User Input from Text File
Hello
I would like to incorporate code into this to allow the script I found on the internet to pull input from a txt file and then wait for the script to end before using the next entry in the text file and run until all entries in the text file have been used.
Any help would be great thx.

asked about.
Jason
I do not know which script you had in mind but the one I looked at had 1,600 lines of code. As you say, posting it here would be inappropriate. At the same time it is unrealistic to ask for help for such a large script. Asking the author is one option. The
other option would be to identify the module you wish to modify, analyse it until you fully understand it, modify it so that you can run it in a stand-alone manner, then post your question here. You will probably find that you can answer the question yourself
after analysing the code!

Help with inputting from text file.
Okay, been struggling with this for a couple days and I could really use some help.
I need to input text one line at a time into String[] text, I'm reading from a file called "textfile.txt" and I want to store the result
String[] text = { first_line, second_line, third_line, fourth_line...........etc}
This works now:
//code
String[] test =
{ "1 2, 3 4, 5 6"
for (int i = 0; i < test.length; i++) {
Graph g = new Graph(test);
// end code
But that of course reads "1 2, 3 4, 5 6" from the code, and not from a text file. My StringTokenizer looks for a "," and makes that the end of the token, so I need to add a "," after each line as well.
In other words, I need to turn the text file :
"1 2
3 4
5 6"
into :
"1 2, 3 4, 5 6"
These are just numbers to test of course, the real text file I need to input has hundreds of lines.
Any help would be appreciated, thank you.I'm fairly lost. I understand that you need to read a file, and that file contains many lines which each contain a pair of numbers. But then you say (a) that you need to create an array of Strings and (b) that you need to store the result. And there's this mysterious StringTokenizer in there as well. You seem to be suggesting some solution that concatenates all the lines together, with commas between them, so that the StringTokenizer can then go through that concatenation and break it apart into the original pieces.
Okay, here's some code that reads through a file and makes an array of Strings, one entry per line:BufferedReader in = new BufferedReader(new FileReader("textfile.txt"));
String data = null;
List inputs = new ArrayList();
while ((data = in.readLine()) != null) {
inputs.add(data);
in.close();
String[] lines = new String[0];
lines = (String[]) inputs.toArray(lines);Untested, and exception handling and so forth omitted. I leave it to you to decide what to do with that array of Strings.

Getting input from a file(user I/O redirection)
alright i am stuck on this program. Heres what i have to do
I have to write a program usinbg arrays and looping. The program should get its input from a file (user I/O redirection). The first number in the file will be the number of numbers that follow to find the average of (maximum of 100) and print if they are above or below the average.
I have called the program lab9.java. I already made a file called lab9.dat. This is whats inside the lab9.dat file.

16 is how many numbers i am using.
I am just stuck on how i should do this.
I have to have the program look at those numbers from that file and then calculates the average and then it has to look at each individual number and print out if that number is above or below average. First off im getting an error when i put in java lab9 < lab9.dat. Am i messing up somewhere.
I also have the loop:
int numnums = cisio.GetInt();
double nums[] = new double[numnums];
int k;
for(k=0;k<numnums;k++)
nums[k]=cisio.GetInt();
This is where im stuck. I need the program to get the average of the numbers and then compare each number to the average and say if its above or below average. I dont know how to do that. If someone can help me out that would be great.Yes, you would need three loops: one to get the input, other the calculate the sum, and a third to print out what numbers are less than and what more than the average. That is the easiest thing to do. It's possible to combine getting the input and calculating the sum in one single loop though. I'm glad you got it working! :)

How to accept user inputs from sql script
I want to create Tablespace useing sql script , but the location of the data file I need accept from user . (to get the location of the data file ) .
How can I accept user input from pl/sql .
Example :
CREATE TABLESPACE TSPACE_INDIA LOGGING
DATAFILE 'H:\ORACLE_DATA\FRSDB\TSPACE_INDI_D1_01.dbf'
SIZE 500M AUTOEXTEND ON NEXT 1280K MAXSIZE UNLIMITED
EXTENT MANAGEMENT LOCAL;here I need to accept location of the datafile from user ie : 'H:\ORACLE_DATA\FRSDB\TSPACE_INDI_D1_01.dbf'Hi,
Whenenever you write dynamic SQL, put the SQL text into a variable. During development, display the variable instead of executing it. If it looks okay, then you can try executing it in addition to displaying it. When you're finished testing, then you can comment out or delete the display.
For example:
SET SERVEROUTPUT ON
DECLARE
flocation VARCHAR2 (300);
sql_txt VARCHAR2 (1000);
BEGIN
SELECT '&Enter_The_Path'
INTO flocation
FROM dual;
sql_txt := 'CREATE TABLESPACE SRC_TSPACE_INDIA LOGGING
DATAFILE' || flocation || ' "\SRC_TSPACE_INDI_D1_01.dbf" ' || '
SIZE 500M AUTOEXTEND ON NEXT 1280K MAXSIZE UNLIMITED
EXTENT MANAGEMENT LOCAL ';
dbms_output.put_line (sql_txt || ' = sql_txt');
-- EXECUTE IMMEDIATE sql_txt;
END;
/When you run it, you'll see something like this:
Enter value for enter_the_path: c:\d\fubar
old 5: SELECT '&Enter_The_Path'
new 5: SELECT 'c:\d\fubar'
CREATE TABLESPACE SRC_TSPACE_INDIA LOGGING
DATAFILEc:\d\fubar
"\SRC_TSPACE_INDI_D1_01.dbf"
SIZE 500M AUTOEXTEND ON NEXT 1280K MAXSIZE
UNLIMITED
EXTENT MANAGEMENT LOCAL = sql_txt
PL/SQL procedure successfully completed.This makes it easy to see that you're missing a space after the keyword DATAFILE. There are other errrors, too. For example, the path name has to be inside the quotes with the file name, without a line-feed between them, and the quotes should be single-quotes, not double-quotes.
Is there some reason why you're using PL/SQL? In SQL, you can just say:
CREATE TABLESPACE SRC_TSPACE_INDIA LOGGING
DATAFILE '&Enter_The_Path\SRC_TSPACE_INDI_D1_01.dbf'
SIZE 500M AUTOEXTEND ON NEXT 1280K MAXSIZE UNLIMITED
EXTENT MANAGEMENT LOCAL;though I would use an ACCEPT command to given a better prompt.
Given that you want to use PL/SQL, you could assign the value above to sql_txt. If you need a separate PL/SQL variable for flocation, then you can assign it without using dual, for example:
DECLARE
flocation VARCHAR2 (300) := '&Enter_The_Path';The dual table isn't needed very much in PL/SQL.

LabVIEW for ARM 2009 Read from text file bug
Hello,
If you use the read from text file vi for reading text files from a sdcard there is a bug when you select the option "read lines"
you cannot select how many lines you want to read, it always reads the whole file, which cause a memory fault if you read big files!
I fixed this in the code (but the software doesn't recognize a EOF anymore..) in CCGByteStreamFileSupport.c
at row 709 the memory is allocated but it tries to allocate to much (since u only want to read lines).
looking at the codes it looks like it supposed to allocated 256 for a string:
Boolean bReadEntireLine = (linemode && (cnt == 0));
if(bReadEntireLine && !cnt) {
cnt = BUFINCR; //BUFINCR=256
but cnt is never false since if you select read lines this is the size of the file!
the variable linemode is also the size of the file.. STRANGE!
my solution:
Boolean bReadEntireLine = (linemode && (cnt > 0)); // ==
if(bReadEntireLine) { //if(bReadEntireLine && !cnt) {
cnt = BUFINCR;
and now the read line option does work, and reads one line until he sees CR or LF or if the count of 256 is done.
maybe the code is good but the data link of the vi's to the variables may be not, (cnt and linemode are the size of the file!)
count should be the number of lines, like chars in char mode.
linemode should be 0 or 1.
Hope someone can fix this in the new version!
greets,
Wouter
Wouter.
"LabVIEW for ARM guru and bug destroyer"I have another solution, the EOF works with this one.
the cnt is the bytes that are not read yet, so the first time it tries to read (and allocate 4 MB).
you only want to say that if it's in line mode and cnt > 256 (BUFINCR) cnt = BUFINCR
the next time cnt is the value of the bytes that are not read yet, so the old value minus the line (until CR LF) or if cnt (256) is reached.
with this solution the program does not try to allocate the whole file but for the max of 256.
in CCGByteStreamFileSupprt.c row 705
if(linemode && (cnt>BUFINCR)){
cnt = BUFINCR;
don't use the count input when using the vi in line mode. count does not make sense, cnt will be the total file size. also the output will be an array.
linemode seems to be the value of the file size but I checked this and it is just 0 or 1, so this is good
update: damn it doesn't work!
Wouter.

Read from Text File - Help Bug?
Hi - I am currently working on LV8 and I think that there is some misunderstanding potential in the help file. To be more exact in the help to the "Read From Text File" VI.
The description for "count":
" ... If count is <0, the function reads the entire file. The
default is –1, which indicates to read a single line if you placed a checkmark
next to the Read Lines shortcut menu item and to read the
entire file if you removed the checkmark next to the item. "
If count is lower than zero, the function reads the entire file. That sounds clear to me.
The default is -1, which indicates to read a single line if you placed a checkmark next to the "Read Lines" shortcut menu item. Now what? Does it read a single line or the whole file?
.. and to read the entire file if you removed the checkmark next to the item. I thought it reads the whole file if I use -1 ?
the VI itself behaves as I'd expect it to:
* If I place a checkmark next to Read Lines and put -1, I get an array containing the lines
* If I remove the checkmark, I get only a single string item.
Now where is the error? Is the VI not working properly or only the description a little bit ... strange ??hein??
?what?
Both you guys lost me..
And I drink coffee without sugar (being sweet enough, already)
Here is what I get from Context Help on the Read From Text File:
Read from Text File
Reads a specified number of characters or lines from a byte stream file. By default, this function reads all characters from the text file. Wire an integer value to count to specify how many individual characters you want to read starting with the first character. Right-click the function and place a checkmark next to the Read Lines option in the shortcut menu to read individual lines from the text file. When you select the Read Lines option in the shortcut menu, wire an integer value to the count input to specify how many individual lines you want to read from the file starting with the first line. Enter a value of -1 in count to read all characters and lines from the text file.
Humm.
New feature (again).. If you select checkmark the Read Lines option, it will not send the text to a sting indicator, as shown in the attached image. If selected, then it's expecting to write lines to an array of strings... WHY??? I don't know.. I'll ask..
Strange... LV8 is full of mysteries...

Read from Text File Detailed Help need Clean-up
This is probably well known and nobody has bothered fixing it but the detailed Help of the "Read from Text File" function is sort of ambiguous:
- statement 1: refnum out is the refnum of the file that the function read. You can wire this output to another file function, depending on what you want to do with the file. The default is to close the file if it is referenced by a file path or selected from the file dialog box. If file is a refnum or if you wire refnum out to another function, LabVIEW assumes that the file is still in use until you close it.
- statement 2: If you wire a path to file, the function opens the file before reading from it and closes it afterwards.
I have found statement 1 to be correct, which makes statement 2 incomplete (and sort of tautological in the sense that 1) you expect LabVIEW to open the file before reading from it if you provide a path instead of a refnum... and 2) if you use a path input to file AND use the refnum out for some other function, the file is NOT closed, as correctly stated in statement 1).
Just sayin' ...X,
It deeply concerns me that you would take my response to mean indifference. I certainly had no intention to belittle what you had to say. On the contrary, I took this up with the concerned team, and had a small discussion. If you say that what someone says on this forum is of lesser or no value to National Instruments, you could not be more wrong. It defeats the whole purpose of this public forum.
My point was not that it is not an issue, it certainly seems to be. Please be rest assured that even if it does not look like it from the outside, each comment however big or small is taken back to our workplaces and some thoughts poured over it.
On the whole, I recognise that I had a role to play in this misunderstanding of tone, and I sincerely apologise.

Why does Read from Text file default to array of 9 elements
I am writing to a text file starting with a type def. cluster (control) of say 15 dbl numeric elements, that works fine I open the tab-delimited text file and all of the elements appear in the file. However when I read from the same text file back to the same type def. cluster (indicator), the read from text file defaults to 9 elements?? Is there a way to control how many elements are read from the file. This all works great when I initially use a cluster of 9 elements and read back to a cluster of 9 elements.
Solved!
Go to Solution.From the LabVIEW Help: http://zone.ni.com/reference/en-XX/help/371361G-01/glang/array_to_cluster/
Converts a 1D array to a cluster of elements of the same type as the array elements. Right-click the function and select Cluster Size from the shortcut menu to set the number of elements in the cluster.
The default is nine. The maximum cluster size for this function is 256.

How to open saved files using 'read from text file' function
Hi everyone, I am having a hard time trying to solve the this particular problem ( probably because I am a newb to lanbview ). Anyway , I am able to save the acquired waveforms by using the 'Write to text file' icon. I did manually modify the block diagram of the 'Write to text file' icon and create the correct number of connector so as to make my program work. But now I have no idea on how to modify the block diagram of the 'Read from text file' block diagram to make my program 'open' my saved waveforms. Or i do not have to modify anything from the block diagram of the 'Read from text file'? Can anyone teach/help me connect up? Do i need the build array on the "open" page?
Here are some screenshots on part of my program
let me know if you guys would need more information / screenshots thank you!

Actually i am going to replace those 'signal generators sub vi' with ThoughtTechonology's sample code so i can obtain data waveforms real-time using Electrocardiography (ECG) ,Electromyography (EMG ) and Electroencephalography (EEG) hopefully i can find out how to connect the sample code.
( ps . cant connect it now unless my program is working otherwise labview will crash )
( p.s.s the encoder of my biofeedback trainer already acts as an DAQ so i wont need to place an DAQ assistant in my block diagram i suppose )

Trying to parse a file-read from text file.vi
I'm attempting to read a txt file that has tab separated data. In the fourth (or any) column is the only data I need. The data is a string of numbers (23.454).
I've used the Read from Text File.vi and the Read From Spreadsheet.vi and I just don't seem to have enough LV background to extract the pertinent data into a graph. any suggestions?(It is silly to use "delete from array" if all you want is a column. The correct function is "index array")
Joe's idea above basically works fine. Here's a quick adapdation (the node before the graph is "index array" from the array palette.).

Set a timeout for "read from text file"
I Need to read from a text file on a remote pc and use the read from text file function to do this. It wotks but sometimes this pc is down causing long wait times in my vi.
Is there a way to set a timeout for the read from text file function, or is there an other solution?
Thank youYou could check that the path is valid first before you attempt to read the file. hen put the file read in a True-False case structure based on the results of the check. You can use the function "Check if File or Folder Exists" It checks whether a file or folder exists on disk at a specified path. This VI works with standard files and folders as well as files in LLB files. The function is found in the File I/O --> Advanced File Functions palette.

Read from text file vi won't read file...
I am very new to LV programming so I hope you forgive any stupid mistakes I am making. I am using Ver. 8.2 on an XP machine.
I have a small program that stores small data sets in text files and can update them individually or read and update them all sequentially, sending the data out a USB device. Currently I am just using two data sets, each in their own small text file. The delimiter is two commas ",,".
The program works fine as written when run in the regular programming environment. I noticed, however, as soon as I built it into a project that the one function where it would read each file sequentially to update both files the read from text file vi would return an empty data set, resulting in blank values being written back into the file. I read and rewrite the values back to the text file to place the one updated field (price) in it'sproper place. Each small text file is identified and named with a 4 digit number "ID". I built it twce, and get the same result. I also built it into an installer and unfortunately the bug travelled into the installation as well.
Here is the overall program code in question:
Here is the reading and parsing subvi:
If you have any idea at all what could cause this I would really appreciate it!
Solved!
Go to Solution.Hi Kiauma,
Dennis beat me to it, but here goes my two cents:
First of all, it's great to see that you're using error handling - that should make troubleshooting a lot easier. By any chance, have you observed error 7 when you try to read your files and get an empty data set? (You've probably seen that error before - it means the file wasn't found)
If you're seeing that error, the issue probably has something to do with this:
Relative paths differ in an executable. This knowledge base document sums it up pretty well. To make matters more confusing, if you ever upgrade to LabVIEW 2009 the whole scheme changes. Also, because an installer contains the executable, building the installer will always yield the same results.
Lastly, instead of parsing each set of commas using the "match pattern" function, there's a function called "spreadsheet string to array" (also on the string palette) that does exactly what you're doing, except with one function:
I hope this is helpful...

'read from text file' erases the file
I am trying to read text in from a text file. This is the exact code I am using. For some reason the output from 'read from text file' contains all the text that was originally in the file, but after the code executes the file is empty. I have several other vi's which use the same code and the file is fine. But whenever I run this code in this one specific vi the text file gets erased.
What is in the rest of that "specific vi"? I just tried the code you show, in v2011, and it works as expected, doesn't clear file.
What version are you running? Can you add an error out, or make sure error output is on in your LabVIEW configuration?
