Importing data from third party file with specific layout

Hello everyone,
I have been searching the forum and googling for help on this but so far no success.
The issue I have is the following:
- I need my client to provide data to me in 2 different dates (Date 1 and Date 2), for example, a bank account balance;
- He has already provided me with data for "Date 1" in the previous year and this information is stored in a file, generated by a government software;
- I have the file layout provided by the government, establishing the location and number of characters where the information is stored (e.g. need to import characters 4-12 of a specific line in the file);
- I need to be able to read from this file and pre-populate field "Date 1" with the amounts informed previously;
- I will then send a PDF form for him to update the "Date 2" field, using the amount in "Date 1" as a reference.
Is there any way I can do this?
I like researching and do this as a hobby, therefore I don't expect to receive pieces of code already prepared - I would just appreciate if anyone could point me in the right direction here, as my coding skills are from a guy interested in learning things.
Many thanks in advance for all the help.
P.S.: the government software can generate a .PDF file and the data I need is reported there, just in case it is easier to work with a PDF file instead.

Hi,
Looks like that you are using relative path. Then, the file must be located in MathScript search path. Otherwise, MathScript can not find that file. You can either specify the absolute path or add the path to MathScript search path list.
I have tried in LabVIEW 8.6. dlmread should work well to read data from .txt file.

  • Importing data from a text file with MathScript

    Hi,
    I currently have a bit of Matlab code that imports a load of data from a tab-delimited text file. The text file is in the same directory as the .m file and my .vi file. The relevant line of import code from Matlab is:
    data=dlmread('data.txt','\t',5,0);
    When I run this in Labview after importing the code into a Mathscript block and connecting two relevant outputs to a "Build XY Graph" block such that the variables can be plotted, I get a message saying:
    "Error -90001 occured at Error in function dlmread at line 10. Labview: File not found..." 
    How can I get LabVIEW to read the file? Sorry if this is a stupid question but I'm new to LabVIEW, having come from Matlab! 
    Thanks for the help

    I'm new to WFM.
    Question:
    Can WFM import or use historical data that is exported from the Avaya ACD?
    It would be nice to use the existing data for forecasting.

  • How to import data from a text file into a table

    Hello,
    I need help with importing data from a .csv file with comma delimiter into a table.
    I've been struggling to figure out how to use the "Import from Files" wizard in Oracle 10g web-base Enterprise Manager.
    I have not been able to find a simple instruction on how to use the Wizard.
    I have looked at the Oracle Database Utilities - Overview of Oracle Data Pump and the Help on the "Import: Files" page.
    Neither one gave me enough instruction to be able to do the import successfully.
    Using the "Import from file" wizard, I created a Directory Object using the Create Directory Object button. I Copied the file from which i needed to import the data into the Operating System Directory i had defined in the Create Directory Object page. I chose "Entire files" for the Import type.
    Step 1 of 4 is the "Import:Re-Mapping" page, I have no idea what i need to do on this page. All i know i am not tying to import data that was in one schema into a different schema and I am not importing data that was in one tablespace into a different tablespace and i am not R-Mapping datafiles either. I am importing data from a csv file.
    For step 2 of 4, "Import:Options" page, I selected the same directory object i had created.
    For step 3 of 4, I entered a job name and a description and selected Start Immediately option.
    What i noticed going through the wizard, the wizard never asked into which table do i want to import the data.
    I submitted the job and I got ORA-31619 invalid dump file error.
    I was sure that the wizard was going to fail when it never asked me into which table do i want to import the data.
    I tried to use the "imp" utility in command-line window.
    After I entered (imp), i was prompted for the username and the password and then the buffer size as soon as i entered the min buffer size I got the following error and the import was terminated:
    C:\>imp

    Please show me the easiest way to import a text file into a table. How complex could it be to do a simple import into a table using a text file?
    We are testing our application against both an Oracle database and a MSSQLServer 2000 database.
    I was able to import the data into a table in MSSQLServer database and I can say that anybody with no experience could easily do an export/import in MSSQLServer 2000.
    I appreciate if someone could show me how to the import from a file into a table!
    Thanks,

  • I need to import data from a CSV file to an Oracle table

    I need to import data from a CSV file to an Oracle table. I'd prefer to use either SQL Developer or SQL Plus code.
    As an example, my target database is HH910TS2, server is ADDb0001, my dB login is em/em, the Oracle table is AE1 and the CSV file is AECSV.
    Any ideas / help ?

    And just for clarity, it's good to get your head around some basic concepts...

It does not have any code of it's own (although it may have some "commands" that are SQL Developer specific)
    SQL*Plus is another front end (character based rather than GUI) that submits code to the database and displays the results. It also does not have code of it's own although there are SQL*Plus commands for use only in the SQL*Plus environment.
    The "code" that you are referring to is either SQL or PL/SQL, so you shouldn't limit yourself to thinking it has to be for SQL Developer or SQL*Plus. There are many front end tools that can all deal with the same SQL and/or PL/SQL code. Focus on the SQL and/or PL/SQL side of your coding and don't concern yourself with limitations of what tool you are using. We often see people on here who don't recognise these differences and then ask why their code isn't working when they've put SQL*Plus commands inside their PL/SQL code. ;)

    Hi,
    Here are the basic steps needed to read data from excel spreadsheet using the Java Excel API(jExcel API).
    jExcel API can read a spreadsheet from a file stored on the local file system or from some input stream, ideally the following should be the steps while reading:
    Create a workbook from a file on the local file system, as illustrated in the following code fragment:
              import java.io.File;
              import java.util.Date;
              import jxl.*;
             Workbook workbook = Workbook.getWorkbook(new File("test.xls"));
    On getting access to the worksheet, once can use the following code piece to access  individual sheets. These are zero indexed - the first sheet being 0, the  second sheet being 1, and so on. (You can also use the API to retrieve a sheet by name).
              Sheet sheet = workbook.getSheet(0);
    After getting the sheet, you can retrieve the cell's contents as a string by using the convenience method getContents(). In the example code below, A1 is a text cell, B2 is numerical value and C2 is a date. The contents of these cells may be accessed as follows
    Cell a1 = sheet.getCell(0,0);
    Cell b2 = sheet.getCell(1,1);
    Cell c2 = sheet.getCell(2,1);
    String a1 = a1.getContents();
    String b2 = b2.getContents();
    String c2 = c2.getContents();
    // perform operations on strings
    However in case we need to access the cell's contents as the exact data type ie. as a numerical value or as a date, then the retrieved Cell must be cast to the correct type and the appropriate methods called. The code piece given below illustrates how JExcelApi may be used to retrieve a genuine java double and java.util.Date object from an Excel spreadsheet. For completeness the label is also cast to it's correct type. The code snippet also illustrates how to verify that cell is of the expected type - this can be useful when performing validations on the spreadsheet for presence of correct datatypes in the spreadsheet.
      String a1 = null;
      Double b2 = 0;
      Date c2 = null;
                        Cell a1 = sheet.getCell(0,0);
                        Cell b2 = sheet.getCell(1,1);
                        Cell c2 = sheet.getCell(2,1);
                        if (a1.getType() == CellType.LABEL)
                           LabelCell lc = (LabelCell) a1;
                           stringa1 = lc.getString();
                         if (b2.getType() == CellType.NUMBER)
                           NumberCell nc = (NumberCell) b2;
                           numberb2 = nc.getValue();
                          if (c2.getType() == CellType.DATE)
                            DateCell dc = (DateCell) c2;
                            datec2 = dc.getDate();
                           // operate on dates and doubles
    It is recommended to, use the close()  method (as in the code piece below)   when you are done with processing all the cells.This frees up any allocated memory used when reading spreadsheets and is particularly important when reading large spreadsheets.              
              // Finished - close the workbook and free up memory
              workbook.close();
    The API class files are availble in the 'jxl.jar', which is available for download.
    Regards
    Raghu

  • Error in importing data from multiple ASCii files, Concatenat​e

    I am trying to use the "Importing Data From Multiple ASCII FIles.VBS" and the "Concatenate Groups.VBS" scripts downloaded from here, http://zone.ni.com/devzone/cda/epd/p/id/3870.

    Please have a look at the DIAdem Example to concanate channels. Its delivered with DIAdem.
    Examples > Creating Scripts > Scripts > Appending Channels to Each Other
    Please use a dataplugin (File -> Text DataPlugin Wizard...) or the csv plugin to load your data.
    Greetings
    Andreas
    P.S.: The one you have downloaded needs the old Ascii Wizard that is not activated by default in newer DIAdem versions.
    If you want to use it anyway:
    Settings -> Options -> Extensions -> GPI Extensions ...
    Add gfsasci.dll

  • Importing data from an .mht file

    I would like to import data from a *.mht file. I can open the file in excel and save it as excel but I want to automate this in SSIS. I found a command line tool but it's not doing it correctly but excel does.
    Can I do this in VB script in a VB task?
    OR is there an odbc provider for the .mht file so I don't need to convert it at all?
    Thanks,
    Linda

    it converts to an excel manually and then can import it just fine. it's a report and the source will only give us an .mht file for importing into our database.
    any ideas how to automate converting to excel in VB script or do I have to build an .exe and run it via command line or something?
    Thanks
    I seriously doubt anyone around here will know how to do this I'm afraid because its nothing to do with SSIS. What I do know is that you can use the Office PIAs to automate many Excel tasks from .Net code so if you can figure out how to do that then you put the code inside a SSIS script task. At that point we may be able to offer some assistance but not until then.
    In other words, if you want to programatically open the .mht file in Excel you'd be better advised to get the advice elsewhere I'm afraid.

  • How to create PDF from text file with specific layout?

    I wanted to create the pdf from text file in specific layout - Landscape orientation and JIS B3 Page size while at Adobe Acrobat Pro.
    In past, I could do a right click on a text file (desktop area) and select print to print out the document into .pdf BUT only if I set the Adobe PDF to Landscape and JIS B3 Page size BEFORE.  And I could only do 15 text documents at once.
    I wanted to see if I could do the create the pdf from text file with specific layout in Adobe Acrobat without having to go to Control Panel to preset the Adobe PDF to specific layout at every time.   I would have to set Adobe PDF back to normal layout after I'm done with these pdf print outs.  I do lots of pdfs in normal layout.  Sometimes I would forget to do that.
    So, How do I do that?

    No such luck.  It would output the contents in letter size even in JIS B3 Page layout at MS word. 
    Is there a script or action where I could set the orientation and page size before creating PDF on these text files?

  • How to import data from corel draw file

    Dear Fellows

    (BASIT)

    This can be automated... Most Windows applications support (or did support) DDE (Dynamic Data Exchange). In its basic form, you can send DDE commands to an application. E.g. load file using this filename, use the selection option on the menu, save the selection as a text file, etc.
    In other words, you can interact with an application using DDE only - no keyboard or mouse input required.
    DDE itself is fairly straightforward and not that difficult to code - the complexity is in the DDE payloads that need to be send to the application to make it behave the way you want it to. In the "old" days, this was documented in some fashion by applications. I cannot recall seeing any specific DDE commands and specs for common Window applications for many years now. Also, DDE was made part of the then new OLE2 spec and have since taken a backseat.
    Not even sure if apps today still properly support it...
    So instead of putting Corel data into Oracle, I would rather look at it the other way. After all, Oracle is the server - not Corel. Have a web front-end (written in APEX) that allows you to specify the participant's details and store this in Oracle.
    Create an export filter in Oracle that dumps this into a XML (or similar) format understood by Corel. Having Corel open this file, convert it, and print it. Then look at how to automated these steps in Corel (using VB for Apps or something).

    Hello Peter, and thank you for your reply's.
    My problem is that I'm receiving the data from the external
    file and I don't know how to get the children in place... I mean, I
    also have some data being received form a file that I can convert
    into an array collection, but the thing is, that file doesn't have
    children structure...
    It's something like this:
    <?xml version="1.0" encoding="utf-8"?>
    <items>
    <item id="T1" resourceId="R1" name="Cardiologia"
    startTime="25-3-09 8:0:0" endTime="25-3-09 8:30:0" />

    startTime="26-3-09 8:0:0" endTime="26-3-09 9:0:0" />
    </items>
    And I solve it with this (don't know if is the best):
    private function onResultHttpServiceTask(e:ResultEvent):void
    var a:Array = xmlListToObjectArray(e.result.item);
    tasks = new ArrayCollection(a);
    protected function
    xmlListToObjectArray(xmlList:XMLList):Array

    for each(var xml:XML in xmlList)
    var attributes:XMLList = xml.attributes();
    var o:Object = new Object();
    for each (var attribute:XML in attributes)
    var nodeName:String = attribute.name().toString();
    var value:*;
    value = attribute.toString();
    o[nodeName] = value;
    a.push(new ObjectProxy(o));
    return a;
    But when the children "enter in action" I don't know how to
    bring them to the array...
    This code you send it's preaty much the thing I need, but the

  • How to parse data from a text file with no convenient delimiters?

    I need to read data from a text file.  This file contains one line of data with the repeating pattern "time 00 ADVar2: ___ Height: ____ time 01 ADVar2: ___ Height: ___ ..."  I need LabView to parse out the "time" and "height" values, build an array with the values, and graph the correlation on an X&Y plot.  Does Labview have an automated way to read to the input data file and parse out the correct values, even without convenient delimiters?  Thank you.

    You actually do have a convenient delimiter: "time". Thus, you can make an array using that as the delimiter. Only caveat is that the first array element will be empty. Then you can conveniently use the Scan From String function in a for-loop. Something like this:

  • How to do import data from the text file into the mathscript window?

    Could anyone tell me how to do import data from text file into mathscript window for labview 8?
    MathScript Window openned, File, Load Data - it has options: custom pattern (*.mlv) or all files. 
    Thanks

    Hi Milan,
    Prior to loading data in Mathscript Window , you have to save the data from the Mathscript window (the default extension of the file is .mlv but you can choose any extension). This means that you cannot load data from a text file  that was not created using the Mathscript window.
    Please let me know if you have any further questions regarding this issue.

    Now I want to import the data from these csv files into the tables on second machine. if I've 50 such csv files, then data should be written to 50 tables.
    I am new to this. Could anyone please let me know how can I import data back into tables. i can't use sqlloader as I've to satisfy a few conditions while loading the data into tables. I am stuck and not able to proceed.
    Please let me know how can I do this.
