How can I change new line to br tag in text post by textarea?

Dear all,
My problem is listed in the title.
I'm new in jsp, so please help me.
Any help would be appreciated and thanks in advance.
Regards.

String#replaceAll() does exact the same, but the author of that article apparently didn't know about that in spite of that it is already introduced in JDK 1.4.

How can you change your line access selection? I have found where you can change your plan selection, but can you change the line access fee or is that a set amount?

DIVAB71,
Great question. The line access fees for the account are a set amount and can not be changed unless you are going from a basic to a smartphone or vice versa. If you are wondering about adding the month to month discount if you are out of contract Ann154 has provided great information on how to access and add the feature.

How can I change the space between a checkbox and text all at one time? I have a lot of checkboxes in my form.

How can I change the space between a checkbox and text all at one time? I have a lot of checkboxes in my form.

Okay, I haven't found a way to add an extra space using Find/replace, but you might be able to add some text wrap to the check boxes that will push the text away from them.
Open Find/Replace and click the Object tab.
Click the Specify attributes to find button to the right of the Find Object Format: field.
Under Basic Attributes, choose Stroke and then the Black swatch (assuming the black swatch is applied to the strokes of your check boxes). If there are no other stand-alone objects in your form with a Black stroke, this should be all you need. (If there are Black strokes on your table cells, they will be ignored.)
Click OK
Click the Specify attributes to change button to the right of the Change Object Format: field.
Under Basic Attributes, choose Text Wrap & Other > Text Wrap > Type: > Wrap around bounding box (2nd button from left)
Under Offset, set a Right offset at the distance you'd like to add (I don't know what units you use, but the 3-5 points might work for your purposes...might take some trial-and-error to get it where you want)
Click OK
Click Change All

How to add EOL(new line char) to JCheckBox's text??

I need to add new line char to JCheckBox's text.
I have a string and I am adding new line char("\n") to that. Then I set that string as the text for JCheckBox. But it is not adding a new line. If you know the solution to this problem, please let me know.
thanks
amit

hi artntek,
thanks works well. However Since I have 3 or 4 lines (might have even more) of text for JCheckBox, JCheckBox is aligned to middle of text. Is there any way to align it with the top of the text??

How can I change the language of a block of text

Hi,
Working in a bilingual environment, I am constantly switching languages as I write e-mail. Using Mail 3.5, if I forget to change the dictionary language before I start writing, Mail logically marks most words as spelled incorrectly. After having written a paragraph, I'd like to be able to change dictionary language, and then continue writing.
But Mail doesn't seem to change the language for the text that was already entered -- the words that were "misspelled" according to the old dictionary language are still underlined in red after the new dictionary is chosen, and after I've told it to "Check document now".
How can I get it to re-evaluate the text as now being in the language of the dictionary, so that all those incorrect red underlines will disappear?
Thanks,
Eric Peters

"It's not a bug or a feature; it's just something you can't do..."
Phooey! I accept that Mail is limited to one language at a time. I don't accept that the spell checking fails to work if I switch which dictionary is in use after having already written some text.
"I know of no email client for Mac than can do it, either."
Er, I hate to say it... MS Entourage does do it, perfectly.
I recently gave up Entourage and switched to Mail, because I decided to stick to all Apple software so that syncing would be smoother. The syncing does work much better now that I've eliminated Entourage from the equation...
...but why can't I switch languages and get the dictionary to evaluate the text in the language I've chosen?! Otherwise, can someone explain to me the meaning of allowing the user to select a new language from the popup in the "Show Spelling and Grammar" dialog, if that new language won't then be used for spell-checking, whether for all the text, or the selected text? What is the purpose of allowing use of an interface control which doesn't then do what it obviously is supposed to do? It seems like Apple has broken its own HIG here.
Thanks for listening... maybe someday it will work as it obviously should!

How can I add a line to my CSS file to have all TextArea fields show PRE

Hi,
I would like all my TextAreas to show the text as it was inserted into the database... with the new lines, tabs, etc...
I would like to add a line to my CSS file to do this if possible.
Thanks, Bill :>)

Thanks for all the input!
Fab. You have been talking about a report the whole time... I have been talking about one Database ITEM that is "Displayed as Text".
In a report the replace() always works in all browsers I believe... and I had no problem.
BUT, in a text ITEM I wasn't able to get anything to work..
So, I created a report region and retieved this one column (item) and selected a borderless region and it is fine...
select     replace(LAST_ACTION,chr(10),'<BR>') "LAST_ACTION"
from     "HT_ISSUES" "HT_ISSUES"
where issue_id = :P7_ISSUE_ID
I still would like to know how to Display as Text - as it is in the DB.
When have a Dispay as Text Item and I view Source when running the page.. it is correct in the source delivered to the browser but displays all one line.
(I save a SQL statement to the field)
[tr>[td colspan="6" rowspan="6" align="left">[span class="t3NoLabel">Last Action Item[/span> [br>Maintenance Issue - SELECT *
FROM (SELECT ROWNUM row_num, empno, ename, job, mgr,
hiredate, sal, comm, deptno
FROM emp)
WHERE row_num BETWEEN NVL (:p7_row_from, 1)
AND NVL (:p7_row_to, 1000000)

FAQ: UI - How can I change the color theme, size of the text, or turn off the application frame?

CHANGING THE INTERFACE COLOR SCHEME:
The Photoshop CS6 default interface is dark, but if you prefer the lighter interface you are used to from earlier versions,
you can change it back in the appearance area. There are 4 default color themes.
Mac Photoshop > Preferences > Interface
Windows Edit > Preferences > Interface
CONFIGURING LARGER FONTS:
For those who need larger fonts, you can also change the UI Font Size down in the type area.
Be sure to restart Photoshop to see the changes.
TURNING OFF THE APPLICATION FRAME
CS6 opens now by default in "Application Frame". You can go Window>Application Frame in the main meu and uncheck this

Select the title / text and then click on the "i" (inspector). A colored pin wheel shows up after you click on the square box directly below the font settings inside the inspector window. Then simply drag the dot to the color you want. Like this:

In PSE 12 how can I change my watermark label eg colour of text from black to white etc

I have created a watermark to use in batch processing from RAW to jpg but I don't like the watermark and want to change some elements eg change the text from black to white but every time I change it, PSE changes it back to black - how do I fix this?

This isn't Lion-specific. I had the same prob changing OS a couple of years ago and now again changing to Lion on a new laptop.
Changing the Date and Time settings would do it (you'd think) but it doesn't. It was always embedded in International (now Language &Text). It seems to be a bug though as I've Custom Edited selecting 12-hr clock with am/pm and have the same issue. On-the-hour has no am/pm or zeros.
I've learnt not to waste too much energy on it once it doesn't make logical sense as it's generally a bug.
I'm loving Lion though - even unexpectedly using the natural scrolling.....but I digress....

How can I change the font in which my emails text are recieved

Regardless of what font style I choose when compiling an email it is always recieved by the recipient in the same default not very good style, I cannot find anywhere under options etc where I can change this. I did not have this issue when using Outlook Express on my previous computer.
regards
J.A.Smith

If you're concerned about setting a specific font in outgoing messages, then I think the Stationery add-on will be useful to you. You can set up a template with explicit font specifications (but do bear in mind that not all fonts are available on all computers. We don't all use Windows!)
My experience is that the default html formatting in Thunderbird sets the size but not the face. Your recipient's email client, not being able to find a formal font request, will offer up whatever its default is set to, often Times Roman on a Windows system.
https://addons.mozilla.org/en-US/thunderbird/addon/stationery/
The trouble with this add-on is that it gives you a means to employ templates, but leaves you to your own devices to generate or obtain any. Most users would already be using stationery templates acquired for use with OE and wouldn't be concerned with creating their own.
I use one that contains this:
<code>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<style type="text/css">
body {
text-align: left;
font-family: sans-serif;
font-size: medium;
color: black;
background-color: white;
</style>
</code>
You can insert specific font faces and sizes to suit.

How can I change my power regulator to a new one?

In august 24,2010, I bought a macbook pro 13-inch from apple on-line store. But today, my power regulator of magsafe was broken. I don't know what's wrong with it. I use my friend's magsafe, and his magsafe is good. So I want to change another. How can I change a new magsafe? If I post this broken magsafe, what information must be post with magsafe? You can check my purchased on this account last month. Thank you

Welcome to Apple Discussions
You need to go to your nearest Apple store with your receipt and show them the busted MagSafe and ask for a replacement. This is just a Forum of users assisting users we can't do anything about hardware warranty claims and replacements.

HT204053 there is a new email on my phone apple id when I try to make an app purchase my own apple id does not work. How does this happen and how can I change it back?

There is a new email address on my phone in the apple id password box. My password will not work. How did this happen and how can I change it back?

Of course your password shouldn't work on a different Apple ID. This can happen for many reasons, no worries, just sign out back back in using your own ID.

When I create a New Folder (on the desktop or in Finder), the system uses the Generic Document Icon instead of the Generic Folder Icon. How can I change this back?

When I create a New Folder (on the desktop or in Finder), the system uses the Generic Document Icon instead of the Generic Folder Icon. How can I change this back?
All of a sudden I noticed that most of the folders on my computer were no longer using the folder icon, but the generic document icon. I had to manually change back the icon being used by opening Get Info for each folder and copying and pasting the generic folder icon from some folders that remained unchanged. Now whenever I create a New Folder (right click -> "New Folder"), the icon that shows up is the generic document icon (white page with top right corner turned down). And I have to manually change it so it shows up as a folder in Finder or on my desktop. I don't know why or how this switch happened. All of the folders now on my computer look ok, but I need to change the default so when I create a New Folder it uses the correct icon.
I have also Forced Relaunch of my Finder and rebooted the system. I downloaded Candybar but am not sure what will fix anything, so I haven't proceeded.
Anyone know how I can do this? Thanks.

Anyone?

You changed the order of the menu for "Open in a new window" or "Open in new Tab", How can I change it back? Or how can I omit any reference to tabs? I do not use them at all.
