• How to convert an array of string elements to a cluster with elements named different data types?

  I'm looking for more help with the conversion of an array of elements of the chain in a cluster containing elements named different data types.

  I am importing data from an Excel worksheet.  He is coming in LabVIEW as separate (channels) 3 tables: 1) Variable name, (2) three possibilities Int, double, String) data type and the value 3), with the clues in each table corresponding to a separate variable (I have about 180 variables to import).  My ultimate goal is to convert the string array of 'Value' in a cluster.  But I want the correct data type in the cluster and I also the elements of the cluster name to match with the string 'Variable name' table so that I can use the Unbundle based on the name in my main VI.

  Please see attachment a Subvi for more details.  I did the size of the new items of tables 5 for simplicity.   I realize that labels property cannot be changed during execution and I don't think I need to do.  I just want to use the production cluster (mainly the unbundle by name) to help design my main VI.  I will need to 'read' and 'write for' the cluster during execution, but I won't need to change the names of the items.

  I was also wondering if there is a better way to import data from Excel?  Is it possible to import directly into a cluster immediately rather than put everything as strings?  I have attached a Subvi showing how I currently bring in data (found on the forum somewhere).  It comes as table 2D, which I divided into 3 separate tables that I mention above.

  I am open to any suggestion.  Thank you very much.

  Instead of trying to create a cluster, I think I would use only variant attributes.

  

• How to convert numbers to the string with an optimal number of numbers?

  Hello.

  I'm doing something that seems just, and I wonder how much trouble I have with this.  I'm sure there is a way to get LabVIEW for this.

  I have a table of numbers (double), and I use the 'Worksheet picture String' function to generate a string that I can write to a file.

  The problem I have is I want to make the chain to omit useless zeros after the decimal point, but I don't want to limit the accuracy of the numbers that requires it.

  For example, if my data is as follows:

  0.02

  0.4476

  -0.0244570001

  I would like for the string I can be exactly like what I wrote above.  However, depeding on the format string that I use, that's what I get:

  format string: %.10f

  0.0200000000

  0.4476000000

  -0.0244570001

  format string: %f (it seems that by default 6 figures)

  0.020000

  0.447600

  -0.024457

  format string: %.4f

  0,0200

  0.4476

  -0.0244<= all="" trailing="" digits="" for="" this="" number="" have="" been="">

  Anyone know what the format string should be to get the string I want to (what is this

  0.02

  0.4476

  -0.0244570001

  Thanks in advance,

  Alejandro

• How can I convert blob to string xml?

  Hi all
  
  I need help to read an xml string longer than 4000 in the stored procedure.
  
  CREATE OR REPLACE PROCEDURE PROD. InsertFDataBlob(V_MYBLOB BLOB) AS
  
  BEGIN
  
  ........
  
  from SYS. XMLTYPE (V_MYBLOB)
  
  .......
  
  I couldn't find a simple way to convert my blob value that is V_MYBLOB to varchar. Are my versions of database 10g and 11g.
  
  
  Thank you.

  We don't need all this.

  The XMLType object already provides a builder working directly on a BLOB.
  Just pass the ID of the set of characters in addition to the binary content:

  For example, if the content is encoded in UTF - 8:

  ...
  passing xmltype(V_MYBLOB, nls_charset_id('AL32UTF8'))
  ...

• How to convert the Ascii string containing hex to hex string info?

  Dear all,

  I am busy doing a control/reading program for pumps of ISCO.

  Right now I'm in trouble with to send orders for PUMPS in HEXADECIMAL. When I use a CONTROL to the STRING in HEX display, everything works fine (when I manually write down the command in the control of the chain).

  Exist it a couple of pieces order: string Destination, length, ordering, Checksum. I'm doing a sup - screw that automatically calculates the checksum (modulo 256) and adds it to the string. Everything is going well: first of all, I shared the ascii bytes command and I calculate the checksum and add as ASCII HEXADECIMAL value to the chain of command. Also a CR (= 0d) is added. Now the whole string must be converted to hex. The string contains the right nummers HEX, but they are in ASCII format. Here was I feel worth it, I don't know how to do it!

  So to summarize:

  I have an ascii string that contains the values HEX (for example 315230303652454D4F544531420D) and it must be converted to a HEX string (for instance 3152 3030 3652 454 4531 420 4F54) for the pump of the ISCO can understand the command.

  The VI is attached.

  Thank you in advance,

• How to convert the string with numbers in the table of Boolean 2D

  Hello

  I have input a string with comma separated numbers 1,192 (starting at 1).

  This string must be converted to a table 2D-boolean. Each number that appears should be true, not true rest.

  The 2D table consists of 4 times of 0.47 Boolean values.

  1.48--> [0.47] numbers [0]
  49.96--> [0.47] numbers [1]
  Numbers 97.144--> [0.47] [2]
  145.192--> [0.47] numbers [3]

  If a '1, 49, 97 145' input string put all [0] [0.3] true.

  How can it be easy/fast resolved?

  Thanks for help

  Break the string of numbers in a table of numbers.  (Spreasheet String to Array).

  In a loop For, index with each issue of this table.  Use in the range and Coerce to see if it is in the range of numbers.  (You can put this in a loop For as auto good indexing through the ranges).  If it's in the range, then use subset replace table to activate the corresponding item in a real.  If this is not the case, do nothing.  Maintain the table of Boolean in a shift register.

  Repeat this step for each number in your table.

  Use Integar.parseInt (). But make sure your str contains the integer value (like str = '123') otherwise you will get the exception.

  String str = "123"; int num = Integer.parseInt(str);

• How to create an XML Document and convert it into a string? (send through wireless network)

  Hello

  I am now able to post data to a web server by using Blackberry JDE (medical use).

  Now, instead of display the plain text, I would like to send an XML file.

  I am able to do it using this code on a 'normal ': Java application

  import java. IO;
  Org.w3c.dom import. *;
  Import javax.xml.parsers. *;
  Javax.xml.transform import. *;
  Javax.xml.transform.dom import. *;
  Javax.xml.transform.stream import. *;

  public class {XML
  Public Shared Sub main (String [] args) {}
  try {}
  DocumentBuilderFactory plant = DocumentBuilderFactory.newInstance ();
  DocumentBuilder builder = factory.newDocumentBuilder ();
  Doc document = builder.newDocument ();
             
  Root element = doc.createElement ("root");
  doc.appendChild (root);
             
  Child element = doc.createElement ("child");
  child.setAttribute ("name", "value");
  root.appendChild (child);

  Add a text element to the child
  Text = doc.createTextNode ("text");
  child.appendChild (text);

  implement a transformer
  TRANSFAC TransformerFactory = TransformerFactory.newInstance ();
  Transformer trans = transfac.newTransformer ();
  trans.setOutputProperty (OutputKeys.OMIT_XML_DECLARATION, 'yes');
  trans.setOutputProperty (OutputKeys.INDENT, 'yes');

  create the string of the xml tree
  StringWriter sw = new StringWriter();
  StreamResult result = new StreamResult (sw);
  DOMSource source = new DOMSource (doc);
  TRANS. Transform (source, result);
  String xmlString = sw.toString ();
  System.out.println (xmlString);
  } catch (Exception e) {}
  make error management
  }
  }
  }

  However, on the Blackberry JDE, many functions is not recognized.

  I saw the class DocumentBuilderFactory (net.rim.device.api.xml.parsers.DocumentBuilderFactory), the DocumentBuilder (net.rim.device.api.xml.parsers.DocumentBuilder) class and the interface of Document in the docs of Blackberry Java (4.2.1).

  So, I'm able to create an XML Document... but I don't know how to convert to a string?

  How can I do this? The TransformerFactory class doesn't seem to exist... and I did not find an alternative yet.

  At the present time, here is the code I use to publish data:

  String coord = lat + ";" + LNG; post data
  con = (HttpConnection) Connector.open (url); Open the connection URL
  con.setRequestMethod (HttpConnection.POST); POST method
  con.setRequestProperty ("Content-Type", "application/x-www-formulaires-urlencoded");
  out = con.openOutputStream (); display the results in a stream
  out. Write (Coord.GetBytes ());

  responseCode = con.getResponseCode (); Send data and receive the response code
  If (responseCode! = HttpConnection.HTTP_OK) {}
  System.out.println ("HTTP STATUS CODE: 404"); error
  } else {}
  System.out.println ("HTTP STATUS CODE: 200"); successful
  }
  If (con! = null) con. Close; close the connection to the URL

  As mentioned, rather than display a string with a delimiter between each value (there will be a lot more than two values finally), I would like to publish an XML.  It will be more "elegant" and easier to parse by my code on the web server.

  Maybe I don't have to convert it to a string?

  In other words, how can I convert my XML Document to send it via the wireless network?

  Thanks for your help!

  TransformerFactory does not exist in the BlackBerry API.  As far as I can tell, you need to implement yourself.  You can do this by walking the DOM and the output of channels.  They have an example of the market of the DOM in the XMLDemo, but they view as fields, you just need to write strings.

• How to convert string input streams

  Can someone tell me how to convert string input streams...

  There are multiple ways. I will list down few of them.

  With the help of the old solution and standard java.
  

  publicstaticString fromStream(InputStream in)throwsIOException {    BufferedReader reader =newBufferedReader(newInputStreamReader(in));    StringBuilder out =newStringBuilder();    String line;    while((line = reader.readLine()) !=null) {        out.append(line);    }    returnout.toString(); } returnsb.toString();

  If you use Google-Collections/guava-

  InputStream stream = ... String content = CharStreams.toString(newInputStreamReader(stream, Charsets.UTF_8)); Closeables.closeQuietly(stream);

  If you use the common Apache library... then it is worthwhile.

  StringWriter writer =newStringWriter(); IOUtils.copy(inputStream, writer, encoding); String theString = writer.toString();

  Quick way but only work during deserialization.

  String result = (String)newObjectInputStream( inputStream ).readObject();

  Note: ObjectInputStream is on deserialization and the flow of data must respect the Protocol of serialization to work, which may not always true in all cases.

  Ultimately, the most effective solution and only in two lines using java class Scanner.

  Tricky is to remember the \A regex that matches the beginning of the entry. It actually indicates Scanner to mark all of the flow, from start to beginning next (illogical).

  publicstaticString convertToString(InputStream in) {    java.util.Scanner s =newjava.util.Scanner(in).useDelimiter("\\A");             returns.hasNext() ? s.next() :""; }
