• ORA-31000 lifting even when USER_XML_SCHEMAS does not have any line.

  We create a huge XML file with patient information and medication. Read us the values of table tag and create the XML file and insert a CLOB column in a table.

  Before inserting, we want to make sure that the XML is validated against an XSD.

  To test this I created a small SP.

• Need to reinstall windows, but does not have any CD - Satellite Pro L20

  Hi, I wanted to reinstall Windows XP home on my Satellite Pro L20, but do not have the software that my laptop came with (read the discs lost). I have a valid XP tone (like its stuck on the bottom of my laptop), but no disc so I tired using a copy of a cd of Windows XP home, which did not work, but let me go as far as the formatting of the hard drive.

  So now I use Ubuntu, but want to reinstall Windows. Have valid product key, but no software to reinstall.

  Any suggestions?

  Thank you

  Christopher

  Valid key will not help you. This key belongs to the image recovery and copy included WXP he.
  If you have two options. Either you order original Toshiba recovery image or use Microsoft installations CD key which belongs to this copy. All the necessary drivers, tools and utilities that you can download at Toshiba support page under http://eu.computers.toshiba-europe.com > support & downloads.

  Good luck!

• I have no sound on my computer, it does not have any pregnant either.

  My computer no sound and does not recognize the speakers won't play CD

  I had the problem with the speakers being not recognised by Windows 7 and the solution that worked for me was to go to start: System: Device Manager: sound, video and game controllers: from there, right-click on your High Definition Audio (or whatever your audio) and select update.  Worked immediately for me and not too early to watch videos with my son before bedtime :)

• XP host does not have any file that begins with "VM".

  Problem of crazy that I can't understand.  Under XP Pro SP3 on a desktop computer and try to install VMPlayer 3.01.  If I try to run the file that I downloaded I get a warning that "this application has failed to start because the application configuration is incomplete.  Reinstalling the application may fix this problem. "This exact file installs without problem on my XP Pro laptop.

  Here are the best, if I rename the file, so it does NOT begin with "VM", it will install.  But then if I try to turn on a guest operating system, I get an error because the other files that start with "VM" are started and fail.  If I rename notepad.exe to vmnotepad.exe it will not work!

  I uninstalled VMplayer and tried again with the same results.  I even tried a few VMware cleaner utility but no change.

  Any ideas?  Thank you.

  I fear that the evil is already due to 5 questions.

  Maybe the well known software little CCleaner, http://www.ccleaner.com , can be your best friend for help:

  Cleaning the registry.

• Could not load the add-on Firefox 6 Manager. Does not have any modules or plugins. Stuck on 'Loading '.

  I am currently getting some "funky" my Firefox responses, so I wanted to check my addons to see if one of them was the cause.
  But I can't get the Add-ons Manager to load, it gets stuck on the page 'Start' - displays just the circle and "Loading" animation next to him.
  Have you tried to restart FF, restart the PC, start without addons.
  Because I do not run many addons or plugins, this isn't a major case-, but if someone could help me I would be grateful.

  When you open the tab of the Add-ons Manager, click anything other than to get modules.

  This item charge information on the site of modules, which I think is running slow, probably because of all the Tuesday update update related applications, both Firefox 6 and Firefox 3.6.20. Now seems to be much worse than what I saw with 4.0 and 5.0, so it is perhaps not as simple as that. But whatever the cause, once you get off that get tab Addons, the AOM window should then open with what you have selected in the future - at least that's how it works for me.

• Acer does not have any spare part for the B326HK monitor.

  I bought on 11.06.2014 in the monitor of Belgium a B326HK 4 K and it was after 2 days already broken. The monitor has been sent to the Acer service center, but it seems that they have no spare parts. I've had better service expected of Acer. Their explanation is that it is a fairly new monitor and they can get difficult spare parts. Are there people who are facing this problem?

  @ Cory. Today I finally received news of Acer with the message that the motherboard of the monitor showed an error. Because apparently these motherboards are currently difficult to obtain, Acer will send me a new monitor. When I read here on the forum about problems that have other owners of this Acer B326HK, I think they could actually sit with the same faulty motherboard in their monitor.

• Invisible signatures by the incremental update does not have any signs?

  Hi all!

  Sorry if here is not the right place for my question. If this is the case, is - can someone inform in the right place?

  Well, I am trying to build a tool to sign a PDF of incremental update using Delphi [].

  I am beginner in PDF structure and the brevity of the time made me perhaps a bit inattentive and desperate.

  After 2 months of hard fighting, I managed to get Acrobat Reader know my PDF (initially created by a java tool called SignServer) has a signature and recognize the certificate but it says that the certification is not valid because 'the byte range is invalid.

  I analyzed the PDF file in a hex editor and the byte range signature so any other object compensates seems correct.

  My PDF test is here: https://drive.Google.com/open?ID=0B0KKmaB-a0Z4SDZfNXdZRWZEem8

  Can you tell me what the problem with this PDF?

  Many thanks for any help!

• I can't create an installer, after install the Vision Builder demo and then uninstall it. I can't create a Labview Installer more, he asks me an installer of generator of Vision, even if Labview my program does not have nothing to do with it...

  I can't create an installer on LabView, after install the Vision Builder demo and then uninstall it. I can't create a Labview Installer more, he asks me an installer of generator of Vision, even if Labview my program does not have nothing to do with it...

  Hi, Shada, this can happen if you include additional installers to your installer for example DAQmx. When you do this the installation program must include other files like MAX (Measuremente and Automation Explorer). Probably when you installed Vision Builder he updated MAX, so when your Installer try to understand MAX, his request the source where it was installed in your computer in this case Vision Builder.

  Here you can cache information so it is not asked once again, or you can download a version more recent fo DAQmx, then it will update MAX and change the dependecy.

  You can find more details about it in this KB:

• Satellite A350-13 a - function keys does not work

  I have the Satellite A350-13. I installed Windows 7 for 2 weeks.

  The function keys does not work although I have installed the Toshiba value added package, which is responsible for the activation of the function keys.

  What the solution to this problem?

  > Function keys does not work although I have installed the toshiba value added package, which is responsible for the activation of the function keys

  Next to the VAP (value added package) you need to install the Flash Utility card support!
  Card Flash utility support controls the keys FN and not the VAP! But VAP is also needed.

  Good bye
