I've just taken over a project from another developer and the code has a lot of if statements like this:
[Code]...
Which while ok, does get a bit messy when used everywhere. Is there a better, neater way to write this? I was thinking of this
[Code]...
If I parse an XML element with a null or undefined result, is it possible to display a blank text field rather than "null" or "undefined" in the field? It seems really basic but I'm drawing a huge blank.XML
Code:
<content>
<item></item>
[code].....
ok I dont get it... I have a simple contact form, and a basic if/else to check if certain fields have been left blank... if they have frame two displays an error message, if filled in then it posts the vars and goes to frame three thanking the user. For some reason this code ALWAYS returns false:
Code:
on (release) {
if (name eq "" or address eq "" or city eq "" or state eq "" or zip eq "" or phone eq "" or email eq "" or projects eq "") {
_root.gotoAndStop(2);
[Code].....
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at QuizApp/createStatusBox()
at QuizApp()
That's the error message I get when it tries to play. What I have is an swf that loads another when its done, the new swf is blank but has a document class to an AS file. It seems the problem lies when a function is not properly being added to the stage.
The function is added like this..
Code:
package{
public class QuizApp extends Sprite{
public function QuizApp(){
createButtons();
private function createButtons() {
if (this.stage == null) {
trace("STAGE IS NULL!!!");
} var yPosition:Number;
addEventListener(Event.ADDED_TO_STAGE, addedToStage);
...
I was wondering how to check an array for a blank index and removing it.
Right now I have this:
[AS]
function cleanArray (it)
[code].....
$output .="<keyword>".$_POST['keyword']."</keyword><name>".$row['url']."</name><occur>".$row['occurrences']."</occur><queryTime>".(substr($end_time-$start_time,0,5))."</queryTime>";
}

When working with Date() objects in Flex/Actionscript, I'm using to following function to check for null dates. Is this the proper way to check for a null date or is there a better alternative out there?[code]...
View 1 RepliesI have a form where a user can select up to three radio buttons and click submit. however if they don't select a radio from one of the groups (they dont care to answer the question or just missed it) the value of the radio button (I think) is null and gets returned as such using this code:
function Question1():Object{ return RadioButtonGroup(Q1R1.group).selection.value;}
Then, when they hit the submit button it sends the values to the database. This works fine, but only if they select a radio button for each group. If they missed one I get the following error:
"TypeError: Error #1009: Cannot access a property or method of a null object reference. at mid_fla::MainTimeline/Question1() at mid_fla::MainTimeline/clickHandler()"
When I did a trace on the value of Question1() it returns function Function() {}
how to check if the value returned is a null object reference or whatever and give it a default value if it is?
I have a weird problem. An Object is being passed to my function, and some parameters are optional, so naturally I would check to see if they are there, and if not, do nothing.However, I'm getting a null reference error (#1009) when I'm just checking it. Here's the sample:
public function parseObject(params:Object) {
if (params.optionalParam)
trace("Got Optional Parameter!");

I'm using the native Flash StyleSheet Object to hold externally loaded CSS styles, and when I run the the getStyle("myStyle") function of the StyleSheet Object, it returns an Object in all cases, even when the style doesn't exist!
In cases where no style is found on the StyleSheet, the ASDocs say that the getStyle() function should return null. So if "notAStyle" is not a style on the StyleSheet, and I test[code]...
I have begun on a list: My reference is null!Stage is null! Convert this code from as 2 to as 3 for me! Crossdomain policies are in the way of my cool idea Dynamic property names I need to use stuff on the parent! I don't want my children to scale when I scale the parent! Classes vs instances.

the script i wrote is working fine. but the script attached to the flash player which i have no control over is throwing a script error (im using IE8).how can i fix this? if i run it locally there is no error.
'null' is null or not an object
try { document.getElementById("").SetReturnValue(__flash__toXML(function() { return document.location.hostname; }()) ); } catch (e) { document.getElementById("").SetReturnValue("<undefined/>"); }
but this is from flash script and i dont have control over it. it just say JScript - script block.

sometimes I remove child and trace it afterwards and it outputs null although I havent yet set it to null, why is that? and do I need to set it to null also in that case?
Code:
trace(holderArr[loadedThumbs].getChildByName("photo_bg"));
//[object MovieClip]
holderArr[loadedThumbs].removeChild(holderArr[loadedThumbs].getChildByName("photo_bg"));

I have the following piece of code(part of a much bigger program). I this code I am re-using a motion that has been previously used successfully. The trace stmts are used to identify the exact location of the error and the error conditions as best I can.[code]
View 4 RepliesWhen you cast null to an object using Object(null), the result is an object.When you cast undefined to an object using Object(undefined), the result is an object.But saying null as Object or undefined as Object remains null.Why is this? I can't find anything in the documentation about this.
The objects that result from these casts can have properties set on and read from them. It's as if the cast created information, or removed whatever special information the null and undefined values have. But there's no indication in the AS3 documentation that the null and undefined special types are actually objects.

See [URL] Now there is a button called Answera, which when clicked should have a symbol (movie clip) called Check appear at the cordinated specified. Check exists in the libary (but does not have an instance name) and no where else on the stage. when I run this code I get: 1180: Call to a possibly undefined method Check. -> var rightCheck = new Check(); How is it undefinded if it exists in the libary?
View 7 RepliesThe following is my codes. This is still work in progress; so, you will see some functions with empty contents. Plus, this is my first Flex application; please bear with me. This is a quiz application that gets the questions and answers to each questions from a ColdFusion web service. There are three types of questions, True or False, Multiple Choice with single selection, and Multiple Choice with multiple selections. So, based upon the question type, the application would dynamically generate the appropriate amount of radio buttons or check boxes for the users to select. I got these working. The problem that I am having is, I am not sure how to check what the users have actually selected. In some other forums and posts on other web site, it said that I can use event.currentTarget.selectedValue to get the user selection. But when I actually do it, I got a run-time error saying, "Property selectedValue not found on mx.controls.FormItem and there is no default value." My question is, what do I need to do to capture the user selections?

I am trying to add an EventListener to a MC, but I am getting the 1009 error. My script is referencing a MC that does exist. I have verified that my code is typed correctly, and that my instance names are correct.I am creating a portfolio site. On the first frame I have my main navigation (well, it's actually not the first frame. I alpha-fade everything in so it's really the 6th or 7th, but I'm not sure how pertinent that is). The main navigation works fine (5 movie clips, fyi). Clicking them will move to a different frame, and the information and sub navigation for the frame will fade up. It is the sub navigation that I am having trouble with.[code]
As you can see, it doesn't even get to the function before it gets thrown off. I have verified that the instance names are correct. The script and the MC I am trying to add it too [I/]are[I/] in the same frame, which is what's stumping me. Normally you get 1009 when the object you're trying to reference is not there, but mine is!!Obviously there is something wrong with my EventListener. I am not sure what else do; there is a gap in my understanding of AS.
If I set an Object = null, does that remove all references to the Object's variables assuming there are no external references to said variables? Or do I have to manually set all said variables = null?
View 4 RepliesSo I made an animation a while ago and exported it no problem as an .avi. Recently I've needed to make changes, but whenever I try to export it, it is a blank video.
There is no sound, so I'm not sure whether or not that is working, but the video turns out as just a black movie with the proper length.
When I test it in flash or export it as a .swf, it is fine, only the .avi is the problem.
I'm trying to make a simple Flash application to be placed on a web site. It is intended to take data from an .xml file and display it in the Flash movie. There are a number of buttons that display different nodes of the .xml file when clicked. (Not all the buttons are functional yet in this code; I know that.)It runs just fine in Flash. It even runs fine when I publish it and then run it by clicking on the html file on my computer.When I upload the html and swf files to my server, the html file works fine (gives me a solid colored background) but the swf is just a white box, nothing in it and no functionality.Something needs to be declared, imported or linked, I think, but I do not know what or how to do it. (Most irritating is the fact that the code is substantially taken from an online tutorial, with nary a word about this issue.)
