• Reference to the control on the main façade fails the Subvi front is closed?

  Hi all

  I meet a strange bug. In my code, I use a Subvi to control a piece of hardware. The Subvi has commands for all functions of my hardware.

  I changes the value of one of these controls in my main façade by running a reference to a button on my main façade in the Subvi, grabbing the value of the button with a property node, then update the value of the Subvi control using a node property signage.

  This works very well when my Subvi front is open, but does not work the Subvi front closing.

  I am new to labview, so any help is appreciated.

  Thank you

  This event triggers a series of writing for the real hardware. The material is sent only a command when something changes.

  My code is made up of handlers inside functional global variables. In this way, I can send different parts of code of different orders (example: reset and reset) with the events generated by programming.

  The value of the wheel of the page main itself, according to my probes, getting through. It's the Subvi button that is having a problem.

  I work under a certain pressure of time pretty important, so I managed to convince the boss that the front panel of the Subvi open does not violate the requirements of the application. I guess this has solved my isse.

• The quit event structure works when I switch the cdaq to crio

  I changed my structure of producer of written consumer 2009 for use crio in 2010 and my event structure enough work. The event source is the same.

  

  Panel controls raise no events on targets in real time as the cRIO, as these systems have not really accessible facades by the user.  When they do not display a façade, it runs on the separate development of the cRIO system; LabVIEW just give a homogeneous appearance.

• Nodes cDAQ controllers hardware front panel

  cDAQ controllers have a display port: so the panels before lapping screws can be displayed!

  Well, we know that LV RT cannot manage the property nodes réaccouplés façade elements (especially because the screws that typically run on an RT target do not have an active façade at run time).

  Is this always true with controllers cDAQ providing a display port? (for example, 9132)

  If you want to act on the Panel controls front of a VI running on this kind of material (for example, disabling and grizzled CTL,...), it'll work?

  What OS should I chosse to do?

  Hello

  You're right, previously, it was not possible to access the properties of the façade on RT systems. Our new generation of equipment based on LInux RT integrates a HMI "emulator" that allows you to interact with your façade.

• Connection ethernet or GPIB with Keithley 2612

  Hallo

  Here's my situation:

  I'm relatively new to LabVIEW programming and want to install a configuration of measurement with LabVIEW and a SMU double Keithley 2612.

  If I m work myself through Labview Beginners Guides and how to connect a measuring device with the first simple LabVIEW program.

  Since I Don t own a GPIB-USB adapter for the moment, I was thinking of using Ethernet for the EMS connection that gets ist own IP address. The connection to the PC works and SMU SMU ethernet can be remote controlled.

  Here's my problem:

  I can´t find (usable) guides for the installation of LabView via Ethernet.

  My 500 pages book 'Introduction to LabVIEW' (as of 2009) doesn´t have even a hint for an ethernet connection, while the GPIB, RS232 and CAN are covered pretty well.

  Here's my question:

  Should I continue to try to get LabVIEW working on Ethernet, or would it be better to buy a new adapter USB GPIB.

  Does anyone know good Howto for creating Ethernet connections?

  Should I just the bad 'Introduction to Labview?

  The use of Ethernet has disadvantages compared to the GPIB-USB?

  I'm happy to answer additional questions.

  Thank you.

  Download the Labview driver for the series of 26xxA from Keithley web site.

  For a Visa resource string use something of the form: "tcpip::aaa.bbb .ccc. ddd::instr" where aaa.bbb.ccc.ddd is the ip address of the instrument that you can get through the façade or run MAX and auto-le discover.

  When you finally get a USB-GPIB converter all you have to do is change the resource in the form of gpib string: GPIB::XX:instr «»

• I want to authorize adobe digital 2.0 on my laptop

  How do I allow digital software adobe reader 2.0 on my laptop

  If you have still the laptop with ADE ADE installed, run and type ctrl-shift-D (Cmd-Shift-D on Mac).

• 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.

  Aaron

  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

• How run a background app to LV, but retain the ability to shoot to the top of the façade?

  I'm trying to run an application that I wrote in the background on Windows computers I own, but I don't want people using these computers (friends + parents) notice or disrupting the application. However, I don't want that just run seamlessly (property node); I want to be able to call to the top of the front face, when I need to. A perfect example would be to minimize it to the system tray, with options to right click for the loading of the façade.

  There is an example of it being made here, but it's more than four years, so I don't know if there is a newer, better practice to follow.

  Try this:

• Call vi façade update object in a loop of sub - vi running?

  Hi all. I have a call subvi with a "Start the Test" button on the front panel. I spent a control reference for the Start button in a slot - vi which runs in a while loop. The while loop monitors the Start button and other things.

  Problem: Once the subvi tracks, it takes more updates of this start button. My program who never lets all looped in response to my Start button.

  Is it possible that I can do from the subvi take a present value of appellant vi?

  The sub - vi (upper level, LabVIEW 2011) is attached. Please note that I already tried to put the terminal start the Test inside the loop, but that did not help. I put comments in the block diagram and the front panel to help identify problem code.

  I work around this problem by running this whole vi in a loop by calling vi, where I can easily answer button changes. It is mainly a theoretical problem or curiosity now.

  Thank you very much, Richard V

  You should look at the range of synchronization and familiarize yourself with the constructions of the queue and notifying.  These are very useful for passing data between VI.

• How do I programmatically load and show the façade of a vi but NOT run it?

  Is it possible to load and display the front panel of a vi but NOT run?  I start with the AsynchronousCallAndForget.vi from the example finder and inserted a node invoke with the Open FP method call before the starting node the asynchronous call. The vi that I'm loading has the "Run when opened" unchecked and the menu bar IS visible so I can manually click the run arrow. Thank you!

  

  Why do you use the asynchronous call? If you simply open the VI reference, then call the FP. Open method, it works very well. You can then call the VI run method which wait until is set to false if you want to execute asynchronously, it is how we did in ye olde days before we have this fangled tricks "Start Asynchronous Call.

• status of the computer to run LabVIEW 8.6 remote façade

  Hello

  Is there any specific computer to run LabVIEW 8.6 remote panel?

  It's same as LabVIEW 8.6 run?

  Or I just need Internet access? how fast the Internet is to ensure the quality of the programming? Any fine version of web brouser? where could I find info relavent?

  Thank you!

  Cynitha

  The client computer would need the engine to run LabVIEW. The conditions for this are detailed in the LabVIEW 8.6 Release Notes. With regard to the 'speed' internet should be - that depends entirely on the amount of information that is sent. This KB article details some of the browser requirements.

• Façade has stopped working properly on the Qosmio X 300/305

  Greetings and thanks for reading,

  I had my computer not a week ago and since then, I had some problems, especially with a blue screen when I hit the FN key. Research on the problem, I disabled services of Toshiba and eventually found the culprit: hwsetup.exe. Manual execution crashed my computer and it still doesn't work. However, after you install a new version of it, it seems that FN is working fine now. Hwsetup running always breaks the computer well.
  Any ideas what may cause this? The computer is new, so I don't see what I could have done to cause this situation myself.

  Now to the following problem: it seems that the façade has stopped working correctly, the touch of the keys that allow you to launch the application Dolby, the webcam application and also turn on and off the red lights on the keyboard. When I click on the touch keys, all I get is the tone of the speakers, but nothing happens. I guess I have disabled something by mistake. Any thoughts?

  I would be grateful any entry immensely, people, so please share your theories with me. It is such a thin laptop and I can sleep now, it's difficult to to cause these problems... ridiculous, Yes, but I want everything to be perfect because I spent so much money.

  Best regards

  Hello

  > I can't install the flash card value as well as the utility driver package. It's actually the cause of the blue FN screens. I'm really lost here.
  First of all, you should check if the BIOS version you are using is the most recent.
  If this isn't the case, update the BIOS.
  Then, you must install the utility to Support Flash Cards because this utility is necessary, to get other utility Toshiba works.

  Then install the added value package because it contains the Driver TOSHIBA components common that is an essential component of Windows Vista. He will have to make the other original programming TOSHIBA works correctly.
  It also contains the TOSHIBA Flash Cards tool that provides Hotkey function and function of pitcher who starts the keyboard shortcut function and sends the other TOSHIBA utilities.

  If the BSOD will always appear that it is advisable to recover the operating system

• Update problem UI while ICB running callback functions

  Hello

  I have a simple code CVI that aims to blink a LED on the Panel for some time when the user double clicks on a button in the Panel (right). The CVI code is as below.

  #include
  #include
  #include
  #include
  #include «run Fn.h reminder»
  #include

  public static int panelHandle;
  int i = 0;

  int main (int argc, char * argv [])
  {
  If (InitCVIRTE (0, argv, 0) == 0)
  Returns - 1; / * memory * /.
  If ((panelHandle = LoadPanel (0, "Run rappel Fn.uir", PANNEAU)))<>
  Returns - 1;
  DisplayPanel (panelHandle);
  RunUserInterface ();
  DiscardPanel (panelHandle);
  }

  int CVICALLBACK (int, int int event control panel Run,
  void * callbackData, int eventData1, int eventData2)
  {int i = 0;
  switch (event)
  {
  case EVENT_RIGHT_DOUBLE_CLICK:
  printf ("detected event");
  SetCtrlVal (panelHandle, PANEL_NUMERIC, 23.78);
  SetCtrlVal(panelHandle,PANEL_LED,1);
  for (i = 0; i<>
  {
  SetCtrlVal(panelHandle,PANEL_LED,0);
  Delay (1);
  SetCtrlVal(panelHandle,PANEL_LED,1);
  }
  break;
  }
  return 0;
  }

  But is does not work as expected. The State of the led façade is updated that once the switch housing ends its execution. He did update in the for the loop runs. As a beginner, I have no much idea about the programming of the CVI. However, I found the following information.

  http://zone.NI.com/reference/en-XX/help/370051V-01/CVI/uiref/cviprocessing_events/

  http://zone.NI.com/reference/en-XX/help/370051V-01/CVI/uiref/cviprocessdrawevents/

  But I don't know how to use them.

  Any help is appreciated.

  Best regards

  Actually you need not order you found since SetCtrlVal already have an update of the user interface: simply give the State ONE time for the user to see.

  for (i = 0; i<=100;i++)>
  
      SetCtrlVal (panelHandle, PANEL_LED, 0);
  
      Delay (0.5);
  
      SetCtrlVal (panelHandle, PANEL_LED, 1);
  
      Delay (0.5);
  
  }

  A vision a bit in these commands, you found:

  ProcessDrawEvents () will force an update of the user interface, but like I told you this is already implicit in SetCtrlVal, at least for the addressed control. You need to use this command if other tasks in the application would update the values displayed on the screen.

  ProcessSystemEvents () allows the program to honor even user interface events inside a tight like yours: at the present time, there is no way to stop the process until the for loop ends because even if the user has pressed a button to shut down the system would not see this event inside the loop: ProcessSystemEvents () would allow it.

• User interface customized to run at the same time?

  Hello

  My question is about the user interfaces customized for performances with the parallel model. In my current project, we use the parallel model with sockets to the UI and test 4, we have flags of chain for its execution, which displays messages to the user and the other 2 which has the function of a streaming indicator that displays information throughout the test, also showing instances of time. So, in total 8 indicators that display information about the 4 independent runs alongside. Up to now, I managed to create the user interface only for the sequential mode, using 2 simple string indicators and sending messages to the TestStand to the strings through the user interface Messages. My problem is that I don't know how to implement this feature for the sockets to test more.

  Attached images of the façade and the diagram of blog of the GUI as it appears now.

  I am very new to TestStand (I know that for the last month), so I expect that my question and description of cases are not so clear, so please let me know if anything is badly explained.

  I would be grateful for any help.

  Basically, whenever you get a message from UI associated with running (e.g. UIMsg_StartExecution, UIMsg_Trace, etc.), you will need to determine what testsocket the UIMessage applies to and then update the corresponding user interface controls. A way to get the testsocket is as follows:

  testsocketindex = uimsg. Thread.GetSequenceContext (0, frameId_Notused). AsPropertyObject(). GetValNumber ("RunState.TestSockets.MyIndex", 0)

  In addition, once you know where to go a particular run, you can attach to the control Id of this execution (i.e. property of Execution.Id) and just look at the execution Id instead.

  Hope this helps,

• How to debug the program Labview that runs in the target of the RT of a Compact RIO

  I use CRIO-9073 for the acquisition of data from sensors. Program Labview is written in RT target and target FPGA. It is posssible to make step wise execution for the program written in the target RT and FPGA target the way purpose us for the debugging of the program in general OS.

  MJM,

  The only way to use the debugging on a VI wrote to FPGA tools is to simulate running on the host computer. You can then deploy the compiled FPGA code on the target and run your VI RT in debug mode if you use the communication of the façade with the host PC.
