Convertir string recibido por UDP a real

Hola.
Estoy comunicando un PLC con Labview mediante UDP. Consigo mandar dos valores flotantes desde el PLC y ver datos en Labview. El problema es que quedan en modo string y no muy entendibles. Los he convertido a un array de 8 bytes y se ven ya datos numéricos, pero no consigo ahora juntar esos 4 bytes para formar de nuevo el dato en flotante. Sabe alguien como reconvertir esos datos?
Gracias y un saludo.
Solved!

Hola Allende,
No es que las funciones de UDP te
manden strings como tal, sino que es una manera de representar los datos en
binario que están recibiendo por el puerto UDP. Es decir, que lo que llega a
las funciones son chorros de bits que los agrupa en paquetes de 8 bits y
representa esos 8 bits en código ASCII. Para ver el número en flotante, tienes
que convertir esos bits en un número con la estructura de número flotante. Te envío
estos enlaces que te serán de mucha utilidad para darle un formato adecuado a
los bits:

Not able to convert string attribute to number and date please help me out

not able to convert string attribute to number and date attribute. While using string to date conversion it shows result as failure.As I am reading from a text file. please help me out

Hi,
You need to provide an example value that's failing and the date formats in the reference data you're using. It's more than likely you don't have the correct format in your ref data.

Convert String to Date and Format the Date Expression in SSRS

Hi,
I have a parameter used to select a month and year string that looks like:    jun-2013
I can convert it to a date, but what I want to do is, when a user selects a particular month-year  (let's say "jun-2013")
I populate one text box with the date the user selected , and (the challenge Im having is) I want to populate a text box next to the first text box with the month-year 2 months ahead.    So if the user selects
jun-2013   textbox A will show jun-2013
and textbox B will show aug-2013..
I have tried:
=Format(Format(CDate(Parameters!month.Value ),
"MM-YYYY" )+ 2 )   -- But this gives an error
This returns the month in number format   like "8"    for august...
=Format(Format(CDate(Parameters!month.Value ),
"MM" )+ 2 )
What is the proper syntax to give me the result    in this format = "aug-2013" ???
Thanks in advance.

You can convert a string that represents a date to a date object using the util.scand JavaScript method, and then format a date object to a string representation using the util.printd method. For more information, see:
http://livedocs.adobe.com/acrobat_sdk/9.1/Acrobat9_1_HTMLHelp/JS_API_AcroJS.88.1254.html
http://livedocs.adobe.com/acrobat_sdk/9.1/Acrobat9_1_HTMLHelp/JS_API_AcroJS.88.1251.html
In your case, the code would be something like:
var sDate = "2013-01-10";
// Convert string to date
var oDate = util.scand("yyyy-mm-dd", sDate);
// Convert date to new string
var sDate2 = util.printd("mm/dd/yyyy", oDate);
// Set a field value
getField("date2").value = sDate2;
The exact code you'd use depends on where you place the script and where you're getting the original date string, but this should get you started.

Convert String variable value to an Object referece type

Hi all,
I want to know that if there any possible way to convert String variable value to a Object reference type in java. I'll explain by example if this is not clear.
Let's think that there is a string variable name like,
String name="HelloWorld";
and there is a class name same to the variable value.
class HelloWorld
I am passing this string variable value to a method which is going to make a object of helloworld;
new convertobj().convert("HelloWorld");
class convertobj{
public void convert(String name){
// in hert it is going to create the object of HelloWorld;
// HelloWorld hello=new HelloWorld(); just like this.
now i want to do this from the name variable value.( name na=new name()) like wise.
please let me know if there any possible way to do that.
I am just passing the name of class by string variable then i wanted to make a instance of the class which come through the variable value.
thanx.

Either cast the object to a HelloWorld or use the reflection API (Google it) - with the reflection API you can discover what methods are available.
Note: if you are planning to pass in various string arguments and instantiate a class which you expect to have a certain method... you should define an interface and have all of your classes that you will call in this way implement the interface (that way you're sure the class has a method of that name). You can then just cast the object to the interface type and call the method.

Well, for Binding you will probably need to further convert to XMLListCollection or ArrayCollection.
Not sure.
However, that is the way to convert String to XML.

Convert String to java UTC date then to sql date

Hi,
I am trying to convert string (MM/dd/yyyy format) to UTC date time and store in the database.
This is what I did:
String dateAsString = "10/01/2007";
SimpleDateFormat formatter = new SimpleDateFormat("MM/dd/yyyy");
formatter.setTimeZone(TimeZone.getTimeZone("GMT"));
formatter.setLenient(false);
java.util.date dateValue = formatter.parse(dateAsString, new ParsePosition(0));
dateValue will be Sun Sep 30 20:00:00 EDT 2007 in UTC.
Now I need to store this date and time to MS SQL database.
I used the following code:
java.sql.Date sqlDateValue = new java.sql.Date(parsedToDate.getTime());
But this code give only the date, not time 2007-09-30
Can anybody tell me how I can change this java date to sql date (or datetime?) so that I can get both date and time.
Thanks,
semaj

When you say "string of numbers" do you mean an array? What is the specific issue you are having? You seem to have orange wires running all over the place. Give a small example demonstrating the problem.
