I have to save data coming at the rate of 50 ms.i am trying to store the data in an array.from this array, i have take last 60 minutes of data and store in excel. But i am not able to build array to hold the incoming data.

data comes at the rate of 50 ms. So this data has to be stored in a temprorary location say array or circular buffer.After 60 minutes, the new data should append at the last value and the first value should be deleted. Please help.

First thing I would do is search the examples, there are a couple seamless acquisition examples that ship with LV that should do the trick for you. Working in your favor is the fact that you aren't needing to sample incredibly fast, or collect a huge amount of data.
However, typically managing arrays in LV isn't very hard. What specific troubles are you having?

    Oops, I forgot a step between 7 and 8 ... before syncing the iPhone I need to explicitly send the document back to iTunes on the iPhone, or the changes won't come over at all ...
    and then one more thing ... Numbers on iOS does NOT recognize a number of key features of the OSX app, such as conditional formatting ... so after editing my document on iOS and syncing it back to OSX on my Mac, all of those settings are lost (no more conditional formatting, have to do it all over again)
    What am I doing wrong ?

  • We have migrated data from virsa 4.0 to grc 10.1, all virsa mitigation approvers and controllers got migrated but we are not able to map new mitigation approver and controller to the mitigation ids.

    Hello All,
    We have migrated data from virsa 4.0 to grc 10.1, all virsa mitigation
    approvers and controllers got migrated but we are not able to map new
    mitigation approver and controller to the mitigation ids.
    The steps we have done below.
    1. We have created user id in su01 with necessary authorizations
    2. we have declared this user id in Access control owners as a
        mitigation approver and assigned to the organization unit
    Now we are trying to map to newly created mitigation approver to the
    mitigation id but we are not able to find that approver id for the mitigation ids. (only old mitigation ids came from VIRSA only we are able to see, not able to add new mitigation approvers / controllers to the mitigation ids)
    Kindly check this issue, this is very critical for us.
    Thanks in advance.
    Regards,
    Karunakar

    Hi Karunakar,
    - Assign Owners to Organization unit
    - Make these owners as Mitigation Approver and Monitor
    - Create Mitigation Id in this Org. unit

  • Greetings, I am working in Final Cut Pro 7. In the timeline some clips show as offline. I tried going to sequence and reconnecting to media but it does not work. I can still see the video in the timeline and work with it. It just has the red box.

    If the clips are not actually missing, you could try to refresh the timeline by using cmd-0 and then going to the timeline options tab. Then select name only where it says "thumbnail display". Press ok to accept the change, then repeat the process to add thumbnails back to your timeline.

  • I need to use agilent34970A with serial cable;but i'm not able to build a routine.

    Hi, i'm learning labview and i'm not able to build a routine to communicate with my Agilent34970A with serial cable only and to use the data. Anyone can help me? thanks. lucky

    Are you using the driver from the LabVIEW Instrument Driver CD or that you downloaded from here? If you are, what problems are you having? Are there error codes generated and what are they? Have you verified that the serial cable is correct and the the comm parameters (baud rate, stop bits, etc.) are the same in the program and the instrument?

  • I purchased several songs and they are not showing up in my purchased file. Tried to go online and re-download them but ITunes is not giving me option to download only the ones I am missing. It *****

    I contacted Itunes and they told me to go to my account and re-download the songs. I opened my account and found the recent purchases, but they are not recent, there are 250 songs in that list, how come? And ITunes didn't give me an option to download only the ones I am missing. I don't want to download 250 duplicate songs.
    The Itunes updates are worst each time, BTW, Just starting to get sick and tired of Mac and Apple and Itunes and all this complicated stuff because of your paranoia of people "stealing" songs, but in fact, who is going to download songs ilegally is going to do it anyway, So all you are doing is to make it difficult for honest people who actually buy the songs and can't have them. I reported the problem several times and didn't get any more answers. Hope this works before I disoute the charges of the songs I don't have.

    Hi samfergs,
    I'm not sure how the Purchased Playlist decides what to put into it, but if you want to see all of your purchased items, then you need to go to the iTunes Store, and on the right side, under Quick Links, click on Purchased.
    Then, click on the Music (or whatever other purchased items tab you want to look at). If you are looking at Music, click on All Songs, and then on "All" or "Not on this Computer" (depending on what you want to see).
    Cheers,

  • I attempted to download a "critical" update for Excel, however, it failed.  When I try and open an excel doc I am not able to ~ can anyone help???

    Hello - I attempted to download a "critical" update for Excel, however, it failed.  I shut down the computer.  Now I am not able to access docs in excel either ones I have already created or create new ones.  I continue to get an error message.  Please help!!!!!  thanks!!

    I suspect you may want to try Microsoft's Mac Office support forums, since this appears to be an issue with their software. 
    What error message (if any) do you get if you try and start up Excel?
    However, if it happened to me I'd probably remove Office and then resintall it from the original disks.  That will take you back to the original shipping version of Office after which it should update you to the latest version.
    Most likely when Microsoft's update software failed it managed to corrupt the Excel program files in such a way that they are no longer usable.  So a resintallation of the program is likely the only real option to fix this one.

  • I downloaded firefox and everything went well but I am not able to open.

  • When we delete a pdf from a file, the deleted file remains in the file for a while but we are not able to open preview or open the file. We recently upgraded to XI Pro. Is this common?

    Has anyone else experienced this?

    Hi Internetwerx,
    I'm not sure that I follow. Are you removing  PDF from a Portfolio, and it remains in the Portfolio briefly after deletion?
    What operating system and version are you on? When you say that the file remains for a while, what makes it disappear? Does it disappear when you save the portfolio, or change preview modes?
    I look forward to hearing back from you so that we can get to the bottom of this one!
    Best,
    Sara

  • I purchased iCould recently, but all my songs don't show up.  I updated iTunes Match and turned it on, but they're not there.

    I purchased iCould recently, but all my songs don't show up.  I updated iTunes Match and turned it on, but they're not there.

    I still cannot see all the music; some I downloaded and some I purchased.  For example, I downloaded two CDs by The Band Perry; one is on iTunes and one isn't.  I purchased iTunes Match before I changed computers so I could transfer it all to my new machine without have to load CDs again.  I also purchased some songs that are no longer there.
    I looked at the article you referenced and have completed all the recommended steps.  I have authorized this computer and updated iTunes match.  Is there any way to recover the music I downloaded, as well as purchases I made? (I purchased Viva la Vida by Coldplay and it's not on my iTunes.  There may be others, but I haven't noticed any others specifically.)
    Very frustrated....any help is appreciated

  • Its not at all startning and not giving any kind of error msg, and i restared pc many times and uninstall and installed many times, but still its not opening

    .its not at all startning and not giving any kind of error msg, and i restared pc many times and uninstall and installed many times, but still its not opening

    Also, if you downloaded earlier in the week, make sure you have the 37.0.1 updated that was released on Friday (I think).
    If needed, I suggest installing a slightly different way the next time:
    '''Clean Reinstall'''
    We use this name, but it's not about removing your settings, it's about making sure the program files are clean. As described below, this process does not disturb your existing settings. Do NOT uninstall Firefox, that's not needed.
    (1) Download a fresh installer for Firefox 37.0.1 from https://www.mozilla.org/firefox/all/ to a convenient location. (Scroll down to your preferred language.)
    (2) Exit out of Firefox (if applicable).
    (3) Rename the program folder
    ''(64-bit Windows folder names)''
    C:\Program Files (x86)\Mozilla Firefox
    to
    C:\Program Files (x86)\OldFirefox
    ''(32-bit Windows folder names)''
    C:\Program Files\Mozilla Firefox
    to
    C:\Program Files\OldFirefox
    (4) Run the installer you downloaded in #1. It should automatically connect to your existing settings.
    Any difference?
    Note: Some plugins may exist only in that OldFirefox folder. If something essential is missing, look in these folders:
    * \OldFirefox\Plugins
    * \OldFirefox\browser\plugins

  • I just upgraded to FF 7 and now when I open Firefox none of my history or cookies have been saved. I have checked in options that Firefox will remember my history and all relevant settings but it is not doing it. Is there a problem with this on FF7?

    I just upgraded to FF7 & now when I open it none of my history or cookies are saved. I have checked in options that Firefox will remember my history and all relevant settings but it is not doing it. Is there a problem with FF7?

    Can you attach a screenshot?
    *http://en.wikipedia.org/wiki/Screenshot
    *https://support.mozilla.org/kb/how-do-i-create-screenshot-my-problem
    Use a compressed image type like PNG or JPG to save the screenshot.
    See also "Help About".
    *Tap the Alt key or press F10 to show the Menu bar.
    In current Firefox releases (29 and later) the orange Firefox menu button has been replaced by the three-bar Firefox Menu button at the far right end of the Navigation Toolbar and this button is always visible, whether you have the menu bar visible or hidden<br>A consequence of this location is that you no longer can hide the Navigation Toolbar
    *There is a star like button next to the search bar on the Navigation Toolbar to bookmark the current web page and a "Show your bookmarks" button next to it to open the Bookmarks in a drop down menu.<br>You can find "Show All Bookmarks" to open the Bookmarks Manager (Library) at the bottom of this drop-down list
    *If you bookmark a page then "Bookmark This Page" in the Bookmarks menu changes to "Edit This Bookmark"
    *You can make the title bar visible via the "Title Bar" button at the bottom left in the Customize palette window
    It is still possible to have the menu bar visible via the right-click context menu of a toolbar to have menus like the File menu with Print (Ctrl+P) and Print Preview and the Bookmarks menu available.

  • HT4108 I'm trying to connect my iPad to my tv so that I can mirror whatever is on my iPad. I want to stream movies online and watch on the tv. I have the digital av adapter and an hdmi cable but it's not working. Any tips ?

    I'm trying to connect my iPad to my tv so that I can mirror whatever is on my iPad. I want to stream movies online and watch on the tv. I have the digital av adapter and an hdmi cable but it's not working. Any tips ?

    If this is an iPad 1, it won't mirror, but it will still output video from the 30 Pin dock connector.
    If your new TV has a conventional VGA in and stereo inputs you can try this connector.
    http://store.apple.com/us/product/MC748ZM/A/apple-composite-av-cable?fnode=3a
    I used to stream video from both Netflix and YouTube and from my Mac using iTunes sharing through my iPad then with this connector plug into my iPad and TV.
    It won't be high resolution, but it will get you picture from iPad to TV.
    Good Luck.

  • I have downloaded, extracted and installed Elements 12 but it will not open nor can I find the Adobe file in the file where I installed it to..  When I've tried to download and install again

    I have downloaded, extracted and installed Elements 12 but it will not open nor can I find the Adobe file in the file where I installed it to..  When I've tried to download and install again it says that the "Object Already Exists."  It may exists, but it is not visible in the file or in my list of programs on the Startup Menu.

    cactisken
    You should not have to uninstall Premiere Elements 12/12.1 in order to install and run Premiere Elements 13 on the same computer unless your computer is overloaded and the computer resources are compromised. Just use one program at a time.
    Can you still use 12/12.1 on this same computer that will not let you use 13?
    What specific Window operating system are you using?
    Let us go through the usual drill...
    1. Does the problem exist with and without the antivirus and firewall(s) disabled?
    2. Are you using a pen and tablet device instead of a mouse?
    3. Did you install the program with antivirus and firewall(s) disabled?
    4. Disable the SLCache Folder found in Windows 7, 8, or 8.1 64 bit
    Local Disk C
    Program Files (x86)
    Common Files
    Adobe
    and in the Adobe Folder should be the SL Cache Folder that you delete or disable by renaming the Folder
    from SLCache to SLCacheOLD.
    5. Are you running the program as Administrator and is the latest version of QuickTime installed on the same
    computer as Premiere Elements 13?
    Let us start here and then decide what next.
    Thank you.
