How do I know the Column number after shifting table columns?

I create a table with column name "a", "b", "c"
Then I shift those column around..
Is there a way Java can tell me the column number of heading "b"? (For example)
Thanks!

As mentioned above you generally don't need to worry about columns being moved but, from the JTable API, this may be what you are looking for:
int convertColumnIndexToModel(int viewColumnIndex)
int convertColumnIndexToView(int modelColumnIndex)

How can i know the row number of my table is being modified?

HI all,
I have a table in my web dynpro and several columns as checkbox... I put an event OnToggle in these columns.
Do you know any way to get the row or the row number?
If i use the method get_static_attributes return to me the selected row not the modified.
Thanks in advance !

EDIT: thanks ! is solved, i need to pass CONTEXT_ELEMENT' in the <ELEMNT_NAME>
This is my code:
DATA table_element TYPE REF TO if_wd_context_element.
DATA row_index TYPE i.
table_element = wdevent->get_context_element('CONTEXT_ELEMENT').
IF NOT table_element IS INITIAL.
row_index = table_element->get_index( ).
ENDIF.

How can I know the target row in drop table?

I'm implementing 'drag-and-drop' a record from a table to another table(both are set read-only table).
After dropping, the record will be removed from source table and be inserted into target table.
But the problem is that it's not simply added.
When a record is dropped, it must be inserted right after target row which the mouse is over.
(Target table records have a kind of order number and re-ordering will be needed at each drag-and-drop)
I tried with EL from VO like '#{bindings.Testtbl2View1.currentRow}', but it returned a selected row before, not the target row(which mouse is over).
Please advise me.

How can i know the table fragments

Hi
How can i know the table is fragmented.
Thank you

If you're in 10g you could try use the Segment Advisor to identify various issues etc with your table. This will also provide recommendations on how to improve things.
(below script shamelessly stolen from the brilliant Oracle Base website)
-- segment_adv_table.sql
-- Use Segment Advisor to analyse a table.
-- Original Version
-- http://www.oracle-base.com/articles/10g/SpaceObjectTransactionManagement10g.php
-- owner is SCOTT
-- table is EMP
-- do a search/replace to change these 2 values and re-run it ;)
DECLARE
l_object_id NUMBER;
BEGIN
-- Create a segment advisor task for the SCOTT.EMP table.
DBMS_ADVISOR.create_task (
advisor_name => 'Segment Advisor',
task_name => 'EMP_SEGMENT_ADVISOR',
task_desc => 'Segment Advisor For EMP');
DBMS_ADVISOR.create_object (
task_name => 'EMP_SEGMENT_ADVISOR',
object_type => 'TABLE',
attr1 => 'SCOTT',
attr2 => 'EMP',
attr3 => NULL,

How can i change the column label text in a alv table display

how can i change the column label text in a alv table display??
A similar kinda of question was posted previuosly where the requirement was the label text was needed and following below code was given as solution :
* declare column, settings, header object
DATA: lr_column TYPE REF TO cl_salv_wd_column.
DATA: lr_column_settings TYPE REF TO if_salv_wd_column_settings.
DATA: lr_column_header type ref to CL_SALV_WD_COLUMN_HEADER.
get column by specifying column name.
lr_column = lr_column_settings->get_column( 'COLUMN_NAME1' ).
set Header Text as null
lr_column_header = lr_column->get_header( ).
lr_column_header->set_text( ' ' ).
My specific requirement is i have an input field on the screen and i want reflect that value as the column label for one of the column in the alv table. I have used he above code with slight modification in the MODIFYVIEW method of the view since it is a process after input. The component gets activated without any errors but while run time i get an error stating
"The following error text was processed in the system CDV : Access via 'NULL' object reference not possible."
i have checked in debugging and the error occured at the statement :
lr_column = lr_column_settings->get_column( 'CURRENT_YEAR' ).Please can you provide me an alternative for my requirement or correct me if i have done it wrong.
Thanks,
Suri

I found it myself how to do it. The error says that it is not able to find the reference object i.e it is asking us to refer to the table. The following piece of code will solve this problem. Have to implement this in WDDOMODIFYVIEW method of the view. This thing works comrades enjoy...
DATA : lr_cmp_usage TYPE REF TO if_wd_component_usage,
 lr_if_controller TYPE REF TO iwci_salv_wd_table,
 lr_cmdl TYPE REF TO cl_salv_wd_config_table,
 lr_col TYPE REF TO cl_salv_wd_column.
DATA : node_year TYPE REF TO if_wd_context_node,
 elem_year TYPE REF TO if_wd_context_element,
 stru_year TYPE if_alv_layout=>element_importing,
 item_year LIKE stru_year-i_current_year,
 lf_string TYPE char(x),
DATA: lr_column TYPE REF TO cl_salv_wd_column.
DATA: lr_column_header TYPE REF TO cl_salv_wd_column_header.
DATA: lr_column_settings TYPE REF TO if_salv_wd_column_settings.
Get the entered value from the input field of the screen
node_year = wd_context->get_child_node( name = 'IMPORTING_NODE' ).
elem_year = node_year->get_element( ).
elem_year->get_attribute(
 EXPORTING
 name = 'IMPORT_NODE-PARAMETER'
 IMPORTING
 value = L_IMPORT_PARAM ).
WRITE L_IMPORT_PARAM TO lf_string.
Get the reference of the table
lr_cmp_usage = wd_this->wd_cpuse_alv( ).
IF lr_cmp_usage->has_active_component( ) IS INITIAL.
 lr_cmp_usage->create_component( ).
ENDIF.
lr_if_controller = wd_this->wd_cpifc_alv( ).
lr_column_settings = lr_if_controller->get_model( ).
get column by specifying column name.
IF lr_column_settings IS BOUND.
 lr_column = lr_column_settings->get_column( 'COLUMN_NAME').
set Header Text as null
 lr_column_header = lr_column->get_header( ).
 lr_column_header->set_text( lf_string ).
endif.

Thank you

Welcome to the Apple community jorjh.
If you mean that Find My Phone is asking for a password to a different Apple ID to your current Apple ID.
This feature has been introduced to make stolen phones useless to those that have stolen them.
However it can also arise when the user has changed their Apple ID details with Apple and not made the same changes to their iCloud account/Find My Phone on their device before upgrading to iOS 7, or if you restore from a previous back up made before you changed your details.
The only solution is to change your Apple ID back to its previous state with Apple at My Apple ID using your current password, you don’t need access to this address if it’s previously been used with your Apple ID, once you have saved these details enter the password as requested on your device and then turn off "find my phone" and delete the account from your device.
You should then change your Apple ID back to its current state, save it once again and then log back in using your current Apple ID. Finally, turn "find my phone" back on once again.

How can we know the format of report

Developed a web application using java SDK.
How can we know the format of report that is is it a crystal report , PDF or excel or hyperling.
If it is crystal report then i use openDoc and the report is opened but if its a hyperlink or PDf i am not able to open the report .
Please help.
Thanks

Check the si_kind or so_progid property of object. You can use oInfoObject.getKind() to retrieve that.
a crystal report would return crystalreport a pdf would return pdf etc.

How can i know the number of lines in field-symbol internal table

how can i know the number of lines in field-symbol internal table

Hi,
If your field symbol has been defined as an internal table :
Use std describe as
Data: l type i.
describe <fs> lines l.
'l' will contain the number of lines as needed.
FYI
The size of this storage area in a field symbols depends on the number of table lines which is not fixed, but determined dynamically at runtime.

How can I know the name of instance (SID)?

Dear all,
After I install the Oracle client in my computer, I would like to change the tnsname.ora. However, I don't know the name of instance (SID) because I am not the one install the database and the DBA is gone. So, how can I know the SID name and the port number as well.
Best Regards,
amy

Hey,
The sid defaults to the database name.
http://www.adp-gmbh.ch/ora/misc/identifiers.html
you can find it by
select name from v$database;
or by
show parameter db_name (run this in sql prompt)
Run the above on the database server.

If you are using the JFileChooser to open the document, I would create another class with this included:
//initiate class variables
private File f;
//create JFileChooser
JFileChooser fc = new JFileChooser();
fc.setMultiSelectionEnabled(false);
fc.setFileSelectionMode(JFileChooser.FILES_ONLY)
//set the chooser to initialise File f with the file selected
int status = fc.showOpenDialog(null);
if (status == JFileChooser.APPROVE_OPTION)
f = fc.getSelectedFile();
public File getFile()
return f;
}
