  • Table of indexing with a push button

    Hello

    I'm doing a round table where the size of the array is 5. I'm looking for entries if we can do the same thing with them using a whole loop and the timer, but with a push of a button. Attached is the code I'm working with.

    Thank you.

    I used a structure of the event.  Also, I replaced the structure of your business with the Quotient and the rest VI.

  • Update the Table with the push button

    Hi I want to update my table using the push button that requires a transfer of account

    For example a single account transactions into 2nd account


    I used this query, but his does not work

    Update of cb
    Set cb_acc_id =: block3.acc_id_target
    where
    cb_acc_id =: block3.acc_id_source;



    Concerning

    Wasim Ismail

    You may forgot to validate your update...

    BTW:
    your form will not recognize, you start a transaction and make an update in the database.

  • Trying to create a push-button locking with digital inputs

    Hello world

    I am writing a program to control a motor with 3 push buttons, upwards, downwards and stop. I want the top button to lock when pushed and delatch when the stop or down are pushed. I tried the example program Latch.vi REARMABLE of this Web site, but no luck. It seems that out of the gate AND is indeterminate. I have attached to my program, any help would be great! Thank you

    Use Index Array to get the desired Boolean value of the table.  If you do the wiring one index, it will give you element 0.  With this, you can have all the switches wired to different pins of the same registry on your DAQ hardware.  Then, you can read a byte and unravel what bit does what.  You will also need to build Boolean individuale in a table before you write in the acquisition of data.  Here's a quick example:

    You must decide which games to buttons that bit.  I have not yet checked your lock algorithm logic.

  • Why push button and stop button does not work in the structure of the casing and buckle my VI? (code attached)

    I am a beginner. I'm trying to create a simple VI only switches beetween two types of signals like sine and triangle when someone press on the push button and at the same time, save the data in the file to my desktop. I also have a stop button which no longer record data.  Here are my questions and dproblems:

    1. when I press the button, it does not the true and false in the structure of the case so that I can see the triangle wave stops and begins the sine waveform table.

    2 when I press the stop button, I want the program still running, but the process of writing data in time the loop stops. I don't mind if the graph of the wave stops too but it would be better for the user to see the wave form is running, but the data will stop recording.

    3. Although the condition of the loop did not accept the local variable for the stop button inside the loop or within the structure of the case, so I put the button outside all the loops and the structure.  (I know that this is a problem, I do not know how to use a single button several times in a single code. The local variable did not work the world premiere? I have to?)

    4. the data file it creates hase a lot of lines and columns. I expect a time column and a column of mixed signals based on the push button amplititude this user press every time.  I did that with the acquisition of data and a sensor, it automatically gives me the voltage and time in a column. I tried 2D and 1 d and it has not changed anything.

    Thank you for your help

    Like you said, you read only your entries at the beginning, then whatever value they had before you hit run is worth to be seen by the rest of the code. Programming LabVIEW is based entirely on the data flow and parallelism. It is incredibly powerful and has led to its success over the years (coupled with graphical programming), but is usually one of the first things the new developers stumble on. This is a simple resource to familiarize themselves with its functioning. The function to highlight execution is a great way to watch how your application uses data streams.

    Simple code goes like this:

    • Containing the main code of while loop

      • Inside of the whole loop is all user interaction code or modify the code entry
      • Stop the terminal loop is attached to stop certain criteria or user selection of a stop button
    • Loop initialization above all if necessary
    • Closing referrals and communications, etc after all loop

    It's very simple code. If you want to watch in more advanced architectures that are scalable, Google "LabVIEW State Machine" or "LabVIEW producer consumer."

  • change the push button for control or indicator at run time

    Hello

    I have a lamp that can turn into power according to the value of a Boolean variable.

    There are two ways in which I can control the lamp.

    (1) manual mode in which the button must be used as control to change the value of the Boolean variable.

    2 auto mode) in which the value of the variable is changed programmatically. Push button must return to an indicator to indicate the value of the Boolean variable.

    I should be able to swith bw manual and automatic mode for the duration and the push button should switch to control and indicator respectively.

    For those who might wonder why it's necessary: there is a sign which must be controlled in manual/auto mode. in manual mode, operator will manually use the buttons as controls for updating the control variables, in auto mode, my control algorithm updates the variables, and the Organizer must be able to see which button is pressed and when. If the button should be the control of update of variables in manual mode and must be the indicator of the evolution of the variables in auto mode.

    How is that possible?

    A basic VI with three objects are attached, and the Boolean control variable is global.

  • How to control a box of series push button

    Dear Sir or Madam,

    I am relatively new to LabView and National instruments, but try to capture the response time of a human participant.

    A simple example of the tasks that I hope to accomplish is described as follows. I think that first of all, I will write a Labview program to present two pure sounds to the listener (one at a time), with a tone have higher than the other ground. In other words, pure acoustic sounds will be delivered to the ears of the listener through a series of regular computer headset. After listening to the two-tone, work of the participant is to discriminate which has higher ground, then press a button accordingly. My question is in relation to the buttons... It is my understanding that the buttons can be:

    (1) software buttons that are displayed on a touch screen computer.

    (2) physical buttons on a separate reply box which is connected to a serial port on a PC, or

    (3) physical buttons on a separate reply box which is connected to a material OR (an e/s of control map, perhaps!?)

    For some reason, he is I think understand that by using the internal clock of a PC is not reliable, due to the nature of multi - load Windows System. In other words, either by using a touch screen or a serial port on a PC is not a good idea; because if I do this, I use the internal clock of my computer, which can be interrupted by other programs running simultaneously on Windows System. In other words, the multitasking nature of Windows of the system will be inaccurate and unpredictable reaction time. It is also my understanding that, if I want a good accuracy reaction time (for example, down to words maybe 1 or 5 msec!?), I would need to use a separate clock which is designated only for this task. Once again, I'm stretching and trying to accomplish a task that is new to me, and I don't know if I'm not mistaken...

    I currently have several cards to control IO OR in my lab. They are the USB - 6216 BNC, PCI-6221 (with a block of connection BNC-2090), data acquisition 6062E WLS-9215 BNC and DAQ wireless. For the purpose of this new task, I think more on the use of the USB-6216 BNC or PCI-6221, if any at all. NOR sells any push button and related devices? So, I can use the clock inside a card of control of e/s? Or I have to buy a new set of devices?

    If someone could advise me on what configuraitons or options would work best for me this task, I'd be very happy.

    Sincerely,

    Fuh

  • Update Firefox 29 I can't access to the sidebar of history with the history button. Any suggestions on how to change this? I tried to customize the toolbar

    Since the last update I can not access the sidebar of history with the history button more. I tried to customize the toolbar and download the Restorer Classic theme. Neither worked help would be appreciated.

    Does it mean that nothing happens when you click the history button and choose View history Sidebar?

    And nothing happens when you click the taskbar button side story provided by classic restaurateur theme?

    What happens when you hold the Ctrl key and press H?

    If none of the works above, restart Firefox with disabled modules and test again. Of course the button provided by the Restorer of classic theme will be temporarily unavailable.

    the camera shutter sound cannot be silent with the mute button on my phone i 6 s

    Depending on where you purchased your phone, this is not possible, because of legislation in these countries that regulate this feature.

    In all other cases, try to force reboot the phone by holding down the button sleep and home for 10 seconds, until the Apple logo comes back again. You won't lose data, but it can cure some problems after installing new software or applications.

    In the case where this does not work, restore the phone:
