To end a Subvi after the break (with IMAQdx)

Hello!

So, I need to display a grid on a projector and take a picture of him with a camera. My problem is that I want the program to run as quickly as possible and at the moment I can only show the grid a certain amount of time.

So I would like to confirm that the photo was taken and stop the vi poster sub grille. I thought that by replacing the tempo by a certain time structure

and send the message 'stop' after taking the picture might work but it doesn't.

So my idea was to make a sequence and then send the message to "kill".

I read about the events, but I don't know how to use it and even if it is not too complicated.

The first picture is the main vi and the second, that I want to end.

Hello

Sorry, I don't have that the VI grid is actually a Subvi from the mainVI. You can use a global variable to pass your stop request to the Subvi.

The question is: do you want to stop the Subvi after loop iteration for all four? Or do you want to start and stop the Subvi in each iteration of the loop for?

Here is an example for the second option:

now, it should work. in the first image is set to false - the Subvi 'Grid' will continue to run the shutdown command. After the image was taken at the 'grid' Subvi is hollow arrested the last image.

See you soon,.

  • Determine if the end date is after the start date

    I have 2 date fields in a form.  When I click the button submit, that I'm trying to ensure that the end date is after the start date.

    Here is the code I use:

    var sDate = Date.parse (BackgroundInformation.Background.CheckingDateStart.rawValue);

    var eDate = Date.parse (BackgroundInformation.Background.CheckingDateEnd.rawValue);

    xfa.host.messageBox ("Start Date:"+ BackgroundInformation.Background.CheckingDateStart.rawValue ");

    The message box displays the start date 2014-10-30 but sDate is Nan.

    I tried:

  • After the recovery with CD Satellite C660-1FE keyboard does NOT work

    Hello

    A month ago I bought a Toshiba C660-1FE. After three weeks my HD broke down. I bought a new HD from Western Digital and I replaced the broken HD. I did a recovery of my HD image, so I had to order the recovery disks of the product on the Toshiba site (3 disks, which drive 1 and 3 were the only required for installation).

    Now I have the problem that my laptop keyboard doesn't work. I am currently using a USB keyboard and a mouse to replace my keyboard and the touchpad of the notebook.

    The keyboard of the laptop works fine in the BIOS. Therefore, I hope that it's just a driver issue.

    I have:

    tried to find and install a lot of pilots since the toshiba site, no results.
    tried to change settings in the bios (usb enabled).
    tried to fix the problem by reinstalling all of the computer repeatedly.

    The keyboard seems to work until windows loads. When the system is switched on I can press caps lock and num lock and the green lights will turn on. All this stops working once windows starts is displayed.

    Perhaps another problem in Device Manager: under the graphics card, 2 subcategories have exclamation points: it says Mobile Intel (r) 4 series express chipset family twice! I can't seem to fix these with the drivers I can find either. When I check the settings I have this message (google translate since it is in Dutch):

    + Digital signature for the drivers for this device is necessary, cannot be verified. Possible after a recent hardware or software change a file that is installed signed incorrectly or damaged, or malicious software is installed from an unknown source. (Code 52) +.

    + You must restart the computer for this change to take effect. + (obviously I've tried that too)

    Can someone give me it please help? I'm at the end of my intelligence.

    Sincerely,

    Daniel

    Hello

    Keyboard works in the BIOS, it means that the keyboard material should be ok and the connection between the keyboard and the motherboard is established.

    So, what could be bad? Keyboard driver?
    Hmm, the keyboard driver is part of the Windows operating system and is installed automatically during the installation of the OS
    I would recommend following:
    Go to Device Manager and remove the keyboard point.
    You should see something like PS/2 standard keyboard
    If you see a red x next to this unit, then it means that the keyboard is disabled.
    Usually, you should be able to activate this again (in Device Manager).
    If there is no Red Cross, so I you would recommend the deletion of this keyboard in the Manager list of devices, then reboot the laptop. Usually, the operating system should recognize the device automatically deleted and should install the driver too.

    Select this check box.

    By the way: it is possible that you received a recovery disk wrong which could explain the problems after the recovery procedure

    Please, back up all data before proceeding.

    This procedure will unlock all your user (not system files) files and reset their ownership, permissions and default access controls. If you have voluntarily set special values for these attributes on any of your files, they will be be restored. In this case, either stop there, or be ready to recreate the settings if necessary. Do that after checking these settings that did not cause the problem. If none of that is meaningful to you, you need not worry about this, but do not follow the instructions below.

    Step 1

    If you have more than one user, and the one in question is not an administrator, then go to step 2.

    Triple-click anywhere in the next line to this page to select this option:

    sudo find ~ $TMPDIR.. -exec chflags -h nosappnd,noschg,nosunlnk,nouappnd,nouchg {} + -exec chown -h $UID {} + -exec chmod +rw {} + -exec chmod -h -N {} + -type d -exec chmod -h +x {} + 2>&-

    Copy the selected text in the Clipboard by pressing Control-C key combination.

    Launch the Terminal application integrated in one of the following ways:

    ☞ Enter the first letters of his name in a Spotlight search. Select from the results (it should be at the top).

    ☞ In the Finder, select go utilities ▹ of menu bar or press the combination of keys shift-command-U. The application is in the folder that opens.

    ☞ Open LaunchPad and start typing the name.

    Paste in the Terminal window by pressing Command + V. I tried these instructions only with the Safari browser. If you use another browser, you may need to press the return key after pasting.

    You will be asked your password of connection that are not displayed when you type. Type carefully, and then press return. You can get a warning to be careful. If you do not have a password, you will need to configure one before you can run the command. If you see a message that your user name "is not in the sudoers file", then you have not logged as an administrator.

    The command may take several minutes to run, depending on the number of files you have. Wait for a new line ending with a dollar sign ($) to appear, and then quit Terminal.

    Step 2 (optional)

    Take this step only if you have trouble with the phase 1, if you prefer not to consider, or if this does not resolve the problem.

    Start in recovery mode. You may be prompted to select a language, then the OS X Utilities appears.

    If you use FileVault 2, select disk utility, then select the icon for the volume FileVault startup ("Macintosh HD", unless you have given it a different name.) It will be nested under another icon of the disc. Click the Open button in the toolbar and enter your login password when you are prompted. Then quit disk utility must be returned to the main screen.

    Select

    Utilities ▹ Terminal

    in the menu bar. It will open a Terminal window. In this window, type this:

    resetp

    Press the tab key. The partial order you entered will automatically end this:

    resetpassword

    Press return. Opens a window to reset the password. You do not need to reset a password.

    Select your boot volume ("Macintosh HD", unless you have given it a different name) if not already selected.

    Select your username in the menu option allows you to select the account if not already selected.

    Under Reset Home Directory Permissions and ACLs, click the reset button.

  • Satellite M40-285 - CPU overheating after the accident with water

    Hello everyone,

    I have a Toshiba Satellite M40-285, and 2 days ago, my girlfriend dumped a cup of tea on the keyboard... The computer turns off after a few seconds. Immediately, I put the laptop upside down and disassembled parts. There was some liquid inside (especially inside the speakers under the keyboard and where is the DVD unit). Other parts (CPU, memory, wireless card, hard drive area) were completely dry. I have it with napkings and dry with a hair dryer (later I read that I shoud never use a hair dryer...).

    The turs laptop on one seems to work fine (only the first screen where it says toshiba remains more than normal long (15 seconds or more) before entering windows). But the problem I have is that the CPU gets overheated and the laptop shuts down after 5-15 minits of use. I'm getting attention via the RightMark utility I said "* Core overheating * ' and the temperature always between 45 - 55 c

    I replaced the thermalgrease but the problem remains. The CPU fan works (I think that the two speeds). The heatsink is very hot after the computer turns off (it burns my fingers if I touch)

    What could be the problem? * Is the processor damaged? Can be a problem in the motherboard? *
    I don't know what to don't know because is not woth the money to send it to the technical service, but I can't buy a new laptop now...

    Hey,.

    I m wondering that the laptop is still ongoing and no more parts are damaged. In addition he s very cool that you could fix it yourself and dry. Many people don t know how ;)

    In any case, if the CPU is overheating it seems that something on the assembly or the cooling fan is damaged and must be replaced. Possibly peut t fan run with the highest speed more, who knows.

    Of course, it is difficult to say what is the cause of the problem, but in your case I would try ordering a new fan and the heatsink too. The two parties shouldn't t be expensive and it seems that you can replace yourself.
    So just contact a service provider allowed in your country to order these parts. They can do this.

    Good luck and feedback would be great, I am interested on this! :)

  • File deleted on esxi system after the restart with the last patch (256968)

    Hello

    Since I installed latest patch on esxi (build 256968), every time that I reboot server esxi, I lost the files in / opt and the .ssh folder.

    Before this patch, the files were still there on reboot.

    Do you have any idea what's going on? Is this a new limitation of free esxi?

    I ' am, using this file to VM backup with ghettovcb and everything works fine (until I reload )

    Thank you.

    This is provided with ESXi, there is difficulty set of files, including any of the local VMFS volumes that are kept at the restart. There is a cronjob schedule that works for the configuration files important backup automatically at a local bootbank, which is then loaded after the next reboot, all files created by the user and most likely using the Busybox does not support console will not survive a restart by default.

    If you use the ghettoVCB.sh - Free alternative for backup of VMS to ESX (i) 3.5, 4.x & 5.x , recommendation would be to store the script and all relevant files is the local VMFS volume or on the shared storage (NFS, iSCSI/FC SAN) volume.

    There is a script in "/sbin/auto-backup.sh" that you can actually run to see what files are being backed up, you can easily modify this script to save additional files which will ensure that they are saved on a restart.

  • I have problems with of the Subvi after the use of customized device model

    I used to start my machine personalized customized device model and I got success in the deployment until I started to do more complicated the Subvi.   I am currently trying to convert low FPGA and high ticks to the duty cycle, but for some reason when I add it to the RT VI "Data read of HW" driver, it seems to cause a downtime... ideas? Is a circuit agree? I have added a time delay but I am still having problems. It is a device online, so I'm suspicious of it hogging resources, but am not sure.

    Attached images are meant to be read like this:

    1. the case of the RT pilot ReadDataFromHW

    2. it's the Subvi calling ToDutyCycle SIMStimPWMSubVI

    3 ShiftRegister.PNG is inside the Subvi.

    As a robotician I celebrate early and often (usually by a failure or two...), but it seems that the answer was to transform fundamentally the While loop for a loop with a count of 1 and then remove the additional elements to ensure that each shift register has that one and then right click on the shift registers and convert at the Feedback node...
    I was able to deploy to VeriStand as a custom device and it runs and calculates the factor of use with no problems. WOOHOO! Where - what is celebrate button!

  • Unexpected end of VI after the acceptance of 3 lines of values from a serial port, transmitting continuous data.

    Hello

    I am currently working on the acquisition of data from a unit of 2 balls of hair, installed with a Zilla controller on an electric vehicle. Hairballs allows other devices to the device through a serial port. The option of data acquisition for displays information like speed, tension etc.

    I use Teraterm, a terminal Communicator to start communication with the device of hairballs. After having sailed in the various menus, I can access the DAQ feature that provides data continuously to the status of the various components of the vehicle. I saved the logfile of teraterm (Teraterm - Results.txt). 5B 01 0b C8 03 53 02 39 27 OMFS is, for example, a sample of data from the module of data acquisition.

    When the port is configured to send these data, I close the program Teraterm and run the LabVIEW VI (read and Write.vi series). It accepts 2-3 rows of data (error LabVIEW - 2.jpg In Motion) and then stops. I know there is a message of error involved, but I think that its storage in what concerns the information in the file (this is another problem, I need to resolve, the file is always empty).

    Could someone help me with this problem please. Why the software ends the execution after only 2-3 loops. Sometimes he starts to accept data from the middle (@ 1 0b C8 03 53 02 39 27 OMFS for example) and stops after displaying the it.
