  Well, there are several possible solution. Do you think all the elelemts that are not in the course of exit or do you only each. For example, if the table contains 3 of the same element, do you want twice in the double output?

  I suppose you want only there once, so just the existing code to scale accordingly. See attached example. If you want all, remove the internal node of case and research and blindly add all items in doubles.

  Note that there is full of the most effective ways to do this, but the current code is sufficient for small tables.

• How to add events to the array elements?

  Hello.

  I have the table with 5 boxes.

  I show as boxes on the stage that + having shown that it is random.

  Now, I want to add events to this boxes.

  For example if I click for box1 I have to go to "p4", if I click to other boxes that I have to go to "p3".

  I'm trying to do the same thing as for the buttons, but its does not work:

  classNames[0].addEventListener(MouseEvent.CLICK, goCorrect);
  function goCorrect(event:MouseEvent):void {
       trace("p4");
       gotoAndStop('p4');
  }
  
  classNames[1].addEventListener(MouseEvent.CLICK, goWrong);
  function goWrong(event:MouseEvent):void {
       trace("p3");
       gotoAndStop('p3');
  }
  

  All the code in the code here:

  var classNames:Array=["box1","box2","box3","box4","box5"];
  var boxesList:Array=[];
  var ClassRef:Class;
  
  for (var i:int = 0; i < classNames.length; i++) {
       ClassRef=Class(getDefinitionByName(classNames[i]));
       boxesList[i] = new ClassRef();
       addChild(boxesList[i]);
  }
  
  var currentBox:MovieClip;
  
  
  var nextX:Number=0;
  for (var iii:int = 0; iii < classNames.length; iii++) {
       currentBox=boxesList[iii];
       currentBox.x=nextX;
       nextX+=currentBox.width;
  }
  
  
  for (iii= 0; iii < 1*boxesList.length; iii++) {
       var pos1:int = (Math.random()*1000) %boxesList.length;
       var pos2:int = (Math.random()*1000) %boxesList.length;
  
       if (pos1!=pos2) {
            var temp:int=boxesList[pos1].x;
            boxesList[pos1].x=boxesList[pos2].x;
            boxesList[pos2].x=temp;
       }
  }
  
  myBox1.visible=false;
  
  
  classNames[0].addEventListener(MouseEvent.CLICK, goCorrect);
  function goCorrect(event:MouseEvent):void {
       trace("p4");
       gotoAndStop('p4');
  }
  
  classNames[1].addEventListener(MouseEvent.CLICK, goWrong);
  function goWrong(event:MouseEvent):void {
       trace("p3");
       gotoAndStop('p3');
  }
  //box1.useHandCursor=true;
  

  You cannot add event listeners to the objects that send events. Generally speaking, an object that you want to send events should extend the EventDispatcher class.

  In your case, you add event listener for the classNames group members that are strings. String not to send events. So, you have to add listeners to events for objects that you instantiate while loop if classNames - these items are (I presume that these are instances of MovieClip, which stretches from EventDispatcher). Therefore, in your case, you can do the following:

  MovieClip(boxesList[0]).addEventListener(MouseEvent.CLICK, goCorrect);function goCorrect(event:MouseEvent):void {     trace("p4");     gotoAndStop('p4');}
  
  MovieClip(boxesList[1]).addEventListener(MouseEvent.CLICK, goWrong);function goWrong(event:MouseEvent):void {     trace("p3");     gotoAndStop('p3');}

  the labview vc and program project are attached.

  the problem is: run the program labview, can not get the good result of the table

• How can I view all the elements of an array?

  Hello

  I'm learning about the handling of tables.  The example finder includes this one, 'build array_forum.vi', which shows the two modes, concatenate and adding, I understand, HOWEVER, I can't understand how they built this vi.  For example, I can find the Array function to build, but I do not understand how they created the "digital data table 1" "data table 2" digital... etc, and I can't find the functions on the pallets that cause display "build the CONCATENATE entries table". ".  Where are these blue functions?

  Where these functions are found in the palette, and how we build them like that?

  The other vi indicated here, 'for loop array_forum.vi' is my attempt to reproduce, but it doesn't show all the elements of the array; However, it only displays a SINGLE element, the last element of the array.  How can I view all the items in the table I am creating using the FOR LOOP?

  Thank you

  I think I posted this in the wrong place.  I reposted it on the forum of Labview.

• allocation of an array of 2d in labVIEW and move to the DLL function to obtain data

  Hi all!

  I searched a lot about this, but one cannot find any solution. Please find attached the vi that I try to get a unit of 32 channels data,

  100000 samples per channel with 14-bit resolution. And please also find enclosed the header for my dll file. (in the header, it is the GetBuffers function).

  There is not a lot of data, it is a little more then 6 MB in the task of LAbVIEW Manager eats about 30 MB more memory, then it should. Are there explanations why?

  Because there is much more data in a single channel (million samples or more)

  Then I will try to allocate a 2D to data array, but when I try to run my LabVIEW vi crashes.

  Could you please help?

  Best regards

  Tomzi

  Dear Tomzi!

  To allocate the data in a table in LabVIEW, you must always initialize, as in a you must have a valid entry on cell (x-, y - 1) have a size of table of (x, y). It is usually best to use the function Array initialized for this purpose.

  There are ways to pass arrays 2D to DLLs, cand find you examples of both in examples > communicate with external Applications > external Code using the > integrating DLLs > DLL.vi call. Basically, LabVIEW can pass in the form of a big table 1 d 2D tables, so you'll need to spend too much table size index it. If you pass the array 2D handles it is preferable to use the typedef that LabVIEW generates for you, something along the lines of

  / * LabVIEW created typedef * /.
  
  typedef struct {}
  
  	Int32 dimSizes [2];
  
  	Double elt [1];
  
  	} TD1;
  
  typedef TD1 * TD1Hdl;

  I hope this helps.

• What is READ the array returned by the DAQmx meter? How can I know the two functions DAQmx READ data stream in the same WHILE loop?

  I have a question about the order of execution.  In the WHILE loop, I have two things to measure, period and tension using the DAQmx READ functions for voltage and the meter.  In the end, I want to collect these data as points almost simultaneously as possible, as a pair and then send them together to another piece of code (not shown here) which them will result in some sort of command for an engine.  It would be run, and then I want to perceive the tension and the period at a time later and do the same thing.

  (1.) I'm a little confused on what the meter of the READ function is back because it's a table.  What is a picture of?  I thought that it was up to the value of the individual periods between rising edges.  The output of the counter 1 DBL d's a table. How many elements in this table, and what determines the size of this table?  Are the elements of the array the individual delays between the edges?  How many values are stored in the array by executing?   We take the AVERAGE of the last 15 items, but do not know if we are throwing some of the data or what.  How to understand the composition of this painting?  How can I change the composition of this painting?  Is it possible to measure only one period at a time, for example the time between TWO edges?

  2.) Will this WHILE loop execute as it gathers tension and a "period table ' (remains to be understood by me) by TIME running in a loop?  In particular, we want that the value of the tension associated with the value of the AVERAGE of the period "array", so we can use two data items to create orders of next control every time that the two values are reported.  The structure for the delivery of vi will be attached data in pairs like this?  I understand that one of the READING functions run not before the other function of READING in the WHILE loop.  I want that the period "means" and "strain (Volt) collected at the same pace. This vi will he?

  Thank you

  Hi David,

  I suggest including the DAQmx Start Task function. If it does not start before the loop, it starts the loop and work very well, but it is not as fast and efficient. In the model of task status, task wiill go to run the checked each iteration of the loop and then back the time checked running when it restarts.

  The status of the task model: http://zone.ni.com/reference/en-XX/help/370466V-01/mxcncpts/taskstatemodel/

• How to case statement based on the array of values of 3 or more?

  I'm trying to figure out how to do a comparison or case structure... based on the creation of an array of boolean 3 (or maybe more).

  I have a table (it's from a serial connection, and I am conversion back to a table to work with) [t, F, F] in this case I would like to display on a status indicator "STBY".

  If the array is defined on [F, T, F] I want to display in this indicator "ON".

  If the array is defined on [F, F, T] I want to display in this "EMPTY" indicator

  I can not understand how to compare combinations of things... I read in an array of bytes, and the first 3 bits in this example, determine what to display in a status... I can't figure out how to do with structure case... or without some channels to research and/or bad comparison...

  Any suggestions?

  Thanks in advance,

  Cayenne

  You can use search 1 d array and find the first real.

  Or you could convert the table of Boolean integer U8 and integer that results to determine which cases to run.  (4, vs, vs 1-2)

• How to add information in the body/attachment email with labview

  Hi, I did a project on the development of a game for seniors. It's something the breaker of brick where the elderly can adjust the size of the ball & speed. The game worked perfectly.

  If it works that way, when I press the button 'Quit' in the game, he supposed to send an email to the caregiver to notify him that the elderly have played the game. And it works.

  But now I have to include more information in the email, for example how fast & the size of the ball, that the elderly were adjusted during the game. Can someone help me on how I should actually Merge the information 'speed & size' adjusted during the game in the email which is supposed to be sent to the caregiver.

  Thank you.

  It's strange. You have said that you are new to LabVIEW, but wrote this program that has structures of the event, parallel loops, queues, manipulation of the 3D image,... and you don't know how to pass the values of two controls a string in a Subvi?

  Size and speed are controlled by the two sliders on the front panel. When you leave, just read their values and forms a chain that you pass in the Subvi email as the body of the message. Your Subvi e-mail already has a mastery of the body on this subject, but it is not connected to a Terminal. You have just it has a default value.

• How to read the size of the array, eliminating empty values

  I have an array of size 2 X 10. In the first column, the elements are 10 and in the second column, the elements are only 6. If I use the size of the array and the size of the second column of the index, the value given is 10 which is supposed to be 6. I noticed that it creates null or empty values in the column for the other four. How can I eliminate empty values, and only get the real sze of the column?

  The column in the index and use search 1 D table for an empty string.  The result should be the number of non-empty strings.  If the result is - 1, use the actual size of table.
