Write a comment to a file

I achive a signal and I want to save it on a file.
I want to insert a comment when I want during VI running and not to stop VI change comment and restart.
I find this method in the file attached but I want to do other thing:
1- Change the file when I write a comment
2- Name the new file with the comment string
3- don't use a button from FRONT PANNEL to reset VI, but a key of keyboard
please help me
thank you

action when keyboard pressed:
1) you can set the focus active on the e.g. stop button - using the
proberty node - when you press enter the value of the stop button will
change.
2) you can set a shortcut to the button, in front panel: right mouse => advanced => key navigation
now your other questions:
why you want to change the file when you write a comment?
and rename the new file?
i think for this you must use the file name field

Hello,
I need to write a comment in any time, during the measurement is running.
If it is possible I can write the measuremnet in a excel file insted lvm file. but I don't know how do it.
I must achieve a signal and filter it. then I calculate the integral of this signal and record it in a file.
but I must write a comment during acquisition because the signal change in the time according my manipulation and
I write them on file to have corresponding between comment and values.
This is my VI file I hope it is clear!
Another thing. I would to change file in which write when a write comment to have a diffrent file for each conditions.

How can I write a comment in a file lvm

I use Write LabVIEW Measurement File to write my signal in a lvm file.
I want to insert a comment and I use a string control to comment.
when I insert a comment I write comment and push Return.
When I open file.lvm there is no comment!!!
Why??
Thank you

Hi ocramm,
see the attached VI, it's a simple example that writes a single waveform (X and Y axes) in a lvm file adding a comment.
The comment fills only the 1st row of the 3rd column . The position of the comment is always in the 1st row of a new column after the last column of the last signal.
I hope this help you.

Trying to write current aquired data to file while a continuous aquisition is occurring.

I have a vi named pj_pushbutton.vi in the attached library. The vi is aquiring data continuously. I have a button that when pushed will write the data to the file. It does this fine except that it seems to be writing the samples from the buffer immediately. I guess I want to aquire the latest samples not all the samples that are n the buffer so that I get the real time aquisition. When I push the button I have it set up to read the number of samples based on time on the front panel. I want to sample 2 seconds and it calculated the sample rate multiplies by the seconds to give me the number of samples. When I run the program the push the button to write the data to the file
it seems to be writing from all the recodes in the buffer not just the most current. So instead of taking 2 seconds to write the data it writes whatever is in the buffer immediately. How do I keep it from doing this? My file is attached in a zip. Thanks for your help.

Hi HAL,
I don't have time to figure out exactly what you are asking but I can offer this tid-bit that may be handy to know.
"Delete from array" will by default return the last eelement in an array. This is ewasier and cleaner than iterating through all the elements and just keeping the last.
Add some comments (fre labels) showing me where to look if you want me to be of more help.

Write data to multiple text files after specific size

Hello,
I wrote a code that contineously writes data to a text file. The problem is I am running this VI for long time and therefore this text file is being bigger in size e.g. more than 10MB. I want to split writing data in this text file after max 1MB size. Can anyone help ????
thanks in advance.

CMW.. wrote:
You could use the "File/Directory Info Function" in the Advanced File VIs and Function palette to check the size. If the file is too big. close it and create a new one.
I would use the Get File Position since this won't cause Windows to have to do so much. Assuming you are just writing and not setting the file position manually, this will return the size of the file in bytes (file position will always be at the end of the file).

Automator not working properly while setting comments and moving files to folders, how to proceed?

So, this is my workflow, i've converted it into a folder action and applied it to a folder called "Automator" in my desktop:
i've turned "show this action when the workflow runs" so I can see what is going wrong
here's what I get (each action happens to have a problem to it)
1) Get specified finder items
2/3) Filter / find finder items
those are there just to work for this simple porpouse: identify that i've dropped a pdf file in the "Automator" folder
I move the PDF
The workflows starts
4) Ask for a text
this would be a prompt for me to add a comment to go to the "Spotlight Comment" section when I click on "get info"
put instead I get this...
that's the directiory that the file is in!
so I type some random text that would go to the spotlight comment section
then click OK
5) Set Spotlight Comments for Finder Items
that's the actual action, it should have the text that i've inputted in the last step, but instead it has this:
(Text is the variable that i've setted up to be shown on the ask for text and set spotlight comment...)
so, I have to manually input the comments I want to be on the file
and click continue
6) Label Finder Items
That's the action where i'm suppose to choose the label color, so I do that and click continue
this should work, but the file doesn't change label at all
nothing happens.
7) Move Finder Items
It should move to the "untitled folder", but again, it doesn't.
and that's it.
It's a PDF file, but it's not recognized by the system as a PDF.
When it is recognized, if I move more than one PDF file, the workflow works for just one PDF, instead of working for all of them!
I would reeeeally appreciate any help
the whole point in this was for me not to buy Hazel, but I think I will end up buying it :/
thanks for any help anyone can give me!

hey red_menace, thanks veeeery much for your support, I really appreciate it
as you can notice, i'm new to the automator, i'm actually new to the whole software thing, I have no idea what I'm doing so I really appreciated your help, changed my life and made my day
BUT, it didn't work...
well, it did, partially
I still don't get any comments on the "Spotlight comments" area and when I convert the workflow to a folder action, it does not recognize the file!
here's my workflow:
here's what I did, step by step:
first I added find finder's items, that worked really well, but it labeled all the finders files that were in the folder AND subfolders (the ones that were suppose to already be labeled right)
then I removed the find finder's items and tried, worked well, but I hadn't checked the "ignore the input", so the comments weren't working
so then I ignored the input on the actions that didn't require an iput, so my workflow is the same as yours now… and It's not working.
at first it worked for only 1 pdf, but no comments
then it worked for 50% of the pdfs, with comments
then it stopped working at all.
added the find finders items
worked while testing with one
saved
tried with 7 at the same time
worked… but didn't get any spotlight comments
went back on automator
checked "show this action when the workflow runs" for the spotlight comments action
added the variable as an answer on the "ask for text"
the variable ran as expected, I had the same input I've inputed as an answer for the "ask for text" on the "spotlight comments" action, label went okay and stuff, but i did not get any spotlight comment on the spotlight comment section!!
went back on automator and checked out the "append to existing comments" on "set spotlight comments for finder items"
and still didn't get any comments on the files!
btw, I went back on the automator and removed the find finder items
then tried again with only one file, dropping it in the application. it worked, but I still didn't get any spotlight comments!!
I also tried deleting the ask for text and tried just
but it did not work
I also converted the workflow that working for all expect the comments to a folder action, and it DID NOT recognize the pdf I dropped in the folder, what do I do?!

Control where a LabVIEW executable write it's Settings Configuration file

Is there any way to control which directory a LabVIEW executable writes it's configuration settings file to? I am using version 7.1.

I believe the INI file must be in the same directory as the executable. You can use the keys found in the LabVIEW.ini file and they will apply to your executable without any special programming on your part. That being said, you can always create a custom settings file or files anywhere you like to store configuration information specific to your application.
If we could specify some other path for the executable settings file, it would probably hurt more than help in the long run. The same directory as the executable is the only one whose existance you can be sure of..... or of whose existance you can be sure.

How to write data to an XML file present under application server

frnds: can ne one tell me, how to write data in to a file, which is present under a application server
Ex: i want to write a string data in to a file test.txt which is present under "http://localhost:8080/<some_webapp>/test.txt"
Note:i have deploted a service<some_webapp> under Tomcat/webapps dir

Very simple. A servlet can writes to that file if it has the good rights.
In the servlet get (or post) method, use a code like this:
import java.io.*;
protected void doGet(HttpServletRequest req, HttpServletResponse resp) {
try {
String filePath = this.getServletContext().getRealPath("/text.txt");//See http://java.sun.com/products/servlet/2.2/javadoc/javax/servlet/ServletContext.html#getRealPath(java.lang.String)
         PrintWriter writer = new PrintWriter (filePath);
        //or BufferedWriter out = new BufferedWriter(new FileWriter(filePath));
        writer .println("aString");
       writer.flush();
        writer .close();
    } catch (Exception e) {
       e.printStackTrace();
}Hope That Helps

Write arrays into a text file in different columns at different times

Hi,
I have a problem write data into a text file. I want to write 4 1D arrays into a text file. The problem is that I need to write it at different time and in different column (in other word, not only append the arrays).
Do you have an idea to solve my problem?
Thank you

A file is long a linear string of data (text). In order ro insert columns, you need to rewrite the entire file, because colums are interlaced over the entire lenght of the file.
So:
read file into 2D array
insert columns using array operations
write resulting 2D array to file again.
(Only if your colums are guaranteed to be fixed width AND you know the final number of colums, you could write the missing columns as spaces and then overwrite later. Still, it will be painful and inefficient, because column data are not adjacent in the file.)
LabVIEW Champion . Do more with less code and in less time .

The first binary file write operation for a new file takes progressively longer.

I have an application in which I am acquiring analog data from multiple
PXI-6031E DAQ boards and then writing that data to FireWire hard disks
over an extended time period (14 days). I am using a PXI-8145RT
controller, a PXI-8252 FireWire interface board and compatible FireWire
hard drive enclosures. When I start acquiring data to an empty
hard disk, creating files on the fly as well as the actual file I/O
operations are both very quick. As the number of files on the
hard drive increases, it begins to take considerably longer to complete
the first write to a new binary file. After the first write,
subsequent writes of the same data size to that same file are very
fast. It is only the first write operation to a new file that
takes progressively longer. To clarify, it currently takes 1 to 2
milliseconds to complete the first binary write of a new file when the
hard drive is almost empty. After writing 32, 150 MByte files,
the first binary write to file 33 takes about 5 seconds! This
behavior is repeatable and continues to get worse as the number of
files increases. I am using the FAT32 file system, required for
the Real-Time controller, and 80GB laptop hard drives. The
system works flawlessly until asked to create a new file and write the
first set of binary data to that file. I am forced to buffer lots
of data from the DAQ boards while the system hangs at this point.
The requirements for this data acquisition system do not allow for a
single data file so I can not simply write to one large file.
Any help or suggestions as to why I am seeing this behavior would be
greatly appreciated.

I am experiencing the same problem. Our program periodically monitors data and eventually save it for post-processing. While it's searching for suitable data, it creates one file for every channel (32 in total) and starts streaming data to these files. If it finds data is not suitable, it deletes the files and creates new ones.
On our lab, we tested the program on windows and then on RT and we did not find any problems.
Unfortunately when it was time to install the PXI on field (an electromechanic shovel on a copper mine) and test it, we've come to find that saving was taking to long and the program screwed up. Specifically when creating files (I.E. "New File" function). It could take 5 or more seconds to create a single file.
As you can see, field startup failed and we will have to modify our programs to workaround this problem and return next week to try again, with the additional time and cost involved. Not to talk about the bad image we are giving to our costumer.
I really like labview, but I am particularly upset beacuse of this problem. LV RT is supposed to run as if it was LV win32, with the obvious and expected differences, but a developer can not expect things like this to happen. I remember a few months ago I had another problem: on RT Time/Date function gives a wrong value as your program runs, when using timed loops. Can you expect something like that when evaluating your development platform? Fortunately, we found the problem before giving the system to our costumer and there was a relatively easy workaround. Unfortunately, now we had to hit the wall to find the problem.
On this particular problem I also found that it gets worse when there are more files on the directory. Create a new dir every N hours? I really think that's not a solution. I would not expect this answer from NI.
I would really appreciate someone from NI to give us a technical explanation about why this problem happens and not just "trial and error" "solutions".
By the way, we are using a PXI RT controller with the solid-state drive option.
Thank you.

How to enable commenting into pdf files using java?

Hi All,
Is there any way available to enable comments into pdf files through java. I have a Adobe Reader 9 and also I want put some comments into pdf file, but the reader is not allowed to place a comment into pdf file before enabling the Comments into pdf. After enabling the comments in pdf file then only we can place the comments and we can the pdf file with comments.
Is there any way available to enable comments into pdf file to view acrobat reader.
Thanks in advance.

The end user who uses the web application has Acrobat installed in their mahcine needs it only for the purpose of enabling comments in pdf. If this task of enabling comments in pdf is done through my application there is no need for acrobat in such user's machine which was requested as a cost cuttnig measure.
For this purpose, i need to know about how to enable comments in pdf through java api.
I have used itext java api for other pdf related manipulation in java. But it does not have feature as per the requirement posted above. Can any body suggest relevant java api to achieve the task requested?
Tahnks in Advance.
