Hi jeyanthi,
if you connect your array to the "Concatenate Strings" function, then you get what you want.

How to auto divide a one-line string into several rows in jsf?
<h:outputText value="#{msgs.aim}" styleClass="content_text_darkblue"></h:outputText>
for example, the #{msgs.aim} will be a long string that one line cannot output. how can i make it auto-break according to the row length instead of show a horizontal scrollbar?
in raw html code, i know i can include the content inside a <p> tag. but in jsf, i found it impossible to do in this way, although i tried to use <f:verbatim> tag
can any1 give me some idea about this?Hello,
Why not <h:inputTextarea> ? It makes this automatically for you and you can user readonly="true" to render it as a fictive outputTextarea...
See example:
<h:inputTextarea value="#MyBean.description}" rendered="true" required="false" rows="20" cols="80" id="description" readonly="true" />
Hope you agree.

Reading one line from a text file into an array
i want to read one line from a text file into an array, and then the next line into a different array. both arays are type string...i have this:
public static void readAndProcessData(FileInputStream stream){
InputStreamReader iStrReader = new InputStreamReader (stream);
BufferedReader reader = new BufferedReader (iStrReader);
String line = "";
try{
int i = 0;
while (line != null){
names[i] = reader.readLine();
score[i] = reader.readLine();
line = reader.readLine();
i++;
}catch (IOException e){
System.out.println("Error in file access");
this section calls it:
try{
FileInputStream stream = new FileInputStream("ISU.txt");
HighScore.readAndProcessData(stream);
stream.close();
names = HighScore.getNames();
scores = HighScore.getScores();
}catch(IOException e){
System.out.println("Error in accessing file." + e.toString());
it gives me an array index out of bounds erroroh wait I see it when I looked at the original quote.
They array you made called names or the other one is prob too small for the amount of names that you have in the file. Hence as I increases it eventually goes out of bounds of the array so you should probably resize the array if that happens. -
I was wondering if someone could tell me how to take a multi-line
string and dump it into an array. I'm assuming that I use the 'Pick
Line' function in a while loop? What do I check for to terminate the
loop?
Thanks...

How do I input multiple numbers to go to multiple variables in one line?
I was wondering what I had to do to input 5 variables on one line. I have the program running fine, but I'm stuck at the part where it says "The numbers will be input five per line, on four lines".. Aside from poor grammar, it doesn't make any sense to me. Here's the whole question:
Write code that will fill the array twoDArray(declared in the line of code below) with numbers typed in at the keyboard. The numbers will be input five per line, on four lines. Use the following array declaration:I don't need any immediate help with the array itself, just the input (unless the input is directly related to the array). Just in case, I'm going to post my code. This is still very messy, because I'm not done, and it's might be somewhat sloppy as I'm new to 2d arrays (in java).
Thanks for the help.
import java.io.*;
class darrays
public static void main(String[] args) throws IOException
InputStreamReader inStream = new InputStreamReader (System.in);
BufferedReader stdin = new BufferedReader(inStream);
int[][] twoDArray = new int[4][5];
int x,y;
String input;
for (x = 0; x <= 3; x++)
for (y = 0; y<=4; y++)
input = stdin.readLine ();
twoDArray[x][y] = Integer.parseInt (input);
for (x = 0; x <= 3; x++)
for (y = 0; y<=4; y++)
System.out.print(twoDArray[x][y] + " ");
System.out.println("");

When I was learning Basic (good old Kemeny & Kurtz style, when Basic was simply a simplified Fortran, not Bill Gates style) you simply have to write
READ A, B, C, D, E
DATA 10, 20, 30, 40, 50
or something like
INPUT "A", A: INPUT "B", B etc.
In Java you are required to handle the mysteries of StringTokenizer...
Java 1.5 is promising to make it easier:
Scanner sc = Scanner.create(new File("myNumbers"));
while (sc.hasNextLong()) {
long aLong = sc.nextLong();
}where you get the longs (decimal formatted, separated with blanks) from a text file.
But not so easy as the good old INPUT statement.
Even C's scanf is not so easy, because has lots of subtleties
(when you finally mastered the esoteric art of using char* as strings, you are really fed up of char* strings, because they usually blow up due to buffer overflows or mere programmer errors, and start to use Java instead, even having to master the StringTokenizer and other classes.). -
Originally had a program to input 5 numbers then put into an array and sort in order. I used seperate lines for each inputted number but want to get the user to put all five numbers on the same line therefore reducing the amount of code. For this I've used args[0] to args[4] as the five different numbers but I now get an arrayindexoutofbounds exception. I can't see where the difference is from the first program to this new one. It's probably an oversight somewhere. Any ideas?
Thanks,
Chris

How to get the results in one line
Hi
if i use the script below i get the name of path and then : and in next line i get the results.is there a way to get the results from every path after the : and not in the next line?
another question - is there a way that the script will not show the server name on every path?
(Get-Counter -ListSet LogicalDisk).PathsWithInstances | Get-Counter
THCIf you take you script and pipe it to get member, it will give you a list of various script properties.
(Get-Counter -ListSet LogicalDisk).PathsWithInstances | Get-Counter | get-member
You will see that the object type returned by "Get-Counter" is Microsoft.PowerShell.Commands.GetCounter.PerformanceCounterSampleSet.
TypeName:
Microsoft.PowerShell.Commands.GetCounter.PerformanceCounterSampleSet
Name MemberType Definition
Equals Method bool Equals(System.Object obj)
GetHashCode Method int GetHashCode()
GetType Method type GetType()
ToString Method string ToString()
CounterSamples Property Microsoft.PowerShell.Commands.GetCounter.Perfo...
Timestamp Property datetime Timestamp {get;set;}
Readings ScriptProperty System.Object Readings {get=$strPaths = ""...
You can try grabbing different properties, and they will print out differently, displaying the data on the same line in some cases. For example, pipe your output to a "foreach-object" block, and then for each object print out the CounterSamples property.
(Get-Counter -ListSet LogicalDisk).PathsWithInstances | Get-Counter | foreach-object { ($_).CounterSamples }
This should all print on one line now. However, you also asked if there was a way to not have the server print out on every line. The way to control the format of these outputs is to use the "format-table" cmdlet. So you would pipe your output to format-table
and then give it various options. This is how you would pipe it (without any options).
(Get-Counter -ListSet LogicalDisk).PathsWithInstances |
Get-Counter | object { ($_).CounterSamples | format-table }#OR USE YOUR ORIGINAL CODE(Get-Counter -ListSet LogicalDisk).PathsWithInstances |
Get-Counter | format-table }
Now, it's up to you to give format-table the options you want. With no options, output will look unchanged. To see what options are available to you, use get-help.
get-help format-table
I hope this helps!
Thank for all the info... -
About combing two array into one
Hi all,
I post a questiona bout converting an array of integer into char (byte) array and I got a solution already http://forums.ni.com/t5/LabVIEW/how-to-display-char-code-properly/m-p/2596087#M780368
However, I enouther another problem while dealing with an array of U16 type. I would like to extract the high and low byte from numbers (U16) stored in array. I extract the high and low byte for each U16 number and convert them as char, concatenate them to a string. Repeat this process for each element in the array so to get a big string with each element is a char for high and low byte. My code is enclosed as follows
It works fine but I am concerning the speed. Is that any other way to do it fast and don't use loop (in real case, I will deal with pretty big array many times, efficiency is a problem). Note that the high and low bytes array extracted from the original array with the module Split number.vi, but how can I combine these two array in one code with data arranged as high-low-high-low ... ? Thanks.
Solved!

You need to be more clear.
Looking at the code, you are dealing with I16, not U16. Also your index array primitives could be replaced by autoindexing. Your use of the feedback node only makes sense if you want to append strings forever with stale data, thus growing data structures without limits. If you only want to convert the current data, remove the feedback mode and use a "concatenate strings" with a single input. A for loop is one of the most efficient data structures and using it is not a problem. One way or another the code needs top oerate on all data.
All that said, I agree with Tim that most likely all you need to do is insert a typecast after the "to I16" and eliminate all other code.

I have a labview sub-VI reading the string being outputted by a pH meter. The meter outputs a 5 line string and labview is only reading up to each lines carriage return, there-by giving me 5 separate strings is there anyway to rectify this and have the 5 line read as one string?

Labview 2010Yes, LabVIEW will automatically update. What happens is that the old serial functions still exist in 7.1 and above but the code (the block diagram) has been modified to use VISA functions. Older versions of LabVIEW are fully supported in this manner. The only way you can avoid the automatic update is to have the old serial functions in an llb and your top level VI refer to these. Having any VI that was part of vi.lib in an llb is a very bad idea and the way to fix things is to remove any VIs in the llb that are part of the LabVIEW distribution.
I don't remember how the old serial config worked and what the new version does with the VISA Configure Serial Port. Your program should only have a single serial config and you might just be able to directly replace that with the VISA configure Serial Port. -

'Calendar UI' which will display current month's calendar in one line
Hi Experts,
I have to create a calendar in following way. Here I have to display calendar of current month for the employee. The entire month detail has to appear in one line. In fact it is needed for Leave Overview iView.
Manager needs to view the Leave details of all employees working in his department
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31
Mon Tues Wed Thurs Friday Sat Sun

I am not sure how to do it? Do we have any ready made UI element which we can use. I can see Date navigator. However it
displays the calendar in 4 rows.
Please help.
Regards,
GaryHi Abhinav, Experts
Thanks. The design of my RFC will be like this:
1) Input Org Unit, Month, Year
2) Output
Pernr (datatype number 8)
Name (datatype string)
Day1 (datatype string)
Day2 (datatype string)
Day3 (datatype string)
Day4 (datatype string)
Day29 (datatype string)
Day30 (datatype string)
Day31 (datatype string)
3) The default value Day1, Day2 etc will be null
4) I will find out Leave Details. If Leave has been approved for say Day5 then I will populate Day5 = 'AP'.
5) I will write another logic to make the color of cell as 'Green' for Day5.
6) In Feb 2011, there are 28 days. There will be another logic to make the Day29, Day30, Day31 invisible for months like Feb 2011.
Please let me know if this approach is correct.
Please also let me know how to display day i.e. 01.04.2011 is Friday. In Calendar I have to display
1.4.2011 2.4.2011 3.4.2011
Friday Saturday Sunday

I want to add one line at a time in listbox/textbox just like InsertTextboxLine funtion in CVI. I can not find similar VI in labview. I think I can do it long way...by saving listbox to an array then append my line at the end of the array and send updated array to listbox..these are lot of steps to add one line to listbox/textbox...
Any help would be appreciated.
Thanks.
CVI 2010
LabVIEW 2011 SP1
Vision Builder AI 2011 SP1Actually, the way to append an item to a list box is to create an Item Names property node for the list box. Then you can use Insert Into Array, and write to another property node for Item Names.

How to do the multiple-line String at JList? help!
i need some code to multiple-line String at JList.
i know that it is can be done by html code.
example:
<p>line1</p><p>line2</p>
but if i use that html code...
i face another problem to my JList..
it cannot set the font use the ListCellRenderer..
like:
public Component getListCellRendererComponent(
JList list,
Object value,
int index,
boolean isSelected,
boolean cellHasFocus)
Color newColor = new Color(230, 230, 230);
setIcon(((DisplayItem)value).getIcon());
setText(((DisplayItem)value).getChat());
setFont(((DisplayItem)value).getFont());
setBackground(isSelected ? newColor : Color.white);
setForeground(isSelected ? Color.black : Color.black);
if (isSelected) {
setBorder(
BorderFactory.createLineBorder(
Color.red, 2));
} else {
setBorder(
BorderFactory.createLineBorder(
list.getBackground(), 2));
return this;
all my JList will be html type...
i don't want that happen..can be another method to do that multiple-line String in JList??
i also need to set a icon image between string in the JList. anyone get idea??
i need ur help!
thank you.I think you should create/override several methods like setText(String), setIcons(Icon[]), paintComponent(Graphics), getMinimumSize(), getPreferredSize(), etc.
I would like to code like below...:class MultilineLabel extends JLabel {
private String[] text = null;
private ImageIcon[] icons = null;
public void setText( String newText ) {
// It overrides JLabel.setText( String )
// Tokenize newText with line-separator
// and put each text into the 'text' array.
public void setIcons( Icon[] newIcon ) {
// It is similar to JLabel.setIcon( Icon ) method,
// but it receives an array of Icon-s. Set these icons to 'icons' variable.
public void paintComponent( Graphics g ) {
// It overrides JComponent.paintComponent( Graphics ) method.
super.paintComponent( g );
if ( text != null && icons != null ) {
int icon_x = 0;
int text_x = 0;
int y = 0;
// draw customized content..
for ( int i=0; i<text.length; i++ ) {
// compute x and y locations
// icon_x = ...
// text_x = ...
// y = ...
// and draw it!
g.drawString( text[ i ], text_x, y );
icon[ i ].paintIcon( this, g, icon_x, y );
public Dimension getMinimumSize() {
int width = super.getMinimumSize().width;
int height = ... // I think you must compute it with 'text' and 'icons'' arrays.
return new Dimension( width, height );
public Dimension getPreferredSize() {
int width = super.getPreferredSize().width;
int height = ...
return new Dimension( width, height );
}I think that code-structure above is the minimum to implement your requirements. (Of course if you want to implement it :)
Good luck and let me know it works or not. :) -
More than one line beside a category icon
Hello,
I have in a page placed the text item category icon, and space a then the display name of the item. The problem is that as the text of the display name is too long when it makes an automatic return makes it under the category icon. It seems to be a problem with the number of text lines that can be placed beside the category icon.
How can I make that the category icon accepts more than one line of text beside it?
Thanks in advance,

From Mac: Customer\tPhoneCustomer 1\t555-555-5555Customer 2\t555-555-5556
From Windows: Customer\tPhone\rCustomer 1\t555-555-5555\rCustomer 2\t555-555-5556\r
This appears to be a bug in a flash.display class as pasting the data from Excel to a text editor and then copying/pasting into the same Flex TextArea preserves the original line breaks.
Has anyone figured out a work around?
