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 URLAs 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.

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.

convert StreamConnection to a string
How can I convert an xml StreamConnection that is returned by an http call to a string?
Now I give the floor:
fconn = (StreamConnection) Connector.open (xmlUrl);
which returns xml code. I analyze the XML & it works great.
I also want to save the xml string.
Thank you
It will be easier to use:
InputStream is = fconn.openInputStream(); byte[] streamBytes = IOUtilities.streamTobytes(is); String str = new String(streamBytes);
It's only for the stream to be part of the code string conversion.

Convert an array of strings 1 d
Hello
I am creating headers in a write to a text file. Attached, it's my code and the file looks like when opened in Excel. I have my data in three columns, but the headers are not where I need them.

Thank you
Something like that.

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 to convert boolean 1 d table to leave everything in a loop?
I had initially a > = block to get out of this while loop and it worked fine. I wanted to add a second condition to exit the while loop, using a > = block, so I run both in a block of GOLD, and I get a cut wire. I don't understand why one works but the other does not.
The background does not work with or without the block of GOLD.
If your goal is to stop based on the GOLD of the two State, more than 720 'OR' any value that is greater than or equal to 0.5, you will need to 'OR' the picture coming out of equal or greater than 0.5.
