OSX 5005:Unknown error optimizing byte code

admin — Tue, 31 Aug 2010 12:29:55 +0000

Working in a large AIR project, the flash compiler give me this strange error:

1	5005:Unknown error optimizing byte code

To avoid it , we must increase the memory of the compilator by creating a file in:

1	~/.MacOSX/environment.plist

and put this text in it:

1
2
3
4
5
6
7

JAVA_TOOL_OPTIONS
-Xmx512m

If you use flash CS5 also edit this file:

1	~/Library/Application Support/Adobe/Flash CS5/en_US/Configuration/ActionScript3.0/jvm.ini

Then change -Xmx128m to -Xmx512m

AS3 Condicional Switch Stament

admin — Wed, 28 Apr 2010 15:55:37 +0000

Imagine we can use switch staments with conditional operators other then strict equality.

This way we can do a code like this:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18

var value:int = 2;
switch(value){
case < 1:
trace("Value is less than 1");
break;
case 2:
trace("Value definitely equals 2");
break;
case >= 3:
trace("Value is greater than or equal to 3");
break;
case > 1 && < 3:
trace("Value is greater than 3 and less than 5");
break;
case !== 5:
trace("Value definitely doesn't equal 5");
break;
}

Navigating the web I have find one solution:

var value:int = 2;
switch (true) {
case value < 1:
trace("Value is less than 1");
break;
case value == 1:
trace("Value equals 1");
break;
case value > 1:
trace("Value is greater than 1");
break;
}

innerHTML removes attribute quotes in Internet Explorer

admin — Sat, 20 Feb 2010 01:38:57 +0000

After losing 2 hours for an unknown XML parsing error, I have discovered that the results of innerHTML in Internet Explorer are wrong.

// Original Source code of document
id="container">container>
// Result of innerHTML in document.getElementById('content')

//Firefox
id="container">container>
//Internet Explorer
id=container>container>

The solution: innerXHTML

1 2	var container = document.getElementById('container'); var code = innerXHTML(container);
