Looks like you're creating a new file (which overwrites the old one) every time. You need to open the file first and then append to it.

How to add data in xml file

Hi ALL
I want to add new fields on seeded EBS page to store their values in hr_api_transaction table whoch contain information of other fields on that page which are seeded
but that table has one column which stores xml file and that xml file has all information about that page's fields
how can I store my custom fields values in that xml file ?

Hi,
As Andy said, add data to an xml file is overwriting, if you mean append data to xml file, please look this article:
http://codesamplez.com/programming/linq-to-xml-tutorial, Since this issue is more related to ASP.net, you could also ask this issue in asp.net forum:

With an API like Xerces you can parse an XML document into a DOM tree. You can do modifications on that tree manually and then write it back out as XML data.

How to read data from a file that was formatted by excel?

How to output data to a file in SCC-SG04?

I am using SCC-2345 with SCC-SG04 connected to NI-6221 in Windows 2000 in VC6.
How to output data to a file like data1.dat in VC6 or in Labwindows/CVI?

Hello mwibm,
If you just want to do file input/output in LabWindows/CVI, I would take a look at the Formatting and I/O CVI library or the ANSI File I/O functions. For example, if you just want to write an array of data to a file, I would look at the ArrayToFile function or the fwrite/fputs/fprintf ANSI C functions included in stdio.h. The ANSI C functions will also work in Visual Studio. More information on the LabWindows/CVI File I/O functions can be found in CVI help, and more information on ANSI C functions can be found in CVI Help and online at various websites.
Maybe you could further clarify what problems you are having and what kind of data you want to write to a file.
Thanks.

Don't use both. Things like a dsn are best defined in the
onApplicationStart method of an application.cfc.

How to insert data from *.dmp file to oracle 11g using Oracle SQL Develope

hi
i backup my database using PL/SQL developer and made *.dmp file
how to insert data from *.dmp file to oracle 11g using Oracle SQL Developer 2.1.1.64
and how to make *.dmp file from sql*plus ?
thanks in advance

Pl/Sql developer has a config window, there you choose the exec to do the import/export.
Find it and his home version, it may be exp or expdp, the home version is the version of the client where the exp executable is.
Then use the same version of imp or impdp to execute the import, you do not need to use Oracle SQL Developer 2.1.1.64. If you want to use it, you must have the same version in the oracle home that exp/imp of sql developer use.
