How to get the index of Mult column list box

Hello all,
I need small help. Please help me.
Is there is any property to change the "Multi column list box" row index position dynamically?
I want to change the index position at runtime like below.

It's called Top Left Visible Cell. There aren't that many properties there.

Is there a way to find out how to get the index of a column?

Hello,
I want to know the index of a column for example the column at the first position in a jtable is 0 so how can i get this index?
for example: the column called "surname" is index 0 but the user can move the column. So the name stays the same but the index of the column changed. I search for a method like
table.getColumnIndex("surname");

I think it really depends on what the OP is trying to do. I think the program
below offers up the possible choices pretty well.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.table.*;
public class TableColumnIndexDemo extends JFrame {
     private JTable table;
     private String[] names = new String[]{ "One", "Two", "Three", "Four", "Five" };
     public static void main( String args[] ) {
          SwingUtilities.invokeLater( new Runnable() {
               public void run() { new TableColumnIndexDemo(); }
     public TableColumnIndexDemo() {
          setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          DefaultTableModel model = new DefaultTableModel( names, 1 );
          table = new JTable( model );
          JButton button = new JButton( "Print indices" );
          button.addActionListener( new ActionListener() {
               public void actionPerformed( ActionEvent e ) {
                    printIndices();
          getContentPane().setLayout( new BorderLayout() );
          getContentPane().add( button, BorderLayout.NORTH );
          getContentPane().add( new JScrollPane( table ), BorderLayout.CENTER );
          getContentPane().add( new JLabel( "Move columns around then print indices" ), BorderLayout.SOUTH );
          setSize( 300, 150 );
          setVisible( true );
          printIndices();

          StringBuffer sb = new StringBuffer();
          System.out.println( "Visible order");
          for ( int k = 0; k < columnModel.getColumnCount(); k++ ) {
               if ( k > 0 ) sb.append( ", " );
               sb.append( k ).append( " " ).append( columnModel.getColumn( k ).getIdentifier() );
          System.out.println( sb );

How to insert data to the specified row column of the multi column list box

Hi All
How do i insert data into the specified column of the multi cplumn list box?
I have a table that containsall station nos and name.Then another table contains the data the various stations having at for 24 hrs.That is 12 am to 11 pm.
And i want to display each stations details as follows using a multi column list box/table
My stationinfo table
stnno   stnname......................
s1           stn1
s2            stn2
s3             stn3
The other table
stnno      sysdatetime       data
s1             12am                   1
s2              12am                   4
s1               1 am                 2
So the station s1,s2.... will have data for 24 hrs.
And i want to display it as follows using a multicolumn listbox
stnname        12am   1 am ......................................11pm
s1                   ...................
s2                 ........................
What i have in my mind is to get all station nos
and in a for loop get the station's data from 12 am to 11 pm
or
select every statios data for each hor.But in this case i have to query the database 24 times.So i dont think its a good way.
Or any other better query available?
Can anybody suggest me a good idea?

Second time it shows the value two times (i.e) First time submitted value and the second time submitted value. After that it works fine.. I have problem while clicking first time only..
The Following error also raises.. One multiselect is dependent on other multiselect.

How to extract information in cells of a mult-column list box?

I have multi column list box. At run time this listbox allow me to select entire row (this is fine), how to extract the data from each cell along the selected row? It seems to me that the Multi column Listbox (MCL) is merely a 1D array (I guess index of this 1D array corresponds to row index of the MCL and value of the element corresponds to column index of MCL.)

To extract cell values of the selected row, you can create a property node for the MCL. From this property node, choose "Item Names". This is a 2D array containing all cell values. Index this array with the MCL terminal. Note that you must choose the scalar data type for the MCL. To choose the scalar data type, right click on the MCL and go to "Selection Mode"->"Data Type"->"Scalar".
See attachment written with LabVIEW 6.
I hope it will help you.

How to prevent multi-column list box showing an extra column

I am using a multi-column list box to display data and to allow the user to enter new values. More columns are used than are actually displayed within the bounds of the listbox control. Using an event structure the user is able to scroll left and right along the columns of the list box to select the appropriate field. I am using the 'Edit Position' property to highlight the particular field that the user is selecting. This technique works well and the listbox scrolls left and right to display the selected fields correctly.
If the listbox has, say, 10 columns with only 5 being visible within the displayed width, then I clamp the Edit Position to a maximum column value of 9 to prevent the list box from continuing to scroll right into unused columns. This works fine, except that when the user scrolls to the 10th column, the listbox control always shows a blank 11th column. The 11th column cannot be selected. It would appear that this is default behaviour for the listbox control in that an additional column is always displayed relative to the Edit Position. In my particular application it is untidy to have this blank column appearing. I have tried a workaround by programmatically writing to the 'TopLeft' property of the listbox. This partially works by ensuring that the blank 11th column is never displayed, however, despite the Edit Position being correct to select the 10th column, the field in the 10th column is no longer highlighted and the user cannot enter a new value.
Does anyone know of a method for preventing the blank additional column from appearing?

Ok - I have attached an example which demonstrates the issue. This is produced with LV 2012. Open the project and then the 'Multi column listbox.vi'. Run the vi and use the right/left arrows to move between cells in the listbox. Observe that unused (unwanted) columns are always displayed to the right.
Thanks for any help..

How to get the index of subform in dynamic Forms??

We are creating a Dynamic Form in which there is a field "PAN number" in a block. With the Script, we are replicating the blocks. Suppose there are 10 blocks (hence 10 PAN number fields will be there) and if the user wants to enter the PAN number in any of the blocks, how can we get the index of the block on which a value has been entered?

Are you sure you are using JTree? (I couldn't find a method named getIndex at all!)
As I couldn't quite understand what you are getting at, one thing that would be helpful is if you refer to "How to use Trees" in The Java Tutorial:
http://java.sun.com/docs/books/tutorial/uiswing/components/tree.html

How to get the index of the minimize point

Need to get the index of the minimize point, marked as red cycle in the attached word file.
It is a collected data from different sample devices, so the curve may change a bit each time. But the overall profile is the same, just 2 main peaks.
I tried to detect the Y difference to see when the difference values change from negative to positive.
But, there are noise as tiny peak when zoom in, shown in word file. Then tried to use median filter to make it smooth. (Maybe better method should be used.)
But there are still some bigger regional peak. Any suggestion?
Is there any labview function or better algorithm can make it. Many thanks for your help.

A trick I often use is to sample the data with a much higher speed than needed. Then I apply some simple averaging methods or and median filter. After that I downsample the signal to a adequate rate by averaging x samples. This have been a saver for me more than once. How successful it is depends of noise character type. It just a hint as it may not be applicable in your application

How to get the difference between two columns in a column group

Hi All,
My first time here and really new to programming. I would like to get the difference between 2 columns that are inside
a column group.
Here is my sample table below: The Column Group is PeriodNumber and can only choose 2. like 1 and 2.. I would like to have a third row which will simply calculate the difference between the amounts in PeriodNumber 1 and 2.
PeriodNumber
Account 1 2
1) Cash 10,000 15,000
2) Receivables 12,000 11,500
3) Equipment 5,000 5,500
Total Assets 27,000 32,000

Hi yabgestopa,
From your description, you want to get the difference between two columns in a column group. After testing it in my environment, we can use custom code to achieve your requirement. For more details, you can refer to the following steps:
Copy the custom code below and paste it to your report. (Right-click report>Report Properties>Code)
Dim Shared Num1 As Integer
Dim shared Num2 As Integer
Public Function GetAmount(Amount as Integer, Type as String)
If Type = "1" Then
Num1=Amount
Else
Num2=Amount
End If
Return Amount
End Function
Public Function GetDif()
Return Num1-Num2
End function
Right-click the second column to insert a third column with Outside Group-Right.
Then use the expressions below in the matrix.
=Code.GetAmount(Fields!Amount.Value,Fields!PeriodNumber.Value)
=code.GetAmount(Sum(Fields!Amount.Value),Fields!PeriodNumber.Value)
=Code.GetDif()
The report looks like below.
If you have any questions, please feel free to ask.
Thanks,

JSTL how to get the index of a ResultSet

in jsp can use like this
rs.getString(1);//rs is a ResultSet
and how to do this in JSTL?
<sql:query var="rs">
select count(*) from my
</sql:query>
${rs.rows[0].??????}

Look at the API for the classes used by JSTL: http://java.sun.com/products/jsp/jstl/1.1/docs/api/index.html
The jstl:query var object is of type javax.servlet.jsp.jstl.sql. Result
(see http://java.sun.com/products/jsp/jstl/1.1/docs/tlddocs/sql/query.html for details on the sql:query tag)
The rs has the following available to it:
rs.columNames (a String[])
rs.rowCount (and int)
rs.rows (an array of sorted maps)
rs.rowsByIndex (an Object[][])
rs.limitedByMaxRows (boolean)
The ones that might be helpful are:
rs.columnNames. As a String array, with one value per column, you try to get the count of objects in the array, or iterate through them when you are reading each row (maybe not the best idea)
rs.rows returns a SortedMap for each row. As a Map, it has the size() method which would tell you how many items. But it would also let you iterate through the map getting the values.
rs.rowsByIndes, as another means of counting the length of the columns via an array
Unfortunately, all of these means at getting to the value you want do not follow the JavaBeans specs, so you can't use simple JSTL or EL to get at them.
But once again, we could use the JSP function library to get at the data ( http://java.sun.com/products/jsp/jstl/1.1/docs/tlddocs/fn/tld-summary.html )
For instance, we might be able to do this:
<c:set var="colCount" value = "${fn:length(rs.rows[0])}"/> or
<c:set var="colCount" value="${fn:length(rs.columnNames)}" />
However, I have never tested this stuff (which is why I walked through the thought process here. If you follow along, and I made a mistake, you might be able to pick it up and fix it...)

How to get the value of multi-select in the Dashboard Prompt

I have a multi-select prompt in the Dashboard Prompt, what I want is, how do I know that user has choose one value,
for examle, for some reasons, if user didn't choose any value, then I will set one column in answer as "customer office" , if user choose one value, then the column in answer will be "customer name".
any comments, thanks.

Hi,
first define the presentation variable for the required column prompt. ex: PV
Then in report level set the filter for that column = @{PV}{customer office}. here u have to give default value as "customer office", so by default the report in dashboard will show customer office even though the user does not select any value from dashboard prompt.
Mark If Helpful/correct.
Thanks.
