Flex :: Set ComboBox Prompt Property To Empty String?

Jun 15, 2011

Here is my code:

<mx:ComboBox prompt="" editable="true" dataProvider="{tableSelector.list}"/>

When this code executes, flex just sets the selectedIndex to 0 and displays the first item in the dataProvider instead of leaving the text and prompt as the empty string "". How do I get around this? I need the text property to be "" unless the user selects another item in the combobox.

Xml :: Flash - Run If/else Statement To Check If XML Node Is Empty?

Feb 23, 2010

checking an XML file for a specific node.

Example:

<vid
flv="videoName"
thumb="thumbnail.jpg"
title="Video Title"

[code]....

The first vid node contains a path to a logo graphic, I then need to check in my ActionScript if there is a logo there or not, and to do something if there is(display the logo) I can trace out the logo path so I thought I could run a simple if/else to check if there is anything in that node and if so to do something:

private function thumbOver(e:MouseEvent = null):void
{
trace("
");

[code]....

Now I've tried everything, but it will always trace out "Does have a logo" no matter what I do. I tried:

if (tabData[tabID].video[e.target.id].@logo == "")
if (tabData[tabID].video[e.target.id].@logo == null)

However I get the same results?

ActionScript 3.0 :: Flash Check Container And AddChild If Empty

Apr 7, 2011

I have a button on stage which has a child menu movieclip and that movieclip has three submenu button children.On each of these 3rd level buttons an event listener draws a new container on the stage and adds a new movieClip holding various info.This all works nicely, but I cannot work out a way to get an eventListener on the menu buttons to check if the container already exists so I can then stop the button repeating the add container function. So, at the moment you can repeatedly hit any of these menu buttons and they will just continue to add info movieClip children.I've tried some nice Boolean commands that should work, but I think it's the nesting of the children/relationships that are not allowing me to get this to work.So, basically for arguments sake, let's say I only have one of each item... here's the nesting of children:[code]

Regex :: How To Parse String (Similar To Path)

Mar 4, 2010

I have a string that is similar to a path, but I have tried some regex patterns that are supposed to parse paths and they don't quite work.

Here's the string
f|MyApparel/Templates/Events/
I need the "name parts" between the slashes.
I tried (w+) but the array came back [0] = "f" and [1] = "f".
I tested the pattern on [URL] and it seems to work correctly.

Here's the AS code:
var pattern : RegExp = /(w+)/g;
var hierarchy : Array = pattern.exec(params.category_id);
params.name = hierarchy.pop() as String;

ActionScript 2.0 :: Converting String To ASCII Or Similar?

Dec 22, 2003

In Sweden we have these characters (and of course also in caps). But my MySQL db can't store characters, so if I look in the db and search for my name, Bostm, i can't find it..The search is ran from within flash (mx2004, and from there to a php-script, wich then sends the matching row back to flash.I want to convert all thein a string, and to be able to reconvert them when flash gets the string back... So the string should be stored in the db with the encoded...(am I confusing you now?)And I can't use the html-code for 'cause if the php-script prints this: Wow... quite an explanation...Ok, short summary:

AS-sting: Bostrm
>encode (so that =ASCII or so)
>send to PHP-script

ActionScript 3.0 :: Way To Check If String Is Longer

Feb 22, 2011

I have a regular expression in my code. What I want it to do is to check user input. This input should be a string of 9 numbers with spaces between them. So for example "1 2 3 4 5 6 7 8 9" should return true, but also "123 45 2765 23 3456 23 5 456 1" should be true. [code]My problem is that if the strong with number is longer, the usual test method still returns a true. Is there a way to check if the string is longer then this?
