Write to the file in Question

I do modeling experimental with a VI that many members of this Council greatly helped me go.  Part of this modelling is the creation of a periodic function.  I accomplished this by using 30 value entries 'Y' and a frequency to create sort of a 'function of unit', or basically, a period with a value of function, with a maximum amplitude of 1, while it is conveniently set on the scale.

What I find is that it'd save these 'functions of the device' as well as their corresponding amplitude and frequency of file, that I cannot laod later in the program.  So, I need to write data to a file, (30 pairs of doubles, with 2 independent double rooms) and then have the opportunity to browse through all my saved both functions load the desired one.

I used the express vi 'Write in a file as' before, but that seems to be a clumsy way to do it.  I then played with the various «write to...» "vi is available.

For a relatively small set like that, is it interesting to a file rather than another type?  Of course, much data could go directly into an excel file, even if it should be reformatted to strings to store in the text.  I have little or no experience with bianary files.

All file types are easier to load then go?

And is it possible to have the (previously saved) functions available and selectable ring of menu, or will it prompt the user?

That said, I'm looking for some general advice on the region.  I've read all the help files associated with and read some threads on the specific issue.  But being new, I'd like to hear how you professionals would approach this function.

My current code is attached.

  • Write to the file in Question Spreasheet

    Hi guys. In fact, I have a few questions about the most effective way to do a number of things. This VI aims to collect a tension all the seconds so as determined by the user and then draw the voltage vs the time it was taken. I also want to save all these in a text file.

    Currently, it works pretty well, but I don't know if graphs of my functions as I have (drop voltage and time values in a table and using Graph xy generation with the berries as inputs) are the best way to do it. Because I take only data each max ~ 5 seconds table size will never become a problem? I could run the program for a period of ~ 24 hours is 17280 values in the table at the end of the day.

    I am also having a problem with the way in which the values are stored in the spreadsheet file. How I put it in place now values are added to the current file that is not a problem. However they are not separated by anything when I open the txt file, whether they are in the same column. I know I put something inbetween them such as a tab or comma for excellent to put them in different columns. What is the best way to do with the numbers? Above all, I converted the concatenated strings then a tab/comma at the end of the data point, then get it converted to a number, but it seems that there must be an easier way to do it.

    Other comments randomly on the rationalization etc. my code is appreciated

    Thank you!

    The approach of the producer consumer, I'm guessing that I would simply put the DAQ assistant in its own sequence that takes a point of data every x seconds while the representation graph/writing/etc is it's own loop. Looks like a much more viable approach.

    I wasn't suggesting to the DAQ assistant in its own sequence. Architecture of producer-consumer, the consumer is usually (but not always) a state machine. The state machine gives you much more flexibility than a rigid sequence structure.

    One last thing I wasn't very clear on the problem of delimitter. In fact, I want to insert a delimiter inbetween two tables, not just after them. So, right now, they are put into a single set. Time of tension then below it. I want a delimiter between the voltage and time so that when the file opens tension appears in a column and time appears in the next. While the file drop down a row and repeat the tension. Time. So I think I still need a way to add something to the tension or maybe insert an ascii value between them that will work as a delimmiter?

    Your problem is performing connections to the entry of table 1 d to write it in the spreadsheet file. I had spotted this when you first look at your VI. Table to build that creates the array for writing to a file in spreadsheet should have the opportunity to 'Concatenate entries"not controlled, and you should feed data to the entry in table 2D writing worksheet function.

  • Issue of table + write to the file

    Hello, I am using USB-6009 with Labview 8.5

    I searched and passed tutorial table and still confused about acquisition of data...:)

    So here's what I'm doing (simple)

    I have two tension analog (AI0 AI1) returns through the DAQ assistant

    and I would like to follow up respectively and finally want to write them in lvm format or csv format...

    Question 1.

    Can I have an example of table VI with the DAQ assistant? all the tutorials I went on

    they are only about numbers--not the dynamic data...

    I think of... convert data into DBL and reorganize somehow to each table to the graph of the monitor

    Question 2.

    so I cut the data by using the table to display the monitor, then I will add both the value of the data in table

    to write to the file? or... is it possible to write in the file directly from the Daq Assistant, write on the file VI?

    Quesetion 3.

    If so, could you tell me how this writing on a file to save the data? 1st column with odd rank-> AI0

    1st column with the same line-> A1... something like that?

    Thanks, I spent about 3 hours of that, google them, read the help of labview and helped a lot

    1. you should be able to double-click the convert to Dynamic Data and convert the waveform in a table.

    2. just connect the output of the VI DAQmx Express write it on the Express VI of LVM.

  • Error: "there was a disk error when you write to the file C\:Program files (x 86) \microsoft games\dungeon siege\resources\objects.dsres" during the installation of Dungeon Siege.

    When I try to install it it comes up with an error about 16% in the installation, saying that there is a disk error when you write to the file C\:Program files (x 86) \microsoft games\dungeon siege\resources\objects.dsres

    Any ideas?

    Hi MouseToe,

    What version of Dungeon Siege you trying to install?

    The cause of this problem could be the corrupted resource (.dsres) file or disk error. Here are some things you can do to solve the problem.

    Method 1: Run the disk check.

     

    Check the integrity of your hard disk for lost clusters and errors.

    To do this, follow the steps in this article: check a drive for errors

    Method 2: Defragment the hard disk.

    This improves the performance of your hard drive.

    Reference: improve performance by defragmenting your hard drive

    Method 3: Run the game as administrator.

    Here's how:

    (a) right click on the game configuration file.

    (b) choose 'Run as administrator'.

    Method 4: Try to install the game in a different folder or to a different drive

     

    Try to install the game in a different folder. If the computer has another hard disk, try to install the game on the other hard drive.

    Follow these steps.

    a. Insert the game disc in the drive.

    Note: Do not click on Quick Installation during installation.

    b. follow the setting menus until you see the change button.

    c. click change.

    d. in the path box, delete the existing path, and then type the following text:

    drive: \Program Files\Microsoftgame name Games\

    In this example,drive is the letter of the hard disk drive and the name of the game is the name of the game you are trying to install.

    e. click OK when finished.

    f. follow the instructions that appear on the screen to install the game.

    This should be it.

  • What makes "new queue path" to write to the File.vi worksheet? I need a better explanation than what is given.

    You are looking for assistance.

    What makes "new queue path" to write to the File.vi worksheet?  I need a better explanation than what is given.

    Thank you.

    You can call this function without wiring to a path of the input file.  If this is the case, the function prompts the user for input file using a pop up dialog box.  If a file is selected and you press OK, it is the path of the file that is out of the function as the new path of the file.  If you press the button cancel instead of OK, the "not a path" constant is the new output file pathname.  If the function is called with a wired file path entry dialog box appears, the same path of file entry becomes the new output file path.

  • collect the data to write to the file

    Hello everyone!

    I was wrong of wich pretty depressing problem my mind... for a few days. I have a VI with while the witch loop is part of the largest project... my goal is to collect data and save them to file after 1000 while loop activities... be more specific - after all done loop 1000 moves I want to write to the file, the number of strokes (in the 'Number' of an attachment photo) and the result of the value ('table') should be a kind of table (2columns 1000 lines)... I can't do more while ower loop all the VI because it allows the other VI to work... Can you suggest me sommething?

    .. .to while say you the activities of the do loop iterations?...

    Yes, it's wright, I couldn't find the wright expressin at the end of the night.

    OK I will try to write to the table line by line... I'll check up is it posible to add to an existing spradsheet of the file a line of data for 1000 times after each iteration of the loop... it might be more reliable because each iteration of the loop is device once in a 30 min, and if your PC loses power I lose all data.

    Thank you so much for the ideas!

  • Change .txt and write to the file system

    < / ns1:Record - n >


    For example the input file are < ns1:Record - 1 > appears twice and < ns1:Record - 2 > appears three times in the file.

    In the output file, I want that < ns1:Record - 1 > occurs three times and < ns1:Record - 2 > occurs four times - more initial registration amount 1

    How is it possible to do? Thank you.

    Hello

    Good to know that your problem is solved.

    Your solution to the problem (copy methods and insertAfter bpel) seems to be very well and works as planned including the edge cases. Rather than use the counters, you could use the "count" in clause () method in .

    (Ex: $Invoke1_Write_InputVariable.body / ns3:Record - 1 [count($InputVariable.body/ns3:Record-1)])

    The snippet of Java code that you plan to use works very well when the records are sorted (ascending). You could do the same thing in bpel code too, but I prefer to implement the same using the method described above.

    Hope that my updates have been useful for you.

    See you soon.

  • Rules - write to the file how each Const mean?

    I have a subroutine in my rules to write to the file.

    It contains a line indicating: Const ForReading = 1, ForWriting = 2, ForAppending = 8

    What do each of them?

    To write?
    Read?
    Add?

    I used to use Add, but he seemed to be putting items duplicated in the file everytime I ran it.

    Then, I tried writing and he gave me a single record.

    Thank you!




    Here are all of the subroutine:

    Void WriteToFile (txtStringToWrite, FName)
    On Error Resume Next
    Const ForReading = 1, ForWriting = 2, ForAppending = 8
    Dim fso, f
    Set fso = CreateObject ("Scripting.FileSystemObject")
    The value of f = fso. OpenTextFile ("C:\Hyperion\Extracts\" & FName, ForAppending, True)
    f.WriteLine txtStringToWrite
    f.Close
    On Error GoTo 0
    End Sub ' WriteToFile

    By adding the means adding the same file - the number of times you run the rule he adds in the same file.
    Write clearly means the first file and the wirte.

  • Write to the file of text formatting issues

    My apologies if I touch on a topic that is discussed elsewhere.  I have two questions, which seems to be related, I'll have to overcome the difficulties.  I date of blood collection, converting it to a temperature and then writes the timestamp, temperature, voltage, and original tension to the file.  Currently, when I write these values to the date and time of the file appear on a single line, temperature and tensions appear on the next line, and then there is a space before the pattern repeats.  In addition, before data are collected I write information in a header, and if you look at the .csv file attached, you will see that the data are that all offset a column to the left.  Any ideas how I can fix this problem?  My code is probably speaks for itself, but I really am a novice, so any general idea in the non-jargon terminology will humbly accept.  Cheers, Peter.

    GEO,

    Do not build your strings in an array of strings.  An array of strings are written a / line in the function "write text to a file.

    Use the function to concatenate strings and string together a tab character between the date/time and the first value.  The "write text to file function will add its own chain of end of LIFE at the end of writing.

  • Write to the file

    I am constantly writing data in 2 columns in a spreadsheet file in a loop of the consumer. I would like to topics (string format) at the top of the worksheet. I have attached an extract of my code showing what I'm doing now... I want these positions to be written to the file once and write the data in the same file under the relevant headings. However, currently my headers are written to the file with each iteration of the loop instead of writing just once.

    I tried a few different variations of my extract attached code, including by combining data and position in a table and using a write to the worksheet vi, but a similar output occurs

    I looked at the previous threads highlighting similar problems, but found nothing that helped me with my problem

    Move writing the header outside the loop or put it in a case statement that she writes only on the first iteration using the loop counter.
