REGEXP_REPLACE - replaceing a character not allowed
Hi friends,
Please, help me to replace a character not allowed of a given string. Allowed characters are
abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789/ -?: ()., "+ {space} "
If a character in the specified string is not in the list above, which should be replaced by a space. Can you please help me to do with REGEXP or in any other way.
Thanks in advance!
In my previous solution the dash (-) in the second row replaced with space. That shouldn't be the case. This is because the brackets, hyphen is considered operator of range as [0-9]. So I moved the link to the last to solve the problem.

How to find and replace data in fields of form in acrobat xi, its not allowing to do while trying, request adobe livecycle to settle. Help, please.
Best way to do is the following:
-Open the PDF in Acrobat.
-Go to tools - form - form more Options - export data.
-Save form data in an XML file somewhere on your system.
-Open the XML file in a plain text editor (I recommend Notepad ++).
-Let's say you want to replace all the years in dates "2013" to '2014 '. Do a global search & replace '2013-' to '2014' - (I added the dashboard in order to ensure that only the date fields are changed).

InDesign CC Grep find/replace to replace the character of space per paragraph (fly)
Hello InDesigners,
I'm trying to clean up a 99 page document. In the file, titles of chapters, in capital letters, followed by a space, which is then followed with text more uppercase there. This always occurs at the beginning of a paragraph.
I'm trying to target the space character that appears just after the number of chapter and Exchange to a number (fly).
For example:
CHAPTER 22 SUNDAY UNDERGROUND
I want the Grep to change this as follows:
CHAPTER 22
SUNDAY UNDERGROUND
I know that to do this job, I need to use positive look behind and positive Look Ahead, at first, I just tried to isolate CHAPTER 22 using the following:
^ \u{2,}\s\d+
It worked. However, as soon as I cut and paste into P.L.B., find/replace says that it does not match.
(?<=^\u{2,}\s\d+)\s
The culprit seems to be the comma that comes just after the number 2. If I take, I get a match, but just not the one I wanted.
Why P.L.B. does not accept the comma as part of the range in my definition grep?
(FYI, I prefer to use wildcards with a specified scope, rather than literal text).
It is indeed the comma, and the reason why it does not work because the flavor of InDesign's GREP does not allow a variable length argument in its lookbehinds. And the construction "has {x, y}" indicates a variable length.
"Chapter" only you know how many characters to uppercase, and even the exact text, you can use
(?<=^CHAPTER>
the first chapters to a number, then
(?<=^CHAPTER>
for the rest. In your version of InDesign, I guess there is also a possible solution with the fairly new \K "forget - me" operator but I have not yet enough experience with that. It should look like this:
^ \u{2,}\s\d+\K\s
but you will have to experiment a bit to see how to work with the replacement string.
In addition, you should only use the name of "fly" for a character that looks like this: "¶". The code that you insert will call it a 'return' or 'paragraph return. Initially, I took your question literally, and it sounded as if you were after this result: "CHAPTER 22 ¶ SUNDAY UNDERGROUND"

XmlValidate() - the content is not allowed in prolog
I posted in another thread, but I think that the problem described, it is resolved, so I'm starting a new thread with this new number.
XmlValidate always returns "content is not allowed in prolog" I searched this forum and google and I've seen where this problem has been solved for some. It seems that the most common cause was a hidden character (BOP I think) in the file. However, I checked that my xml has not just in it.

Click on the folder and change your permissions for it and all subfolders and files all rights and if necessary take hand the case (and maybe the parent folder or even its parent - and all of the subfolders and files) until you have the permission you need. Here are the general procedures to help you:
To view your permissions, right-click on the file/folder, click Properties, and check the Security tab. Check the permissions you have by clicking on your user name (or group of users). Here are the types of permissions, you may have: http://windows.microsoft.com/en-US/windows-vista/What-are-permissions. You must be an administrator or owner to change the permissions (and sometimes, being an administrator or even an owner is not sufficient - there are ways to block access (even if a smart administrator knows these ways and can move them - but usually should not because they did not have access, usually for a very good reason).) Here's how to change the permissions of folder under Vista: http://www.online-tech-tips.com/windows-vista/set-file-folder-permissions-vista/. To add take and the issuance of right of permissions and ownership in the right click menu (which will make it faster to get once it is configured), see the following article: http://www.mydigitallife.info/2009/05/21/take-and-grant-full-control-permissions-and-ownership-in-windows-7-or-vista-right-click-menu/.
To resolve this problem with folders, appropriating the files or the drive (as an administrator) and give you all the rights. Right-click on the folder/drive, click Properties, click the Security tab and click on advanced and then click the owner tab. Click on edit, and then click the name of the person you want to give to the property (you may need to add if it is not there--or maybe yourself). If you want that it applies to subfolders and files in this folder/drive, then check the box to replace the owner of subcontainers and objects, and click OK. Back and now there is a new owner for files and folders/player who can change the required permissions. Here is more information on the ownership of a file or a folder: http://www.vistax64.com/tutorials/67717-take-ownership-file.html. To add take ownership in the menu of the right click (which will make it faster to get once it is configured), see the following article: http://www.howtogeek.com/howto/windows-vista/add-take-ownership-to-explorer-right-click-menu-in-vista/.

You are not allowed on this computer to install Kodak printer all in one
I have a kodal while a printer installed. When I try to print it will only allow me to print sizes THEY have. If click Custom to select the paper size, I really want to use it, says this feature is not available because you are not allowed to save the settings for this computer. I went to the permission settings and everything that the printer is checked with the exception of special permissions which it does not allow me to click on.
You might want the laptop computer and the other computer (with a crossover cable) network and then share the internet connection. Not only will you get operational, but will give you access to the internet without having to replace the modem (as long as the laptop is present and connected). Otherwise, you have no choice but to replace the modem and get this computer connected to the internet, then you can install your device - there is no way around that need to be connected while doing if this is required by the software.
I hope this helps. I'll help you set up the network, if you want to go this route.
