Welcome to the Oracle Forums. Please take a few minutes to review the following:

Following these simple guidelines will ensure a positive experience in any forum; not just this one! ;-)
It has been my experience that when you use the built-in function Execute_Query the NO_DATA_FOUND exception is handled at the error - released level rather than the local exception handler. If you run a SQL statement in a trigger, then local exception handler will catch the exception - if you have a. Check your form/block-Error trigger level and add a handler for the ORA-01403 or FRM-40735 errors and display your message here.
Hope this helps,

HP pavilion dv9925nr sound does not work help please
Hi I have a hp pavilion dv9925nr laptop and I spent in Windows XP pro and now the sound does not work and iv tried everything iv downloaded all the drivers on the internet and everyone simply goes on to say: no driver no has been supported in this package and its driving me crazy please can someone help before I just use it to target paratactic
Hello:
Then I recommend that you follow the instructions in the guide to the link I posted above.
After you install the MS UAA driver, you may need to install the audio driver updated the posted on this link:
Conexant High Definition SmartAudio 221 drivers (ModelC700, Vx5xx series and dvx5xx and ABOVE )
Pilot modded by silver here
Unzip it to a folder... Use the device, right click "Audio Device on HD" Manager, choose Update driver,
Not to connect, install from a list or specific location,
Select don't search, I will choose the driver to install.
For the hardware Type select 'show all devices '.
Remove control "Show compatible hardware" and click on 'disk '.
Next... Navigate to the unzipped folder and choose the "WiSVHe5.inf".
Ignore XP when he complains, Reboot.If none of this works, try to reinstall XP and start from scratch. If you do not see your appliance an audio controller if you reinstall XP, then more than likely it is a hardware failure of the audio chip.

I need a driver/files mouhid.sys, my mouse support does not work. Please thank you!
Hmm, a strange thing to have disappeared. Do you have a virus or checked for malware scanner?
The mouhid.sys file is supposed to be in % systemroot%\system32\drivers. You pouvez find a copy of it in % systemroot%\dllcache. If it's not in... \drivers and is in... \dllcache, recopy the... \drivers. (You may need to do this in Mode safe.)
Except for the above bit of luck, there are several ways to recover.
1. use msconfig:
Get your installation CD or locate a copy online
Since an administrator account, run msconfig ( -R, msconfig)
When "msconfig" opens, select the "Général" tab and click on the button "expand file...". »
(This will open the window to "Develop a Source of Installation file")Enter 'mouhid.sys' in "file to restore:
Enter the path to the DRIVER. CAB file in the \i386 on your installation media directory.
(or browse to...)
Enter "c:\windows\system32\drivers" in the "save in:" entry.
Click "expand".
'mouhid.sys' is now where never told you develop to...2 use the utility auditor of system files (SFC) to check the missing files and restore them if necessary.
You will again need your installation media and, if you have installed the Service Packs, the CD-ROM for
the latest Service Pack, you have installed.From an administrator account, type: -R, sfc/scannow
SFC calls for, first of all, your installation media, and then later the service pack CD-ROM. If SFC wants to replace the files, leave. If the SFC rejects your Service Pack CD-ROM, read the KB900910 Microsoft Knowledge base article. Note that this article applies to SP2, but is also applicable to the SP3. Just use your common sense and use SP3 where the article refers to SP2.
If you don't have a CD-ROM Service Pack 3, or order it (U.S. / Canada , Europe, Africa , Asia or South America ) from Microsoft or download the ISO (here ) and burn it. Be sure to Select the appropriate language if you download ISO. Note, I recommend that you install Service Pack 3 on a CD-ROM, rather than through Windows Update so that youpouvez use SFC with success!
Please, vote if it is useful! Please, click on Mark as answer if that answers your question.

I have back Windows 10 to Windows 7 Home Premium as suggested previously and it worked fine. Then knit as well as the sound function keys, but I now have a problem with the printer. I have a Toshiba Satellite.
I am trying to print and get the message "...". You must install a printer.

This problem may occur if the print spooler service is not running.

my serial code does not work how can I make it work
my serial code does not work how can I make it work thank you
Hello
If you have a creative cloud subscription then you do not require a serial number to activate it, all you need to do is sign with your ID (Email used at purchase) Adobe in creative application Cloud to activate your membership. See,
Connect and disconnect activate Cloud Creative applications
Solve common problems of activation and deactivation of creative cloud.
Activation and deactivation of troubleshooting
Find solutions to activation errors that may occur during the launch of Adobe applications.
I checked with your Adobe Id on the forums that there is no active subscriptions to this topic.
If you have any other Adobe id try please activate the products with that.
