Newbie Upoad PDF to blob can remove file.PDF

I want the user to download a PDF and import it into a BLOB.
The part works.
If the user downloads the PDF EVIL, I want them to be able to remove the FILEA. PDF.

They can remove the FILEA. PDF, if they're waiting for 4 or 5 minutes.
Delete the FileA.PDF is the part that does not work, if the user is in less
4 or 5 minutes.
The PDF file is about 60K.
Here is the code example:
=========================
< code >

SELECT mypdf
IN temp_blob
OF fcsImpactUpload
where renname = "FileB.PDF."
UPDATE;
IF dbms_lob.fileexists (src_file) = 1 THEN
DBMS_LOB. FileOpen (src_file, dbms_lob.file_readonly);
lgh_file: = dbms_lob.getlength (src_file);
DBMS_LOB. LoadFromFile (src_file, temp_blob, lgh_file);
FcsImpactUpload UPDATE
SET de_pdf = temp_blob
where renname = "FileB.PDF";
COMMIT;
END IF;
UTL_FILE. FGETATTR ('AIMSORAPDF', 'FileA.PDF', DOESEXIST, FLEN, BSIZE);
IF DOESEXIST THEN
UTL_FILE. FREMOVE ('AIMSORAPDF', 'FileA.PDF');
ON THE OTHER
EXIT; -The file does not exist
END IF;


< code >

You open the file...
You load the file...

... but you do not close the file?

  • How can I find dbx file so that I can remove it. I am unable to open Outlook Express

    How can I find dbx file so that I can remove it.  I'm unable to open outlook express

    Original title: dbx file

    You try to remove Folders.dbx?
     
     
    In Windows XP, the files of user OE (DBX and WAB) are by default marked as hidden. To view these files in Windows Explorer, you must enable Show hidden files and folders under start | Control Panel | Folder Options icon | Opinion, or in Windows Explorer. Tools | Folder options | View.
     
    The path to the message will be very similar to this:
     
    C:\Documents and Settings\Your User of utilisateur\Local Settings\Application Data\Identities\ {long string of letters & numbers} \Microsoft\Outlook Express
     
    With OE closed, find the Folders.dbx file and delete it.  Another will be created automatically when you open OE.
     
    Note these possible side effects:
     
    When you re - start OE, it will build a new index of all *.dbx files it can read and create a new Folders.dbx. However, understand that you will lose the mail directory structure and message rules will probably have to be edited.

  • I have that one saved backup system, is there a reason to keep additional files prior to the last backup of system? I can remove them systematically?

    I run the Windows Image backup to a hard drive external on a weekly schedule. The result shows on the hard drive as "WindowsImageBackup\(User name)-PC\Backup (date) (number)"-currently about 80 GB (binary).

    I reserve about 135 GB of available space for backups of the system, so I save only the last backup of the system.

    So far, I have no problem with that.

    However, the disk hard, there is another folder '(USER NAME)-PC' & under which is a folder "backup of files (date) (number)" for each time that the backup system runs.

    These files vary considerably in size - for example, 1 GB, 12 GB, 22 GB. They delete or replace automatically - just, they accumulate.

    What I want to know is ~.

    What is the purpose\importance of these additional files?

    Since I only have a single saved backup, is there a reason to keep additional files prior to the last backup of system? I can remove them systematically?

  • LR can remove a part of a file name by renaming?

    I have a file name of 12012014 - 1234.cr2.  If I rename it to LR, it is quite easy to make testname-12012014 - 1234.cr2.  But I can remove 12012014 date [originally added by LR], so that the name becomes testname - 1234.cr2? It is probably a process in two steps, at least, and if it can still be done, for example, by using a wildcard character?

    For a SINGLE file in the metadata Panel of the library.

    Click in the file name box and type the name to what you want.

    For a batch of a folder of several files renaming selected (assuming that '-1234' is the file name suffix original camera.-)

    Select the files, press F2, select "Custom name - Original File Number '.

    Enter your name personalized (eg. TestName) in the custom text box.

    Then "12012014 - 1234.cr2" would be renamed "testname - 1234.cr2.

    PML instructions are precise and concise.

    My instructions for this issue are similar but more verbose - perhaps they will help you get your system fixed to the top (just read them first, then apply them).

    A "Cannot find...". ', ' Failed to start..., "Could not load..." ». "Might not work... "" Cannot run ""error loading... ". "or"specific module could not be found"message at startup is usually related to the malware that has been configured to run at startup, but the referenced file has been removed after a malware scan, leaving behind him a startup item or the registry entry pointing to a file that does not exist.
    It might be a removal of malicious software or an application not installed.  The entry may have a curious looking name since it was probably generated at random when the malware was installed. If you search your system for the referenced file, you may not find.
    Windows attempts to load this file but cannot locate because the file has been deleted for most probably during an analysis of the malware. However, an orphaned associate of remainders of startup parameter or registry entry and tells Windows to load the file when you start or connection.
    So you should delete the referenced entry Windows stop trying to load or run the file. It may or may not be included in the registry, but you can find it.  Autoruns (see below) you get the elements no matter where it is.

    If you are comfortable editing the registry, you can find and remove the reference directly from there or remove it using a popular third-party tool called Autoruns.  The problem can always be found in the registry well.

    Before making any changes to your registry by hand or with third-party tools, don't forget to first make a backup of the registry. There is no cancellation or exit without saving the option in regedit.
    Here is a link to a popular registry backup tool:
    You can also use the Autoruns to find the element of start remains little matter where he's hiding.

    Autoruns does not install anything on your computer.  It will display all startup locations where the reference may be then you can turn it off or remove it completely.  Here is the download link for Autoruns:
    Run Autoruns.exe and wait that he at the end of the filling of the list of entries.
    When the Autoruns is finished scanning your system, it will say "Ready" in the lower left corner.  Autoruns can be a little intimidating to first if you have never seen it before because it displays a lot of information.  You are really interested only a few sections.
    The problem is usually to start the system or the user startup entries, then click the connection tab and see if the startup item is there.
    Scroll through the list and look for a boot entry associated files in the error message.
    If you can't find on the connection tab, look in any tab.
    You can also click file, search to search for logon, or any tab for all or part of the name of the element.
    Right-click on the offending entry and choose Remove.  If you are not sure what it is, you can simply disable, restart and if the problem is resolved and then remove the offending entry.  If you don't see it in Autoruns, you may edit the registry and remove the item from your startup folder it.  Autoruns shall display the same information however.
    Given that you had or have an infection, followed with this:
    Perform scans for malware, and then fix any problems:
    Download, install, update and do a full scan with these free malware detection programs:
    Malwarebytes (MMFA): http://malwarebytes.org/
    SUPERAntiSpyware: (SAS): http://www.superantispyware.com/
    They can be uninstalled later if you wish.
    Restart your computer and solve the outstanding issues.
  • safely remove files to create space

    How can I safely delete files and programs to free up space on my hard drive? I have Windows XP, service pack 3. I have deleted many files, but still continue to not get «enough space to download...» Please delete space. "I don't want to delete everything that is needed to run my pc... I am computer illiterate.

    If you need space - it's probably the files * you * created who eat upward of space.  Go through your music, Documents, videos, photos, spreadsheets, your databases, emails, downloads and so on--MOVE those external storage.  Windows XP with SP3 and an assortment of installed applications must resume between 4.5 and 9 GB of total space.  Most "modern" computers have hard drives exceeding the 40 GB - usually more than 80-200 GB.  That means that you should have a little free other than * your * files.

    If you run low space - it's because you're not archiving/backup/or because your hard disk is not enough for your needs.

    You can disable hibernation if it is enabled and you do not...

    When you Hibernate your computer, Windows saves the content of the system
    memory for the hiberfil.sys file. As a result, the size of the hiberfil.sys
    file will always be equal to the amount of physical memory in your system. If you
    do not use the Hibernate feature and want to reclaim the space that Windows
    uses the hiberfil.sys file, perform the following steps:

    -Start the Control Panel Power Options applet (go to start, settings,
    Control Panel, then click on Power Options).
    -Select the Hibernate tab, clear the checkbox 'Activate the hibernation', then
    Click OK; Although you might think otherwise, selecting never under the
    "Hibernate" option on the power management tab does not delete the
    file Hiberfil.sys.
    -Windows will remove the "Hibernate" option of the power management
    tab and delete the hiberfil.sys file.

    You can control the amount of space your system restore can use...

    1. Click Start, right click my computer and then click Properties.
    2. click on the System Restore tab.
    3. Select one of your readers (or C: If you only) and click on
    the button "settings".
    4 change the percentage of disk space you want to allow...  I suggest you switch
    the cursor until you have about 1 GB (1024 MB or close to that...)
    5. click on OK. Then click OK again.

    You can control the amount of space used may or may not temporary Internet files...

    Empty the temporary Internet files and reduce the size, it stores a
    size between 64 MB and 128 MB...

    -Open a copy of Microsoft Internet Explorer.
    -Select TOOLS-> Internet Options.
    -On the general tab in the 'Temporary Internet files' section, carry out the
    Next:
    -Click on 'Delete the Cookies' (click OK)
    -Click on "Settings" and change the "amount of disk space to use:" to
    something between 64 MB and 128 MB. (It may be much more right
    now.)
    -Click OK.
    -Click on 'Delete files', then select 'delete all offline content '.


    (the box), and then click OK. (If you had a LOT, this may take 2-10
    minutes or more.)
    -Once it's done, click OK, close Internet Explorer, open Internet
    Solution Explorer.

    You can use an application that scans your system for the log files and
    Temporary files and allows to get rid of those:
