• 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.

• Initialization of controls on the front

  Hello

  On my front, I have several controls that the user must set before executing the program. The user mostly enters values that each time that on the front before running the program.  Is it possible to save these values in the control on the front panel, so that the user sees every time when the opening .vi program file?

  Thank you

  Mary

  Together the values that you want to be default then select the controls that you want to contain the values and then go to edit and select current values are lacking.

• 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.

• 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.

• 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.

  

• Bringing the master page in the front and sub navigation menu

  Hello

  I have two problems with my menu. I have my menus in a master page which was pinned to the top of the page and 'sent to the front', but when you view the pages with that master has been applied, the menu goes behind the content of the page. Is there a way to automatically move the master page in the face? Or do I need to copy and paste my menu for each page manually to adjust its location in the layers panel?

  

  

  This effect can also be found on Forecaddy

  My second question is the State of the menu 'active' for void menu items. When on the page projects of active state is how I want, with the grey wire dark around the item of menu "projects".

  But after clicking on a submenu item, I want the item menu 'projects' to stay active

  

  Is it possible to do it automatically using the menu widget?

  Thank you very much for your help!

  To answer your second question:

  • To change the active appearance of the menu items, you must change their appearance of States.

  To do this:

  • Double-click the master page that contains the menu widget
  • Click on the widget to select the full menu.
    
  • With the selected menu, move your cursor over one of the menu items (home, About Us, Contact us etc) and click on the menu item and view the States Panel.
  
  
• You can use the States Panel to modify the appearance of:
  • Normal: inactive appearance that people will see when you do not see the page.
  • Turnover: the appearance that you will see when you move the mouse over a menu item.
  • The mouse down: the appearance when the mouse button is in the "low" position (clicked).
  • Assets: the appearance of your menu item have when someone visits this page.
• Click the active state, make design changes required to select.

Note: By default "Edit together" is enabled for widgets menu, this means that the States of this edition a menu item will automatically apply the same setting to the rest of the menu items.

To do this change the behavior edit together:

• Click on the blue arrow at the top right of the widget to display the options.
• Select or deselect change set.

• Volume controls on the keyboard after the upgrade to Windows 8

  I have a Touchsmart 520-1070 with the mouse and keyboard without wire factory.  After the upgrade to WIndows 8, the volume controls no longer work.  I tried the Recovery Manager to reinstall the keyboard drivers, but there is no driver keyboard under hardware drivers.

  In the following device manager are listed under keyboards:

  HID keyboard device

  Keyboard 109 MCIR Microsoft eHome

  Keyboard MCIR Microsoft eHome

  Microsoft eHome key remove control Keayboard

  PS/2 standard keyboard

  Any report that they are installed and are working correctly and that the drivers are up to date.

  Has anyone else seen or solved this problem with a Touchsmart computer?

  The instructions below were provided by HP support.  This has restored the function on the keyboard volume controls.  The referenced below drivers are drivers IDT high definition Audio Device.  I am not sure that it was necessary to reinstall the audio drivers.  It can only had to remove the USB dongle and back to restore the functionality of the button.  Note: the USB dongle is located behind the VESA Panel to the back of the PC.  No tools are required and the dongle can be removed and replaced without shutting down the PC.  VESA panel removal requires a bit of a steady hand, pulling the lip which is close to the connections on the rear panel.

  Instructions received from HP:

  Please go to the following link and check the "return of the system", article #7 is the USB dongle:

  After you have reinstalled the receiver, please download and install the following driver:

• 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

  
  

• How to make a ComboBox that make the active control on the page?

  I have a ComboBox and a button on my page.  I managed to make the default command button. However, I need the comboBox control to the active witness, which means, when the page is finished rendering, the cursor is inside the ComboBox text entry, so I can start typing.  I don't want to have to click in the part of text, and then start typing?

  Note: I tried. setFocus(), who control 'focus', but the cursor does not blink inside the comboBox, I need to click inside the text input for the area of text to "relive" and let me start to tap into it.

  Note: The comboBox control is parented by a Panel.

  Is this a problem of starting time?  Browsers do not activate the Flash Player until you click anywhere in the SWF file.  There is a way to deal with this in IE, but not all browsers
