Reading unicode file using pure C++??

Hi Guys,
I need help reading a unicode/utf8 file using C/C++. Any pointers or sample code will be of great help.
Thanks
Gulshan

See sections 20.2 and 20.3 of "The C++ Programming Language" 3rd ed. - by Bjarne Stroutrup.
I'll go out on a limb and naively state that using wstring rather than string will take you a long way towards solving your problem, but you might have to play around with char_traits. The general usage of wstring should be identical to string, so I'm sure you can find many examples.

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..

Reading unicode files

I have a problem reading unicode text files.
As written in books and that stuff i should use Reader instead of InputStream for this purpose. I do so and what i get is letters separated by \u0000 chars. So what is the way to convert unicode to "normal" strings. I deleted all the 00 using StringBuffer, but it don't work in older VMs, such as provided with win98.
So, what is the way-out?....the second problem going to be is writing unicode files:)

You have a file encoded using UTF-16, it sounds like. If you use a FileReader, let's say, that object will assume the file you are reading is encoded in your system's default encoding. Unfortunately that default is not going to be UTF-16, but something else like ISO-8859-1. To read a file using an encoding that you specify, do this:Reader r = new InputStreamReader(new FileInputStream(yourFile), "UTF16-BE");This will give you a reader that will probably work... although I don't know if your files are "big-endian" or "little-endian", so you might have to use "UTF16-LE" instead.
You can wrap that Reader in a BufferedReader if you like, that's generally more efficient for input processing. And to write your data in UTF-16, do the similar thing using an OutputStreamWriter with the same encoding. Check out the API documentation page for the java.io package; the line about InputStreamReader will have a link for either "encoding" or "charset" that will give you more information about UTF-16 and so on.

Reading XML file using BAPI I must use adapters .

Reading XML file using BAPI and then uploading that xml file data into SAP using BDC.
I cant take file on to my Application server I am getting the file dynamically from other file server and I need to use BAPis to read data from XML file.please tell me what should be my Import,Export and Tables parameterrs should be.
Thanks

Hi,
Import, export and table parameters for BAPI is required, without that BAPI will not able to collect the data from XML. What you need to do is write a Zprogram and collect the data, store that data in internal table and call the BAPI by passing required parameters.
Different Scanarios:
1) Before calling a BAPI write some other program which collects the data from XML and create a UNIX file. Try to get the data from UNIX FILE
2) If you see the XML tags, data will be in side that tags, try to get the data from XML tags and store that data in one SAP table. You can use the BAPI by fetching the data from table
3)Create a table and store the data in the table. Use the table in SAP to extract the data.
BAPI won't work without any parameters, you have to pass some parameters then the BAPI will return some values.
Hope i am clear.
Thanks&Regards,

How to read HTML files using UTL_FILE

Hello Friends,
How to read HTML files using UTL_FILE package ? According
to Oracle documentation UTL_FILE can read or write OS Text Files.
Thanx in advance..
Adi

HI Hareesh,
i have gone through that blog.
i tried it...but i am getting mapping error no receiver determination fond because there are so many excel files.
my data is available on sharedString.xml but also it is in not same order.
i have no clue how to handle this part form the blog.
"This way our mapping will receive all data from the sheet in an XML format. The only thing that's left is to create an XSD file from the XML file we received in order to be able to use it in the mapping and as our Service Interface and we can proceed with mapping. As you can see from the sheet.xml files all the data is placed with column name and row number so it's not that difficult to map it to an table type format using the Message Mapping only (no java, abap mapping required)."

Is it possible to read the file using File Adapter which is in client machi

Is it possible to read the file using file Adapter which is in client machine(on the same network).Then what is thee need of FTP Adapter?

You can achieve that by exposing your client machine as a drive, then you can go using file adapter.
FTP adapter will help you to communicate with different machine which is in different network.
It is considered good etiquette to reward answerers with points (as "helpful" - 5 pts - or "correct" - 10pts).
Thanks,
Vijay

How to read 835 files using ssis

Hello Everyone,
It is possible read 835 files using ssis.
Please share your suggestions on this.
Regards,
Vaishu

Hi Vaishu,
None of the canned (standard) SSIS tasks let you do so.
But if you can buy http://www.cozyroc.com/ssis/edi-source (I am not anyhow affiliated with CozyRoc) it states it can read ERA (AKA 835) files. CozyRoc lets you run it for free in Dev.
If there will be a decision not to buy then you can simply crate a transformation out of several manipulations or by creating a custom SSIS component or some other programming methods need to be used.
PS: Again, I just know CozyRoc quality of components is awesome, but I do not make any profit from referring to it.

I am unable to read pdf files using Acrobat Reader on my MAC OS X. Any suggestions?

How do I read pdf files using my MAC OS X?

You can read pdf files with preview. Select a pdf document, right click on it, and choose Preview. You can also get info and select to choose Preview for all.
You can also install Adobe Reader 10.1.3 for Lion. It will also install a plug-in to read pdf docs in the browser.

How to create and read text file using LabVIEW 7.1 PDA module?

How to create and read text file using LabVIEW 7.1 PDA module? I can not create a text file and read it.
I attach my code here.

File_IO.vi ‏82 KB

Well my acquisition code runs perfect. The problem is reading it. I can't seem to read my data no matter what I do. My data gets saved as a string using the array to string vi but I've read that the string to array vi (which I need to convert back to array to read my data) does not work on the pda. I'm using version 8.0. So I was trying to modify the program posted in this discussion so that it would save data from my DAQ. I did that but I still can't read the data after its saved. I really don't know what else to do. All I need to do is read the data on the pda itself. I can't understand why I'm having such a hard time doing that. I found a possible solution on another discussion that talks about parsing the strings because of the bug in the "string to array" vi. However, that lead me to another problem because for some reason, the array indicators or graphs don't function on the pda. When i build the program to the pda or emulator, the array indicators are faded out on the front panel as if the function is not valid. Does this kind of help give a better picture of what I'm trying to do. Simply read data back. Thanks.

To read text file using utl_file

I would like to read test_file_out.txt which is in c:\temp folder.
create or replace create or replace directory dir_temp as 'c:\temp';
grant read, write on directory dir_temp to system;
then when i execute the below code i get the error .
// to read text file using utl_file
DECLARE
FileIn UTL_FILE.FILE_TYPE;
v_sql VARCHAR2 (1000);
BEGIN
FileIn := UTL_FILE.FOPEN ('DIR_TEMP', 'test_file_out.txt', 'R');
UTL_FILE.PUT_LINE (FileIn, v_sql);
dbms_output.put_line(v_sql);
UTL_FILE.FCLOSE (FileIn);
END;
ERROR:
invalid file operation
i would like to use ult_file only and also can you let me know to read the text file and place its contents in tmp_emp table?

Are you trying to read the contents of the file into the local variable? Or write the contents of the local variable to the file?
Your text talks about reading the file. And you open the file in read mode. But then you call the UTL_FILE.PUT_LINE method which, as SomeoneElse points out, attempts to write data to the file. Since the file is open in read-only mode, you cannot write to the file.
If the goal is really to read from the file, replace the UTL_FILE.PUT_LINE calls with UTL_FILE.GET_LINE. If the goal is really to write to the file, you'll need to open the file in write mode ('W' rather than 'R' in the FOPEN call).
