Button to enable all checkboxes on front panel

I have checkbox controls on the front panel to select various functions of my VI.  I would like to have buttons to check ("enable all") and un-check ("disable all") all the checkboxes at once, if desired.  Preferably, I'd like to see the boxes activate (show the checkmark) prior to starting the VI -- like they do when you select them one by one.  I am fairly new to LabView & am using 7.0 Pro.  Any help would be appreciated.

Here's a picture of the code. Pretty simple.

  • Can't scan from 5610 all in one front panel

    I have an HP5610 all in one installed on my Dell Vostro 200 with E6550 dual core processor, XP SP3 home OS. I noticed the problem when I tried to scan from the front panel of my 5610 and the orange exclamation light started blinking. The display said "No Scan Options". I ran the HP Print and Scan Doctor and it said to set the front panel scan destinations. I selected the default settings and closed the HP Direc.exe. When I opened the HP Direc.exe and looked for the panel destination that I set, I saw that they did not save. I can scan just fine using the HP software and have been doing so for many years. I now am wondering if I have had this issue all along, especially since I never remember trying to scan from the front panel of my 5610 until the other day.
    I have done just about everything the Printing and Scan Doctor told me to do. I have shut down my 5610, unplugged it for several minutes, plugged it back in, removed the all in one program and reinstalled from the HP website. What is strange...I have the 5610 software installed on a Dell 3000 Dimension I have in a home network and it works perfectly. I'm seriously thinking about moving the 5610 in the room with my Dimension 3000 and buying a (print only) printer for my Vostro 200. I can work around this but I can't stand to have something not work correctly with a very good computer. Please, no comments on my preferred operating system. I am not upgrading, and as I said, this all in one works perfectly with a PC built in 2004. And contrary to belief, I am still getting security updates on a biweekly basis from Microsoft. One day last week I got 8 in one day. Thanks all for all of your excellent help!

  • How can I close all open subVI front panels, without closing my top level VI front panel when all VIs are built into executables?

    I'm using the code shown in the sample VI discussed here: http://digital.ni.com/public.nsf/allkb/353A696A3F393D9B86256E8B007A2912
    to close all open VIs except my top level VI.  My top level VI is actually a separate executable and the sub-VIs are their own executables.  All reside under the same project.  It works very well if I'm running in LabView but will not work when I build them.  I added all the sub-VIs to the Always Include box in my top level VIs properties which did nothing.  I also tried adding them to the Startup VIs box.  This allowed me to close them all programmatically from the top level VI but it also open all the VIs at once (which was expected and not desired).  I think the problem is the executables are not able to see outside their own memory space so the top-level VI never finds any other open front panels to close.  Is this correct?  Is there another way to go about doing this? 
    Thanks!

    Where do I begin…..
    I’m using a “server” to control 4 “client” PCs.  My server opens references to 4 VIs on each client then executes them sequentially.  So on a normal day, the server will run everything itself and I will have no contact with the clients.  But on a several occasions, I’ve needed the ability to walk up to one of the clients and run just one of the 4 VIs. 
    We are updating from LabView 6.1 to 8.5 and we want to run executables rather than VIs for various reasons.  I have a new VI running on the client PCs who’s only function is to initialize the shared variables and open/close the VIs.  I initially thought of making the remaining 4 VIs sub-VIs but I will loose the ability to run them individually.  I think I would also have to rewrite the VI running on the server since the 4 references it originally opened do not exist.  I don’t think you can open a reference to a sub-VI on another PC.  Can you???
     As you can see, this is a huge mess.  I’m still pretty new with LabView so any help you can provide would be great. 

  • LV 8.5 opens all sub-VI front panels

    Hello,
    Recently I again saw a strange occurrance that has happened to me about 10-12 times over the past year. Here specifically I am using LV 8.5 with the cRIO and FPGA module. When I was running a new RT VI from the developer environment, (deploying to the cRIO) the result looked something like this:
    All the sub-VI front panels are opened, and shown in their reserved or running state.
    None of these VIs are set to show front panel when called or opened, but all are sub-VIs of the top level VI within the project. It seems to have replicated a "Find all VIs in memory, within the project" and then "Show front panel" Invoke. The troubling thing is that this is not really repeatable, when I have closed all the VIs and run the VI again, it is fine. I have seen the same behavior in LV 8.2, 8.21 as well as when deploying to cFP-2120 or when on a Host computer.
    Has anyone else seen this or are there any ideas of what is going on?
    Thanks,
    Mello

    Well now that I have seen to image, I recall having seen this myself.
    Like you, it was when I was deploying to an RT target and I was not able to recreate this behaviour.
    It was either an 8.0 or a 8.2 app.
    So all I can do is confirm that you are not alone, but can not offer a solution.

  • While loop with stop button within event structure locks up front panel.

    I am not sure if this is a bug with my program or a bug within LabVIEW.  If you believe that this is a bug with my program then I will post my program to be looked at.
    The problem I am having is there is a while loop within an event structure that fires when a particular value changes.  Once the "Activate" button is pressed the while loop within the event structure starts going with a polling frequency of 1hz (1000ms wired to the "wait till next ms multiple" vi).  There is a "Deactivate" button that is wired to the stop control of the while loop and an outter while loop that resets the event structure so that the activate button is being listened to again.
    Once inside the while loop, however, none of the button are responsive within the front panel.  The VI continues to run, and only 60% of my CPU is being consumed, but none of the button or scroll bars work.  The only way for me to terminate the program is with the "Abort" button next to the "Run" button.  If I remove the event structure so that the while loop in question runs as soon as the program starts, the front panel remains responsive.  I've inserted probes within the while loop and verified that it is not running prior to the "Activate" button being asserted, and it is running after the assertion of the "Activate" button with the expected polling frequency set by the "wait till next ms multiple" vi.
    Can anyone help?  Do I need to post my code?
    -Nic

    It is typically not a good idea to stall an event structure by placing loops inside event cases. What good is an event structure if it is not free to repond to events?
    Have a look at some alternative solutions, such as in the following link:

  • Button Function Problem When Showing Front Panel of Sub VI

    Good Afternoon,
    I have a created a simplified version of a much more complicated vi to illustrate the problem I am having. Attached is a main vi and a sub vi. The main vi has a boolean which says to open or close the front panel of the sub-vi. This works great. However, the other push button ( " My Button Function" ) on the main vi does not work properly when the sub-vi front panel is being displayed. It is supposed to be a  "switch until released" button. However, if you try to click and hold it down while the sub-vi panel is displayed it acts as if I am clicking the button rather than being able to hold it down? I was wondering why showing the sub-vi front panel makes this happen? And also, if anyone has any recommendations to fixing this problem?
    Attachments:
    main.vi ‏12 KB
    sub.vi ‏5 KB

    What is happening is the loop is running very fast.  It is constantly reading the open SubVI button and opening the subVI if true, even if the subVI front panel is already open.  If you are trying to hold down the other button, the opening of the subVI front panel is taking away the focus from the main VI and thus acting like you let up on the button.
    Maintain the status of the subVI in a shift register and only open or close it if the status changes.  See attached Main VI.

  • Is there a way to use the built-in Datalogging and programmatically log the front panel while the vi is running?

    I would like to use the built-in Data Logging feature. There is the "Log at Completion" option, but is there a way to programmatically make a new log record while running? I looked around in VI server and couldn't find any methods that would do that. Currently, I am grabbing all of the front panel control references using VI Server and if there are any changes, the changed values are written to a log file along with a date/time stamp. I'm mostly dealing with buttons, which simply change from 0 to 1 or 1 to 0, so it's not too hard to visualize what was pressed. It works okay for reconstructing what happened, but it would be much nicer to use the built-in fe
    ature because you can "replay" directly onto the front panel and actually see what the changes were. However, without being able to programmatically make a new log, it won't work for me.

    Jake,
    There are several options here.
    I would suggest using your own code for datalogging. The datalogging you are referring to is primarily for debug, and one shot datalogs of front panel indicators (and controls?), not including graphs, etc.
    If you go to the file functions, you will see a menu for datalogging. These functions will allow you to save your data, as you need it, simply, and in a compact format.
    I recommend opening the datalog file, doing all your file operations, and closing the file before the program is complete. There are several examples of this in the examples database.
    Good luck

  • VI Front Panel in SubPanel reacts slowly

    In LabView 2010F2, I have a VI that has several buttons and other controls on the Front Panel. When I run that VI standalone, it runs very quickly, uses less than 20% CPU, and is very responsive. ALl of the controls react very quickly. But when I put that same VI FP in a subpanel in a small VI, all of the controls in the VI in the subpanel are now running very slowly. There buttons are slow to react. There is almost a 1/2 second delay on the buttons. The CPU is stall down around 25% usage. The hosting VI does not do much and should not be responsible for this delay.
    If the CPU is not very busy, what is the cause for the delay in the reaction of a Front Panel of a VI that is placed in a subpanel?
    What can be done to significantly improve the response of a FP that is placed in a subpanel?

    CPU Usage and Kernel Time do not pudge much during Save All or Clean Up Diagram of large diagram.  CPU usage stays about 25%, Kernel time stays about 50-75% of Total CPU Usage.
    I don't see any reason why LV would show "not responding" under these conditions unless there are some long LV processes that are being executed that include significant I/O delays that do not relinquish the CPU to do other things while executing these long LV processes. If LV was not blocked by I/O (disk) delays then I should see near 100% CPU usage. If LV was being delayed by memory swapping, the I should see less than 50% memory free,

    It is going to take some work to narrow down the possiblitlites since you have presented this situation as an interaction problem.
    Generally speaking there is one hot button that comes to mind and that is the UI (User Inteface) thread where all GUI updates are handled as well as those things that do not play well if left to run in their own threads (property nodes for example).
    SO I would like to suggest you start by trimming it down to something that work good and then start adding stuff back until you can detect the performance hit. At tath point step back and look for contention issues.
    If I remebe correctly you can't post code images so asking you to post images of teh code that does not play nice together is a no-go.
    You could also run the performance monitor.
    THe Trace Execution tool kit should aslo help you get a the root of this situation.

  • Q:How to trim a VI's front panel at runtime?

    The occupied front panel space can be obtained by calling
    "GetPanelImage" via an invoke node. The resulting cluster "bounds"
    describes the union of all front panel objects. The front panel can then
    be resized to fit these bounds. The content of the front panel can be
    repositioned by manipulating "FrontPanelWindow.Origin". This "...Origin"
    points with an _unknown_ _offset_ (which varies with the FP´s layout) to
    the upper left corner of the front panel content.
    How to exactly calculate the origin from other front panel values?
    Thanks,
    TC

    You can use a VI Server to position the front panel of your subVI. Look at the Ghost in the Machine.vi example that ships with LabView.
    To see where to position the subVI, you need to know the position of the calling VI or of something on it. You could use a property node of the Get Details button.
    1. On the front panel on Panel.vi, right-click on Get Details and select Create >> Property Node
    2. Right-click on the Property Node and select Properties >> Position >> Left.
    3. Point to the bottom edge of the property node and pull it down to add another element. That element should default to Top.
    That will give you the coordinates of the Get Details button. Now use a VI server (based on Ghost in the Machine.vi) to place the subVI front panel the desired distance
    from the Get Details button.

  • Vertical Scaling of Front Panel Indicators

    When I use the Window Size option "scale all objects on front panel as window size changes", some objects scale in x and y and others (my indicators in particular) scale only in x, causing them to look wide but short.

    Dear Jeremy,
    Thanks for your help and sorry for being slow to get back to you. I have LabView 6.0. The problem does not appear to be caused by rounding. For example, I have a Boolean button which is sized 72x72, and an indicator sized 137x46. My overall window size is 1159x700. When I increase my overall window to 1448x875 (a 25% increase in both directions) and check off "scale all objects...", the button increases to 90x90 as expected but the indicator increases in length only to 171x46. It's height does not change. This is true for all the similar numeric indicators and controls. Perhaps it is the font size that determines their heights.
    I will attempt to post the vi. I am new to these discussion forums - it appears I should do this as a file attachme
    nt. Hope it works.
    Thanks, Peg

  • Keeping front panel objects aligned on target machine

    I have a simple little program that looks fine on my development station but looks like crap on the target machine.
    Indicators that are aligned on the dev machine are not aligned on the target machine?
    I don't get it, why does it look so bad on the target machine? Worst of all is everyone sees the target machine so it makes me look bad!

    These instructions worked for me:
    - Open the VI front panel. Click in File > VI properties > Windows Size
    - Enable: Maintain proportions of window for different monitor resolutions
    - Disable: Scale all objects on front panel as the window resizes
    Check if monitor resolutions are equals.

  • How can I make sure the text size on front panel will be adjusted by itself from PC to PC?

    In my VIs under VI Properties -- Window Size, I checked the two boxes:
     --Maintain proportions of window for different monitor resolutions
    --Scale all objects on front panel as the window resizes
    It seems that it worked for everything on front panel except the pure text wording that I put there for instruction purpose.  The size of those text stuff didn't get changed proportionally after my application was built and run on different machines so some of them got cut off and looked messy.
    Does anyone know how to fix this problem?
    Thanks very much!

    Hi Andrew,
    Thank you for looking at my problem!
    Both my development system and test system are Window XP. The font size are all set to Normal. What other details do you need to know?
    The text on front panel shows well on my development machine. But when the .exe runs on my test machine, the text size was not adjusted by itself so the text body got cut off.
    I found a way to "fix" this problem: I had to drag the text box down and right so there is enough magin between the text body and the box on the right and at the bottom. I had to try it a few times until it finally shows well on my test machine. However, with those magins, it doesn't look nice on my development machine anymore. Also, I only tried on one test machine, if it looks good on one test machine, will it look good on all the other machines? Eventually my app is going to run on Window 7. I'll have to test that out and find out if it's still going to be a problem. Anyway, I don't feel this is the right way to do it. I hope someone knows what I'm talking about and have a soluction to it.
    Thanks very much!

  • Set front panel size to fit different monitor ( 2 monitors-pattern to 1 monitor-pattern)

    Hello, Everybody,
    I have here some questions about front panel size.
    At first I have create my LabVIEW programs with 2 monitors and run them with 2 monitors, because of this reason I have created a huge front panel with many objects.
    But sometimes I will run the program only with 1 monitor, the problem is, the front panel is too big, I can not see the front panel with all objects completely on one monitor! I know, I can scroll aroud it, but I don´t like this way. I would like to set the front panel size automatically to fit the window ( to differenz window sizes or resolutions), how can I do that?
    I have tried with "Maintain proportions of window for different monitor resolutions" and "Scale all objects on front panel as the window sizes" to finish that, but they did`t work, I can not see the front panel at once on one monitor;-(
    Can you help me?
    regards,
    Johnny

    As noted in the KB article What Is the Difference Between the Options
    "Scale All Objects on Panel" and "Maintain Window Proport..., the "Scale All Objects on Panel causes all the objects inside the panel to scale when the panel itself is resized". If the panel isn't resized, the objects arent's scaled. You may also want to read the KB article How Do I Scale All of the Objects of My Front Panel with the Window Size?.

  • Disable launch of front panel when starting web services

    Hello all,
    This may be a naive question as it may have a simple answer that I am missing, but is there a way to not have all VIs associated with a web service launch (i.e. show their front panel) when you start a web service?  I find this to be very irritating as I have a lot of VIs associated with the web service that I am running and don't want my windows cluttered up with VI front panels that I am not interested in viewing.

    Thanks for the reply, tst.  I was hoping that I would be able to reproduce this on the client side, but unfortunately I can't generate a simple example .  My web service is large and contains a lot of resources to access different variables and it seems to reproduce this, you would have to deploy this onto an RT target.
    Some further insight into the issue - starting a web service on my current target is similar to when you select Deploy All on a virtual folder in a project - all of the front panels become visible.
