Getdate - yyyymmdd returining int in derived coloumn

In table, if the column is having 20140810 [ date in yyyymmdd format ]
Result to be 11 returning in the expression using derived
destination value is the [columndate] - getdate
================
Source Table Column [Valyyyymmdd] [nvarchar](24) NULL
Destination Table Column
[DestColumn] [int] NULL,
=================
20130503
20120403
00000000
20110523
20100715
I want to get the difference with getdate()
so i used the below SQL query in my source
DATEDIFF(DAY, IIF( [Valyyyymmdd] ='00000000', CONVERT(VARCHAR(8), GETDATE(), 112), [Valyyyymmdd]) , getdate()) as SalesStageAging
but i need to get the Valyyyymmdd and do ssis derived column to get the difference in date resulting in int value.
I tryed as below
((DT_WSTR,24)DestColumn == "00000000" ? GETDATE() : (DT_DBDATE)(SUBSTRING((DT_WSTR,10)DestColumn,1,4) + "-" + SUBSTRING((DT_WSTR,10)DestColumn,5,2) + "-" + SUBSTRING((DT_WSTR,10)DestColumn,7,2)))

Are you trying to get the datedifference for those integer date format against getdate() and store the integer day value in the destination table ? If it is correct i have a recomendation to filter your integer date format by length, if possible by date
validity as well. For this use SQL command in OLEDB source i.e select Valyyyymmdd from sourceTable where len(Valyyyymmdd) = 8.
And use the below expression in the derived column transformation,
Valyyyymmdd == "00000000" ? 0 : DATEDIFF("d",(DT_DATE)(SUBSTRING(Valyyyymmdd,5,2) + "/" + SUBSTRING(Valyyyymmdd,7,2) + "/" + SUBSTRING(Valyyyymmdd,1,4)),GETDATE())

Accessing private field of Derived object in Base class

Hi,
I have this piece of code I wrote a while ago to test something. The issue is accessing a private field of Base class in Base but of a Derived object.
Here is the code:
class Base
     private int x;
     public int getX()
          return x;
     public int getX(Derived d)
          // return d.x;
          return ((Base) d).x;
}The commented code does not work but casting d to Base does.
Can someone please explain the reasoning for this.
Forgot to mention that the compilation error is that x has private access in Base.
Thank you.

>
As I understand the explanation says that you can access any private member within the code of the class that encloses the private member. So in this case x is the private member and the line of code (return d.x) is in Base which encloses the private member. Does it have to do with the fact that the Derived class does not in fact inherit the private members of Base?
>
It has to do with the entire quote from the spec
>
A private class member or constructor is accessible only within the body of the top level class (§7.6) that encloses the declaration of the member or constructor. It is not inherited by subclasses
>
Your code is
public int getX(Derived d)
          // return d.x;
          return ((Base) d).x;
     }The 'Derived' class is NOT 'the top level class that encloses the declaration of the member'. It does NOT inherit 'x' which is a private member of 'Base'. As far as the 'Derived' class is concerned 'x' does not exist.
>
If outside Base code I have Derived d = new Derived() and I call d.getX() then isn't that like calling d.x in myX()?

How is that the same? 'Base' owns 'x' and can do whatever it wants with it. 'Derived' has no knowledge of 'x' and CAN NOT access it.

How to Convert array of int into array of byte - please help

I have a 2-dim array of type int and I want to convert it to an array
of byte. How can I do that? Also, if my 2-dim int array is one dimention
can I use typecast as in the example below?
private byte[] getData()
byte []buff;
int []data = new int[5];
//populate data[]
buff = (byte[]) data; <---- CAN I DO THIS??????
return buff;

hi, I suggest you make an array of byte arrays
--> Byte[][] and use one row for each number
you can do 2 things,
take each cipher of one number and put one by one in each column of the row correspondent to that number. of course it may take too much room if the int[] is too big, but that is the easiest way I think
the other way is dividing your number into bitsets(class BitSet) with sizes of 8 bits and then you can save each bit into each column of your array. and you still have one number in each row. To put your numbers back use the same class.
Maybe someone has an easier way, I couldnt think of any.

Casting string as int always makes it zero?

Hi
I've had to make
_myID = event.selectedRow.getData("my_id");
into
_myID= event.selectedRow.getData("my_id") as int;
so that it stops causing a warning when my buddy loads it into FlashDevelop (I'm working in Pro)
Since then, every myID becomes 0. eg if event.selectedRow.getData("request_id") contains "29" it turns 29 into into zero.
What should I do so that "29" becomes 29?
Thanks for taking a look.

You can also use parseInt and parseFloat, which have the advantage of letting you check for isNaN if the cast fails (but the variable type needs to be Number for this to work--I don't think int can be NaN).

}

It may be that the code in getString() returns a
String that ends with a newline. If that is the
problem, you can use
return (Integer.parseInt(st)).trim();1. getString will never return a String ending in newline. BufferedReader.readLine strips off the newline.
2. Even if you had a newline, String.trim doesn't trim newlines.
3. You would need to trim the String, not the int:
return (Integer.parseInt(st.trim()));As JimDinosaur said, you are passing bad data (the value of "st").
In getInt, add this before trying to parse "st":
System.out.println("###"+st+"###");What does it print?

your help appreciated.

lotto[0] = new Ticket1(0001,02121982, 03, 11, 12, 14, 41, 43, 13);
You can't do that. The second parameter for the constructor is Date, >not int. You have to pass a Date Object. ...02122982 is the date in my data file,i thot bcz i identified that field in my Ticket constructor it would know that i wanted 02122982 to be interpreted as a date....
...brain is toast.
i tried to create
public Date getDate(){ return date }//but i commented this out bcz
no matter how i tried it still gave me errors...
or is it
public Date getDate(){ return this.date }//
or is it
in TestGame
drawDay = new Date(Date xxx);
so your saying i can keep 02122982 as an arguement
& that the constructors parameter is expecting an object... how do i make it look like an object?

Can't get my class's getter method to work properly.

Hello, I am new to Java programming, although I come from C and C++. This is my first post. I am working on a basic Library application that can Checkout and Return books. Eventually I would like to add the ability to read from and write to an XML file containing data for every book.
My problem right now is that I cannot get my getter method within my Book class to work properly. When I call getData() from within main, and pass the appropriate arguments, instead of filling the variables with that object's data, it leaves them blank! Please help me.
Here is my method within the Book class, the person and id_num are private.
/* Gets general Book Instance Data and fills parameters with it */
     public void getData(String n, int num, String c, String d)
          n = this.person;
          num = this.id_num;
          c = this.checkout_date_string;
          d = this.due_date_string;
     }Here is how I am attempting to use it in main:
String name = "";
int number = 0;
String checkout = "";
String due = "";
Book book1;
/*Sets person = John Smith and id_num = 10763*/
book1 = new Book("John Smith", 10763);
/*Gets Checkout (todays) date and sets a due date in 2 weeks*/
book1.Checkout();
book1.getData(name, number, checkout, due);
System.out.println("Book1:\n Checkout Date: " + checkout +
                         "\n Due Date: " + due + "\n Is it late: " + book1.isLate() +
                         "\n Person who checked it out: " + name + "\n ID number: " + number +
                         "\n ");Then, Here is the Output:
Book1:
Checkout Date:
Due Date:
Is it late: false
Person who checked it out:
ID number: 0

Well I went ahead and made separate methods to return each value. I suppose that will work just as well, especially since now I don't have to declare a bunch of strings and int's to hold the data and pass to the method.
>
Well this would never work anyway
public void getData(String n, int num, String c, String d)None of those can be changed within the method. Strings are immutable and 'int' is passed by value. Each of those parameters will have the same value after the method exits as they did before it was called.
Your book class should be using 'setters' to set the value of its instance variables.

          ByteArrayOutputStream pdfSourceOutputStream = new ByteArrayOutputStream();
          try {
               InputStream pdfSourceInputStream = wdContext.currentContextElement().getData().read(false);
               BufferedInputStream bufferedInputStream = new BufferedInputStream(wdContext.currentContextElement().getData().read(false));
               int aByte;
               while ((aByte = bufferedInputStream.read()) != -1) {
                    pdfSourceOutputStream.write(aByte);
               pdfSourceOutputStream.flush();
               pdfSourceOutputStream.close();
               IWDPDFDocument pdfDocument = null;

NT security problems with file I/O

I have 2 problems with file I/O. When I read from a file I use the getAbsolutePath() method that is part of the File class to find what directory the files are currenlty. The problem is that the returned path says that the file is on the desktop no matter what directory the file really is in. The second problem is that I am unable to save files anywhere but the desktop. I must run the class files from the desktop too to get it to work.
I am using NT 4.0 for development. I'm guessing that these problems might be NT security related. Could someone help me?

Cannot use multiple database in my application

I have written a C++/CLI wrapper for use berkeleydb without lost performance. This wrapper run perfectly with one database but when i open a second database ( i create a new instance of the wrapper ) the application crash.
I have written a minimal pure C++ application that use the pure C++ classe of my wrapper, when a open and use only one database the code run perfectly but with two databases, the application be crazy.

/ ====
The application output show that when using two database the data is not correctly set. It seems that db and db1 is the same object :|.
For example in db i insert a key => toto with value 4, and in db1 i insert the same value nomaly have no problem. But berkeleydb say the the key toto in db1 already exist while not
I don't understand.
NB : sorry for my english

As a side note, it is unlikely that you want both
DB_READ_UNCOMMITTED and DB_MULTIVERSION to be set.
This combination pays a price during updates for
maintaining multiple versions, but still requires
(short term) locks to be held during reads. The BDB/XML Transaction Processing Guide states the following:
[...]in addition to BDB XML's normal degrees of isolation, you can also use snapshot isolation. This allows you to avoid the read locks that serializable isolation requires.
http://www.oracle.com/technology/documentation/berkeley-db/xml/gsg_xml_txn/cxx/isolation.html
This seems to contradict what you're saying here.
Is there a general guideline on whether or not to use MVCC together with a relaxed isolation degree like DB_READ_UNCOMMITTED? Should the statement in the BDB/XML TP Guide rather have "as an alternative to" instead of "in addition to"?

Double click on a JTable row.

I got and run a sample about double click on a JTable and it works fine. This sample defines a TableModel as shown at the end this note.
On the other hand, I have an application in which I have defined a JTable
using the DefaultTableModel as follows :
DefaultTableModel dtm = new DefaultTableModel(data, names);
JTable table = new JTable(dtm); where data and names are String arrays.
Of course the mouse listener stuffs have been also specified.
table.addMouseListener(new MouseAdapter(){
     public void mouseClicked(MouseEvent e){
      if (e.getClickCount() == 2){
         System.out.println(" double click" );
     } );Because the difference with the sample was the table model,
I changed it with the DefaultTableModel class. At this point, the Double click does not work anymore.
So I gues it should be an option which prevents double click to work.
I thought of using mousePress() instead of mouseClick(), but it's very dangerous (I tried). . If by error the user clicks twice (instead of only once) the mousePress method is invoked twice for the same entry
My question is now simple, may I use double click on a JTable with the default table model. If so, what I have to do ?
Thanks a lot

Converting japanese characters to UTF-8

Hi
I am working on a internationalized application where we display the content from Property based Resourc Bundle. The resource bundle is in Unicode format and we use UTF-8 charset in our JSP files to display it. Till this point its working perfectly. But in our application on some JSP pages we also get data from third party Components as well. For example in on of the JSP pages we get a ArrayList of some values that we need to display on the JSP page. But the problem is that this list of values is not in Unicode format. We need to convert the values in the ArrayList to their String representations that are UTF-8 compatible. We have tried a lot many number of ways but have not been able to do so. Please specify as to what should be done.

hi,
if your data is in unicode format then there is no issue of storing the value in ArrayList or anything.
please check the following things,
1.if you r getting calue from database and store it in ArrayList..please check wheather the database is unicode supporting.
with regards,
kss.
(this is the sample code,
<%@ page contentType="text/html;charset=UTF-8" %>
<%@ page import="java.util.Hashtable" %>
<%@ page import="rnd.DbConnection" %>
<%@ page import="java.sql.*" %>
<html>

          ResultSet rs = stmt.executeQuery(query);
          int row = 1,coloumn = 1;
          while(rs.next()) {
               coloumn = 1;
               h.put(row + "table" + coloumn,rs.getString("name"));
               coloumn++;
               h.put(row + "table" + coloumn,rs.getString("password"));
               count = count + 1;
               row++;

JTable -showing column headers and displaying multi-line strings

Hi,
This is two questions really.
#1 - Does anyone know why my column headers aren't showing in my jtable using the model below?
#2 - Does anyone know how I can display, mulitple line strings in a jtable? Currently my newline character ('\n') is just being displayed as a character.
any help very much appreciated,
Tom
private class TaskHistoryTableModel extends AbstractTableModel {
private List taskHistory = new ArrayList();
public Object getValueAt(int row, int col) {
if (col == 0) {
return ((TaskHistoryItem) taskHistory.get(row)).getText();
} else {
return ((TaskHistoryItem) taskHistory.get(row)).getDate().getTime();
public int getRowCount() {
return taskHistory == null ? 0 : taskHistory.size();
public int getColumnCount() {
return 2;
/** Getter for property taskHistory.
* @return Value of property taskHistory.
public List getTaskHistory() {
return taskHistory;
/** Setter for property taskHistory.
* @param taskHistory New value of property taskHistory.
public void setTaskHistory(List taskHistory) {
this.taskHistory = taskHistory;
public String getColumnName (int col) {
return col == 0 ? "Text" : "Entered At";
public boolean isCellEditable(int row, int col) {
return false;
}

fixed my own problem - make your mulit-line string into html format e.g.
this string will appear on two lines in a jtable
"<html><p>A much more interesting entry</p> <p>on multiple lines</p></html>"
