  You mentioned you want to only read text files.

  If you are referring to a specific set of extensions, you can filter on this basis.

  ex: you want to only read .txt files, you can add an if condition as below:

            if(textfiles.getName().endsWith(".txt")) {
                // Add your code here
            }

• testimonial widget that reads the text file

  Is there someone who makes a testimonial widget that can read a text file? I am considering this is a block for customer testimonials that can read a file of say 50 different clients we wil cut and paste from various places, so that there is always a fresh review illustrated.

  Themes of Muse has some text widgets: one as a ticker-tape driveand displays a (small) number of citations. But none will allow you to modify a file of text outside the Muse of let's say 50 paragraphs and read on the page, one by one, in order.

  There are a lot of scripts to do exactly what you want, like this: alternating Message text box . JavaScriptSource, and many others, just Google: "alternating rotation script of text message". But are you able to manage scripts and HTML codes in Muse ? Maybe some useful script Wizard can cook a place for you or modify an existing one, provide you a text template file and help hair and be implemented in Muse page.

  Don't let them not to edit your output !

  Ask them to help you with a method to ensure within the Muse:

  1. adds a style and script in the header of page (see Page Properties)

  2 Insert the HTML code on the page (under the object menu)

  3 attach the text file on the site (hyperlink, link to the file)

  So, you can change the text file and download all changes with Muse.

  Hope this helps?

• How to read a text file with line breaks

  Hello

  I'm reading a text file in a textFrame.  We read in, but does not include line breaks is just a big long line of text.  I use the following code to read the file.  I tried to insert a \n character after each readln() but that has not helped.  I also tried to create a variable that the readln() was crammed in before setting the textFrame.contents variable, but which does not work either. I'm puzzled. Any help would be appreciated, thanks.

  While (! notesDoc.eof) {}

  noteTextRef.contents += notesDoc.readln ();
  }

• Not able to read the text file several times - Bug?

  I open the Refnum to a text file by starting my software and I'll keep the file open until the software works. I read a text file when an event occurs. The problem that I'm facing here is when I read that the file 1st time Lily can't read the text of the file but when I read it to get even empty string only. Could someone help me understand why this happens.

  

  A race condition?  What's with the two readings at the same time?  Keep the opened file is not a problem, but remember that there is a file pointer.  If you read empty strings, it's probably because you're at the end of the file.  Use Set leader VI to set Position is for the beginning of the file.

• Read a text file

  I have hopefully a quick question.

  Why doesn't the reading of text file in this example?

  Thank you

  

  When you write to a text file, LabVIEW keep a pointer with the reference so that you have the file open. So after you write 'test' in the file, your new pointer is now at location 4. When you read on, it reads pointer 4 and on.

  Use the function set the file Position in the palette advanced to read the 0 position.

  What can you tell me? Thank you

  GET_FILE_NAME will try to open a 'Open file' dialog box on the server, which obviously cannot happen. If you want to use this type of behavior, you must use the function CLIENT_GET_FILE_NAME and WebUtil. Example:

       filename := CLIENT_GET_FILE_NAME('C:\', File_Filter=> 'Text Files (*.txt)|*.txt|All Files (*.*)|*.*|', dialog_type=> OPEN_FILE);

  More information here:

  In addition, it seems that you try to use a mapped drive ('U'). Although this can be made to work, it is not recommended and in some cases is not supported. If you need access to remote files, you must use another mechanism to put the file on the local computer before handling.

• Not able to read a text file or binary

  I am reading in a file text or binary, as shown in the Blackberry "how - adds an application of plain text or binary files"

  http://www.BlackBerry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800332/800620/How_To _...

  I use Eclipse 3.4.2 I implemented a project of Blackberry with the following structure:

  Test1 (project name)

  -src (folder)

  |   + com.name.xxx

  |   + com.name.yyy

  |            Test1.Java

  + NET_RIM_BLACKBERRY

  |

  -test

  I'm reading in the test file is at the level of the main project folder.  For example, the Test1.jdp file is located in the folder of the main project and the test file (text file or binary).  I am trying to access the file using the line of code below:

  Class classs = Class.forName(this.getClass().getName());
  
  InputStream is = classs.getResourceAsStream("/test");
  

  The getResourceAsStream indicates that the file will be in the same location as the location of the Test1.jdp file if the bar oblique is in front of the name of the file, or that it will look in the source for the main class file.  When I have the slash I get error

  CAFETERIA: could not find the test file

  I tried several different attempt to get to the CAFETERIA to find the file, but I'm running out of ideas and I would appreciate someone else's ideas on what to try.

  Thank you

  Thank you klyubin and stef

  I found a solution that works for me with Eclipse plug-ins, JDE.

  First, the example of Blackberry in the how-to (see original thread number) with test as file is named simply 'test '.  This does not work for me at all in Eclipse.  I gave up to place the file in the folder of the project Eclipse (main folder) and placed in the src folder, which of course gives a compile error because is not a Java file, and of course when using file name in my java code I changed the code correctly as in the first line that follows :

  
  // this will look in the source folder of the class // that myClass refers tois = myClass.getResourceAsStream("test.txt");
  
  // this is supposed to refer to a file called 'test' // in the source folder of the class that myClass refers to // but apparently for Eclipse it must have a .txt extension// as in the above exampleis = myClass.getResourceAsStream("test");
  
  // this is supposed to refer to a file called 'test' // in the main project folder but not apparenlty for Eclipseis = myClass.getResourceAsStream("/test");
  
  // this is supposed to refer to a file called 'test.txt' // in the main project folder but not apparenlty for Eclipseis = myClass.getResourceAsStream("/test.txt");             } 
  

  Note: I was also getting the error message when I place the file named "test" in the src below directory.  I managed to get rid of this error message by configuring the path building (similar to deleting the file of the JDP file including klyubin suggested above for Blackberry JDE ordinary rather than the plugin Eclipse) to remove the file 'test' for compiling so I would not get the compile error.

  However, this was not my main problem - if you name the file test.txt and place it in the src directory you do not get this error I believe.

  Errors during construction

  Errors running builder "Blackberry resources Builder" on the project...

  Could not compile files

  java.io.FileNotFoundException: C:\path to the file I had added in the directory\.rrh of the source (or some truncation of the file name .rrh - for example te.rrh)

  Finally, I have checked the jar (as klyubin suggested) file that is created when I place the file 'test' or 'test.txt' in my Eclipse project main folder.  The jar file did not contain the name file and so when I run in the Simulator, the file is not found.  Even when I put the file in the jar (main directory) myself the Simulator still could not find the file.   When I placed the test.txt file in my directory src the jar resulting file contains the file named and the Simulator can find the file ok.

  So, it seems to me that for the plug-in Eclipse JDE contextual explanation of the method getResourceAsStream does not apply as described at this time.

  getResourceAsStream

  public InputStream getResourceAsStream(String name)
  

  Looking for a resource with a given name. This method returns null if no resource with this name is found. The rules looking for resources associated with a given class are specific profile. RIM implementation notes: this method searches the resource from the directory in which the current JDP project file is located. By default, it is assumed that this JDP file resides in the parent directory of the package of the current project space. Thus, the package space tree (for example, com/rim/PackageName) is added to name so that the search begins from this space package, that is, in the source directory of the current project. However, if the current JDP project file does not lie in its presumed location, the behavior above prevent the resource located. In this case, the user must add a slash (/) in the name of the resource before calling getResourceAsStream. This treats the name as an absolute path, which is compared to a tree whose root is the location of the JDP file. Parameters: name - name of the desired resource Returns: a java.io.InputStream object. Since: JDK1.1

  If Alain klyubin (or someone else) can enlighten us more on why the file should be named *.txt to find the file in the source directory, which can be useful to me and others in the future.  My real goal is to read in an image file named *.jpeg.  We'll see how it goes.

  And thank you klyubin for the suggested code change which I had also found in another thread...

  // this was more than what was necessary//Class myClass = Class.forName(this.getClass().getName());
  
  // this is simpler  Class myClass = this.getClass();
  

  And so many other Eclipse users who try to follow the Blackberry How To - add a text or a binary file in an application, do not forget to consult the file name in your code java as in the examples that I gave above.

• Reading a text file and store it in a table, guard return 0.

  Hello, I have an application where I need to read the speed and rate of a text file. For this application, I use a myRIO NEITHER and I want to save the text file on the drive the myRIO aboard in the tmp folder. I simplified my request to isolate the possible problem and I will attach a sample text file and my VI is used.

  Overview:

  I use a myRIO project because in my real application I myRIO VI of PWM and encoder. I noticed that my problem goes away when just open the main VI and run the application in LabView. My problem then that chairs the VI on a project myRIO folder.

  To address the issue:

  My question is, when running the VI of the hand of a project myRIO folder everything works as it is supposed to, but when you open the text file in my Subvi, it returns 0, as if nothing is in the text file. Now if I open the VI outside myRIO se project file it works just assumed that when X = 1, it opens the text file written data in a table and then close the text file. I can't understand why he reads nothing in the text file executing the main VI of a project of myRIO and when I use run to highlight one can see it opens the text file and then returns nothing. The text "test" file must be placed in the tmp folder on board the myRIO to validate my way.

  Is there a way to fix this?

  I assume because I use a myRIO project I can't access the file text, or because of how LabView?

  Any help is appreciated, thanks in advance!

  You don't have your son wired error upward.  You're files showing error functions?

  What context are you running VI when you are within the project and what context from outside the project?

  My suspicion is that in one case, you run on your PC, the other on the cRIO.  Your file exists only on one device or the other.  And also that when you change your PC for the cRIO, your file path must change.  It's very strange that your watch VI access you the disk R:\.  I bet that the R:\ car n does not exist on your cRIO.

• While loop with reading of text file - calendar of events in a given period

  Hello world.

  I created a program that if serial interface via a port to a syringe push in my lab. Currently, the program reads in a text file-flow rate values and sends them to the pump, one by one, through various commands. I need to ensure that whenever a new flow rate value is sent to the pump, it does in a specific/hard time for a while. I.e. every 0.1 seconds, changes in flow rate and must are active until the next period. I tried to use a timed loop and I think I've succeeded, but it hogs system resources, so I was wondering if there was a way to do it using the number of cycles or something of this nature. I just started using LabView, so I'm slowly getting the hang of it (easy when you watch my VI!)

  See attached VI. I took orders from serial port and have instead orders display in an indicator. The nested and densely populated while loop contains the commands that need to be completed/last during the period (like 0.1 second).

  Thank you for your time and help!

  Hi, you should read some introductory material on LabVIEW to down the idea of the stream.

  Basically, the data flow in the wires from left to right, and any node will not work until it has reached all of his contributions.

  The thread of the error is the best way to run data streams.

  ***

  In your VI I use data wires, their execution through structures, and forcing the structures to run in the sequence.  Using a structure of sequence you mentioned in your next post will force the two scripts to execute in the order of (the only one we discussed to be in race condition.)

  Similarly, for brevity, I would wrap the EMO and she is business structure in a single sequence and force it to run last using stream.  In this way the user has the most possible time to decide to hit the EMO before she is called by the application.  As it is now, it most likely is interviewed at the beginning of the loop, so if it's the exchange value you won't see results until the next loop.

  When running in execution of highlight you see the order of data flow, but that is not guaranteed to be the same for a normal performance, where the use of the data stream.

  ***

  The counter tick account ms up to a very large number and then "says" reset and start counting again.  I know you want to START the loop as close to every 10 ms.  Yes, using data flow, take the number of cycles first, perform actions, then return the number of cycles.   The second time of the tick read that you are in a nested loop that does not stop until you get 10 or more difference on the number of cycles.

  And, on the off chance that you must achieve "return" on the tick counter comes stops the nested loop then move.  (if the second measurement is less than the first, then the tick counter handed.  If you miss this situation while you'd have to wait a long time for the condition of the difference > 10 in the reunion, basically locked in the loop.

  ***

  You could put the EMO sequence, we have seen, in line with data streams.  Before or after the second control of ticks will not make much difference in terms of 10ms.  I would put it after checking the tick, again give the user more time to hit the EMO if necessary.

  ***

  I put in a queue for the stream error and removed the other stuff.

• How to read a text file that is longer than 65536 lines and write the data to a spreadsheet Excel and the data to write in a new column, once exhausted 65536 cells in a column?

  I have data to the basic generic text file format that must be converted into Excel spreadsheet format.  The data are much longer than 65536 rows and in my code, I was not able to find a way to see the data in the next column.  Currently, the conversion is done manually and generates an Excel file which has a total of 30-40 complete columns of data.  Any suggestions would be greatly appreciated.

  Thank you

  Here is a possible solution to the (potential) problem. Convert an array of strings and erase the data before writing to the file
