• Removing a specific element of a vector

  I wonder how to remove a specific element of a vector.

  For example, suppose you have the following method:

  private var element:String;
  private vare Element:Vector<String>;
  
  //This function assumes that Element has elements in it.
  public function removeelement(element):Boolean
  {
       for (var i:int =0; i<Element.length; i++)
       {
            if (element == String(i)
            {
                 //How do I remove the element assuming it matches?
                 return true;
            }
       }
  
       return false;
  }
  

  So from the above example code I was using Element.pop () but it's wrong - I think - as it removes the LAST element. I need to remove the item at the location of the match.

  Hello

  You can use splice to delete items, but you must execute the loop starting with the last element (and precalc length as it will change if items are removed) to avoid errors:

  var len:int = element.length;

  for (var i: int = len-1; i > = 0; i--)

  {

  If (item is String (i))

  Element.splice (i, 1);

  }

• Remove the array without the local Variable element

  I am wanting to know if you can remove an element of an array, the index of the removed part.

  and update the value in the array to not include the deleted part of a more direct way than the following:

  

  Or, in my program, the table is initialized with some clues that makes the task of removing an element of

  table, the part removed from indexing and updating the table includes only not the deleted part similar to the following:

  

  (a) is there a way to do this without having to use local Variables?

  (b) I would be so concerned to rid my program of all local Variables? (even those who don't create race conditions)

  Keep the table in a feedback node initialized in the world. Do not imply not objects of façade.

• mathematical calculation in script on each element of the array.

  Hi all

  I am trying to write the VB script in which I want to do different mathematical operation on each element of channel-specific data. For example, for each element I want to find the next two index given way and both before and after publication of the results on the basis, then it is more calculating.

  It will be very useful if someone can guide me in the execution of operation on the elements in the array inside the script of tiara, that we can do in labview using indexes in the table. There are built-in math and statistics in tiara tab analysis tool. But I want to design for my custom mathematical operation.

• Type a table defined clusters to hold configuration data - definition of default values for each element of the array

  Hello

  I was wondering if I could get some information and opinions on the use of an array of type defined clusters to store configuration data.  I am creating a program to test several EHR and wanted to have a control of type defined for each HAD with the information needed to create the DAQmx tasks for all signals for it must HAVE.  I am eager to do so that the data are encoded in hard and not in a file that the user might spoil.

  Controls of type def are then put into a Subvi who chooses as appropriate, one based on the enumeration of Type DUT connected to a case structure.

  I have problems with the control of the defined type.  I see issues when you try to save a configuration unique to each element of the array in the array of clusters.  Somehow, it worked at first, but now by clicking on "Operations on the data--> default font of the current value ' on individual elements of the cluster or the entire cluster (array element) does not save data when I re - open the command def.  What I am doing wrong?  I'm trying to do something with the berries of the clusters that I shouldn't do?

  I enclose one of the defined reference type controls.  I tried to change it bare to see if that helped, but no luck.

  To reproduce, change the resource string for the element 0 of the array and do the new value by default.  Then close the def of type, and then reopen it.  The old value is always present in this element.  The VI is saved in LabVIEW 2012.

  The values of a typedef are not proprigated to the instances of the control. They get if created WHEN data values have changed. They will be not updated with the changes to come. You must create a VI specifically to hardcode your values or to implement a file based initialization. The base file would be much better and more flexible. If you don't want users to change the data simply encryption. There is a wedding blowfish library that you can download.

• Drag and drop the element of the array of Clusters

  I have a project that includes an array of 'tests', each of which is a cluster that contains an array of 'numbers', a matching the regular expression string and an array of "tasks" (all of them, is in turn, a group of elements).

  It is:

  • Tests (table of):
  • • Cluster:
    • • Reference numbers (an array of strings)
      • Regex (string)
      • Tasks (table of):
      • • Cluster:
        • • Task type
          • Basic channel,
          • Measuring channel
          • Other channels

  I wish I could drag and drop to rearrange the task table in an individual event.  (It is a nice-to-have rather than a urgent request - more for my own learning that no matter what).  For now, I've implemented "Move up" and "Move down" buttons

  Examples are fine for a single cluster that includes a table or an array of objects.  As soon as we have an array of clusters, it is difficult to access individual items within a specific cluster.

  Who that it be completed can drag and drop into such a facility?

  Curiously,.

  Geoff

  Hello GeoffF,

  It's certainly doable and you can even use the standard start drag and drop methods/events, the trickiest part is to determine the table of the elements that are selected on the mouse towards the top/mouse downwards and the swap of manual handling.  Fortunately, there are a few decent examples of how do this out there already, I suggest you take a look at this one:

  Example of community: determine the Index of the clicked element Array in LabVIEW

  https://decibel.NI.com/content/docs/doc-22434

  That should give you the selected table indexes, and then all you have to do is to move the elements around around the drop event.  I have attached a very basic demonstrative example that uses this code I just linked (you need to download that as well) and the events referred to swap two elements of the array.   The attached code is just thrown together, you'll want to design something more robust and scalable to any sort of actual use.

  Kind regards

• Remove the equidistant indices into an array

  Hi all

  I have a performance problem. In my code, I use two nested for loops. Externally, runs 500 times each time. Rather, an internally executes once for every pixel that I find in an outline to a picture. Number can range from 10 to 1000. And 500 x 1000 is a large number of iterations. In addition, the difference between the e pixels is minimal, I needn't pixel to build an outline.

  So I thought to leave only 50 pixels to define a contour and whenever I get a certain number of pixels, the vi "remove table" allows to reduce the amount of pixels at 50. But I would avoid for loops, because computational cost would increase even if I need to go on the entire table. For example, if I have 20 pixels, and I want to reduce them to 10, I would choose index 1, 3, 5, 7, 9, 11, 13, 15, 17, 19.

  I don't know if this is possible. Can you help me please?

  I cheked this post:

  http://forums.NI.com/T5/LabVIEW/removing-a-list-of-indices-from-an-array/TD-p/572652

  but this isn't the same problem he uses for loops, in fact, I would say that mine is easier to solve and perhaps very banal, but I can't find a solution.

  Thanks in advance.

  Using Index table inside a loop will produce the results you want and can work quickly enough.  The attached VI selects an item in each element of the 'period '.  For testing purposes, I have two tables, one random DBL and another of sequential I32. The array of integers allows a quick check you get the tables you want.

  When it is used as a Subvi with closed Panel, this averaged 33 microseconds with 1000 pixels and periods of 50 or 100 tables.  The loop Tester ran ~ 200000 iterations before I stopped to check the timing.

  This corresponds to about 17 ms for your configuration of 500 x 1000.

• Remove Cluster border control in order to reduce the size of the array of cluster

  Dear community

  I have a long pending issue. We want to build such a chart legend by the use of an array of clusters. See photo.

  As we have these lists more often, we would like to get rid of unnecessary borders cluster using the cluster as an array element. (could also be called advanced multi-column listbox)

  I've seen a solution to a similar problem when you use the image control.

  http://forums.NI.com/T5/LabVIEW/remove-picture-control-frame-for-a-picture-array/m-p/3107081/HIGHLIG...

  I tried this for the cluster, but it is not 100% successful, as the cluster control does not have two separate objects.

  You know a way to remove the gap between the components of the cluster completely or bring to an absolute minimum.

  The photo shows a first step, but it is not possible for me to further reduce.

  

  I thank in advance for your suggestions.

• to access the array elements

  Hello, everyone

  I am new to labview, & I need your help please,

  I did sample of a sinusoid, and the value of each sample is stored in a table (point by point).

  now I need to access the array by one element, because I want to subtract first element by others, one by one, in descending order, for example, if the first element is x, and other elements are y, y1, y2, y3, y4,... I mean x - y, x - y1, y2 x, x - y3... I need to do to have an account for a given period calculate the frequency.

  Please,

  I need someone to tell me, how to subtract one by one of the elements of paintings that I showed in the attachments below:

  Hello tinamoli,

  I have saved the VI for LabVIEW 8.0, removed the labels confusing (sorry, altenbach) and I added a small example for autoindexing.

  If you wire up a table in a loop for autoindexing has to be enabled by default. If you click right a tunnel there is an option to turn on/off indexing.

  I hope this helps.

• Automatic indexing does not as soon as the first element of the array.

  Hello

  I have a state machine that uses automatic indexing in most of his State to write the registry to set the part for some test.  When the state machine reaches the section 'Now playing' (the fourth State, second battery sequence) I have a picture of two equal elements related to looping for to write the required registers for this specific test.  When I enter the current state read the the first address is the second element of the array which is '1' location and not the first address that must be '0 '.  I closed the program and restarted LabVIEW but I always get the second element in this loop that maintain the form part works correctly and I get an error because the first element turns on the chip.  Is there something I'm not see when it comes to self that he would keep from starting at the first element of indexing?  Please take a look and let me know what I can do wrong.  I have attached the main program and the print loop results screens and test probe.  Any help will be great.  It worked last week.

  I don't see no problem at all when I copy the loop in an another VI in order to run it. Your jpg shows nothing on the values of the probe.

• I just installed Photoshop and first element 14. Should I remove the previous version 11 from my computer?

  I bought 14 items, and I just want to know if I should remove the previous version. Thank you

  toegui

  As I already said in general...

  It is no doubt desirable to give Photoshop elements 14 and first Elements 14 each training before disabling and uninstalling the 11.

  Given the specificity of the 11 vs 14 that have been introduced, I would add the following...

  You depend on DV and HDV firewire data capture in the Capture window of first items as part of your workflow of video editing - before 11 or now with 14? As has been pointed out, 13/13.1 and 14 do not have this feature. The latest version which has this feature is 12/12.1.

  Purchased as downloads of Adobe programs? If Yes and deleted this is a deal breaker, you can go to Adobe to get return/refund within 30 days of purchase if you do not want work through workarounds for this situation Adobe or capture elsewhere and put the captures in Premiere Elements with add media files and folders of the program. Removal of features and unsupported file formats. Adobe Premiere Elements 13

  But, if you have purchased, you will be governed by the seller's return/refund policy. So if you have not already and the above is a problem, you don't want to break the seal on the packaging of the box if that's what you bought. Contact your dealer as soon as possible to request a return/refund if 14 does not include the necessary feature.

  I think that what follows is what has been referred to as for Photoshop Elements and color Variation

• remove the specific item in the arraylist

  Hey,.
  I just want to remove an element from a list of tables.

  private function addNewItem():void {
            object = new ObjectProxy();
            object.id = input.text;
            arrayList.addItem(object);
  }
  

  Now how can I remove the sound element identifying specific?

  something like this:

  arrayList.removeItem(object.id=="blabla");

  or

  for each (obj:Object in ArrayList){
            if(obj.id == "blabla"){
                 ArrayList.removeItem(obj.id);
            }
  }

  
  I hope you can help me.
  Greetings,
  Zombiecook

  Your second code example is close. Just remove the obj instead of the id when you find it like this:

  for each (obj:Object in list){          if(obj.id == "blabla"){               list.removeItem(obj);          }}
  

  Of course, it would be more efficient to simply do:

  for (var i:int = 0; i < list.length; i++){          if(obj.id == "blabla"){               list.removeItemAt(i);               break;          }}

• How to remove the point of my array

  Hi, I have a table with the elements. now, I want to remove all elements in the array. How can it be possible?

  It depends on what you mean by compensation. The delete operator sets an array to undefined element, the length of the array remains unchanged.

  for (var i: int = 0; i<=  yourarray.length();="">

  {

  delete [i] yourArray;

  }
