Hua,
I don't know how to tell you, but nobody (at least not me) is able to help you if you can't describe what you want to do in a context we all know and understand.
From your posts we don't get any context .
It's like you are telling us that you have an error.
Nothing else.
No information what the error is.
No information about how you get to the error (which steps did you do in the app to get the error).
Not even the subject seems to match your question.
From the pieces of info you scattered in your post I get that you have a table showing images which is working.
Why prev and next buttons? Tables are scrolled, there are no buttons involved.

  • I backed up files onto an external hard rive form my old PC. Now I want to retrieve the files to put on my mac but it is telling me to format it to Mac. How can I do this without erasing all of the data on my hard drive?

    Your drive was used with a PC and formatted NTFS which is proprietary Microsoft format.
    You need to install a third party program that will read the NTFS format.
    There is various software from PARAGON, Tuxera and NTFS-3G
    When you get the data off and have verified it to be good, reformat the drive either HFS+ for Mac use only, or for Mac and PC use then MSDOS (FAT32) for under 4GB files (best) or exFAT (for larger than 4GB files) is proprietary and Microsoft is appling for a patent, which would likely mean OS X won't be allowed to read it anymore without a licensing fee and you'l have to pay another third party software company to read the format, just like NTFS is.
    The less you have to rely upon third party sources to read your drives the better, this way if you have a issue and need to read the drive on another machine you don't need the software, and a internet connection and a credit card and...and...and...

  • My music files etc were all located on my old laptop which was stolen. I have just plugged my iphone in to my new computer and it has deleted all my files. Has anybody got any ideas on how to retrieve the files?

    WINDOWS?
    Connect the iPod to your PC. If iTunes starts syncing (ie erasing) your music automatically, hit the X in the upper right hand corner of iTunes display, to the left of the search box, to stop it.
    In Control Panel, Portable Media Devices, double-click your iPod.
    In the Tools menu -> Options, in the View Tab, check "Show hidden files and folders."
    Navigate to the Music folder. On my 'pod, the full path is
    Portable Media Devices\NAME of IPOD (F:)\iPod_Control\Music
    Select all the music folders, and drag and drop them into a folder on your hard drive, or directly into iTunes.
    And you're done! The iPod music folder structure is strange and inexplicable, but once you move your files into iTunes you can set it to automatically organize your folder by artist and album to clean that up. (To do this, in iTunes Edit menu, choose Preferences and in the Advanced tab, check "Keep iTunes Music Folder organized."

  • My daughter created a movie using iMovie, which she has worked on for a month, when trying to save it on a jump drive she was asked to "finalize" the movie...now there is no record of it at all. Any ideas how I could try and retrieve the file?

    My daughter created a movie using iMovie 11, which she has worked on for a month. When trying to save it on a jump drive she was asked to "finalize" the movie, and while this was running (quoted 13 hours!) she received an error message. Now there is no record of it at all, I have looked in trash etc. Any ideas how I could try and retrieve the file?

    The file cannot be reloaded in iMovie using File > Open Recent  ??
    There is no trace of the file in a Spotlight search?
    The project files are not under <user>/Movies/iMovie Projects ??
    Finalizing creates small, medium and large version of the finished video. It does take a long time, but it should not destroy your project files.
    Oh, and you really MUST have a backup of your files. You can expect to lose files if you have no other copies of them.

    Hello there,
    It sounds like you have a video file you exported from iMovie that you would like to import back into the program. Depending on the version of iMovie the process is a bit different so choose the correct article for your version:
    iMovie '11: Import video from movie files
    http://support.apple.com/kb/ph2153
    Or
    iMovie (2013): Import media on your computer

  • Mac Book Pro 13" LPTP-Photo Booth Recorded Video File won't find my video/movie that I recently recorded from Sun 9-1-13. Is there a way I can retrieve the files under the Time Machine or will I need to download something for iPhoto Booth?

    I have been having the most difficult times with the use of iPhoto Booth for recording movie files of church services. It seems if I make a rename on the files, for some odd reason, I cannot find it in any of my Files Folders in Finder. I need to know is there a more simple way to retrieve movie files thru iPhoto Booth or is there something I may can download to fix this issue? Also, is there a way the videos can be flipped around to not a mirror image, but to a reverse camera? Please anyone who recognizes this problem, contact me ASAP. Thank you for your support!

    You used the data.  Verizon can not see what it was sued for.  However your phone can see whats apps used the data.  go to settings-data usage- there will be a place that says data usage cycle.  line the dates up with your cycle.  then there will be a bar graph below that   extend bother white bars one all the way to the left and one all the way to the right.  after those are extended below that will be a list of apps,  there should be one that used over 2 gb and that will show you what app used that data in her purse

  • I use audio memos and files are saved in icloud. while updating audio memo the apps stop working. i cannot access the apps. how can i retrieve the files saved in icloud ?

    I can't access the audio memo apps but i can see under usage - manage storage that all the files are located in icloud. how to extract .wav files from icloud if the apps is no longer responding to fileshare in itunes? Thanks.

    yes it was solved some time ago. i cant remember exactly but i think i disconnected from the internet and tried accessing the audio apps (or maybe i had accessed the apps first then only turned off internet i cant remember) thereafter the files were in my local apps and then I turned off use icloud. i suggest you backup your ipad on itunes before trying anything. All the best - hope you solve your problem.

  • Retrieving the files from inbound directory using RZL_READ_DIR

    Hi,
      I am using the function module RZL_READ_DIR to pick the files from AL11 (application server)  some times it is picking all files and in foreground also it is picking the all files from AL11,  but in background sometimes it is not picking the files but when i check in foreground all the files are showing , after 2 or 3 days the function module is picking those files also from background .
    please suggest what would be the reason for not picking in background?
    Any help please.

    Note that the domain for your input parameter is of type text200.  TEXT* domains in SAP support upper/lower.  Supply the value to the FM in the needed case (by inserting the value into a declared variable of type text200) and the FM will work.

  • Client_text_io does not write the file but does create it.

    Hello there!
    I have a form which generates a .txt file using client_text_io webutil function.
    this is the procedure:
    PROCEDURE CREA_FILE IS
    MYFILE CLIENT_TEXT_IO.FILE_TYPE;
    OUTFILE CLIENT_TEXT_IO.FILE_TYPE;
    MFILE VARCHAR2(1000);
    MLINE VARCHAR2(5000);
    RESP NUMBER;
    BEGIN
    MLINE:='LINE TO WRITE...';
    MFILE := C:\test.txt;
    OUTFILE := CLIENT_TEXT_IO.FOPEN(MFILE,'w');
    CLIENT_TEXT_IO.put_line(OUTFILE, MLINE || ' 123');
    CLIENT_TEXT_IO.Fclose(OUTFILE);
    EXCEPTION
         WHEN OTHERS THEN
         CLIENT_TEXT_IO.Fclose(MYFILE);
         message('ERROR: '||SQLERRM);
    END;
    It works on OAS 10g + forms 10g. the file is created fine, BUT I have tried with forms 11g unsuccessful.
    My forms 11g are running under weblogic and the RedHat server.
    Im running the forms app from my laptop Windows XP.
    I configured webutil as the MOS note said, the thing is, the file is created, but no data is writted.
    I can open the file test.txt but the line I tried to print is not there, the same thing with 10g and the file is good.
    help me please.

    What are you doing after writing to the file? Are you leaving the form? Forms performs event bundling when sending data over to java beans;
    v_FILE_HANDLE := CLIENT_TEXT_IO.FOPEN (FPATH, 'W'); most certainly uses get_custom_property at the end to retrieve the file handle from the bean which will cause a "synchronize" as data must be retrieved from the bean before continuing in the PL/SQL code whereas
    CLIENT_TEXT_IO.Put_line(v_FILE_HANDLE,v_string_prov);
    CLIENT_TEXT_IO.FCLOSE (v_FILE_HANDLE); most certainly uses set_custom_property which is a one-way street and data is bundled up and sent as one package. If you have e.g. a exit_form right after those calls there is a chance that forms waits for some other data to be sent over to the bean but won't send it, as the form doesn't exist anymore after the exit_form. The same would happen if you'd do a
    v_FILE_HANDLE := CLIENT_TEXT_IO.FOPEN (FPATH, 'R');
    CLIENT_TEXT_IO.FCLOSE (v_FILE_HANDLE); right after writing your form as fopen will cause the sync (with the possibility that java will still hold a file lock on the file as the fclose method won't be called).
    cheers

  • Kernel panic/invalid node structure; please help retrieving my files!!

    Hi everyone, thank you for your time in advance... if anyone has ideas about how to solve it, I appreciate this very much!
    OK, here is how it began: while I was working on the airplane using PowerPoint, the gray spinning wheel appeared after which PowerPoint stopped working. I pressed the power button to exit (all applications froze). (So much for trying to get more work done...)
    Next, I powered up the computer but it would not boot up, with only gray spinning wheel showing.
    Next, tried to boot up while pressing power button and holding shift key. After some time (10 minutes), an error message appears. Researching it on discussion forums, I found that it is called “kernel panic”. Here is beginning of the message:
    panic(cpu 1 caller 0x47f5ad): "Process 1 exec of /sbin/launchd failed, errno 8\n"@SourceCache/xnu/xnu-1504.15.3/bsd/kern/kern_exec.c:3145
    Debugger called: <panic>
    [additional information here]
    Also, message “You need to restart your computer. Hold down the Power button until it turns off, then press the Power button again” is shown transparently in the middle of the screen over the “panic” message output.
    I turned on and off the Power button many times, but I get the same error message.
    I also tried Apple Hardware Test but it did not work (it did not generate any messages).
    Next, I tried to use the Disk Utility using the Installation Disk that came with the computer. After I clicked “Disk Repair”, here is the log:
    Verify and Repair volume “Macintosh HD”
    Checking Journaled HFS Plus volume.
    Checking extents overflow file.
    Checking catalog file.

    Error: Disk Utility can’t repair this disk…disk, and restore your back-up files.
    At the end, a window presented over the error log stated :
    “Disk Utility stopped repairing “Macintosh HD”
    Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your back-up files.
    I need to retrieve my recent files!! Please Help!! Argh!! I promise that I will promptly back up my files now! I did not use Time Machine, and only some of my files are backed up.
    From what I read on the discussion forum, I will probably need to erase the disk and then do a fresh installation, but could someone please guide me with regard to how to back up the data / retrieve the files? I may have access to another mac so I’m thinking that the FireWire Target Disk Mode may work. I also have spare external harddrive (formatted for mac) (not partitioned). Also, how do I retrieve the files from the other computer if the FireWire transfer works?
    Also, the second step is to do a new installation, but is there any reason why “Archive and Install” using Disk Utility won’t help? I have some additional programs installed (Illustrator, Photoshop) so this means if I do a new installation, I will need to re-install those as well?
    I did some investigation, and it looks like this problem is similar to this:
    https://discussions.apple.com/message/18098343#18098343
    But my main issue now is to retrieve the files!
    Also, how do I investigate whether this problem is due to a failing hard drive or a natural file system corruption ? (so should I get a new harddrive or do a new install).

    I don’t know what is the OS version;  it is Snow Leopard OS X ……. I bought it in September 2009.

  • I have a Pages file that I created on my iPad that I used iCloud to store. There are no backups anywhere of this file. The file is stuck on updating on iCloud and on the iPad the file is inaccessible. There is a black bar over it which greys the file out.

    I have a Pages file that I used my iPad to create. iCloud backed this file up to its server. The problem is that my iPad somehow locked itself. I had to restore it, the file was lost on the iPad, and when I went back to iCloud to retrieve the file it said it was Updating. The file is showing on my iPad, but it is greyed out with a black bar across the bottom of it. I have been working on this file for months, and I am not about to lose it! Please can someone tell me how I can get my file to download at least to my iMac.
    This file has worked perfectly in the past, and what I didn't realise when the iPad was locked down was that the Airplane Mode was on, to save battery. If that had been on it would have synced it again.
    Can anyone help me? I'm supposed to be sending this file (completed) off to a company in three days.
    Thanks

    On the iPad tap Settings > iCloud
    Toggle Documents & Data off then back on then restart your iPad.
    Hold the On/Off Sleep/Wake button down until the red slider appears. Slide your finger across the slider to turn off iPhone. To turn iPhone back on, press and hold the On/Off Sleep/Wake button until the Apple logo appears.
    On the iMac open System Preferences > iCloud
    Deselect the box next to Documents & Data then reselect it then restart your iMac.
