How to get the size of a string in bytes

Morning,
I’m trying to get the length in bytes of a string, the characters below are 3 byte UTF-8, but when I display
The length of either int, looks like is double I got 120 and I think it should be 60. Any idea
String requiredMsg = "όόόόόόόόόόόόόόόόόόόό";
int byteCountUTF8 = requiredMsg.getBytes("UTF-8").length;
int byteCountUTF8 = requiredMsg.getBytes().length;
thanks

OK, it is not 'o with acute', but rather 'Greek small omicron with tonos'.
This page may help you sort it out:http://www.fileformat.info/info/unicode/char/3cc/index.htm.
According to the page and to my tests, this Unicode 03CC has a 2 bytes (not 3) UTF-8 representation.
String requiredMsg = "\u03CC";
System.out.println(requiredMsg.getBytes("UTF-16").length);
System.out.println(requiredMsg.getBytes("UTF-8").length);
System.out.println(requiredMsg.getBytes().length); // In WindowsResult on my machine:
4

one interesting observation about vmstat I found out is (mostly on Solaris)
the first line of information always off chart, so I usually do a few interval to get constant result.
if you use linux
just
cat /proc/meminfo

How to get the size of partition?

The following SQL will get the rows of the fact table & aggregation. But how to get the size (MB) of the partition. select * from $system.discover_partition_stat That should be doable, because in BIDS, we can see the size of a partition, but from which
view we can do that?

This is the best bet you have SELECT * FROM SystemRestrictSchema($system.discover_partition_stat ,DATABASE_NAME = 'Adventure Works DW' ,CUBE_NAME = 'Adventure Works' ,MEASURE_GROUP_NAME = 'Internet Sales' ,PARTITION_NAME = 'Internet_Sales_2003') Refer

How to get the size of a hard disk?

Hi,
As above, how to get the size of a hard disk by using Java.
Thanks you!
Alex

I would be interested in the answer of this question, too.
In core Java there is no way to find it out in a platform independent manner because of the hardware abstraction of the VM. So my only idea is to write a native library for doing this and colling it via JNI

How to measure the size of a string

windows app store how to measure the size of a string?
string str = "Hello word windows app store";

if you need the actual width the string occupies in pixels than use (see
this MSDN link for more details):
Graphics.MeasureString(String, Font)
if you only need the "length" of the string i.e. no. of characters than use (see
this MSDN link for more details):
str.Length
dont forget to bing / google :)
hope this helps!
Graphics.MeasureString(String, Font) can not use in windows store app.
TextBlock has Measure()
method, as following:
Size MeasureString(string content, Size availableSize, double fontSize, string fontFamily="Segoe UI")
    TextBlock tb = new TextBlock();
    tb.TextWrapping = TextWrapping.Wrap;
    tb.Text = content;
    tb.FontFamily = new Windows.UI.Xaml.Media.FontFamily(fontFamily);
    tb.FontSize = fontSize;
    tb.Measure(availableSize);
    return tb.DesiredSize;
Test:
string str = "Hello word windows app store";
Size size = MeasureString(str, new Size(800, 600), 40);

How to get the size of the file

Hi All,
I want to get the size of the file in terms of bytes. I used the following code it returns the value in long how can get it in bytes
import java.io.File;
public class ServerBackupCheck {
     public static void main(String args[]){
          File f = new File("C:/Program Files/Apache Software Foundation/Tomcat 5.5");
          System.out.println(f.isDirectory());
          System.out.println(f.getTotalSpace());
output:
true

regards,
Maheshwaran Devaraj

if it is a folder you can use this recursive algorithm
public static long recurse(File f) throws IOException
          long bytes = 0;
          File files[] = f.listFiles();
          for(int i =0 ;i<files.length;i++)
               File file = files ;
               if(file.isFile())
                    FileInputStream fis = new FileInputStream(file);
                    byte[] by = new byte[fis.available()];
                    fis.read(by);
                    bytes = bytes + by.length;
               if(file.isDirectory())
                    bytes = bytes + recurse(file);
          return bytes;
System.out.println(recurse(f)); gives you the total bytes....

ADF7,
I'm not sure I understand what you are up to.
As far as I understand you want to get the display value instead of the index
I use this code
    public void StatusChangedListener(ValueChangeEvent valueChangeEvent)
        BindingContext lBindingContext = BindingContext.getCurrent();
        BindingContainer lBindingContainer = lBindingContext.getCurrentBindingsEntry();
        JUCtrlListBinding list = (JUCtrlListBinding) lBindingContainer.get("Status");
        int newindex = (Integer) valueChangeEvent.getNewValue();
        Object row = list.getDisplayData(); // Wichtig um die liste zu laden!!!!
        Row lFromList = (Row) list.getValueFromList(newindex);
        Object lAttribute = lFromList.getAttribute("Value");
        String newVal = (String) lAttribute;
    }to get the value from a selectOneChoice component...

How to get the size of the cuurrent illustration

Sorry, I made a mistake before this one. The questios is this: can anybody tell me how can I get the size of the current illustration, (as oposed to the page size) in points. Something like 120 points wide and 87 points High?. What function do I need to call?

From AI Function reference (included with CS2 SDK):
AIDocumentSetup setup;
error = sDocument->GetDocumentSetup(&setup);
if (error) goto processError;
writeDocumentSetup( &setup );
The AIDocumentSetup record returns the following information:
typedef struct {
AIReal width, height;
AIBoolean showPlacedImages;
short pageView;
AIReal outputResolution;
AIBoolean splitLongPaths;
AIBoolean useDefaultScreen;
AIBoolean compatibleGradients;
AIBoolean printTiles;
AIBoolean tileFullPages;

How to get the size of the test put in a JPasswordField ?

I've checked all the methods that may allow me to know the size
of the text in a JPasswordField.
I tested getCaretPosition() , getSelectedEnd()
and they don't satisfy me : they give the current position of the cursor
and not the size of the text typed. The only safe method is the use
of the method getText() which is deprecated, so that i can get the
size of the resulting String.
Is there a method that allow to know the size of a char arrays ?
Any help will be welcome, thanks.

JPasswordFieldObj.getPassword().length;the length variable isn't visible in the forte visual parameters.
thanks a lot, it saved me a lot of time and let me keep the
getPassword() secure.
Sorry, don't have more duke dollars, but you should have get some for this.

How to get the size of file

Hi
I want to know the size of the file from Java. ie If i have 10 lines in that file each of 15 characters
then 10 *2*10=200Bytes is the size. How will i get this?
More over, if i am reading the 4 the line, how will get the info that I have read 3 lines =3*2*10= 60 bytes so far?
Regards
Sriram

This is from the JavaDocs on java.io.File
length
public long length()
Returns the length of the file denoted by this abstract pathname. The return value is unspecified if this pathname denotes a directory.
Returns:
The length, in bytes, of the file denoted by this abstract pathname, or 0L if the file does not exist
Any of the read methods (except readLine()) on the many stream objects return the number of bytes read, simply accumulate these returns to know how many bytes have been read.

How to get the system date format string?

Hello, everybody!
I want to create a MaskFormatter with a mask for dates. So, I could suply as the constructor parameter: "##/##/####'. However, what if the year comes first in the current system date format settings, or the month is in the second place or in the first?... So, I can't just suppose that the current locale format for dates is like the one above. So, my question is: is there a way to get the SYSTEM DATE FORMAT STRING in Java? Searching in google I saw that this was already asked in this forum:
http://forum.java.sun.com/thread.jspa?threadID=301034&messageID=1193794
but there was no effective answer. Does someone already know how to get this?
Thank you.
Marcos
