• Restarting a task for the acquisition of data inside a For loop

  Hello

  I need iterate through my acquisition of data. Currently, I'm doing this through the creation, implementation and tasks for the acquisition of data inside a loop For which is iterated according to the needs of compensation. Unfortunately, the creation of these DAQ tasks slow down my code.

  I would like to be able to create the tasks outside the loop, pass them in and revive the tasks at the beginning of each iteration. Is there an easy way to do this?

  Otherwise, is there a way to make the standard DAQmx digital startup trigger trigger several times (so that it starts each pulse data acquisition in a long pulse rather than just the first pulse train)?

  Thank you!

• How to stop a flat sequence (or timed sequence) which is inside a loop for

  The problem is this, I have a loop that repeats 10 times and inside this loop, I have a flat sequence (or timed sequence) with four images, each of this chassis to evaluate a different condition of a vector that I introduce.

  What I woud like for example is:

  I'm a fifth County of the loop for and in the case that part 2 does not meet the condition, the sequence of dish (or timed sequence) stops and starts the loop again but this time for the number of number 6.

  I would appreciate your response.

  You can't stop a sequence structure.  This is how they are made.

  What you should consider to get rid fo structures sequence and to change a state machine architecture.  There are many examples in LabVIEW, as well as on the Forums.  The big advantage of the state machine is that at the end of each State, it examines the conditions and determines which State then run. And that is exactly the description of the problem you are experiencing.

• Cannot use Select inside the loop For inside the SCTL (FPGA) - Bug? An alternative?

  When I put a Select statement inside a loop in a loop of Timed Cycle in LabVIEW FPGA, I get the following error when I try to compile:

  "An internal software error occurred. Please contact National Instruments technical support on ni.com/support with the following information:

  Error-61003 occurred at

  Possible reasons:

  LabVIEW FPGA: you cannot include this function in a loop For when the loop is within a single cycle timed loop. »

  I didn't know that whatever it is documented that says that this is not allowed; is this a bug or am I missing some documents?

  The code that causes this error looks like this, inside a SCTL (ignore Boolean wire wandering behind the loop for)

  

  I came up with the code below instead, which compiles into one Cycle timed loop, but it is a bit ugly. Does anyone have a better suggestion?

  

  This issue is currently followed under the CAR # 592391. Please keep an eye on our patches and new versions as usual!

• Schedule iteration five FOR lines inside a timed loop...

  Take a look at the attached code simply run five different but identical TO the lines inside a single loop timed.

  It is interesting to note the timings of each loop iteration FOR: 1,1,2,3,0 milliseconds. The most curious is the moment of the last loop, which for the most part indicates 0! Not only this, if you remove the fifth loop, the fourth a bed 0.

  I can't understand this behavior? Also if LV deals in parallel different loops why should there be a gradual increase in the synchronisation of successive loops?

  Thanks for any help.

  First, 0.2 ms is not statistically significant, you must increase the number of iterations by another factor of 10, at least.

  A quick loop uneducated wait FOR will grab the CPU for much more than one iteration, so regardless of the loop is first online will repel the other loops and run until LabVIEW decides to switch to another loop. The number of cores CPU do you have?

  You can force a release after each iteration by placing a 0ms wait inside each loop FOR. While all time will be significantly longer because of the overhead of increased switching, all loops will be now around the same time.

  You can also read this for more information.

  I don't know that anyone else can provide more details in the jargon of right. I don't know the correct terms for all this.

• Event inside the loop 'for' confusion

  Hi all

  I have an event inside a N = 2 for the loop, which generates an array of 2 elements (auto-index mode). The first value is a first event, the second of the second round. The events are the mouse clicks on a front panel with many buttons control.

  Am I able to access the i counter inside the front loop of 2 elements output table? He does not appear.

  Maybe I want just 2 events in the order I should put two copies of this event in a sequence of 2 image... but it creates the need to set up the event twice... a concern, because it contains many possible sources.

  Ive tried everything in loops, by the way I like a local variable, tunnels, shift... registers but I don't seem to be able to access I have during the loop.

  Can anyone suggest a method or a better structure/approach for this issue.

  In any case, it seems that the program is blocked waiting for the second round, so I can't do anything with the value anyway?

  I want to take action after the first test and before that I'm waiting for the second event.

  Thank you

  Carloman

  OK, you're much too complicated things dong.

  • Use a unique event for all low Boolean mice, then use the ctrlref of output event to detect only one. For Boolean values, you can use an array of Boolean instead of all these individual buttons.
  • Don't do the "table of cluster... unbundle" songs and dances. It's just ridiculous! 'array Index' is sufficient.
  • You need an event for the stop button.
  • The structure of your outdoor sequence has no purpose.
  • The coloring is registered with VI, no need to recolor with each race.
  • Do not reproduce any of this code. Your internal matter differs only in a constant of the diagram, it's everything that belongs inside the case. The "subset of table to replace" belongs to the outside.
  • Now, simply do the processing in a new event and ignore if the State isn't fair. Modify if needed.

• creation of an area of dynamic text inside a movieclip using a loop for

  I'm having issues creating several areas of dynamic text inside a movieclip using a loop for.  I use 2 ACEs.  Here is the code I've created so far

  var leading: Number = 0;

  function drawClip (): Void

  {

  this.createEmptyMovieClip ("mc", 10);

  for (i = 0; i < 5; i ++)

  {

  mc.createTextField ('text areas' + i, this.getNextHighestDepth (), 0, leading, 200, 200)

  MC ["text boxes" + i] .text = i;

  leader + a = 20;

  }

  }

  drawClip();

  Create a mc but she only display the number 5

  Any thoughts?

  You are cionstantly, crushing the textfield created previously due to the use of the wrong depth define.  You point to 'this' to get a depth value, but he planted inside 'mc', so it's always at the same depth since "this" index of depth does not change.  Use...

  mc.createTextField ('text areas' + i, mc.getNextHighestDepth (), 0, leading, 200, 200)

• Define the actions of the buttons inside a loop for

  Hi, me again ^^
  This round is:

  I got a set of buttons and a text field where they load the content.

  I try to take a zillion functions and keep the neat code so I guessed I'd try set the actions to the buttons in the loop too. First of all, I had a few problems to the I counter inside the function onRelease (in fact I don't think I've ever had how do). But I tried this and it worked:
  Stop();
  var comprarXML = new XML();
  comprarXML.ignoreWhite = true;
  comprarXML.load('flash/comprar.xml');
  comprarXML.onLoad = checkLoading;
  function checkLoading (success) {}
  rootNode = comprarXML.firstChild;
  ButtonReleaseAndContent ();
  }
  function ButtonReleaseAndContent () {}
  for (i = 0; I < 12; i ++) {/ / my buttons are not dynamically generated, which is why the County.}
  btTemp = eval ('content.test.bt' + i);
  btTemp.txt.htmlText = rootNode.childNodes [i + 1].firstChild.firstChild.nodeValue;
  btTemp.temp = rootNode.childNodes [i + 1] Sublst.ChildNodes(1).ChildNodes(0) [1].firstChild.nodeValue;
  btTemp.onRelease = function () {}
  this.temp = content.test.test.htmlText;  the problematic line
  }
  }
  }
  On line where I put the text, I had one if "uh Yes, I may be refer to in the mc button, because the generated code goes in! So, I tried the this.temp, guessing it would be equal to the level of the key. A few seconds later I noticed that my SEO for the text field was not coming in the button, but the root. So I have no idea why this works. Anyone know what I did?

  If btTemp is a movieclip to assign dynamic properties (such as temp).  You can then retrieve this property when the button is released.

• Cursor inside a loop FOR?

  Hello
  
  We will declare or define a cursor inside a loop FOR?
  
  -Vijay

  Yes, it is possible that the definition take place inside the part of the plsql block code, the syntax looks like:

  for rec in (/*here you define cursor with select query*/) loop
    ...
  end loop;
  

  I think that if you do not use a variable/slider several times, it is advisable to set the cursor with the loop for. If you want to use the cursor over a school then it should be defined in more global place.

• The sum of several waveforms, created inside the loop for

  Hello

  I am currently viewing the Gibbs phenomenon by adding several sine waves. The issue I'm having is that I can't understand how to add sine waves created in the loop. I have attached a picture of the basic structure for my project below. I tried to use simply "add" with a feedback loop, but it seems that my programming skills apply here. Any suggestion is appreciated. Thank you!

  0

  Something like that?

  1. make sure that you "reset" the generation of signals with each iteration

  2. with the waveforms, please make sure that the sample rate is the same.  This may be a problem with the first iteration.  Then add in a check to use only the first waveform on the first iteration.

  

• If doesn't work is not inside the loop for the registration of the declaration file?

  Hello!

  I have the following documents open in Photoshop:

  123456_mrp_ou. TIF

  869548_mrp_ou. TIF

  896589_mrp_in. TIF

  896589_mrp_ou. TIF

  .. and I have this if statement in a loop for to search for files with a specific 'pid' number and save them in the folder My Documents:

  var originalPid = 896589
  for(i = 0; i < app.documents.length ; i ++) {
        activeDocument = app.documents[i]
          if(activeDocument.name.substring(0,6) === originalPid) {
                  var standardSave = new File('/Users/constantincerdan/Documents/' + activeDocument.name)
                  activeDocument.saveAs(standardSave, TiffSaveOptions, false, Extension.LOWERCASE)
  }
  }
  
  
  

  It did not find the two files and save them when I run. However, the loop without if statement runs very well and saves all the documents in the Documents folder:

  var originalPid = 896589
  for(i = 0; i < app.documents.length ; i ++) {
        activeDocument = app.documents[i]
                  var standardSave = new File('/Users/constantincerdan/Documents/' + activeDocument.name)
                  activeDocument.saveAs(standardSave, TiffSaveOptions, false, Extension.LOWERCASE)
  }
  
  
  

  How it works with an if statement so that it saves only the two?

  Any help is very appreciated!

  You are comparing apples to oranges, you need to compare strings.

  originalPid = 896589;

  alert (typeof originalPid);

• Create a directory tree: how to call a global function from inside a for loop

  Hello

  I am trying to create a workflow that will create a directory tree in vCenter.

  Concept:

  Basically, I am trying to execute nested for loops for each level of the tree to the caller a global tree.

  Problem:

  The 1st loop for works and creates the file 'Dev '.  The second loop for does not work with error message:

  [19:16:16.219 2013-06-27] [I] building Dev folder
  [19:16:16.474 2013-06-27] [I] directory Built: Dev

  I think it has to do with JavaScript not being not able to call a global function in a nested object (I'm not a programmer and don't know JavaScript, so don't shoot me on that :)

  Code: (will clean this up once I do work)

  var folderBase is ['Dev', 'DMZ', 'Prod', 'UAT'];.

  var folderT1 = ["servers", "Jobs"];

  var folderT2 = ['Window', 'Linux'];

  var folderT3 is ["Repo2', 'Repo3', 'Repo1', 'Repo4'];.

  var folderT4 is ["T1", "T2", "T3"];.

  Create the files folderBase level

  for (var i = 0, l = folderBase.length; i < l; i ++) {}

  var rootFolder = parentFolder;

  buildFolderTree (folderBase [i]);

  Create the files folderT1 level

  for (var j = 0, l = folderT1.length; j < l; j ++) {}

  var rootFolder = folderBase [i];

  buildFolderTree (folderT1 [j]);

  Create the files folderT2 level

  for (var k = 0, l = folderT2.length; k < l; k ++) {}

  }

  Hello

  The createFolder() method returns the object VcFolder to the folder just created, for the new file to be used immediately.  Here is how I modified the code:

  Create the files folderBase level
  for (var i = 0; i)
  var newBaseFolder = buildFolderTree (parentFolder, folderBase [i]);
  Create the files folderT1 level
  for (var j = 0; j)
  var newT1Folder = buildFolderTree (newBaseFolder, folderT1 [j]);
  Create the files folderT2 level
  for (var k = 0; k)
  var newT2Folder = buildFolderTree (newT1Folder, folderT2 [k]);
  Create the files folderT3 level
  for (var x = 0; x)
  var newT3Folder = buildFolderTree (newT2Folder, folderT3 [x]);
  Create the files folderT4 level
  for (var y = 0; y)
  var newT4Folder = buildFolderTree (newT3Folder, folderT4 [y]);
  }
  }
  }
  }
  }

  function buildFolderTree (parentFolderObj, folder_name) {}
  System.log ("Building folder" + folderName);
  var newFolder = parentFolderObj.createFolder (folderName);
  System.log ("directory of frame:" + folderName);
  return NewFolder;

• OSB: Replace the action inside a loop for

  Hi all
  
  She seems like a simple question but I'm breaking my head for now quite sometimes.
  
  I have a recurring element in my diagram. I need to get the value of this repetitive element and convert it to uppercase.
  
  For example:

  My XML
  <Telephone>
  <Telephone Number>
  <phoneUsage>Contact</phoneUsage>
  <phoneNo>767676</phoneNo>
  </Telephone Number>
   
  <Telephone Number>
  <phoneUsage>Callback</phoneUsage>
  <phoneNo>767676</phoneNo>
  </Telephone Number>
  </Telephone>

  I need to change the value of using phone uppercase (reminder and Contact)
  
  For this I use a loop For:
  

  For variable TelephoneNumber in ./Telephone/TelephoneNumber of variable body
  Indexed by variable TelephoneNumberIndex with total count in variable TelephoneNumberCount
   
  Do
  (
  Replace $body/Telephone/TelephoneNumber/phoneUsage in variable body with 
  fn:upper-case($body/Telephone/TelephoneNumber[xs:int(i)]/tro:phoneUsage)
  )

  I do not know how to move the index value in the Xpath expression replace $body, phone, TelephoneNumber, phoneUsage.
  Can you help me please on this? I tried $ phone/body/TelephoneNumber [xs:int (i)] / / phoneUsage, but it generates an error.
  
  Thanks in advance for your time and support.

  For each [TelephoneNumber] in [. / phone/Tel...] ./Telephone/TelephoneNumber
  [body]
  Indexed by [undefined Variable] with countdown in [undefined Variable]
  Do)

  Replace [content of the node] [. / phoneUsage]. / phoneUsage
  in [TelephoneNumber] with [fn:upper - case ($...)] fn:upper-case($TelephoneNumber/phoneUsage/text())

  )

  Kind regards
