Freezing of front panel

When I run my VI it will sail between the tabs and the front panel will not freeze if I do not enter the voucher code and simply press the home button.  However, when I enter the voucher code (1234), then the program brings back me to the Home tab but then freezes the front panel.  I tried running without highlighting the execution until I have enter the code and quickly press the bulb to see run step by step and when I do that it goes back to the home screen and that it does not freeze so I paint a white on why it freezes.  Any help would be greatly appreciated!

I am new to Labview, so I don't know that my code is poor.

Your code is backwards.  Why is the case your outermost structure structure?  In which case runs is determined by which tab is selected when you press the run button.  The while loop must be the outermost structure.

  • NEED HELP FAST - façade freezes when I run my program. I have all the events to the interaction of the façade. I don't have a chance to launch an event that I can't even click on anything whatsoever on the front panel?

    All,

    I'm pragmatic disabling most of the façade with a particular event. This freeze happened when I launched this event and then stopped the program in the middle of the event. While the program has been frozen at all times no matter how many times I turned on my computer and turned off and restarted labview. I tried with pragmatism, allowing some of these objects on the front façade of the loop of events without result. What else could it be? When I select the program stops at the structure of the event and is waiting for him. When I have a finite number of thread for the time terminal timeout the timeout event runs and then waits for the structure of the event and I'm still not allowed to do anything.

    Yenkip,

    OK, the moral of the story when programmatically disabling an object to front panel make sure you have the code that allows very early in the program, changing constantly in the middle of the program changes its active status. I tried enabling some of these objects, but not all. When I tried allowing each of them, I realized that everything in the deactivation of the tab control tab control disables not only the ability to change the tab control. IT WASN'T THE STRUCTURE OF THE EVENT. The guys help OR on the phone told me that the structure of the event was obviously the question. I'm fine now.

    Thank you

  • HP EliteDesk 800 G2 Small Form: The front panel audio connector - this only made type to use for headphones and microphone

    Hello

    I am trying to determine what type of audio 3.5 mm plug to put into the connector on the front panel for the use of a headset to make video communications.

    could be - sleeve, ring and end cap (mono audio and microphone)

    or

    could be - sleeve, ring, ring and tip (stereo sound and microphone)

    Having read through the manuals and nothing is said on the type to use.

    Hello world

    Just plugged the connector 4 poles on my headset combination for my mobile phone (cellular) and the box of pop - up asked me to select headset or microphone - no selection for both.

    Looks like the right sleeve is for headphones only, and the left one is for headphones or micro - selectable by the user and not the two on a single sheet.

    Everything explained by the practice - but not the paperwork in the manuals.

    #5 for microphone or headset - menu popup is displayed after you insert a 3.5 mm plug to select that one but not both at the same time.  (So I can't use my headset to phone)

    Thank you

  • WANT 411c: MFP ENVY 411c lights on the front panel

    I find anywhere a note detailing the two LEDs on the front panel of the printer.  Of course, the left is the power light and the Start button / stop.  The other, 1/2 "to the right, has an icon as the icon of WiFi or wireless, or whatever it may be as an antenna with a radiating signal left and right of it.  What is this for?  It seems that there is a hole below and to the right of the symbol, but nothing ever shows up.  I turned off the wireless and turn it back on and or State shows a light here.  I reinstalled the software checks to see if that mattered and it made no difference.  I also unplugged the router and the printer, and that has not changed anything. It is connected to my wireless network and works very well.  What this has to do with some additional services such as ePrint?  I just lost some of them September 1, 2016.  Perhaps the only light when something just one of them?

    Hello

    That your work as expected wireless connection, there no problem with the wireless printer, just with his lamp wireless card.

    The lamp to indicate the wireless connection is turned on and must turn on once connected wireless.

    They have nothing to do with ePrint or any Web service, it must turn on once connected to a local wireless network.

    As you mentioned that you are connected and the printer maintain a wireless connection, it's probably just a blown bulb.

  • Satellite L500D - what is that annoying red light on front panel?

    Hello

    I have my L500D the normal five system LEDs on the front panel of the base computer, where they are supposed to be. But then, to the left of these fires, there is that annoying red light, which is very distracting.

    But what is even more annoying than not one, + not a + manual owners I've read mentions none, + not even a hint. The manual mentions the other lights in their patterns, + but not this one. :-(

    Now, I'm assuming it's something really simple, and I publicly show how blind or stupid (or both) I really am. :-) But for love all holy, and before that I lose all of my hair, can someone tell me what is all simply as the red light?  :|

    And, while you're at it, maybe you can tell me how to turn it off! It would be a very unique experience for the moment. (B-)

    Don't get me wrong, I love my new L500D, my best investment by far and it goes like the wings and I write about a wacky ad jingle and broadcast around the world... If not for the boring red light. ;-)

    Help, please! (i)

    Hello

    I think you are talking about a wireless light located on the front left side of the computer. You can see here:

    http://laptops.Toshiba.com/laptops/satellite/L500

    Yes, it's a little boring, but you can turn it off by pressing Fn + F8 but in this case the wireless connection turns off. As for me, I use any wi - LAN, my knees is connected to the Internet by cable, and I never use outdoors.

  • e9180f: removal of the front panel? e9180f

    Hello, I need to clean my power swith (on the upper edge of the front panel) due to a spill of food products.  I have a side removed by removing a screw in the back and then dragging to the rear of the side panel. I don't remember if I already had the cabinet apart one more than this. The front panel can break, but I fear I will "break the BAD thing. I'm sure that WD - 40 or other cleaner used by switch electronic only should be OK. Thank you all for help.

  • 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 '.

  • The front panel ThinkCentre M81 connector pinout

    I have a ThinkCentre M81. I am currently trying to put the guts of it in another case, so that I can add some more to it. I checked all the guides I can find on Lenovo's Support site and they show only the location of the connector and how repalce the façade.

    I try to connect the connections for the front panel ATX standard for my motherboard M81, which I'm having trouble with, reason for the connector of the Panel before Lenovo comes to be a big connector.

    I wonder if this information is a resource that I missed somewhere, or if I have to trace the wires.

    It is not your model, but maybe they are similar:

  • OR scope Soft Front Panel fails to load

    Hello

    I use the scope Soft Front Panel OR with my USB NI 5132 for some time successfully. However, recently it has stopped working completely - seems to load a bit then fails before you even open the screen. The same thing happens in MAX I did all the updates critical, uninstalled then reinstalled NI Scope, uninstalled Labview (the only thing I had changed after the last time, I know that it worked successfully) and checked the nitaglv.dll library was in the right place according to this post: http://digital.ni.com/public.nsf/allkb/63739991438EC593862579C6007301EC

    So far nothing's worked. I NI SCOPE 4.0 and NI-VISA 5.3.0 installed, and the computer could see successfully the digitizer USB 5132 Max after the relocation OR scope, well that the flexible façade does not always load and making the Panel test Max also does not.

    I have attached a picture of the screen to load before it disappears so that could provide clues.

  • OR DC Soft Front Panel, minorbug, small bug with the PXI-4110

    The NI DC Soft Front Panel V14.0, with the PXI-4110, scrolling to negative tension, works as expected to-10V, but then returns to 0. If we change from - 1V procedure, it goes...-8-9,-10, -1, -2... instead of-8-9,-10, -11, -12...

    I completely agree with two of your statements, I tabled a report of corrective measures that you can monitor in the next versions of DCPower to see if this is fixed with the FPS. CAR number: 512257

  • OR SWITCH Soft Front Panel

    Hello

    I have a few questions in the following way:

    1. After installing the Switch Executive 3.6 (evaluation software), I have very large window for OR Soft Front Panel SWITCH to cover all 4 monitors. It is difficult to see. Do I have to uninstall 3.6 Executive switch (software evaluation)? We don't need that much. Is it safe to uninstall?

    Could you give me the solutuion to configure on the previous setting the Soft Front Panel, released only to a single monitor.

    2. what the Panel "pxi-2720" test should be at MAX? If I click on the test Panel, 'Switch Panel Soft' appears with the topology - '2720-independent? It looks like swich instead of test programmable resistance. Is - this Panel good criterion for pxi-2720?

    3. for NI PXI 2571, I SH200LFH-4xDB50F-C cable to connect to the terminals and tested the switches. I found the NO0 (P1 pin2) - COM0 (P1 pin1) connection is not working while others work. That is reserved by something else? I have test by exchanging terminal blocks, but the result was the same.

    I'm waiting for your answers.

  • Can I programmatically change the default property to create for all elements of the front panel?

    Can I programmatically change the default property to create for all elements of the front panel?

    I need to make the logout button, when click on, takes care of all the default values of my fron Panel.

    There is no way to programmatically call the functionality of an editor 'Use default' or 'Load Default'. To do it yourself, you will need to write your default values for each control explicitly in the diagram, when the user press the logout button.

  • Usability is NOR-SCOPE Soft Front Panel for the PXI-5154?

    I am plans to use the PXI-5154 with his NO-SCOPE Soft Front Panel in a product to test instrumentation. Our past experience, our users need an on-board scope that is easy to use which does not load the CPU. In most cases the scope will be used to check a transitional type of pulses. So, the amplitudes and rise times are essential to ensure compliance with ISO standards. The ability to capture, store and recall traces of reports is important, as well as the ability to perform simple and reproducible follow-up measures. We don't expect our users to have to program the scope; "give me the waveform.

    Does anyone have any comments on the usability of the NOR-SCOPE Soft Front Panel? How to compare with other soft scopes?

    Hello!

    The scope Soft Front Panel is very user friendly and able to load/save waveforms, Load/Save settings and make the scalar measures.  I've attached a screenshot of what the front soft worn looks as well as a link to a help document on the high speed digitizer HELP.  Information on the scope Soft Front Panel lies in this document and can be found under the tab content in the configuration tree (NI - Scope Soft Front Panel help).

  • Switch Soft Front Panel, active device classified

    I have a with PXI chassis modules, two switches PXI-2350.  Using the Soft Front Panel switch, it seems that the names assigned to the list of active device (both 2350's in this case) are backward, what to expect.  Is there a way to reassociate those names to the 2350's physics?

    Thank you

    Confustus,

    It's an interesting question that I've never seen before, your devices in a Soft Front Panel should be linked to features like labels in MAX. I was wondering, when you say "we can select using MAX, a road that connects the power supply to the digital multimeter using"Switch 1"(for example), and we can see the voltage reading show on the Soft Front Panel 4071 as planned", what you mean exactly? If you had to choose your hardware device, and then click test panels, the NI Soft Front Panel load switch. Are you saying that when you choose test panels and loading Switch Soft Front Panel of max works as expected, however the application outside opening MAX does not work?

    Or are you talking about the Test panels you open in NI Switch Executive? The test for NI Switch Executive panels refer on behalf of virtual device NI Switch Executive, not the DAQmx device name. If you had named the name of the NI Switch Executive virtual device in the same way, that could be part of the confusion of the problems that you see. See the images below:

    NEITHER DAQmx Test selection panel that leads upward.

    Test NI Switch Executive Panel allows this. If these names are similar, I can see how that might be confusing.
