Actionscript 3 :: Communicate Between An Instance Of Flash Embedded In A Browser And A Flash Instance Running In A C# WinForms App?
Dec 23, 2011
I am trying to communicate between an instance of flash embedded in a browser and a flash instance running in a C# WinForms app... I am getting a compile error that say:
1119 Access of possibly undefined property printOut through a reference with static type flash.net:LocalConnection
Here is the actionscript:
var feedback = "";
var receiving_lc:LocalConnection = new LocalConnection();
receiving_lc.connect("fromClient")

I have a Flash Player ActiveX control embedded in a .NET WinForms application and am trying to load a SWF into the FP control over an HTTPS url. In development I'm using a self-signed certificate and it seems that in this scenario I can't get FP to accept the certificate and allow the HTTPS communications.When I try to load the swf over https directly, I don't see the swf and when I right-click on the control I see "Movie not loaded". I can load the swf over http and then try to make Flash Remoting calls over https. I don't expect this to work by default but I added a crossdomain.xml file to allow insecure communications. The crossdomain.xml file is in the root of the server but is not loaded. I added an explicit call to loadPolicyFile with the full https url and the crossdomain.xml file is still not loaded. The local IIS logs don't show any request for the file at all, nothing in the HTTPERR file, and Flash's policyfiles.txt log says URl...If I host the swf in a browser, then the browser prompts to accept the certificate and everything works fine. I've accepted the certificate in IE and Firefox.I also tried calling DisableLocalSecurity() on the FP ActiveX control but it had no effect. I didn't really expect it to since I'm not actually loading the swf locally, it's loaded from a url.Can anyone confirm if the self-signed cert really is the problem? Is there a way to get FP to accept the certificate? Any way to bypass the http/https restriction (this is a locally installed app so I can change any local config files we need)?

Does creating a new instance of an Object that uses an identical name to an older instance, delete the previous instance? Or should the original instance be deleted first? The code uses a ridiculous amount of XML vars. Isn't it less memory intensive to parse the XML and save the properties to an Object, and then delete the XML Object, rather than keep the XML Object around and reference it's child nodes directly? Is it better form to break up a huge XML file (>600lines/3200vars) into smaller chunks?

I have a library object (SomethingMC) which extends a custom class (Something). Something, in turn, extends MovieClip.If adding SomethingMC to the stage within Flash CS3 IDE, is it possible for it's super class (Something) to assign an instance name from a class constant (Something.THE_CONSTANT)?
package
{
import flash.display.MovieClip;[code].....
The above does not work. It throws Error #2078: The name property of a Timeline-placed object cannot be modified. if the instance is assigned a name in the IDE, and it just doesn't work if no name is assigned in the IDE.

From the actions layer, I am trying to "talk" to a movie clip nested inside another movie clip residing on keyframe Two of that clip, not the first frame, the first frame is blank keyframe. It appears that Flash can only recognize (see) an object's instance name if it starts on the first frame?
As a work around for this, I put the same instance also on Frame One and change the movie clip's visibility (invisible) so AS can see it's instance name to make it work, but I feel there must be a better solution than this.

I've embedded a MovieClip symbol with the [Embed] syntax into my AS3 project, which I'm compiling with the Flex 3 SDK. That MovieClip has instances of other clips within it that are placed on stage with instance names. I can't just access them by instance name like I would if I were compiling with the Flash IDE. How can I reference them?

Determine, whether a defined program is running (for example firefox.exe) If its running, then get the current dimensions of its window - i want to make a screenshot of the window, so i'd need other parameters too i guess: Is it minimized? is it behind some other window?
Is this possible to accomplish in AIR? Im using the latest version (2.6)

I'm using a library that has a function that returns an instance of some class Engine.
I'd like to tack on some interfaces to Engine, so I subclass it class InterfacedEngine extends Engine implements AwesomeInterface. but when I change the code that uses the classes from this:
var engine:Engine = generateEngine();
to this: var interfacedEngine:InterfacedEngine = generateEngine();
It gives me a runtime error (elision mine):
TypeError: Error #1034: Type Coercion failed: cannot convert ...::Engine@1bc2bf11 to ....InterfacedEngine.
What about AS3 classes am I misunderstanding?

Say i have a movieclip named a_Mc ( ClassA ) I have a sub-movieclip named b_Mc ( ClassB )
CASE 1: Accessing the sub-movieclip b_Mc which is already present inside the a_Mc movieclip
( Since Flash IDE has "Automatic instance naming" OFF )
ClassA mentions the name of b_Mc as => var b_Mc:MovieClip;
NOTE HERE: That the variable name MUST BE same as the name of the instance on stage.
So i can access it as : trace( a_Mc.b_Mc);

I'd like to gain read only access to the following parameters of embedded Flash videos located on sites that I do not own through my own custom browser extension/add-on:
Time location of playback head (so I can display the current time in the browser extension via HTML5/JavaScript) Frames (so I can make capture them to an image file, save it and display image in browser extension) Original Dimensions in pixels (so I can display the original video dimensions via JS/HTML5 in browser extension)
Is this possible by using Javascript and HTML5 from a browser extension?
Would I have to use something like the SWFObject Javascript API [URL]

Cen i communicate to FMS from browser not with swf. For example - by javascript from user side or by C# from IIS server side.
I need to built a live chat application where the swf only get the live stream and show it to the user but all the other logic code that communicate to FMS will be not in the swf and not in some *.exe file.
I need this because this live chat appliction will have to work on apple ipad and iphone soon when FMS will be able to stream to those devices and i will have to abandon the swf anyway.

I have a BUNCH of bumpers of four types bounceUp, bounceDown, bounceLeft, bounceRight. during a collision which you hit determines the bounce so they always do the same thing so here's my question.....can i just name every bounceUp instance the same thing and then just add that one instance name to the list the collision detector checks?
i just dont wanna go through and name a hundred each of bounceUp s and bounceDown s individually as the potential for screaming increases proportionally.......

You can upcast or downcast an instance (to a superclass or subclass) using this syntax:
var i:MyClass = MyClass(instance);
But what does the as keyword do?
var i:MyClass = (instance as MyClass);

I am wrapping my brain around OOP in AS2. I am making two posts on two different subjects. My question here is: when should I use local instance variables, and when should I attach new properties to the instance object? (Feel free to correct my terminology.) Let's say I have a class for a scrolling background, which scrolls when I mouse over its edge. I want to put these values somewhere:
1) How wide is the border in which a mouseOver makes it scroll? This is basically a semi-constant I set it up once and keep it the same, unless the user changes it in an options menu to make the border wider or narrower. Call this scrollBorderWidth.
2) How fast is the background scrolling now? I want to track this so I can smoothly change the scroll speed over several frames. This is often changed. Call this scrollSpeed.
It seems I have two ways I can store and access these values and darned if I know which is better practice. METHOD A: Make them local variables in the class, so the scrolling background instance has them as local vars. I set them up thusly:

I have a base class I've used on 6 different MC's. Then when I use these MC's my function runs an if statement to check which one to add.
if(id=design) var obj = new design();
if(id=team) var obj = new team();
I want to make it a bit more dynamic and use the id:String to evaluate which new instance to create.
ActionScript Code:
public function loadChapter(id:String):void {
var obj = new instance_of( id )();

I have a bunch of text boxes which are acting as labels on a diagram.The idea is all the labels are jumbled up to start with, and the user has to drag the labels to the correct place.So far, I have the labels, and they are dragable, but I want to be able to lock the label onto a specific area (I've called them crashzones) so that when the user drags the label onto the correct area, the label snaps into place.The 'crashzones' instance names, are indentical to the label instance names, with the exception that the 'crashzones' instance names have the letter 'z' at the begining.
On the dragStart event, something (maybe a string) would hold the instance name of the current label and add the letter 'z' to the beggining, so something like ... crashzone = "z" + label1;As there is an instance with the name "zlabel1", when the dragstop event starts, it'll do a 'hittestobject' on the instance "zlabel1".
I'm not entirely sure how to go about this.I've tried creating a string to hold the 'crashzone' name, but the hittestobject event doesnt work with strings i.e: hitTestObject(stringname);I've also tried with Sprite, but as the sprite technically already exists and has a name, I can't give the sprite any properties.

it seems that Flash was supposed to run in a sandbox in the browser. But, if Flash can get data from a remote server, can it similarly get data from localhost IP on the same machine? In other words, can I use a Windows app that provides a TCP socket on localhost to feed data into a Flash app?the answer is yes at least for the case of an SWF file hosted in the file system, URL...(turns out the localhost access error can be fixed if you add the SWF app to some security whitelist). Still wondering if this can also be done for SWF apps hosted on the network.

I have to admit I pretty much ran away from Flash when AS2 came along and only used it for animation purposes over the last 5 years.So I'm having a major crash course in AS3 in Flash CS3 and I'm not enjoying it one bit. I'm getting maybe 10mins of finished work per hour as I try to figure out the limits and rules of AS3. Quite often it seems that AS3 simply can't do what I want it to. Anyway: Characterchecks.as is the main class and it loads a bunch of XML into four arrays. The file starts like this:[code]If I trace the value of, say, cc._Categories from the main FLA, it's empty. I'm guessing that the next line of AS in the main FLA doesn't wait for the previously called function to complete? (This may tie in to my next problem)My next step is that I want to display various things based on the data in the array. I have another class, Display.as which will hold all the functions to create the items on display. I thought it would be best for these to be a separate object. I wonder if I'm right?
So I declare an instance of Characterchecks in the main FLA and call it cc, and then run the functions to populate the arrays... Now I create an instance of Display and call it cd. How can I get functions in cd to see the values of the variables in cc? And if the main timeline can't tell that the functions aren't finished filling the arrays, how is cd supposed to know?I might be asking dumb questions, or maybe I'm doing things ***-backwards, I don't know. I'd appreciate any help, I really would. This whole thing has me at the end of my tether... being the most technically advanced person in my circle of co-workers and web design friends means I have no-one to explain why things need to be done a certain way or what the best way is.

Does anyone know how to get the width and height in ActionScript for a Flex application running inside the flash player in the web browser.
e.g. In the web browser I can use the tag to embed a Flex application (as a .swf). To the embed tag, I can provide the dimensions. I would like to get these dimensions inside the flex application action script.

I've published this document to a .swf. (Here's the .fla and .swf)In an AS3 Flash Builder project I load the swf with a Loader, then trace everything on it's display list with this function:

I have 2 copys of the same Movieclip on the timeline and I need them both to do the exact same thing, so I figured I'd give them the same instance name.
I have an event listener on the stage that listens for a mouse click and then checks what has been clicked usiing a switch statment, but the switch statment only picks up one instance of the movieclip, the other one comes up as the default.
Mainly what i'm asking is, is it possible to have to movieclips on the timeline with the same instance name?
public function Main() {
stage.addEventListener(MouseEvent.CLICK, doStuff);
}
public function doStuff(e:MouseEvent):void {
