     }This code is to read a text file. But there is no such thing that will convert your text file to xml file. You have to have a defined XML format. Then you can read your data from text files and insert them inside your xml text. Or you may like to read xml tags from text files and insert your own data. The file format of .txt and .xml is far too different.

How to read a .pdb file using J2ME

hi all,
I am using J2ME to write a program that need to read a .pdb file.
The .pdb file was generated by other application.
The .pdb file could not be open using J2ME's RecordStore class.
How can I open the .pdb file using RecordStore or use other approach?

You'll need the FileConnection api in JSR-75. Note that your device needs to support this! And no, there is no code to read the file format. You'll need to do that yoursels.

How to read the excel file using webdynpro abap?

Hi,
how to read and modify excel file using webdynpro abap?
Regards,
Pavani

For reading excel file follow the steps :
1. Use a File upload UI element and bind it with xstring.
2. Now your excel will be uploaded and stored in Xstring.
3. Convert Xstring to String data using FM 'HR_KR_XSTRING_TO_STRING'.
4. Now split the string at new line so as to make an internal table .
Ex . SPLIT l_string AT cl_abap_char_utilities=>newline INTO TABLE it_table.
here it_table is type table of string.
5.now loop at the internal table and separate the content of this table separated by tab.
Ex. SPLIT wa_table AT cl_abap_char_utilities=>horizontal_tab INTO TABLE it_new.
it_new type string_table.
6. For more info , refer this thread :

How to read and write files using flex?

Using flex, we would like to make some utility that will do a
lot of reading and writing from local files.
The writing is what I am more worried about. How is this
possible?
I want to make .zip files containing many xml files, and some
assorted media files such as .swf jpeg, html, etc.
I am new to flex btw, I've never used it properly before, and
this is the main concern I have with flex, which is that it doesn't
let me write and read lots of files.
Mainly we are looking for a good cross platform solution that
will let us develop an app, and flex looks professional and it is
cross platform. The "internet app" side of things, isn't so much
what we need really.
Would wxWidgets be better suited to our needs?

The Flash player sand box will not allow reading and writing
local files. If you want to use Flex to create a desktop you will
need the Apollo runtime. The alpha is available at Adobe
Labs.

How to Read a CSV file using pure PL/SQL

Hi friends - Is there a possibility to read a .TXT/CSV file from a local machine and display the contents on the form fields each record at one time.
The logic to flow through the records can be build, but the problem is where to begin from to start reading the file using PL/SQL. I don't want to use any third party component/API as such. Is there any way in forms by using PL/SQL to read an external CSV file and interpret the contents.
I have read about SQL * Loader on some sites but cannot find any way to invoke it on windows platform. There seems to be UNIX commands to invoke the .CTL file that is used by SQL Loader. Any help is much apreciated.
Rgds

Hi Thanks for your replies, TEXT_IO seems to be a solution but not very comprehensive as it provides limited exposed functions to perform complex operations while read and write of files.
I think SQL*Loader is a valid solution, but as I stated in my original quote Im not able to invoke it from the command prompt. The command that is shown on the suggested URL(http://www.orafaq.com/faqloadr.htm) is not found on my machine. I have Windows 2K installed. Is there a seperate patch or a download available from where I can get that .EXE to invoke the utility.
Thanks..

How to read from pdf file using VB

I have a PDF file which contains three columns, emp no, designation, contact_info. I have 10 rows in that pdf file. I want to read row by row from the pdf file and write into another text file(tab delimited) using VB.
Could you please help me reading the pdf file?
Thanks,
Arindam

Without reading it in detail, this seems to be automating a save as text function in Acrobat. This will not give you any position information.
If you want position information without writing a plug-in, you need to use the getPageNthWord and getPageNthWordQuads methods in JavaScript.
If you have not already done so, you will need to download the Acrobat SDK which has the documentation you need.
Writing in C# makes even very simple things complicated; if you have a choice, consider VB.

How to read a local file using as3 in a flash object in HTML? [urgent]

My web site contains a flash object.
I want to use as3 to read some local .txt file
by getting the user directory of the file.
i know AIR can support this by sth like:
File.desktopDirectory.resolvePath
but when i open a AIR file for this, it seems
the action cant be run when i embed it in html.
And i tried to use the above function in a normal
flash file in the action script.
But it cant recognize the File. class..
How can it be done ?
It's reli urgent,
please help...
Thanks !

a web based flash app can't detect user directories. you can use the filereference class'es browse method to let the user locate a file in any directory the user wants. flash can then retrieve the file's name and type. but, as mentioned before, flash can't determine the file's directory.

How to read a XML file from BLOB column and insert in a table - PL/SQL Only

Hi,
To make data load more simple to end user instead placing file on the server and use SQL-LOADER, I came up with new idea that using oracle ebusiness suite attachment functionality. that loads a XML file from local PC to a database column(table is fnd_attachments, default data type is BLOB over here).
I tried with DBMS_LOB and didnt get around.
Please can anyone tell me how to read the BLOB column using PL/SQL and store the data in a oracle table. Here's the sample XML file and table structure FYI.

Read an avi file using "Read from binary file" vi

My question is how to read an avi file using "Read from binary file" vi .
My objective is to create a series of small avi files by using IMAQ AVI write frame with mpeg-4 codec of 2 second long (so 40 frames in each file with 20 fps ) and then send them one by one so as to create a stream of video. The image are grabbed from USB camera. If I read those frames using IMAQ AVI read frame then compression advantage would be lost so I want to read the whole file itself.
I read the avi file using "Read from binary file" with unsigned 8 bit data format and then sent to remote end and save it and then display it, however it didnt work. I later found that if I read an image file using "Read from binary file" with unsigned 8 bit data format and save it in local computer itself , the format would be changed and it would be unrecognizable. Am I doing wrong by reading the file in unsined 8 bit integer format or should I have used any other data types.
I am using Labview 8.5 and Labview vision development module and vision acquisition module 8.5
Your help would be highly appreciated.
Thank you.
Solved!

read avi file in other data format.JPG ‏26 KB

Hello,
Check out the (full) help message for "write to binary file"
The "prepend array or string size" input defaults to true, so in your example the data written to the file will have array size information added at the beginning and your output file will be (four bytes) longer than your input file. Wire a False constant to "prepend array or string size" to prevent this happening.
