• Is there a maximum size or the limit of text file during storage and data transfer?

  HI -.

  We used WriteExtFile and AppendExtFile to store data in a CSV text file in a data folder in the same location as the executable files of Authorware.

  WriteExtFile ("data\\"^"Variable_Names.txt", Survey_Variable_Names)

  AppendExtFile ("data\\Survey_DATA.txt", Survey_Data)

  As a general rule, we always put our executable files on the hard disk of the computer (c) due to some issues we had with an incompatible network drive in the past.  Have the files on the C: drive, eliminated any network problem.  Our data has accumulated would be always stored on the C: drive as well.

  Now, we need to store a backup copy of the data on a server, on the C: drive.

  My question is: is there is a maximum file size that can be "read in" and then "written" using Authorware?

  My thought was to use ReadExtFile to read the content of the 'Survey_DATA.txt' file and use WriteExtFile to write these same data on a drive on the network, by adding the date and time at the end of the name of the file as a backup file.

  I used this logic, which is working to write on the "P": network drive

  WriteExtFile ("P:\\Survey_Project\\BackupData\\DATA_BACKUP_"^Backup_Date^"_"^Backup_Time^".txt", Survey_Backup_Data)

  Of course, the size of the original text on the C: drive file will continue to grow because "AppendExtFile" is used to add the data of every investigation file in the data file (CSV, each record on its own line).  If the size of the file we will read again (ReadExtFile) will also continue to grow.

  Is there a limit to what we can read in and then write back?

  Thank you!

  My apologies, it has been a few years...

  CopyFile is a function that you can load the WinAPI.u32

  Once loaded, use it like this

  Success: = CopyFile (FileLocation ^ "Sourcefile.txt",)

  Destination ^ "DestinationFilename.txt") "

  Remember that you must include WinAPI.u32 with your packed files.

• Update the workspace schema and schema Post installation Analysis App

  Initially, I create the workspace schema and the schema analysis corresponding to an application in the diagram A title.  I am now interested to change the schema associated with the workspace and the application in the diagram B.  I can easily do that via the workspace management UI, but I need a way to this script, so I can deliver to customers.  Does anyone have a solution?

  Changes in the workspace can be performed using apex_instance_admin API methods ( add_workspace/add_schema/remove_schema etc.), even if this requires scripts must be run by a user with elevated privileges.

  Once the required schema is associated with the workspace, the analysis schema can be changed using the apex_application_install.set_schema method in a script to import.

• read and medium n data from text file

  I acquire [a waveform of reading] oscilloscope digital data that is stored in a column in a text file.

  I need to read selectable amount of data at average/parcel them points.

  So basically I want to have a text file with millions of data points, but I want to draw not to say that all 1000. data point. I tried a lot of things I found here on the forum, but as I'm new to LabView, none of them really worked.

  Does anyone have a suggestion.

• write the table in its entirety in text file after completing the data collection

  Dell NetBook, Windows XP home, OR-6008, Labview 8.5.1

  I read a psydo real-time app 8 analog signals at 100 Hz.  I can't write directly to a file of data during data collection (processor flash drive to slow down), but can store 4 2D tables separated, with one added timestamp data.  Once I finished collecting data, I would record each table in a separate text (csv) file.  Using takes a loop for in long and using the 'picture to a worksheet string' add labels that I can't change.  I'm climbing down a text file of 3 columns and lines equal the number of samples, I've collected (e.g., a 1 minute session would be 6000 rows and 3 columns).

• Possible to have a directory structure in the app/native file system?

  I have implemented some assets in the bar - descriptor.xml, some of which are files (to root) and some files (which have files and other subfolders in their midst).

  If I inspect 'BAR packages' with the IDE everything seems to look OK, IE:

  AppName.bar
  + native
     - File 1   - File 2   + Folder      - File 3      - File 4
  

  From code, I can call the function fopen() to files in the root (file 1 and 2 file in the example above) and read without problem.  However, any attempt to verify the existence of the folder with stat() or attempt to browse with opendir () /readdir () it fails completely, as if it does not exist.

  In fact, I tried iterate the contents of the folder root app/native with opendir () /readdir () in order to see what is there and it does not work too (opendir() returns NULL).

  I'm starting to think that simply directory on app/native operations are not possible.  Am I missing something?

  Thanks for your help everyone, after some messing around I managed to solve my problem (s)!

  I changed my code to use a relative path (app/native) rather than building an absolute path based on the working directory.  This solves nothing but contributed to make paths easier to deal with in general (note: sample PlayWavFileMakefile should probably be changed to use the relative method, since it's where I copied it from).

  Then, I changed the to a zip file .bar file to inspect the content and used perspective of information for the system of the IDE to inspect the mounted volume my application during execution.  Being new to this platform, I didn't realize you could do either of these things - everything checked OK, but this gave me full confidence that the problem was probably in my code and do with the operating system or my package bar.

  Finally I found that I had two problems:

  -The first was to make a stupid mistake when you use the QNX dirent_extra_stat specific structure to establish if a line item is a file or a directory during the iteration of the directory tree.

  -The second problem was hard to find but easy to solve.  I found that I could iterate directories using opendir () /readdir () successfully, but only on the main thread.  Most of my file access is on a thread of work however, and this does not.  By inspecting errno of the filesystem in the event of failure, I found that there was a story out of memory.  I realized that I had to use a larger stack size when creating the thread, and then everything worked OK.  Interestingly, I used only a small battery of 4K, which worked well on WIndows, OS X, iOS and Android, but I had to wear to 32K for the PlayBook.  Most likely, QNX uses the stack for many of its variables from work here and other platforms support the pile.

  I hope this can help someone else in the future.

• Is it possible to update the file descriptor of the assettype of basic assets?

  Hello world

  Is to update the file descriptor of the assettype core assets without dropping and recreating again anyway?

  I created a base with a descriptor file asset, but it has a text field with 50 on this character restriction. Now, I want to update the same file for maxlength 255 characters. Is there anyway to do this without deletion and recreation of the assettype basis?

  Thanks in advance.

  Kind regards

  Thank you very much, Sikora, worked perfectly

  Have another question? Can use us the same method to drop the columns also? As the update the ADF with fewer columns and then modify the table in the DB?

• update the text with xml, DDL data fields a selection of an identification number

  Hi guys,.

  It should be simple, but I can't seem to find a straight answer.  In short:

  The XML file contains the ID, name, location (so 3 extreme records in the example xml file)

  Form contains a dynamic drop-down list to allow the selection of ID and text fields to display the names of the partners and the location of this ID.  The setting of the drop-down list works fine, however I need to update the associated name and location if different from the other ID's fields are selected.  I guess I'll need some sort of event on the menu drop down update other fields with the name and location of the selected ID, but I don't know enough to have a stab at him.

  Please, please, please help, Im starting to pull my hair.

  James.

  Sorry, looking at him again I could have given a better description of what is happening.

  Have a look at this sample https://acrobat.com/#d=NO5o6NhPTQgSYu3SVoN7rQ and data to go with her https://acrobat.com/#d=jN * pRT4uGg05VU * sGWvjcA

  The thing I should have said and I guess that's your problem is the the Data property, I used in $data. Data.resolveNode (...) must match the item parent of the element of your event if xml looks like

  1

  name 1

  Location1

  It should be $data.events.resolveNode (...)

  Maybe I should have used "itemGroup var = $data.resolveNode ("events.event.» (()_eventId.value_===_«_«_+_xfa.event.change+_»_») "); "in this case, but I try and do the resolveNode go as low as possible.

• How to save data in the text file of Spartan 3

  Hi all

  I would like to kindly save the data table text file or a spreadsheet on vi using fpga spartan 3e as an fpga target. Once I added all the functions related to the operation of file, it gave an error that these functions are not supported by the target device.

  could you please help me with this

  Thank you

  Rania

  Hi David,

  Thank you for posting. You use LabVIEW? If so, what version of LabVIEW FPGA do you use? You use a host VI, or any deployment of code at your target to run? The file IO VI probably won't compile to target because they are not intended to be used on your host computer. Resources and the paths of files do not exist on the target FPGA, but rather on the side of the host. I have included a link below that describes how to transfer data between the FPGA and host. I hope this helps!

• Writing data in the text file or excel spreadsheet

  Hello

  I have a silly question to ask questions about the writing of data in a text file or a spreadsheet. I have an example that simulates a sine-swept DAQmx. The output it provides is the (amplitude and phase) frequency response function that is plotted on a graph (see VI) attached. I like to use these data for further analysis by transmitting the data to a text file or a spreadsheet. I've tried a few things, but the thread is broken. I guess I use the sink badly - so I was wondering, can you please advise me on what sink should I use?

  Your help would be very appreciated,

  Thank you very much

  REDA

  The wire is broken, because you cannot connect this type of data to one of these two functions. The data source type is a table 1 d of the clusters, where each cluster contains two tables. The text file write accepts strings, not clusters. Writing on a file action accepts dynamic data, and while you can convert dynamic data tables, there is no built-in mechanism to convert a table 1 d of the clusters of two matrices.

  What you need to do is to convert the data in a format which can be accepted by these functions. Since you want to have a "spreadsheet" file then you should use writing to the spreadsheet file that creates a delimited text file. Since the frequency data would be the same for the plot of the magnitude and phase diagrams, you can have 3 columns: frequency, amplitude, and phase. You can take off the items using Unbundle by name, and then create a table 2D of each element of the cluster. The real question is to know if you want to save the data at each iteration and if you simply add on the file. The attached figure shows write an initial header and then adding just streaming the data.

• How to write graph of waveform data to text file with the option to the user to do

  So, I'm new to labview and will have bad to write a program in particular.  I have a waveform graph that runs for 120 seconds, generating a sine curve.  I am, however, having a time difficult get the program to write the x and are coordinated in a text file.  I've attached what I have so far.

  The first task I was assigned was to write a program that creates a curve of snusoidal on the front panel by adding a data point every half second for 120 seconds.  The plot should starts only if the user presses a button to start.

  The next part is to give the user an option to write the data generated in a file of worksheet called 'sine.txt '.  The file name and location should be hard-coded.  The file must contain the x and there contact information of each data point in columns separated by tabs, also known as the delimited.

  I spent several hours refining the attached program, and I can't seem to make it work right.  Any suggestions would be helpful at this stage.

  Sincerely,

  A student of chemistry frustrated whose research mentor is out of town

  First, you create files Excel.  You create text files.  And it seems that your writing on a file already created X (time) vs Y (curve of data) that is delimited by tabs.

  All you do is simply too complicated or a Rube Goldberg.

  All you need is the joint.

• problem with the backup data in text file

  Hello

  The problem I am facing wihile, saving the data in the text file is that everytime when I'm slecting the path of the façade, data that are recorded are added with the previous data, not only in the new text, the new data set is saved but also, is there any previuos run for the program , the corresponding data is also present in this text file.

  However, when I change the same ''(file path) to 'constant' in the control block diagram, and then add the path of the file, it doesn't have this problem. Basically, changing the "file path" constant in the diagram of control block (so that it is displayed in the front panel) is at the origin of the problem.

  Help, please!

  Thank you

  Your shift on the loop Register For is not initialized. It will keep the value of the string since the last time that he performed. That initialize and it should solve your problem.

• How to view the data in the text file to the format column

  Hello

  I am acquiring data from an oscilloscope.

  Wen I save the data in a text file to aid wite spreadsheet string, all the displayed voltage values r first, then values of time... in addition to its delimited by tabs

  How can I view it like the r of time values in a single column and the voltyage of the r-values in the other column

  thanx

  Hello

  I don't know what is exactly the format that you found. I think you should try to use the function Array transpose (from the palette of function table) before you pass the array to write to string of spread sheet function or directly loyal to Terminal son transposes on writing worksheet function and see if you get the desired results.

  PS. : Share your code would be appreciated.
