Open a txt file in a real time PXI target

I want to open and read a txt file when targeting to a PXI, running a real time OS. The file is saved in a specific directory of the real time machine. When I run the typical Labview (version 7.1) examples there is alwasys an error message.

Hi Matt,
I hope you're doing well. To be able to open files on the host from the RT target or vice-versa, you most likely will need to FTP the files back and forth between the two. You need to have the files local on either machine to be able to edit or view them, and FTP is the simplest way to do so. You can connect to your RT target via any standard FTP utility as discussed in this KnowledgeBase article. I hope this is helpful. Let us know if you have any additional questions though.

How to write a code for open new txt file in swing

hai all,
now i do one project in java.that project's GUI is Swing. But i don't known swing (basic).So how to write a code for open new txt file and "Open window " in menu item on swing.that means when i click the "New" on menu that time open a new txt file. open also like that type.
plz give me that code ! very urgent
Advance Thanks !
RSK

Swing Tutorial:
http://java.sun.com/docs/books/tutorial/uiswing/index.html
Since you don't know the basic of swing read the tutorial, it is for your own good because it is useless if we provide you with a code you don't even understand and how it works.
If you want a menu read the tutorial about using menus and for opening a file read using JFileChooser.
note: don't use the word urgent because it implies that your problem is more important than others.

Open all TXT files in Ultraedit

Currently from the below code I am able to open a new empty file in ultraedit. But I need to open all *.txt files from a particular directory in ultraedit. Could anyone please help me with this.
private void ueditButActionPerformed(java.awt.event.ActionEvent evt)
     java.awt.EventQueue.invokeLater(new Runnable()
          public void run()
               try
                    Process procViewEd =Runtime.getRuntime().exec("C:\\Program Files\\UltraEdit\\UEDIT32.EXE ");
               catch(IOException ioe)
                    System.out.println(ioe.getMessage());
} For instance, when I click on ueditBut, all the txt files inside the path c:\temp should open in ultraedit.

As an example, this code opens all of the .java files in the current directory using notepad:import java.io.*;
public class Test {
    public static void main (String... parameters) throws IOException {
        File currentDir = new File (".");
        File[] javaFiles = currentDir.listFiles (new FilenameFilter () {
            public boolean accept (File parent, String filename) {
                return filename.endsWith (".java");
        for (File javaFile: javaFiles) {
            Runtime.getRuntime ().exec (String.format ("cmd /c notepad %s", javaFile.getAbsolutePath ()));
}

I want to open a txt file and output data through an AO-using DAQmx for PXI

I have a PXI running a 8145RT CPU. I have a PX6040E Multifunction DAQ card installed in the PXI. I want to program an application where I open a txt file (existing in one of the the RT machines' folders), read the first row, and output its data through an AO channel. The drivers I should use is DAQmx v7.1, and the Labview RT v.7
Any idea?

What exactly are you having problems with? Reading a text file can be done a number of ways. Look at the File I/O palette and check out Read Lines From File or Read Characters From File. There are string to number conversion functions on the string palette (i.e. Scan From String). There are also numberous shipping examples on using DAQmx for analog out. If you have a specific problem or question, please post back with additional details.

Error "cannot load request real time data targets" for new cube in BI 7.

Hi All,
WE have recently upgarded our SCM system from 4.1 to SCM 7.0 which incorporated BI 7.0.
I am using BI 7.0 for first time and ahve the following issue:
I ceated a new infocube and data source of flat file and succesfully created transformation, and Data Transfer Process. Everything looked fine. I added flat file and checked preview and could see data. Now when I start job to load data in infocube the follwing error is shown "cannot load request real time data targets".
I checked cube type in setting in infcune is shows as Standard. When I doube clicked on error the following message showed up
You are trying to load data into a real-time InfoCube using a DTP.
This is only possible if the correct load settings have been defined for the InfoCube.
Procedure
In the object tree of the Data Warehousing Workbench, call Load Behavior of Real-Time InfoCube from the context menu of the InfoCube. Switch load behavior to Transactional InfoCube can be loaded; planning not allowed.
I did not understand what it is meant and how to set changes. Can someone advice and follow me through.
Thanks
KV

Hi Kverma,
Real-time InfoCubes can be filled with data using two different methods: using the transaction for entering planning data, and using BI staging, whereby planning data cannot be loaded simultaneously. With Real time cube you can select the method you want to use for update as
Real Time data Target can be loaded With Data; Planning not allowed &
Real Time data Target can be Planned; Data loading not allowed
You can change this behaviour by right clicking on cube and selecting Change real time load behaviour and select first option. You will be able to load the data then

Gigabit ehternet card in real time PXI chassis

I was reading document # DZ52103_US about general real-time
information. This document states that plug in ethernet, serial, and
GPIB cards are not supported for real-time I/O operations. I want to
use a plug in PXI gigabit ethernet card to transfer data from my real
time PXI chassis to a host laptop computer. Can this be done?

Currently, the only PXI ethernet controllers supported in LabVIEW Real-Time are the PXI-8211 and the PXI-8212. These are not Gigabit cards. This information is documented in the following link and will be updated as ethernet device support in LabVIEW Real-Time changes.
If you have any further questions, please post a reply.

Opening a .txt file from an application

I have an application that extends JFrame. There is a JButton that I want to use to open a file called
"Instructions.txt."
and the path to the file is
"E:\CM0112\Code\Instructions.txt".
I want to open this file using TextPad, I have tried the code
Runtime.getRuntime.().exec()but I keep getting compile errors. Any hints would be greatly appreciated.

try this code
public class Open
public static void main(String[] args)
     String line;
     EasyReader inFile = new EasyReader("instructions.txt")
     if(inFile.bad())
        System.out.println(" *** Can't Open instructions.txt *** ");
        System.exit(1);
     while((line = inFile.readLine()) != null)
       //implement your own code, each time loop executes
       //line is the next line in the file until it is null.
Go to www.rfrank.net/cs-labs/1400-tasmania/EasyReader.java to find EasyReader.java

Defect: Sometimes opened sql/txt files are unreadable in worksheet.

I haven't pinpointed the exact sequence of events yet. Sorry.
I work on two different machines. One: 64bit running Vista. Two: 32bit running XP.
They have the same fonts and operating system languages.
I keep a set of files I'm working on on a usb stick (which appears to be working perfectly).
Sometimes, but not always, when I open up a one of those files on the key, it shows up as square-box gibberish in the sql worksheet window.
I can open the same file with notepad just fine, and paste the contents into the same sql worksheet just fine.
But it's a darned nuisance, not to mention an opportunity to overwrite my work if I forget to close the open file in notepad and save it later.

I've had a few moments to try to track down more info on this problem.
I work on a 64bit vista machine at work and a 32bit windows xp machine at home.
I'm at home, so I'll post what I discovered here, and then post what happens on the 64bit when I get to work tomorrow.
All the files I'm discussing have only the standard ascii characters in them.
Both machines have the same fonts and font setup, and the same OS language. I do not believe this is a font or language issue.
I believe it may be an encoding issue.
I opened up a .txt file with sql developer. It happened to work fine this time.
I opened up the same .txt file with notepad, and saved it to a new .sql extension. It opened fine with sql developer.
I opened up the original .txt file with notepad and saved it to a new .txt filename and chose the unicode encoding instead of the ansi encoding that notepad was defaulting to. I also used notepad to save the file to another .txt file and chose a utf-8 encoding for it.
I opened up the unicode encoding file using sql developer and got gibberish. Upon closer inspection, I could actually read the code in the file, but each character had a box between it. I'll use [] to represent a box. So, my first line looked like this: [] [] []b[]e[]g[]i[]n[].
I opened up the utf encoding file using sql developer and got some gibberish, but most of the file looked fine.
My environment setting had UTF-8 as a setting.
I changed the environment setting to UTF_16, and re-opened the files.
The file saved as unicode is now readable and the other files are now complete gibberish.
I'm guessing that my work machine has a different default encoding scheme at the operating system level, because I believe both are set up with the same settings inside sql developer. (I used the same written instructions for both.)
I'll post what I find at work tomorrow.
If this turns out to be correct, it would be nice if sql developer automatically checked the encoding of the file when it was loaded and acted accordingly. That appears to be a possible course of action, because when I open up each of the encoded files in notepad, it (a) displays each of them correctly automatically and (b) when I do a save as, it shows the encoding the file was last saved in as the default value.

How can I display a .csv file as a real time waveform using labview

Hi folks.
As stated, Im looking to display a .CSV file (obtained via RS-232, example; 100,101,102,102,102,103...) as a waveform in real-time. What is the best way to approach this? Im thinking LabVIEW. I have version 7.1 but am not really experienced in using it. I'll give anything a go though. Also, I have Visual Studio 2005, so I was thinking VB???
Thanks in advance!
Simon.

Two users opened the same file at the same time with file on Win2K Server

I just had a problem with a file that could not be saved. After a little investigation I discovered that two users had the same file open at the same time. This is with both users using InDesign CS2 and saving to a Windows 2000 Server. Any ideas how this even happened? The only thing I can think of is if they both opened the file at the exact same time but even that I doubt. I guess the more likely possibility is that the user on 10.5 (which we have had a lot of problems with, it's hard to tell how many of them are CS3 problems (yes CS3) and how many are Windows 2003 Server problems) had InDesign CS2 flake out and not tell her the file was open. Has anybody else seen this? The other user was using 10.4. Both computers have the most recent updates for the OS and for their various adobe products.

I have videos on mov file and my quick time player does not play them.
The MOV file container is the generic QT file container. Any audio and video data compatible with the computer system used to create the file can be placed in the MOV file container. Unfortunate, other systems cannot play the file unless they too are configured with the same components as those used to create the file. The normal procedure here is to use the Finder "Info" or alternative media play "Inspector" window to determine what codecs were used to create the original file and, if they are available for your Mac, install them on your system for playback use. Also be advised that some "legacy" codecs may require playback in the QT 7 Player for proper QT support.
I opened with other players, there is no sound. Then I opened the same file on my windows 7, it plays perfectly with the sound and everything? What is the problem?
This would indicate these players either access your QT codec component configuration which does not include the required codec or the app has its own built-in codec support which does not include the required audio codec but you Windows 7 media player is configured with the required codec support. This may incidate the use of a really old codecs that may or may not be available/supported on a Mac any longer.

Is there a way to create a button on the front panel that would automatically open the txt file data is being stored to?

I am saving data read from FieldPoint to a .txt file. Is there a way to create a button on the front panel so that when the user pushes this button it automatically opens the .txt folder in notepad? I want to bypass the user having to find the file in the computer in order to open it.

Hi jem,
I suggest that you break this up into three seperate questions and re-post to this list. That way you get more ideas from others that may have better insites than myself.
Re:the sysexec
The Sysexec will allow you to execute a dos command. This is the equivalent of going to
Start>>>Run
What you should do is find the proper DOS command sysntax that is required to open a text file in notepad or your favorite editor. Once you know what a good DOS command is, you should pass that string to the Sysexec.VI. The Sysexec has an input that allows you to choose if the code waits for the command to complete or if it should just start the program and let it run in the background. Sysexec will open its own window to run the command you speci

Getting extra line after each record when opening a .txt file in excel

Hi All,
I have developed a program which downloads a file at application server.
each record of file is 500 characters long & have CRLF at end.
the file looks fine when opened in .txt format.
however when i download it from application server to presentation server (using function "download to my computer"), & at presentation when i try to open it in excel format, it shows a blank line after every record.
i don't want this blank line to appear if i download it & open it in excel.
the file record is declared as char500 type.
Please suggest how to deal with this.
thanks in advance.
Regards,
Puja.

Hi Puja,
Check the file in the application server whether it has any gaps between the lines.
Or else as you said if the file looks ok in .txt format, download the file in .txt and open the same file in excel (i.e. open with excel)
Hope this sloves your problem.
Regards,
SB.

File lock in real time job

Hi All,
I encountered an file lock error when creating a real time job.
After a dataflow, I have a script to move the processed file to archive folder. (e.g. move c:\source\order.xml c:\archive). When I test run it, I received a 50306 error. It saids "The process cannot access the file because it is being used by another process. 0 file(s) moved.". However, the df and script were running OK in batch job. Also, I can move the files manually after the job failed. Can anyone help me with that? Is it something to do with the setting of realtime services?
Many thanks!
Knight

hi,
Not sure but you can check in sm12 if there is any lock entry, if so than manually delete and than check again.
