Programatically change control to generate and event...

I add some improvements of the user (anti-screw-it-up functions) to ensure the desired process are executed.

First question: if I have handles by a change of value in a text control, an event (event occurs when you press enter or exit control with the mouse) the event will also occur if you leave the control by changing by programming the focus to another control?

I'll try and put in place a vi temp to test this, but wanted to see if anyone had tried this and if it works or not.  My other option is to set up several instances of the event but I was hoping to use a single case to handle everything.

A few details, I have a test system that tests a product automatically when the product is placed in a cradle and the cradle is put in position and active a prox sensor.  At the end of the test, the system waits for prox sensor turn off before resetting the system.

If a device goes down, there are options to rework and the unit can be retested.  When it fails, a label prints defining failure modes and provides a number of failed series.  When the device is tested again, failing serial number is entered into a text control. I want the sequence of re - test (queued upward at the event) occur when 1, a failing serial number is entered or two a key (with mouse) I'm pretty sure by pressing a button would in turn automatically create the event of change of control of text so my button can no doubt be a fictitious button just for appearances.

When the hole is if the user enters a serial No. failed and don't leave the command and then committed a pump to start the test.  Can I use a function of "empty access/string path ' but the control will continue to show empty as if nothing has been entered until you press the Enter key or the mouse is used to exit the control."

If I can generate the event by changing the focus, then it will ensure that if you enter a failure s/n, the sequence of re - test occurs and if nothing exists in this domain, it performs a first test of time.

A bit long-winded for sure, but any thoughts are appreciated.

Can't really post a simple code that this feature is in my top level vi and I have a very large app justifying download.

Yes, change in focus is the same by clicking with the mouse outside the control.

  • Generates an event on the indicator

    I'm developing a program in which I need to generate an event on the indicator, the project is as we give 4 entries for LabVIEW vi equipment, since these 4 controls are through material I can't generate events on them, so I'm trying to generate an event on the indicators of these controls , but the structure of the event does not respond when I use the value on the display change event. After doing some research, I got to know that we can use the value property (Signaling) to generate events on the indicator, but I don't get how to use it.

    This is the vi in which I train, this is not the project initial vi, it's just the vi to learn how to generate events on the indicator.

    Thanking you

    You create a value of signage as follows: click with the right button on the Boolean value and choose Create > property node > value (signaling)

    If send you a value to this terminal will trigger an event.  For example see the image:

  • Generate the event

    Hi all

    I use Labview7.0 and need to generate the automatic event. This means without any button or mouse move the activity on the front panel, I want to generate the event after each interval of time given.

    How can I fullfill my requirement?

    Kind regards

    Hello

    One way you can trigger the event is to use node property of this control or indicator value.

  • 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.

  • During the installation of software, I forgot to uncheck to change my start page and now it goes to hi.ru even though I changed it in Firefox.

    I was installing software. I forgot to uncheck the checkbox change my homepage. I changed it in Firefox and it always happens. The site is hi.ru and not in English. I checked for any new or unusual software in Control Panel and you will see nothing unusual.

    This problem is on your system Windows 8.1? (Somehow that got post split as filed, that is for certain phones).

    If Firefox ignores the setting of your home page, there are two possible scenarios:

    (1) an extension is the substitution of the implementation in
    (2) your desktop icon is 'hacked' with the unwanted address (in this case, the home button on the toolbar tools and the Ctrl + n would both work correctly)

    As the first step, here's my method of tracking down and cleaning of unwanted modules. I know it seems long, but it's not so bad.

    (A) open the Control Panel, uninstall a program. After the loading of the list, click on the column heading "installed on" to group infections, I mean additions by date. This can help the undisclosed items bundle smoker who snuck out with some software, you have agreed to install. Beware of everything that you don't recognize / remember, since malware often uses sounding names important or innocent to discourage you remove. Out as much garbage as possible here.

    B open Firefox page modules using either:

    • CTRL + SHIFT + a
    • "3-bar" menu button (or tools) > Add-ons
    • in the Windows "Run" dialog box, type or paste
      firefox.exe "about:addons"

    In the left column, click on Plugins. Set essential and unrecognized plugins 'never enable '.

    In the left column, click Extensions. Then, in case of doubt, disable (or delete, if possible) not recognized and unwanted extensions. Remember that all extensions are optional, none come with Firefox.

    Often, a link will appear above at least an extension disabled to restart Firefox. You can complete your work on the tab and click one of the links in the last step.

    Any improvement?

    If you have extra time:

    (C) you can search the rest of problems with scanning/cleaning tools listed in our technical support article: Troubleshooting Firefox problems caused by malware. These scanners on request are free and take a long time to run. If they end quickly, especially if they require the payment you have a serious infection. I suggest the specialty forums listed in the article in this case.

  • Generate the event by timeout

    Hi all

    I have a structure of the event, whose events are all s 'change of the value' of the buttons on the front panel (each of them did switch a light when you click on it).

    I need one of the events to run also in the case where a certain time elapses (so that one of the lights to blink).

    Is there a way to generate such an event?

    I thought about creating a loop timed running in parallel, which generates an event 'false' to each iteration... but how this false event be generated? (it looks like all the events that can be handled by an event structure are generated by human action, such as push buttons, dragging the mouse etc..)

    Thank you, best regards

    It worked, but I had to use a parallel loop as suggested by johnsold.

    Thank you all!

  • Change control Boolean façade of round instead

    I would change a Boolean control of the façade of a square round LED LED programmatically at run time.  I guess I can do that with one of the nodes invoke or property, but I don't know which.  How can I do this?  Thank you!

    As much as I know, that you can not. I think that the property ID of Style seems to indicate that information, but it is a read-only property.

    Variation: use two controls, one round and one square and hide/show you want.

    EDIT: I see Lynn has already suggested on two controls while I was writing my response.

  • I want to control the speed and direction of a motor continuous using labview with pwm

    I want to control the speed and direction of a motor (essentially a toy motor) continuous generating a PWM signal in labview. I'm using L293d motor and exit DAQ-9472. Can I do this without the help of any microcontroller but only a simple labview code and the DAQ 9472 output

    There are many examples on how to generate a PWM on one in the buffer, or on a counter, but that does not support this card.  A 8 a cDAQ chassis also a BNC connector that can be used as a counter as well.  These examples can be found in help > example Finder in LabVIEW.

    Also be aware of your current limiting.  This card can drive a decent amount of current, but it has its limits.  You'll want to put an inline meter to see what is current and see how far you get to it.

  • Action, State and events, CTF files

    Hello

    In my project, I received a labview program that has a main VI and about 100 SubVIs.  Some of the subVIs are named: Action, States and events. And a Subvi is written for each user action. Actions, States, and the screws of events are CTL files.

    Is - any technique of special programming used in labview for any specific purpose? I am a novice in labview.

    Thank you

    Josée Vilas V

    Vilas,

    The .ctl files are custom controls.  Without seeing them, I can't be sure, but I suppose they could be witnesses typedef'ed enumerated (enum).  These are often used for engines of the action and state machines.

    The state machine is a widely used program architecture. There are examples in the design templates that ship with LabVIEW.

    If you have had no training in LabVIEW, the online tutorial are a good starting point.  It would be very interesting to spend a few hours before your dive in your project.
