Something simple that I'm missing: switching XML text problem

I'm sure it's something simple I'm missing. I was looking at this code for some time now, I'm hoping that a fresh pair of eyes can help out me:

I have a title for my videos of xml that are loaded with the video of the scene. When you click on a thumbnail of the image of the video, what is supposed to happen is the title of the video could appear above of the new video and remove the previous title of the video. Instead, remains the previous title and the new title of stacks on top of the other.

Here are some of my code:

          //Process XML==================================================================================================================
          public function processXML(e:Event):void{
               var myXML:XML = new XML(e.target.data);

               thumb_width = myXML. @ THUMB_WIDTH;
               thumb_height = myXML. @ THUMB_HEIGHT;
               video_x = 200;
               video_y = -20;
               my_videos = myXML.VIDEO;
               my_total = my_videos.length();

               makeContainers();
               thumbs_x = thumb_container.x;
               thumbs_y = thumb_container.y - 20;
               callThumbs();
               makePlayer();
          }
          
          //Make Containers=================================================================================================================
          public function makeContainers():void{
               main_container = new Sprite();
               thumb_container = new MovieClip();
               addChild(main_container);
               titles = new Sprite();
               
               thumbs = new Sprite();
               thumbs.addEventListener(MouseEvent.CLICK, playVideo);
               thumbs.addEventListener(MouseEvent.MOUSE_OVER, onOver);
               thumbs.addEventListener(MouseEvent.MOUSE_OUT, onOut);
               thumbs.x = thumbs_x;
               thumbs.y = thumbs_y;
               thumbs.buttonMode = true;
               main_container.x = -10;
               main_container.y = -10;
               thumb_container.addChild(thumbs);
               main_container.addChild(thumb_container);
               main_container.addChild(titles);
               thumb_container.mask = thumbScroller.vThumbMask;
                              
               thumbScroller.next_btn.addEventListener(MouseEvent.MOUSE_DOWN, doAction);
               thumbScroller.previous_btn.addEventListener(MouseEvent.MOUSE_DOWN, doAction);               
               thumbScroller.next_btn.addEventListener(MouseEvent.MOUSE_UP, releaseButton);
               thumbScroller.previous_btn.addEventListener(MouseEvent.MOUSE_UP, releaseButton);
          }

     
          //Call Thumbs==================================================================================================================
          public function callThumbs():void{
               
               for (var i:Number = 0; i < my_total; i++)
               {
                    var thumb_url = my_videos[i].@THUMB;
                    var thumb_loader = new Loader();
                    thumb_loader.name = i;
                    thumb_loader.load(new URLRequest(thumb_url));
                    thumb_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, thumbLoaded);
                    thumb_loader.y = (thumb_height+10)*i;
               }
          }

          public function thumbLoaded(e:Event):void{
               var my_thumb:Loader = Loader(e.target.loader);
               thumbs.addChild(my_thumb);
          }
          
          
          //Make Player==================================================================================================================
          public function makePlayer():void{
               my_player = new FLVPlayback();
               my_player.skin = "SkinOverPlaySeekMute.swf";
               my_player.skinBackgroundColor = 0x70A16C;
               my_player.skinBackgroundAlpha = 0.5;
               my_player.skinAutoHide = true;

               my_player.x = video_x;
               my_player.y = video_y;
               my_player.width = 450;
               my_player.height = 338;

               main_container.addChild(my_player);
               my_player.source = my_videos[0]. @ URL;
          }
          
          //stop audio and video
          public function stopPlayer():void{
               my_player.stop();
          }
          
     
          //Thumbnail Functions-----------------------------------------------------------------------------------------------------------
          public function playVideo(e:MouseEvent):void{
               var video_url = my_videos[e.target.name]. @ URL;
               my_player.source = video_url;
               thumbs.addEventListener(MouseEvent.CLICK,getTitle);

          }

          public function getTitle(e:MouseEvent):void{
                    var thumb_title = my_videos[e.target.name].@TITLE;
                    var title_txt:TextField = new TextField();

                                 //THIS DOESN'T WORK. FOR SOME REASON IT DOESN'T SEEM TO EVER GET CALLED 
                    if(titles.contains(title_txt)){
                                     trace("remove previous title");
                         titles.removeChild(title_txt);
                    }
                    
                    var myFormat:TextFormat = new TextFormat();
                    myFormat.font = "Helvetica";
                    myFormat.color = 0x000000;
                    myFormat.size = 25;
                    title_txt.defaultTextFormat = myFormat;
                    
                    title_txt.text = thumb_title;
                    title_txt.y = video_y - 40;
                    title_txt.x = video_x + 50;
                    title_txt.width = thumb_width;
                    title_txt.height = thumb_height;
                    title_txt.wordWrap = true;
                    titles.addChild(title_txt);
          }


Also, for some reason, when the swf first loads, the title does not appear for the first thumbnail clicked but it starts to appear when you click a second thumbnail.
Any help will be very much appreciated!

The likely problem of lies between the following lines...

var title_txt:TextField = new TextField();

if (titles.contains (title_txt))

{

titles.removeChild (title_txt);

}

You just create an instance named title_txt.  So any reference to it thereafter is the newly created instance, no matter what that may already exist.

I have just to keep a textfield and replace what is in it.  But if you want to continue to create instances and accumulate them in memory, then probably just want to use something like...

if (titles.numChildren > 0)

{

titles.removeChildAt (0);

}

  • Selection of the menu XML text problem

    Hi all

    I built a video menu xml that displays a simple text of my XML document in a movieclip that is added to a sprite called btnContainer, the btnContainer is then added to the scene. Once these buttons are selected, they load the appropriate video. The problem I have is that I want the selected button to change color. There are three different XML files loaded according to 3 static buttons on the stage, that is to say 2009 / 2008 / 2007. By default the code 2009 XML file is loaded. My code works fine the first time that the script runs - when one of the XML buttons is selected it changes color and returns all other buttons to their default color - but when I click on the button 2008 or 2007 and load their XML files, and the buttons do not change their color. Then when I click on back button 2009 and 2009 XML load button changes color but the rest of the buttons do not change in their default state? My code is below

  • Pages won't open the files that I've updated 2 days ago missing index.xml extension?

    I've updated several documents marketing two days ago. When I saved the files, there was a pop-up notice that they have been saved as a newer version of the file as a result of the most recent update. Today, I went to a few final tweeks before loading the changes on my printer and files will not open. It is said that the error message "missing index.xml file. I just checked and downloaded/installed all the updates available and rebooted my macbook, but the files will still not open. PLEASE HELP ME TO RECOVER MY FILES!

    You have two versions of Pages on your Mac, probably the Pages ' 09 and 5.6.1 Pages.

    When you have clicked on your Pages ' 09 version previously opened in Pages 5, 6.1 and was converted into a format of Pages 5.6.1.

    When you double click on the document today you opened in Pages ' 09, who cannot open the format of Pages 5.6.1.

    To open the document in the correct application, right-click on the document and choose. Pages ' 09 has a bottle of blue ink icon, Pages 5 has a generic research paper Orange.

    If you want to convert your document to Pages ' 09, because it has over more than 100 features and is much more productive:

    Open the document in Pages 5.x > file > export > Pages ' 09

  • I must be missing something simple...

    I just started usng a new Epson R3000. Print letter size is no problem. However, I can't get it printed at 13 x 19. No matter what I do a 8.5x11 print (on a big, expensive piece of paper!). This happens with the driver set to "Super B", and also with a custom paper size, I created. The driver claims it will print to the appropriate size, but the output is 8.5 x 11.

    It's as if there is a kind of selection that replaces what I do in PS.

    Furthermore, I use PS CS 5.5, Mac Lion, printing via ethernet.

    What Miss me?

    I found it... Under management of the paper, there is a box that says 'fit to paper size' or something like that. I need to check that, even if the image was already on the right size. Without checking that the pilot decreased things down for a reason any.

    I try to run the security essentials, and he tells me that I'm missing msvcp90.dll. Same problem occurring with a real player has not re - install. How can I recover file?

    Hi BradleyMitchell,

    1. did you of recent changes on the computer?

    2 when was the last time it was working fine?

    3. what version of Real player installed on the computer?

    Msvcp90.dll error can be caused if the Visual C++ Library Runtime components are missing or corrupt on the computer.

    Method 1

    I suggest that scan you SFC on the computer that would be a system file corrupt on the computer search and replace.

    The analysis may take some time, so be patient. Windows allows to fix corrupt or missing files it finds. If the information of the installation CD is required to fix the problem, you may be asked to insert your Windows XP installation CD.

    If the previous step fails, then install the Package redistributable Microsoft Visual C++ 2008 and check if it helps.
