Front Panel does not (exactly 2 even while in flat sequence loop)? LabVIEW BUG?

Hello world

I have two while loop with exactly the same code and a user in each loop event structure,

They both make the same thing which is too run until IMAQ image control (one line) click on a recording.

I used a flat sequence to manage the order of execution.

The problem is when I use only one single loop (put another in a diagram to disable) the façade answer perfectly and the program does what it should, but when I activate the two loops stuck in case of timeout...

I do not understand what is happening that I can't do any activity of façade that would be registered, enclosed is a copy of the VI (you need NIVision run the vi).

Any idea? Is this a bug or did I do something wrong?

Thank you very much

Best regards

This isn't a bug, but the expected behavior. You cannot sequence structures event like this, they both need to be ready to react. Use a single event structure and a state machine architecture. You have about 4 copies of basically the same code of event management. Try to combine everything in one!

What happens in your case?

Answer: The two structures event will begin immediately queues of events, but the second event structure cannot respond to them because it is inaccessible due to data flow. In addition, the second structure of the event is set to "lock the front panel until the end of the event. Given that the event cannot end as explained above, the façade is locked up forever.

  • Controls on the front panel does not work

    In the attached vi (I've stripped down to simplify things), I have a problem with the controls on the front panel does not when you click on the control to acquire it. It of probably something obvious but got me to loss.

    Thank you

    It is probably because you are in the State to acquire until you're done absorbing.  Meanwhile, none of your other events can run.  You have events to acquire: let the mouse.  There is a setting for "Panel before locking up the end of the occurrence of the event.  Given that the event cannot process until your State acquisition is completed, the façade will be locked.

    I would recommend another loop for the acquisition of your data.

  • Front Panel does not work on my Qosmio x 305-701

    I m using vista 64 bit and my started Panel does not.

    Like the other problems with this model, I hear the beep when I touch the buttons FN keys work fine.

    My bios version is 1.70, the last one being for the moment.

    Toshiba Hardware Setup Utility, TOSHIBA Flash Cards Support utility is installed and running, but when I try to install the latest version of Toshiba value added for Windows Vista I get ID_ERR_NOTINSTALLVALZ_MESSAGE and not able to continue the installation.

    Is there anyone else does in the face of this problem so far?

  • Front Panel does not properly

    Hello

    I have problems with some parts of my VI that I can't understand. The most important is that the elapsed time VI and Stop button not work properly on the front panel. Currently, the elapsed time don't go from 0, even if I want to count all the time, that the program is running and stop when the target time is reached. This is not the case. In addition, the stop button in the while loop does not stop at the VI to run. Why is this?

    Any help is appreciated!

    Well, if you get all the data to the serial port, you currently have a 10 second timeout.  So I think that your buttons are working, you just are not waiting long enough to see them act.

  • VI front panel does not close when it is done executing, when this vi was called by reference.

    I created a simple vi set to indicate the problem I'm having. I run dynamically under vi to leave a main application. Simply the main application is my test exec and the Subvi I call dynamically is different tests. In the example I have write here the criterion vi is called Test electric 1(vi). I configured this electric Test 1 vi to see the front when it is called and close later while initially closed.  Problem is that it doesn't close before.

    Other things to keep in mind

    • I want to be able to run the vi test and do not wait until it is done.

    I'm using LabVIEW 2012 SP1.

    Basically the fence after that call questions only if the VI is called as a Subvi (as if you open you a VI and run it, it does not close when it's done).  Are two ways to work around this or have your app high lvl close the VI when it's done, it's explained here:

    http://digital.NI.com/public.nsf/allkb/987B2026B41BD39786256CF800032E8C

    or having your VI close when it's done.  A reference of the VI and the front panel: Close call node.

    I hope this helps.

  • Security on the front panel does not work

    Hello

    I have a problem and a question:

    Problem: I created some controls on the front panel and some groups which they are responsible. Administrators can see and do everything, the operator cannot see some of them. If I build exe it works on development PC but if I copy them to another PC, it does not. It does not show these elements of façade. Areas are the same, SCADA, only the names of PC are different. The two computers are not in the same network. I create local domains and users on two computers through domain account manager. What could be the problem?

    Question: How can I create an access control list (ACL) and assign them to the elements of façade programmaticaly? What is the syntax? I have found no examples of code.

    Thank you.

    I found the solution. Maybe someone also needs:

    You must copy the folder C:\Program Files (x 86) \National Instruments\Shared\Domain development pc to other PC, in which you want to have the same field and same users. It does not have to generate the new domain with exactly the same name on another pc and generate new users. You must copy the whole directory of your pc to the other pc. It works now.

  • Satellite A200-1N1: "Satellite" LED on the front panel does not light up

    Hi people!

    I noticed that my LED with the word "Satellite" on the front panel lights.

    You have all the hypotheses on the causes?

    Hi Maresha,

    The front 'logo' LED is enabled or disabled using a BIOS "Display front Logo" option that can be set on IT or OFF you need. Access your BIOS settings (F2 at startup) and check that this setting is set to 'ON '.

  • Japanese police on the front panel does not

    Hello

    I'm new on the use of LV and learns that when I hit a Japanese character, it indicates text of garbage.

    System:

    Windows 7 Pro 32 bit SP1

    LabVIEW 2013

    Problem:

    Whenever I touch in Japanese characters, the result is garbage, but when I tried to export the VI, and when I open the txt file, the character is written correctly.

    Looks like that in the front the characters are displayed incorrectly.

    I have attached the locale and also the garbage in the façade for reference, as well as the printscreen of the txt export.

    Any solution for this one?

    Ahh... It solved!  Region/language format must be set in both Japanese... (Local and location should be also at the Japan) weird...

    For users speaking Japanese, it may be difficult for you because the clock/date etc will also be in Japanese.

    In any case thanks for the responses I got from you guys... Bravo will be given
