Help! Trying to write an array to a file without having to rewrite the old data each time.

Hey everybody,

I have a vi that takes a 2D array and writes to an xml file. The purpose for this is to characterize the pathloss through a matrix dowkey 10 x 10 to different frequencies. I use this program to create a table of correspondence for the switching matrix, so when I make one of my tests I can get an accurate measurment. The problem with this is that I take data points about 299 by combination of matrix switches leading me to data more than 32000 points in the lookup table. I use xml because each data point requires a header so I can analyze via the table of correspondence with another of my vi when I need that pathloss. What I'm trying to fix, is that when my vi wrote in a file at a time to save memory space, he wrote a single Bay. When writing, it rewrites the old data, and then the new data. As the number of points of data increase so does the time of latency of writing in the file. At the time wherever I am finished, it takes about five hours to completely write to the file. Does anyone know how to write about writing to a file without having to rewrite all the old data? Attached, it's my vi to write to the file, my vi for research in the file and an example of one of my tables in research.

Thank you

Dustin

  • I am trying to rebuild my old iTunes library (hoping to keep notes, play counts, playlists, etc.) on a new laptop of an old PC, even if the only files I have to use the old are the .xml, .itl.

    I am trying to rebuild my old iTunes library (hoping to keep notes, play counts, playlists, etc.) on a new laptop of an old PC, although the only files I have to use the old are the .xml, .itl and current music files. Is this enough information to do it, and if so, how should I do?

    I lost the other information by following the instructions found online of other attempts. I have unfortunately seem to have lost all that concerns my old library with the exception of the foregoing. I have been using an external hard drive to make this attempt. When iTunes opens it is empty, and when you try to import the .xml I only get playlists, although there is nothing inside of them. It would not be the end of the world for me to start all over again, I've not lost music files, but loading in my all of my old info is much, much, much more desirable. Thank you!

    I'm sure that the sides are stored with the file of 80%. (wav mp3/4 whatever)---> or at least the should be!

    Just install itunes.

    Copy the contents of your old folder in the itunes directory and start itunes--> it will do the rest.

    PS...
    However, I wouldn't bother with itunes more... windows media player is pretty cool in 7, does all the same things.

    Personally I stick with the purchase of CD (mp3 downloads are a rip off)

    "I'm ashamed to say.

    No need to be ashamed, why reinvent the wheel?

    A way I use to transmit back data is as follows:

    getAddressContacts extractScreen = new getAddressContacts();

    UiApplication.getUiApplication () .pushModalScreen (extractScreen (;)

    Contact extractedContact = extractScreen.getExtractedContact ();

    To use it, you add a getExtractedContact method to the screen of your getAddressContacts and make sure that it can return the contact of the extract.

    Make sense?

  • HELP ME PLEASE! Dynamic PDF with the table increases each time he has saved and reopened? HELP PLEASE!

    Hi, I hope someone can help me. I created a form (dynamic pdf) with Livecycle ES 8.2.

    This document contains a table whose rows are added when the user clicks a button.

    The document in the design stage contains no more than 1/2 an A4. Here are my two problems;

    1. when the document is opened in Reader (9.3), it is formatted correctly to accept the line after line, it's default state (which can be added to by clicking on the button) is now three rows?

    2. the question whether the two additional lines are deleted or populated or if several lines are added and populated, if the document is saved and opened again with the player, he became a full page (default empty lines). If saved, it grows up to 4 pages and so on.

    Can someone help me please. I can provide a copy of my file if necessary.

    I don't know if that makes a difference, but the document is protected with a password to open in Livecycle and it also has user rights assigned to the user to be able to save a copy on their local machine (not only allowed to fill and print).

    My email is [email protected]

    Would appreciate any help that can be offered. My document is ready (accept for that matter) for me to use in my work.

    Concerning

    Bradd

    Bradd,

    Please send the form and I can take a look. If you wish to send a version of the form that is not password protected or send the password in a separate email, it is up to you.

  • Can LabVIEW VIs database connectivity write an array to a single cell?

    Hello world

    I wonder if DB tools insert data VI is able to accept a table as its input. It's a bit difficult to say because all connect you to the input of this VI is voluntarily accepted by the terminal, data type variant so no glaring broken threads occur when associate you a table.

    What I'm trying to do, it is write a table 2D of doubles in a single cell in a table. The table is large 3 x 1000 elements. I confess to being completely new to databases and such an effort may or may not look ridiculous in the database world. If someone wants to talk about why I'm trying that I'll gladly go through my reasoning - just enough to say that I'm not totally crazy.

    When I try to write the table to a single cell, an error as seen in the attached screenshot. All my other functions database, working with scalar values of many different types of data, all work very well.

    I have attached the problematic code. It tries to write these tables 8 to 8 individual columns, all in the same line. I'm just using the method "automatic" for now.

    Extra tid bit of information:
    OpenSQL database. Connection via ODBC 5.2 64 bit, user DSN.

    LabVIEW 2012 not SP1. Windows 7 64-bit.

    Thank you all!
    Rhys.

    Convert the table to a spreadsheet string and store it like that.

  • Where support (with read/write access) files should be placed on the computer target?

    I am building a LabVIEW application that will be distributed to more than one PC. I have I need to read and write in a configuration file. I need a file location that I can reach on the vast majority of computers that run Windows XP and VISTA. VISTA seems to restrict the ability of an application to create and write files to the folder program files. Where is the best place to store this file? Any suggestions will be greatly appreciated. Thanks, Dave F

    Microsoft recommends that the exact locations of a registry keys to store information for different purposes.

    These are the rules that we use in the company and they also works in VISTA and Windows 7.

    Do not click on links. Small is an excerpt from our online help and I din't had a method to convert them to plain text without having to rewrite them.

    LabVIEW and the Windows registry store information where these files are located in the file system.

    I got my XPS in 2014 and my warranty of service completed in 2015 Jan before I installed Windows 10. So since I've upgraded to Windows 10 I started having problems with by XPS 8700. Now, I have no guarantee. I thought he would go better once they have released an update of the BIOS and it did for a while unfortunately in recent months, I noticed two major issues.

    (1) upon the starting and restarting my computer, my monitor does not end up receiving the signal from the computer and remains dark.

    -Checking that it is not a problem with the monitor by testing with other computers

    -J' checked in the Device Manager and there was a next yellow alert for graphic cards / NVIDIA GeForce GT 635

    -By clicking on, he showed me this: Windows has stopped this device because it has reported problems. (Code 43)

    Unfortunately, it is not the only problem with the graphics card.

    (2) "sleep" my mode is gone (it is related to graphics and BIOS).

    -J' tried the go in power to add setting but it was not yet listed.

    -I went to the command prompt and looked powercfg.exe that's what I discovered:

    C:\Windows\System32>Powercfg - a

    Now I really wish I could start or restart my pc without staring at a blank screen and the problem of code 43 with Nvidia GeForce GT 635. Also, I would if I could have the option to upgrade my PC to sleep. I really miss it and do not have to constantly reboot my computer to be able to see anything on the monitor.

    I hope someone can help me with these questions without having to reset the pc and reinstall, all over again, that the problem still exists in other cases (I don't have a copy of the installation of programs pre-installed dells so...). This computer is only 2 years old, it didn't need to be retired.

    NVIDIA GeForce GT 635 (PCI\VEN_10DE & DEV_1280) the card is physically wrong and needs to be replaced.
