What happens to a file at the end of playback of a file reference?

Question general file IO.

If I'm reading a binary file and the read operation reaches the end of this file, what happens to the file reference?  It exist in memory at this time, or is he out once labview publishes the end of file error?

I coded a "departure" from playback and functionality 'stop' and the 'Stop' button is the only method in place for the closing of the reading file reference.  Immediate sights are

(a) what is happening to the reference of the file once the read operation reaches the end of the file

(b) it is important that I have never close the reference of the file once the user clicks on 'stop '?  (i.e. is it a best practice out there?)

I'm under Labview 8.6 on Vista Business.

The file reference is valid when you reach the end of the file. Each read operation returns an error, but you can write to this location. Writing will succeed because it's normal when you add data to a file.

Close the reference when the user types stop is OK. If you implement a Replay button that you just need to reposition the pointer at the beginning of the file file and read again. This avoids the need to close and reopen the case.

    Because you will lose the lot, you will need to restore from your external backup. If you do not back up your files regularly then it is a good time to review your backup strategy.

    You can always back up your files to boot the machine with a Ubuntu boot CD. Unfortunately, it is much more difficult than restoring from a backup disk.

  • What happens to changes made to the file during a p2v/v2v conversion?

    We are eager to do a V2V conversion on a file server that has a data partition on thick disk of provisioned to get slim with HDD resize.  I started an online conversion (vm under tension) and things are going very well, but what happens to files that are modified on the server while this process takes place?  Virtual machine changes source is written to the destination virtual machine towards the end of the conversion process?  Similar to when you migrate to another host/store data?

    I looked through the converter and the importer a few user guides, but I've seen no mention of this.  They were older documents, I found for esx 3.x.

    Someone at - it a document or advice on this?

    Thank you.

  • What happens to resources when a program ends and garbage

    Hi all
    Could someone tell me what is happening to resources when a program ends?
    Resources such as a "java.sql.Connection' or a 'java.nio.channels.WritableByteChannel" close automatically when an application ends?

    Also, is there some kind of garbage collection that takes place? According to Effective Java 2nd edition point 7, "it is quite possible, even likely, that a program ends without running finalizers on objects that are no longer available." What happens then?

    Thanks in advance!

    As stated above, you must always closed no matter what output buffering stream or writer yourself, otherwise you will lose data. You must close the database connections yourself, otherwise you get a commit or abandoned according to you and the seller may not so get the one you want. (You should be close connections to DBMS inside finally blocks actually and using a pool of connections, not held on them forever.)

    There are a few resources you do not need to clean: you don't need to have windows of Swing, for example, and you have not and cannot have MappedByteBuffers.

  • What happens if you wear on the Apple Watch so loose?

    Electroisolante of the night, you guys guys haz of the indices to see what happens when you wear it on the Apple Watch tight or loose? Please give me the thing to see what is happening

    Ok?

    Hello

    Apple recommends port Apple Watch comfortably on top of your wrist, neither too loose nor too tight and with room for your skin to breathe.

    If you wear too vaguely Apple Watch, the watch can not stay in place, sensors maybe isn't able to perform more efficiently and the group can cause rubbing. For example: with wrist detection enabled, your watch can block several times while still on your wrist, because of the watch to lose contact with your skin and believing wrongly that he had been removed from your wrist. Haptic (cuts wrist) may also be less visible. The heart sensor performance may also be affected.

    Wear the watch too tight can cause a skin irritation or discomfort.

  • What happens when my subscription of Dreamweaver ends, what will happen to my website?

    What happens to my Web site?

    Your software stop working when you stop paying for it.

    Your site hosted on an advertisement, 3rd web server part will not disappear. But you will need to use a FTP Client (Filezilla.org) and an HTML Editor (in brackets, etc...), to edit and maintain.

    If your site is hosted on one of the products Adobe hosting (Behance, Business Catalyst or ProSites), then it will disappear from the radar screen.  Obviously, it is something to consider when choosing a host.

  • ESXi USB, what happens if you then remove the USB boot?

    Hello

    Someone in our team IT wants to use ESXi 5 bootable, i.e. start an ESXi host for a 2 GB USB flash drive in order to save the cost of buying the hard drives local to a RAID set.

    I know there are a few downsides to this, but one thing I wanted to know more precisely, it is what happens to the ESXi if you remove the USB or the USB drive goes down, while the host is running. The army continues to operate, as it will be charged the ESXi image in memory? Or it will fail if it cannot see the USB as it initialized from?

    Thank you!

    ESXi will work on - running some virtual machines are not affected.

    Usually, there should be no problem to plug new - but I have seen cases where the system does not start after a rough unplug - so avoid it.

  • What happens to CS6 license after the purchase of CC

    We recently purchased an Adobe CS6 product and we are planning to upgrade to CC for one of our staff. What happens to the old license CS6 if we improve? Can I still install the suite CS6 on another computer with the license, with which he came, or it becomes null and avenue?

    @Promofuse, as you had CS6 subscription more early then you auto upgraded to creative cloud subscription.

    If you now replaced by subscription CC (single license) as the automatic migration.

    However, using Creative Cloud subscription you can always install CS6 on same machines desktop where you have already enabled subscription (no additional machine).

    Please see following article which explains how to install CS6 applications using creative cloud.

    http://helpx.Adobe.com/creative-cloud/kb/download-previous-versions-creative-applications. HTML

    With regard to your question if you had bought CS6 as set full suite (rather than the subscription)

    then you need to buy the subscription to creative cloud separately (you can choose a special discounted based on CS6) but you will be automatically upgraded as in the case of subscription CS6.

    Hereby, in this scenario, you now have CS6 license of the full suite and subscription CC package (each with activation).

  • What are my upgrade options after the end of support for XP?

    Original title: UPDATE XP COMPUTER!

    From Internet Explorer

    Computers with Windows XP may not have all the drivers they need to work with Windows 7.  Generally, this lack of drivers results in performance degradation, but it could also mean that some of your hardware do not work. For example, you could move the PC to Windows 7 and then knowledge you can't get on WiFi networks more.  This is just one example.

    What you can try is the Windows 7 Upgrade Advisor.  It will scan your system and let you know if she can handle the upgrade.  http://Windows.Microsoft.com/en-us/Windows/downloads/Upgrade-Advisor

    Instead of direct upgrades, most users just get a new computer.  With Windows XP, be 12 years of age, it might be time for a new PC. But if your still works perfectly and doesn't have a big crash of the upgrade, there is certainly no problem with you this.
