How to add an data in an existing file

Hi, I have the following problem:
I am implementing a data logger using the RS232 port and Labview, I have not problems with data capture my problem occurs when I store the data in a file, I need that every time the data is registered this data must be updated in the file
How do I can do this?

If the data file is some type of delimited text (tab-delimeted text, csv, etc) you can just use the Write to Spreadsheet File.
Just make sure you wire True to "Append to File?"

Hi,
There is no function module for that, We have created our own function module and attached to that field.
Refer the below code. This will fetch the document number.
DATA: lwa_item   TYPE dmee_paym_if_type,
        l_fpayp   TYPE fpayp,
        l_fpayhx TYPE fpayhx,
        first_flag TYPE c,
        lv_lifnr   TYPE lifnr,
        voucher_id TYPE string,
        voucher TYPE string,
        invoice_id TYPE belnr_d,
        voucher_len1 TYPE i,
        voucher_len TYPE i.
TYPES:
BEGIN OF lt_regup,
        xblnr TYPE xblnr1,
        belnr TYPE belnr_d,
END OF lt_regup.
DATA: lt_regup TYPE STANDARD TABLE OF regup,
        lv_regup TYPE regup.
Hope this helps.

Hi,
First upload the file into an internal table. If you are using a file that is on application server. Use open dataset and close dataset.
Then :
Loop at it.
*insert or modify as per your requirement.
Endloop.

How to add a user to an existing group????

Can't seem to find how to add a user to an existing group (staff). I am trying to share data (rw) between my admin account (root) and a development user. On any other UNIX system I would just add the user name in the /etc/group file & logout/login in. It don't work here!
Suggestions??
thanx
mt

OS X doesn't use /etc/groups. This file is present but does nothing AFAIK.
Leopard uses directory services to handle groups and users.
membership in groups with GID>500 can be handled from GUI in system preferences->accounts. other groups can be handled from terminal with dscl (directory services command line). do man dscl for details.
to add a user to a group you'd do
sudo dscl . append /groups/groupname GroupMembership username
However, there should be no need to do it with "staff". every user with an account on your computer is a member of staff by default.

This is what i did
1) created a dummy file in c drive
2) copy pasted below lines, you can play around more with the format
set _my_datetime=%date%_%time%
set _my_datetime=%_my_datetime: =_%
set _my_datetime=%_my_datetime::=%
set _my_datetime=%_my_datetime:/=_%
set _my_datetime=%_my_datetime:.=_%3) Rename the file from dos
ren some.txt dummy_file_%_my_datetime%.txt4) Here goes the output
C:\dir
dummy_file_Mon_09_20_2010_161347_21.txt
Most of the code i copied from above url, you can tweak a little bit based on ur requirement and format.

[Ai-CS4] How to add an art board to existing document ?

hi all,
can anybody suggest me how to add a new artboard to existing document? I didn't find any ArtBoard Palette in CS4. But in CS5 it is given.
thanks,
D.A

The Artboard panel is new to AiCS5. In CS4, a new artboard can be added by doing either of the two:
1. Pick the Artboard Tool and click-drag it in the canvas area of the Illustrator document.
2. Pick the Artboard Tool, click on the 'New Artboard' button in the Control Panel. Then select the desired size from the list of Artboard Presets in the Control Panel and then click in the desired area of the canvas to add a new Artboard.
Hope this helps.

How to add one date column and charecter column

hi all,
i have 3 column start_date(date),end_date( date),duration (varchar2)
i am trying to add start_time and duration like this
end_date := to_char(start_time) + duration;
but its showing value_error
how to add one date column and charecter column.
Thanks

you need something that does:
end_date (DATE) := start_date (DATE) + <number of
days> (NUMBER)Not necessarily, because if the duration is just a string representation of a number then it will be implicitly converted to a number and not cause an error
e.g.
SQL> ed
Wrote file afiedt.buf
1 with t as (select to_date('01/07/2007','DD/MM/YYYY') as start_dt, '3' as duration_days from dual)
2 -- END OF TEST DATA
3 select start_dt + duration_days
4* from t
SQL> /
START_DT+

How to add TIMESTAMP data type in Enterprise Architect...?

Hi all
There is no data type of timestamp in Enterprise Architech. There is only
DATE type. I have ERD prepared from Enterprise Architech. How to modify
DATE type to TIMESTAMP type.
How to add TIMESTAMP data type in Enterprise Architect or in ERD ?
Thanks in advance,
Pal

Have you asked this question of the vendor of Enterprise Architect? They may have a later version that supports the various TIMESTAMP data types. If your ERD tool doesn't support a data type, other than talking to the vendor or working around the problem (i.e. generate DDL to a text file and edit it before applying it to the database), you're probably out of luck.

Does anyone know how to Add a date drop down list to a pdf file?

Can someone tell me how to add a Date drop down list in a form

There's no built-in function that does that in Acrobat, but there are some third-party tools that do.
The two most known ones are by FormRouter, which is free and based on form fields (but also a bit buggy), and a non-free version created by Max Wyss, which is based on a dialog object.

I would actually question whether or not more disks increase the risk of a disk failure. One disk can break as likely as one of two of more disks.
Simple stats. Buying 2 lottery tickets instead of one, gives you 2 chances to win the lottery prize. Not 1. Even though the odds of winning per ticket remains unchanged.
2 disks buy you 2 tickets in The-Drive-Failure lottery.
Back in the 90's, BT (British Telecom) had a 80+ node OPS cluster build with Pyramid MPP hardware. They had a dedicated store of scsi disks for replacing failed disks - as there were disk failure fairly often due to the number of disks. (a Pryamid MPP chassis looked like a Xmas tree with all the scsi drive LEDs, and BT had several)
In my experience - one should rather expect a drive failure sooner, than later. And have some kind of contingency plan in place to recover from the failure.
The use of symbolic links instead of striping the filesystem protects from the complete loss of the enchilada if a volume member fails, but it does not reduce the risk of loosing data.
I would rather buy a single ticket for the drive failure lottery for a root drive, than 2 tickets in this case. And using symbolic links to "offload" non-critical files to the 2nd drive means that its lottery ticket prize is not a non-bootable server due to a toasted root drive.
