Importing txt-files in Labview

Hello,
I am a beginner in programming labview applications so its possible my next question is very easy to program but i dont know how
My question is about importing a txt-file (csv-format) in labview. This txt-file is updated every 10 minutes and I want to visualise the last values every 10 minutes. These values must be written in several indicators (example: 10 coloms -> 10 indicators)
Next is a copy of the txt-file (this one is updated every second).

I found a template (Load file from and display) thats displays a value from a txt-file.
In the block: "Read LabView Measurement File" its possible to select an option to read from a generic text file, with the right delimiter and decimal point sign (, and .) and when i press the button read file now i see the values in the txt-file. But when I run the program i get a error with possible reason "End of file encountered".
Next I put in the block "Wait until next ms Multiple" put still the same error appears.
So this doesnt work!
How can I solve my problem? Can somebody give me some usefull tips? Has someone else encountered this problem yet? ....
Thank you.
Regards,
Kevin Duerloo

Hi Kevin
Do you mind posting your VI ? Or are u only using the supplied example and nothing else ?
Could it be your programm (which creates the file) doesn't close it when it's done creating?
Try rebooting the system and immediately after that try the labview thing. Does the error still occur ?
Hello,
I'm only using the supplied example, the programm closes when it's done creating and rebooting doenst help.
The error means end of file encountered so i think the file isnt updated quick enough for labview. I'm going to try error handling like JorisV said. I will keep you informed if this works or doesnt (I have a lot work so this will not be earlier than tomorrow)
Thank you for the replies.

How to get string (specified by line and column) from txt file with labview

Hi everyone
How to get string (specified by line and column) from txt file with labview
thx
Solved!
Go to Solution.

As far as I know, a text file has no columns. Please be more specific. Do you mean something like the 5th word on line 4, where words are separated by a space, and lines are separated by a newline character? You could the Read from Spreadsheet String function and set the delimiter to a space. This will produce a 2D array of strings. Then use index array and give the line number and column number.

Import txt file into report

I have an Arinc signal that I have decoded into each of its digital I/Os. Since I have over 150 I/Os I needed a way to sort and do a quick report on them.
I have three categories.
1. Stayed =1 throughout test
2. Stayed = 0 throughout test
3. Changed either from 0 --> 1 or 1-->0 during the test.
I want to just put a list of the signals for each of these categories into my report.
I have created a txt file for these to go in, but how do I import that into my report?
Or is there an easier way?
Here is an example of my code...

Hi 2Pale4TX,
You can't easily reference the content of an ASCII file. Instead, I suggest you make a new Group of 3 text channels that you can drag onto a REPORT table.
Dim k, m, z, ResultsGroup, TrueChannel, FalseChannel, ChangeChannel, Group, Channel, Result
Set ResultsGroup = Data.Root.ChannelGroups.Add("Results")
Set TrueChannel = ResultsGroup.Channels.Add("ArincTrue", DataTypeString)
Set FalseChannel = ResultsGroup.Channels.Add("ArincFalse", DataTypeString)
Set ChangeChannel = ResultsGroup.Channels.Add("ArincChange", DataTypeString)
For k = 2 to 4
Set Group = Data.Root.ChannelGroups(k)
For m = 1 to Group.Channels.Count
Set Channel = Group.Channels(m)
ChMax = CMax(Channel)
ChMin = CMin(Channel)
Result = ChMax - ChMin
If Result = 0 and ChMax > 0 Then
z = TrueChannel.Size + 1
TrueChannel(z) = Channel.Name
Elseif Result = 0 and ChMax = 0 Then
z = FalseChannel.Size + 1
FalseChannel(z) = Channel.Name
Else
z = ChangeChannel.Size + 1
ChangeChannel(z) = Channel.Name
End If
Next ' m
Next ' k

There are no readers registered for the txt type - Issue importing txt file

Hello guys,
I am working on SQL developer 3.2. and Oracle database 11g. I am trying to import a txt file with only two columns and 100 rows separated with a pipe. I can import the same file if its in *.CSV or *.xls format. I right click on the table > Import table > Choose the *.txt file > and then I get a message "There are no readers registered for the txt type". Why? Where do I get the reader? I am using the same exact method and the same exact data to import using a different file format and I do not get any errors. The wizard comes up and I am ready to load. I have scoured through this forum for a solution and I could not find one. Any help is very much appreciated.
Thank you!

It means we don't support that file type for doing imports. It sounds like a reasonable request to [add to the Exchange|sqldeveloper.oracle.com] though.

Bullet character in imported TXT file

I am importing an external TXT file into a dynamic text box
in my SWF file using Actionscript (see AS below).
I want the text to read as a bulleted list.
I tried typing the bullet character (Option + 8 on Mac), but
this gave me Yen symbols when I previewed the movie.
Then I tried the HTML code <UL>, <LI>, etc.,
which just showed exactly as typed when previewed.
I also tried the HTML code for this character ()
but this also showed exactly as typed when previewed.
How do I create the bullet character in Flash? Is there a
reference for creating all types of special characters in Flash?
Or is there a simple way to create a bulleted list?
Many Thanks,
Nathan

Mac OS 10.4.10
Flash CS3

for html content you would need to use external_txt.htmlText
= event.target.data;. also embed the basic font and the specific
"•" character
if you wanted to go the character code route you would have
to strip the character code from the string first and replace it
with a bullet.

Can't Import txt file in QTPro

I am trying to add Chapter Markers to a quicktime movie prior to bringing it into iDVD. Following the instructions in "QuickTime Player Help" section I made a txt file with chapter titles and timecode in the correct script. The "help" sheet tells me to "Save the text file and import it into QuickTime Player." Great- but there is no "import" choice in the drop down menu under "File."
I have deleted QuickTime and reimported it three times and tried re-purchasing QTPro. What am I not doing correctly?
Thanks,

Kirk-
I did write as plain text but found my own error elsewhere. I had inadvertantly added a carriage space after each chapter marker. When I brought them into QuickTime the first time, these carriage returns created a space for a new chapter heading after each real chapter heading. When I applied time code placements to my real titles, I did not understand I had also created bogus, blank titles. These had non-sense time code stamps and so QuickTime rejecting the file.
"Open File" replaces the "Import File" command in this version but all is well. User error.
Thanks,

Import txt file

Hi all.
I'm on SQL Developer 3.1.07.
I have a little question: is it possible to import a txt file using sql developer?
When I try it, it gives me this error:
no process reading recorded for the type txt
How can I load data into my database, txt file in particular, using sql developer??
Thanks all for collaboration,
Fabrizio Delli Priscoli

You may be able to import a text file if it is formatted in a way that meets the requirements of a delimited file. You can try renaming the file to have a .dsv extension (delimiter separated value). This will allow you to open the file with the import wizard. On the first page, select a delimiter that seems appropriate depending on the contents of the file (space, tab?).
However, you may find that the columns can not be detected correctly by the import wizard because the fields are not marked by a fixed delimiter, which is a requirement of the import wizard.
Good luck.

Thanks in advance

Hi,
Below example using External Table Feature.
create a directory on the server where your database is installed and copy your data file(text file) in that directory. In the below example Oracle directory name is "text_file" and the physical directory on the server is "D:\TEXT_FILE\". The file name of data file is "data.txt".
create directory text_file as 'D:\TEXT_FILE\';
DROP TABLE load_a;
CREATE TABLE load_a
(a1 varchar2(20),
a2 varchar2(200))
ORGANIZATION EXTERNAL
(TYPE ORACLE_LOADER
DEFAULT DIRECTORY text_file
ACCESS PARAMETERS
(FIELDS TERMINATED BY ','
LOCATION ('data.txt')
select * from load_a;
now you can use
insert into a select * from load_a;

Special Characters and Importing .TXT files

I am trying to import a .txt file that has special Characters. The ñ works correct, but the ® does not import correctly. Any Ideas?

What is strange is that if I open the .txt file up on a windows machine the ® is there.
When placing your text file, check the "Import Options" box. You can choose platform, encoding, and, um, um, something else. But you need to specify Windows platform, I think. You might need to specify your encoding as well. You can use an app like TextWrangler or Ultraedit or something else to figure out your text encoding. Or you can use the Drunkard's Walk algorithm: just keep trying encodings randomly until you find the one that works.

Automator-How to batch import txt files into excel

Hi
I have been using Automator to import hundreds of text files into one excel workbook using the "Import Text files to Excel Workbook" action. Automator works great for all files that are tab delimited. However I have another set of data that are output with a varying amount of spaces between each column. I cannot change the way they are output. Automator gives me the option of choosing "space" as a delimiter, but it wont give me the option to "Treat consecutive delimiters as one" that Import within excel does. I also tried to record my actions within excel many times but it didn't work even with just one file. So what I need is a way to get these text files into one excel workbook as separate worksheets with the data separated correctly into columns.
Any help would be great!

I'm confused by the "I cannot change the way they are output" line: What's stopping you from reimporting them into excel and resaving them as tab delimited? Converting from fixed-format to tab-delimited is always a bit of a pain (it involves chunking each line to the correct sized bits and then stripping whitespace from the end - doable in applescript and shell scripting, but a headache to get right); no sense remaking the wheel if you can get Excel to do it for you.
