Writing data in a File

When I got my output into a file each line has "OD" at the end . What is this ? and How can I fix it?
Thank you!!!

When you are writing in a file, which stream are you using? Character stream or byte stream? And after that, are you using the formatter class to format the output. Please give details.

Problem while writing data on xls file using jxl API

Hi,
I am getting problem while writing data on excel file using jxl api.
When i write data on file and all handles associated to the file are closed, file size increases but when i open the file nothing is written in it and when file is closed manually from excel window, file size decreased to its original that was before writing data.
here is code:
          FileOutputStream os = new FileOutputStream(this.dirPath + this.fileName, true);
          WritableWorkbook this.workbook = Workbook.createWorkbook(os);
after writing data following handler are closed:
this.os.flush();
                    this.workbook.write();
                    this.workbook.close();
                    this.os.close();
                    this.os = null;
can any body help me.
Thanks in advance

Err, I did help you. I did understand your problem; and I solved it for you. What was missing was that you apparently made no effort to understand what you were being told. Or even consider it. You just argued about it, as though you were the one with the solution, instead of the one whose code didn't work.
And the other thing that was missing was the part where you said 'thank you' to me for solving your problem. Somewhat more appropriate than biting the hand that fed you, frankly. I do this for nothing, on my own gas, and it's extremely irritating when people keep asking about problems I have already solved for them. I am entitled to discourage that. It's part of making them more efficient actually.
But it happens often enough that it also makes me think I'm just wasting my time. Probably I am.

This won't work. First, like i said, File class is not for accessing remote files, it is only for local files.
Second, Workbook class is a class from Java Excel API. He is not working with xls. Anyway that wouldn't work either.

Writing Data to Multiple Files

Hi,
I got a problem while writing the data to multiple files.
Actually my requirement is,
I want to read the data from multiple files and retrieve the required data from those and save that data into separate files.
Meaning if i read the data from "D:\kiran\kk\123\kiran.txt" the retrieved data should be saved in "D:\kiran\kk\kiran.txt" the file name should be created with the input file name.
here is my code,
//here i am taking the files into loop
for(int i=0;i<files.length;i++){
try{
//reading the files
BufferedReader br=new BufferedReader(new FileReader(files));
//creating a new file for writing the retrieved data
pw=new PrintWriter("D:\\Kiran\\kk"+File.separator.concat(str[i]));
String line=br.readLine();
while(line!=null){
line=br.readLine();
//here i am matching the required data
Matcher m = Pattern.compile("name(\\s*\\W*\\w*\\W*.\\w*.)|invoice (\\W*(\\d+))|amount(\\W*(\\d+),\\d*)|site(\\s*Rs\\.[\\d]*,[\\d]*/-)", Pattern.CASE_INSENSITIVE).matcher(line);
while(m.find()){
System.out.println(m.group());
//here printing the retrieved data to a file
pw.println(m.group());
br.close();
but i am ending up with some issues.
Data is reading properly from all the files, but when i write that data into individual files the data which is retrieved from last file is only printing into the file which is created last.
Please help me regarding this,
Thanks,
Kiran

D:\kiran\kk\123\
In this folder some files are there say,
kk.txt,kiran.txt,praveen.txt and so on, i can read the entire data from those files and also retrieving the required data like name,data etc. from all the files. Now the retrieved data should be stored in individual files means, if the data is retrieved from kk.txt then that particular data should be stored in the file with the same file name but in different location likewise it should happen for all the files those are in that folder.
Thanks,
Kiran

If you write data to a file, simply don't include any blank lines. We cannot give more specific advice unless you are telling us how you are writing. Are you writing to a new file or appending to an existing file. If the blank lines already exist, you need to read the entire file, remove the undesired lines from the string, and write the data back.
Notepad files don't have any "corners". Please describe what you are trying to do.

By a sub VI, Writing data countinously to file by a ''Write' button in Main VI??

Good morning...day to all !
I've made a program, where I'm reading data generated by a device connected to a com port. These data are red from the port to an indicator buffer and then, into a file when a button, " write file" are pressed. I've placed the 'WriteDataToFile.VI' in a Sub VI placed in Main VI.
When my Main Program starts and I switch a start button, a file dialog box opens, so I can choose an existing file or a new file to write data to!
I want to Make a Button named " Write file" so when pressed , the Dialog box opens and I can choose a file to write to.
In that way I can avoid the Self pop up dialog box.
I've spended the hole weekend trying doing that, but no succes. The biggist problem by that is:
To write a continously to a file I also need to continously read the data from the port, And because of that, I got to write the data to a file as quickly as possible when Red from the port. So I gotta put the WriteDataToFile.VI 'sub', in the ReadData:vi 'Sub'. By that I always get the Dialog box poped up, by each while loop iteration. Just because the Software to the open Dialog Box (Write file), is placed in the ReadDataVI, Sub.
Please Help me with that Guys , girls, any one, also peoble from Mars To!
Attachements !!

ReadDataWriteToFile.vi ‏62 KB

Hi Zamzam,
I think the point you should work on is the architecture of your whole application, LabVIEW has very well designed templates.
If you go to new >> new... >> vi from template >> frameworks >> design pattern >> user interface event handler
It is a very robust architecture with which you can draw cases for (almost) any kind of event such as a click on a button.
in your application, you could choose the file to write on the first run, then put the file refnum in a shift register and add an event case handled by the "write to file" button that writes the acquired datas.
You could even go further and set that "wite fo file" case on other event, for instance new data from the port com.
wooopps... I tried to be as clear as I could but english is not my natural language , so please tell me you need some more help
When my feet touch the ground each morning the devil thinks "bloody hell... He's up again!"

Writing data in text file..

1. check the file name in D:\\temp\\test.txt
2. if it exists, then open file. if there is data, then read data. after the last record, it writes new data.
3. if it does not exist, create text.txt file and write data into text.txt file.
so far, I have a code..
import java.io.*;
import java.util.*;
public class Main {
public static void main(String[] args) {
String filename="test";
String format = "%1$-9s%2$-3s%3$-30s%4$-30s%5$-30s\n";
String arraydata[] = { "John", "F.", "Kennedy", " ", "t", "John2", "F2.", "Kennedy2", " ", "t2"};
String cnt_id ="2";
int cnt_orderid = Integer.valueOf(cnt_id);
try
PrintStream ps = new PrintStream(new FileOutputStream("D:\\temp\\"+filename+".txt"));
for (int i=1; i<cnt_orderid; i++)
ps.println(String.format(format, (Object[])arraydata)); // write in test.txt file
ps.close();
catch (Exception e)
System.out.println(e);
my question is..
1. how to check the file exists or not
2. how to write the data in the new line after the last data in the file.

1. Use a File object.
File file = new File("someFile.txt");
if (file.exists()) { ... }2. Consider using FileWriter; the constructor allows you to append to the end of the file:
FileWriter fileWriter = new FileWriter(file, true);Michael

Writing data to log file

Is it possible to write data to a log (text) file from within Crystal Reports, possibly in a UFL? Is there a way that's already built in to CR?
Thanks.
Ron

Ido - thanks for the link. This will help.
Don,
Not exporting a report to a text file. More like logging report events. One of my report developers was thinking of maybe tracking the start/stop times of each publication per person as well as the full run time.
I hope I explained that correctly.
Thanks.

Somebody experience with writing data in Access file?

I want to write my data in a Access file.
Is it true, that I have to create a macro in the Access-file?
I have no experience with macros. Can somebody tell me how I can do that?
Has somebody an example?
Thanks for help.

No, you don't have to write a macro. I guess you're refering to the shipping example that uses DDE. Instead of DDE, you can use ActiveX. There have been several examples posted to the forum that use this to read and write from an Access database. There is also the Database Connectivity Toolkit from NI that uses ODBC/ADO/SQL to talk to any database.

Hi Mehul,

Streaming data and writing data to measurement file problem

Hi everyone,
I found something wrong about my code but i don't know exactly what it is first i have a program for acquiring 15 analog signals(NI PXI6259) after acquiring the data i use network stream to stream data from my NI PXI8186 to the host pc these steps are in target VI, after streaming data to host PC
, i tried to write down the data to the spreadsheet using Express write to measurement VI.
Problems : 1. After i run the host Vi and target Vi the number available to read is always 0 after sometimes the data displaying on the chart incdicator on host Vi is stopped and start counting the numberavailable to read also the time indicated on X axis of the chart doesn't grow.

Dear Crossrulz
Thank you for your prompt reply i have removed the input to "Samples Per Channel" on the DAQmx Timing VI already but still didn't arrange the
channels input i will do it but i want to keep it this way first. Now the data acquiring looks okay but i have found new problem.
After running the program for acquiring the data for about 5 to 6 minutes the program will stop acquiring the data or
sometimes the target (NI pxi8186) will reboot itself and displaying message "Reboot due to system error" "System state: Safe Mode (System error)
and on the Host PC there will be a window pop-up displaying
"Waiting for the target (NI-PXI8186-2F0a597C) to respond" "Stop Waiting and Disconnect"
i didn't run the host Vi just run the target Vi only. If this problem caused from the program or the hardware ? Please help.

Error writing data in a flat file using UTL_FILE feature

Hi All,
I have written a package which fetches data from four different cursors and inserts into a temporary table.
Now this temporary table is used to write data in a file using the UTL_FILE feature.
fhandler :=
UTL_FILE.fopen (l_path,'Demand_Transactions_'
|| TO_CHAR (SYSDATE, 'YYYYMMDDHH24MI')
|| '.txt',
'w',
max_linesize => 32767
This table has 62593 records and when it starts writing data into the file from the table it errors out after writing 30045 records with the error - ORA-01722: invalid number.
Can anyome please advise me is it because of the max_linesize => 32767. If not then what can be the possible reason.
Any help in this would be highly appreciated.

The error would indicate that you have a character to number conversion going on somewhere but the characters are not numeric so it's failing that conversion.
This doesn't sound like a UTL_FILE issue, but more to do with how you are building up your strings to output to the file.
You would need to show us your code that builds up the lines you are writing out, with details of the datatypes of any of the columns/variables included in that.

Writing data to New Line in a File

Hi guys,
Im writing data to a file, i want to write data on different lines, not contineously.
My code is writing the data but not the next line.
Please Help. My code is below :
fw = new FileWriter(filename,append);
fw.write(cur_timestamp().toString());
fw.write("\n");
error_data = errorCode + " " + msg;
fw.write(error_data.toString());//appends the string to the file
fw.write("\n");Thanks
Rebekah

You'd still want to use the System property, because other editors might display it correctly, but for the Windows platform, it's acctually incorrect behavior. The separator would be "\r\n". I think on a Mac, it'd be "\r" - so your program would fail again there.
