Update the Text property in other containers

Calling all Flexpertz!

Hi, I'm trying to update a text property of the textarea with ActionScript that I've nested inside a vbox, within a Panel, inside a canvas.  When debugging, I noticed that the textarea object is null if its nested in other containers.  But if I allow it to be outside, I can put the text very well.

TypeError: Error #1009: cannot access a property or method of a null object reference.

Any ideas?

You want creationPolicy = "all", although its use is considered as anti-corporate good practices. Best practices has you the initialization of the components needed on creationComplete for the TabNavigator, but which can be annoying.

If this post answers your question or assistance, please mark it as such.

  • Reoading updated the text (from web) file

    I have a project that captures the text from a text file I have on my server. The code I use is at the bottom of this post...

    I have an empty cast member called "ClientListImport" and the script works great! - but the problem I have is when I update the text on the server (via a PHP script), the project manager does not update unless I left the projector and the re-launch. I tried to re - run the importFileInto script in the projector, but it won't pull in the new values.

    It's almost as if the text file is cached, or re - run the command is simply ignored for some reason any. How can I get Director to import the text updated on my server? I have to purge the first original text file? The code can be run one time?

    Any help would be appreciated.
    Thank you!
    ------

    Here is the code I use to insert the text file in my "ClientListImport": cast member

    > tempURL = getNetText (" http://www.MYWEBSITE.com/ClientListImport.txt")

    New: you need to add a fake query string so that the Director does not use
    a version cached

    netID = getNetText (" http://www.MYWEBSITE.com/ClientListImport.txt?id=" &)
    the milliseconds)

    > If netDone (netID) then
    > member("ClientListImport").text = netTextResult (netID)
    > end if

    Be aware that you must run a loop on a frame netDone expects to return
    Property to TRUE before accessing the netTextResult(). It is possible it is a 'failure '.
    for you because you jump right in front of the netDone because netTextResult is
    SET TO FALSE.

    -script #movie:
    global gNetID

    on prepareMovie
    tURL = "" http://www.MYWEBSITE.com/ClientListImport.txt?id= " "
    tURL = tURL & string (milliseconds)
    gNetID = getNetText (tURL)
    end

    on enterFrame
    If netDone (gNetID) then
    If netError (gNetID) = 'OK' then
    Member ("ClientListImport"). Text = netTextResult (gNetID)
    -spread regardless of other changes are necessary

  • Update the text in a button?

    Hello

    Live Help update the text to the button.

    I am working mainly on the timeline. I created a button symbol and added a field dynamic text instead, courses etc. keyframes. I gave the btn_text var and instance name text field.

    In the main timeline, I added the button 8 times and name each button a different instance. For example, the first button I gave an instance of contact_btn.

    In actionscript, I can add the onRelease listener using:

    floors_btn.onRelease = function() {}
    trace ("clicked floors");
    floors_btn.btn_text. Text = "floors";
    }

    Track works very well, but the text does not pass on the ground, I tried this a few different ways and I can't seem to change the text from outside the key.

    Any help in doing this would be great.
    Anthony

    make a single textfield in the button that spans all States, you try to load in a field that is not persistent. either that or change the buttons in movieclip buttons and use the same principle.

  • Update the text of the label on a XControl via a property

    Hi all

    I write various programs to help with the debugging of embedded systems. I often need to convert a value to byte into pieces and then show which of these bits are true/false. This is easily done by using the convert-bool-Bay VI. However, I would like to create a control that will allow me to display a name for each field of bits - a bit like the way records are described in the data sheets. The control must be a bunch of buttons, and then I can show the bits are true/false, and use the label of the button to hold the name of bit field.

    I went from one way to the creation of this feature in an XControl as this seemed the best. My group of updates to Boolean values correctly according to the value of byte brought into control. However, I use a property to set the Boolean control label text (names of bit fields). My debugging shows that the text is assigned to the label of the control, but the control panel never changes. I tried synchronous updates, and by forcing a new drawing of the Panel using DeferPanelUpdates does not.

    I would be grateful for any help on this - VI and XControl demonstrating the issue is attached.

    Thank you

    Ray

    Probably, because you try to change the text of the label.  Try to change the text of the legend...

  • update the text with xml, DDL data fields a selection of an identification number

    Hi guys,.

    It should be simple, but I can't seem to find a straight answer.  In short:

    The XML file contains the ID, name, location (so 3 extreme records in the example xml file)

    Form contains a dynamic drop-down list to allow the selection of ID and text fields to display the names of the partners and the location of this ID.  The setting of the drop-down list works fine, however I need to update the associated name and location if different from the other ID's fields are selected.  I guess I'll need some sort of event on the menu drop down update other fields with the name and location of the selected ID, but I don't know enough to have a stab at him.

    Please, please, please help, Im starting to pull my hair.

    James.

    Sorry, looking at him again I could have given a better description of what is happening.

    Have a look at this sample https://acrobat.com/#d=NO5o6NhPTQgSYu3SVoN7rQ and data to go with her https://acrobat.com/#d=jN * pRT4uGg05VU * sGWvjcA

    The thing I should have said and I guess that's your problem is the the Data property, I used in $data. Data.resolveNode (...) must match the item parent of the element of your event if xml looks like

    1

    name 1

    Location1

    It should be $data.events.resolveNode (...)

    Maybe I should have used "itemGroup var = $data.resolveNode ("events.event.» (()_eventId.value_===_«_«_+_xfa.event.change+_»_») "); "in this case, but I try and do the resolveNode go as low as possible.

  • Why is my new iPad Pro so more time to alert me on the texts then my other devices?

    I recently bought an iPad Pro 9.7 inches and looks like a backup and restore of my iPad 2. I have also an iPhone 4S and an iPad 2. I noticed it takes about 30 seconds for my iPad Pro to get them then my other device. I checked all my settings and reset the iPad and it still does not seem a job quicker. receive calls via my iPhone was also not working (after checking all settings). also have had problems with the sending of sms messages from my iPad. Thanks for any help.

    As you know the texts SMS are sent on the portion of cellular signal and are conveyed by the mobile phone service provider. The fact that it affects your phone calls and other messages on other devices - makes me want to suggest that you can be better to talk about this with your carrier

    Also given that the SMS through the iPad is mediated through the service of text messaging on the phone via the continuity - I'd look for a carrier update see if available

  • Why is able to save and update the passwords for sites other than those of Blackboard FF?

    I am able to save and update passwords on other sites, but not on the Blackboard learn for my University. They force us to change our pw is from time to time, and I think I noticed it after that Blackboard did some updates to their site. It will always load autofill with my old account and password, but not update it. I deleted the password stored and tried to get FF to remember once again on my laptop, but it has not yet asked to save him. I'm guessing that there is a new code or a script for the journal in the procedure? Is there a manual way to enter and update the credentials stored?

    Hello, sites can specify that passwords should not be stored (however I do know that if this is the case on the page you are having problems with, since you did not specify which University it affects). as a way to get around this, you can use an addon like this: https://addons.mozilla.org/firefox/addon/remember-passwords

  • Update the text file app/native/assets/data/in the workspace?

    I'm having a problem with updting a compressed file that is updated via a Web service.

    It is pretty simple what I'm doing. first wait for the answer

    QNetworkReply * response = qobject_cast(sender());

    check the data, etc.

    location of the file is "app/native/assets/data/somefilename.txt".

    QFile file (type);
    If (file.exists ()) {}

    leader. Open(QIODevice::WriteOnly |) QIODevice::Text);
    QTextStream out (&file);)
    off<>

    leader. Close();

    }

    It works fine on my local machine when I run it on my Z30 by momentics.

    But once I have add to my BES server and pull down on my workspace, the file is not updated. I can see the file updated in the application is correct the only thing is that the file not updated text.  From what I see the "app/native/assets/data / ' is read-only.

    My question is how update you text files that were packaged in the instalation of the app "app/native/assets/data / '?

    Thanks in advance

    It is not possible, assets / is read only when the application is deployed to the device, it is only readwrite on Simulator. data / folder can be used instead.

    Optionally, the file may initially active resident / and can be manually copied to data / on the first start of the application. After that it can be updated in the data / folder.

  • Access the Text property in the class

    I have problems to access the text fields .text property in my object. When I try to refer to the text box outside the service to create the text field, I get "1120: access of undefined property titleField.» Any idea is appreciated. Thank you!

    You have titleField declared as a variable for instance apart from this feature. (I think.) If this variable exists in your function addTitle. When it comes to your setPanelTitle that you can't simply make reference to the instance that you created earlier.

    So I think you could declare titleField as an instance variable.

    Or, in your setPanelTitle, you can use one of the functions getChildByName. I have not used enough AS3 it know right on top of my head, but since you have given a name - which is be the same as the name of the variable you used - you can find it by name later.

  • Set the text property of textbox.

    I know it's a very basic question, but I have little code here I tried to understand why it will work for about 3 hours.

    I have a button that you click when you want to send a message. I have also a keyboard shortcut for the Enter key to send the message. These two options, go to the same function.

    public void onKey(event:KeyboardEvent):void {}
    If (event.keyCode == 13) {}
    onChatSend();
    }
    }

    the button goes to onChatSend(); also

    public function onChatSend (): void
    {
    If (chatMsg.text! = "") {}
    if(infoPanel.Visible == false) {}
    sendStream.send ("onTextRecieve", chatMsg.text);
    chatMsg.text = "";
    }
    }
    }

    application.addEventListener (KeyboardEvent.KEY_DOWN, onKey);

    AH-AH! Switch the KeyboardEvent KeyboardEvent. KEY_UP

    I think that the value of chatMsg is overridden by the events of the text component. You want to leave the text component finished processing the ENTER key you are trying to edit its text value.

  • Do not update the content property object loader

    I have a SWF file on a server, it's a very simple animation.

    I have a SWF file on a different server, it loads the first SWF.  Here is my code base:

    Security.allowDomain ("my.central.server.com");
    var loader: Loader = new Loader(); allows you to load external SWF.
    var mcExternal:MovieClip; used to store the loaded SWF file.
    Loader.Load (new URLRequest ("http://my.central.server.com/data/FSC_Test_Automation/called.swf"));
    loader.contentLoaderInfo.addEventListener (Event.COMPLETE, swfLoaded);
    function swfLoaded(e:Event):void {}
    mcExternal = loader.getChildAt (0) as MovieClip;
    this.addChild (mcExternal);
    mcExternal.play ();
    }

    Everything works perfectly except in one case.  I use Questionmark Perception to deliver quotas online.  When the Flash containing the code above is provided as part of an assessment, the "mcExternal.play ()" does not work because mcExternal is null.  mcExternal is set to null because loader.getChildAt (0) is set to null (I also tried loader.content and loader.contentLoaderInfo.content).

    All the events fire properly.  I can even see the loaded SWF file.  The problem is that I can't start playing because I can't get a reference to it.

    My question: what is - which would allow to load external SWF file but not assign it to the content property of the loader object?

    the swf load needs the method, (allowDomain() or allowInsecureDomain()).

    Hi Mike,.

    I think you might find Anthony Action dynamic Sample Application very useful: http://apex.oracle.com/pls/otn/f?p=39830:32. If you connect to the application, you will find a link to download it, then you can take a look at how each of the samples have been implemented. The example of ' Set Value (SQL) "would be of particular interest in this case.
