Implementation of the shift from table register

• Implementation of the functions of table (indexOf, lastIndexOf, removeDuplicates...)

  Hello

  I'm trying to implement some functions to manipulate tables more easily, as I would with other programming languages (Array.IndexOf exists in Javascript, but seems to be absent from ExtendScript).

  First of all, I tried to add these functions using Array.prototype; Here's what I've done for two of these functions:

  Array.prototype.indexOf = function (value)
          {
            for (var i = 0;i<this.length;i++)
              {
                  if (this[i] == value) return i;
              }
              return -1;
          }
         
  Array.prototype.removeDuplicates = function ()
          {
              var removed = [];
              for (var i = 0;i<this.length-1;i++) {
                      for (var j=i+1;j<this.length;j++) {
                          if (this[i] == this[j]) {               
                              removed.push(this.splice(j,)1);
                          }
                      }
                  }
                  return removed;
          }
  

  It seemed to work fine, but I discovered that it breaks this kind of loop:

  for (var i in array) {
       alert(array[i]);
       }
  

  The loop through the values in the table and continues beyond array.length with the features added to the prototype.

  As explained here, I have found a workaround, using Object.defineProperty () rather than implement functions in Array.proptotype

  Object.defineProperty(Array.prototype, "indexOf", {
    enumerable: false,
    value: function(value) {
        for (var i = 0;i<this.length;i++)
              {
                  if (this[i] == value) return i;
              }
              return -1;
      }
  });
  

  But... Object.defineProperty () is missing in ExtendScript too!

  I don't know what to try next... Any idea?

  Thank you!

  The primary reason that some of these functions do not exist, is that ExtendScript is based on the ECMA-262 standard. Very old JavaScript and I don't think all this is implemented.

  PG. 3 of the CS6 script guide (only written comprehensive guide Adobe has for the moment) after effects Developer Center | Adobe Developer Connection:

  The ExtendScript language

  "After Effects scripts using the Adobe ExtendScript language, which is an extended form of JavaScript used by several applications Adobe, including Photoshop, Illustrator, and InDesign. ExtendScript implements the JavaScript language according to the ECMA-262 specification. The After Effects script engine supports the 3rd edition of the ECMA-262 standard, including its conventions of notation and lexical, types, objects, expressions, and statements. ExtendScript also implements the E4X ECMA-357 specification, which defines the access to the data in XML format. »

  Even though I know that many developers have made prototyping, I found it to be annoying personally, especially if your code moves outside your machine. I just made autonomous functions for all my scripts. It has been easier to reuse code and create some (not all) missing features that would be nice to have the day current Javascript.

• Load the data from table to table index

  Hello

  We need to load index per table to table data. The code below works fine.

  declare
  query varchar2(200);
  Type l_emp is TABLE OF emp%rowtype INDEX BY Binary_Integer;
  rec_1 l_emp;
  
  begin
  query :=' SELECT * FROM emp';
   EXECUTE IMMEDIATE query BULK COLLECT INTO rec_1 ;
  
  For ALL  i   in rec_1 .First .. rec_1 .Last
  Insert Into emp_b
          values rec_1 (i);
  end;
  /
  

  But data from the source table and the target table are dynamic.

  Ex:

  In code, above table emp (source) and target is emp_b are static.

  But for our scenario is dependent on the source table, target would change as below.

  If source is emp target is emp_b

  If source is emp1 target is emp_b1...

  create or replace procedure p(source in varchar2, target in varchar2)
  as
  query varchar2(200);
  source varchar2(200);
  Type l_emp is TABLE OF emp%rowtype INDEX BY Binary_Integer;
  rec_1 l_emp;
  
  begin
  query :=' SELECT * FROM ' || source;
   EXECUTE IMMEDIATE query BULK COLLECT INTO rec_1 ;
  
  For ALL i   in rec_1 .First .. rec_1 .Last
   execute immediate 'INSERT INTO ' || target || ' values ' ||rec_1(i);
  end;
  /
  
  
  

  His throw. How to implement this scenario... Please help with that?

  No particular reason to use to COLLECT EVERYTHING & BULK here? Why not ordinary

  INSERT INTO target
  SELECT * FROM source;
  

  However if that's what you need you need a dynamic PLSQL block, which comes with additional side effects (code SQL injection). Dynamic SQL is not here.

  Kind regards

• The shift from collection to function error

  Hello world.  I am a novice in PL/SQL and I get an error and I don't know why.  Here is my code.

• The queue from table question

  I had a recent application where I wanted to take 100 samples of something then get the RMS of the dara. This is happening in a loop, and until the end of the program. Very basic stuff.

  • Method of the QUEUE:
  • Get queues with max 100 items.
  • Queue data (data arrive on every 50mS).
  • Get the status of the queue when the number of items is 100...
  • ... Empty the queue and get all the items (which of course will be a prison guard) and use the RMS funtion.
  • Repeat

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

  • TABLE method:
  • Initialize the array with 100 elements of the DBL 9999.99 (it is a value that can only happen in the data)
  • Insert data in the table to help replace a subset of table
  • When 100 index isn't 9999.99, then...
  • ... Put the table in the RMS function, then re - initialize the full array of the 9999.99
  • Repeat

  My questions are, who should be faster, including better management of memory?

  Thank you!

  Why not just use the RMS PtByPt VI. In this way, you don't need to store data at all? This may require that marginally more calculation, but will require less memory.

  If you insist on the pad, I'd probably go with the table for simplicity. I think you can simplify your system to determine when to treat well. No reason to have all these 9999.99 is here.

• Error 1 Configuration live while Refnum through the shift on Mac register

  All,

  I use LabVIEW 2013 SP1 with Mac OS X (Mavericks). I have a simple travel registry VI which initializes an .ini file reads/writes and closes. I did this time a lot on windows without problem. I wrote a quick VI on Mac and I get error 1. I can't understand what the problem is. I enclose my VI. Can someone shed light on this issue please?

  Sk8 says:

  When I this VI as part of high level VI, this problem occurs. It almost seems like when I run it standalone, file refnum is released - weird, but that's what happens.

  I saw that on Windows as well.  EI only really works if there is a VI call it keep the memory.  I thought that you had problems with it, with an appeal VI.  What you describe sense here.

  Keeping the AE in memory is not enough! The Top level VI, whose hierarchy is running the case open Config needs to stay active (eg. will not idle) as long as you want the configuration open to stay valid. The underlying object where configuration information is stored in a queue, and it's a refnum as no matter what other refnum in LabVIEW. And all real refnums in LabVIEW (except possibly the VISA ones) will be closed as soon as the top-level VI in which the refnum hierarchy has been created/opened going inactive (stops execution).

• Increment of the counter without using the shift register

  Is there a way to count = count + 1, with using a node registry or feedback shift?  I have a structure of the event within a while loop (see table).  When the button is touched (kickoff event), a test is carried out.  Based on the test in the case of a string is passed outside of the event to a case statement of success/failure.  The user can run one of these 'events' as many times as he or she wishes.  And in an order any... Test1 (fails)... test 1 (fails)... again... test1 (go) again... test 2 (pass) then test 1 (pass).  When the stop button is reached, I would like to know how many times each pass/fail is produced for each test.  Try to stay away from shift registers, as I have 18 w key so a possible failure for each, so I would need 36 shift registers.

  In my example, the printed final statement would be:

  TEST PASS/fail # x test was performed

  test1 failure 1

  2 in case of failure test1

  Test1 pass 3

  Test2 pass 1

  4 passes test1

  etc.

  You can use a shift register to store a table.

  Each button would be mapped to an array index. For each button pushed you the value of the index table, + 1, replace the array element and pass out back for the shift register.

• Why do I only a part of the graph of the wave even if I added the whole wave using the shift register?

  It seems only to read 200 samples and then stop. Shouldn't get a chart to continuous wave after using the shift over a time register loop?

  You must remove VI begin to break out of the loop...
  You can not 'start' a task that is already running...

  You also remove the VI start completely from your code... If you do not use start VI, a measurement task starts automatically when executing the DAQmx reading VI.

• Shift to read register previous integer table

  Hey people,

  New LabVIEW here ask about changing registers. I went through the tutorials and trying to find as much help as I could before posting, but I think that I understand not the functions of register shift as clearly as I should. I need to read integers in an array and operating some kind of new-old situation read the difference in action between two positions of stepper motor. I've attached a picture of what I have now, of course, does not work. I'm looking for any suggestions or corrections to my logic.

  Altenbach says:

  • I think you want to autoindex the blue table and use only a shift with a single output left register. Now, you get the current element against the autoindexing tunnel, which you can subscribe in the shift on the right. In the next iteration, you get the following value against the autoindexing tunnel and the previous value of the shift register, etc..

  Here is an example of this suggestion.

  

• replacement for the shift register chart

  Hi, I have a problem with my program. When I want to compare graphic legend with my present graphic it just overwirite with my graph.when this I add new data and then run my program it does not work. I tried to use shift regoster but my program eror. where should I put the register shift in my program? Thank you

  The shift register is on the outer loop. There is no need for inside while loops. The shift register should contain a table of two parcels of xy. Replace one of the accrding of two plots to the key using "replace the subset of the table".

  You don't need to a simple shift register, you have far too much code.

  (Please attach the screws with a suitable name. My Downloads folder already contains dozends of files "x.vi no title")

• How to program the shift register to play only when a new user is detected user?

  Hello

  I'm currently developing a program of position control in labview. The program is quite simple, in which case the user will enter the distance on which he wants the table in the labview program and labview will send the signal to move a motor that will turn a ball screw to move a table horizontally to the targeted position. The criterion is that the profile of the engine depends on the distance to move, if a biphase (acceleration and deceleration) or three phase (acceleration, steady speed, deceleration) to reach the position of the target.

  The problem occurs when the user wants to enter a new entry second position) for the table, as the input by the user is the position that the table should be, but the necessary input to determine what profile the engine follows depends on the distance that the table moves to the target position. Therefore, I need a function to save the entry by the user temporarily and reminds that when a new user input is detected. Hereby, I would be able to use the difference of the input (input [n + 1] [n] input) and animal feed to determine what profile the engine follows and the entry by the user can be kept in the position he wants to the table to get (to compare with encoder).

  I thought to use for shift registers do, but I am not able to perform the deduction ([n + 1] - [n]) only when it detects a new entry. When I try to use registry to offset, it moves to the target location, and we only reached it will go to the original position. For example, when a user entry 90, this means that the table must be moved to the point 90. The shift register is initialized to 0, it will move to the point 90 (90-0 = 90), but arriving at 90, the shift register sends a signal of 90 (90-90 = 0) and the table back to its original position.

  Is it possible that I can delay the reading of the shift register only when a new entry is detected or there at - it another way for me to achieve what I want?

  I tried searching the forum site and neither discussion but could not find similar problems. Thank you for your help in advance.

  As I understand it, the use of shift registers with a structure of the event (to detect a user event when the user enters a new value) should solve the problem. Do not forget to post your request (or a version of it that isolates the issue) when you arrive at the lab, if we can get a clear visual of the issue you are facing.

• Change the shift register

  I hope someone can direct me on that. I'm stuck.

  The NTC, I want that it start at zero, enter the nested loop

  and when the case statement is equal to one, add 3000,

  so I have a lag on "undesirable" elements in the 1 d

  table I'm parsing...

  TIA!

  the nested loop shift register is not initialized, it is best to initialize it with a constant 0

  Then, the index entry Array subset function is connected after or before the function incriment? I can't decide...

  in any case, if it is connected before the incremint function then the nested loop iteration 1 will send a 0 at the entrance to the function of the subset of the Array index.

  EWW! , a lot of entries, words of functions in the above paragraph lol , can u get me here?

  now I can just understand the problem what exactly you're talking about. the sequence of events for your code will be like this:

  After the nested loop is complete, the output will be available (1 d the function add array element table) to the structure of the case where you want to add 3000 to the value of the shift register and start the loop nested with initialized again records with value = 3000? Am I wrong?

  If I'm right, you must reset the shift by using a control register, create a local variable to him and place it in the business structure then her manipulate it as shown below:

  

  Since the default data of "N" type digital command value is 0, then initially the shift registers will be initialized with 0 as the guy above

• initialize the shift register

  Hello

  How to initialize the shift register (inside the second loop for) so that it starts from 0 whenever the program runs. I tried to attach a constant 0 in left shift register, but which resets the registry whenever it passes through the inner loop.

  Thank you

  If you only want to reset once at the beginning and not for each iteration of the loop for external, you must add another register to lag on the outer for loop and wire lag 0 to that registry.

• 'shift' key does not work in the multiple selection table

  I created a table by dragging default datacontrol vo, the multiple value RowSelection, override the SelectionListener a manageBean method as follows:

  Is there a way to fix this? Thank you...

  for rowSelection multiple = to work with 'shift' you should not have the selectionListener or selectedrowkeys for your af:table
  http://www.adftips.com/2010/11/ADF-UI-implementing-multi-select-table.html
  delete selectedrowkeys and ownership selectionListener in the table and you will get select using the 'shift '.
