Reading from an Excel Doc and Writing to a new Excel using jackarta's POI

Hi, could anyone know how to read a line from an existing Excel document and writing it to a new Excel document?
Please reply soon.
Thanks.

Flex, when run in the Flash Player in a browser, cannot
access ANY client resources, including the file system.
In your example, recipes.xml is loaded into your app at
compile time, from the server.
In order to write that file back to the server, you must have
some server-side functionality. This functionality can be
implemented in JSP, ASP, CF, PHP, Java, etc.
Here is an example, that loads an xml file from the server,
edits it, and saves it back. The example shows both JSP and ASP.Net
back-end code. Note: the xml editor part makes if much more complex
than is needed just to load/and save a file. You will be able to
pull that portion our of the rest if you want.

  • Windows 8.1 PC, using reader, when searching a folder containing approx 100 doc's. If i search for a word, no results are returned. only the doc names can be found but nothing from within the doc. This is a new problem and was not the case before.

    Works perfectly fine for me with the latest Reader version (11.0.09).
    You write that it worked "before"; before what?  An update?  Update from what version to what version?

  • "Lightroom encountered and error when reading from its preview cache and needs to quit"

    I keep receiving this error every time I open LR, "Lightroom encountered and error when reading from its preview cache and needs to quit" and the app won't open. It said LR would try and fix this error next time I opened it but the error remains. I tried uninstalled and installing the app and the error remains.
    Any Ideas here? Is there another app that may be telling it where to look for the cache and it no longer there? I was using a ramdisk for a bit but ditched it. Not sure if that has something to do with it but it seems suspect.
    Your thoughts?

    Talked to Adobe support this morning, this is their response in case anyone else is looking for help. I'm running a Windows 7 box, LR 5.6.
      Gokul: Click on start and type %appdata%, then open roaming folder.
      Edward: ok
      Gokul: Open Adobe folder.
      Gokul: Open Lightroom folder.
      Gokul: Open Lightroom folder> Preferences.
      Edward: ok
      Gokul: Rename Lightroom 5 Preferences.agprefs file as Lightroom 5 Preferences.agprefsOLD.
      Edward: OK
      Gokul: Please check if you can launch Lightroom without any error.
      Edward: it shows me a welcome screen and is asking me to select my country
      Edward: aka, register the software
      Gokul: You can skip and launch it.
      Edward: LR catalog not found
      Gokul: Please select the catalog.
      Edward: my original catalog?
      Gokul: Yes.
      Edward: testing integrity of catalog
      Edward: loaded just fine
      Gokul: Okay.
      Gokul: Please check if you can re-launch it again.
      Edward: yes, it worked!
      Gokul: Excellent!
      Gokul: Since your preferences were corrupted you were facing issue so we renamed the preferences file to reset it.
      Edward: aha....ok
    All of my import/export presets were intact along with develop user presets. I'm happy as a clam for my $10/month!

  • Help! Want to read from a xl file and get an output voltage value!!!

    Hello..
    I`m a beginner, so please help..
    My program should output an voltage value that is read from an xl-file with one collum. The most important is that each values in the xl graph should be read per iteration. So that the file is read over time. I want to use this xl file to controll the output signal over time.
    Can anyone show me how this VI would look like, and what would the xl file look like??

    The easiest way to do this is to save your Excel file as a comma or tab separated text file and not the native Excel format. Then you can use Read From Spreadsheet File (on the File I/O palette). Using this, you can read the file all at once and then just have a 1D array that you can wire to a while or for loop so that with each iteration of the loop, you get one element in the array. A for loop automatically indexes an input array. Reading the file all at once will be more effecient that reading the file line by line.

  • Reading from an excel file

    I was wondering, what do i need to look at to get cracking with making a programme that can read from a excel file
    I was thinking of making a programme that uses a excel spreadsheet <this spreadsheet is made and provided by the national lottery and has all the winning combinations that have been drawn in past draws> and reading them in and generating a list of combinations that have not occured yet
    Its just for a bit of fun, but could be a good challenege
    thanks

    If all you want to do is select from the excel sheet you may find it easier to use the jdbc option, I have an example of some code I wrote that does a select from an excel sheet and it may be useful for you:Just my opinion here but I would avoid using odbc to deal with the spreadsheet if at all possible.
    Time for a war story:
    After losing an argument with some business, marketng and management I had to develop a program that accepted spreadsheets as datafiles and it was nothing but trouble.
    I experienced all kinds of type problems, the most common and annoying of them being
    that the driver (via some logic unknown to me) will determine the type of each column.
    Any data that is does not match that expectation is dropped (I found that the query returned NULL).
    As far as I could tell there was no way to make the driver treat the data the way you want it too.
    After much trouble and lots of manual intervention by the poor person who has to deal with this data on a regular basis it seems to be working but it was not fun it is still very ugly code.
    You may not end up reliving my tale of woe, but I though I would give you some fair warning.
    As I continue to say "Spreadsheets are not a reasonable data transfer format."

  • Lightroom encountered and error when reading from it preview cache and needs to quit

    A power outage caused my Lightroom 5.2 to shut down without closing.  When I powered back up and opened lightroom it gives me an error "Lightroom encountered and error when reading from it preview cache and needs to quit" and then it says it will try to fix it the next time it opens. I have opened it 20 times and it is not fixing it. I removed the program completely and upgraded to 5.5 AND it is still giving me the same error.  Is my catalog corrupt or something? I had it set to automatically load the most currently used catalog, so it is not allowing me to open or start a new catalog either. HELP!!!

    Search the forum, this has been answered many times.

  • LR encountered an error when reading from its preview cache and needs to quit.

    I have the 30 day trial version of Lightroom.  I was able to use it for one week, but the past 1.5-2 weeks, it has been locked up and giving this error message.  How do I resolve the problem?  And how do I reset the 30 day free trial?  I would like to have time using the product, before deciding on the annual contract.
    "LR encountered an error when reading from its preview cache and needs to quit.  Lightroom will attempt to fix this problem the next time it launches."
    Thank you.

    Delete the preview cache from the Lightroom folder in your Pictures folder if you used the default placement. It has the extension .lrdata.
    You cannot reset the trial period.

It said LR would try and fix this error next time I opened it but the error remains. I tried uninstalled and installing the app and the error remains. I have windows 8. Can anyone please help???

    Use Windows Explorer to open the folder containing your catalog. The normal location is Pictures\Lightroom. Locate a folder with the extension .lrdata and delete that folder. Then you should be able to start Lightroom again, and Lightroom will begin building and new previews folder. Do not delete anything else.

    I've tried renaming my catalog.lrcat file.  I've copied over my most recent backup of the catalog.lrcat and that didn't work either.

    On Mac:
    PS - to open the previews "folder" (a "package" is just a "special" folder) on Mac, ctrl-click and choose "Show package contents.." - same way you open any other special folder, like .app or .lrplugin..

    Delete the preview cache using your operating system. It is a folder whose name ends with Previews.LRDATA. Do not delete the Lightroom catalog, which ends with .LRCAT

    You need to delete your preview cache and have Lightroom rebuild it.   Cache location can be found here.
