IEssGridView.getData.getDataCellAttributes(int row, int column) returns 0
I am retrieving cells containing values. In trying to figure out whether the cell is a READ_WRITE or a READ_ONLY cell, I called the getDataCellAttributes method for the cells in question. They all return zero attribute values.I printed out the values of DATA_CELL_ATTRIB_READ_WRITE (2) and DATA_CELL_ATTRIB_READ_ONLY (1). Presumably a non-zero value should be returned by this call. What am I doing wrong?Nils
Try this:IEssDataCell dataCell = (EssDataCell)grid.getCell(i,j);if (dataCell.getAccessMode()==IEssDataCell.EEssAccessMode.READ_WRITE) {..} else {..}

JTable: Selecting rows in columns independently
Dear all,
I have a JTable with two columns. I want the user to be able to select cells in columns independently. At present, the entire row gets marked as selected. Is it possible at all to, for instance, select row1 1 to 3 in column 1 and rows 4 to 5 in column 2? If so, where's the switch? Thanks a lot in advance!
Cheers,
MartinAre you trying to use a seperate table for each column.
Thats not a good idear.
Here is what you have to do.
1. Create a sub class of JTable
2. You will have to redefine how the selection is done so. You will need some sort of a collection to store the list of selected cells indexes
2.1 Selecting a cell is simply adding the coordinations of the cell to the selection
2.2 de selecting is just removing it from the collection.
2.3 Here is what you have to override
setColumnSelectionInterval()
setColumnSelectionInterval()
changeSelection()
selectAll()
getSelectedColumns()
getSelectedColumn()
getSelectedRows()
getSelectedRow() You migh also need few new methods such as
setCellSelected(int row, int column, boolean selected);
boolean isCellSelected(int row, int column);
clearSelection();
int[][] getSelectedCells();You will have to implement the above in terms of your new data structure.
3. Handle mouse events.
Ex:- when user cicks on a cell if it is already selected it should be deselected (see 2.2)
other wise current selected should be cleared and the clicked cell should be selected
if your has pressed CTRL key while clicking the the cell should be selected without deselecting the old selection.
---you can use above using a MouseListener
When the user hold down a button and move the mouse accross multiple cell those need to be selected.
--- You will need a MouseMotionListener for this
You might also need to allow selection using key bord. You can do that using a KeyListener
4. Displaying the selection
You have to make sure only the selected cells are high lighted on the table.
You can do this using a simple trick.
(Just override getCellEditor(int row, int column) and getCellRenderer(int row, int column) )
Here is what you should do in getCellRenderer(int row, int column)
public TableCellRenderer getCellRenderer(int row, int column)
TableCellRenderer realRenderer = super.getCellRenderer(int row, int);
return new WrapperRenderer(realRenderer,selectedCellsCollection.isCellSelected(row,column));
static class WrapperRenderer implements TableCellRenderer{
TableCellRenderer realRenderer;
boolean selected;
public WrapperRenderer(TableCellRenderer realRenderer, boolean selected){
this.realRenderer = realRenderer;
this.selected = selected;
public Component getTableCellRendererComponent(JTable table,
Object value,
boolean isSelected,
boolean hasFocus,
int row,
int column){
return realRenderer.getTableCellRendererComponent(table,value,selected,hasFocus,row,column);
}What the above code does is it simply created wrapper for the Renderer and when generating the rendering component it replaces the isSeleted flag with our on selected flag
and the original renderer taken from the super class will do the rest.
You will have to do the same with the TableCellEditor.
By the way dont use above code as it is becouse the getCellRenderer method create a new instance of WrapperRenderer every time.
If the table has 10000 cells above will create 10000 instances. So you should refine above code.
5. Finnaly.
Every time the selection is changes you should make the table rerender the respective cells in or der to make the changes visible.
I'll leave that part for you to figure out.
A Final word
When implementing th above make sure that you do it in the java way of doing it.
For the collection of selected cells write following classes
TableCellSelectionModel // and interface which define what it does
DefaultTableCellSelectionModel //Your own implementation of above interface the table you create should use thisby default
//To communicate the selection changes
TableCellSelectionModelListener
TableCellSelectionModelEventif you read the javadoc about similer classes in ListSelectionModel you will get an idear
But dont make it as complex as ListSelectionModel try to keep the number of methods less than 5.
If you want to make it completly genaric you will have to resolve some issues such as handling changes to the table model.
Ex:- Rows and colums can be added and removed in the TableModle at the run time as a result the row and column indexes of some cells might change
and the TableCellSelectionModel should be updated with those changes.
Even though the todo list is quite long if you plan your implementation properly the code will not be that long.
And more importantly you will learn lots more by trying to implementing this.
Happy Coding :) -
A question about ResultSet.UpdateObject(int column, Object x)
hi, I write some code which use the TableModel to represent the data fetched from MS-ACCESS.
the problem is about the UpdateObject(...) method which is in the implement of the AbstractTableModel method setAtValue(). when transfered OBJECT TYPE is java.lang.String, I can't get the correct result in the JTable view.
my code is as below, could somebody point me out my problem
public class MyTableModel extends AbstractTableModel {

rs.updateObject(columnIndex+1, aValue);//the JTable column index is start from 0, so plus 1
rs.updateRow();
} catch (SQLException ex) {

}when the column type is about java.lang.String, the cell's result is incorrect, it looks like "[B@1f8f72f" and database can't update.It's me again.

Obiee 11g Administrator: Dividing an INT with an INT column results in INT
OBIEE 11.1.1.7.1
I have developed a formula column in BMM. The column is based on dividing an INT column with another INT column.
The formula column picks automatically the type as INT and when I developed a report on this column it shows integer values instead of decimal.
Dividing Profit by Cost (both integers) should give an index which is a decimal value. How to come up with that?Multiply with 1.0 to see decimal values
ex: (a*1.0)/b
or else try data format in report

Search row and column for return value
Dear Sir/Madam,
I have a problem for searching spreadsheet and hope you can help me out a bit. Im pretty new to Labview and Im currently using Labview 8.0. My task is to search the spreadsheet I have attached in row and column-wise, then return the corresponding value out. I had an attempt in doing this as you can see from the vi that i have attached. I try inputting the 'read from measurement file' into an array and using delete, index and search array I will be able to find the index value for the relevant row and column that i searched for by inputting them into an index array with the orginal array from the 'read from measurement file'.
So ultimately, when i enter a row value of 0.5 and a column value of 0.3, my output will be 1.688.
I can't see any mistakes in my logic but I getting really strange results, like I can read my data has been entered into an array but when i try deleting the first column and put it into another array, the orginal array with nothing deleted is outputted hence making my search to give out -1 value. So could you take a look please and give me any suggestion that can solve my problem or enhance the code a bit. Thank you for your time.
Best Regards,
Coato
P.s for some reason i can't attached the .lvm file of my data hence i have attached the excel version but i think you need to convert it back to .lvm for the 'read from measurement file' function to work.

Backswing compensation.csv 10 KB
Backswing comnpensation2.vi 109 KBYour VI makes absolutely no sense to me, but maybe I don't understand what you are trying to do.
You seem to have dynamic data with 6 signals and 48 points/channel. Now you reshape this into an array of dynamic data with 4x13 elements from which you slice out one row or column, resp. "delete from array" is NOT the correct tool to do this, use "Index array" with one index unwired to get a row or column as 1D array.
So you end up with two 1D arrays of dynamic data that you search for DBL. It is difficult to understand how you want to search for an array element that corresponds to a scalar DBL value of 0.1. Your array elements are NOT DBLs but dynamic data, each containing many signals!
There are two elements on all your data that are "3", the rest are zero. You will never find anything that is 0.1.
Maybe you can convert your original dynamic data to a 2D array with "rows are signals" using "convert from dynamic data", then operate on the 2D array.

Sorry, Please explain.
Please make a VI containing a simple 2D aray as diagram constant that contains e.g. 5x5 typical values. Let us know what kind of result you expect from your algorithm..

Hi Guys,
I have to add a new Big INT column to existing table in production, which holds 700 million records and would like to know the impact?
I have been tolled by one of my colleagues that last time they tried adding a column to same table during working hour and it locked out the table and impacted the users.
Please suggest/share If any one had similar experience.
Thanks Shiven:) If Answer is Helpful, Please VoteIf you add a new column to a table using an ALTER TABLE ADD command and specify that the new column allows NULLs and you do not define a default value, then it will take a table lock. However, once it gets the table lock, it will essentially run instantly
and then free the table lock. That will add this new column as the last column in the table, for example
ALTER MyTable ADD MyNewColumn bigint NULL;
But if you your change adds a new column with a default value, or you do something like using table designer to add the new column in the middle of the current list of columns, then SQL will have to rewrite the table. So it will get a table lock, rewrite
the whole table and then free the table lock. That will take a considerable amount of time and the table lock will be held for that whole period of time.
But, no matter how you make the change, if at all possible, I would not alter a table schema on a production database during working hours. Do it when nothing else is going on.

Can i search multiple sheets in a document for text in column a to return the entire row if column a matches in a
separate sheet?Thank you, Barry. That was helpful, and am hopeful that what I want to do is possible.
I am creating a spreadsheet that currently has 20 sheets, of which certain sheets have more than one table. I will be adding more sheets. I would like to return results for all occurences of the search string. Preferably into a seperate spreadsheet. It would be perfect if that seperate sheet updated whenever I update information in the first spreadsheet. To give an example:
Sheet: baskets
Tables: straw
wire
Sheet: barware
Tables: glasses
decanters
coasters
My tables all have the same titiels:
Vendor Description Cost Selling Price
Since I will have upwards of 100 sheets, with multiple tables, and most of my vendors will fit into multiple sheet categories, it would be helpful if I could also see what my order will be from each vendor, not just who I will be ordering each item from. How would I do that?
I hope I conveyed that properly.
Thank you in advance for your help,

I think you intended your question for the other DV community here: https://supportforums.cisco.com/community/12298251/cisco-data-virtualization
Although our parser allows the syntax of these analytic functions such as ROW_NUMBER to be submitted to us from a client, our query engine is not capable of processing it locally.
It is up to the user to ensure the resulting query plan will push the sql containing that function down to the external db (ie; oracle) to be processed there instead. Creating the query from inside a view will provide the ability to see the resulting query plan.
Which customer (company) are you with? If you need further assistance, I recommend you log a support case with Cisco.
Thank you,

JTable about selection mode, setting a Color to rows and column.
I need an application with a table containing Double and String data. When the table is shown the Double data must be shown as selected. I need a special kind of selection mode similar to MULTIPLE_INTERVAL_SELECTION but it must be a mode as if CONTROL was pressed when the user left clicks the table so he or she can select and deselect columns without deselecting those wich have been selected previously... Besides I need to paint columns and rows only if they have certain conditions. This is an example of what I have done so far... The selection mode is what is really important.

}Interesting concept! This is what I have tried and it works, but in the application I need the user to deselect the columns he wants only by left clicking on them... This is the main idea: there will be lots of columns (String and Double data). The user must deselect the Double columns he or she does not want to be processed... Maybe with a boolean array that changes it state if a user left clicks a column... but I suppose this method is called only once to initialize the table, isn't it? Thanks.

Hi
Could anyone tip me how to make fixed row and column in the same table(s).
I know how to make column fixed and row, tried to combine them but it didnt look pretty.
Can anyone give me a tip?
Thanks! :)Got it to work!

How do I select the end of a row or column in Numbers?
I am trying to select to the end of a column in Numbers. In Excel, I simply hold down the shift+command+arrow keys and I can select the entire row or column int he arrow direction. How do I do this in Numbers?
Here two other scripts :
Select-to-top and select-to-left.
Both of them take care of possible headers.
--{code}
--[SCRIPT select-to-top]
Enregistrer le script en tant que Script : select-to-top.scpt
déplacer le fichier ainsi créé dans le dossier
<VolumeDeDémarrage>:Utilisateurs:<votreCompte>:Bibliothèque:Scripts:Applications :Numbers:
Il vous faudra peut-être créer le dossier Numbers et peut-être même le dossier Applications.
Sélectionner une ou plusieurs cellules d'une ligne dans une table de Numbers
Aller au menu Scripts , choisir Numbers puis choisir “select-to-top”
Il étendra la sélection jusqu'à la première ligne standard de la colonne (ne sélectionne pas les rangs d’en tête).
Bien entendu, ce script sera plus intéressant si vous le dotez d'un raccourci clavier à l’aide, par exemple, de FastScripts.

L’Utilitaire AppleScript permet d’activer le Menu des scripts :
Ouvrez l’Utilitaire AppleScript situé dans le dossier Applications/AppleScript.
Cochez la case “Afficher le menu des scripts dans la barre de menus”.
Sous 10.6.x,
aller dans le panneau “Général” du dialogue Préférences de l’Éditeur Applescript
puis cocher la case “Afficher le menu des scripts dans la barre des menus”.

Save the script as a Script: select-to-top.scpt
Move the newly created file into the folder:
<startup Volume>:Users:<yourAccount>:Library:Scripts:Applications:Numbers:
Maybe you would have to create the folder Numbers and even the folder Applications by yourself.
Select one or several cells in a row of a Numbers table.
Go to the Scripts Menu, choose Numbers, then choose “select-to-top”
It will expand the selection to the first standard row of the table (minus header rows).
Of course, it would be more useful if you attach a shortcut thanks to a tool like FastScripts.

}Here I would guess your problem is with
public Object getValueAt(int rowIndex, int columnIndex) {
return (String)data.elementAt( (rowIndex * getColumnCount()) + columnIndex);
}Even though you only have seven items in your data Vector, the table will
still try to populate all the cells in the number of rows you have. So, you
need to check if the index is greater than the Vector size and return an
empty string in that case. Something like
public Object getValueAt(int rowIndex, int columnIndex) {
int index = rowIndex * getColumnCount() + columnIndex;
return index < data.size() ? data.elementAt( index ) : "";

Summing the Rows and Columns in an Array
I am importing a 2-dimensional array of integers.(which is held in a 2-dimensional array)
I need to store the row sums and column sums in separate 1-dimensional arrays.
I can get the integers in and print out a list along with the grand total(sum of all).
But, how do I pass each row's and each column's value in to my sumRow and sumCol methods to get the sum for each row and each column?
Can I do the row and column summing in the same "for" statement where I calculate the "grand total"? Or am I making this more difficult than it is?
Would appreciate any help.
This is what I have so far:
import java.awt.Graphics;
import java.applet.Applet;
public class TwoWayTable extends Applet {
int numRows;
int numCols;
int [] [] cell;
int [] rowSum;
int [] colSum;
int grandTotal;
public TwoWayTable(int [][] data){
grandTotal = 0;
cell = new int [data.length][data.length];
for(int i = 0; i < data.length; i++)
for(int j = 0; j < data.length; j++){
cell[i][j] = data[i][j];
grandTotal += cell[i][j];
System.out.println(cell[i][j]);
System.out.println(grandTotal);
public int sumRow(int [] data2){
int rowaccumulator=0;
rowSum = new int[data2.length];
for(int numRows = 0; numRows < rowSum.length; numRows++){
rowaccumulator += rowaccumulator + rowSum[numRows];
return(rowaccumulator);
public int sumCol(int [] data3){
int colaccumulator = 0;
colSum = new int[data3.length];
for(int numCols = 0; numCols < colSum.length; numCols++){
colaccumulator += colaccumulator + colSum[numCols];
return(colaccumulator);Thanks for your input.
I'll make the changes that you suggest.(after this)
My output prints:
4 6 3 8 21
9 1 5 3 18
13 7 8 11 39
numbers are right, but I need to format the table
the output needs to look like this:
int int int int | rowsum
int int int int | rowsum
colsum colsum colsum colsum | total
How do I do this?
I have no idea?
I'm supposed to call a "void setMargins( )" method to line this up, without
using the exotic formatting in the IO library.
I'm also supposed to use "public String toString( )"
This is what I have so far:
import java.awt.Graphics;
import java.applet.Applet;
public class TwoWayTable extends Applet {
int numRows;
int numCols;
int [] [] cell;
int [] rowSum;
int [] colSum;
int grandTotal;
public TwoWayTable(int [][] data){
cell = new int [data.length][data.length];
for(int i = 0; i < data.length; i++){
for(int j = 0; j < data.length; j++){
cell[i][j] = data[i][j];
calcTotals(cell);
for(int i = 0; i < cell.length; ++i){
for(int j = 0; j < cell.length; ++j){
System.out.print(cell[i][j] + " ");
System.out.println(rowSum[i] + " ");
for(int j = 0; j < cell.length-1; ++j){
System.out.print(colSum[j] + " ");
System.out.println(colSum[cell.length-1] + " " + (grandTotal));
public void calcTotals(int [][] data2){
grandTotal = 0;
rowSum = new int[data2.length];
colSum = new int[data2.length];
for(int numRows = 0; numRows < data2.length; numRows++){
for(int numCols = 0; numCols < data2.length; numCols++){
grandTotal += data2[numRows][numCols];
rowSum[numRows] += data2[numRows][numCols];
colSum[numCols] += data2[numRows][numCols]; -
Hi,

==================================
however when I run the bulk load utility I get the error
=======================================
Bulk load data conversion error (type mismatch or invalid character for the specified codepage) for row 1, column 3 (NumberOfMultipleMatches).

the bulk insert statement is as follows
=========================================
BULK INSERT Temp
FROM '<file name>' WITH
FIELDTERMINATOR = ','
, KEEPNULLS
==========================================
Does anybody know what is happening and what needs to be done ?
PLEASE HELP
Thanks in advance
VikramTo load that file with BULK INSERT, use this format file:
9.0
4
1 SQLCHAR 0 0 "\"" 0 "" ""
2 SQLCHAR 0 0 "\",\"" 1 col1 Latin1_General_CI_AS
3 SQLCHAR 0 0 "\",\"" 2 col2 Latin1_General_CI_AS
4 SQLCHAR 0 0 "\"\r\n" 3 col3 Latin1_General_CI_AS
Note that the format file defines four fields while the fileonly seems to have three. The format file defines an empty field before the first quote.
Or, since you already have a .NET program, use a stored procedure with table-valued parameter instead. I have an example of how to do this here:

JTable Problem (table does not show rows and columns)
Hi All,
What the table is suppose to do.
- Load information from a database
- put all the values in the first column
- in the second column put combobox (cell editor with numbers 1-12)
- the 3rd column put another combobox for something else
- the 4th column uses checkbox as an edit
The number of rows of the table should be equal to the number of
record from
the database. If not given it default to 20 (poor but ok for this)
The number of columns is 4.
But the table does not show any rows or
column when I put it inside a
JScrollPane (Otherwise it works).
Please help,
thanks in advance.

----------------------------END TABLE MODEL----------------------------------I hope you don't expect us to read hundreds of lines of unformatted code? Use the "formatting tags" when you post.
Why are you creating your own TableModel? It looks to me like the DefaultTableModel will store you data. Learn how to use JTable with its DefaultTableModel first. Then if you determine that DefaultTableModel doesn't provide the required functionality you can write your own model.
