Writing text file in while loop

Here is my question about writing text data to a file in a while loop...worded best I can.
I have an Init case where I have the user choose a file path and name. I take the ref out and then I have data that is being written to the file. The loop will take 40,000 pieces of data write them to the file and go back to the get data case to collect another 40,000 data points. But when I open the file, I only get a file as big as 430KB. I'm not sure but can somone show me an example of pulling analog data from a DAQ Assist, doing a calculatoin on it, writing it to a file and repeating that by adding it to the same file at the end of the previous data?

Take a look at the attached VI's. Did you have your data set to append? This could be your problem.

Error in writing to file encountered while applying patch 9.2.0.8

Hi,
I encountered the error message below while applying Oracle 9.2.0.8 patch set using OUI on server running Oracle 9.2.0.7 and Windows 2003 Enterprise Edition SP2:
Error in writing to file 'C:\oracle\ora92\BIN\orapls9.dll'
[C:\oracle\ora92\BIN\orapls9.dll (he process cannot access
the file because it is being used by another process)]
I've already stopped the Oracle instance and services before invoking the setup.exe.
My question is: Why this is happening and what is the resolution to prevent this error from happening?

I used the script in the Metalink note 454040.1 and chose 5. I typed in the orapls9.dll to see which module is locking this dll and I found out it is avrrepsvc.exe which is one of the services our application is running. I just stopped it in Services Console and run the setup.exe of the patch. The installaton of patch run successfully. I checked the version using 'select banner from v$version' and I now got this results:

Problems with opening file with while loop

Greetings everyone,
This is probably a quick question, but I am familiarizing myself how to open data files in Labview. The attached code works if you enter a file from the folder button on the front panel. However, if the path is blank and you hit the run (arrow) button, a dialog box comes up and asks for the file.
I select the file, but the dialog box keeps coming up. I think this has something to do with my while loop. Can anyone tell me where I am going wrong?
Thanks!

TheLT,
1. crossrulz was right. The Read FromSpreadsheet File.vi opens and closes the file each time it is called. If no file path is present at the input when it is called, it will pop up a file dialog.
2. LabVIEW uses a dataflow paradigm. In your program the effect of this is that the File path control is read almost immediately when the program is started and never again after that. So, if the program is already running when the file is selected in that control, the new value is never read and the value (empty) in the control when the rpogram started is used.
3. The fix is to use an event structure with a file path Value Changed event to detect when the control has a value entered and then read the file.
4. Sequence structures obscure code, make it difficult to modify and extend code, and can almost always be eliminated by effective use of dataflow. Local variables should not be used just to pass data around. Wire is always the best way when possible. In your program adding a few wires allows elimination of the sequence structure and the local variables.
5. Your graph loop should have some kind of delay or wait. No need for it to run as fast as the processor will allow - and to hog all the CPU time - to repeatedly put the same data onto the graph. This is another place where an event structure is appropriate. Only update the graph when the X-Axis or Y-Axis selections have changed. Note: Accepted best practice is to use only one event structure in a program, although there are a few advanced cases where multiple event structures are appropriate. You only need one.
6. If the slected file does not contain the "endheader" string, the program will never stop. Add a test for EOF to stop the program if the End of File is reached without finding the flag.

Open/close file in while loop

VI reads 3 temperature sensors connected to RS232 port ( external rs232/RS485 converter , sensors have different addresses). When VI starts , user is asked to chose location and filename of data log file for each sensor ( write to the same file or to new file).
3 START/STOP buttons controls data logging from sensors. Right now it just starts or stops data reading from sensor and writing to file. What I would like to have is that user is asked to enter file name and location not when wole VI starts, but when he START/STOP button is pressed. ( When user press button 1, he is asked to enter file name and location. When data logging from that sensor is stopped, file is closed. When data logging is started again, user again must select data log file). The same for START/STOP buttons 2 and 3.

Hello.
The short answer is that you have to put the "Open/Create/Replace File.vi" inside the case stucture, so that that executes each time a button is pressed. You should also be closing the files after you write to them, which I did not see you doing in your VI.
I am attaching a modified version of your VI which should perform what I understand you want. I am using the "Write Characters To File.vi" which is an easy top level VI for writing data to files, which opens, writes and closes the file each time it is executed.
I also removed the local variables and used the boolean buttons directly inside the sequence structure. In general, you should avoid the use of local variables unless it is absolutely necessary.
Hope this helps.

Problem writing condition of a while loop

I'm receiving an error when attempting to compile my class.
while(numItems != 1 || 2 || 3) (numItems is an integer variable)
Basically, using the Scanner class, I request an integer input from the user, and that input needs to be either 1, 2 or 3, so I have included the while loop as a validation tool, so that whenever the user's input is NOT 1 or 2 or 3, the system prints out an error message and the user has to reenter. However, the code above is highlighted when I compile, and the error description states that I cannot use the || operator for the int data type. I wasn't sure if the OR operator was two || pipes or one, but I receive the same error regardless.
Is there a way around this?
Thank you.

In conjunction with Encephalopathic's syntax question for your valid boolean expression, you'll also have to replace the || operators with the && operators to achieve your described condition.

Writing thermocouple data to measurement file from while loop

Hello,
I'm trying to write thermocouple data that has already been filtered into a measurement file. My code works, but has many zero-time entries (probably from the filtering aspect), and some of the non-zero-time entries are even out of sequence (my output file is attached as well as my VI.) I'd love any help regarding getting this to work!
Thanks in advance,
Megan

Hi Megan,
do you really need to sample thermocouple data at 1kHz? How fast does the temperature change - and how fast do thermocouples react on that temp change? (Which sample rate is recommended for your hardware?)
Are your filter settings reasonable? "TC2 unfiltered" looks quite ok, while the "filtered" graph looks awful (atleast for a TC measurement)…
And you should definitely fetch a constant number of samples from DAQmxRead. Usually you read 1/10th of the sample rate, so reading 100 samples for 1kHz sample rate!

Loop text in a while loop , from a db . Please help

am new to java and woundering if some one could just correct this problem am having or point be in the right direction to fixing it.
am connected to a database and want to show the reults in a Jframe. but if i place the code in a JLable or textpanel the text is all grouped together and does not line break.
works line if i just System.out.println the table results but i need it to be in a Jframe
here the code below:
while ( rs.next() ) // this will step through our data row-by-row

Thanks for your time
chris mon

Thanks very much for the reply and for the help:-). You're welcome.
so the value is the StringBuilder(100), is that like
how many characters it can hold?Read the API for that constructor. 100 is just an initial capacity before resizing will occur. If you add 80 characters, no resizing will occur. If you had 1000 characters, it will resize to hold it. The upper limit is determined by memory (and by length of an array being an 'int', I guess). Anyway, I'm sure you can hold whatever you need to hold.
can i ask one more helpful tip aswell. when it
outputs the results they are all together like

Writing Text Files in Java

hello!
i am creating an Applet game and I would like to create Rankings.
So, i need to take data from java and transfer them into HTML. At my
university's book says that everytime we open a file to write in it, if there are
already data, Java removes them and then writes the new ones. But I want
a static file where Java can write the updated rankings and HTML can take
them and use them in site. Is there any way to achive that guys?
If i wasn't clear, i just want a way to make Java not to delete any data in a file
everytime it needs to write something in it!
thanks alot!

thanks alot!There are a number of problems here.
First of all you can always append to a file, but that's not actually what you want to do.
Second you can read the whole file in, find the values you want, change them and write the whole file back. This is more of what you want to do but HTML is not the best choice for doing this.
But the most fundamental problem is that you do not write to files of any kind in an Applet.

Yap the row and column will change but i had already parse these lines into my code. However, i am still figuring on how to get the integer number 1,2,2,4 of the text file using while loop and not include the "</matrix>" in the reading. Can this be done?If the numbers you want are at fixed byte positions in the file that are known ahead of time, you can use java.io.RandomAccessFile to skip to those positions. However, that seems unlikely.
If, as is the more likely case, those are not at fixed positions, you'll have to read everything preceding them. (Note that this is not a Java issue. This is how file I/O works.) You'll need to ignore the lines that are meaningless to you (read those lines and do nothing with them) figure out, by whatever rules you have--line numbers, preceding tokens, whatever--when you're at the lines you do care about, and then read and process those lines accordingly.

Writing plain-text files in UTF-8 encoding under MacOSX

Hello forums,
I've run into some problem writing text-files under MacOSX. I've tried several methods of writing, the current one I'm using is as follows;
private void stringToFile(File file, String string) throws IOException
    OutputStream fout = new FileOutputStream(file);
    OutputStream bout = new BufferedOutputStream(fout);
    OutputStreamWriter out = new OutputStreamWriter(bout, "UTF-8");
    out.write(string);
    out.close();
}However, when I open the file letters other than A-Z appear corrupted in Text-Edit, though in BBEdit the file is identified as UTF-8 without BOM. (still corrupt.)
The application uses some components I am not so familiar with, which makes trouble-shooting less of a breeze.
It is a spring-framework web-app, and the string to be written is passed to the application through a HTTPClient.
The string itself is constructed by
MultipartFile content = multipartRequest.getFile(CONTENT_PARAM_NAME);
String contentStr = (content != null) ? new String(content.getBytes(), "UTF-8") : null;and is created client-side by
new FilePart("content", new ByteArrayPartSource("content", strContent.getBytes()), "", "UTF-8")I would appreciate any clues you have hinting towards a solution.
I have tried to isolate parts by f.ex. writing a fixed string (which still would not work properly, which leads me to think that the HTTPClient/Spring part is not to blaim).
Message was edited by:
joakim.back

Good idea,
I'm now ensuring that the hashcode of the clientside and serverside String match, supply the bytes as UTF-8, and write it properly with
private void stringToFile(File file, String string) throws IOException
    BufferedWriter out = new BufferedWriter(
                new OutputStreamWriter(
                            new FileOutputStream(file), "UTF8"));
    out.write(string);
    out.close();
}I adjusted the stringToFile earlier, so I'm not sure wether the old code still works.
TextEdit under MacOSX still view the files as corrupt, but BBEdit and EditPlus under windows view the result fine.
Lessons learned? Beeing very careful about identifying sub-tasks and dealing with them separately.
..ofcourse, my job is not done since the damned applescripts dealing with the output treats the files as TextEdit do, but that's a task for tomorrow.
Thank you for your assistance!

Writing a file for prescribed amount of time in a while loop after the triggering condition is met

Hello Guys,
I am trying to program an application in which if the trigger condition is met it should start to write the file.
I was able to do that, but if I want it to be written for certain amount of time, and once the trigger condition is met, it should continue to write the files for prescribed amount of time. I was not able to do this. The file name should also be updated accordingly.
I tried to with some options by keeping the creation of the file outside of the loop, if I do that then if the trigger condition is not met it will stop writing and I dont want that, as once the trigger condition is met it should be true thereafter.
So I cant keep any thing outside the while loop, bcaz then it checks the condition of the shift register for the trigger and I have it as a false constant.
I am attaching my application which is kind of mess and I have written in the application where I am having problems. For every iteration of while loop it makes a new file, and i dont want that, I want to write specific amount of time data to the each file.
Please take a look at my code and help me in solving the problem. Any insights and examples on how to do this thing will be a relief to me.
Thanks in advance.
Regards,
Nitin

Is there any way to format a text file while writing it in java ?

Heyya Fellas,
I am working on a project and at the end of the process, the project should generate a report file in .txt format in the location prescribed by user. I am able to generate it and do all the processing but can i the report in a more presentable way. Like is there any method in java code so that we can make the text in the report file appear bold or italic while writing a file in java in runtime?
Please help me.. any gist or click will be a favor.
Thanks and Cheers

If you are producing csv, then html style markup is a definate candidate, if you are producing reports than look into iText for creating pdf documents.I beleive dats it..
Actually i am hitting a JSP's URL and it inturn calls a servlet and then the process takes place..

The files are generated and every thig is working fine but i wanted to add that extra bit of a gloss to report.

How do I store 4 hours of data and get it out of the "while loop" into a spreadsheet file for documenting purposes? "See additional Text for additonal info"

What a have is a VI that uses the following SUbvi's, starts with FP OpenVI, then FP Create TagVI, into a "While Loop" which contains a FP ReadVI outputting data into a Index ArrayVI outputting to a Display (DBL). This shows the output of a FP-AI-100 monitoring a 9v battery. I have to monitor this battery for a 4 hour period my problem is storing the 4 hours of data and getting it out of the "while loop" into a "Write to Spreadsheet File VI" all I seem to accomplish is just one data sample which I get into a spreed ship file with no problem. I just can't get 4 hours worth. By the way this is my first VI and I'm self
trained so have mercy.

I figured it out thanks.
