• Problem with creation of table of references notifier by using a loop

  Hi all

  I am attaching two try_ChannelsOn2ndMonitor.vi screws out of the random values to four graphics and ChannelGraphsOnSecondMonitor2.vi receives these values through an array of references Notifier and refers to four corresponding graphics. Essentially, the graphics in the two screws are supposed to - and do - displays the same values.

  As a first step, using a loop to create the table of references of the notifier, I was unable to get the four graphs in the sub - VI to produce the desired values. They showed only the values in Figure 4 in the main VI. I tried to use the indexing, and then I tried using Shift Registers associated with the function of 'Building the table', but none of these methods worked. Finally, the only method that worked was that you see in try_ChannelsOn2ndMonitor.vi, which was to create four reporters simultaneously and combine them using 'building the table '. My question is: why is it not possible to create the array of references notifier by using a loop and always get the correct functionality? I spent a few hours I wondered about this.

  All of the comments related to my use of the notifiers, notifying bays or the reference of VI in the Structure of sequence are also appreciated. The structure of sequence is only there because the sub VI must be taken out of a second monitor; I essentially disabled it by setting the FP. State to 'Standard '.

  Thank you!

  The table is still the order of the references notifier - so that you know the correct order.

  When you say "it will continue execution as soon as one of the notifications is received", do you know if it means he will send this notification for each registrant, or just for the appropriate warning system?

  I'm waiting on multiple notification - if you expected to return (and continue to run) once it receives all notifications I don't think it's what he does based on my understanding of the documentation.

  OK, now that I have had a good look, I probably slightly different framing the code - I propose the Subvi out of the while loop and then put a while loop around the code in the Sub - VI. Something like this:

  

  That's what I wanted to say to have individual loops for the Subvi - terminal error is connected to the judgment for loops (and thus the VI) stop running when you release the notifier. That should remove the need for static VI reference as the VI remains before the end of your first level VI - then you can move your code of positioning inside the Subvi.

  Using the sequence of structures here as you have done to make sure that the code block happens before your start of loop is very good, another common method is to wire the error out in (or at) the border of the loop - in a more complicated application, you would maybe put this code in a State 'init' of a state machine.

• Control reference 1055 error when you use a loop for

  Hello

  I'm having a problem using control references to accomplish the following: I a VI that reads data from a text file, and then uses that automatically update the value of a control on front panel on two live different, then set the default values, and then save them. Comes from the array of control references, I tried looping on text labels until I have find the one corresponding to the order, I want to change and then update its value. The problem I have is that if I use a loop for, then 9times of LabVIEW 10 complains error 1055: "LabVIEW: object reference is not valid. If instead I the wiring to the index table and manually extract the reference, then it works every time and for each index of the reference of the order.

  Can someone take a look at my code and just see if its obvious what the problem is? In this case, I have a simple solution, but I would really like to understand what I did wrong. I have included as a code snippet, but also attached the files if that helps (Its Import_Colormap.vi, which is the problem). Persons with disabilities code fails, the active code works but I can't see what is really the difference between them - I can change the index of array 0,1,2, 3. and no mistake.

  Thank you.

  

  Your "Colormap.ctl" is a strict type def that contains a ring.  You define the elements programmatically, make the default values, and then save the "Colormap.ctl"?   I was never practicing this but here is a thread that covers this in detail. I do not understand what you expect reach by running.
  The next thing: at the same time (at the same time!), you open the Colormap.vi (this is what we see in yout PNG) that contains an instance of the Colormap.ctl on the front panel. I'm not pretty sure if LabVIEW can handle this correctly. This could be the reason why you sometimes get the error 1105.
  I prefer StringsAndValues and eventually the value of the ring running.  There is no need to do it with a def of strict type.

• Using the loop

  Hi all

  I have two VO... IE, VO1 and VO2. and I have a handful of two your

  I want to compare attribute VO1 VO2 attribute... both have guess that 4 attributes.

  what I want to do here is: first of all I want to compare all 4 attributess VO1 1 rank to all the 4 attributes of 1st row of VO2. If they're all matches then the 5th value of attribute attribute value VO1 VO2 5th.

  If the 1st rank of VO1 is not with the 1st rank of VO2 then compare VO1 1 rank 2nd in the VO2... and so on...

  If the match then set value and exit that loop... and yet once compare with 2nd row of VO1 1st row of VO2...

  How can I do this... can I use 2 loops?

  loop external and inner loop?

  If Yes, then how can I extract the data of both your and how I can compare their attributes?

  Thank you...

• creation of an area of dynamic text inside a movieclip using a loop for

  I'm having issues creating several areas of dynamic text inside a movieclip using a loop for.  I use 2 ACEs.  Here is the code I've created so far

  var leading: Number = 0;

  function drawClip (): Void

  {

  this.createEmptyMovieClip ("mc", 10);

  for (i = 0; i < 5; i ++)

  {

  mc.createTextField ('text areas' + i, this.getNextHighestDepth (), 0, leading, 200, 200)

  MC ["text boxes" + i] .text = i;

  leader + a = 20;

  }

  }

  drawClip();

  Create a mc but she only display the number 5

  Any thoughts?

  You are cionstantly, crushing the textfield created previously due to the use of the wrong depth define.  You point to 'this' to get a depth value, but he planted inside 'mc', so it's always at the same depth since "this" index of depth does not change.  Use...

  mc.createTextField ('text areas' + i, mc.getNextHighestDepth (), 0, leading, 200, 200)

  Perhaps better understand everything that makes this PL/SQL loop construction.

  PL/SQL is two languages. It's PL (logic programming code) like Pascal, C or Java. You can use a 2nd language in it called SQL. The PL engine will be able to recognize when the 2nd language is used. And it compiles all the things that are necessary for motor PL call the SQL engine, pass the data to the SQL engine and get back data, etc. (compare this with the complexity of the use of SQL in Pascal, C or Java language).

  So what's this loop? The PL engine recognizes the SQL SELECT statement. It creates an implicit cursor by calling the SQL engine to analyze (I hope a soft Parser), then run it.

  As part of the loop of the PL, the PL engine now calls the SQL engine to extract data (lines) of the cursor. With 10g and later, the engine of the PL is smart enough to use the implicit treatment in bulk.

  Before 10 g that he used to extract a line from the SQL engine, make the loop, the next line extraction, the loop, etc. In other words, if there is a 1000 lines to pick up, he'll call the SQL engine after 1000.

  With 10g and later he get a 100 lines, which store in a buffer internal and then make the loop once 100. With a 1000 lines to fetch, it requires 10 extractions in bulk instead of one 1000 rank of extractions.

  These extractions require a change of context - as the engine PL must not out back, and in the SQL engine to extract a line. It is an overhead projector and can become so slow the context switch nothing more.

  And it's the construction of bases for this loop (and most other cursor loops) in PL/SQL.

  The ideal is to reduce the number of context switches. It is an overload that can have an impact on performance.

  What about using a loop in a loop. As 'bad '. This example uses the outer loop to retrieve the data. These data are then used to excite the extraction in internal or nested loop. The outside loop draws data from the SQL engine in PL variables Inside loop drives that same data back to the SQL engine.

  Why? It would have been much faster not to pull and push data between the loops using PL.

  It will be much faster do so only through SQL. Write the two loops as a single SQL statement and have the SQL engine directly driving these loops itself. This is called a JOIN in SQL. And the SQL engine can do not only more quickly, but it has a few algorithms of multiplied can be used which are even faster than a nested loop process (called merge joins, hash joins, etc.).

  Bottom line. Optimize SQL. Reduce to a minimum the PL. *

  Do as much of your data, crunch in SQL as possible. SQL is the fastest 'place' and process the data. No PL (or C/Pascal/Java).

  Hello

  As you discovered, you cannot use SELECT DISTINCT and sequence. NEXTVAL in the same query.

  You can SELECT DISTINCT in a subquery, like this:

  CREATE TABLE     student
  AS
  WITH     distinct_ids     AS
  (
       SELECT DISTINCT     student_id     AS id
       FROM     students_table
  )
  SELECT     st_seq.NEXTVAL     AS st_id
  ,     id
  FROM     distinct_ids;

• How to use Boolean loop values from 2 different sources to stop awhile?

  I'm working on a program for homework indicating E5.4) using a single eLoop Whil, build a VI that runs a loop N times or until the user presses a button. Be sure to include the time delay Exress Vi so that the user has time to press the stop botton.

  I am doing this right now, but it seems I can connect only one thing at the stop sign onto th while loop. It won't let me connect a comparison between iterations and N as well as the stop button at the stop sign onto all loop. So, how would I be able to structure so that it stops if it receives a true Boolean value of one of the 2 sources (both whichever)?

  Basically, I can't thread the result of the comparison of N and iterations as well as the stop button the stop on the loop about button to put an end. is there a solution?

  I'm stumped on how to make an offline recording when you save data in an Excel file. I don't want to save this in the loop of consumption will appear that the cover is locked. I read here that the best practice is to make a second loop to manage backup routines, but I don't know how to implement this. Can I use a different queue to do this, or is there another method?

  The loop of consumption may also be a producer for a second loop of consumer.  Simply use a second queue to pass data from the first loop of the consumer in the second.
