control array element changing order

• Change the value of the array element without using the keyboard

  I have a control array on my front, say 1 d, 10 items.

  In addition, the front panel should be used with a touch screen, so I have a Subvi keyboard that should be called when I choose one of the elements of the array.  Therefore, no keyboard entry is allowed.

  My question is, how can I determine which element that the user hit/clicked?... .and how to change this value?

  -Mike

  Gents nevermind, found a way to emphasise that if this is the best way, but I got it.

  In my structure of the event, I have an event looking for the mouse event down in regards to the control array.  This event triggers my screen touch keyboard Subvi to fire, and the closure of the Subvi I pass its value to the ArrElem.Value property to assign the table a hit/clicked item.  Works.

• array element references confused me

  Then... I'm playing with references to arrays, specifically references to items in a table.

  It seems that I should be able to read the value of the table, but because of how I am tying TestStand and LabVIEW, I am trying to create a utility that automatically obtain data back between the LV and TS, where the types of data passed back are completely unknown and, possibly, paintings of beams that have tables nested clusters.

  I try to walk the LV data structure and reference TestStand and get the right data.  However, I can't seem to be able to use references to point to specific elements of a table - see example I expect the high and the low code works the same, but they do not.

  Any suggestions on what I do wrong to get the top and bottom to work the same?

  Is not a way to get or set the value of a specific array element.  To set a particular array element, you must use replace table subset.  To get the value of a particular array element, you use table to index.

  Indexvalues property node is used to determine which is the first item that appears.  It changes the value of the indexer the upper left corner of the table.

  One thing I noticed that I don't know if I knew before, it was this setting the property value on the reference of array element, node will have an impact on the first element of visible table.  If you turn the highlight performance and play with array index, while it is running, you will see that the resulting table will be different.

  Although it IS possible, you can not do after seeing what it takes.

  We can get the value of an array element that is in a control or indicator provided it it the upper left display element.

  This nugget exploits that factand see how it can be done. Note: I have not tested this code lately so I don't know if NEITHER broke this behavior since the writing of this nugget.

• Reference to the array of Clusters with an array element

  Hello

  I have an array of clusters of CONTROL (qualifying as "upper-tier cluster table") with one of the items is an array of cluster cluster (see attached).

  I intend to "reference" of this cluster of high level at different screws (as add item VI, insert item VI, delete the item VI etc.) and access (add/edit delete) the elements of this array.

  

  In my code, how I cataloged the array element (cluster) on the cluster internal (as shown on the figure)?

  I use LV RT on PXI.

  

  Hello smercurio_fc,

  Thank you for your example! Just a question: actually, with shift registers, is an example of creating a local copy of the full range? Even if the value of the lowest level cluster is changed, is the complete table is updated at the end (registry value to offset the full picture at the right end is updated using the reference node and property)? This VI will be slow when the size of the array becomes great?

  Comment of nicely.

• The callback functions control array?

  My apologies for my basic question.

  I'm experimenting with control arrays and so far able to collect data in controls of a string that is contained in the tables of controls.  Works well.  Of course, none of these controls need callback functions.

  Now, I need a few momentary controls in a control array as well.  So my question is, should I use a single callback for all button controls function in this unique table?  And if so, how can I do to determine which element in the control array called the function?  Reading the forums, it seems as if the use of the data parameter of the callback could happen to me.

  I just wanted to ask before we get off the track.  Thank you!

  Yes, callbackData can be useful in such a situation, but if you can limit to switch to array index to distinguish what to do the recall of your button might be something on this line:

  int CVICALLBACK BtnAttayCallback (int panel, int control, int event,
          void *callbackData, int eventData1, int eventData2)
  {
      int    handle, index;
  
      switch (event)  {
          case EVENT_COMMIT:
              handle = GetCtrlArrayFromResourceID (panel, control);
              GetCtrlArrayIndex (handle, panel, control, &index);
              switch (index) {
                  // Your code here
              }
      }
      return 0;
  }
  

  (No CVI install here so I can't test it: check the code, but it should work reasonably)

• How can you specify the default value for the undefined array elements

  According to aid LV, the tables have two default values, the normal default value and the default value for the undefined array elements.

  I assume that there must be a way to specify the default value for later, but I can't find it anywhere.  Any ideas?

  I know that you can drag the item out of the table container.  Change the default value on this scalar element.  Then drag the item in table tank.

  How to put the names of programs in the control panel in the order of the alphabet

  Hi maguma,.

  Please use the Microsoft Windows Forum.

  When you go to Control Panel , click on "view by" at the top right of the screen and select 'large icons or small icons' , she will change in alphabetical order.

  If you are referring to the programs and features in Control Panel, you can right-click in the empty space of the programs and features page > click on 'View' and click on 'Name' , IT ' l be alphabetical.

• read part of an array element

  Hi all.

  As indicated in the title, I'm reading part of an array element.

  What I'm doing is reading a LeCroy scope values using a 'write' 'read' I returned the values in a table, but the question is the scope returns a value of "1, 52.33E - 3".

  I just want the element to be 52,33 so I can use it for other calculations.

  For example, my table.

  ' 1, 34.334E - 3.

  ' 1, 53.343E - 3.

  ' 1, 143.232E-

  And I want it to be

  34.334

  53.343

  143.232

  Thank you!

  Use string functions (match pattern) to find the comma. Then convert the part after the comma to a number using the string appropriate to the Number function.

  Are throwing you what looks like an exhibitor intentionally?

  The last string seems to miss the exhibitor. This suggests you may have problems with your communications with the instrument.

• Get all the different values in a table - 'or array elements' does not work with I32

  Hello

  I just found out that "array elements or" does not work with a table 1 d of integer values. I didn't expect that.

  I did a semi quick forum search and did not find a pointer to an effective solution. Can someone give me a hint?

  Do not back my initial intention is to list all the values that appear in an array of integers.

  I thought that if I converted the figures for powers of 2 and or I had solved the problem at hand - only to discover that the elements of array does not.

  If someone could propose a different approach, I'd be happy too.

  I should mention that the execution time is a factor here - I need a fast code, but any suggestions are welcome because they could help me get started.

  Best regards Florian

  Hi Florian.

  try this:

  

  "Function, it seems, the table of GOLD ' is polymorphic (as written in the context-sensitive help), but does not support arrays of I32. At least the error message means just that...

• How to use control arrays

  Is there a tutorial on how to use control arrays in LabWindows?

  It is quite simple to create in IUR, but the coding is not what I was hoping.

  I tried this

  for (iLoop = 0; iLoop = iNumberofControls; iLoop ++)

  SetCtrlVal (Panel, CRTLARRAY [iLoop], value);

  Hello

  I am aware of the manual, http://zone.ni.com/reference/en-XX/help/370051T-01/cvi/uiref/programming_with_control_arrays/and the userint\ledctrlarray.cws (very) brief example

  In general, you must balance only Min/max property, then you can "zoom and Pan" by program:

• Control arrays disappear when closing the window .uir

  Using LabWindows/CVI 2010, I created a program of simple test with a panel containing a couple of buttons push, three tumbleurs and three control LED. I can create arrays of controls containing the toggle switches and/or LEDs in the .uir editor and access in the program, but when I close the .uir editing window and reopen the .uir file, control arrays are gone from the .uir file and of course when I rebuild the program I can't access it. This happens if I leave LW/CVI entirely or if I just close the editor of .uir. If I explicitly the file .uir after creating tables, everything seems fine, but then when I close the .uir window I see an asterisk briefly appear in the tab of the file name, as if it is modify the file, and then re-register on the goal.

  I can duplicate this just creating one or two control panels and by closing the window. Sets disappear, even though I explicitly save the .uir file after I created them. Is there something I can do to prevent this?

  Thank you

  Brian

  Brian.

  It seems that your UIR may have have been saved for an earlier at some point.  If you open the UIR and look in the lower right corner, you say 'file UIR 2010'?  "Otherwise, you need to click on File ' Save *.uir as and save the UIR under a 2010 UIR.

  

  If you choose to save the IUR for an earlier version, CVI remembers this decision and always saves the IUR for than the previous version.  You will have to explicitly choose to save them for the current version.

  Let me know if this does not fix things for you-

• A fundamental question/problem with the like undefined array element

  Hello everyone,

  Thanks for looking at my problem. I am very new script and javaScript, and I encountered a strange problem. I always try to solve all my problem myself, with documentation (it helps to learn) or as a last resort with the help of google. But in this case, I'm stuck. I'm sure its something very simple and elementary.

  Here I have a code that simply loads a text file (txt), load the contents of the file in a "var glad." This summary text file a font family name, every name on a new line, as:

  Albertus

  Antenna

  Antique

  Arial

  Arimo

  Front

  Barber1

  Barber2

  Barber3

  Barber4

  Birch

  Blackoak... .etc

  Now I hollow the variable content of loop, extract each letter and add it to the list '[i]' table. If the character is a line break the list [i] table adds another element (i = i + 1); That's how I separate each name in its own element of array.

  The problem I encounter is, when I have hollow loop table fontList and $.writeln (fontList [i]) is the result in the console :

  undefinedAlbertus

  undefinedAntenna

  undefinedAntique

  undefinedArial... etc.

  I don't get serious, where the undefined comes? As far as I tested each digit to be added to the array element, I see nothing extraordinary.

  ----------------------------

  ----------------------------

  Here is my code:

  #target illustrator

  var doc = app.documents.add ();

  Open the file

  var myFile = new File ("c:/ScriptFiles/installedFonts-Families.txt");

  openFile var = myFile.open ("r");

  check if it is open

  if(OpenFile == true) {}

  {$.writeln ("the file has loaded")}

  else {$.writeln ("the file does not load, check the name or the path") ;}}

  load the contents of the file into a variable

  var content = myFile.read ();

  myFile.close ();

  var ch;

  var x = 0;

  var fontList = [];

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

  ch = content.charAt (i);

  If ((ch)! == (string.fromCharCode(0)) (10))) {}

  fontList [x] += ch;

  }

  else {}

  x ++;

  }

  }

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

  $.writeln (fontList [i]);

  }

  doc. Close (SaveOptions.DONOTSAVECHANGES);

  -----------------

  -----------------

  Thanks for any help or an explanation. If you have any tips on how to improve my practices or any suspicion, please do not hesitate to say. Thank you

  Hi vladac54380629,

  better, you try something like this:

  #target illustrator
  
  //var doc = app.documents.add(); 
  
  //open file
  var myFile = new File ("c:/ScriptFiles/installedFonts-Families.txt");
  var openFile = myFile.open("r"); 
  
  //check if open
  if(openFile == true){
      $.writeln("The file has loaded")}
  else {$.writeln("The file did not load, check the name or the path");} 
  
  //load the file content into a variable
  var fontList = []; 
  
  var content = myFile.read();
  fontList = content.split ("\n")
  myFile.close(); 
  
  for ( i = 0; i < fontList.length; i++) {
     $.writeln(fontList[i]);
    }
  
  //doc.close (SaveOptions.DONOTSAVECHANGES);
  

  Have fun

  A note:

  The real font names may be different from your own list for example:

  Arial! = ArialMT

  Birch! = BirchStd

  Blackoak! = BlackoakStd
