How to remove an Element that was added from code?

Hello,
I have a custom BorderContainer component with 2 labels and 1 image.
I added an instance of it to my application from code with addElement() and now I cannot make it disappear
I try:
    for (var i:int=0;i<numElements;i++){
     if (getElementAt(i) is Card){
      if ((getElementAt(i) as Card).name.substr(0,6)=="cMover"){
       removeElementAt(i);
It finds it because it gets to removeElementAt(i); but the component remains visible.
I also tried  removeElement(getElementAt(i)); no luck.
What am I doing wrong?
thanks
Gabor

You may have to call
invalidateDisplayList();
After you remove it.

  • How to remove a hotfix that was imported manually via the Microsoft Update Catalog

    Is there any way to remove a hotfix that was imported into SUP by manually importing it into WSUS from the update catalog?  I know making changes in WSUS that is used for SUP not advised but if I decline those updates will they get removed from the
    SUP catalog?

    Maybe. You are more or less entering uncharted territory -- certainly unsupported territory. Try it in your test environment.

  • How to remove an icon that was dragged onto Finder toolbar

    I'm sure this is a silly question, but I dragged an image file onto the Finder taskbar by accident, and can't see how to remove it.
    Can someone put me out of my misery?

    If you mean the toolbar at the top of the Finder window, you can command-drag it off.

  • How do I remove an application that was trashed from an external drive?

    I did a clean install of Snow Leopard and used Migration Assistant to restore my apps from my Time Machine backup.
    I also have a second external drive, and I had something on it called "iP100 series On-screen Manual". It's a manual for my printer that I didn't need anymore so I moved it to the trash.
    As soon as I did that, a little printer icon with a question mark appeared on ALL my Mac folders - even the ones on the external drives. When I move my curser over  the icon, it's identified as  "Trash of Seagate External Hard Drive>iP100 series On-screen Manual".
    I emptied the trash, thinking that the little icon would go away, but it was just replaced by a big question mark. Then if I click on the question mark, I get the message: "The item can't be found".
    I reinstalled the printer from a CD, and it put an alias on my desktop called "iP100 series On-screen Manual" which does open the on-screen manual, but when I try to find the original, it takes me to a file in the Applications Folder called "Contents8f.help" which also opens the on-screen manual, so it must be the original. I tried renaming the file to the same name as the alias. I tried trashing it. I tried trashing everything related to the printer and reinstalling again, but nothing has worked. The question marks remain!
    It seems that my Mac has a desperate need to find "Trash of Seagate External Hard Drive>iP100 series On-screen Manual" but the trash is empty and I have no idea where to find this item that  "can't be found".

    Thanks. I couldn't get the control-click to work, but I found that if I opened a folder and picked "Customize Tool Bar" from "View" in the Finder, I was able to drag the question mark out of the toolbar and onto the desktop where it "poofed' and disappeared. Doing this removed the question mark from the toolbar in all my folders.

    - Sometimes resetting the iPod works:
    Reset iPod touch:  Press and hold the On/Off Sleep/Wake button and the Home
    button at the same time for at least ten seconds, until the Apple logo appears.
    - Another solution that usually works is to download the app on your computer and sync.  However, since it was not downloaded under you account it may not work.
    - What should work wold be to restore you iPod from backup since your backup since the apps themselves are not in a backup.

    I would be glad for the opportunity to customize a Premiere Elements 12 answer to your Premiere Elements 12 issue.
    But, I want to make sure that we are together on the details. This is my understanding of what you have written. Please review and let me
    know if I am misinterpreting anything that you have written.
    You have a video created in Windows Movie Maker.
    How did you output the video from Windows Movie Maker...wmv or mp4, what was the frame size and frame rate of that export?
    Next you import that video into Premiere Elements 12 (can we assume that this is on Windows 7, 8, or 8.1 64 bit?)
    From what you wrote, you have applied a pan and zoom effect to your video in Premiere Elements.
    Now you go to export the Premiere Elements 12 Timeline content with your video with the pan and zoom applied.
    But, the pan and zoom effect is not seen in playback of the export.
    Is all of the above correct so far?
    If so....we are going to need some more details from you...
    a. What is the project preset that you or the project are setting to match the properties of the video coming from Movie maker? See Edit Menu/Project Settings/General and the readings for Editing Mode, Timebase, Frame Rate, and Pixel Aspect Ratio even if the fields look grayed out.
    b. Are you applying the pan and zoom effect with the Pan and Zoom Tool, fx Effects Presets, or keyframing the Scale (for Zoom) and
    Position (for Pan) in the Motion Panel expanded?
    c. What are you selecting as your export in Publish+Share/. Please give details...are you using default settings or customizing the export
    setting under the Advanced Button/Video Tab and Audio Tab of the preset selected?
    I am suspecting some sort of mismatch of your project settings or some problems with working with the Pan and Zoom tool. I need
    your answers to help me help you. If I have written anything that you do not understand, please let me know. I will re-write if necessary
    so that we are in sync to resolve the issue.
    Thanks.

  • How to remove the old email address that was hacked from my iCloud account when iCloud won't let me?

    How to remove the old email address that was hacked from my iCloud account when iCloud won't let me?
    Pretty much the the email that I used (but didn't verify) to create my iCloud account was hacked and now I can't remove it from my iCloud account due to the iCloud password also being changed by the same person and the fact I had "Find my iPhone" app on my phone also??? I had to change my iTunes email as well but that was far easier so yeah :S.
    Please help. I live in NZ, out in the country, so reception is rare and so is getting into the nearest town that has an Apple Store.
    Thanks

    If you truly change your existing Apple ID's email address to a new email address, follow these instructions: iOS 7: If you're asked for the password to your previous Apple ID when signing out of iCloud
    If you created a whole new Apple Account because you couldn't access the old one after being hacked, you will need to contact the Apple Account Security Team. Apple ID: Contacting Apple for help with Apple ID account security

  • How to remove preinstalled files of adobe photoshop from my mac mini so that i can install a new version of the same software.The previous version was removed using the app cleaner software.Could not continue installation bcoz of earlier files

    How to remove preinstalled files of adobe photoshop from my mac mini so that i can install a new version of the same software.The previous version was removed using the app cleaner software.Could not continue installation of the new version because of the existance of files from the previous version.plz help

    What "app cleaner software" ? I ask because installing Photoshop over a previous version has never been a problem. Perhaps your difficulty stems from another source, eg. "cleaner software" ?
    If you look in your hard drive, at the root level there is a Library. In there is a folder called Application Support, and in that you will find a folder called Adobe. Files from your previous version are there.
    However, I urge you to call Adobe support to make sure you are not doing anything that would mess up other Adobe applications.
