• How to read formatting excel worksheet as an array of strings

  I use the report tool to read an excel spreadsheet in an array of strings of LV.  It works fine except that it reads the precision of digital cells (~ 10 digits of precision).

  In my workbook I have displayed accuracy the value 2.  Is it possible to read the table such that it is displayed instead of the way it is stored internally?  (BTW, I understand how to do this)

  manually by parsing the string array and limit myself to the accuracy but would prefer to use excel itself to determine accuracy)

  sachsm,

  This should allow you to get the text from a cell or a range of cells.  Sort of do a "paste special" 'values '.

• Setting the size of the font of an array of strings programmatically

  I can't find the correct property to programmatically adjust the size of the font of an array of strings.  For a chain, it is quite easy with a property node and the text. FontSize property.  There must be a similar property to an array of strings, but I'm not.  Can anyone help?

  Take the element ref table and class type a more specific (string) and then you can set with a property node's font size.

• reading of the worksheet does not all columns

  Dear users and moderator.

  I'm trying out a text delimited by tabs of the data file. I would like to transfer the data in a table 2D with VI 'Read the worksheet file', but it seems that only the first column is acquired.

  I checked and the delimiter is fine. I also tried to change the format, but without effect.

  Does anyone have an idea about the problem?

  Thank you very much and good luck.

  Andrea

  You must put the tab delimiter character correctly. Right-click on the delimiter string constant code and select display.  It will show \\t.  Remove one of the backslashes. Otherwise, simply replace it with the character of tab delimiter string.

  

• How to divide a string into an array of strings in separate tables

  Greetings,

  I have an array of strings which displays strings in a text file. I read each line of the text file and put it in an element of the matrix of the chain.

  Now, I'm trying to divide each string for each part of the chain, then put in a separate table. Each element in the chain is separated by a comma. I hit a brick wall at this point and would like to help please?

  The purpose of this is so that I have 4 tables that will be ready their item values and set variables based on these values until I went through all the elements in each array.

  Attached example.

  Also my VI is attached.

  Thanks in advance for your help.

  Then just use Index Array on 2D array provided.

  

• Write the spreadsheet in an array of strings on a different worksheet

  Hello

  is it possible to write the spreadsheet to a table of chains, but to an additional worksheet?

  I am writing the results of the spreadsheet, but I want to create a different worksheet so that I can put the raw data.

  is this possible?

  If so, how?

  

  You can't unless you start using ActiveX or report generation tool to connect with a real spreadsheet .xls file.

  You are read and write a text file in the form in the way of a spreadsheet with delimiters between values in a row and the lines of text on the other.  Text files have no understanding of the data being on a "sheet" and other data on another.  It is a peculiarity of the format property of Excel file (and thus other spreadsheets) that allows Excel what data need to be put on what spreadsheet.  It is not the kind of information that you can pass along the use of LabVIEW based text file i/o functions.

• Reading of the worksheet causes error 7

  I'm reading from a .dat file that is constantly (not controllable) updated by another program.

  Each time the error window appears, showing the error 7.

  I guess that's when the other program is updated the file. My problem is that whenever the error message the program stops until I hit continue. Reading worksheet function is not an error output so I can't wire a clearerror.vi to it. I have already disabled the automatic management of errors for the vi and the block diagram, but the error still appears.

  How can I ignore a mistake like that?

  Change the lines of reading file Subvi one remove the General error handler, or change the type of dialog box for "No. Dialog. You'll want to give a new name and save to a new location. Even with the higher level. Add a connection error would also be a good idea.

• reading of the worksheet try to open two files

  I want to open multiple files and combine them. I tried to make a loop with a variable number of iterations depending on how many files, I intend on the combination. In the loop for example, I placed a reading of spreadsheet. When I run the vi with highest point running on, it works perfectly - exactly how I intended. When I run without, his version of spreadsheet always try to open a file more than the number I said and then crashes. I can't understand what is happening because it works fine when I am debugging.

  Thanks for your help!

  Sorry if it's a little messy - as imstuck said this vi is something that I slapped together quickly to manipulate data. I did the loop go once with a constant try to eliminate the sources of error.

  I fixed it just now. I had the file I tried to load open in excel and closing excel solved the problem. I don't know if this is a common problem with labview (it happens at all when I have the files to open with Notepad).  In case someone else has this problem, close the excel document fixed it completely.

• Replace the index of an array with strings values

  I have a control table 2D (or indicator) CH x T: each cell of the table contains the voltage check for channel and time represented by the respective row and column.

  I would like to be able to scroll the data showing the names and time values to the Index screen instead of numeric values.

  For example, instead of see 0,1,2,3 etc. as line index values, I would like to see channel 1, canal2, canal3 etc..

  Is - it somehow possible?

  Any idea is welcome!

  Thank you in advance!

  See you soon.

  If you want to display the data in the form of a 2D array, but use channel & time as the Index display, you can use the rings of text and structure of the event.  You can reduce the table view if you only want to display one value.

• exception in getting the blob into byte]

  HY guys,.
  I have a problem with my java application.
  I use hibernate to interact with a derby database.
  I've stored an image into the blob field (and not a problem).
  When I try to get the blob into byte array that I have this exception:

  java.sql.SQLException: You cannot invoke other java.sql.Clob/java.sql.Blob methods after calling the free() method or after the Blob/Clob's transaction has been committed or rolled back.

  To get the BLOB I made

  Blob cThumnb = ((Allegato) cAllegati.get(i)).getThumb();
  byte[] cPrev = toByteArray(cThumnb);

  where
  

  private byte[] toByteArray(Blob fromBlob) {
          ByteArrayOutputStream baos = new ByteArrayOutputStream();
          try {
              return toByteArrayImpl(fromBlob, baos);
          }
          catch (SQLException e)
          {
              throw new RuntimeException(e);
          }
          catch (IOException e)
          {
              throw new RuntimeException(e);
          }
          finally
          {

      }
  
      private byte[] toByteArrayImpl(Blob fromBlob, ByteArrayOutputStream baos)  throws SQLException, IOException
      {
          byte[] buf = new byte[4000];
          
          InputStream is = fromBlob.getBinaryStream();
          try
          {
              for (;;)
              {
                  int dataSize = is.read(buf);
                  if (dataSize == -1)     break;

          {
                  throw ex;

              }
          }
                  return  buf;// baos.toByteArray();
      }

  Could you help me?
  I define also autocommit to false.
  Thank you
  Concerning

  java.sql.SQLException: you can't call other methods of java.sql.Clob/java.sql.Blob after the free() method is called or after the transaction of the Blob/Clob object has been committed or rolled back.

  So invoke it before calling the free() method or until the transaction has been committed or canceled?

  And why the blob in an array of bytes to all? The idea of blobs is you don't know what size they are and how you treat the content as a stream.

• Array of strings of text written in the worksheet in LabView 8.0

  Hello

  I've used LabView 8.5 to perform the next action, but as I am now working on another system I'm currently forced to use LabView 8.0 (Windows XP) and would like to avoid the upgrade to LV8.5 +. However if I can't do the following so I'll have to!

  I am wanting to create a worksheet and I use the 'Write to worksheet File.vi' block in LabView. However, as I want to have included column headers, I build an array of strings using the block 'building the table '. This table is then injected into the entry "1 D data" on the block "write to the worksheet. The format for the spreadsheet block is defined by a string with '%s' to enter the entrance of "Format". In LV8.5, the table connects well, but in LV8.0, when I connect the output of the array of strings to the 1 d data entry, the wire becomes broken. The same happens when I use the 2D data entry.

  If I don't do something wrong, how can I put headers in my spreadsheet file? Is it possible in LV8.0, or should I upgrade?

  Thanks for the help!

  There are also detailed instructions on the block diagram of the writing on a file spreadsheet on how to modify it to write strings. Be sure to save it under a new name and in a new location.

• Simulation read data file (*.) (DAT) by using the worksheet (file reading eror - zeros)

  Dear OR community,

  IM pretty new in LabVIEW, so I have a few broblems with reading the data.

  I take a screenshot and mark a problem like part - A and part b below:

  

  The description of the goal:

  I do a mathematical simulation, using the old software whitch exporting results as shown in 1... DAT file, as it shown in the picture (Notepad).

  First of all I need not read these data then I need to draw the graph XY.

  Description of the problem:

  I created a LabVIEW program and im using a funciont reading of spreadsheet per section B - but when im trying to read data im getting all zeros...

  so I can't identify my problem... What is the problem?

  I try different file to read its Case_test_working.txt and everything is good with this data but when im trying to read *. DAT file zeros is array...

  I tried to use seperator different symbols, also try to imort data to exel then export to *.scv, *.txt formats, but the performance was the same as that indicated in part-A.

  Whenever I get zeros, but not a results as in *. DAT or another file format exported with the same data.

  Please be respectifull and understand that im still newbie in labview but I think its excellent software of filtering of the analysis of data and calculations, so I want to master this software for my future use.

  Respectfully,.
