Hello

Better just to have a simple statement in the else block

ELSE
open my_ptr for
SELECT NULL
FROM DUAL;
return my_ptr;

So whenever the IF fails, your other work without value in the cursor.

In fact, this slider returns a single row that contains a NULL value.
Better add a condition that will always evaluate to false (0 = 1).

  • I get this error message 'The URL is not valid and cannot be loaded' when I try to go to Firefox home. I uninstalled the modules, uninstaleed and reinstalled a new fresh firefox which did not help

    I get the following error message 'The URL is not valid and cannot be loaded' when I try to go to firefox home. I uninstalled modules, uninstalled Firefox and then install a new version. Still have the problem.
    Thanks for the help

    This problem may be caused by a corrupt installation of Visual C++ or incomplete (several versions can be installed-by-side; SxS) it lacks certain runtime components (redistributable Packages), which depends on Firefox (problem with an embedded manifest file that specifies a specific runtime version).

    You need to install the missing components (for example, Redistrbutable end 2005 ++).

    Follow the suggestions below for a possible solution:

    Method 1:

    Step 1: Start in safe mode and check if the problem persists.

    Start your computer in safe mode

    http://Windows.Microsoft.com/en-us/Windows7/start-your-computer-in-safe-mode

    How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7

    http://support.Microsoft.com/kb/929135

     

    Note: After troubleshooting, be sure to configure the computer to start as usual as mentioned in step 7 provided in the above article.

    Method 2: I also suggest that you scan your computer with the Microsoft Security Scanner, which would help us to get rid of viruses, spyware and other malicious software.

    The Microsoft Security Scanner is a downloadable security tool for free which allows analysis at the application and helps remove viruses, spyware and other malware. It works with your current antivirus software.

    http://www.Microsoft.com/security/scanner/en-us/default.aspx

     

    Note: The Microsoft Safety Scanner ends 10 days after being downloaded. To restart a scan with the latest definitions of anti-malware, download and run the Microsoft Safety Scanner again.

    Important: During the scan of the hard drive if bad sectors are found, the scanner tries to repair this sector, all available on which data may be lost.

    Let us know if that helps.

  • I get this error in the book error log:

    "No master pages applied because the MasterPageMaps table contains no information mapping"

    I don't know what it is, or why it appears now. I've never messed with this feature before. The thing is that I can't get the first document in my book to generate properly as this message began to appear. In my first paper, I have a background image that spans the whole page. It is used as a "cover" for a PDF output. This image vanishes whenever I try to update my book and all formmating on the page is lost.
