How to search a file .csv for data using its timestamp, then import into labview

Hi, I am currently get density, viscosity and temperature of an instrument, adding a timestamp data and write to a .csv file that I can view in Excel. It works very well (see attached code) but reimport what I have to do now is search this csv file of data that has been obtained at one time, temperature, density & the values of viscosity at the moment in Labview to do some calculations with them, so that the data acquisition process is still ongoing.

I found several examples on how to import a CSV together in labview, but none on how to extract data at a specific time. Also, every time I try to do anything with the file .csv for my data acquistion VI is running, I get error messages (probably because I'm trying to write and import data from the .csv file at the same time). Is there a way to get around this, perhaps using the case structures?

If you need to know my skill level, I use LabVIEW for a few weeks and before that have basically no experience of writing code, if any help would be great. Thank you!

TDMS is a little more complex than that.  Here is a proof of concept quickly lifting together:

You should look at some of the examples of read/write TDMS to get a better handle on the tool.  While I should...

  • How to create a file .eas for sprite sheets?

    Hello

    Does anyone know how to create a file .eas for sprite sheets.

    It looks like a data xml file that would normally correspond with a sprite sheet. I usually use automated sprite sheet software to create the xml data form. I don't see the option for .eas export file in the software of the packer of texture that I use.

    It would be convenient that Photoshop has the ability to export an eas... perhaps with a plugin.

    Thanks for your help.

    EAS file format is also a JSON format, but is specific on board animate. Currently, this spritesheet format can be generated from Flash Pro CC 2014.

    Spritesheets (image file with sprite of equal size stacked in the order) of other tools like packer of texture can also be imported in animate as the dialog box animate import Spritesheet support it. Production however you specify the rows/columns and parameters in the import of fill dialog box so that the sprites are created with precision.

    Plese do try it and let us know if it works for you.

  • How to automate the process of loading data using load file & Task Scheduler

    Hello

    I do the automated processes to load the data into Hyperion Planning application using the file data_Load.bat & Scheduler of tasks.

    I created Data_Load.bat file, but the rest of the process, I cannot complete.

    Could help you me, how to automate the process of loading data using the file Data_load.bat & task Scheduler or what are the rest of the file is require it to achieve.

    Thank you

    In response to your question using the maxl for loading scripts?

    If Yes, I've seen and deliver in the batch (ex: load_data.bat) that is you do not have the path of the maxl script complete with a batch when passing through the event the task scheduler will work, but the log file and / or error will not be created. Which means lots claims it linked task scheduler, although he did not do what you need to.

    If you use maxl use this as the batch

    "essmsh C:\data\DataLoad.mxl" or you can also use the full path for the maxl or work elsewhere. The only reason why I think that the maxl can then not work is if you do not have the updated batch updated to call on all LANE changes maxl or if you need to update your environment variables to correct the command essmsh to work in a command prompt.

    Signature of application information has not yet been published.  You can submit your application unsigned.  In addition, in FB4, in the Properties window of the project, under the Flex compiler, you can add

    -debug = false

    to compile without debugging information.

    Otherwise, .bar file creation is done in a regular compilation with BB CLI package.

    How should be written the script for the use of the maximum memory of the guest operating system ever?

    Please teach the name of the object and the type and order, etc.

    You should be able to do it with the cmdlet Get-Stat .

    Something like that

    Get-Stat -Entity (Get-VM $vmName) -Stat mem.usage.maximum -Start (Get-Date).AddDays(-7) | Measure-Object -Property value -Maximum | Select Maximum
    

    This will return the maximum percentage in the last 7 days for the guests, whose name is stored in the variable $vmName.

  • How can I play files CSV lines with a different number of columns?

    Hi all

    I am trying to load CSV with DIAdem 2014 files, and I found there is a great tool, "use".

    However, with the CSV use tool, there are critical problem with my data files. (See photo)

    As you can see the CSV file attached, it includes a lot of lines with different columns.

    And here, use read the number of columns of 1st line (e.g.: 4 columns) and set it as the number of columns to read.

    So I can not load all of the data (e.g.: 53 columns) if first row data were lower than columns.

    Can anyone recommend any approach, please?

    Kind regards

  • How to search the file using the keyword under Windows 7?

    I search the file with ABC as a keyword in the file name in the D: drive and would like to know how to search on Windows 7.

    Does anyone have any suggestions?

    Thanks in advance for your suggestions :>

    Maybe all you want to do is to go in drive D itself (click here to open a window for her) and access the white search in the upper right of this window, where there is a small magnifying glass showing.  To limit the search file name, you can enter:

    name: abc

    If you want to search independently incorporated between the other letters abc, enter:

  • File system for data Essbase = &gt; NFS or other?

    Hello!

    We strive to put our Essbase cubes on a NFS file system shared for our Essbase cluster

    Performance is weaker than expected (2 x slower than our current configuration)

    I saw on internet that NFS is not recommended for Essbase 9 but nothing for Essbase 11.1.2.3.x on the doc of the EMP.

    -Are you using NFS for your Essbase data? What version of v3, v4?

    -What type of FS do you recommend (for linux)

    Thank you!

  • How to rename a file flat concatenation date and time, file name?

    I created a package where I run a first interface that uses a flat file to a server and load into a table of Teradata.

    After using the OdiFtpPut API, I used a FTP file and send to an outfit.

    Given that this procedure works every day, I need when FTP get concatenation destination file name, the date and time of execution.

    What is the best practice for this?

    using the odi APIs, you can get the date and time

    <%=odiRef.getSysDate("dd_MM_yyyy_hh_mm_ss")%>
    

    To rename, you can use the operating system command or using the command/UNIX windows and rename the file by adding the getsystdate API.

    Hope this fixes your condition
