Right Click in the Frequency control and deselect Unit Label from Visible items.
Hz will disaapear.
Except that the numbers will still have a unit associated with them. If the user doesn't want a unit then they have to select the text and delete it, not just hide it.

Remove method of array

Implement the following method in the class Project 11 to return a new array that contains all the elements of the array a not in b.
Public static int [] remove (int[] a, int[] b)
For example, if the array a is {5,3,2,7,1} and the array b is {8,2,5} the remove method should return the array {3,7,1}.
Im having trouble getting it run correctly, and i think my problem is with the remove method that i made
//heres my code
public static void main(String[]args) {
int [] first = {2,5,4,1,9};
int [] second = {5,10,8,1};
int duplicate =0;
for (int i = 0; i < first.length; i++) {
               for (int j =0; j < second.length; j++){
                    if (first[i] == second[j])
                         duplicate++;
                    remove(first, second);
System.out.println(first);
public static int [] remove(int[] a, int []b){
for(int i = 0; i < a.length; i++) {
if(a[i] == b) {
int[] c = new int[a.length - 1];
return c;
return a;

Remove Entry from Array

Hi,just another question. Is it possible to remove an entry inside an Array without splitting up by using SubSet und with a combine after that? I found no function for that way...RegardsHenrik

The new LabVIEW 6i has a "Delete from Array" VI that will do this more
elegantly.

Removing Items From Array Collection

Hi. I have an array collection which is made up of items
defined in class PlayListEntry. I want to remove all the items that
have the value of property select set to false. This is what i have
come up with, it works fine, but only removes half the items at a
time. I think this is because when you remove and item with
removeitemat() it shifts the index of the items. How can i get
around this?
Code
private function removeitems():void{
for each (var ple:PlayListEntry in songCollection){
if (ple["select"] != true){
songCollection.removeItemAt(songCollection.getItemIndex(ple));
}

Here's a sample application I wrote that achieves what you're

Remove element from array

hi
if i have an array
eg
int[] array = {4,2,1,2,1};
how to i remove the index 2 from it and create a new array?
thanks

You can't remove the element--an array's size is fixed at creation.
If you want a new array, create a new one that's one element smaller, then use System.arrayCopy to copy the elements you want to keep.

Remove repetitions from array

I would like to know how to remove repeitions from a 1D array. For example, AAANNNNDDDDKLL to ANDKL.
Also, what if the array is not sorted?

Remove item from Array

Hi,
Can i remove a single item in my array or remove all elements???
Tnx all
Beck74

This is a quick way to remove an element. It avoids looping which avoids an ArrayIndexOutOfBounds check with every iteration. Also, arraycopy is native which means that it is very efficient and suitable for large arrays.
public class arraytest
    public static int[] remove(int _i, int[] _a)
     int[] b = new int[_a.length-1];
     System.arraycopy( _a, 0, b, 0, _i );
     System.arraycopy( _a, _i+1, b, _i, b.length-_i );
     return b;
    public static void main(String[] args)
     int[] a = {1, 2, 3, 4, 5};
     // remove element 3
     int[] b = remove(3, a);
     for( int i=0; i<b.length; i++ ) {
         System.out.println( b[i] );
}

Remove folders in array

Hello everyone,
I am currently troubleshooting the piece of code below. When I run this script, the second while loop is causing the script to break.
The first while loop figures out which items in my project is folderItems and put those in an array but it makes sure not to put folder called "Cleaning" in there by identifying it by its ID.
The second while loop runs through once and let's me, accurately, know how many folders is about to be deleted. It then deletes the first folder in the array, then gets rid of the first element in the array so the lenght of the array shrinks. The second time through the while loop, it again lets me know how many items remain to be deleted and then it breaks on "removeFolders[0].remove();".
Any ideas whats going on?
Cheers!
var j = 1;
var removeFolders = new Array();
while (j <= app.project.numItems) {
    //alert(app.project.numItems);
    if(app.project.item(j) instanceof FolderItem && app.project.item(j).id != cleaning.id) removeFolders.push(app.project.item(j));
    //if(app.project.item(j) instanceof FolderItem && app.project.item(j) != cleaning.id) removeFolders.push(app.project.item(j));
    ++j;
while (removeFolders.length != 0){
        alert("How many folders to be removed: " + removeFolders.length);
        removeFolders[0].remove();
        removeFolders.splice (0, 1);

Hello,
i just tried your code with a dummy project (10 folders with various names, some comps with some solids), got no error, it deleted all folders except the one called 'cleaning'.
What is your error message when the script breaks ?
You can try deleting last to first, it might change something although it's not clear why it would, it's essentially the same:
while (removeFolders.length)
    alert("How many folders to be removed: " + removeFolders.length);
    removeFolders.pop().remove();

Remove multiples from array

Hello,
I am trying to remove multiples of a fundamental frequency from an array of frequency points. One extra issue with this removal, is that the multiple of the fundamental frequency from the array may be within a range, like +/- 1k. Any help will be greatly appreciated.
Thanks,
hiNi.

Deactivate "insert element before / remove element" in array

Hello guys.
It is possible to deacitvate "insert element before / remove element" function appears after right-click on a array in the frontpanel?
"Description and Tip" should stay.
Thank you.
Alex
Solved!
Go to Solution.

You can customize the right-click shortcut menu to remove some application items and keep others:
Right-click on the array (and not on the array element!) in the front panel and select Advanced->Run-Time Shortcut Menu->Edit...
This brings up the Shortcut Menu Editor:
Change the drop-down control from "Default" to "Custom".
Select the "???" line in the tree control on the left.
on the right, change the Item Type from "User Item" to "Application Item -> Description and Tip..."
It will automatically fill in the corrent Name and Tag.
Save the rtm either into its own file or into the control.
LV will automatically handle application items in the control, no event case needed.
I sometimes find the "Copy entire menu" function of the shortcut menu pretty useful if I only want to disable a few items.

How to remove UNIT ERR from report

Hi,
When the report is executed, the columns and key figures (restricted, calculated) etc are displayed properly, but under every key figure column header there is a word "ERR" is displayed , please let me know how this can be removed from the report.
Thanks
Akila. R

Hi,
As suggested in the above threads either maintain the Units for the objects or try to remove the ERR message by using the function NODIM() for corresponding key figures.

Error #2025:The supplied DisplayObject must be a child of the caller - Removing Object from Array

Hi guys, I'm pretty new to as3 and I'm trying to make a game where the player supposedly clicks on the stage and 3 towers which I've spawned dynamically should shoot towards the area. Everything works in terms of tower rotation, etc, but the bullets will not be removed from the stage when I exit the level into another scene. The boundary checking is fine, too.
Here's a part of the code in the Main.as file.
private function clickTower1(e:MouseEvent):void
for each (var tower1:mcTower1 in tower1Array)
var newLaser1:mcLaser1 = new mcLaser1();
newLaser1.rotation = tower1.rotation;
newLaser1.x = tower1.x + Math.cos(newLaser1.rotation * Math.PI / 180) * 40;
newLaser1.y = tower1.y + Math.sin(newLaser1.rotation * Math.PI / 180) * 40;
newLaser1.addEventListener(Event.ENTER_FRAME, laser1Handler);
tower1BulletArray.push(newLaser1); stage.addChild(newLaser1);
private function laser1Handler(e:Event):void
//Make laser move in direction of turret.
var newLaser1:MovieClip = e.currentTarget as MovieClip;
newLaser1.x += Math.cos(newLaser1.rotation * Math.PI / 180) * laser1Speed;
newLaser1.y += Math.sin(newLaser1.rotation * Math.PI / 180) * laser1Speed;
//Boundary checking if (newLaser1.x < -50 || newLaser1.x > 800 || newLaser1.y > 600 || newLaser1.y < -50)
newLaser1.removeEventListener(Event.ENTER_FRAME, laser1Handler); stage.removeChild(newLaser1);
tower1BulletArray.splice(0, 1);
I have a function called exitLevel, which basically, as the name states, exits the level when a button is clicked. It worked perfectly before I started coding the bullets.
private function exitLevel(e:MouseEvent):void
stage.frameRate = 6;
gamePaused = false;
clearLevel();
gotoAndStop(1, 'exitLevel');
btnExitLevel.addEventListener(MouseEvent.CLICK, levelSelect1);
private function clearLevel():void
stage.removeEventListener(Event.ENTER_FRAME, update);
stage.removeChild(buttonCreep1); stage.removeChild(buttonCreep2);
for (var i = creep1Array.length - 1; i >= 0; i--)
removeChild(creep1Array[i]);
creep1Array.splice(i, 1);
//trace ("Creep1 Removed");
for (var j = creep2Array.length - 1; j >= 0; j--)
removeChild(creep2Array[j]);
creep2Array.splice(j, 1);
//trace ("Creep2 Removed");
for (var k = tower1Array.length - 1; k >= 0; k--)
removeChild(tower1Array[k]); tower1Array.splice(k, 1);
for (var l = tower1BulletArray.length - 1; l >= 0; l--)
stage.removeChild(tower1BulletArray[l]);
tower1BulletArray.splice(0, 1);
After debugging, it says the error is at the end, where i try to remove the child from the stage. What is wrong? Sorry, I'm a beginner at as3 so any answers might have to be spoonfeeding... I'll try to learn and understand, though. Thanks!
I did take some of the code off of a guide on the web, and I don't understand it totally, so can someone explain to me what this code does as well? What is e.currentTarget? Thanks!
var newLaser1:MovieClip = e.currentTarget as MovieClip;
Here's the full .as file if anybody wants to take a look. http://pastebin.com/5ff4BQa5

Hi, I managed to solve the errors (kind of) by using this code.
for (var i:int = tower1BulletArray.length - 1; i >= 0; i--)
if (tower1BulletArray.parent)
tower1BulletArray[l].parent.removeChild(tower1BulletArray[l]);
tower1BulletArray.splice(i, 1);
However, the problem still persists that the bullets stay in the screen after I change the scene. Any solution? Thanks!

Change/ removal of Unit of Issue in Material master Work scheduling view

Hi,
Is there a way to remove Unit of Issue from Work scheduling view? it is giving error message as "this is being used in BOM". Even if we put deletion indicator also it is showing same error message.
Regards,

Do a CS15 for the material in question and make sure you go in the BOM and select the material and click on delete/remove you can then do this.
I have tested it and it works.

Removing movie clips in arrays

Hi there
I have this code in my Flash file:
for(bubble in bubbleArray){
     bubbleArray[bubble]._y -= 3;
     if(bubbleArray[bubble]._y < 370){
          bubbleArray[bubble].removeMovieClip();
I'm wondering, when I remove the movie clips should I also be popping them from the array?
I have an onEnterFrame function that attaches the movie clips and pushes them into the array, so I'm worried that if I don't pop them the array will continue to increase in size and slow down the movie. Is this the case, or will they be automatically removed from the array by the removeMovieClip() method above?

Looks like I spoke too soon. I imagined that removing them from the array would be easy, but I'm struggling.
The movie clip that is removed from its parent clip and should be removed from the array will not always be the first element in the array, and I'll need to remove multiple clips at a time. I've put in a trace action to trace the length of my array, and after about ten seconds it contains about 2500 elements, most of which have already been removed using the removeMovieClip() method. I'm worried this will slow down the movie.
So to clarify: How can I remove these elements from my array when I remove them from the stage?
I tried to include something like:
while(bubbleArray[0] == undefined){
     bubbleArray.shift();
but it caused Flash Player to freeze up. Also, if I trace bubbleArray[0] it is only "undefined" before something is pushed into the array. Once the clip has been removed from the stage, the trace just returns a blank line, not "undefined".
I'd appreciate any help.
Here is all my code:
stop();
splash.stop();
var i:Number;
var j:Number = 0;
var minBubbles:Number = 10;
var maxBubbles:Number = 20;
var bottomBubbleLimit:Number = 0;
var topBubbleLimit:Number = 1;
var bubbleNumber:Number;
var bubbleX:Number;
var bubbleY:Number;
var bubbleScale:Number;
var bubbleMinScale:Number = 30;
var bubbleMaxScale:Number = 100;
var fewerBubbles:Number;
var ring:String;
var ringArray:Array = [ringAnimation.ring1, ringAnimation.ring2];
var bubbleArray:Array = [];
ringAnimation.onEnterFrame = function(){
    for(ring in ringArray){
        if(ringArray[ring]._y > 370){
            bubbleNumber = (minBubbles + (Math.random() * (maxBubbles - minBubbles)));
            for(i = 0; i < bubbleNumber; i++){
                bubbleX = ((ringArray[ring]._x - (ringArray[ring]._width / 2)) + (Math.random() * ringArray[ring]._width));
                bubbleY = ((ringArray[ring]._y - (ringArray[ring]._height / 2)) + (Math.random() * ringArray[ring]._height));
                bubbleScale = bubbleMinScale + (Math.random() * (bubbleMaxScale - bubbleMinScale));
                ringAnimation.attachMovie("bubble", "bubble" + String(j), this.getNextHighestDepth(), {_x:bubbleX, _y:bubbleY, _xscale:bubbleScale, _yscale:bubbleScale});
                bubbleArray.push(ringAnimation["bubble" + String(j)]);
                j++;
    for(bubble in bubbleArray){
        bubbleArray[bubble]._y -= 3;
        if(bubbleArray[bubble]._y < 370){
            bubbleArray[bubble].removeMovieClip();
    trace(bubbleArray.length);
    if(ringAnimation._currentFrame == 6){
        splash.gotoAndPlay(1);
    }else if(ringAnimation._currentFrame == 12){
        splash.gotoAndPlay(1);
fewerBubbles = setInterval(reduceBubbles, 600);
function reduceBubbles(){
    if(minBubbles > bottomBubbleLimit){
        minBubbles--;

Help: Random code selecting removed array item.

Hello struggling with this bit of code.
What im trying to do is whenever pickCircuit function is called, randomly color a button and remove it from the array so it cant be "selected" again.
The problem: my code is still selecting deleted items off the array.
//array
var brkArr:Array = ["1","2","3","4","5","6","7","8","9","10","11","12","13","14","15","16","17","18","19","2 0","21","22","23","24","25","26","27","28","29","30"];
trace(brkArr);
function pickCircuit (){
//randomizer
var brkRa:Number = Math.ceil(Math.random()*brkArr.length);
trace(brkArr.length);
//change color
var brkPik:ColorTransform = new ColorTransform();
brkPik.blueOffset = 150;
this[("brk" + brkRa)].transform.colorTransform = brkPik;
removeItemArray(brkArr,brkRa);
// Code removes items from array
function removeItemArray(thearray , theItem):void{
          trace("Remove "+theItem+" from "+thearray );
          for(var i:int=0; i<thearray .length;i++){
                    if(thearray [i]==theItem){
                              thearray .splice(i,1);
                              break;
          trace(" array is now - "+thearray );
any help would be appericated

use:
//array
var brkArr:Array = ["1","2","3","4","5","6","7","8","9","10","11","12","13","14","15","1 6","17","18","19","20","21","22","23","24","25","26","27","28","29","3 0"];
trace(brkArr);
function pickCircuit (){
//randomizer
var brkRa:Number = Math.floor(Math.random()*brkArr.length);
trace(brkArr.length);
//change color
var brkPik:ColorTransform = new ColorTransform();
