• How to create parallel tasks using parallel for loops

  Hello

  I'm going to put in place a program that communicates with the six logical controllers and must read the status of the system every 100 Ms. we use OPC datasockets for this, and they appear a bit slow.

  I created a uniform method of comm. for all controllers, and now I find myself this method of programming six times to communicate with each system. I was wondering if it could be done more elegant using the parallel for loop, in which case I program an Exchange once and then six workers running simultaneously. Since a picture is clearer than a thousand words, what I'm asking is:

  Is it possible to replace something like

  

  by

  

  and that for performing these tasks in parallel loop (on different cores / in different threads)?

  I have configured the loop to create instances of the 8 to the compilation, so I would 2 surplus available when running instances if I find that I need an additional system.

  The benefits of the Show method in the second photo for me are:

  * takes less space

  * changes need be made only once

  * less blocks, son and other things makes it clearer what is happening.

  * flexibility of the actual number of tasks running (8 available runtime instances)

  * If multiple tasks are necessary, I need only update the maximum number of instances and recompile, i.e. no cutting and pasting necessary.

  Unfortunately, I don't have these available system yet, so there is no way to test this. Yet, I would like to know if the above works as I hope - unfortunately the help of labview is not quite clear to me on that.

  Best regards

  Frans, the parallel for loop will work as expected in this situation. The six tasks will run simultaneously in different threads. What part of the aid could be made clearer?

• How can I replace a damaged Adobe Photoshop Elements 9 Editor?  I've used this for years and all of a sudden his damaged.  I do not have the CD - can't find it - just moved.

  How can I replace an editor Adobe Photoshop Elements 9 "damaged"?

  I have been using this program for years and all of a sudden - its damaged!

  I have not the CD more if that's how I got it in my Mac.

  I tried to retrieve the serial number through Adobe, but... the account I "had" with Adobe for years has been under a name of ID that I don't remember years ago.  None worked.

  I therefore restored a new account to be able to communicate with Adobe with this name for what to do.

  So, what should I do?

  I need this program.

  You can download the installation program:

  Your serial number issues will have to be developed with support, so call them.

• Extraction of 2 x 2 table from 10 x 10 array using only for loops

  Hi all

  I have this assignment for "pattern matching" - user enters the Boolean model 2 x 2, and I have to compare and find in the bigger picture of Boolean random 10 x 10.
  I managed to do it with the table palette, but my instructor alert me that for this mission we prohibit this Palace and don't use the "basic" functions
  So I'm trying to track my solution and accurate table 2 x 2 from the big picture, but I fall into the "well-known" problem with loops like I can see while searching in google - I want the loop will depart from different 'i', this allows to extract all tables to another place of the largest array iteration 2 x 2.

  any help is appreciated,

  
  

• How to use a FOR LOOP to create multiple forms?

  I use Adobe animate CC (formerly Flash Professional CC) and I am trying to adjust the following snippet so that it creates several rectangles:

  var form = createjs new. Form (new createjs. Graphics ().beginFill("#FF0000").drawRect (5,5,100,100));

  this.addChild (shape);

  I then set it and put it in a loop I thought work in the reproduction of the form. The following code creates only a rectangle well?

  for (i = 0; i < 10; i ++) {}

  var i is new createjs. Form (new createjs. Graphics ().beginFill("#FF0000").drawRect (5,5,30,30));

  this.addChild (i);

  Move so that they do not lie on the other

  This.x += 50;

  }

  I think that the problem is how you use your iterator variable. In your loop, at the first start, i is equal to 0, then you immediately replace 0 with an instance of the Shape class, which means when he tries to loop again, I is not less than 10. They can't, because it is now a shape, not a whole number.

  Try this inside the loop:

  newshape var = new createjs. Form (new createjs. Graphics ().beginFill("#FF0000").drawRect (5,5,30,30));

  newshape.x += 50;

  this.addChild (newshape);

  A parallel FOR loop has an overhead for parallelization (split the problem, then go back the results, etc.). If the code is very fast, the overhead is proportionally larger. If the Subvi takes a long time to complete, the overhead of parallelization is insignificant. It is often not worthwhile to parallelize the loops with a very simple and fast code.

• slider with a for loop

  Hi all
  
  I have a simple slider in my pl/sql procedure. I use the method for the slider of the loop and retrieve the values below.
  
  
  DECLARE
  
  VAR_A VARCHAR2 (100);
  
  CURSOR C1 IS
  SELECT DEPT_NAME, DEPT_NO OF THE DEPARTMENT;
  BEGIN
  
  FOR I IN C1
  LOOP
  VAR_A: = I.DEPT_NAME;
  END LOOP;
  
  -etc etc.
  -etc etc.
  
  EXCEPTION
  WHILE OTHERS THEN
  DBMS_OUTPUT. Put_line ('hello');
  
  END
  
  This workfine but if the DEPT table does not all records in it, it goes directly to the management of exceptions, and if there are all the other instructions after the FOR LOOP, they will not be executed. I know there is a method to use the cursor (instruction FETCH) more, but I want to know what is wrong by using the FOR LOOP.
  
  The strange thing about this example is, even if I catch the exception, the program stops and if the DEPT table has no recording errors.
  
  Any suggestions or tips are greatly appreciated.

  the program stops and if the DEPT table has no recording errors.

  This seems a little suspicious. Probably another error product which is now hidden simply because of your manager WHEN of OTHER of exceptions, that didn't come out the real error message.

  I recommend getting rid of the exception handler together and after the release of the thrown exception.

  In the FOR loop "obj" is a pointer to the cursor/query, not a subject in its own right. It gives you just a reference in the query.

  So with that you are referring to the query, but then you need to refer to the column in the query that you are interested, so why there need a name (in my case I called it 'x'). 'x' is the object, and then you refer to the attribute of this object "text".

  In the first request that you simply select the value directly object in a variable, so no matter what it's called in the query values are returned by the position that is the first column in the query goes into the first variable in the INTO clause. Once you have that then the variable itself contains the object, and you can just refer to the attribute within that.

  Hope that makes sense.

• Oracle Business Rule - Table of decision for loop

  Hi Experts,

  I have the scenario where I get the list of values, and I don't have to iterate over the values in the decision table. I can't use the normal return If so , in reason of the restriction of customer "only use table decision." Can someone guide me how to use the for loop in the decision table?

  Thank you

  We can check multiple values of the same element in the decision table. so no need to make a loop.

• Diff between open-close-Fetch loop and For loop

  Cursor can be used in many ways. Need to know the difference between these 2 types.
  
  (1) open - close - cursor to retrieve data
  (2) because the loop open, close and then retrieves the data internally.
  
  No need to open manually, close, exit in case of loop statements For.
  
  Is there an any example where loop For cannot be used and open-close-Fetch must be used? Or any what performance advantage using Open-Close-Fetch instead of the loop For.

  If you use a Refcursor then you can't open it with the help OF the loop. You must manually open it and process. In terms of performance, I see no advantage of using a FOR LOOP on a slider of treatment manually. But using the loop looks neat and human tend to make mistake by closing the cursor when the fact at hand, but when you allow oracle to take care of her, she does it to perfection.

• CURSOR for loops or an associative array

  There are no variables to watch. Not sure if the TOAD can show these values
  
  If I had used an associative array (master_proc2 below), I can see the values stored in the table by clicking on "show Collection"variable in PL/SQL developer.

  Thank you Tubby. If you are faced with a situation where you MUST use a loop. Then you would go to associative arrays rather than CURSOR FOR loops. Right?

  Doesn't happen too often, but if/when then I would do as I said in my first post. Use the transformation, the collection table in BULK and FORALLs.

  If we use your example posted, I would NOT spend a single table (in a loop mode) value I would be transmitted in the OVERALL picture and treat it with FORALL.

  So, I would still use neither of the approaches that you mentioned.

• Would it not correct to say that the PCI-6110 can be set to 'redeclenchables' but the PXI-6115 module cannot use this property?

  Would it not correct to say that the PCI-6110 can be set to 'redeclenchables' but the PXI-6115 module cannot use this property?  If Yes, where is it documented the series cards can do trigger?  For example, is it possible to configure the trigger on the PXI-6124?

  Hi Joel_Neptune,

  The PCI-6110 and other materials as the PXI-6115 S series and SMU-6124 do not natively support NOR-DAQmx analog input alarm. However, you can use one of the generalist counters/timers of the Council to generate a reenclenchees pulse train, then use this as the sample clock pulse train. This transportation example shows how:

  LabVIEW\examples\DAQmx\Synchronization\Multi-Function.llb\Multi-Function-Ctr Retrigg Pulse Train generation for the Clock.vi sample

  In addition, the new material of the simultaneous sampling X series are supported trigger analog input without using a separate task of counters/timers.
