Number of rows in a jtextpane

hi,
is there any way to limit the number of rows in a jtextpane, i am able to limit the number of chars entered in using the insertString method, but i also need to limit the number of rows, for example the user should not be able to enter more than 200 chars or go beyond 5 lines, i can catch the 200 chars but am having problems with the lines. i can detect when enter is pressed, using hashCode() but i have problems when dealing with the delete key, knowing when a row is deleted and with line wrap, since that's not a enter being pressed.
Thanks.

Sounds like you are already using a DocumentListener to control the effect of changes, which is what you should be doing. You need a method of determining the number of rows displayed in the JTextPane... do you have one? And I don't see what the problem is with deletes, I can't imagine a scenario where deleting a character could increase the number of rows displayed.

How To Restrict Number Of Rows For Multiple Group In Report Output

Hi ,
I have a requirement to restrict number of rows in report output.I have three different group , if i use same no of rows to restrict then output is as expected but if i want Deduction group should have 7 rows , earning should have 5 rows and Tax group have 3 rows in report output then XML tag is not working.
Below is the XML tag i am using -
First i have declare the variable to restrict the rows -
<xsl:variable name="lpp" select="number(7)"/>
<xsl:variable name="lpp1" select="number(5)"/>
<xsl:variable name="lpp2" select="number(3)"/>
For Each -
<?for-each:PAYSLIP?>
<xsl:variable xdofo:ctx="incontext" name="DedLines" select=".//AC_DEDUCTIONS"/>
<xsl:variable xdofo:ctx="incontext" name="EarLines" select=".//AC_EARNINGS[ELEMENT_CLASSIFICATION!='Taxable Benefits']"/>
<xsl:variable xdofo:ctx="incontext" name="EarTaxLines" select=".//AC_EARNINGS[ELEMENT_CLASSIFICATION='Taxable Benefits']>
<?for-each:$DedLines?><?if:(position()-1) mod $lpp=0?> <xsl:variable name="start" xdofo:ctx="incontext" select="position()"/>
<?if:(position()-1) mod $lpp1=0?><xsl:variable name="start1" xdofo:ctx="incontext" select="position()"/
<?if:(position()-1) mod $lpp2=0?><xsl:variable name="start2" xdofo:ctx="incontext" select="position()"/>
Report output is tabular form (one page has two column - Earning and Deduction ) . Tax group comes below earning group.
Deduction Group -
<?for-each-group:$DedLines;./REPORTING_NAME?><?if:position()>=$start and position()<$start+$lpp?>
<?REPORTING_NAME?>
<?end if?><?end for-each-group?>
Earning Group -
<?for-each-group:$EarLines;./REPORTING_NAME?><?if:position()>=$start1 and position()<$start1+$lpp1?>
<?REPORTING_NAME?>
<?end if?><?end for-each-group?>
Tax Group -
<?for-each-group:$EarTaxLines;./REPORTING_NAME?><?if:position()>=$start2 and position()<$start2+$lpp2?>
<?REPORTING_NAME?>
<?end if?><?end for-each-group?>
Please let me know in case additional detail is require.
Thanks in Advance.
Thanks,
Harsh

variable lpp2 is declare to restrict EarTaxLines -
<xsl:variable name="lpp2" select="number(2)"/>
This will help to restrict the no of rows on one page , if we have more then two tax benefits line then layout will roll over to continuation page.
As part of report output my expectation is if i restrict Earning , Deduction and Tax benefits to same no of line for example - variable lpp ,lpp1 and lpp2 have same value "number(2)" , we can see the layout is continue on next page (restrict every group can have max two lines) .This is the reason we have 4 header grid , deduction and Tax Benefit lines are rolled over to continuation page .But if we restrict different value for each variable then continuation page layout is missing .
When we tried for <xsl:variable name="lpp2" select="number(3)"/> value continuation page layout is not getting generate for both employee number .

How to set the number of rows displayed in a classical report at runtime?

Hi,
Our customer has several standard client hardware configuration and would like to enable end users to choose their 'display profile' at login time. This 'display profile' would contain predefined values for these hardware configurations and supposed to set various paramters that should define the number of rows displayed in a classical report region.
I tried to provide parameters on the report region but it refused to accept anything but numerical values. Is it possible to do this?

The link is to the closest linkable point in the documentation to the description of the Number of Rows (Item) attribute.
It sounds like you have been trying to enter—unsuccessfully—an item name or substitution string into the Number of Rows attribute. The Number of Rows (Item) attribute is the one that actually allows you to do this. Click on the flashlight icon beside it to get a list of items from the application.

About the number of rows used to map data in Xcelsius

Hi Everyone:
I am using web services to fetch data into Xcelsius. The information I got from web service will increase in time and what I suppose is when I run out of rows to get all data I must open my Xcelsius model and select a greater range of rows on each component to get all the data that the web service is bringing.
Is there an alternative to avoid modifying ranges of data in crontrollers when rows mapped are not enough for the data you are fetching from a web service?
It is a bit confusing, I hope I've been clear enough. I really really will appreciate your opinions. If possible give me technical explanations.
Thank you,
Skull
Edited by: skull_buck on Aug 6, 2009 7:40 PM

Hi Greg
Thanks for your fast reply.
What you suggested is exactly what I am doing now, and also I increased the number of rows allowed to map en Xcelsius which are 512 by default.
I would like to know now, how many rows are advisable to increase? Because I am using some components and you must specify for each one a certain number of rows.
I test mapping 3000 and even 6000 rows but the model is too slow and I was not able to export the swf file in any format.
Thank you again,

Number of Rows Displayed in a SQL Report Region

Hi,
Just wondering whether it is possible to control the 'Number of Rows' displayed under the 'Layout and Pagination' section within the Report Attributes page.
Basically need to know if I can programmatically control this or even better, can it be customized by the user as the user may want to see say 15 rows, 200 rows or 'All' rows of a certain region on the page. FYI, I have three different report regions on one page and want to give the user the flexibility to modify the number of rows displayed per region.
Thanks.
Tony.

Merging two separate Tables into One - different number of rows

Hi. I have a problem. Oracle 10.2.0.4.0
7 years ago when i was learning how to query my teacher told me that is possible to creata some kind of report where results could be combined in 1 view(report) witch in different variable could have different number of rows.
I just remember that there is needed to use group by function and some join?
Please help
In link there is a sample sample view
I need to combine Table A using D variable with Table B to become Wynik(result)
Tables create
CREATE TABLE "TABELA_A" ( A NUMBER,B NUMBER,C NUMBER,D NUMBER ) ;
INSERT INTO "TABELA_A" (A, B, C, D) VALUES (123, 1, 70, 999)

How to limit the number of rows in a report

I have several reports with a number of parameters - date ranges etc.
Depending on the parameter values selected by the user the reports can return thousands of rows.
I would like to limit the number of rows returned to, say, 500. If more than 500 rows are returned by the query then display an error message requesting that the user enter more specific parameters.
Ideally for performance reasons it would be good to catch the error before the datafile is generated, but I don't know if this is possible. Alternatively a check in the template might do the job - using COUNT on the group?.

Hi Hugh,
In your query, you got to add rowum < 500 or some sort of DB specific limit to the row being returned,
this will help to stop the report to get more than 500 records and the report template wont have any restriction.
or
you can do that in template too, but i would not recommend.
In these both cases or in any case, you cannot give any meaningful error if it exceeds N rows,there is no option like this till now.

Different number of rows for different columns in JTable

hi
I need to create a JTable with different number of rows for different columns...
Also the rowheight should be different in each column...
say there is a JTable with 2 columns... Col1 having 5 rows and column 2 having 2 rows...
The rowHeight in Col2 should be an integer multiple of Rowheight in Col1
how do I do this ??
can anybody send me some sample code ?????
thanx in advance

How about nesting JTables with 1 row and many columns in a JTable with 1 column and many rows.
Or you could leave the extra columns null/blank.
You could use a GridBagLayout and put a panel in each group of cells and not use JTable at all.
It would help if you were more specific about how you wanted it to appear and behave.

How to get number of rows

Hi!
Can someone tell me how to obtain the number of rows returned by a query?
I tried to use getFetchSize() but it seems to always return 0 for my query.
THANKS in advance!
ResultSet testRS = Stmt.executeQuery(testStmt);
int size = testRS.getFetchSize();
System.out.println("size = " + size);
Wo Lay

To get the number of rows returned, you have to loop
through the result set, or do a "select count" (which
is more efficient since it doesn't have to pass the
rows across the network) ...Looping around the entire result set is not very performance efficient. Then agin if you use count (*) you actually execute an extra query.
The best thing you can do is:// assume res is your result set.
res.last();
int rows = res.getRow();This way you only have to execute one query and you don't really need to loop around the entire result set. Of course you will have to have a scrollable result set, if this is supported by your DB.
Hope that helped.

Hi,
Initialise one variable TOT_ROWS to 0.
Then in the for loop
tot_rows := tot_rows + +1 ;
so after for loop the value in the tot_rows will be the total records..
If u want it to get this value in the calling procedure of this , just declare tot_rows parameter as out parameter.
For sum of a column:
Initialise a variable sum_col to 0.
In the for loop
sum_col := sum_col+I_info.column_name
aprameter if u wish return this value as out..
I think this wil give u the o/p..
cheers,

How to get number of rows return in SELECT query

i'm very new in java, i have a question:
- How to get number of rows return in SELECT query?
(i use SQL Server 2000 Driver for JDBC and everything are done, i only want to know problems above)
Thanks.

make the result set scroll insensitve, do rs.last(), get the row num, and call rs.beforeFirst(), then you can process the result set like you currently do.
         String sql = "select * from testing";
         PreparedStatement ps =
          con.prepareStatement(sql,ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
         ResultSet rs = ps.executeQuery();
         rs.last();
         System.out.println("Row count = " + rs.getRow());
         rs.beforeFirst();~Tim
NOTE: Ugly, but does the trick.

How to find number of rows in a table

i have one table ,it contains millions of record,how can i know number of rows in that table without using count(*),
i tried in user_table ,for the column NUM_ROWS,but it is not showing number of rows,pls send me a solution for this.

Ok, that only was to show simply that max option
might not an option to reduce execution time.Yes, but I/O variances have a tendency to really skew the observed elapsed execution time - making execution time alone a poor choice to determine what SQL will perform better than another.
Both MAX(ROWNUM) and COUNT(*) results in the same amount of I/O - as both uses the exact same execution plan, I/O wise. In this example, a FTS.
SQL> create table testtab nologging as select * from all_objects where rownum < 10001;
Table created.
-- warmed up the buffer cache with a couple of SELECTs against TESTAB in order
-- to discard PIOs from the results
SQL> set autotrace on
SQL> select count(*) from testtab;
COUNT(*)
10000
Execution Plan
Plan hash value: 2656308840
| Id | Operation | Name | Rows | Cost (%CPU)| Time |
| 0 | SELECT STATEMENT | | 1 | 35 (9)| 00:00:01 |
| 1 | SORT AGGREGATE | | 1 | | |
| 2 | TABLE ACCESS FULL| TESTTAB | 9262 | 35 (9)| 00:00:01 |
Note

SQL> select max(rownum) from testtab;

10000

| Id | Operation | Name | Rows | Cost (%CPU)| Time |
| 0 | SELECT STATEMENT | | 1 | 35 (9)| 00:00:01 |
| 1 | SORT AGGREGATE | | 1 | | |
| 2 | COUNT | | | | |

So seeing that we have the exact same baseline for both queries, and that PIO does not influence the results, we time a 1000 executions of both.

This shows that what makes the MAX() more expensive is just that - determining the MAX(). For each row, Oracle has to call its internal MAX() function with two values - the current max result and the new value. This function then returns the new max value. This overhead per row adds up to a significant overhead in execution time - making the MAX() approach 5x slower than the COUNT() approach.

How to restrict number of row/lines in a table in RTF

Hi,
Im working on PO report. It has header information in the header part of RTF. But coming to the lines , I put that under a different group in the table in the body part of the RTF. I did a FOR loop for printing PO Lines because it does have multiple line information. But now i have to restrict the number of rows in that table per page irrespective of number of PO Lines. After printing 20 rows in the table, it should go to the next page. Im going through the other threads for the solution.
Thanks,
venkat

There are so many thread regarding this ,
pls go thru them patiently...
logic is something like....
use if condition and position() and say page-break..
use for-each@section instead of for-each..so that the headed info is maintained with regards to PO lines
happy searching...
if you cant get still, last option send me mail with details
