• for loop in formula node does not

  Hello

  I; m trying to use for loop in the node of the formula, but it is does not work. I want the output (y1) product value in certain range (a and d, and of course one is smaller than d). I ' do not use primitive labview since a and d are keep changing (both are variable). I tried to put "return 0;" after the y1 equation but the error popup.

  The issue of the loop works not because it gives the last value (I average would be ""). It does not begin with an (initial) value.

  Please help me how to solve this problem...

  Pls ignore other variables not used in the equation. Thank you!! A lot

  Your code works.

  

  But why you use loop?
  You get the last value, so you can get it in a single step with x correct;

  Also why you say that can not use primitives?
  If you use wire instead of terminals or local variable States values constant.

  Y1, y1_2, y1 3 is the same values calculated differently.

  

• parallel for loops does not

  Hello.

  I'm learning the multi - thread programming. To start, I use "parallel for loops" and I was surprised that it does not work. One - thread loop work a few times faster (depending on settings) that multi - thread. I don't know why, and it is my request to correct my Vi to work properly.

  A parallel FOR loop has an overhead for parallelization (split the problem, then go back the results, etc.). If the code is very fast, the overhead is proportionally larger. If the Subvi takes a long time to complete, the overhead of parallelization is insignificant. It is often not worthwhile to parallelize the loops with a very simple and fast code.

• Is it possible to put the property inside the loop node?

  I created three nodes of separation of property (color graphics) for my 3 XY graphs.

  Is it possible to have a property node, put this tag inside the loop where I ranges from 1 to N, and say plot_color_i

  where plot_color_1 would update 1 XY graph, plot_color_2 update XY Graph 2, etc. ?

  See the attached VI.

  Yes.  Create an array of references to the XY graphs and have this auto-index in the property node in the loop For

• Have different conditions for loop start and stop

  I do a VI when a circle is moving on an image control and its movement is decided by programming, but also by the user. I have programmed the speed of the circle as a vector which turns (using a rotation matrix) when a certain condition is met. This condition is dependent on the position of the circle and direction as well as other entries. The tricky thing is I want to that when the rotation condition is met (true), the rotation continues until the angle of the vector is equal to the original angle (when the condition became real) + / variable x.

  So my question is how do I program a piece of code that once activated, will run until a stop (depending on the State of vector early in the race) condition is reached. As it should be when the VI is on, I can not put a while loop inside an another while loop. Online help mentions also conditional for loops, but it isn't available in my version of LV (8.2)

  The correct solution is a state machine with a case inside a single while loop structure. Based on the need to use one of the several cases and move on to another matter as necessary using a state variable (for example, an enum) in a registry change. One of the cases should be slowed down and not do much except maybe controls survey.

  There are a lot of models.

• Check if for loop finished

  My question is how to check if the for loop complete? I'm controlling a supply of Genesys Lambda and taking a linearity data. I need to check if the loop is completed, ask the user to reverse polarity and resume data. Got only the first part of work. Looks like I can't just check the loop for the last iteration.

  I have attached my code for anyone to check if possible.

  Thanks for your help.

• How to create parallel tasks using parallel for loops

  Hello

  I'm going to put in place a program that communicates with the six logical controllers and must read the status of the system every 100 Ms. we use OPC datasockets for this, and they appear a bit slow.

  I created a uniform method of comm. for all controllers, and now I find myself this method of programming six times to communicate with each system. I was wondering if it could be done more elegant using the parallel for loop, in which case I program an Exchange once and then six workers running simultaneously. Since a picture is clearer than a thousand words, what I'm asking is:

  Is it possible to replace something like

  

  by

  

  and that for performing these tasks in parallel loop (on different cores / in different threads)?

  I have configured the loop to create instances of the 8 to the compilation, so I would 2 surplus available when running instances if I find that I need an additional system.

  The benefits of the Show method in the second photo for me are:

  * takes less space

  * changes need be made only once

  * less blocks, son and other things makes it clearer what is happening.

  * flexibility of the actual number of tasks running (8 available runtime instances)

  * If multiple tasks are necessary, I need only update the maximum number of instances and recompile, i.e. no cutting and pasting necessary.

  Unfortunately, I don't have these available system yet, so there is no way to test this. Yet, I would like to know if the above works as I hope - unfortunately the help of labview is not quite clear to me on that.

  Best regards

  Frans

  Frans, the parallel for loop will work as expected in this situation. The six tasks will run simultaneously in different threads. What part of the aid could be made clearer?

• JavaScript for loop to execute Advanced Actions - execute Javascript does not?

  I use a loop to check the value of a Cookie.  When I add this using Execute Javascript it works fine but I want to run with certain other actions, if I want to use Of execute advanced Actions. When I add this coded to an action to run Javascript in the breast to perform advanced Actions code disappeared if I open the Script window again once.  I try to remove the code for loop in bold below and then the remaining code remains.  So I think that the problem must be with the loop for, but I don't see anything wrong with this code and I have, as I said that this code works fine if I use Javascript to run on its own. I've attached a video clip below to show what I mean.

  var task1_value = readCookie ("task1");

  function readCookie (name) {}

  var nameEQ = name + '=';

  var CA = document.cookie.split(';');

  for (var i = 0; i < ca.length; i ++) {}

  var c = ca [i];

  even if (c.charAt (0) ==' ') c = c.substring(1,c.length);

  If (c.indexOf (nameEQ) == 0) return c.substring (nameEQ.length, c.length);

  }

  Returns a null value.

  }

  I found that window JavaScript of CP does not like loops.

  Your best bet is to put the function in an external JS file from the top of the page. I always run scripts in an external file. Really helps debug that you do not have to republish Captivate. Just change your code and refresh the browser. If you use external file you can store all your functions there.

  I would also look into using the local storage instead of cookies. Very easy to implement and you can store a ton of information.

• Passing an associated variable number between 'for' loops and functions?

  Hello

  I seem to have a problem with the information how variables can be passed between functions and tables.

  I have variable 'capture' put in place as a number.

  grab var: number;

  My intention (I'll do my best to explain) must have a number 'attached' to catch when it is mentioned for the first time in this function, itemClick.

  These must be all relevant tables:

  clickItemArray = [scene_Camp.wood, scene_Ax.ax]

  itemUsableArray = [wood2, ax2]

  ...

  sceneGuyArray = [scene_Camp.guy_Camp, scene_Ax.guy_Ax]

  function itemClick(event:MouseEvent) {}

  for (grab = 0; enter < clickItemArray.length; grab ++) {}

  If (clickItemArray [type] .hitTestPoint (mouseX, mouseY, true)) {}

  addEventListener (Event.ENTER_FRAME, itemRemoval);

  sceneGuyArray [grab] .gotoAndPlay ("guy_Notice");

  trace ("guy_Notice");

  }

  }

  }

  I would like to have the number in place with grab (it would be a 0 or 1, clickItemArray, sceneGuyArray and itemUsableArray) can be passed on to the next function, itemRemoval. I was hoping to use variables I can use the same function for some point clicked on. For example, if the clickItemArray was point 1 (the axe), then sceneGuyArray [Enter] would be = 1, and would play the right frame. Number 1 would be transferred to the itemRemoval function, where he would constantly be listening to sceneGuyArray [1] also (where '1' would have been obtained through the initial 'grab' in the first function) and react accordingly.

  function itemRemoval(event:Event) {}

  for (var grab2:uint = grab; grab2 < sceneGuyArray.length; grab2 ++) {}

  If (sceneGuyArray [grab2] .currentLabel == 'guy_NoticeDone') {}

  removeEventListener (Event.ENTER_FRAME, itemRemoval);

  trace ("cheese");

  }

  }

  }

  I can't get the track works well. I don't know I'm doing something wrong with 'for' loops or the stated case.

  Naturally, help would be appreciated.

  then, in itemClick(), use:

  Grab = itemClickArray.IndexOf (Event.currentTarget)

• Global variables and for loops

  Hello
  
  I am working on my project for my programming course (a game of Connect 4) and am now in gritty step to rewrite all the code to make look it somewhat professional. Was it the original... disaster: http://zephyr.pastebin.com/7kfyaMRY--Oui, I know who will probably do someone of you cringe. I try to avoid the massive chain of JPanel panelXxY = new JButton(""); using loops for. I need to keep global variables so that I can call in my actionPerformed method, but apparently you can not put a loop outside of a method or main and even if you could, apparently all variables declared in a for loop said would not exist outside this loop. So, any suggestions? Keep in mind that I only knew even what a string for all... 10 weeks, so please nothing too complicated.
  
  Thank you ~.

• For loop in place, images to scale and move

  I have an image which I enclose, is the white part of the image (I recorded it on a black background so it is easy to see, but it's on a transparent background, saved as a gif file and imported to flash). When my for loop runs, I'm trying to put this image on stage by programming, but it seems that it is not doing things. It will scale the image and positioned some in all directions

  I wanted the images (8) appears in 2 columns each staggered regularly, but he fails to do so. The clip holds the image below. Since it is an irregular shape, it also seems to make the edges really rough.

  (1) why is the loop generating these images in all directions like this?

  (2) it would be more ideal to draw this shape with flash, rather than by using a gif image? Such a form is even possible to draw?

  This is the code:

  Fl.transitions import. *;
  Fl.transitions.easing import. *;
  import flash.events.TimerEvent;

  var imageLoader:Loader;

  var xmlData:XML;

  var bucketItem:MovieClip; They hold the attached picture
  var bucketHor:MovieClip;

  placeBuckets();

  public function set {loadedXML(xml:XML):void}
  xmlData = xml;
  }

  function placeBuckets (): void {}
  var all: Number = 50;
  After var: number = 115;
  
  var bucketCount:XMLList = xmlData.product;
  for (var u: uint = 0; u < bucketCount.length (); u ++) {}
  bucketItem = new bucket();
  bucketHor = new bucketr();
  
  If (bucketCount.country.text ([u]) == 'USA') {}
  1st = bucketItem.y;
  bucketItem.x = 100;
  var bucketTween:Tween = new Tween (bucketItem, "x", Regular.easeOut, bucketItem.x, 0, 0.5, true);
  } else {}
  bucketHor.y = after;
  bucketHor.x = 300;
  bucketItem.scaleX = - 1;
  var buckettwoTween:Tween = new Tween (bucketItem, "x", Regular.easeOut, bucketItem.x, 0, 0.5, true);
  }
  var bucketImgTrans = new TransitionManager (bucketItem);
  bucketImgTrans.startTransition ({type: Zoom, direction: Transition.IN, duration: 3, easing:Strong.easeOut});})
  var bucketImgTransH = new TransitionManager (bucketHor);
  bucketImgTransH.startTransition ({type: Zoom, direction: Transition.IN, duration: 3, easing:Strong.easeOut});})
  trace (bucketItem.y);

  trace (bucketHor.y);
  addChildAt (bucketItem, 0);
  addChildAt (bucketHor, 0);
  After = (after + 200) - 115;
  1st (1st + 130) = - 50;
  }
  }

• parallel processing: for loop taking place

  Hallo,

  I have a loop 'for' runnin on this system: LabVIEW2009, windows7, intel i7.

  I wonder if and how I can tell to LabVIEW that he would be allowed to run different iterations of the loop at the same time (concurrently) on my processor with 8 cores.

  Now, it will execute the next iteration when it ended the previous, even one so is there no dependencies in iterations.

  I want to give a 'ownership' of the loop, which means that it can be "unfolded" for parallel execution.

  Thank you

  pop up on for loop and select "configure interation Prallelism."

  Activate it.

  Wire a certain number to the new 'P' of entry to specify how many processors to spread it everywhere.

• For loop runs with the value of N unwired

  In this case will be a loop run connected to the loop N worthless? I have seen a few examples of the loop for run without a certain number of times set to be ran wired or for example a size of table or something like that.

  PauldePaor wrote:

  Here's a program I am and as you can see the image that the program runs without the loop N being wired. The program will run without problem

  As everyone else has said, you don't have to plug something on N.  If you wire up a table for loop for input "auto-index", the loop for will run automatically the smaller table size.

  Perhaps an example will help:

  

  This makes a loop on my table size (in this case, long of 5 elements).  On the edge of the loop for which resembles [] brackets, indicates that it is auto-indexé.  The loop should go through each item one at a time (1, then 2, then 3, then 4, then 5).

• For loop creates 1 d data table

  Hello, I am building the circuit below, and I'm running into a lot of problems with the loop, creating a table 1 d of data from certain types of data such as the ERROR OUT and the VISA NAME of RESOURCE. I understand why it does this, but I only need the last value in the table (the value of the last iteration of the loop for). This is true for me for the error, resource name of visa, and I was thinking of using the Boolean value that indicates when the for loop.

  Is there a simple way to extract the last value in the table 1-D so that it is correct to pass along trails, VISA and ERROR type?

  You actually create a block diagram, not a circuit.  A circuit is an electrical system including devices and wires.

  If you right-click on the tunnel and choose disable indexing, then you get the value of the last iteration rather than a 1 d table.
