• How to make non-visible control on the Front Panel appear at Design time?

  I have a few controls on the front whose visibility is changed (on or off) at run time. The problem is that if I stop the Run time, the visibility of the control remains in the running in design mode state. So I am not able to see or find the control to make changes in design mode.

  How can I make all the visible front-panel controls, or find and make it visible to a control on the front whose visibility has False?

  Thank you.

  It is documented in the help of LabVIEW.

  Hidden front panel display

  
  

  Perform the following steps to display a hidden front control or indicator. You can also hide the indicators and controls on the front panel.

  1. Find the terminal block schema for the object. "If you have multiple devices with the same type of data, right click on the terminals and select visible elements" Label in the context menu. Find the object with the label that corresponds to the object hidden façade.
  
  
  2. Right-click in the Terminal, and then select Show Control context menu if the object is a control or indicator to show if the object is an indicator.
  
  

  You can also use the Visible property to display the controls and indicators by program.

  You can also view all hidden front panel controls and indicators.

• no active controls on the front after sub vi opens

  Hello

  I have a little difficulty with my VI.

  I run a sub my main façade of VI VI.

  The sub VI opens, but when it is closed all of the controls on the front of my main VI is no longer active (buttons etc. not clickable).

  I put counters on the iteration of loop terminals so I can see that the program is still ongoing, some controls no longer work.

  Someone has encountered this before and offer all the solutions?

  Thnaks for the research, I appreciate it!

  See you soon,.

  Hello

  Sorry sub VI is located in the loop of the selection of the files offline at the bottom of the block diagram.

  After playing with it for hours last night, I seem to have sorted by deselecting the option "front lock Panel" starting from the properties of structure of event!

  Thnaks for all your help!

• How to show or hide a control on the front

  Hi all, I review the code to someone else, and a control at the front panel seems to be hidden until click you on an item to display. I tried to use right click in front panel and it did not work by clicking something bound to show or hide. Since I did not quite familiar with property nodes, this hidden parameter can be linked to it.

  In the photo, it shows the façade and its two property nodes, could someone advise me how to change the setting to show this control? Thank you!

  

  Hey.

  Is that what you are looking for...

  

  The Visible property to set the option above by programming.  If you want it to, you need wire a real constant itself.

  Kind regards

• Disabling the controls on the front panel

  Hello

  Currently, I am working on trying to disable/gray out between 10-20 controls on the front panel when you press a start button and then allowing them the end of the test. Currently I use the property nodes, all of which are connected to a constant of the State in which I want that works perfectly. My question is that there is another way other than having a bunch of knots of padding property to the top of my structure of the event. Ive read where people had Subvi, which has used references to make this same feature, but is there a way of doing things in the block diagram of my current VI? Thank you!

  Need references of your controls on the front panel, so this can be fast, because you can select more than one, and with a right click you create references.

  I have attached a version LV2010.

  Edit: another review:

  Must be created only once these references. Usually, it's comfortable group all the references in a cluster, use this thread through your entire code. This way you can just ungroup references to the actual location, you have to play with, put them in a table and use the above FOR loop to change their properties...

• 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.

• Outsourcing of the controls on the front panel for a panel floating Subvi

  Hello!

  I already found a few similar topics, but I still don't know which is the best way to solve my problem. I will try to describe my problem in detail first: I have a main VI that acquires data from a device and displays these data in a large waveform graph. I have also a few controls on the front panel to control my device. First, I placed all of these device controls (digital, sliders, etc.) as well as the chart inside the front of my main VI. However, due to limited screen space now I would like to make the largest possible graph and so decided to "outsource" some controls out of the main façade of VI to several panels front-end Subvi.

  I would then press a button in my main VI and it would open the Panel before the floating of the Sub - VI corresponding with outsourced controls when required. However, everything must be absolutely transparent. It is important that floating panels to run in parallel with my main VI, that is the main VI must continue to operate. That way I'll have my data constantly updated in the chart in my main VI while I can change some settings of the device through the controls placed in my SubVIs. These changes will be immediately applied (for example as soon as the main VI calls this slot - VI in its main loop).

  It is important to the visibility of the outsourced optional control panel, i.e. If the Subvi front panel opens with the user that it will pop up and the user will be able to change the paramers device using the. But then the user should be able to close the front panel (hide) the Subvi to see the entire chart again without the Panel floating in front of her (of course control values must be maintained when the Subvi front is not visible). Then the new button is pressed in the main VI that opens the dialog box not modal Subvi containing controls and it can redefine new values of device.

  Advice how to do this are welcome. I don't know if I need something complex like VI server or asynchronous screws or I can solve my problem by changing some settings simple Subvi? Thank you in advance for your help!

  Best regards

  How about using a global variable for the VI at VI communication instead of a queue?

  A global variable will, also.  Write you in one place and read the value frequently to somewhere else (in the election). So you can see easily to any value change.  However, mark will waste a lot of time processor.  This is why I have proposed to use a queue or a notification utility.

  Would be the last option that you mentioned, i.e. finish the Subvi at each change of value, I would keep the Subvi front open as needed until things from the user to hide? Or would there be inevitable flickering Panel or any other drawbacks?

  Yes, the Subvi can keep the façade open until the user closes. And there should be no flickering.  The biggest drawback I see right now is that when you expect an event in the Subvi, the mainVI cannot stop without talking to the Subvi to stop.  So you'll need another channel of communication (again a global, a queue, a declarant or an event) to tell the Subvi that she must stop.

• Binding the controls on the front panel programmatically

  It seems that Programmatic binding the controls on the front panel do not work when they are located in a tab control.

  Is this a known problem in LV 8.6?

  If the control of the façade is already bound to a URL of PSP you can link to another URL using DataSocket URL property during execution of the VI.

  

  If the front panel control is not bound to a URL of PSP, then you cannot attach it to the URL of the PSP when the VI is on. You can use the method AttachDataSocket of VI to change the link while the original VI is stopped (in edit mode).

  

• Best way to reset all controls on the front panel except one?

  Hello world

  I have an interesting problem, whereby I need to run successive tests using a test station which has several indicators on the front panel. At the end of each test, I need to reset all to default values, with the exception of a control (Test ID) who needs to keep his information - its value is used in an initialization status for test to ask for information from a database, so it can not be reset with the rest controls.

  I post all orders at a time using a reference ThisVI and VI Default Vals.Reinit All method, but this will obviously reset my control values (Test ID) as well. Any suggestions on how to keep properly or may store this information control while resetting all others. I can reset individually others but there is a little and more can be added as this system is developed.

  I don't really know what is the right way to proceed, and Labview has maybe one trick in his bag that I know to work around this problem.

  Thanks in advance for your suggestions,

  Alex

  Flank the node invoke with two nodes in the value property of the control to maintain the value. To the left we read as well as a right and the wires together. Connect three nodes with a thread of error to establish the order of execution.

  First reading place value on the wire, which is then written after the values have been reset to the default value.

  

• Using the 'current default values do' as a control on the front panel

  Hello

  I'm building a VI that uses a lot of digital controls. I want to use "do current default values" as a control Boolean on the front panel for the user.

  Is it possible to implement when the program is running? What would be an alternative, if this was not possible?

  Thank you

• Is there a more efficient way to use the visible property node to make the inactive/hiding controls on the front?

  I just inherited the labview code to run a system of imaging optics mamography.

  It has 32 sources 128 detectors and 2 games of light and the user has the possibility to control the parameters of gain for each sensor to each source for each source of wavelengths, so as you can imagine there are a lot of orders and LEDs on the front panel.

  The user also has the possibility to choose the number of sources and that they would like to use detectors.  v: * {behavior:url(#default#VML) ;} O'Bryan: * {behavior:url(#default#VML) ;} w\: * {behavior:url(#default#VML) ;} .shape {behavior:url(#default#VML) ;}}}} Normal 0 false false false MicrosoftInternetExplorer4 / * Style Definitions * / table. MsoNormalTable {mso-style-name: "Table Normal" "; mso-knew-rowband-size: 0; mso-knew-colband-size: 0; mso-style - noshow:yes; mso-style-parent:" ";" mso-padding-alt: 0 to 5.4pt 0 to 5.4pt; mso-para-margin: 0; mso-para-margin-bottom: .0001pt; mso-pagination: widow-orphan; do-size: 10.0pt; do-family: "Times New Roman"; mso-ansi-language: #0400; mso-fareast-language: #0400; mso-bidi-language: #0400 ;} "}

  Depending on how many sources are entered labview code through a loop For which in fact a 'smooth box' visible or invisible, on the adjustment of gain control depending on whether the current detector is greater than the seizure of the number by the user.  This loop slows down the program because it works 128 times (max number of detectors) and has 4 structures deal (2 sets of wavelengths, 2 for each breast) with 64 nodes of property each where it is visible property to enabled or disables the box with that covers the detectors.

  I was wondering if there was an easier way to enable or disable controls for unused detectors, not only that slows down the program but to reconfigure the data to use more sources, I stop the program and restart it.

  Any advice on the creation of a dynamic front would be appreciated

• increase the vertical size of the control on the front

  Hey,.

  I want to increase the vertical height of digital controls in front, but while doing so I don't want to increase the distance between the buttons increment and decrement of control.i tried to increase the height, but by using the node.but property which I find after some limit the distance begins to increase. I have attached to my account. If this is not possible. suggest me a way to increase or decrease the value of controller using large size as shown in the following file separate buttons.

• Functional global variable home (RFGV) is cut off by the controls on the front panel

  Hello

  I though that I had found the ultimate way to dynamically manage memory in a system of Exchange. I read on RFGV here: http://labviewwiki.org/Functional_global_variable and put together a static FGV normal to follow the references for each created instance of memory which I then could easily remember just by name. But now I found that all the RFGV completely stops whenever a front panel with a menu control is used, i.e. 'enum', 'ring' or 'control path. I tried to put in different delivery systems, but not luck. I read about that guy who could have fallen into the same problem: http://forums.ni.com/t5/LabVIEW/Do-I-need-to-use-a-semaphore-when-reading-writing-a-functional/m-p/1... but he got no help what I could see.

  I have not tried semaphores. Don't know what that is. Check my little test code and tell me what I am doing wrong. Or maybe there is no solution in this case I have to abandon the idea of the use of RFGV for anything. Maybe memory held all the VI will be assigned statically.

  Run the code (in LV2009) and watch the 6 LEDS Flash. Then click on anyone of 'enum', 'ring' or 'path' (the file dialog box) and watch off LED when dynamic memory is used to write or read while the continoues to static VI.

  Any suggestions?

  Best regards

  If the memories are good, what you're running against is not the user interface thread, but an internal mechanism of LV called the loop of the root, which must run in some things. Specifically, in your case, the method run a VI and showing a menu (a menu real, or a context menu of a ring).

  You can work around this problem (and greatly simplify your code) If you use the call node of the reference instead of the method to execute a VI, but I wouldn't recommend it anyway, since I assume that your code is not what you think it does. In LV memory management can be quite complex if you want to be able to control it, so if you feel you really need, I suggest to start by searching for existing materials on the management of memory in LV
