• Do nothing in the case structure with loop For

  Hello

  I am trying to extract data from my signal (0.3 0.4 0.6...). I want to extract values greater than 0.5 and put it in a table. If I use a loop For which I can determine each index of my data to be compared and it happened in the structure of the case. In the 'Real' box, I wanted the value to extract outside the loop For. And I want to "do nothing" if my value falls within the box 'False. ' However, it displays error, saying "' Tunnel: lack of assignment to the tunnel '."

  I tried to select 'Default', but it does not work since I use a Boolean comparison. I tried to use the registry to shift, but in vain too.

  Someone could guide me on this to extract only a value greater than 0.5 and index them?

  For example "0.6 0.7 0.8; 3 4 7 index.

• 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())

  )

• Control values defined by the Index function only works for a running VI?

  I've never used set of control values based on the Index before so I decided to compare it against two other ways to set the controls on the front panel, by using the invoke Ctrl.Val.Set node and nodes for the value property. But if the VI which I am trying to set the controls does not work I get error 1000 say "The VI isn't in a State compatible with this operation." When I run the VI which I am trying to set the controls, I get an error. This is VI really only work if the VI is running? I can't set the values before calling the VI to run dynamically?

  I wonder why you do so in the first place.

  a bit of history. This feature was added to the problem write to items in front by reference is about 1000 times slower than writing to the Terminal. I think that this feature works by writing directly to the transfer buffer. It always ends up by being slower than writing to the Terminal, but only about 10 times slower.

  My company made use of this new feature. We needed it because we have updated thousands of values of frontage on the same VI by reference and labview couldn't keep it up (Yes, probably could have worked around him in a different way, but there is more detail than this...). If your ' e does not update thousands of articles, probably you should not use this feature. Performance savings is not worth the additional development effort it takes.

  It does not work probably because the transfer buffer does not exist when the vi is not running

• Help with the efficiency of the program, stop a loop for?

  Hi all

  I need some advice programming General to help my VI to operate more effectively.  I have a table in which the program runs each point and 2d compares the value for the surrounding points.  The user can select the range of cells to inspect range, so if the user selects 1, then, it will compare the point (0,0) to all cells in a single cell.  If the user selects 2, then all the cells in a range of cells 2 and so on.  If the point (0,0) is superior to everything around him, then he writes this point in a table.

  I made more notes in the VI to explain what is happening, but I think that the program would be more effective if I could stop a for loop to run as soon as it detects a false condition, i.e. the point (0,0) is not more than one of the surrounding points.  As it is right now, it compares at all points around him, writing TRUE/FALSE for a table, then checks if all conditions are TRUE.  That takes a lot of time if the user selects a value of 8, for example.  It would reduce a lot of processing time if he just threw to the next point as soon as it finds a FALSE condition.

  Any other advice would be appreciated as well.  Try to be a more effective programmer!

  Thank you!

  I do not attach the data file, because it is too big.

  In versions before the invention of the loop For with conditional stay terminal, you can do it, but you have over what a while loop to stop when your condition is True, OR when the terminal i is equal to the size of the incoming array - 1.

• Timeline question on how I can change the time in a loop for

  In the following code segment:

  for(index in [0..3]) Timeline
  {
      keyFrames:
      [
          KeyFrame
          {
              time: 0s
              values: cars[index].translateX => 0

              time: 15s
              values: cars[index].translateX => 800 tween Interpolator.LINEAR
          }
      ]
  }.play();

  How can I make the time to be 15 + 2 * index seconds, for example, instead of 15 s always?
  
  Any input would be greatly appreciated!
  Thanks in advance!

  I imagine something like (not tested)

  var duration: Duration;
  var tmp = bind index on replace {
     duration = Duration.valueOf((15 + 2 * index)* 1000);
  }
  :
  :
  KeyFrame
  {
     time: bind duration
     values: cars[index].translateX => 800 tween Interpolator.LINEAR
  }

• Manipulate the subdashboards with a loop for?

  Hi all

  Here is a picture of what I'm trying to do: basically, I want to choose the (3 x 3) A subarray, manipulate data, then

  Select the subarray B (2 x 2), manipulate data, and finally select the (4 x 4) C subarray and manipulate its correspondent

  data. In my real problem, I have more than A, B, C. I have a number any variables.

  I have a 1 d table, below, that I use to make a kind of mapping to my 2D table so I can choose the appropriate sub-table.

  Please see the VI attached and see if my approach is logical. To be concrete, the end result of my VI must be a 2D array containing

  A, B, C and for each variable, I want the sum total of all the numbers corresponding to this sub-table.

  For example, for A, I want 1 + 2 + 2 + 2 + 1 + 5. My real data manipulation would be more complicated, but if I can understand this simple case,.

  the real case will follow.

  I do not know where to store each subbarray in my loop and WHEN to do my manipulation of data, it must be inside of the inside of the loop, outdoors, where? See the attached VI.

  Thanks in advance.

  

  I think you need a boot and wiring through the case of fake.

  Note that the output is a table to a dimension.  Because pages can be of different sizes, the pages 'A' and 'B' contain empty elements. If no match is found fo a 1 d, a full page table element will be empty. To see this 'B' to replace in the table 1 d with "D".

  To make your number a string number followed by conversion table amount works well.

• go to the next iteration of loop for and continue execution of the previous iteration

  Hello everyone,

  I want to run a loop with an offset to each iteration. I explain: I want to run a task multiple times (for loop), but with a variable delay in each iteration.

  Thus, if we put t = 0 before you run the loop and I use 3 iterations. I put a writ of execution to the first ieration after 3 sec then skip to the next iteration of course without waiting the end of the previous iteration and run the current iteration after 1.5 s and go to the third ieration (once again without waiting for the latest iteration).

  I conclude: this is a simultaneous execution of a for loop (10 to 50) from different eras (variable time between t = 0 and each running of each task.

  The problem I found in the loop is the fact that I have to wait the end of the time delay in each iteration bfore going on to the next.

  Best regards

  In all languages, a loop iteration FOR happens AFTER previous.  However, go with the parallelized FOR loop can happen to you.

  Yes... Oh, you want to know how?  Use a shift register to keep track of your current state of the output.  Use the do not reverse the value of each iteration and write this value in your data acquisition.

• extract the data of a loop for

  Hello

  I wrote a program that controls an active supplier to increase the current from 0 to 50 A, during the iteration of 1000. This current passes through a coil and form a variable magnetic field. A Gaussmeter is used to measure the field. My goal is to register the domain for each iteration. I added the Gaussmeter initial for loop program so that I can read field corresponding to each current momentary. My problem is how to extract a table that contains fields from the loop of 1000 registered and save it. I really appreciate it if you will guide me.

  Hello!

  I understand from your code, you get the values as a string? (substring, 2 and 3 of substring substring)

  In my opinion the best way to do it without the refactoring of the code is to create a queue with data type to string. See attachments (excerpt of VI and VI contains exactly the same code but I saved the VI for the version of LabVIEW 8.6).

  For future projects, consider using the http://www.ni.com/tutorial/7595/en/ stacked (or flat) State Machine sequence Structures are really hard to understand for people other than the developer.

  It is always much easier to share code that uses excerpts from VI http://www.ni.com/tutorial/9330/en/

• Update of the elements of the interface in a loop for?

  Hello

  I have a loop which, among other things, contains a command appendText.  It adds character to a text on the screen box.

  I noticed that instead of adding text to each iteration, he waits until the loop is completed, and then adds all the characters.

  It is not noticeable on short, but very sensitive loops on the longest.

  Is there a way to flash update the text box as each iteration happens, rather than dump all the text added to the end?

  Thank you guys.

  Shaun

  Two things:

  1. If a loop is running that cannot do anything else

  2. the screen redraws occur once on each image

  So if you want to add text and to see the result before adding another text, you must do this on each image (i.e. on the enterFrame event). If you try to do this in a loop, Flash runs the loop at the end first, then go to the next section, then redraw the screen to display the final result.

• 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.
