How to limit characters entered in JTextField

Hi,
How can we limit character entered in JTextField.
1.) I know its posssible with JFormatedTextField...
2.) I can do this by creating a child class of JTextField.....
But there must be an easy way (sun guys would have included some methods to limit characters entered)
Any one know any such methods...?
Thank You
Ashish P.J

Read the API for JTextcomponent and follow the link to the tutorial where you'll find a working example of using a DocumentFilter to achieve this.

How to limit to enter a IP address in TextField?

Hello everyone,
I have a PDF form which users need to enter a IP address. In order to get a correct IP address, I need to limit a TextField's pattern.
What my boss want me to realize is like the picture below:
It means when users fill 3 numbers of IP address, it will jump to next place and display a point "." automatically.
But I found it can't change the rawvalue of the TextField when it is in a typing status(in Change event).
Do you think if I can realize this requirement? How can I do ?
Thanks a lot!
Elly

Hi,
you can use a regular expression to verify the entered text.
This script in the fields exit event, will check the entered text against a regular expression.
if (! this.rawValue.match(/\b(?:(?:2(?:[0-4][0-9]|5[0-5])|[0-1]?[0-9]?[0-9])\.){3}(?:(?:2([0-4][0-9]|5[0-5])|[0-1]?[0-9]?[0-9]))\b/ig)) {
xfa.host.messageBox("invalid IP-Address");
Here`s a source for regular expression you can try.

How to limit characters

I've got DW8 retrieving a text chunk from SQL Server/ASP and
I need to
restrict it to the first 300 characters. Is there a way in DW
to do this?

Use this for your source
SELECT LEFT(mycolumn, 300) FROM mytable
Depending on the datatype of the column, you may have to
convert (CAST) to varchar first.

How do I limit number of characters in a JTextField?(different from others)

Hi,
I know this question has been posted several times on this forum, but my question is actually a different one. So please read.
I have the following code that puts two JTextFields in a JFrame. I want to limit the number of characters in the first JTextField to three characters. What's different about my question from other solutions provided, is that I don't want to be able to type more than three characters in the JTextField, and then not be able to get out of JTextField unless I have three or less characters. What I do want, is to have maximum of three characters, not be able to type the fourth, and have access to the other JTextField at all times.
I have tried the following solution of setting an InputVerifier to my JTextField, but it hasn't worked, since I can still type the fourth character.
Looking forward to your help!
Thanks.

Thanks, JayDS! Your suggestion worked. And I've come up with the following code with help of your suggestion. However, I'm not happy with the fact that I see empty spaces in my JFormattedTextField when I don't have anything entered in it, or when my textfield has focus and I click it again. Also, I'd like the text alignment to always stay on the right, even if I have less than 3 digits.
Could you please help me out with that?
Thanks!

How to get character entered in JPasswordField

Hi,
I am using a JPassword field and i need to get the password entered(i mean the characters entered)
getText() is depricated so i used getPassword(), but it gave me some other things (%@$#) for what i entered (abcd).
1) How can i get the exact character. Like if i type "abc" i want to get "abc".
Thank you

Yes, but I would think twice about storing the password in the database. That kind of defeats the purpose of having a password. Anyone with basic knowledge of SQL can find it.
There are some tricky things you can do such as using a hash to make the password illegible in the database, then you would reverse the hash in your program when you read it back again. But even this is not real secure.

How to limit the number of boxes to tick in LC

I would like to know the "javascript" in Lice Cycle to limit the number of boxes ticked
for example i have 20 boxes and i would like that the client can only tick 5 boxes
thank you

Thank you Steeve
But my problem is that i don't know which boxes the client will want to tick so all boxes have to be available at the beginning.
When the client will have ticked 5 boxes in this case and only in this case, all others boxes must become unavailable so it is very difficult to set up
if you have any idea
thanks anyway

Subject: How to limit the number of boxes to tick in LC
This is a form validation issue. For example, you may have a text field and the value entered into that field determines which checkboxes must be completed to satisfy a validation or business rule. The attached sample requests the value "foobar" to be entered into a text field. If you enter "foobar" and exit the field, 2 of 3 checkboxes have the access property changed to "protected", meaning a user cannot no longer select those checkboxes.
// form1.page1.subform1.input::exit - (JavaScript, client)
if (this.rawValue == "foobar") {
form1.page1.subform1.cb2.access = "protected";
form1.page1.subform1.cb3.access = "protected";

Hi...
I am information technology student. I am now first
year second semester
I need help because I don't know how to catch the
enter key in JTextField.it can be done easily by adding an actionListener to the JTextField. So when u enter something in the field and press enter the event will be caught and the code which u write in that will get executed.
Eg:
JTextField.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
Your code comes here.
Another thing is
"How to add a JMenuItem into a JMenuItem...."

How pass ext characters to a stored proc by odbc when enable sqlserver syntax is on??

how pass french characters or extended characters to a stored procedure by odbc
error: ORA-01756: quoted string not properly terminated
une chaine entre apostrophhes ne se termine pas correctement
oracle Retrieving extended characters thru ODBC
PL/SQL procedure parameters
hi, i hope you can help to me.
I have a problem with french and german characters.
i have a little stored procedure than return what i'm passing to him.
see these example: (the second one work fine on plsql)
first exemple:
1) i created a new odbc dsn
2) i'm going into sqlserver migration tab to choose
Enable Exac Syntax.
3) i'm open Winsql (this is a odbc tools)
http://www.indus-soft.com/winsql/
4) i'm write
exec ksp_test 0,'HiLLO ORACLE'
i receive this error:
Error: ORA-01756: quoted string not properly terminated
(State:S1000, Native Code: 6DC)
I trying to changed too the NLS_LANG in the registry
like FRENCH_CANADA.WE8ISO8859P1
French_France.WE8ISO8859P1
but without any success..
i got the same problem with
oracle 9 database with utf8 characters set.
oracle 8.1.7 with iso8859p1 characters set.
i trying all latest odbc driver from oracle website.
second exemple:
SQL> variable mytest refcursor;
SQL> exec ksp_test (0,'HiLLO ORACLE',:MYTEST);
PL/SQL procedure successfully completed.
SQL> PRINT MYTEST;
Your Database Value
HiLLO ORACLE
CREATE OR REPLACE PACKAGE KSP_PLSQLRSETPKG
AS
TYPE RCT1 IS REF CURSOR;
END;
CREATE OR REPLACE PROCEDURE KSP_TEST (
PATCH INT DEFAULT 0,
PONC VARCHAR2,
RC1 IN OUT KSP_PLSQLRSETPkg.RCT1
AS
BEGIN
OPEN RC1 FOR
SELECT PONC "Your Database Value" FROM DUAL;
FROM DUAL;
RETURN ;
END;
i'm trying also different nls setting but no good result.
AMERICAN_AMERICA.US7ASCII
AMERICAN_AMERICA.WE8MSWIN1252
FRENCH_CANADA.WE8DEC
FRENCH_CANADA.UTF8
FRENCH_CANADA.WE8MSWIN1252
FRENCH_FRANCE.WE8DEC
FRENCH_FRANCE.UTF8
FRENCH_FRANCE.WE8MSWIN1252
is working well on sqlplus but not by odbc..
also..
i'm declare a variable and
i set
v_variable := 'id'
and the procedure return the good syntax...
i think is a odbc driver problem....
the driver don't want to accept a extended characters set by a parameters coming from the procedure.
can you confirm to me ..this is a major bug for the driver..
my procedure is very basic to make a little test.
did you try my procedure to be sure you have the same problem?
i try with a oracle instance utf8,WE8MSWIN1252 and
i got always the same problem.
if i write insert into test values ('di');
everything is fine...but when i call the procedure...
the procedure don't want to accept any german..french or any extended characters...
our application is working by odbc driver.
i'm pretty sure is a bug in the driver ...the bug is coming only when i select "ENABLE EXEC SYNTAX" IN THE DSN (SQLSERVER MIGRATION SECTION) ... i try with Shema Database and Owner and Empty and i got
always the same problem
exec KSP_TEST 0,'TiEST'
------------------------>>>>>>>NOT WORKING.
BUT IF I WRITE
CALL KSP_TEST (0,'TiEST')
------------------------->>>>IS WORKING
if i select enable exec or i unselect enable exec...
the CALL KSP_TEST...... is always working properly.
BETWEEN THESE SYNTAX THE NLS_LANG IS NEVER CHANGED....
IS WORKING.....THE NLS_LANG IS GOOD.......because i make a little modification in procedure to be sure the INSERT IS inside the database CORRECTLY.
CREATE OR REPLACE PROCEDURE KSP_TEST
PATCH INT,
PONC VARCHAR2
AS
v_test varchar2(100);
BEGIN
v_test := 'test';
INSERT INTO YYY VALUES (PONC);
END;

If "just using Crystal Reports XI R2" means using Crystal Report Viewer and do not want to see the prompt, please follow the below steps.
1. Select the report you want to see
2. Select "Process" tab
3. Select Parameters menu under the process tab.
4. You would see two date parameters there.
Select the [Empty] value for each parameter and fill out the value you want.
Hope this would help.

How to limit the max dialog no that one user can use at the same time?

Hi,
I meet one performance problem that one user can open 6 sessions in the GUI and he/she can run 6 reports at the same time witch could occupy 6 dialogs in the sap R/3 instance. It makes poor performance for other users.
Would you pls tell me how to limit the no. of sessions one user can create at the same time or how to limit the no. of dialogs one user can occupy at the same time?
Thanks a lot!
I used this parameters in the default profile as blew:
rdisp/rfc_check 1
rdisp/rfc_use_quotas 1
rdisp/rfc_max_own_used_wp 20 (means: 20%)
It still didn't work.
Sean

Hello,
We can reserve DIA W.P by giving value to the parameter :- rdisp/rfc_min_wait_dia_wp=1(default)
that have to necessarily remain free for other users.
This parameter is used to reserve a number of dialog work processes for Dailog mode.
For eg. If 10 dialog w.p. are configured for the instance(rdsip/wp_no_dia=10) and the parameter rdisp/rfc_min_wait_dia_wp=3 is set,parallel RFC's can occupy a maximum of 7 DIA W.P.3 DAI W.P. always remain free for dialog mode.
But now the question is how we assign/restrict this free dialog w.p. to the specific user.
