Number of events managed in one case, the variant newval

Hello!

I use a case of event structure, and a value of two handles cases change events. One is a button, the other is a group of controls.

I would like to distinguish whether the source was the button, or one of the controls in the cluster, but I'll be back again-val and old-val in a type variant.

How could I return the appropriate values?

Thank you

To do this, you will use the event "ctlref" terminal, not the "newval".

If you have only two controls, create a command for one reference and compare it with the terminal ctlref event. If they are equal, that had the control, else other. Place the Terminal two controls inside the event to get the values of each.

(If you have more than two controls, create an array of references to the command and use "search table" for the release of ctrlref)

If your controls have unique names, you can also use the ctlref for the label control, for example.

  • Edit event managed by this case in LabVIEW 2013 does not show the specifiers of the event, Event Sources and events on screen resolution 800 x 600

    Edit event managed by this case in LabVIEW 2013 shows not specifiers of the event, Event Sources and events on screen resolution 800 x 600.

    As far as I know, the list of supported resolutions is determined solely by the graphics card. It is possible that one used by the PC supports only 800 x 600 as maximum resolution, even if you plug an external monitor.

    Like Dennis suggested, the recommended option would probably be to develop on another PC and only deploy an executable for the industrial PC. That's what we do with our systems (although not because of this problem, but because it makes sense. There absolutely no need to have the IDE installed in most of our systems).

    Other options:

    1. See if you can get an update of the driver from the manufacturer to solve this problem.
    2. Plug a USB Monitor with its own driver.
    3. Try to hide the taskbar and make the smaller title bar in the hope that the bug manifests.
    4. Try remote access in the PC. I think that some remote access programs allow you to specify custom resolutions that are not affected by the original drivers. Remote Desktop seems to be a likely this option even if it has been awhile since I've used it.
    5. Check the BIOS. I saw at least one industrial PC where there was some settings in the BIOS to control the resolution, but I don't remember the details, and it was quite limited. I think that in this case, you can change the resolution, but then the image does not fill the entire screen.
  • LabVIEW hangs on create new case of event or change events managed by this case

    LabVIEW crashes everytime I open the context menu for a structure of the event and select 'Create new same case' or 'Edit events processed by this case. "

    I'm running sp1 LV2013. I don't know when this started happening. I have supported existing code so I don't know when was the last time I created a structure, but now it happens every time I do either of the above actions. Needless to say that, now that I need to do this, it's rather prohibitive my quality.

    This happened to someone else? I just need to reinstall LV?

    I feel that I have read of what is going on before, but I can't find the message thread.  CHANGE, just found it.  http://forums.NI.com/T5/LabVIEW/major-error-with-event-structure/TD-p/2700869

    With LabVIEW closed, try renaming your LabVIEW.ini to something else (in this way you still have and can restore it if it does not work).

    Then, launch LabVIEW.  It will create a new .ini file.  See if it works.

    If this does not work, please post your original .ini file here.  It would be interesting to see what setting it could cause a problem.

  • Set priority higher for front panel events in a Structure of the event

    Hey people,

    I need some advice on the management of events in Labview 2013... I have a structure of the event which handles events of façade (keys) as well as some user events. User events come thick and fast from an external dll. The data as well as this event gets queued at the start and then traced / processed.

    The tricky part is if there are great number of events of the user, the response to the event of the façade is significantly delayed. I get about 80 events back to back user every two seconds. So, if I press a button on the Panel before every two seconds (2 seconds, 4 seconds, 6 seconds... etc) is obviously the delayed answer as opposed to pushing in multiples of 3 seconds (3 seconds then 6 seconds, 9 seconds...) where the reaction is immediate.

    Now I know labview 2013 supports two prioritres while generating events (high & normal) but the problem is in my case, user events come from a dll using the 'PostLVUserEvent' method that does not accept a priority. And I don't see a way to set a priority for the events of façade (keys).

    Any thoughts on how this can be managed?

    Thanks in advance, best regards, Abel.

    The best solution would be to separate user and events of the FP in two independent loops, but I understand that this may be difficult if the two event classes operate on the same data.

    Another possibility is to use two loops serialized, encapsulated together in a larger loop, each containing a structure of the event: the first, with a short timeout, would manage the FP events and could go out on timeout. the second would deal with all user events and would be forced to stop after a predefined number of events managed or, better still, when a quantity preset time has elapsed.

  • I can set the number of events in the calendar to display in the Page Notifications?

    I have many calendar events every day (15-25), but only the following event appears in my display of notifications.   Is it possible for me to set the number I see?  As perhaps the next 3 or 5?  And then they are updated as events will expire?  iPhone 6 s

    No, it isn't. There are other calendar applications, for example schedule 5 of Readdle, that display more complete information, but it does not include the events 'expired' or has a Setup for the number of events displayed in the Notifications. I don't know either, but you can always check the App store. But to be honest, I doubt you will find one that handles what you are looking for in the notifications. The sight of Notifications is not really designed for the complete management of the content of the app.

  • Click of the mouse on the chart without event management

    Is there a way to detect the mouse click on a chart without event management? My version of LabVIEW database has no events management features.

    Thank you

    Ryan

    Sweet justice.  Because you were a guy standing, my scorn is now much closer to 90/10.  They should really sign make an acknowledgement that you know what you get.  I don't think it's unreasonable to expect basic functionality, and IMO event Structures are pretty basic.  This is why I'm not in marketing.

    Time of experience.  It may be while you are unable to change the structure of the event, maybe you can run code that contains and edit around them.  Here, I use a structure of the event to a mouse event down to the chart.  Normally, I'd put the code inside the occurrence of the event, but maybe you can not change the inside.  Instead, I pass a boolean that is true when the mouse down event fired and pass out the XY coords as well.  You can do something within a structure separated from cases as I show.

    I would like to know if it works.

  • Unexpected behavior with several structures of events manages the event itself.

    Hi, does anyone have an explanation of the following behavior?

    After 'Boolean 2' is enabled and then disabled the program "freezes". You can always pause the program but nothing does.
    For example, by pressing one of the file, Edit, View, project, Operate, tools, Windows, help or any other object inside the VI.

    This happens if I have two event structures who want to handle the same event, even if the flat sequence should be allowed only one run.

    This isn't a bug.

    Structures of the event should be used to handle different events. Given that you have entered your Boolean event in the two structures of the event, the event gets queued both when it occurs. This means one or the other be expected to manage the event and will, by default, lock the application. In the scale-measure of LabVIEW architectures, usually there is a structure of single event that handles all the events and then sends messages to the coast to the rest of the application to manage these events.

    There is a "Table locking" checkbox in the event dialog box which is by default enabled, but you should leave it on because it leads to bad practices otherwise.

  • I need my files to open in the monitor # 2 I usually have some important information about the number of monitor 1. I need the files to alternate when they are open. One in 2, then one 1.

    Kind regards

    How it works is usually the application (explorer.exe is an application) in question is open about everything that monitor his last (final) session was closed the.  Not all applications have this built-in memory, but most do.

    I don't think that even something TO manage multiple monitors (this is what it was built for) will do what you are wanting.  ;-)  I see no way of programming of this type of automation.  ;-)

  • Cannot open my Adobe suite cS6 Master Collection. Adobe Application Manager keeps asking for the serial number.

    I've never had a problem using basic Adobe on my Mac applications. I had this installed since 2012. Last night, when I try to go to Photoshop, Premiere Pro, or one of the Adobe based products the Adobe Application Manager continues on Popping up. Telling me that the trial is finished, I had to sign up to enter my serial number or to make the Trial Version. And I went through its phases by logging provided the serial number, but unfortunately his telling me I have the wrong info set. I've never updated all Adobe based products, I was still able to use this a week before that my mac is running IOS X.

    My panic, I advanced and uninstalled all Adobe products based on my mac to start cleaning, but now that I install their back to get to the entry number series its telling me the error message even to provide the correct serial number. Can someone tell me what I else I could do, it's very discouraging to say the least.

  • I am trying to add my Linux netbook to my sync account, but both my windows computers will not display the "Add Device" button in one of the sync management screens

    I'm trying a new version of Linux on a net book I use to play with non windows OS. In the process of setting up the new OS install I wanted to make my Firefox account set up so that I didn't have to spend a lot of time working on something. I'm no stranger to sync of browser and several of my computers and tablets with a number of different OS tied to the account with little difficulty in including the Firefox of the previous generation of Linux that has been on the net accountant. The problem is now that on both my computers in the main, a windows 7 and a desktop tablet windows 8.1, both running the latest Firefox, I am unable to find the 'Add a device' button in the synchronization of the management screens. This includes browsers built in display options as well as the Firefox manage account page. The first gives me options to disconnect the account, go to the maintenance screen, several checkboxes that you can synchronize to the device name. The management, after the login screen, don't give me options for the disconnect, change password and delete the account. Any help to understand why the add device button seems to be missing from these two devices would be greatly appreciated.

    Please check the version of your Installation of Firefox. (can be found by clicking on the main menu, or by clicking or hovering the cursor over the help button, and then click about firefox in the submenu). According to since how long you configured synchronization you can still use the old version of sync. Firefox 29 has introduced a new (and I would add a lot less tedious) version of sync. See this Mozilla support article for more information on the upgrade of your sync to the new version.

  • Added Yahoo Toolbar and Add-ons Manager no longer shows the extensions one I can't access the function "get addons".

    I added a Yahoo toolbar for Firefox that has been customized for Frontier Communications. I Ghostery installed as an add-on, and she flashed a message that Yahoo toolbar confused its effective functioning and I would like to disable or uninstall the toolbar. I open the Add-ons Manager to do and much to my surprise he now showed no extension at all, but they all seemed still works! All my plug-ins appear when I look on the Add-ons Manager. I checked the "Get function modules and it tries to load but does not succeed." I am running Firefox 10.0.2.

    Please also try to delete the extensions.* files in the right out of the Firefox profile folder. Firefox will recreate the files and information. Please note that at the next startup, Firefox can request permissions, opening several tabs with each tab corresponds to a detected extension. Select allow the installation, click continue, but click on restart only on the last tab. You can also try to leave out the suspects without selecting modules and continue. I hope it will solve the problem.

    Files & Firefox profile folder

    Another way would be to try a new profile. Firefox stores the data from profile/personal separately from its installation folder. If the new profile is correct, you can later copy/replace files of the old profile in it, for example. the places.sqlite who holds history + information of favorites, the folder of bookmarks which has backups dated only bookmarks, signons3.txt + signons.sqlite which are necessary to restore successfully a saved website names to user/passwords etc. Please note that in this case, although it is also possible to copy the extensions it may be preferable to install again via Tools > Modules search box or AMO.

    Hi Carole,

    If you don't want the indicator on the front panel, there are two ways to do:

    (a) hide by: right click > hide indicator. I wouldn't recommend that, because your code is a bit opaque. Having also a hidden just indicator to trigger an event is generally bad design, then why do it, when you can:

    (b) use the user events. Check out this example of user events. While this may seem a bit much for a beginner, it is a widely accepted design pattern and all developers looking at your diagram will know what you try to do right as opposed to a), where he spent some time looking for the indicator...

    Computers that come pre-installed with Windows usually manufacturers come with two product keys.

    Hi, I have a problem with a PostProcess EventHandler.

    My code gets "ID Manager" of a user, search for it in the "employee number" of all users and gets the "display name" of the corresponding Manager to put in the 'Manager' of the user field.

    It works OK when I put the 'full name' Manager for example, in the "First name" field, but if I try to put it in the field 'Manager' (or 'trade for testing), I get a window with this error:

    int firstComma = (displayNameManager.indexOf(","));

    displayNameManager = displayNameManager.substring(firstEqual+1,firstComma); I get "Lucas Da Silva.

    orchestration.addParameter ("middle name", displayNameManager);
