable. I’ve even created a sample page with a php proxy (see the archive)

as3, flex, icon, load
Feb 20jloacode
The only thing why flex sucks is that components can’t actually load icons (Button class for example) i thought.
Yes, but that was until i found Ben Stucki‘s slight solution to this issue.
He wrote a nice utility class called IconUtility which creates BitmapAssets at run-time. This class is huge.
Sample button icon load up code:
var myBtn:Button = new Button();
myBtn.label = "press me";
myBtn.setStyle("icon", IconUtility.getClass(myBtn, "assets/my_icon.png"));
addChild(myBtn);

as3, sort, sorton, vector
Feb 20jloacode
As you probably know the new fp10 api provides a new Vector class (wonder my didn’t they just make typed Arrays like in C#) that increases performace about x2 times.
But, still among with the performance you could face some difficulties working with Vectors, for example it doesn’t implement a sortOn() method which, i think you’d agree, is very handy.
UPD: lots of people use very strange/complicated methods to sort vectors.
Guys, stop complicating yr life – the task is way much easier.
So, here’s how i do the sortOn() with Vectors:
/**
* Converts vector to an array
* @param v:* vector to be converted
* @return Array converted array
*/
function vectorToArray(v:*):Array
{
var n:int = v.length; var a:Array = new Array();
for(var i:int = 0; i < n; i++) a[i] = v[i];
return a;
}
/**
* Here's a little example on how to sort a Vector using sortOn
*/
var v:Vector.<Object> = new Vector.<Object>();
v.push({id:5, email:"andrew@someweb.com"});
v.push({id:35, email:"david@someweb.com"});
v.push({id:12, email:"jill@someweb.com"});
// now to sort the Vector on the "id" property
var vSorted:Vector.<Object> = Vector.<Object>(vectorToArray(v).sortOn("id", Array.NUMERIC));
// easy and convinient isn't it? ^_^
Hope might be useful.
Cheers

as3, captcha, class, validator
Feb 20jloacode
Some time ago i was surfing the net and i noticed that flash captchas are very popular on such components stores like flashden etc, but just few of them are actually made properly and can prevent spammers from doing their magic ^_^.
So, i’ve decided to write a little sample catcha validator class for those of u that need or would need one.
