• Cancellation of registration user stored in the shift register event generates the error 1 if Subvi runs intermittently

  Hello

  I'm trying to understand the behavior of the attached excerpt from a larger overall vi functional.

  In a State, I'm generating a user event and in a State later unsubscribe from the event and destroy it.

  Now, if I went through the VI together in one step (i.e., step through events? set to FALSE), the VI runs without generating an error. However, if I run the VI by intermittent and output after each execution of the loop, the vi generates error 1. Why is it so? Please notify. Thank you.

  Why are you registration and deregistration of events user, but you have no event structure in your VI who use them?

  When you run events, probaby the event you registered disappears when your VI stops running.  If you were able to keep your VI in the foreground running, then the life of the event would persist.

  The event number still exists in the uninitialized shift register, but it does not say more once your high level VI stops and you get the error 1.

  If it was really a global functional VI, you would terminals connected to the connector table in your VI, you would call this as a Subvi as part of a main VI and life event would persist and you wouldn't mistake 1.

• Prompt the user for a parallel process

  Hello

  I am developing a software where I constantly read data from equipment. There is a command that requires a password to enter in this software. I tried to use the query the user entry to receive the password for the user. However when the guest user screen opens, my software stops the reading of data from the equipment until the user enters the password. I don't want that. I want to read the data coming from the equipment, while the user inserts the password again.

  Is it possible to run the query the user entered a parallel process during execution of the read data part? Is there another way to request a password from the user?

  Thank you for helping!

  Hi Ariyoshi,

  LabVIEW is based on DATA streams. When there is no dependence on the data between segments of code, and then they run in parallel.

  Put your password dialog box in a parallel loop...

• VI, Structure of the event - script user events

  Hello

  I'm writing a VI script, which will focus on a structure of the event in another VI and fill the event with registered user events connected to the dynamic Terminal structure.

  I use the 'SetHandledEvents' invoke the node and the wiring to the terminal of dynamic events.

  In my example VI, I created 3 num event user, Boolean, and string. I can right click and add the event very well to the structure of the event. Now, if I remove any of the event and run my script I can add a dynamic user events. If I change the number of gegistration event from 1 to 2. I get error 1. The case of the event is created, but it is not configured for any event.

  Any help would be greatly appreciated.

  

  My test images vi showing events three user sign-up.

  Attached is the VI containing my script.

  Thanks in advance

  The user 1 problem script error event should be fixed in LabVIEW 2016. DQMH did a lot of event scripts, but it cannot automatically configure event framework names... the user must do this manually for now.

• My wmi file is missing. I am running windows xp home with sp3 addition

  whenever I try to use the windows diagnostic utility or if I try to use any microsoft diagnostic tool always happens the same thing. Sometimes it does not find my wmi or its lack. What can I do to fix this?

  Looks like the Windows Management Instrumentation Service is not running or your information from WMI files are missing or damaged. It is easy to rebuild the WMI information files and replace all the files corrupted or suspicious.

  To solve your problem, stop the Windows Management Instrumentation service, rename the folder suspicious or with WMI, restart it your system.  When the system restarts, the WMI service will automatically start and rebuild the WMI folderand is automatically the content.

  Click Start, run and enter in the box:

  services.msc

  Click OK to launch the Services applet.

  Locate the Windows Management Instrumentation Service.  If the status column indicates that the WMI Service is started (ongoing), right-click on the WMI Service and choose to stop the WMI Service.

  Answered in the affirmative, if requested to stop Security Center and Windows Firewall Services (with stopped services, your system is vulnerable to attacks from the Internet, so do not receive is not on the Internet again until you reboot your system).

  Now would be a good time to check also the properties of the WMI Service to make sure the startup type is set to automatic for the Service WMI will start automatically the next time the system is restarted.

  The Explorer, navigate to the following folder (assuming that your boot drive is C):

  C:\Windows\System32\Wbem\
     
  Locate and then rename the folder "Repository" to something, as you remember, such as:

  Repository.Old

  Restart the computer, and then make sure that the WMI service is restarted automatically and that a new repository folder has been created to replace the one that has been renamed.  It may take a while to completely rebuild the file storage (several seconds or minutes) so expect it ends.
     
  After the reboot, you will notice the wmiprvse.exe Service running in the Manager of tasks and he will continue to run until it completes the reconstruction of the repository.  This may take several minutes depending on your system, but eventually the wmiprvse.exe Service ends and disappear Manager tasks.

  If you then look at the Event Viewer Application log, there may be some error messages like this:

  Event type: error
  Event source: WinMgmt
  Event category: no
  Event ID: 4
  Description:
  Failed to load C:\WINDOWS\MICROSOFT.NET\FRAMEWORK\V4.0.30319\MOF\SERVICEMODEL MOF. MOF by retrieving the file from the repository.

  This is normal because when the system restarts, the wmiprvse.exe process has to rebuild parts of the repository as well. It is a mistake to sequence as shown below. You should not see these mistakes again after the system has been rebooted and catches up and finishes rebuilding the WMI repository.

  Explanations for errors encountered in the case of the Application of visualization of the newspaper the WMI repository is rebuilt:

  Explanation
  Windows Management Instrumentation could have tried to compile the file (mofcomp) a .mof marked for ASR, but compilation failed.
  This is probably due to a sequencing problem.
      
  User action
  To correct the problem, try to compile the .mof again. If this does not resolve the problem, contact the vendor of technical support for the program
  in question.

  You shouldn't need to do something about these error messages and do not see again them after that XP has finished rebuilding the WMI repository.

• Events of waiting "log file parallel write" / "log file sync", in CREATE INDEX

  Hello guys,.
  my current project I'm running a few tests of performance for oracle data guard. The question is "How LGWR SYNC transfer influence the performance of the system?"
  For the performance of the values, that I can compare I just built a normal oracle database in the first step.
  
  Now I perform various tests such as creating index 'broad', massive parallel inserts/validations, etc to get the marks.
  
  My database is an oracle 10.2.0.4 with multiplexed on AIX log files.
  
  I create an index on a table of "normal"... I have run "dbms_workload_repository.create_snapshot ()" before and after the CREATE INDEX for an equivalent period for the AWR report.
  Once the index is built (round about 9 GB), I made an awrrpt.sql for the AWR report.
  
  And now take a look at these values of the AWR

                                                                     Avg
                                               %Time  Total Wait    wait     Waits
  Event                                 Waits  -outs    Time (s)    (ms)      /txn
  ---------------------------- -------------- ------ ----------- ------- ---------
  ......
  ......
  log file parallel write              10,019     .0         132      13      33.5
  log file sync                           293     .7           4      15       1.0
  ......
  ......

  How can it be possible?
  
  With regard to the documentation
  
  -> synchronization of log file: http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/waitevents003.htm#sthref3120

  Wait Time: The wait time includes the writing of the log buffer and the post.

  -> log file parallel write: http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/waitevents003.htm#sthref3104

  Wait Time: Time it takes for the I/Os to complete. Even though redo records are written in parallel, the parallel write is not complete until the last I/O is on disk.

  This was also my understanding... "log file sync" wait time should be higher than the 'parallel log writing' timeout, because of, it includes the e/s and the response time for the user's session.
  I could accept it, if the values are near each other (perhaps around 1 second about altogether)... but the difference between 132 and 4 seconds is too visible.
  
  Is the behavior of the log file sync/write different when you do a DOF as CREATE INDEX (maybe async... like you can influence it with COMMIT_WRITE initialization parameter?)?
  You have no idea how these values born?
  
  
  Ideas/thoughts are welcome.
  
  Thanks and greetings
  

• trigger several events to user in an architecture of producer/consumer

  Hi all

  I use a producer/consumer architecture, where the case within the property are selected with enums sent via a queue.

  Enums are queued in the producer, which is a Structure of the event inside a While loop. Then each of the events in the producer is associated with a case in the well (to make it easier).

  Now I would like to run several events in the producer, programmatically in a given sequence. The events involved in the sequence are basically all triggered by changing the value of a Boolean value (button).

  Please find attached a schematic representation of the sequence, I would like to implement.

  I heard of 2 solutions:

  -"Writing to the node (Sgnl) Value property of the variable [I] want change."

  -Dynamic user events

  In any case, I don't know how to make sure this is done for several events in a specific sequence?

  Thank you.

• Access to the new data in Event Message user callback?

  I use the Simple OI LabVIEW as a template for my user interface for TestStand.

  The sequence sends a Message to the user to the IO to the string array of tests to run.

  But I'm having a lot of difficulties this string data in table for the VI event reminder.

  I don't want to use a global variable and so my method without success so far has been as follows:

  1. use a Refnum at the matrix and pass in the event reminders VI through the cluster Config

  

  2. the "selected Tests" in the entry in the Config cluster event reminders VI is a generic control Refnum

  

  3. the selected Tests (below) is then delivered and passed in the User parameter

  

  4 but how to convert the refnum control Tests that are selected in the original array of strings in the real callback?

  ???????

  Also if there is someone who can suggest a better way to do this then please let me know.

  The line at the bottom is - how to get the most recent data in the event callback function when it is called?

  Thank you very much

  Ronnie

  Ultimately to get this working, I gave up on the string table and changed to a ListBox instead. It was easy then to access the properties of the listbox through the refnum. Probably a major flaw in my understanding of how string refnum work tables.

• Problems with the opening of attachments when the user has restristed privilege to run executable code from Program Files and Windows folders.

  I'm trying to prevent users from running potentially dangerous files. According to the Windows policies so I put. Users can run any application Program Files, files (x 86), windows, and folder to all users of the program office. Users have no permission to write anything in this files. When the user double clicks for example document.doc on his desk - document opens fine with MS Word. But when the user tries to open this document in attachment directly (by selecting open with MS Word, instead of the economy) - he sees an error - "this action is limited by local politics. Ask your system administrator. "(not exact text).

   So I want, users able to open attachments from Thunderbird automatically, but not able to run any application or link, except Program Files, Program Files (x86), Windows and all users' desktop folder. How can I get this result?
  

  Thanks in advance.
  Calvo is serious.

  PS Sorry for my bad English. It is not my mother tongue.

  Thanks for responding.
  I discovered what was going on.
  This strange "bug" affects multiple computers with Windows 7 Ultimate in my case.
  When you create a SRP (software restriction policies) it creates two rules by default to run programs: windows folder and the Program Files folder. I manually add "C:\Program Files (x 86)" in places without restriction. BUT Windows and Program Files folder to default rules directly, but through registry keys. And this part seems difficult. You CAN run the executable files of Program Files. You CAN run the Program Files (x 86) executables. But if Thunderbird or Firefox try to run MS Word or excel or editor for.doc or *.odt opening or another file - downloaded files running programs blocked by SRP.
  In order to fix this, simply replace the rules for indirect paths like % HKLM/software/microsoft/windows... etc % with direct, for example "C:/Windows" and "C:/Program Files /". After that, everything works fine. Attachments and downloaded files automatically opens without a problem.

• For parallel loops run on hearts of dedicated processors?

  I don't think that this is the case; My confusion is due to the fact that the literature regarding this structure addresses using the maximum number of cores the computer in which this codemay run in the dialog box for parallelism but also loop iteration using the CPU Information function to determine the number of instances to parallelize. I suspect that parallel loops For will first of all be decomposed into Tufts/tasks of iteration which will be either in versatile collaboration & and/or multithreaded in a system of priority of execution before they ever get to be mapped to hearts dedicated instance. Is this correct? -literature, I want to talk about is Improving Performance with loops parallel http://zone.ni.com/devzone/cda/tut/p/id/9393, under the guidance of Performance or the help of LabVIEW (multiprocessing and Hyperthreading in LabVIEW). I don't see how this information applies to how the loop bodies parallelized and executed. I hope someone can enlighten me and perhaps others to read these documents.

  Thank you!

  jorgeinSD, thanks for the insightful question. Your second option is correct. Each instance of a parallel loop is in a different bouquet and schedules of delivery system of these Tufts between the available threads. LabVIEW does not bind son to cores for the parallel loop, so threads can switch between the nuclei they run.

• Structure of the event within the structure of the case run once

  Hi all

  I am a controller using myRIO and labview where the program compares a value of the probe in a "Preset" and then choose a structure case depending on what type of air supply is required. What can be seen on the picture, for example, is 0 if saturated air supply is necessary.

  The structure of the event is used to send a signal to step to the stepper motors to open the valves (closing is still pretty much in the same way). In any case, the event turns my valves 90 degrees. I read the sensor all a second, however, when the case remains unchanged, the case runs the event again causing my engines running at 90 degrees per second (essentially continuously). What I'm looking for is a way to send the signal to step only once until a new case is selected.

  He is not on the photo, but this is all within the large loop.

  Apologies for any bad/cringeworthy coding, it is literally my first program always using labview. I can post the full VI if you need.

  Any ideas would be very appreciated! Thank you

• event without user data

  I'm just starting using custom user events.  It seems simple to create one, but it seems that the purpose of block diagram "Create User Event" rather presumptiously assume that I must have some data related to the event.  Sometimes we do, of course, but other times, he simply need to know that the event took place.

  I think it is stupid enough to create me a bunch of kinds of dummy data for events that don't require data.  Is there a way to do this?

  Thank you.

  You never know when you might want to spend data, or perhaps spend more data than you already are.  So in my creations I usually have a variant empty as the default data, but have this variant be a def type.  In this way in the future if I have a few settings I want I can update the type definition (it is a Variant) with the actual data, I'm worried.  Or even to pass data in the variant as a variant attributes.  Maybe I want to say my exit command to have a timeout on kill some other tasks, or maybe I mean my exit make a taskkill, or who knows.  And if this variant attributes aren't there then just exit as usual.  My point is in the future can I want to send some data types as well as the command to do things.

  There were times in the past when I throught "I will never need to send any additional data.  Like once I sent an order to a caller VI to close a floating window and insert it into a secondary.  Then I realized that I might want to send a command to shoot VI on the secondary and make it float so I added a Boolean value.  True means that shoot out, False means put in.  Then I realized if I want to order the window position and size of a walk.  Finally I did it in a type definition, but in this case I should have done this from the beginning.
