Validating real/integer numbers in Flex
Written for: Flex
Below is a short code to determine whether a number is real (floating). To find if a number is an integer, change the domain property in NumberValidator tag from “real” to “int”.
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
layout="vertical">
<mx:Script>
<![CDATA[
import mx.controls.Alert;
]]>
</mx:Script>
<mx:TextInput id="myTxtInput"/>
<mx:NumberValidator id="myNumberValidator"
domain="real"
source="{myTxtInput}"
property="text"
trigger="{myTxtInput}"
triggerEvent="focusOut"
valid="Alert.show('real number')"
invalid="Alert.show('hmmm....unreal number?')"/>
</mx:Application>
AS3.0: Add one or more elements to the begining of an array
Written for: ActionScript 3.0
To add one or more elements to the begining of an array, you will have to use unshift method of Array class.
Below is an example.
var albums:Array = new Array("Natty Dread","Rastaman Vibration","Exodus","Kaya");
albums.unshift("Catch A Fire");
trace(albums); //Catch A Fire,Natty Dread,Rastaman Vibration,Exodus,Kaya
Bombay – (Rickshaw or Taxi) = Beautiful Bombay
I had the most pleasant ride to work today. The reason being – there were absolutely no god damn rickshaws or taxis on the streets of Bombay. The reason for that being – they had a stupid strike (The hardship of which will never be known).
To see Bombay, devoid of rickshaws or taxis is unimaginable. But, the “emptiness” on the streets is so beautiful. I could never picture a ride without cussing the rickshaw and taxi fellas. (I cuss at other vechiles too)
I hope someone figures out a way to keep this “emptiness”. (Focusing and improving public transport would be a very good option)
Okay, I got a ride and I’m a mean selfish bastard.

Dynamically add element / attribute to a XML using E4X
Written for: Flex, ActionScript 3.0
To dynamically add element / attribute to a XML; assume that it already exists in the XML and using the .(dot) operator, pass a value to it.
Here’s an example. Consider the following XML:
var albumXML:XML = <tracks> <song tracknumber="1"> <title>Orgasm Addict</title> <artist>Buzzcocks</artist> </song> <song tracknumber="2"> <title>What Do I Get?</title> <artist>Buzzcocks</artist> </song> <song tracknumber="3"> <title>I Dont Mind</title> <artist>Buzzcocks</artist> </song> <song tracknumber="4"> <title>Love You More</title> <artist>Buzzcocks</artist> </song> </tracks>;
To add an additional element of <genre> to the first <song> node, I’ll use the following line of code.
albumXML.song[0].genre = 'Punk';
Similarly to add an attribute of duration to the first <song> node, I’ll use.
albumXML.song[0].@duration = '2:00';
trace(albumXML);
/*
<tracks>
<song tracknumber="1" duration="2:00">
<title>Orgasm Addict</title>
<artist>Buzzcocks</artist>
<genre>Punk</genre>
</song>
<song tracknumber="2">
<title>What Do I Get?</title>
<artist>Buzzcocks</artist>
</song>
<song tracknumber="3">
<title>I Dont Mind</title>
<artist>Buzzcocks</artist>
</song>
<song tracknumber="4">
<title>Love You More</title>
<artist>Buzzcocks</artist>
</song>
</tracks>
*/
Additionally, you can use the following methods of a XML object.
- appendChild()
- prependChild()
- insertChildAfter()
- insertChildBefore()
hmmm…Thats easy!
Found this video on YouTube under the title – “The Art of Starting a Royal Enfield (1)”. Being a hardcore Enfield rider myself, I was expecting a kick start with a lot of back kicks thrown in for that extra punch. What I found in the end was really funny. Check it out.
By the way, only Enfield riders would understand this. Others can just ponder over our amusement!
LHC – Ohh Yeah!
I know I’m delayed by a couple of days, but still considering the enormous nature of the project and the scientific significance I would like to say – “Collide those damn particles and lets see what we get!”
