• How to remove line empty when the data are not for a text field

  I created a PDF with Acrobat Pro 11 model. This model has an address of the employer with the address line 1, address line 2, city, State, zip code, country. The requirement is to show address line 1 and line 2 address in separate lines and address line 2 cannot be present always. If address line 2 is not present then the PDF should not show a blank line. How do I get there?

  These data are populated through xml by a publisher of BI. New line characters do not work.

  Appreciate your help on this.

  Hi sprphoto123,

  If you do not enter data in the text field 2 then you can set the form field property to is not mandatory, but if you want to disable the 2nd text field, you can add a check box in front of it to turn off the field. This can be achieved using JavaScript.

  Kind regards

• Reader XI Customization Installation Wizard does not remove previous versions

  Downloaded the installer msi drive XI and XI Customization Wizard.

  Created installtion STD and setup.ini files, and specified to remove previous versions of the wizard.

  Recorded this and deployed to test machines via WSUS server and third party software, Local Publishser updated and included the mst and ini files update package in.

  XI player installed.

  Reacer 10.1.4 is not uninstalled.

  Checked again and uninstall all previous versions of the player is selected.  Documentation indicates that any version 6 upwards will be uninstalled, but it didn't happen.

  What else is needed for the old version to uninstall when XI is installed?

  TIA

  Rick

  Hi Rick,

  Try to close the Customization Wizard and he raises. Open the same drive package again.does the box remove previous drive appear checked? If Yes, then it should certainly delete the previous version of the player either 10.1.4

  If on the reopening of the whole, the Remove previous drive checkbox unchecked then check and save the package. Now when installing this package, previous drive is removed. I just checked myself!

• How to remove a Word from the default dictionary of firefox?

  How to remove a Word from the default dictionary of firefox?
  If I wanted to remove the word 'dog' or 'and' for example

  There may be a range of reasons for wanting to do this, including the deletion of the words you use rarely as similar to other common spellings used words for example. "minute" and "Minuet", delete the words that you find personally offensive, or removing words that, because of linguistic or cultural background, you would not consider words at all.

  Note that I'm not asking how to remove my 'dictionary' words, words that I added myself.

  Hello

  I talked to a few people and I think I'm able to help you with this.

  There are two dictionary files, the default that comes with your version of Firefox and personal 'custom' that you create yourself with phrases and words.

  If you want to change the personal;

  1. Copy Subject: support and paste into the address bar.
  2. Next to the profile folder, click the marked File Show
  3. Find the file persdict.dat. Rename a text file, open, modify, re save it as persdict.dat and replace.

  If you want to change the default dictionary, it could be more of a problem and a lot more technique to do. I would recommend that you look at the problem differently and consider filtering of pages based on inappropriate content using Add-ons such as ProCon Latte Content Filter.

  I hope this helps, but if not, please come back here and we can look at another solution for you.

• I found that if it becomes necessary to use time machine to return to an earlier existence to reinstall the iphoto library, if for some reason, you lose lose, then when you try to synchronize your ipad is not recognized by the computer.  As one

  I found that if it becomes necessary to use time machine to return to an earlier existence to reinstall the iphoto library, if for some reason, you lose lose, then when you try to synchronize your ipad is not recognized by the computer.  So when you try to synchronize the pictures, they are all removed from the ipad and trying to reinstall everything again.

  This may or may not work immediately.  In my case, only half the photos have been installed, and then the error message came that the rest of 9000 can be installed.

  I contacted Apple support team who has made various suggestions.  Subsequently clicking on a photo list in iTunes were all going again and pictures of 9000 then installed.  When I asked the support team what could happen I was told that it was a "glitch".  I don't like seeds they mean that there could be an error in coding somewhere.

  Here me again.  I use an iMac and iPad.  I don't know why XP and iPhone came.

• How to remove a contact from the drop-down list?

  How to remove a contact when, if forwarding a message, the icon flashes in space 'To' to enter the email address, when you press the first letter of a recipient, it displays a list of previous names/addresses used. This can add to a huge list! Most of the time, it is useful, but how can I shorten the list by removing unwanted contacts in the drop-down list? I got them removed from my address book/contacts (and they are deleted) but even after re-booting the computer, their names still appear in the drop-down list as before. All solutions?

  Instead of typing the first letter of the name of the recipient

  Press on the envelope icon to next to the box where you type the name of the recipient

• How to remove a shortcut with the command line?

  How to remove a shortcut with the command line?

  How to make a backup of the local users and groups with command line?

  You delete a shortcut, just as you would remove any other file.  A shortcut will end with the extension ".lnk".  So assuming you are trying to remove the shortcut named "Shortcut.lnk" which appears to the user 'Bob's Office, you use the button Delete (del) or 'clear' command by specifying the full path to the file.  (Remember to put filename in quotes if there is a space anywhere in the path or name) as in:

  del "C:\documents and settings\Bob\Desktop\Shortcut.lnk".

  What kind of a backup 'users and groups' you want to do?  If there is a backup of the users and groups as written in the registry, a good registry as C:\WINDOWS\ERUNT backup program that will make the command line.  If you are trying to backup all users and their data as well, then you are better off with a backup program.

  You must tap on the small set of lines in the lower right to get list view. Then you can find the city that you want to delete, drag to the left to see the button Delete.

• Time Machine will back up to two different computers on the same hard drive?

  I just got a Seagate Plus for Mac backup copy.  When I plugged it in, right away, he said "Would you use Time Machine?" (as opposed to included Seagate Dashboard).  I said 'Of course'.  It is then backed up my computer all with Time Machine.  So far so good.  But my wife also got an iMac, running OS 10.9.5 (don't ask!)  Can I plug the drive into his computer and ask Time Machine to back up?  Or who will crush the back-up, I just make my computer?

  TimeMachine will gladly be backup Mac on the same drive and separate them.

• How to use previous Versions to be like an instant Virtual Machine?

  I want to use previous Versions to be like snapshots of a virtual machine.

  I have a class of machines Windows 7 I want to freeze their condition so that they will restore a snapshot whenever I created whenever they have restarted.

  Right now I use Comodo Time Machine to make this work but I prefer to use "Previous Versions" or the system restore to make a machine to return to a State that I created any changes have been made.
