Build Array and Output Values to Text or Excel File

I know this is a simple question but I need some help. I'm reading a DC voltage in LabVIEW a while loop. I want to store all the read values into an array and export that array as an text or Excel file. I had a VI that I build before for this but I cannot seem to find it and I can't remember how I did it before. Any help is appreciated. I think I can do the exporting part but I do help with building the array (storing all the data values).

I run into a problem while using the "Write to Text File Function". Initially I took about 60 measurements and wrote to a text file. That works but I increased the amount of measurements to be taken to 600 and when I did that the output in the text file are all Chinese letters (or that's what it seems like). Is this because I'm writing too much data?
When I use the "Write To Spreadsheet File VI" to write the measurments it works fine for the 600 measurements. The problem with this is I cannot insert any text. Using the "Write to Text File Function" I inserted some text before the measurements and "end of lines", to format the data. Attached is a screenshot of my VI.

Building array and writing to multiple files

Greetings,
I have a VI wherein, I am collecting data from 3 channels (using Global Virtual Channels with scaling). I am collecting 100 samples at a time with sampling frequency of 1000 Hz. I am then taking average and st. dev of 100 data points/channel and write it to a file (‘*.dat’). I would like to limit the file size to 1000 entries, and so after that limit is reached I would like to create a new file and write the subsequent set of data to the next file and so on. I am doing this in a case structure, wherein I build an array of the values until the condition of file limit is reached and then I write that array to a ‘*.dat’ file. (I’m hoping that this logic is correct, if not please suggest the correct method)
I am also taking average and st. dev of data/channel over period of 1 sec and write it to another ‘*.sum’ file. The VI has other features like writing time stamp to file, stopping the VI after preset time limit is reached or certain safety limit is reached.
When I run the VI, I get an error message:
Error 7 occurred at Open/Create/Replace File in Global Channel with Multiple file Write.vi
Possible reason(s):
LabVIEW: File not found. The file might have been moved or deleted, or the file path might be incorrectly formatted for the operating system. For example, use \ as path separators on Windows, : on Mac OS X, and / on Linux. Verify that the path is correct using the command prompt or file explorer.
=========================
NI-488: Nonexistent GPIB interface.
I have indicated the location of the error in the attached picture, as well as I’m attaching the VI.
I would really appreciate if someone would tell me what is causing the error and how to fix it.
Thanks,
Dinesh

Global Channel with Multiple file Write.vi ‏515 KB

I did try that but it does not solve the problem. I think I'm missing something while building the array in the Case Structure. I would like to write the average & st. dev values/channel in an array while the loop coount < file limit, and once the file limit is reached write that array to a *.dat file. And keep repeating this procedure till the target time is reached.
Another issue that I discovered is that TestFile_1.dat is not generted, after TestFile_0.dat TestFile_2.dat gets generated. I'm not sure why this is happening.
I would really appreciate if you would take another look and suggest some debugging tips.
Thanks.
P.S. I am attaching the updated VI

Reading long text from excel file to an internal table

Hi
Can any body tell me how to read long text from excel file to an internal table.
When i am using this FM KCD_EXCEL_OLE_TO_INT_CONVERT then it is reading only 32 characters from each cell.
But in my excel sheet in one of the cell has very long text which i need to upload into a internal table.
may i know which FM or what logic i need to use for this problem.
Regards

Hi,
Here is an example program. It will upload an Excel file with two columns. You could also assign the Excel structure dynamically, but I wanted to keep the example simple. The main point is that the internal table (it_excel in this example) must match the Excel structure that you want to convert.
Remember, this is just an example to help you figure out how to properly use the technique. It will certainly need to be modified to fit your requirements, and as always there may be a better way to get the Excel converted... this is just one possibility that has worked for me in the past.

You just read the same shared variable 100 times within a few nanoseconds. Apparently, the variable gets modified less often on the other end.
chendel wrote:

If all array values are the same, they are already sorted.
You need to rethink your code. maybe you can make the shared variable an array and write the entire random array on the other end, the read it out once.

Output autonumber as text in xml-file

Hi All,
just wanted to know if it is possible to take the autonumber that is created via the EDD or a paragraph format in the application template and put it in some attribute or - even better - output it as text in the xml-file.
Btw: I'm still using FM8, if that makes any difference.
Thanks for all suggestions,
Anna

Hi Anna,
Generally, an autonumber is considered part of the document's formatting so it is not normally exported to XML. I am not sure if there is a built-in way of assigning it to an attribute in FrameMaker, but you could do this with FrameScript if necessary.

How to store the data coming from network analyser into a text or excel file

Hii everyone
I'm using Agilent 8719ET network analyser and wish to store the data coming from netowrk analyser into a text file/ excel file.
Presently I'm able to get the data on Labview graph using GPIB . Can anyone suggest how to go ahead after collect data sub vi. How can the data be stored into a file apart from showing on the graph?
Attached is the vi for kind consideration...
Looking for help

First let me say that your code really looks pretty good. The data handling could be made more efficient by calculating the number of datapoints that are going to be in the completed dataset and preallocating the entire array -- but depending upon your answer to my questions, the logic in the lower shift register may be going away - so we won't worry about that right now.
The thing I need to know before addressing the data storage question is: Each time you call "Collect and Display Data.vi", how many element are in the array? Are you reading single data points, or a group of data? (BTW: if the answer to that question is obvious based on the way the other VIs are setup, I don't have the drivers so I can't tell what the setup values are.) Second, how fast does the loop iterate? Are we talking msec per loop?, seconds? fortnights?
The issues here are two-fold: how much data? and how fast is it coming? The answer to these will tell you how to save the data.

I want to read and use some informations from a excel file

To test a graphic, i need to take a lot of numbers in a excel file...
but i dont know how to open and read this file but i dont know how...
thx for your help...

Hello,
You can open, read, and even write excel files (if you write a file with extension .xls, windows will interpret it as an excel file be default) using the File I/O VIs in LabVIEW. To extract the data, all you really need to realize is that spreadsheets programs like excel store data with the following basic rules:
1. the entire spreadsheet is really just a large string - to read them, you just have to know the data you read is stored based on rules 2 and 3; to write them you just have to conform to rules 2 and 3.
2. cells in a given row are delimited by tabs (usually by default) and sometimes commas (but usually only if you set this specifically in the spreadsheet program)
3. rows are delimited by end of line characters, which will usually be one carriage return and one linefeed character in that order on windows.
In fact, for writing spreadsheet strings (which can be opened in excel) from LabVIEW, check out the Array to Spreadsheet String and Spreadsheet String to Array functions in the String Palette. That is, if you imagine the excel spreadsheet as a 2D array, those functions will essentially convert between the large string, and a 2D array in LabVIEW containing the values you would see in excel's corresponding cells.
I have attached a program that will use the array to spreadsheet string function to write an excel file containing those values - it will be named test.xls and should be on your C: drive directly. A good exercise to get started would be to write a VI using similar (some inverse) functions to read that string, and convert it back to an array.
I hope this helps!

Rename files using text or excel file

I am trying to find out how to rename files on my pc using the names stored in a text document
eg. the file on the pc is called "C07_08.dat"
the text file has the following line "3am Eternal KLF 03:15 121 BMG C07.08"
i want to change the name of the file "C07_08.dat" to "3am Eternal.mpeg"
What I would like is a batch file or program or something that will see the text "C07.08" and find the corresponding file "C07_08.dat" and rename it "3am Eternal.mpeg"
I have managed to create a excel document that has the information in four separate columns
Column A has the name of the file I want to use (ie. 3am Eternal) Column B & C have unneeded information and Column D has the file reference (ie. C07.08)
I was told that Python or Visual basic could do this so I downloaded them but I have no experience with this so im lost as to what to do, I have over 1800 of these files so doing it file by file will take quite a while.
I have included a sample of the text file for reference if that helps

Here are two VBScripts that will rename the files based on the text file example you provided. The script that reads a
TEXT FILE requires each entry to be separated by
ONE TAB because it is the
TAB
that it uses to split each line into 4 parts (part1 - old file name, part2 and part3 - items you don’t need, part 4 - new file name). If there is more that one tab then the Split Function will not work properly.
The second VBScript will read the
EXCEL FILE row by row and use the values in Column A for the old file name and
Column D for the new file name. This approach will work much better if you have an excel document setup like this.
I used your example that you provided and it test fine for both approaches.

How to get query result in comma dilimited text or excel file?

Does anybody know how to get query results in comma delimited
text file or excel file, I tried spool abc.txt, but the result
showed some ------ lines
Thanks

Try doing this in your sql scripts
set heading off
set pagesize 0
set linesize 4000
set feedback off
set verify off
set trimespace on
set colsep ","
spool output.txt
select * from dual (or whatever you are querying
spool off
There may be a couple other set statement that you could add but
this should get you started in the right direction

Just added Mavericks 10.9.1 and can no longer add an Excel file creating yesterday to an email message created on my MacBook Pro. I can locate the file in my Excel icon but not to attach to an email

Need help in attaching Excel files to emails......Excel spreadsheet created yesterday cannot be located to attach? The file can be located by entering the Excel icon but not visable when creating an email and attempting to attach.....seems to only inpact newly created files?

QR Codes generated and placed in Indesign from an Excel file

I'm in prepress for a printing company, and we have a project that I'm not sure how to handle. I have an Excel file with 40,000 names, titles, company, address, etc. AND the url for a QR code. I need to generate postcards with all the variable data in place, and use the URL info in the excel sreadsheet to generate a QR code AND place it - all in one action so I can print on the postcards the way I do all my data merge files.
Does anyone know how to do this? Is it even possible with InDesign? I would love to hear any solutions to this problem!
Thanks in advance!

Hi Cololitho,
I'm sorry to say at the time we don't have any in-depth documentation on Tada QR! as writing a vast amount of documentation takes a long time! We will add this in time.
Since Tada QR! handles bulk QRs by a search and replace, it means that if you can find a way to get the URLs into your InDesign document Tada QR can replace them with QRs.
The formula I used in the video in excel creates a new column that puts the data into the default format for Tada QRs search pattern.
It looks like this:
="<%"&A1&"%>"
Where "A1" is the name of the cell of the data you want to format.
I then drag/repeat the cell containing the formula down the length of the spreadsheet so it is repeated for each data item.
For example if you have urls:
http://www.urlone.com
http://www.urltwo.com
This should create a new column that looks like this
<%http://www.urlone.com%>
<%http://www.urltwo.com%>
If you can get the data in this format and into your InDesign document,
you should be able to select "Entire Document" and hit the "Replace All" button without having to change any of the default settings.
This will replace the all the URLs in that format with QR codes.
