Putting long strings on a JLabel

I want to write a string on a particular rectangular region (e.g. JLabel) and the length of string is more than the width of the rectangle, so it wont fit in one line.
Is there any API that will automatically calculate where to put the line break and display it accordingly in multiple lines.
In other words, I want Java equivalent of VC++ function
Status DrawString(
const WCHAR *string,
INT length,
const Font *font,
const RectF &layoutRect,
const StringFormat *stringFormat,
const Brush *brush
);

Other than using an uneditable JTextArea (as suggested above), not APIs exist to do it automagicly.
You would have to use things like getStringBounds , adding one word at at time, until you go over the length you want, then roll back a work, add a new line, and do it all again.

GP - How to display a long string value

I'm trying to display a really long string value and then allow the user a couple of result state choices (to either go back and do another search or finish).
None of the forms (WD, display, etc.) will display a really long string.
I tried using a loop type decision dialog, but there doesn't appear to be a way of having it pick up a parameter value as the message (or part of the message) to display.
I can get it to display in the complex type decision dialog, but I don't need the group/options and I can't seem to get rid of the second set of buttons that show up (the long string parameter value was put into the 'Info Texts' area and does display ok).
Is there any easy way of displaying the complete contents of a long string value and have buttons for results states? I'd even be happy if I could just display the whole string and use a separate callable object for the choices.
Thanks,
Cindy

I think you should try calling a JAVA or ABAP Webdynpro as the callable object. As you know, we can display long texts in the webdynpro fields. Other alternative is an Adobe form as well.

Is there an easy way to convert a long string into an array?

I can convert a long string into a 1-d array by parsing and using build array, but I would like to know if there is a function to make this easier.
For example:
from/   aaaaaaaabbbbbbbbccccccccdddddddd         (string of ascii)
to/       an array that is 1-d with each element having eight characters
          aaaaaaaa
          bbbbbbbb
          cccccccc
          dddddddd
Thank you.
Solved!
Go to Solution.

Try something like this:
(If you can guarantee that the string length is an integer multiple of 8, you an drop the two triangular modes in the upper left. )

How to put a string from one Frame to another Frame?

Dear all,
How can I put a String from one Frame to another Frame?
When the application started, the Frame 'WindowX' will be displayed. After you press the 'openButton', a whole new Frame (inputFrame) will be shown. In this Frame )(inputFrame) you can write a String in a TextField. After pressing the okButton, this String will be sent to the first Frame 'WindowX'.
But does anyone know how to realize the sending part?
I've tested this code on Win98 SE and JDK1.2.2.
Hope someone can help me. Thanks in advance.
import java.awt.*;

Inserting long string into Oracle

When my code inserts about 5K character into a table, I got an error message saying that the Oracle could only handle 4K character. I am currently looking at LOB but havn't had a clear idea yet. Could someone give me some help on this? According to the sample code, I will have to use Oracle JDBC driver for LOB. But we are using BEA's Kona driver for all JDBC connections. Is there an easy way to insert long string?

hii
nams u solve ur problem using setCharacterStream method
but it does't work if the string more than 4000 char
raises "java.sql.SQLException: Protocol violation"
here's the code
PreparedStatement ps = con.prepareStatement( "UPDATE candidate SET cv_new = ?");
StringReader cvReader=new StringReader(cv_new);
int abc=cv_new.length();
ps.setCharacterStream( 1, cvReader, abc);
ps.executeUpdate();
is that any problem in that code or it's a jdbc driver broblem ??
i'm using classes 12.zip
thanks

How to find out if a long String has a "subString" twice or more.

I need to find out if a long String has the same number twice or more.
I need to look matches for numbers running from 000, 001....999 and if a number is found twice or more, return that number and lines there were found.
example String:
-;000 ; 1 ; 2006-12-11 ; -; job;
x;001 ; 2 ; 2006-12-11 ; 2006-12-12; do this
-;002 ; 3 ; 2006-12-11 ; -; work
-;003 ; 0 ; 2006-12-11 ; -; some
-;004 ; 2 ; 2006-12-11 ; -; thing
x;005 ; 1 ; 2006-12-11 ; 2006-12-11; reads
-;003 ; 0 ; 2006-12-11 ; -; here
Should return from example String:
003 at lines 4 and 7
Any ideas?

So there are newlines in the String?
You could use a StringTokenizer to break the String into lines, then searching on each line if it contains any of the search strings. (You need to clarify if a line can contain more than one search string).
Probably you should use a Map<String, Integer> to record the searchcounts.
Or an int[] Array if you are really sure that the Strings you search for really are numbers.
Another option is to use:
LineNumberReader lnr = new LineNumberReader(new StringReader(searchString));This will save you from explicitly having to take care for the line number.
In any case your example looks like the individual lines are semicolon separated fields and the numbers you search for always are in column two.
So after breaking up the original String in lines, you could use another StringTokenizer to break up the line in fields.

In report layout, can format a long string display as Column mode?

Hi,
Just want to check in report builder any way can format a long string into a column mode?
Example: I have a field to hold 8000 character, and would like to print
30 character in each line, when reach 50 line, then print in column i/o to print next page?
Any idea ? Thanks a lot if you can share your experience with me.
best Regards,
Klnghau

hi let say your field name is x
then if your want it word wrap then it's simple just get one field and make it's vertical
elasticity variable. and asign the field to it..
but if you want your field to be displayed as
first colunm and then beside continuation of that column but in 2nd one...
then create 2 formula columns make your field legth been distributed half in each.
so cf_1 is:
decalre
t varchar2(1510);
begin
if length(:x) > 1500
t := substr(x, 1, 1500); -- as 30 x 50 = 1500
else
t := :x;
end if;
return t;
so cf_2 is:
decalre
t varchar2(1510);
begin
if length(:x) > 1500
t := substr(x, 1500, length(:x)-1500); -- as 30 x 50 = 1500
else
t := '';
end if;
return t;
and then in design view
field1 field2
for field1 source is cf_1 and
for field2 source is cf_2
that's all
Enjoy Oracle...

OWA Email - One Long String

The email I receive from OWA has no line breaks, it is all one long string. This is creating a big problem when I forward the emails received with my BB as they are difficult to read by the recipient. Is there anyway to correct this? I use BIS and access my work email via OWA. I also have a separate personal email set up with no problems with the email I receive or send.
BB Curve 8310 v4.5.0.55
OWA v5.5 SP4
Any help will be appreciated!

I'm experiencing the same issue (no line breaks) when pasting rows directly from Excel (2008 & 2011) into a Flex TextArea on a Mac. However, when pasting the exact same data from a Windows Excel spreadsheet, it contains the line breaks.
From Mac: Customer\tPhoneCustomer 1\t555-555-5555Customer 2\t555-555-5556
From Windows: Customer\tPhone\rCustomer 1\t555-555-5555\rCustomer 2\t555-555-5556\r
This appears to be a bug in a flash.display class as pasting the data from Excel to a text editor and then copying/pasting into the same Flex TextArea preserves the original line breaks.
Has anyone figured out a work around?

Long strings in combo box

I have an editable combo box that I'm sticking in a compact spring layout. The problem is if you use a list that contains very long strings (like a long hex string), the combo box sizes itself to fit it and all the other controls are made to be that length as well. Is there a way to stop the control from becoming so long, like a horizontal scroll bar in the list?

How to indent the 2nd line of a long string?

Hi all,
I would like to achieve something like below where the 2nd line will be indented automatically. How to do format this in Oracle Report? The "<--indent-->" below is to illustrate the indentation, which I can't show in this posting as the formatting is not supported.
Okuda, M., & Okuda, D. (1993). Star Trek chronology: The history of the
<--indent--->future. New York: Pocket Books.
Please advise.
Thank you.

Yes, chr(10) can make the string break to next line, but that cannot fulfill my requirement.
What I need is a single long string that will automatically get indented for the 2nd line onwards when display in report.
I can't use chr(10) because I won't know when to break to next line because it does not have fixed rule that after which part should I break it to next line. I'm referring to bibliographic citation that normally display as indented for the 2nd line.
Hope you got what I mean.

Automatic trim of too long strings

Hi,
if I try to insert a too long string value into a VARCHAR column, I get the error ORA-12899.
Is it possible to set the Oracle database so that too long strings get trimmed automatically?
Thank you.

Hi,
Welcome to the forum!
Unfortunately, there's nothing quite like what you want in Oracle.
Even if you write a trigger to cut off the excess, you can still get the ORA-12899 error. For example, if table_x.col_1 is defined as VARCHAR2 (10), this statement:
INSERT INTO table_x (col_1) VALUES ('ABCDEFGHIJKLMNOP');will get the error, even if you have a trigger that says
:NEW.col_1 := SUBSTR (:NEW.col_1, 1, 10);You could define col_1 as VARCHAR2 (4000), and have a trigger that includes the statement show above, to make sure that the actual values will be 10 characters or less. You cound even have a CHECK constraint (LENGH (col_1) <= 10).
Think carefully about what Someoneelse said. Do you really want to throw away part of what users enter, automatically and without any warning? Will that cause confusion?
