Dynamic call VI without FP bug leak

• Re-use of dynamically called code of target in real-time on PC

  I have a code that is deployed on a target in real time what I call dynamically. I also want to use the same code dynamically on a PC in the same project.

  This works very well when you run interpreted code in form. However, I can't add the dynamic called VI to build on my PC specification if the VI is under the aim of RT in the project. I can only include it in the build specification that is in conjunction with the software to the target of the RT.

  How can I use this VI dynamically in the ad for the construction specifications and places without having two copies of it?

  I actually found a way using a static reference of vi:

  

  Rather than providing a path to the file of the 'open' vi reference, simply load the VI statically and I then enter its name to open an instance, re-entering. This approach has the advantage of process Dynamics called VI as if it was dropped on the block diagram - I don't have to explicitly include the vi file in the build specification.

• Dynamically call a demon or an actor VI in TestStand

  Hi all

  The context:

  • I have a non-reentrant VI that must run in parallel to a sequence
  • This VI is opened and closed several times during the tests.
  • I close the VI sending him a pending request as it closes.

  It seems to me that there are two ways to start the VI:

  • Have TestStand call a LabVIEW VI that launches the dynamic VI. This could be the static node in the CGRA or an invoke node using a ref VI.
  • Use the asynchronous step "Run VI" in TestStand type.

  Right now I use the step "Run VI" asynchronous. I do not use the option "Reserve loaded live for execution", and once from time to time I get the crash 'TestStand sequence editor has stopped working ".

  My questions:

  1. With regard to memory management, which is the best way to put in place my use case? Is it better to have LabVIEW make the dynamic call or TestStand call dynamic?
  2. What is the difference in between both of these memory management works?

  Thanks a lot - suggestions are appreciated.

  Mr. Jim

  Let us know how it goes with the movement of the sous-suite.

  Basically the call run VI Asynch just dynamically create a sous-suite and qualifying in a new thread.  You can view it in the definition of step Type in one of the PreSteps.  But using the subsequence you eliminate the part of the dynamic generation of it (I've seen topics with, similar to what you describe).

  Good luck

• With the help of dynamically called screw in TestStand deployment

  I write code to interface with a & Rohde Schwarz ZNB Network Analyzer.  I use LabVIEW 8.2 and TestStand 3.5.  For reference the ZNB driver is available here: R & S of ZNB Driver.  I use a slightly older version of the driver, some before they needed to LabVIEW 2009.  I am writing all the code on a development machine that has the full version of TestStand/LabVIEW and it works on another machine that has the TestStand deployment license.

  This driver is dynamically linked to some things he needs.  I am able to operate with simple LabVIEW EXEs but not in TestStand deployments.  The following excerpt comes from their documentation, explaining a little about how the driver works and how to use in LabVIEW EXEs.

  3.4.2 How to generate executables or libraries in LabVIEW driver kernel drivers instrument based on attributes is dynamically bound to any VI performed during execution. This can be recognized by the LabVIEW application builder. The LabVIEW application builder follows all the static dependencies and include them in the package distributed at the generation of an executable file.

  To create an executable in LabVIEW, please manually add all the screws in the \PREFIX \_utility\callbacks folder to the LabVIEW project. In the case of project based please add private to your project folder. With this reference manual, the driver core is included in the compilation and the driver core is accessible during execution.

  I can't get this to work in TestStand deployments at all.  I can't even connect to the device since the VI Init has these issues.  I get the same error for all the various attempts that I made.  The same error is that when you add manually the screws for the LabVIEW EXE.

  So far, I tried the following, all solutions producing this same error.  I struggled with this and turned off for awhile then maybe there are other solutions attempts I forget.

  (1) it looked like a lot of the report to go to the private folder were finished in SupportVIs.  I manually pasted the rest there, too.

  (2) I added all driver files on my workspace and included in the files with the rest of my deployed screws.

  (3) I added all driver files on my workspace and said pilot TestStand to deploy them to the original location in Program Files.

  Someone at - it ideas?  R & S didn't even know what was TestStand, so that they could not help me.

  I was finally able to solve this problem on mine, the other day.  I brought the Network Analyzer to my office and did a lot of tests in this way.  Eventually, I discovered that I needed to include the folder private pilot deployment, what I was doing in one of previous attempts.  It turns out that you must also maintain the original of this file directory structure when you include it, otherwise dynamic calls are not looking in the right place.  Once it worked on my PC, I got it on the machine test and worked as well.

• dynamically called vi, PDM invalid file reference

  Hello

  I can't explain a strange behavior, I hope someone can give me a hint.

  First of all, do not ask why I need this way to go, I would like to understand why this is happening.

  We have a FGV which has 3 actions: Init, write data and close. It works on the TDMS files. The action of the init creates a TDMS file reference that is stored in a shift register to be prepared, used by writing and finally narrow cases.

  Everything is OK, if I use this FGV simply in a main VI directly from the block diagram. So that I can init, write data and finally close the PDM file.

  However, for some reason, appeared a new requirement: to be able to 'Init' and 'Close' the TDMS file using the FGV, but within a dynamically called VI (a pop-up window that may not stop the execution of the appellant).

  So in primary VI, I call dynamically VI one another by using the asynchronous call (flag x 80, "call and forget" method), and it dynamically called VI fires the FGV TDMS.

  When I probe the reference of TDMS files, I can see that it gets its value correctly after the case 'Init' of fire. After this 'init' which happened (from Dynamics called VI), a location in the MAIN VI starts calling this FGV with enum action 'Write '. I can see via sensors, the case of writing Gets the same number of REF TDMS file which has been stored in the shift register after the case 'Init '.

  But even so, the VERY first function TDMS write throws an error msg "TDMS file invalid reference '! How is it possible, if the file reference is OK and the same as that created by the function 'File open TDMS' in case 'init '?

  Again, if I execute 'init' action also directly the main VI, not a third dynamically called VI, everything is OK, it works.

  I hope that my explanation is not too bad

  Thanks for the tips and if no idea, I'll try to recreate/replicate this behavior in a test project that is small, and I'll post it...

  The problem is that when the dynamic called vi stops all references that he open invalid.

  To see what I want to say, change the dynamics vi delay like 30 seconds before she stops, the savings loop works fine until the dynamics vi stops, then the error returns.

  Mike...

• Switch on the dynamic call

  I use packet sniffer example in my code with a few changes to calculate the delay of my data.

  I need to make a dynamic call to run this VI at some point my main code and stop at another point.

  Just to test I put some delays between market, stop and get the time as below:

  

  But in VI that I call, the stop button is inside a structure of event... like here:

  

  So... even if I try to stop the VI in my dynamic appeal, it seems that my VI will not read this change... only read if I manually stop the VI.

  so I try to stop at the first VI but does not stop... what could be a solution for this?

  Thank you

  Thai

  Problem solved. I just inserted the stop button in the same case where is Timeout, now I can guarantee you that this value will be read.

• Dynamically call DBMS_XMLINDEX to delete the setting and exit with the exception

  Hi all
  
  I am trying to create a procedure to dynamically call DBMS_XMLINDEX.dropparameter.
  If the parameter doesn't exist no then gracefully exit with the exception as "the parameter does not exist.
  But I keep getting errors because of the dynamic passing.
  Procedure is something like:
  
  
  Create PROCEDURE drop_parameter (p_parameter IN VARCHAR2)
  IS
  no_parameter EXCEPTION;
  PRAGMA EXCEPTION_INIT(no_parameter,-12004);
  BEGIN
  RUN IMMEDIATELY ' DBMS_XMLINDEX.dropparameter ("| p_parameter |") ';
  dbms_output.put_line ('abandoned parameter');
  EXCEPTION
  WHEN no_parameter THEN
  dbms_output.put_line ('parameter does not exist');
  END drop_parameter;
  
  For the implementation we can try to create the parameter in the form:
  
  BEGIN
  DBMS_XMLINDEX. () REGISTERPARAMETER
  'Param1 ',.
  ' PATH TABLE PathTB1
  Paths (INCLUDE (/ a/b / c))
  / d/e/f
  ))
  ');
  END;
  /
  
  The setting above should be deleted or if not existing, then exit gracefully.
  Please suggest.

• [CS6] [InDesign SDK] Any way to export SWF without a memory leak?

  He fled on the very last line. In other words, if I remove the ProcessCommand() then there is no memory leak.

  There seems to be 'leaks 2, 130072 bytes' leaks every time I call the above.

  I'm just stick the code that ships with SDK CS6 examples, so I don't see what the problem is.

  I checked the code

  Any suggestions?

  It could also be a bug in InDesign. You can check if you have a newer version of the ID? 8.0.2.413

• passage of queue to dynamically called VI

  In my application, I have two screws. IIn a VI I create a queue and then I spend the Ref. of the queue for the other VI and launch this VI dynamically.

  While running any VI can stop regardless of the status of the other VI.

  but as soon as I stop the VI who created the queue. the Ref. of the queue becomes invalid. and dynamic VI cannot use the queue more

  I want to the queue to be eliminated that after I explicitly call has queue function.

  How can I achieve that

  Hey Tushar,

  You can create a "functional Global ' which encapsulates the function Create tail and buffer the reference to the queue in a registry to offset.  The VI may have two modes of operation: CreateQueue and ReadReference.  The top-level VI he would run in Design Mode, and the VI dynamically saying would just continue to use the playback mode.  Since this VI remains a VI performance left even after the parent process ends, the queue reference, allocations will remain valid.

  See you soon!

• Unanticipated delays, the closure of dynamically called VI

  LV10.0 / WXP

  A VI is called dynamically by Method VI Run (wait until done = FALSE, Auto have Ref = TRUE).

  Queues are used to Exchange data with the main VI.

  Closing (the main VI "stop" message), the LabVIEW VI hangs for about 25 seconds (!) with one of the processors of the machine dual-core at 100%.

  Someone else met this strange behavior? Any ideas?

  Thanks in advance

  
  

• Block annoying calls. Without any application of part 3

  Is there a way to block calls on Xperia Z3. I get unwelcome calls in an area of 805. I don't want to download an application of part 3 due to the publicity. And barely work. Amy ideas?

  Hi Barcelona503,

  Unfortunately there is no built-in function, this kind of functionality is usually network based. However, you can arrange for phone number to go to voicemail, everytime without phone ever ringing.

  Menu > contact > choose Contact > press pencil icon > press 3 circles on the top right > press all calls to your voicemail.

  I hope this helps.

• can we use service legend to dynamically call business service in OSB

  My requirement is: contact service issue. moments of for - each loop in OSB. Node road that we cannot use in the foreach loop.

  can we use service legend to call business several times? and how can we pass endpoint url to business service using the legend of service.

  Please help me.

  Yes you can use routing options to override the legend service endpoint url. See

  http://docs.Oracle.com/CD/E23943_01/admin.1111/e15867/proxy_actions.htm#i1315299

  The action of routing Options can be used when the context variable $outbound is valid. It can be added to the following actions:

  • Publish
  • Dynamic publishing
  • Publish the Table
  • Legend of service
  • Routing
  • Dynamic routing
  • Routing table

• Dynamically add UIComponent without refreshing entire page (JDEV 11.1.1.3)

  Hi all
  I have this problem.
  
  I need to dynamically add an element within a page without refreshing entire page jspx.
  
  For example, look at this page:
  
  
  Titus: _
  Name: _______
  Job: _ (+ add more jobs)
  
  When I click on (+ add more jobs), I add a new RichInputText:
  
  private RichPanelBox pb1;
  
  public String cb1_action2() {}
  RichInputText rc = new RichInputText();
  rc.setId (...);
  [....]
  This.PB1.GetChildren (). Add (RC);
  Returns a null value.
  }
  
  The field is displayed properly on the page, but the system do a full refresh and lose your position on the page.
  
  Obviously becomes inconvenient for the user to have to scroll the page up to a certain point where it was before.
  Is it possible to avoid this problem and to add the field without a complete refresh of the page?
  
  Thank you
  Cristian

  Try with PartialSubmit for the button and use PPR as follows:

  JSPX Code:

  
  
  
  
  partialSubmit = 'true '.
  actionListener = "#{SamplePageBean.onAddJobs}" / >

• dynamically call an XML

  I have various xmls loaded into a table. I need to pass one of the xmls using a class based on which button is clicked. I can't find out how to do it dynamically.

  Here is the chart:

  This is the class which need the XML passed through:

  var custClass:CustClass = new CustClass(); How can I putl the xml code in the brackets without Hardcoding it?

  How do you propose that I could go about this?

  :

  xmlArray:Array = [xml54, xml49, xml53, xml52, xml43];

  var custClass:CustClass = new CustClass (xmlArray [variable1]); / / where variable1 is defined in your earpiece button function
