The amount of memory used for data is a lot larger than the saved file size why is this and can I get the memory usage down without splitting up the file?

I end up having to take a lot of high sample rate data for relativily long periods of time. When I save the data it is usually over 100 MB. When I load the data for post-processing though the amount of memory used is excessively higher than the file size. This causes my computer to crash because 1.5 GB is not enough. Is there a way to stop this from happening withoput splitting up the file into smaller files.

LabVIEW can efficiently handle large files, far beyond 100Mb, provided that care is taken in the coding of the loading/processing routines. Here are several suggestions:
1) Check out the resources National Instruments has put together (NI Developer Zone > Development Library > Measurement and Automation Software > LabVIEW > Development System > Optimizing Applications > Managing Memory), specifically the article entitled "Managing Large Data Sets in LabVIEW".
2) Load and process the data in chunks if possible.
3) Avoid sending the data to front panel indicators, using local/global variables for data storage, or changing data types unless absolutely necessary.
4) If using LabVIEW 7.1, use the "show buffer" tool to determine when LabVIEW is creating extra
copies of data in memory.

    If it is the same app for the iPod and the iPad (universal or iPod/iPhone app) and not a iPad only app, the only way is to restore the iPad from the backup of the iPod.  That will wipe out all the app data currently on the iPad though.
    If the iPad is an iPad only app, then there is no way.

  • I lost my Visual Voicemail when upgrading to iphone 5. New phone was set up from itunes backup of iphone4 but my Mac tells me there is an iCloud back up of my phone prior to this date. Will my Vis Voicemail be on this and can I get it on my new phone?

    I lost my Visual Voicemail when upgrading to iphone 5. New phone was set up from itunes backup of iphone4 but my Mac tells me there is an iCloud back up of my phone prior to this date. Will my Vis Voicemail be on this and can I get it on my new phone?

    I see.  Apple's documentation on what is included in the iCloud backup doesn't explicitly say that it contains voicemails, but that doesn't mean it does not.  You would just have to try restoring the backup to find out. 
    To restore to your iCoud backup you have to start by erasing the phone.  Go to Settings>General>Reset and tap Erase All Content and Settings.  Then go through the setup screens on the phone and when given the option, choose Restore from iCloud backup.  You will then sign into your iCloud account, accept the terms and conditions, then choose the backup you wish to restore from.  To see an older backup, you may need to tap "Show older backups" (see image below).  Be sure your phone is connected to wifi and your charger as this may take some time to finish.
    If this does not recover your voicemails, you can check to see if you have an older iTunes backup that may contain them.  Available backups are shown in iTunes Preferences>Devices on the Backups list.
    If all else fails, you could try contacting your carrier.  Voicemail is a carrier feature and they may have an archive you could access.

  • HT1399 When I import a CD to itunes, it splits the album in to multiple entries. I have changed the info on some but others just will not merge. Is there an easy way to do this and can I stop them from splitting in future? Thanks

    Okay this is what fixed my problem. Some kind of error/glitch occured half-way through importing that third cd that prevented further imports from any other cd. Once I completely removed the half-imported cd album from my library I could further import cd's without any problems.

  • Experiencing trouble syncing with the 10.3 version of iTunes on my Windows Vista machine. Have uninstalled all Apple software twice, reinstalled and continue to get an error 7 message in connection with the Photo Processor. Any other ideas to try?

    Experiencing trouble syncing with the 10.3 version of iTunes on my Windows Vista machine. Have uninstalled all Apple software twice, reinstalled and continue to get an error 7 message in connection with the Photo Processor. Any other ideas to try?

    Hi,
    got it fixed! My Son had both files on his Win7 iTunes installation. Never mind he had no issues whith ths iTunes and iPhone Sync. So I checked my other Win XP PC, where I don't have this problem syncing my ipad, and surprise. Both files do NOT show up on this PC. So I renamed the iTunesPhotoProcessor.exe I found under c:\program file\iTunes and synced again my iPhone and it went through without any error. So the problem might be and unremoved iTunesPhotoProcessor.exe or the missing iTunesPhotoProcessor.dll under the iTunes install root folder and this even if I had checked that the folder was completely removed during iTunes unistall.
    Please try yourselve and just rename the iTunesPhotoProcessor.exe to iTunesPhotoProcessor.exe_ under c:\program file\iTunes or get a copy of the missing iTunesPhotoProcessor.dll and cp to c:\program file\iTunes.

  • The music on my iPhone for that I downloaded is not going to my iPhone five why is this

    I have bought songs on my iPhone for an iPod touch and when I go to set up my iPhone five the songs that I had downloaded some of them had not come to my iPhone five and I will have to repurchase then why is this problem currently has happened to me before I have just repurchased the songs three or four times

    I recently got a new  iPhone, and after restoring all my stuff from my old iPhone via the iTunes restore thing, I had to put all my music on manually, instead of it being restored.
    iTunes content is not included with your iPhone's backup - no music, movies, tv shows, podcasts, audio and print books, tones, and apps. All iTunes content must be transferred back to your iPhone when restoring. If you sync music with Sync Music selected under the Music tab for your iPhone sync preferences with iTunes, music is transferred back to your iPhone from your iTunes library when syncing - syncing is followed after the iPhone is restored. If you manually manage music and videos with this selected under the Summary tab for your iPhone sync preferences with iTunes, you must manually drag all music from your iTunes library back to your iPhone. Manually manage music means manually all the way.

    Probably you have another date format. Open System Preferences > Language and Text to change the time format

  • Ive downloaded ff4 now i cant scroll the web pages using my mouse i have to use the scroll bar why's this and can it be sorted?

    i cant use the scroll function on my laptop mouse pad after i downloaded ff4. i have to use the scroll bar on the page its self

    Have you looked for the file in the location as suggested by the post above mine in the linked thread?
    C:\Windows\System32\tp4table.dat
    Or, if you have a Synaptics device, the file might be located in its installation folder, e.g:
    C:\Program Files\Synaptics\SynTP\tp4table.dat
    If/when you find it I think the syntax should be the same. Either way; you could just change it back if something goes wrong and knowing the file name/location will let you search the internet more effectivly as this is a likely cause.

    I tried everything in your reply,,, thank you again,, I had done that once before and all was working great,,
    I have just now tried the Reinstall via iTunes, about 20 into the download, the iTunes logo on the phone disappeared, and the Apple Logo appeared again,,, I waited until the iTunes stated that the download had finished, and the install was in progress,,,
    Nothing happened, still the Apple Logo was visual on the screen, iTunes never recognised the phone which it was on my iTunes account previously,,,
    Still just a bunch of lines, maybe 5 or 6 so small writing,, I personally can not read what it is telling me, someone said it reads, incorrect shutdown,,,????????
    Please advise,???
    I am now at a loss,,, I really became excited when I saw the iTunes icon after putting the phone into restore,,,???

  • I have a Macbook early 2008 version, I see the new OS will not run on my computer? Why is this and can I fix it?

    Is there anything I can do to update my Macbook to OS Mountain Lion or am I at the last operating system?

    It's because your hardware does not have a 64-bit EFI boot ROM. There is no fix except to sell your computer and buy a newer model that is compatible:
    Macs that can be upgraded to OS X Mountain Lion
    iMac (Mid 2007 or newer)
    MacBook (Late 2008 Aluminum, or Early 2009 or newer)
    MacBook Pro (Mid/Late 2007 or newer)
    MacBook Air (Late 2008 or newer)
    Mac mini (Early 2009 or newer)
    Mac Pro (Early 2008 or newer)
    Xserve (Early 2009)

  • TS1424 I paid for and downloaded a song, but the whole song does not play. Why is this, and how can I get it back without buying the song again?

    I bought and downloaded a song, and the whole song does not play. Why is this, and can I get the whole song?

    Depending upon what country that you are in have you tried deleting and redownloading it via the Purchased link under Quick Links on the right-hand side of the iTunes store home page on your computer's iTunes ? If you aren't in a country where you can re-download music or if it re-downloads in the state then try the 'report a problem' link from your purchase history : log into your account on your computer's iTunes via Store > View My Account and you should then see a Purchase History section with a 'see all' link to the right of it ; click on that and you should see a list of your purchases ; find that song and use the 'Report a Problem' link.

  • I have two excel files I cannot open or delete from my desktop.  One is titled 6ACAD200 and the other file is titled 8D73A700.  How can I get these off of my computer?

    I have two excel files I cannot open or delete from my desktop.  One is titled 6ACAD200 and the other file is titled 8D73A700.  How can I get these off of my computer?

    From the names I'd guess they are temporary files. If excel is running, quit and try again. If they still won't move or delete reboot. If they still won't move or delete...kill a chicken at midnight under an oak tree?
