I have written a basic chat client that talks to an XML Socket server. When it starts it connects to the socket and works fine. However, when I close the Flash Player it is still occupying a connection to the server. I am trying to determine how I can trap the close of the Flash Player and programmatically close the connection to the server before the program exits.

From a Flash object, I would like to be able to detect the presence of a webcam that the user might grant access to, without actually asking the user whether they want to grant access. This is to streamline a large application that has extra features if a webcam exists — if there is a webcam, the application will present several dialogs that lead up to the normal cam-security prompt, but if the user doesn't have the hardware, I want to skip over them altogether. Requesting access to the cam before those dialogs won't make sense to the user.
It appears not to be possible to call Camera.getCamera() without the security prompt happening. Is there a workaround? (For instance, could I, perhaps, call getCamera in a hidden Flash object and inspect its return value, or does it block until the user acknowledges the security prompt?)

I have a gallery loading jpegs from an xml file into a mc called mainPicArea, on frame 5. I have other content on frames 1,2,3,4,6,7.
I want to run an if statement to check whether mainPicAreaexists and if it does, then run a removeChild(mainPicArea), and if not do nothing.
[AS]
if (MovieClip.mainPicArea){
trace("exists");
//removeChild(mainPicArea);
[code]....
When I test, it comes back with the trace "doesent exist", even though it does exist.

Is there a way to see if a class exists? something like:
if( MyClass exist in the Library or has been imported in to the class ){
var myClass = new MyClass()
addChild(myClass);
}else{
trace("MyClass doesn't exist")
}
I'm not trying to see if it exists on the stage just want to know if I have access to it.

Is there a way in flash to check to see if a function/method exists before calling it?
I tried something like if(typeof object.methodname == "function") and it didn't like it.

My page has 2 tab menus. When the page first loads, it defaults to the first tab, but when the second tab is hit, an image is loaded to the stage. I want to remove the image from the stage once the first tab is hit again.I keep getting the error "Access of undefined property Image1" but the whole point is to check if this child exists with the if statement.
//Tab 1
if (Image1 != undefined) {
stage.removeChild(Image1);

I have a Dynamic text field embedded into a movie clip on the same frame different layer there is some action script. A series of If statements Which is basically to see if text field contains text so if it dosent contains text I can assign text to the text box
if(orderMenu_mc.Item2_txt.text == "")
{
emptyText = 2
trace(emptyText+"Hello")
}
There is no text. Yet the if statement is false. Is this a logic error or is there a better method of achieving this PS i have tried orderMenu_mc.Item2_txt.text.length == 0 which also evaluates to false when there is no text in the field.

I am working on a software which takes .ppt as its input and produces .swf file as its output.
When I was dealing with fonts, I found there is slight difference between the representation of the text in .ppt and .swf though the font name and size are same in both.
The difference increses when I make the text bold or italic or both.
I want to know why such differerence exits?
And what should I do to make the.swf font representation same as that of .ppt?

I have an input field that asks for a .swf name - you enter the name, hit SUBMIT, and Flash loads that .swf onto the screen.I've coded for an error to appear if the user doesn't input anything, but how to I test to see if the swf exists, and if not, return an error?I have a function called onSwfLoad that runs when the swf loader finishes, triggered by anEvent.COMPLETE in the swf loader event listener - is there something I can put in an if statement there to test if the swf loader found a file?

I have a movieclip created with the following code:
var thumbContainer:MovieClip = new MovieClip();
thumbContainer.name = "thumbContainer";
stage.addChild (thumbContainer);
If the window gets larger/smaller I want everything back in place. So I have an stage Event Listener. Now I want to see if this mc exists to put back in place. I've tried different ways but keep getting an error that does not exist.1120: Access of undefined property thumbContainer.
if (this.getChildByName("thumbContainer") != null) {
trace("exists")
}
and
if ("thumbContainer" in this) {
trace("exists")
}

I have a Rect object that I'd like to create and set its properties only once. After that, I want to just modify its properties since it already exists. This is my general idea
if(theRect == undefined){
Alert.show("creating");
var theRect:Rect = new Rect();[code].............
but can't get the desired effect. Everytime this code block runs, and depending on which version I've used, it either gives me a "can't access null object" error or the if statement always evaluates to true and creates a new Rect object and I get the "creating" Alert. What's the right way of creating that Rect but only if doesn't exist?

I'm getting the "Error #1009: Cannot access a property or method of a null object reference." error on my application. Is there a function I can use to detect this before it causes an error... maybe something like:
isValid(variableName);
I know there's one, because i've used it before, but i can't remember what it is right now.

I have an event driven flash program. I need to be able to call removeChild() if and only if an object is a child. getChildByName() and most other functions don't seem to allow for this and if you call removeChild() on an object that isn't a child it will throw an error. I suppose an option may be to catch the thrown error and just ignore it, but that seems like a bad solution.

I want to add the possibility to take a webcam picture to my project, but only if the user's system has a webcam installed (obviously). In other words, those without a webcam should not notice the new function at all.
So basically, I need to check if a webcam exists on the user's computer.
I found a couple of ways to accomplish this, but none seem to work when I test them on a webcam-less system.
* One way to detect the presence of a webcam is to check if (Camera.names.length > 0).
However, on my 'blind' (webcam-less) computer, Camera.names.length returned 1 nonetheless.
* The other is to check if (Camera.getCamera() != null).
If I understand it correctly, 'getCamera' is specific to Actionscript 3. My whole project is in Actionscript 2, I'm afraid it's too late to switch. The AS2 equivalent would be (Camera.get() != null). But I tested that on my 'blind' system and again, it didn't return null.
In short, both these methods indicated the presence of a webcam where there was none.
So my question is:
Is there a really foolproof way to detect the presence/absence of a webcam in Actionscript 2? Before the 'allow/deny' dialog pops up?

In my script I create a button that when clicked, creates a blue square. However, I want to remove any blue squares that exist before creating the new square (because as it is a low opacity square creating another one will make it more solid, as well it's just more objects that the system has to keep track of).Here is my code:.as

actionscript but have managed to load an external .SWF file into an existing flash file.I have a button that runs the following code which successfully removes the loader:
removeChild(myLoader);
SoundMixer.stopAll();
My problem is that if I click to go elsewhere my loader keeps playing.What code can I include on all my other buttons to unload the loader before going somewhere else in my flash file? I've tried just running the 2 lines above but get an error because sometimes myLoader doesn't always exist.
