• read data from xlsx file

  How to read data from an Excel 2010 worksheet with the .xlsx extension?  The data I want, it's on one of the 10 tabs in the file, I have to choose which programmatically.  I have the Report Generation Toolkit for LV2012, but all the screws that come with it seem to focus around writing data to a spreadsheet Excel and make charts and whatnot.  I want to * read * an Excel worksheet.  Seeking answers led to many 'Open it and save it as tab delimited text', which I can't do because I need data from different tabs, and because this file is quite dynamic with many users opening and adding several times.  In order to save the tab I want as a tab delimited text file per programming, I'm back a square, how to open it?

  My solution would ideally fill in the blanks of: spreadsheet.xlsx---> _---> 2 or 3D data table.

  Thank you

• Reading data from a text (JS CS3) file tabs-delimited

  Hi - I'm working on a script to read data from a text file and use in a dialog box. But I hit a wall.

  I used a script from a previous post that defines a variable text document when the user script he chooses from a drop-down list.

  var myDialog = app.dialogs.add({name:"Map",canCancel:true});)
  {with (MyDialog)}

  {with (dialogColumns.Add ())}
  {with (borderPanels.Add ())}
  staticTexts.add ({staticLabel: "choose the location :"});})
  {with (dialogColumns.Add ())}
  
  var file = File("~/Desktop/myPlacesfile.txt");

  leader. Open ("r");
  var str = file.read ();
  leader. Close();
  var myPlaceList = str.split (/ [\r\n] + /);
  var myPlaceMenu = dropdowns.add ({stringList:myPlaceList, selectedIndex:0});})
  }
  }}}
  Ditto var = myDialog.show ();
  if(myResult == true) {}
  If (myPlaceMenu.selectedIndex == 0) {}
  myPlace var = ' - undefined ";
  } else {}
  myPlace var = myPlaceList [myPlaceMenu.selectedIndex];
  Alert (myPlace);
  }

  myDialog.destroy ();
  }

  That's what I do now:

  The text file is in this format:

  Value1 value2 [TAB]

  Value1 value2 [TAB]

  Value1 value2 [TAB]

  I need to have the drop down dialog box show only the value 1, and after that the user selects, the script returns only the value 2. (The alert is just there to test - I'm doing something else with the variable).

  Is there a way to view the first part of a tab-delimited line in the menu drop down and return the second half as a variable?

  Any help would be greatly appreciated.

  Thank you

  One of the possibilities is that it. Create a table to the left of the values of the tab of the dialog box. Then create an object that you use it as a table of correspondence. Roughly as follows:

  same thing as what you have

  leader. Open ("r");
  var str = file.read ();
  leader. Close();
  var array = str.split (/ [\r\n] + /);

  'pairs' are the table of correspondence

  pair of var = {};

  as before, 'myPlaceList' will be used for the menu drop-down
  var myPlaceList = [];

  var v;
  for (var i = 0; i)< array.length;="">
  {
  v = table [i] .split ('\t');
  pairs [v [0]] = v [1];
  myPlaceList.push (v [0]);
  }

  Add the drop-down list as before:

  var myPlaceMenu = dropdowns.add ({stringList:myPlaceList, selectedIndex:0});})

  the table of 'pairs' correspondence is used as follows: pairs ['value1'] returns 'value2 '.

  so in your script that would be:

  myPlace var pairs = [myPlaceList [myPlaceMenu.selectedIndex]];

• Can read data from xls using teststand 3.5?

  Hello

  I use 3.5 TestStand and LabVIEW 8.je know these are quite old versions now, but we must continue with this on a test bench.

  My question is how can I read data from the file xls using TestStand 3.5? I have already mentioned a few posts on this, and one response suggested that I should use "tGetExcel" using ActiveX adapter. I tried to run the test example related to "http://forums.ni.com/t5/NI-TestStand/Write-or-read-to-Excel-from-TestStand/td-p/250439/highlight/tru...", but a run-time error. He says that "the tGetExcel type library information not found. Make sure that the server is registered in the system.

  TestStand 4.2, I could easily run excel at the base of operations by using the Office Excel Toolkit.

  I was wondering, is there another way, I can read just .xls file data by using Teststand 3.5?

  Thank you

  Niraj.

  Please check this example for charger of property:

  C:\Program Files (x 86) \National Instruments\TestStand 3.5\Examples\LoadingLimits

  This shows the limits of excel file loading.

  But you can load the values of the variables-consult the help file / Reference manual for this type of step.

  Also in the loader type forum search property - you can find more information.

  I hope this helps.

• Read data from table of $ E and insert in the staging table

  Hi all
  
  I'm new on ODI. I need your help to understand how to read data from a table ' E$ "and insert in an intermediate table.
  
  Scenario:
  
  The name of two columns, in a flat file, the employee and the employee id must be loaded into a data EMPstore +. A check constraint is added so that the data with the employee names in capital letters only to load in the data store. Check the command is set to the static movement . Right-click on the data store, select control , then check. The lines that have violated the check constraint are kept in E$ _EMP+ table.
  
  Problem:
  
  Problem is I want to read the data in the table E$ _EMP+ and transform in capital letters in the name of the employee and move the corrected data of E$ _EMP+ EMP+. Please advise me on how to automatically manage the 'soft' exceptions in ODI.
  
  Thank you

  If I understand, you want to change the columns in the tables of $ E and then load into the target.

  Now, if you notice how ODI recycles the error, there is an incremental update to the target using the E table $ after he filled the I$ table.

  I think you can do the same thing by creating an interface using the table of $ E as source and implement the business logic in this interface to fill the target.

• read data from emparray

  I have a function that I would read in pl/sql. How can I read data from it. EMPARRAY function return.
  
  FUNCTION META_PODATKI_TABEL

  EMPARRAY is:

    2  /
  
  Type created.

• Read data from APEX_ITEM

  Hi all
  
  I searched the forums, and unfortunately I have no idea on how to go on the following.
  
  I have the following SQL report created with APEX_ITEM. SELECT_LIST-
  
  > select id, questions, APEX_ITEM. SELECT_LIST (p_idx = > 1, p_value = > '- Select Rating-', p_list_values = > 1, 1, 3, 3, 5, 5', p_attributes is > "style =" "color: Black;"', p_show_null = > 'YES', p_null_value = > NULL, p_null_text = > '- Select Rating-', p_item_id = > ' the ROWNUM # f01_ #', p_item_label = > ' label for ROWNUM f01_ # #', p_show_extra = > 'NO') 'Rating' of the sqa_customer_questions by id order
  
  Query runs as you like, but I don't know how to accept the values of the rows. I would like to insert the values of the selection list and their respective ID for all the entries in another table. I'm not able to find out how I could read data from these APEX_ITEMs and reach my goal.
  
  Any help is appreciated.
  
  Kind regards
  Jean-Pierre

  Nope,

  Can you put the app on apex.oracle.com

  In any case if you have a report like this

  SELECT id,
                  something
  FROM table
  

  You can do it for the

   SELECT id||APEX_ITEM.HIDDEN(2,id) id,
                  something
  FROM table
  

  And then reference it as APEX_APPLICATION. G_F02 (the first parameter provided to apex_item determine the number) in your process.

  See you soon

• Read data from the file into ArrayList

  Hello
  I have a class called product describing the charactristics of products such as the name, id, price etc.. I have the whole set and use the get methods in my class of product. I store the information on my products in an ArrayList. I can write the information on my products in a file.
  so far, but so good...
  
  I want now to re-read the data from the file and store it in my list of tables again. I know I can use Parsing and read in data in an ArrayList as String, int, double etc. but is anyway to read in from 'Product' (then it would be up to my class of product)?
  
  Thank you in advance.

  1. are you aware of serialization?
  2. get a name, I love not dealing with numbers.

• read data from xml file

  Hi all

  I have an xml file store on my bb.

  How can I read data within the tag? I think that one way is to use blackberry.find.FilterExpression (), like the example below. I don't know how... but it's okay. I will try!!

  function handleOpenedFile(fullPath, blobData) {
  
      temp = blackberry.utils.blobToString(blobData);
  
     //var NomeOperatore = blackberry.find.FilterExpression('');
  }
  
  function readPianoViaggi() {
      if (blackberry.io.file.exists(filePath)) {
          blackberry.io.file.copy(filePath, filePath2);
          blackberry.io.file.readFile(filePath, handleOpenedFile);
  
      }
  }
  

  my question is: I can read data within the tag using an operation such as

  itemDescription = temp.getElementsByTagName ('NomeOperatore') var [0].firstChild.data or something similar?

  Thank you

  You would do something like the following... I don't know if my syntax is correct

  function readFile() {
    blackberry.io.file.readFile("file:///store/home/user/sample.xml",handleOpenedFile);
  }
  
  function handleOpenedFile(fullPath, blobData)
  {
    var xmlString = blackberry.utils.blobToString(blobData, null);
    var parser = new DOMParser();
    var doc = parser.parseFromString(xmlString, "text/xml");
  
    var itemDescription = doc.getElementsByTagName('NomeOperatore')[0].firstChild.data;
  }
