The problem is in the delimiters in your text file. By default, Read From Spreadsheet File.vi expects a tab delimited file. You can specify a delimiter (like a space), but Read From Spreadsheet File.vi has a problem with repeated delimiters: if you specify a single space as a delimiter and Read From Spreadsheet File.vi finds two spaces back-to-back, it stops reading that line. Your file (as I got it from your earlier post) is delimited by 4 spaces.
Here are some of your choices to fix your problem.
1. Change the source file to a tab delimited file. Your VI will then run as is.
2. Change the source file to be delimited by a single space (rather than 4), then wire a string constant containing one space to the delimiter input of Read From Spreadsheet File.vi.
3. Wire a string constant containing 4 spaces to the delimiter input of Read From Spreadsheet File.vi. Then your text file will run as is.
Depending on where your text file comes from (see more comments below), I'd vote for choice 1: a tab delimited text file. It's the most common text output of spreadsheet programs.
Comments for choices 1 and 2: Where does the text file come from? Is it automatically generated or manually generated? Will it be generated multiple times or just once? If it's manually generated or generated just once, you can use any text editor to change 4 spaces to a tab or to a single space. Note: if you want to change it to a tab delimited file, you can't enter a tab directly into a box in the search & replace dialog of many programs like notepad, but you can do a cut and paste. Before you start your search and replace (just in the text window of the editor), press tab. A tab character will be entered. Press Shift-LeftArrow (not Backspace) to highlight the tab character. Press Ctrl-X to cut the tab character. Start your search and replace (Ctrl-H in notepad in Windows 2000). Click into the Find What box. Enter four spaces. Click into the Replace With box. Press Ctrl-V to paste the tab character. And another thing: older versions of notepad don't have search and replace. Use any editor or word processor that does.

Non-Blocking call to read the Keyboard

does anyone know how to make a JAVA program make a non-blocking call to read the keyboard? eg. write a program which generates prime number until a keyboard key is pressed.

if you use a gui you can use keyListener
Would work only if your gui elements have focus right now.

I want to make the keyboards numerical keys shortcuts for buttons.

I want to make the keyboards numerical keys shortcuts for buttons, without a modifier key is this possible ? e.g. press '1' on the keyboard button 1 is pressed on the GUI.

The number keys are not valid hot keys for our controls. The easiest workaround would be to use fhe F keys instead (F1 for button 1, etc.) However, if you are set on the number keys you could implement this with a panel callback. You could have a panel callback that monitors all keypress events and then, depending on the key pressed, calls the code that would be called with a button press of the button for that key.

I want to read the settings (time/div,Volt/div,delay,etc...)from a waveform that is saved into a memory register of a FLUKE PM3394A Combiscope.

Dear all,
I am writing a labview application for a Fluke PM3394A Combiscope. I want to read the settings (time/div,Volt/div,delay,etc...)from a waveform that is saved into a memory register. Can somebody help me on this? The Labview driver library I found on NI.com doesn't support this.
Greetings
Davy

Unless you've used some sort of "auto-setup" for the scope, all of the settings are what your program commands the scope to use. Once you've acquired a waveform, typically all that is contained is the raw data. If you need the settings later in the program, you'll have to save them by putting them into a shift register/local variable/plain old wire. If you do use an "auto-setup" (I don't remember if the scope has this feature) and the driver has no query functions, then you'll probably have to write your own. These are usually pretty simple to do and are usually similar to the settings commands with the addition of a "?" at the end. For example, if the command to set coupling of channel 1 is ":INP 1:COU AC", then to query it the command might be "INP 1:COU?"
and you would do a read and get "AC". The instrument programming manual should explain all of the command/query syntax.

You can't. (Fonts increase in size like everything else, not in height alone).

Ibooks is the program with which you read ibooks.
Not sure what the issue is.
Please explain.

else
set_timer (tm_id, 1000, REPEAT);

I want to read a log file which is created while runnning shell script line by line
dynamically
Above code is reading the log filebut all the lines are shown at once.
I have to display
each line on the text item
and the next line line by line
Can anyone help me how to achieve this.
Thanks,
in advance

In when-button-pressed trigger
I have called a shell script on application server using host command
HOST('Path of script',NO_SCREEN);
Shell script writes some set of statements to log file on application server
Problem is to read the log file on to the multiline text item each line simultaneosly
while running the script.
Below is the procedure i have written to achieve this but below code is writing all the lines at once
after entire complete execution of shell script.
for example
shell script writes tolog file:
1. 'Loading of tables';
then loads the data
2. 'emailing data';
3. ...
4. ...
Below code writes
all the 4 lines at once
I want to see in frontend what is going on while running the script
by reading the log file data line by line
WHEN-BUTTON-PRESSED
tm_id := FIND_TIMER('LOG_READING_TIMER');
If Id_Null(tm_id)
then
tm_id := create_timer('LOG_READING_TIMER', 1000, REPEAT);
else
set_timer (tm_id, 1000, REPEAT);
end if;
/* executed the shell script on application server */
host(v_command,no_screen);
WHEN-TIMER-EXPIRED
and used below code for reading a file in when timer expired
DECLARE
v_file_name := '/home/log.txt' /* log created during running shell script */
BEGIN
v_infile := Text_IO.Fopen(v_file_name , 'r');
loop
Text_IO.Get_Line(v_infile,v_linebuf);
:CONTROL.item:= :CONTROL.item||v_linebuf||chr(10);
end loop;
WHEN no_data_found THEN
Text_IO.Fclose(v_infile);
delete_timer('LOG_TIMER');
END
While running the script on application server
I want to see the data from log file simulataneously on to the form when the data is written on to the log file
Please let me know if you need more details.

Gif - file help: i don't want to read the gif each time from the file.....

Hello there guys,
i'm making a game and therefor i need to read a gif file like 20 times.
i don't want my program to read the gif each time from the file, but only once.
so i load it into an image or something?
cuz opening the gif 20 times from my hard disk is a lot of time loss....
opening it once and store it is much more efficient
thx in advance
plz help me out, cuz i don't really know how to do it.
(in Delphi it's easy, but Java......)
greetz,
SpeciesXX
Ramon Ribbe

yes, it works, i used this code, thx man
void button1_ActionPerformed(java.awt.event.ActionEvent event)
          ImageIcon image = new ImageIcon("f:/a.gif");
          JLabel label = new JLabel();
          label.setIcon(image);
          this.getContentPane().add(label);
          label.setBounds(10,10,100,100);
and there i see my image :-)
but 1 more thing, should i display all those blocks (images) on an applet, or should i use something else? (like what??)
a sort of frame?
because later on i have the field where all the blocks are in, and i have an area surrounding it, displaying all kinda information about the game, like how many lives remaining....
can i put 2 applets in eachother? like applet1 is the parent of applet2?
or should i use something else?
plz help me, cuz java is kinda new to me i see....
in delphi i just used 2 forms, form 1 with the blocks, form2 with the rest of info, and also being the parent of form1
thx again, soon i can help ya guys too, i hope..
(im learning java at school, but way too slow and to ez)

I want to read the content of a text file dropped in a watched folder into a string variable

I have a workbench process with 2 variable.
inDoc (DataType=Document/input/required)
outStr (DataType = String/output)
The document being passed to the workflow is a text file with 4 lines of text in it. when the text file is dropped into the watched folder, it will be assigned to the inDoc parameter in the workflow.
My workflow needs to extract the 4 lines of text and write it into a string (outStr).
Id like to use the FileUtilsService.ReadString service but i can't since its input parameter is the file path. When i do, i get the following error...

at com.adobe.livecycle.fileutils.FileUtilsService.readDocument(FileUtilsService.java:363)
which is what i expected...
I've also tried with the Script.executeScript to call some java code but im not too strong in java and in all the examples i find, the file pointer requires a file path.
import java.io.*;
FileInputStream f = new FileInputStream(patExecContext.getProcessDataValue("/process_data/inDoc"));
OR
File f = new File(patExecContext.getProcessDataValue("/process_data/inDoc"));
OR
File f = patExecContext.getProcessDataValue("/process_data/inDoc");
Any clue how to resolve my problem?

Try the following code snippet to read the String content from the file recieved through watched folder endpoint.
com.adobe.idp.Document inputDoc = patExecContext.getProcessDataDocumentValue("/process_data/inDoc");
java.io.InputStream inStream = inputDoc.getInputStream();
byte[] dataBuffer = new byte[inStream.available()];
inStream.read(dataBuffer);
String strData = new String(dataBuffer);
patExecContext.setProcessDataStringValue("/process_data/outStr",strData);
The code is not tested, hence if you find any mistakes, correct and test the functionality.

I have a neslab chiller and want to read the temperature by sending ASCII characters and graph the results, any advice?

I am having difficulty having the chiller recognize (RT[CR]) which is the signal recognized by the chiller to read the temperature. The signal that is returned is (xxx.xx[CR]) which is the temperature. I am attempting to be able to read the temperature and graph this vs time and possibly be able to change the setpoint as well from the UIR.

I agree with Randy that Hyperterminal is a good starting point to test cabling and communication.
In your program, be careful to serial port initialization (how to set baud rate, parity, data bits and stop bits depends on the language used) and to termination character ([CR] means Carriage return: if you are usng CVI it DOESN'T add CR to the message unless you esplicitly put it in).
Another interesting point is the time the instrument takes to respond to the message: it can vary from message to message and is usually described in the instrument's documentation. If you test for a shorter time, you catch a false 'no response'. You could make a while loop and test in it the number of bytes received, then decide whether to end the loop for timeout or answer recei

How to read the keyboard of a smart phone with labview mobile?

The subject about says it all. I have an HTC phone with keyboard that is running WM 6.1. Using key events I can catch the left and righ soft keys and the left-right-up-down cursor movements, but it doesn't see the keyboard.
Mike...
PS: as a side note... given that Microsoft has signalled that it is pretty much abandoning the WM platform due tio lack of acceptance, I wonder what NI is going to do for mobile applications?

I want to read the values of the inside accelerometer on Kinect for Windows v2 sensor.

I had used the inside accelorometer on Kinect for Windows v1. So I want to use it for Kinect for Windows v2 application. However I can't find any function or method on Kinect for Windows SDK v2.0. But it is near the Ir camera of K4W v2. I found the Kionix
chip. Do you have any plan to access this chip?

I just went through the slides of "Programming Kinect for Windows v2 Jump Start" of the MS Virtual Academy, and in slide #11 of slide deck #07 (Advanced Topics: Skeletal Tracking and Depth Filtering,
http://www.microsoftvirtualacademy.com/training-courses/programming-kinect-for-windows-v2-jump-start), it says:
Align the y-axis to gravity
–Tilt correct with
FloorClipPlane.xyz
•Falls back to accelerometer when no floor is found
•Rotate
scene such that “up” is (0,1,0)
So, just to make sure I understand, you are saying that the information provided in the slide deck (and in the video) is erroneous and we cannot access the accelerometer info?
