• How to pass a variable between classes?

  Hello

  I created a class .as MovieClip to a MovieClip that contains 7 buttons. I use a table of these buttons and an array of labels of image on the timeline of the MovieClip parent to navigate in the labels.

  ...
  
  private function clickHandler(event:MouseEvent):void 
          {
  //Sets the current button listed in the button array    
   currentButton = MovieClip(event.currentTarget);
              index = buttonArray.indexOf(currentButton);
          
  //Uses the index variable to find the corresponding frame label from the label array            
  MovieClip(root).gotoAndStop(labelArray[index]);
          }
  
  ...
  

  This works perfectly.

  Now I have another .as MovieClip class, I created a simple MP3 player MovieClip. I'm pulling in a XML data of each mp3, including the URL, etc... All works perfectly.

  I'm trying to use the variable "index" of the class Nav.as in the class AudioPlayer.as to play the corresponding number of the song. By calling "playSong (index);

  "playSong (index);" works in a test file, when I tested the navigation tables and the corresponding number xml concept. I need to shoot the variable 'index' from Nav.as to AudioPlayer.as.

  ...
  
  private function playSong(mySong:Number):void 
          {            
              var myURL = my_songs[mySong].@URL;        
          
              if (my_channel) {
                  my_channel.stop();
              }
          
              my_sound = new Sound();
              my_sound.load(new URLRequest(myURL));
              my_channel = my_sound.play();
          }
  
  private function onPlay(e:MouseEvent):void {            
       playSong(index);
          }
  

  It works perfectly when tested. For example: "playSong (2)" or "playSong (5)" plays the song number correct.

  Thank you in advance!

  You should not have a currentIndex in each class, simply on the mother of the other 2 classes. When you say 'this.parent' you access the parent display object. This is where you want currentIndex to exist. If both classes are on the same display list then 'this.parent' will be the same parent and therefore the same variable.

  I didn't know what kind of display object container parent was (MovieClip, Sprite, etc.), so I've referenced it let go like: 'object (this.parent) .currentIndex '.

  Should be in NAV. As:

  Object (this.parent) .currentIndex = buttonArray.indexOf (currentButton);

  AudioPlayer.as should be read through:

  playSong (Object (this.parent) .currentIndex);

• pass variables between classes

  Hello! I'm new to flash actionscript and I make a small game right now. I thought to create separate movieclips for each level of play and their assigned separate classes is cleaner and easier to code.

  for example: -.

  level 1 - level1.as

  level 2 - level2.as

  Level3 - level3.as

  My problem is how to pass variables (such as health, score, etc.) to a higher level?

  Please help I'm stuck on this and I have searched a lot but couldn't get the right answer...

  Oh, and I use cs3 flash with actionscript 3.0

  I don't think you really understand what are classes and movieclips.

  MovieClips are display objects; your character, the enemy, elements, platforms< these="" will="" be="">

  Classes can be used to define new elements or extend those which already exist, such as an object or a MovieClip.

  For the purposes of making a game, I would separate levels of executives.

  do level 1 on a frame labeled "level 1".

  and level 2 on a frame labeled "level 2".

  variables will carry an image to the image.

  Use gotoAndStop (frame_label) to switch between levels

  * Make sure you use stop(); on the first image to prevent bike between the frames.

  * You can make the frames between each level that has the code "gotoAndStop(previous level)" to prevent people to hit 'play' on the swf file and the cycling through your levels.

  You can also search for SharedObjects as a method of storage of variables even after that the swf file is closed.

• Pass the URLLoader() variable between classes

  I have two classes. See below.

  What I want to do is quite simple, but I do not know how to do. I want the URLFactory for create table and store it in the variable 'dataArray' and use the table in the main class, by calling the GetList() class URLFactory. I have returns nothing... Please help

  Basically, I need to set a variable equal to URLLoader.data (var something: String = URLLoader.data) so I can use this variable in other classes. WHY ISN'T IT EASIER? Please, I beg you. A solution would be much appreciated.

  package classFiles
  {
  import flash.display.MovieClip;
  Import classFiles.URLFactory;
  
  SerializableAttribute public class MainClass extends MovieClip {}
  private var _UrlDriver:URLFactory;
  
  public void MainClass() {}
  _UrlDriver = new URLFactory ('url');
  var temp: Array = _UrlDriver.GetList ();
  
  }
  
  }
  
  }

  package classFiles
  {
  import flash.net.URLRequest;
  import flash.net.URLLoader;
  import flash.display.MovieClip;
  import flash.events.Event;
  import flash.sampler.Sample;
  
  SerializableAttribute public class extends MovieClip {} URLFactory
  
  private var loader: URLLoader;
  public var textData:String;
  public var dataArray:Array;
  
  public void URLFactory(url:String) {}
  textData = "";
  this.dataArray = new Array();
  loader = new URLLoader();
  loader.addEventListener (Event.COMPLETE, HandleComplete);
  Loader.Load (new URLRequest (url));
  
  Temp = CreateDataArray();
  }
  
  function HandleComplete(e:Event):void {}
  
  textData = loader.data;
  
  trace (dataArray);
  
  }
  
  function CreateDataArray (): void {}
  
  trace (dataArray);
  dataArray = textData.split ("\n");
  dataArray = textData.split('","');
  }
  
  public void GetList (): Array {}
  
  return dataArray.
  
  }
  }
  
  }

  Yes, the data loading is not instantaneous.  This is why you use a complete listener in your factory.

  Similarly, you must use a listener in your main class to check if the data is ready.

  p.s. Please check the useful/correct.

• Passing variables between classes

  I think I'm doing this more difficult than it really is. I would like to pass a variable of a class to another, once a file has been loaded. Currently I have a ListLoader that querys a PHP/mySQL which returns the XML of the class. I would like to create another class that processes this XML but I don't know how he pass only after it is loaded. It's getter/setter methods, or am I missing something really simple (or something else entirely)?
  
  Here are the two classes, with that I fight.
  
  

  Because the ListLoader makes the loading and the panels there appear, the panels need to know when the XML is available. If the panels accessed the magazine to the list, they either need to keep control if their XML is loaded, or subscribe to the magazine as a listener. It is better for the charger inform services' (the signs) when to use the XML.

  Better yet, if signs are essentially "views", take the treatment on the XML panels and give him the charger, then pass the XML transformed like a string or an object, or whether you need. In this way, the charger is the 'supply' and not the display panel, and the two don't get merged.

  The next step is to put in another class - essentially a data model that stores everything that has need of a Panel, so you might have different versions of panels, all you have access to the same data model. This class would then become the "model", and the Panel becomes the "viewer". (do a search for 'model view controller' - it's a basic OOP structure that goes a long way to help you think about OBJECT oriented programming, even if you do do not match exactly).

• To access the added Variables of Classes dynamically

  I'm not sure what the terminology is here, but it's what I do.

  I added the officials in the field via a loop and add to the screen

       // loop through all of the elements and setup the forums
          for (int i = 0; i < size; i++)
          {
              c_ForumSelect frm = new c_ForumSelect();
              frm = (c_ForumSelect) v_forums.elementAt(i);
              hfm_forumselect new_forum = new hfm_forumselect(frm);
              mainManager.add(new_forum);
          }
  

  I wrote the code that allows to "highlight" the domain manager.

  Is there a way to 'read' the Manager added variables?

  For example, if I had a Variable called 'ID' within the hfm_forumselect... How I acceding that when sound highlighted on the main screen of the user interface...?

  Who is?

  You can add them to a datastructure, a vector, for example. When you add them. Or add the database instead. or you can use the container Manager, navigation using getFieldCount and getField (index).

• How to access a global variable that is common between the different baskets project library

  My project consist of several libraries, after generation the library project packed for each library, I find it cannot share data in a global variable between different packaged project library file. For example: packed project library #1 contains VI variables global wirte 'position' and give it a value '400 '. Library #2 present another VI project try to read this global variable, but he gave reading of is NULL not "400". Why has this happened? Is it possible to solve, welcome any help, I wll appreciate for this!

  If you understand what is happening here...

  When you build a PPL, it takes in the .lvlib and also all the dependencies of the .lvlib.

  In your case, when you generate the Test Task.lvlib in a .lvlibp, she also pulls on a copy of the DataProcess.lvlib:GlobalsVariable.vi because it's addictive to read GlobalVar.vi.

  When your application runs, you end up with two copies of GlobalsVariable.vi in memory:

  DataProcess.lvlibp:GlobalsVariable.vi

  AND

  Test Task.lvlibp:: GlobalsVariable.vi (I don't know how PPLs namespace dependencies... If there is still the DataProcess.lvlibp)

  Because they are different screws (i.e. in a different namespace), they have their own memory and that's why you can't access the data.

  Your Test Task.lvlibp calls the version of GlobalsVariable.vi, he pulled the dependencies.

  To solve this problem - you must ensure that Task.lvlibp of Test calls the version of GlobalsVariable.vi of the DataProcess.lvlibp - you'll need to replace all instances with the version of the PPL. Of course, if you run DataProcess in the development environment, then it will always be bad namespaced, hence the suggestion to put your global variable VI in is own PPL that you then use in the process of data and Test tasks.

• to access public variables

  I have the code below. What I'm trying to do is to print the value of a public variable. I'm changing this public variable in the function that handles the result of the call to the remote object. The problem is that the value appears to change in function and no where else. Any ideas?
  
  
  <? XML version = "1.0" encoding = "utf-8"? >
  "" < mx:Application xmlns:mx = ' http://www.adobe.com/2006/mxml ' layout = "absolute" creationComplete = "load_list ()" >
  
  < mx:script >
  <! [CDATA]
  Import mx.controls.Alert;
  Import mx.collections.ArrayCollection;
  Import mx.rpc.events.ResultEvent;
  
  [Bindable]
  public var material1_ID: int;
  
  public function load_list (): void {}
  material1_ID = 0;
  }
  
  public function addRec (): void {}
  Alert.Show ("value before" + material1_ID.toString ());
  insertService.addMaterial('123'); This calls my webservice and returns a query
  Alert.Show ("value after" + material1_ID.toString ());
  }
  
  public void addMaterial(event:ResultEvent):void {}
  material1_ID = 9;
  }
  []] >
  < / mx:Script >
  
  < mx:RemoteObject
  ID = "insertService".
  destination = "ColdFusion".
  source = "insert".
  >
  < name mx:method = "addMaterial" result = "addMaterial (event)" > "
  < / mx:RemoteObject >
  
  < / mx:Application >
  

  This function in your code:
  public function addRec (): void {}
  Alert.Show ("value before" + material1_ID.toString ());
  insertService.addMaterial('123'); This calls my webservice and returns a query
  Alert.Show ("value after" + material1_ID.toString ());
  }

  Seems to me that you are the remote call and then waits for the next line to access the result. Flex does not work like that. Remote (including the HTTPService and WebService) calls are asynchronous. When you make the addMaterial call, demand goes out and the answer comes back 'later '. If just after this request will not be changed the value.

  If you print the value in the result handler, you will see that it will be changed.

• passing variables between the pop-up windows

  I'm moving one popup to the other variables. It works fien if I spend bvariable of main application as soon as I'm moving from variable popup to popup window it does not work here is what I am trying ro:

  That works fine

  hand. MXML

  private function launchMoreInfo (): void {}
  var win: view = PopUpManager.createPopUp (this, opinion, true) as point of view;
  //
  
  victory. AccountNum = list1.selectedItem.accountNum;
  Win.User = user;

  }

  But if I try to pass variables to the pop-up window, created from popup component, is not ' work

  View.MXML

  private function dsclientevents (): void {}
  var win2:view = PopUpManager.createPopUp (Thi, dsclienteventlog, true) like point of view;
  //
  
  win2. AccountNum = 'test ';

  }

  AccountNum is declared in dsclienteventlog.mxml

  Is it possible to pass variables between the pop-up windows?

  I would much apreciate your help

  Thank you

  Hi friend!

  I have faced this kind of problem and solved using 'Public static var '.

  Just, you declare a public static variable in your class Popup. Then you can directly set the value to this variable as,

  ClassName.StaticVariableName = value;

  In your case,.

  say PopUp2.mxml or PopUp2.as

  =======

  In the PopUp1 script:

  OnItemSelectionChange (event): void

  {

  PopUp2.m_iSelectedID = DatagridID.selectedItem.AccountID; It will change the value of this variable, even if the popup2 is open.

  your stuff here...

  }

  Try this, I hope this will help you.

  Thank you

• Passing variables between Forms

  Hi, I am currently working on a rock, paper, scissors project in my class oracle. I was wondering if an oracle form to pass variables between them. I created a login form, and I would once a user logs on to change his user name to one opponent text fields username in the form of game. Is it possible and in this case you may be able to show me an example of passing variables between Forms? Thank you

  You can use the Globals for this purpose. I mean in your login form when your will enter its correct information then and it press OK to the newspaper by so you can for example store their username in the GLOBAL variable

  :GLOBAL.USERNAME:=:FORM.FIELD_NAME;
  

  This global variable, you can access a form any of the current session.

• Public variables

  Could someone explain why it is considered 'bad form' to use public variables? I heard that they are a security risk, but I don't see why.

  If you talk about properties accessors (getters/setters) public vs, there are two schools of thought. One says that all property setters and getters corresponding. Other - only if additional functionality is required at the time of the getting or setting of values or a read/write access is limited.

  I belong to the second school.

  1. There is no doubt overload (size and performance wise) using accessors.

  2. strict data compiled and typing rules at the time eliminates the need for the accessors in validation of data type is.

  3. direct public properties can still be entartrées.

  School can't be good because it is too militant and limiting which (in my opinion and experience) is almost always a manifestation of fear instead of reason. Unless, of course, reason beyond doubt is provided that is not the case so far.

  Security problem in this context is completely unfounded. In my opinion, it's more about the excessive exaggeration and fear. Certainly, it is theoretically possible that in an attempt of language/framework to set the value of the variable with, say, integer data type to something not apparent is allowed and which can bombard the application but accessors do not prevent either.

• Access to a Java servlet class

  Can make a servlet running on the access of the server has a class defined on server B?
  More information:
  I am new to Java servlet programming and want to make sure that my web application is secure. I've implemented a Java class that returns information from the user (name, address, e-mail etc.) and I put in place of the jsp and servlet pages that access the class through a 'import my.class...» "for servlets and a ' @page import ="my.class... ". ' 'for the jsp. Pages jsp and servlets do session verification and authentication, but the class has nothing of all this - it's methods simply return the requested data. I don't want to put all the identifications in the class, but I want to make sure that there no way to other web servers out there on the internet could access this class in my web application. I don't think it is possible, but my fear is that some hacker out there could do it somehow remotely a @page import "my.class...". "on my Web server and then access my methods of the class? These web applications are run within a Glassfish 3.0 application server.
  
  Thank you!

  No.. Servlet running on a server can not access anything on server B that are not accessible via HTTP.
  Your class/jar files (and in fact anything under the WEB - INF directory) are not public.

  In fact, if you have WebApplicationA running on the server has WebApplicationB on the same server cannot access the WebApplicationA classes.

  You should not have problems of security in this regard.

• Passing variables between LabVIEW and TestStand

  Hello

  I'm just learning how to use TestStand and although there are a multitude of resources available, I always find me at a loss on how to pass variables between TS and LV, leaving me to think that there is one fundamental thing that I'm missing which is likely, given that I have a weeks experience with LabVIEW and a days of experience with TestStand.

  I took a glance to the example of 'Clusters' to the Code Modules in TestStand examples (I use TS 2016 if it matters) because I thought it would be quite ideal for what I hope. In this case, I hope to be able to pass a string (a file path) to LabVIEW and VI power take this string and use it as part of an order for the Exec.VI system.  Then, I would be able to pass strings back to TestStand to show the user if an error occurred, but I thought I should get the first part of work.

  I guess my question is what do I have to wait to see in clusters to the example of the Modules of Code? The Watch window displays all defined variables premise on which has the ContainerOut in the Variables pane, but I don't see any kind of update on facades (VI1.vi and VI2.vi) LabVIEW code. Should I be?

  I looked at a few other discussions of the forum here and here, as well as the document of the basis of knowledge here, but could not recreate their solutions. It seems that the connector pane would be a viable way to go, but I'm not sure on how we create and use effectively. According to this document , it makes it seem like it should be simple enough to makes these terminals, but I am still missing a key step. I was able to follow all the steps on the knowledge base document and run the sequence, but then had no idea if it worked or not; I have the report show me the values of the variables I put, but I have no idea whether or not he actually did anything with the LabVIEW VI, or how I could see that.

  Please let me know if you need further information or clarifaction everything I ask.

  Thank you for your time,

  If you want to enter values, you must create a vi for instance dialog box

  

  

  The OK button will allow new values to pass to the output terminals.

  A Cancel button will pass just the original through the output values without alteration. The VI will close when either the OK button or cancel were pressed.

• How to share a variable between the Mathscript Windows and a Mathscript node

  Hello

  I'm trying to share (just) a variable between the Mathscript Windows and a Mathscript node. I don't know why, but the use of the "global" Matlab function makes the mathscript node output formats change.

  I'm looking for a "Mathscript RT V9.0.1 module" as it may seem, there is. French technical support have some difficulty to find...

  Hi patrick33,.

  The code that you have attached should not report an error, so it seems that something has gone wrong with your installation of MathScript. My best guess is that it is the problem that is described in this knowledge base article. Your signature says that you use f3 patch, which is a good start. But the KB lists some other steps to take when you see errors about MathScript, impossible to compile. Can you try the procedure described in the article and let us know if that fixes the problem?

  Thank you
