Three sets of data to write to a text file
Hello
I think it will be a simple problem, but I'm stuck with it.
If someone could be so kind as to show me how to put 3 sets of data: V-time, parcel SPD, V ^ 2-time on vi, in a single txt file (to be used on a worksheet).
Please find attached vi.
Thank you.

Can all help with VI to get data (HEX) serial number and write in the text file
Hello I am struggling with this problem for 2 months... They get help from different I thought I solved the problem, but of no use yet I stand on zero
Problem: I need to get data on USB high speed HEXAGON shaped (coming in hexadecimal and be stored in the text file to the hexadecimal format as each hexadecimal value online different I'll also to attach the file)
Get us ASCII on series or VISA read but when trying to convert to hex as shown in text file making it slower to deal with code, I know that my VI will have to improve more... I'm waiting for suggestions
Need urgent help...
Thanks in advance
Hi Ali Afzal,.
I think that the attached example can work for you. If not, then try the solution with sending the data to a parallel running the loop and store it there.

I've been struggling with the "write to text file" in the part of the attached .vi button
I want to be able to say my program when I press on the Boolean key it should collect 1 sample point only from the mean.vi - now that I managed to do a Boolean-button that starts the collection of data and then I have to press the button again when I 'think' now, I collected a data point using the structure of the case.
Can someone help me to collect the data a not that when I press the Boolean?

Read/write to DB text file
Hello
What is the effective way of reading the text file and write to the DB table.
Forms Builder (10.2.0.3.0) - version
DB 10 g 2
Rgds
sexyHello
TEXT_IO is a software package, integrated forms. Webutil has too (but it's CLIENT_TEXT_IO, which can be read from the client computer), in which, plain TEXT_IO reads the file from the server computer.
As I said before, it depends on the number of records / size of the file. If he records little (say a few hundred), then you can go for TEXT_IO. However, if the size of the file is very high / you have more records (say thousands / millions), then SQL Loader is the best bet.
If you are worried about the performance (i.e. If you have more records to be inserted), you can create a batch script (which loads the data into tables using SQL Loader) and call the command script using the HOST of shapes command.
You can see the SQL Loader manual (which I gave the link before), for orders / check the syntax of the file etc and create a command script. Probably, if you're looking for the PL/SQL forum / forum SQL Loader, you will get more ideas and samples.

LonyHi Lony,
You may not use the operating system directory here.
You must create the directory object in oracle.
create or replace directory temp_dir as 'C:\temp'; grant read , write on directory temp_dir to hr; -- Username
To create any directory, 'create any directory of grant' privilege.
declare f utl_file.file_type; s varchar2(200) := 'Line 1'; begin f := utl_file.fopen('TEMP_DIR','NCW_ET15.log','W'); utl_file.put_line(f,s); utl_file.fclose(f); exception when NO_DATA_FOUND then utl_file.fclose(f); end; / show errors

Need help: UTL_FILE read and write in the text file
Hello, I'm on version 11 GR 2 by using the UTL_FILE function to read a text file and then write the lines where it starts with the word "foo" and put an end to my writing in the text file where the line with the word "ZEN". Now I have several lines that begin with 'foo' and 'ZEN' allow a paragraph, and in this paragraph, there is a line that begins with "DE4.2". Therefore,.
I need to write all of the paragraphs that include the "DE4.2" line in their beginning and end of lines 'foo' and 'ZEN '.
FOR EXAMPLE:
FOO/234E53LLID
IT'S MY SECOND LINE
IT'S MY THIRD LINE
DE4.2 IT OF MY FOURTH LINE
IT'S MY FIFTH LINE
ZEN/DING3434343
FOO/234E53LLID
IT'S MY SECOND LINE
IT'S MY THIRD LINE
IT'S MY FIFTH LINE
ZEN/DING3434343
I'm only interested in writing the first paragraph tha includes line DE4.2 in one of the paragraph of lines not the second ther that does not include the "DE4.2".
Here is my code so far:
CREATE OR REPLACE PROCEDURE my_app2 IS
Utl_file.file_type INFILE;
outfile utl_file.file_type;
buffer VARCHAR2 (30000);
b_paragraph_started BOOLEAN: = FALSE; -flag to indicate which required paragraph is started
BEGIN
-Open a file to read
INFILE: = utl_file.fopen ('TEST_DIR', 'mytst.txt', 'r');
-Opens a file for writing
outfile: = utl_file.fopen ('TEST_DIR', "Out.txt", "w");
-Check the file is open
IF utl_file.is_open (infile)
THEN
-lines in the file in loop
LOOP
BEGIN
UTL_FILE.get_line (infile, buffer);
APPLICATION STARTING POINT-
Buffer IF LIKE 'foo %' THEN
b_paragraph_started: = TRUE;
END IF;
-SEARCH FOR GRADS APPS
IF b_paragraph_started AND buffering LIKE '% 4% ' THEN
UTL_FILE.put_line (outfile, buffer, FALSE);
END IF;
-REQUEST FOR ENDPOINT
Buffer IF LIKE '% ZEN' THEN
b_paragraph_started: = FALSE;
END IF;
UTL_FILE.fflush (outfile);
EXCEPTION
WHEN no_data_found THEN
EXIT;
END;
END LOOP;
END IF;
UTL_FILE.fclose (INFILE);
UTL_FILE.fclose (outfile);
EXCEPTION
WHILE OTHERS THEN
raise_application_error ("-20099, ' UTL_FILE unknown error");
END my_app2;
/
When I run this code I get only one line: DE4.2 it ME LACK THE WHOLE PARAGRAPH
PLEASE ADVISE...I agree with reservations of Justin on the length of a "paragraph" and the number of users that are running at the same time, so here is a version without the collections.
CREATE or replace PROCEDURE my_app2 IS infile utl_file.file_type; outfile utl_file.file_type; buffer VARCHAR2(30000); b_paragraph_started BOOLEAN := FALSE; -- flag to indicate that required paragraph is started b_toprint BOOLEAN := FALSE; l_para_start pls_integer; -- start of "paragraph" BEGIN infile := utl_file.fopen('TEST_DIR', 'mytst.txt', 'r'); outfile := utl_file.fopen('TEST_DIR', 'out.txt', 'w'); LOOP BEGIN utl_file.get_line(infile, buffer); IF buffer LIKE 'FOO%' THEN b_paragraph_started := TRUE; l_para_start := UTL_FILE.FGETPOS(infile) - (length(buffer) + 1); END IF; IF b_paragraph_started and buffer like '%DE4%' THEN b_toprint := TRUE; END IF; If buffer like 'ZEN%' THEN IF b_toprint THEN UTL_FILE.FSEEK(infile, l_para_start); utl_file.get_line(infile, buffer); while buffer not like 'ZEN%' loop utl_file.put_line(outfile,buffer, FALSE); utl_file.get_line(infile, buffer); end loop; utl_file.put_line(outfile,buffer, FALSE); end if; b_paragraph_started := FALSE; b_toprint := false; utl_file.fflush(outfile); end if; EXCEPTION WHEN no_data_found THEN EXIT; END; END LOOP; utl_file.fclose(infile); utl_file.fclose(outfile); END my_app2;
Test:
SQL> !cat mytst.txt FOO/234E53LLID THIS IS MY SECOND LINE THIS IS MY THIRD LINE DE4.2 THIS IS MY FOURTH LINE THIS IS MY FIFTH LINE ZEN/DING3434343 FOO/234E53LLID THIS IS MY SECOND LINE THIS IS MY THIRD LINE THIS IS MY FIFTH LINE ZEN/DING3434343 FOO/234E53LLID again THIS IS MY second SECOND LINE THIS IS MY second THIRD LINE DE4.2 THIS IS MY second FOURTH LINE THIS IS MY second FIFTH LINE ZEN/DING3434343 again SQL> exec my_app2; PL/SQL procedure successfully completed. SQL> !cat out.txt FOO/234E53LLID THIS IS MY SECOND LINE THIS IS MY THIRD LINE DE4.2 THIS IS MY FOURTH LINE THIS IS MY FIFTH LINE ZEN/DING3434343 FOO/234E53LLID again THIS IS MY second SECOND LINE THIS IS MY second THIRD LINE DE4.2 THIS IS MY second FOURTH LINE THIS IS MY second FIFTH LINE ZEN/DING3434343 again
You may need to change the length (buffer) + 1 depending on your platform and if you want a blank line s NLE out paragraphs, add another call to put_line after that outside of the loop in the fi l_toprint block.

The monitoring of test data to write in the CSV file
Hi, I'm new to Labview. I have a state machine in my front that runs a series of tests. Every time I update the lights on the Panel with the State. My question is, how is the best way to follow the test data my indicators are loaded with during the test, as well as at the end of the test I can group test data in a cluster, and send it to an another VI to write my CSV file. I already have a VI who writes the CSV file, but the problem is followed by data with my indicators. It would be nice if you could just the data stored in the indicators, but I realize there is no exit node =) any ideas on the best painless approach to this?
Thank you, Rob
Yes, that's exactly what typedef are to:
Right-click on your control and select make typedef.
A new window will open with only your control inside. You can register this control and then use it everywhere. When you modify the typedef, all controls of this type will change also.
Basically, you create your own type as 'U8 numéric', 'boolean', or 'chain' except yours can be the 'cluster of all data on my front panel' type, "all the action my state machine can do," etc...

Write/close text file problems
There is probably a simple answer to this question, but I can't seem to understand.
I'm using a controller compact realtime RIO 9068
I have a program very simple reading of data from a serial port and saving it to a text file. Before recording starts, I call the function open/create/replace file, then I start reading the port, and I run the function "Write to a text file" whenever I get a certain number of bytes from the serial port. Everything works fine if I use the program as planned, I press the Start button to start the recording of data and then press the stop button to stop the recording, who runs then the function "close file". I get a well recorded transcribed text file and all is right with the world.
This application is intended to save the data for hours unattended, if I want her to be robust for a power failure. If I pulled the power so that the data connects, I always get the file on the hard drive, but is 0 bytes is no in. It seems that if I don't run the IA function to "close the file" nothing is saved. I am confused because I thought the closing of the record vi relases only the file of labview control and don't actually nothing to write to the file. Anyone have any ideas on what is wrong?
I'll post photos of the code, but its on a machine of lab that is not connected to the internet.
Discover the function Flush file in the Advanced queue Functions menu. Following is the help file for this entry:
Writes all buffers of the file identified by refnum the disk and update the directory of the file associated with refnumentry.
The file remains open and refnum remains valid. Data written to a file often reside in a buffer until the buffer fills, or until you close the file. This function forces the operating system to write data from the buffer to the file.

Hello
I want to write data to a text file. Don't ask me why, I have to use the vi 'Write in the text file' and not 'write in a measurement file. Everyone do in my office.
The point is that when I use the vi, the file is always overwritten, if I want to add data in the same file. See attachment for a view of my program. Obviouly, I'm trying to find an option in the property, but no... I sent the vi outside the lopp, but it does not work
Oddly, it works very well with Labview 2009 but not Labview 2010
Someone has an idea?
Thank you for all
See exhibit attached - open the file, move it to the end, write the text, close the file.
You can also write at the beginning of the file, or to jobs in the middle.
