• Not able to access the parent instance variable in outside of the methods in child

  Hello
  
  I don't get why I am not able to access the instance variable parent class apart from the example of the child class methods.
  

  class Parent
  {
       int a;
  }
  
  class Child extends Parent
  {
       a = 1; // Here i am getting a compilation error that Syntax error on token "a", VariableDeclaratorId expected after this token
       
       void someMethod()
       {
            a = 1;  // Here i am not getting any compilation error while accessing parent class variable
       }
  }

  Can someone let me know the exact reason for this, and what about the talks of error?
  
  Thank you

  You can only put assignments or expressions inside the methods, of the builders or the initializors class, or when you declare a variable.
  It has nothing to the child which stretches from Parent.

  class Parent {
      int a = 1;
  
      { a = 1; }
  
      public Parent() {
          a = 1;
      }
  
     public void method() {
         a = 1;
     }
  }
  

• How can a child navigatorContent access its parent?

  Hello

  Yes disatching an event is the way to go.  Here's the same example with this extra.

  Heres the Hotel component

  http://ns.Adobe.com/MXML/2009.

  xmlns:s = "library://ns.adobe.com/flex/spark".

  xmlns:MX = "library://ns.adobe.com/flex/halo" width = "400" height = "300" >

  protected function editButton_clickHandler(event:MouseEvent):void

  {

  dispatchEvent (new Event ('myButtonClick'));

  }

  ]]>

  [Event (name = "myButtonClick" type = "flash.events.Event")]

  You can see the sent button event handler and event called myButtonClick.  Notice the tag .  This tells the compiler to flex what we call this event and the type of event it is.  Otherwise said, he will expose in mxml and you can listen to it in the main file.

  This is the main file

  http://ns.Adobe.com/MXML/2009.

  xmlns:s = "library://ns.adobe.com/flex/spark".

  "xmlns:MX ="library://ns.adobe.com/flex/halo"minWidth ="1024"minHeight ="768"xmlns:local =" * ">

  protected function hotelcomp1_myClickHandler(event:Event):void

  {

  viewstack1. SelectedIndex = 0;

  }

  ]]>

  You can see here now in the viewstack in the mxml hotelComp that I have listed for the myButtonClick exactly as I would any other event and it called the hotel1Comp_myClickHandler that defines the index selected to 0.

  Hope that is kind to you.

• Hotmail 44 looks like your mother has not finished to set up parental controls for your account settings. Click "Access the parental control settings" to complete the process and access your account.

  I love how you get this error message, and then says that there is no support for this information.  You would think that if MS wrote this error message, they would assume someone would finally get it and need help.  Why I've bothered with this company I have no idea.

  All I want is to get my child HM account work. Ive clicked all this parental control I can find.  If this was the issue of the xbox, Id go immediately to gmail.

  Hello

  Had the same problem as the rest. All fixed now by:

  Abducted child security account for the family (Instructions in this thread)

  Account and went to outlook.com, let the updates.

  deleted the account from the local computer (Windows 8, users through the control panel * no * new user interface)

  Added and ensure that parental control is back on (it is by default)

  Can access the messages and followed the account. The account I had was old enough and not yet been used.

• Responsive HTML5 with mergedprojects, creates a hyperlink to a file in the project html parent to a child html file and it does not work! The child has with the parent TOC, but need to tie. Help, please!

  Hi group!

  I have a brilliant parent project that serves as a springboard for other projects. Users click a component of software they want and are redirected to a page with a list of all the documentation available for this component. Click on the name of a document and access - a lot of PDF files. BUT I also wish they were able to tie the online help for the component. After having read up on the link through / between projects, I knew that I needed to create a parent project (for the page intro and links brilliant) and projects for children (for software components).

  THEN

  I created a parent sensitive HTML5 project and the projects of two children. I compiled the parent to create mergedprojects files, and then open the projects children and collected to the appropriate mergedprojects folder. I then created a hyperlink to the file list html documentation in the project parent towards the child file software component html (output folder and start page [which is the same as the default theme]) and the link does not work! The child and its table of contents appears in the parent TOC so topics are here, but I can't link to them. If necessary, I can send screenshots.

  Where I am dorking this place?

  Thanks in advance for your time and help!

  Scottie 'needs help' gear

  What is your relationship like? And how did you create the link?

  A typical reactive merged help is structured as follows:

  index.htm (Master home page)

  mergedProjects

  childName

  index.htm (starting page for child)

  A child from the index.htm page link would look like this:... /... index.htm

  Kind regards

• To access the Parent DataProvider ItemRenderer?

  It is possible to access the individual ItemRenderer is based on a data item for the Parent control?

  For example, I use control CheckBoxList of Alex Harui who uses his CheckBoxRenderer.  I want to be able to all the checkboxes to enable or disable.  I have added a new toggleAll function to CheckBoxList, which looks like this:

  
  public virtual function toggleAll(selected:Boolean):void
  {
       if (dataProvider == null)
            return;
       
       for each (var item:Object in dataProvider)
       {
            if (item == null)
                 continue;
           
            item.selected = selected;
       }
  
       invalidateProperties();
  }
  

  However, I think I really need to access the itemRenderer and set selected here instead.

  Try this post:

• Accessing the parent Collection

  Y at - it a Navto command or otherwise (yet) to return to a collection of parent?

  I am familiar with the go to URL command to access the home collection: goto://ApplicationViewState/library

  However, we would really like to be able to "get out" of an item to the collection parent without having to call the built upwards in the navigation bar.  Any help?

  Not yet, but it's on our list to address in the near future. We really want to get this in, as well as a way to link directly to the collections.

• script of the child cannot reference the parent script

  Hello

  
  I define a variable (var photo1Show:Boolean = false ;) in the actionscript layer. I have a movie

  component of clip on the scene at this level. I double click on it to open it. This clip has a

  ActionScript layer were I put code "parent.photo1Show = true;". When I test the

  application, I get error:

  
  1119: access of property may be undefined photo1Show a static type reference

  Flash.Display:DisplayObjectContainer.

  
  What's wrong? Also, I'm using Flash CS4.

  
  King

  
  Code snippet
  -----------------------------------------------------------------------
  Parent frame: contains several layers. the two in question are the layer photo and action.

  layer action:

  PREV and next controls navigation botton

  var photo1Show:Boolean = false;
  var photo2Show:Boolean = false;
  var photo3Show:Boolean = false;
  var photo4Show:Boolean = false;
  var photo5Show:Boolean = false;

  Set your captions here
  var caption1 = 'model 1 Poise. "
  var caption2 = '2 model Poise. "
  var caption3 = '3 model Poise. "
  var caption4 = 'Poise of model 4 ';
  var caption5 = "model 5 poise."

  Define the name of the external folder of your photos in large and inches are in

  var galleryFolder:String = 'Nepalese ';

  Thumbs configuration, create instances of charger for every inch

  var pic1ldr:Loader = new Loader();

  ... The rest of the code in this layer is not important

  ------------------------------------------------------------------------------------------ --------

  photo layer:

  Contains the movie clip frame_mc on her diaper.

  I double click thre movie clip object. It contains several layers action, photo1 by photo5

  layers. PHOTO1 photo5 tape contains images, which, unlike keyframes.

  -------------------------------------------------------------

  layer action:

  Stop();
  parent.photo1Show = true;
  parent.photo2Show = false;
  parent.photo3Show = false;
  parent.photo4Show = false;
  parent.photo5Show = false;

  You must cast to the parent as a movieclip:

  MovieClip (parent) .photo1Show = true;

• How to access the parent container?

  I have the following code
  
  newButton = new Button();
  newButton.label = 'Submit ';
  newButton.id = "btn_" + arrPerformance.getItemAt (x) .fld_question_number;
  newButton.addEventListener ("click", saveAnswer);
  
  newRichTextEditor = new RichTextEditor();
  newRichTextEditor.id = "answer_" + arrPerformance.getItemAt (x) .fld_question_number;
  newVBox.addChild (newRichTextEditor);
  newRichTextEditor.toolbar.addChild (newButton);
  
  As you can see, I added a button to the toolbar of the rich text box control.
  
  The "saveAnswer" event listener saves the content of the rich on the db text control.
  
  But I can't understand how to reference the container of rich text.
  If I use event.target.parent it gives me only the toolbar!
  
  Also note that the form has several of them, thats why he is in the action script.
  So I need to be able to access the rich text box 'textarea' and id, so I can go to the SWC.
  
  Ken

  Thank you for that.

  I missed the controlbar, so I was a 'parent' call for short.

• Can someone point out code examples on how to access the windows registry?

  I'm new to the Acrobat SDK/Visual C++ and would like to know how to access the windows registry to view the identity of the current user of the reader.

  I know it's at the following registry location:

  HKEY_CURRENT_USER\Software\Adobe\Adobe Reader\9.0\Identity

  I don't know how to access programmatically by using Visual C++.

  Thank you

  Gregory

  There is nothing special a plugin regarding the registry - standard OS calls work fine.

• to access the audio data

  Hello!

  I want to detect the events in the audio and take some action defined for example one keyframe to another article.

  Specifically, I'm trying to count the number of vertices (as you would see at a glance Slate) in a period of time and get this as a numerical value that I can use in other calculations.

  There may be more such an event by video image however if ideally I need real audio sample data access.

  Is it possible to get the audio data as an array of values?

  It is not so difficult to find a leading edge on a certain amplitude and count that as an 'event', if you have the data.

  I can't find anything on audio in the script guide, unless an AVItem has audio or isEnabled.

  Alternatively, if this option is available in the Premier or hearing I'm happy to work there but they do not seem to support scripting at all!

  Anyone?

  Thank you!

  + Leo

  If you need to get down to the detail of sample auto, I think that you will need to go on the road to plugin. None of the plugins I've written have involved audio samples, but that the data may not be accessible after the SDK. Maybe this should be your next step.

• Is there a way to access the HTML data as you can do with XML data?

  I am new to AS3 and I'm trying to figure out how to access HTML as you can with the XML data?

  HTML isn't XML, nor is the DOM supported as JavaScript does, so you'll have to go with the typical string operations. If it's on a website, you can use JavaScript to make the analysis of DOM for you in HTML via AJAX loading and working back and forth between JS<->As.

  Otherwise the Interior HAVE only, Regular Expressions are most useful for this. The HTML code in a viable XML structure analysis may be possible when it is not applying the same syntax rules it and is of a dynamic nature. For example, it is perfectly valid to put the content in a page that is not nested inside a tag, for example

  some paragraph

  Some text let only locked in the body. You need detect possible syntactic questions and manage all of them. Channel ops are much easier.

  Any specific markup? you have trouble to detect/work?
