automatic change of files to store data

Hello

I have a stand-alone system that works with 7 serial ports.

I need to store a huge amount of data (115,200 Kbaud / port) because the system must continue to work for a week.

In two days, I have a file size of over 500Mbytes. The problem is that I'm storing the data in a .txt file and then, when I want to the process, with the data, the computer laptop can´t open a file so the size.

I can´t find a way in which the vi can change in real-time (himself) the file to store the data.
Maybe the way is to create 3-4 files before the while loop (in which I read the data), and then change the file in which to store the data, but I can´t find a way to do it. With the get_file_size.vi that I know when I need to change the file, but how I have to do without leaving the whole loop? In my view, necessary to ensure that the visa_read.vi works...

maybe better or another format or way to store data?

It does not matter of data loss while changing the file.

Someone at - it an idea?

Thank you

A quick...

  • Automatic generation of file name with Date stamp

    Please see the attached VI. (LV2012)

    What I want to do is to generate a file name in the format: DayOfYear - month - day - year. txt

    The way I coded it, I was able to generate according to my condition. For example today it generated a file name ' 14-1-14 - 2016.txt ' on my computer.

    But the same code when it is run on the client computer generated this: 14-1 /-4 /-016 .txt and, of course, the VI ceased due to the illegal file name. I gues this is because how each computer formats the date, the time information.

  • How can I change the files stored in date order

    In Eudora, there was an option to sort the emails by date. This option is available in Thunderbird?

    To sort the messages by Date, click on the column heading "Date."
    If it is sorted in the order ZYX and want to order ABC, then click again on the reverse Date column header. I always found it much easier to have newest on top, so I can lift the message pane to provide more space to read the emails.

  • Automate the name of file with form data

    We seek to use Adobe sign for our forms of active release in our office - everything is going well so far, I was just wonder if there is a way to change the file name of the completed form using the form data?

    For example, once the form has been signed, it is just registered as 'agree active form' - However, before signing, we find the serial number of the asset and the user, it is associated with. Is it possible for the file name automatically and then say "Okay - USER - active form SERIES" or even simply the username if possible?

    Thanks in advance.

    Hi Matt,

    Who is currently not possible, but is a pretty good enhancement request... I hope that it is picked up for implementation very soon.

  • Move the location of the VM swap file in another data store

    Hi all

    Was in a task to move the 1000 to the file location of VM swap on another data store which is newly assigned to Exchange us to the existing store database file that will be decommissioned.

    Eager to check if anyone has made movement swap of VM location of the files to a data store to another and that all measures taken to move.

    Require some VM downtime?

    Thanks in advance a ton.

    Yes it is possible without interruption of service to virtual machines.

    1. make sure that your cluster is configured to use swap data store specified by host

    2. take a host in the cluster in maintenance mode, change the location of the VM configuration file to point to the new data store

    3. do this for all hosts in the cluster

    When you vMotion a VM from one host to another the swap file will get moved to the new data store. Later when you take guests to the maintenance and return output mode, vMotion occurs for each computer in the cluster virtual and file is moved.

    I use Livecycle ES3 and Adobe Professional XI

    I have a form in livecycle for employee evaluations.

    I'm saving a file based on domain names.  My problem is when I use a date in my file name field.  I have the scripts to work for the confidence function and the button on the form field.  They are listed below.

    Script folder level-

    {
    app.beginPriv ();

    this, "/ c/myfiles / ' + ReviewPeriodTo.rawValue + '-' + Div.rawValue + '-' + EVALTTYPE.rawValue + '-' + LASTNAME.rawValue + '-' + FIRSTNAME.rawValue +

    ".pdf");

    My problem is the ReviewPeriodTo.rawValue.  When I enter data in the form and that you do not enter a value for the ReviewPeriodTo field, the file is saved with the values of other fields, and a null value is inserted where the field would go to date.

    When I type a value such as 2014-03-15 in the area of the ReviewPeriodTo and values in other areas, it works.

    When I try to insert a value in as the 15/03/2014 in the area of the ReviewPeriodTo, I get the following error.

    My problem is, it's part of a much larger process when I import information from a make table query MS Access which is exported to Excel.  If I could just format field data automatically to formation of yyyy-mm-dd since t, that would work, but I don't know how to do coding in MS Access.

    Question: How can I format the data which are entered on the form to be the yyyy-mm-dd format?

    I tried to change the display format and data through models livecycle for the field, but it does not work.

    Any help would be greatly appreciated!

    Thank you

    Hello

    It sounds like you need to specify all the formats users can enter the date in the editing modes.  If it matches one of the formats then the rawValue will be automatically formatted to yyyy-mm-dd format.

    This means that if the formattedValue is equal to the rawValue then the date does not match one of the edition models so you will need display an error message.

  • "move a file of this data store...". »

    I see a white icon in the properties of the vCenter data and store when I go over it, it reads "move a file of this data store to another location accessible to vCenter.    I wonder if I could use this icon to move a VMDK to a VM in DataStore1 file to another virtual machine to the same data store (IE DataStore1) so that the VMDK is now up to the second VM.  I think about it because I need to migrate a virtual 2003 Windows computer to a Windows 2008 VM and the second vDisk in the Windows 2003 VM is strictly a big data VMDK (about 650 GB) drive.  The data store has a capacity of 1 TB with about 250 remaining GB... so I can not copy the file, BUT if I MOVE it so would not create a vmdk duplicate file and I would not approve the data store.   Anyone know?

    There are two files associated with each virtual disk. The disk.vmdk and the disc - flat hard the disk.vmdk is just a descriptor text for the virtual disk. You can read the disk.vmdk with vi or simply use

    cat disk.vmdk
    

    It will point to the disc - flat hard. The EI vmksftools will rename two files vmdk and change the pointer in the disk.vmdk file.

    MV does not change the pointer inside the disk.vmdk

  • I'm scanning several photos and I would like the name of the file to automatically change with every save?

    Whenever I scan a picture I have to change the file name of myself, which is very tedious and time consuming. I'm scanning of thousands of old family photos, and I was wondering if there was a setting that I could use that would automatically change the name of the file without having to type it myself, me as image1, image2, image3, image4 and so on.

    It's a HP scanner and the computer I use is a Dell with Windows 7.

    Unless the scanning software you use supports this feature, nothing you can do or change in Windows will do.

  • automatically changed file format

    HI -.

    I did save work under Windows PCM wav format.  Recently when I save a mix, it is automatically registered as a "16" file - that is, hearing, Windows PCM wav is not an option, but here's what it shows instead: Windows PCM (*.16; *.wav)

    What is and why it is happening?  Also how can I convert to simple Windows PCM wav format?  It has to do with the size of the file? It is 73.6 MB.

    Thanks for the help!

    Thanks, screenshots it's looking like you are using 1.0 or 1.5 hearing hearing (about 13).

    The forum most appropriate for this version is here: Audition 3.0.1 and earlier

    Honestly, I don't know how *.16 entered in the list.  It could happen with an accidental files ending il.16. If Windows may have thought that you were trying to add this extension, when the file had a date at the end of the file name.  An uninstall then reinstall probably fix it, but you will probably not be able to reactivate an old version, if you uninstall (so don't do that).

    Otherwise, it would mean probably through the registry to remove this option *. 16, but it is a complex process.

    The memory on your computer will not be a factor here.

  • How to change the vmdk in another data store

    for my vm four disks are there I want to increase disk capacity but there is no space on the data store

    Hello

    Solution is that you must change the drive to another data store and increase space.

    First findout in spatial data store is avaialble.

    Select the virtual machine and migration - migration datastore - Advanced - click the drive on which you want to increase space - browse - choose data store where space is available - finishing

    After migration - more space.

  • Find files on the data store that have been removed from inventory, but not deleted from the disk

    I have ESXi 4.1 and with vSphere Client to manage virtual machines.

    Some of my users continue to use the 'remove from inventory"rather than the option" remove disc "in vSphere when they want to delete the virtual machine.

    This leaves the computer virtual on the data store but not used. I have since removed this privilege among the offending users but I need to do a bit of cleaning.

    I have a lot of files on the data store where users have done this in recent years. Probably about 150 records but only 80 VM listed in the inventory.

    Is there a way I can output, a report showing the data of each machine store directory in inventory so that I can remove anything not on this list? ID rather not to manually check the parameters of all 80 VM in the inventory.

    Out ideal would be something like:

    MyVmNameHere 1, \MyVmDirectoryHere1\ [DataStore1]

    MyVmNameHere2, \MyVmDirectoryHere2\ [DataStore1]

    A great tool to discover all this and much more is RVTools
