Target movieclip from an AS3 class file - remove/add Child
Halo.
I have a very simple question (for those who use external class files).
Assuming that I have a MovieClip manually added to Stage and I want to access it from inside my class definiton.
So the code would be:
MovieClip(root).MyMovieClip
But I can't figure out how to use remove/add Child in that kind of situation.
I will appreciate any advice.
Thanks
if you can reference using that, you can remove using:
MovieClip(root).MyMovieClip.parent.removeChild(MovieClip(root).MyMovieClip);
and you can add to any displayobjectcontainer.

Web dynpro dc compoent controller method call from Java dc class file
Hi All,
Is it possible to call a wd java component controller method from a java dc class file?
I have declared wd java dc as used dc in java dc.Any poiters for the same would be really helpful.
Thanks in Advance.
regards
Radhika KuthialaHi,
short answer: No.
1. using WD references outside of WD DCs is unsupported and will at least show a warning when you try to deploy. Correct usage of runtime dependencies is not predictable.
2. WebDynpro Controllers have a lifecycle that is controlled by the Framework. Even if you manage to initialize a Controller via "new" and use a method, the Controller will never have all the state-information it contains when started regualary. (think of mapped context, context attributes in general, code called in wdInit ...) I would suppose it is possible to implement a runnable low-profile example that still works, but as soon as you try to use "higher" concepts of WD (which would be the only reason to use a WD Component Controller at all), you will definitely fail.
3. Think of it as calling EJBs Session Beans via "new", but more complex.
hope that helps

How do I alter the bytes of a Class file to add calls to the methods?
If i had the bytes of a class file, and I wanted to alter the bytes that constitute each method for the class so that it included a call to the security manager, how would i do it?
1. How would I know which bytes were the opening of a method?
2. how would I know what the name of the method is?
3. How would I create bytes for something like:
SecurityManager sm = System.getSecurityManager().checkPermission(thismeth, subject);
4. I assume that if by some miracle I can do the above, then all I have to do is call defineClass(...) in ClassLoader and send it the new bytes, right?
Thanks to all!OK, if it will help anyone get me the answers here, I found a class on the internet that can read a class file and tell you where in the bytes a method occurs and what its name is, and how long it is. What I need now is how to convert a call into the correct manner of bytes.
For example, so I could add the bytes that would do:
System.out.println("Added!");

/* This Java application analyzes the entries in the constant pool and locates

Getting file from directory where class files are
hi i want to load a properties file from the directory where my java program is (the class/jar files)
somebody told me that i could use System.getProperty("user.dir"); but it would only work under windows; under linux it points elsewhere.
how can i determine the directory where my program lies? sounds easy but i failed :(why to hell put it in the classpath? Because that way you don't have to ask the user where the hell he put the file.
and if i would do so the next question: how can my
program modify the classpath?It can't. And it doesn't need to.
isn't there another way to determine the directory
where the app is started from???If you mean the current, or working, directory, then yes there are several ways to determine that. But that directory need not be where the classes are actually stored. In fact the current directory doesn't even have to be in the classpath.
Now, here's the best way to deal with properties files. (IMHO of course.) Put them in the classpath, in the same directory or jar file as your classes. Then to create a Properties object and load it from your properties file named e.g. "default.properties" you do this:Properties props = new Properties();
props.load(this.getClass().getResourceAsStream("/default.properties")); -
How to dispatch events from custom AS3 classes to MXML
Hello,
I introduce some custom classes inside my SCRIPT tag in MXML.
These classes should dispatch custom Events (or any events for that
matter) and the listeners should be defined inside the SCRIPT tag.
In the custom class I have:
quote:
dispatchEvent(new Event("customEvent"));
And inside the script tag:
quote:
addEventListener("customEvent", testListener);
quote:
public function testListener(evt:Event):void{
Alert("Event fired successfully.");
However, this event is not handled in the listener (the alert
is not shown). What could be wrong?<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"

addEventListener("customEvent", testListener);
dispatchEvent(new Event("customEvent"));
private function testListener(evt:Event):void{
Alert.show("Event fired successfully.");
Do like this
Alert is the Class Object. This is not the Function. -

AS3.0: Can't add child and access subchildren timelines?
I have the following code:

//myParent.circ.width=300;
If I take
//myParent.rects.width=200;
//myParent.circ.width=300;
and remove the comments, the file breaks and no Movie Clips appear on the stage. Does this have to do with casting the Children as Movie Clips, which I may not have done here?No error codes Ned, it just adds the Child at the last frame in the timeline which happens to be frame 60 (I have a
n animation in the y direction just for kicks to see if I can get the animation to play and have the object move down

How to create empty text file on target system for empty source text file
Hi All,
I have an issue in handling empty file in the Text (FCC) to Text (FCC) file scenario. Interface picks text file and delivers on target system as text file. I have used FCC in both sender and receiver CCs.
Interface is working fine if the source file is not empty. If the source text file is empty (zero Bytes), interface has to delivery an empty text file on target system. I have setup empty file handling options correctly on both CCs.
But when I tried with an empty file I am getting the error message 'Parsing an empty source. Root element expected!'.
Could you please suggest me what I need to do to create an empty text file on target system from empty source text file?
Thanks in Advance....

the problem is that when there is an empty file there is no XML for parsing available. Hence in case you are using a mapping it will fail.
What ideally you should do is to have a module that will check if the file is empty and if so write out an XML as you want with no values in the content/fields.
Or the next choice would be to have a java mapping to handle this requirement. I guess that on an empty file the java mapping will go to an exception which you can handle to write out your logic/processing -
How to run several class files at the same time
I have four class files, there's: cvnt1.class,cvnt2.class,cvnt3.class and cvnt4.class.
I want to know how to write application for running all of those files together. thanks!Your question is still unclear - do you want to access code from those class files (just add all of them to classpath) or do you want to create number of threads or number of processes (one per class) and start code from each class simultaneously or something else?

Where to place an xml file that is read by java class file dir structure
Hello all,
I have an xml file that I am using in lieu of a database to track conference rooms . This is a small file. I need to read this file from my java class file which is used by a jsp. Currently I have an absolute path C://logger/conference.xml. All works fine but I need to deploy to a different machine soon and so I need to place this file somewhere in the project directory structure (created by netbeans) so that it will be included in the war file and can be read by the java class file.
Also what would be the relative path to this suggested directory.

TypeError: Error #1006 - Removing MovieClip from the stage
I have a movie clip that is called to the stage and once the movieclip is finished it calls a function that removes it from the stage. The code works but I get an error message about 4 seconds after the movie clip ends.
Here’s the error message:
TypeError: Error #1006: exitWordMicroscopic is not a function.
at ASvocabulary_microscopic/frame110()[ASvocabulary_microscopic::frame110:1]
Here’s the stage code:
//************************Removes the movieclip from the stage and enables the button.*************************
function exitWordMicroscopic():void
bnt_vocab_microscopic.mouseEnabled = true;
removeChild(word_Microscopic);
//******************************Stage buttons**************************************
stage.addEventListener(MouseEvent.MOUSE_DOWN, goButtonsHomeRead_1);
function goButtonsHomeRead_1(event:MouseEvent):void
//Vocabulary buttons
if (event.target == bnt_vocab_microscopic)
bnt_vocab_microscopic.mouseEnabled = false;
SoundMixer.stopAll();
addChild(word_Microscopic);
word_Microscopic.x = 47;
word_Microscopic.y = 120;
Here’s the code inside the movie clip. This is what the error message is referring to:
//****************** Calls function to remove itself from the stage****************************
Object(parent).exitWordMicroscopic();
What am I doing wrong?Here' how the code looks now:
Objective: To remove the current movieclip while it's playing so that it does not show on the next (or previous) frame.
Here’s the stage code:
var word_Microscopic:ASvocabulary_microscopic = new ASvocabulary_microscopic();
//Removes the movieclip from the stage and enables the button.
function exitWordMicroscopic():void
bnt_vocab_microscopic.mouseEnabled = true;
removeChild(word_Microscopic);
//******************************Stage buttons**************************************
stage.addEventListener(MouseEvent.MOUSE_DOWN, goButtonsHomeRead_1);
function goButtonsHomeRead_1(event:MouseEvent):void
//Vocabulary buttons
if (event.target == bnt_vocab_microscopic)
SoundMixer.stopAll();
bnt_vocab_microscopic.mouseEnabled = false;
addChild(word_Microscopic);
word_Microscopic.x = 47;
word_Microscopic.y = 120;
word_Microscopic.play();
//This button takes the user to the Main Screen
if (event.target == bnt_ReadGoHome_1)
// exitWordMicroscopic(); [If I use this function I get this error ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.]
SoundMixer.stopAll();
gotoAndPlay("1","Main");
stage.removeEventListener(MouseEvent.MOUSE_DOWN, goButtonsHomeRead_1);
//This takes the user to the next frame.
if (event.target == GoNext_1)
SoundMixer.stopAll();
gotoAndPlay("2");
stage.removeEventListener(MouseEvent.MOUSE_DOWN, goButtonsHomeRead_1);
Here’s the code inside the movie clip.
//****************** Calls function to remove itself from the stage****************************
Object(parent).exitWordMicroscopic(); -
I can't seem to remove / unload the external swf files e.g when the carousel.swf (portfolio) is displayed and I press the about button the about content is overlapping the carousel (portfolio) . How can I remove / unload an external swf file from the main flash file and load a new swf file, while at the same time removing garbage collection from memory?
This is the error message(s) I am receiving: "TypeError: Error #2007: Parameter child must be non-null.

Thank you for the helpful advice. I made the changes as you suggested but I am receiving a #1009 error message even though my site is working the way I wan it to work. I would still like to fix the errors so that my site runs and error free. This is the error I am receiving:
"TypeError: Error #1009: Cannot access a property or method of a null object reference."
I'm sure this is not the best method to unload loaders and I am guessing this is why I am receiving the following error message.
loader.unload();
loader2.unload();
loader3.unload();
I also tried creating a function to unload the loader but received the same error message and my portfolio swf was not showing at all.
function killLoad():void{
try { loader.close(); loader2.close; loader3.close;} catch (e:*) {}
loader.unload(); loader2.unload(); loader3.unload();
I have a question regarding suggestion you made to set Mouse Event to "null". What does this do setting the MouseEvent do exactly? Also, since I've set the MouseEvent to null do I also have to set the loader to null? e.g.
---- Here is my updated code ----
// variable for external loaders
var loader:Loader;
var loader1:Loader;
var loader2:Loader;
var loader3:Loader;
// makes borders resize with browser size
function resizeHandler(event:Event):void {
// resizes portfolio page to center
loader.x = (stage.stageWidth - loader.width) * .5;
loader.y = (stage.stageHeight - loader.height) * .5;
// resizes about page to center
loader3.x = (stage.stageWidth - 482) * .5 - 260;
loader3.y = (stage.stageHeight - 492) * .5 - 140;
//adds gallery.swf to stage at begining of moviie
Down();
//PORTFOLIO BUTTON
//adds eventlistner so that gallery.swf can be loaded
MovieClip(root).nav.portfolio.addEventListener(MouseEvent.MOUSE_DOWN, Down, false, 0, true);
function Down(event:MouseEvent = null):void {
// re adds listener for contact.swf and about.swf

MovieClip(root).nav.about.addEventListener(MouseEvent.MOUSE_DOWN, Down3, false, 0, true);
//unloads gallery.swf from enter frame if users presses portfolio button in nav

trace(error);
this.addChild(loader);
loader.x = (stage.stageWidth - 739) * .5;

Call function in main timeline from class file
Hi all, How can a function in main timeline be called from class file?
Hi all, How can a function in main timeline be called from class file?
You can, but you really shouldn't.
Classes shouldn't "talk" to the outside directly.
Use Event dispatching to get things done.
"root" (i just threw up by just typing that word) should be avoided at all cost, especially in AS3.
