Is there a OracleDataReader hasNext() method?
Hi all!
How can I see if I have a register to read without moving the cursor?
OracleDataReader o = ...;
Instead of doing "o.Read()" do something like "o.hasNext()"?
Is there a way to do this?
Best Regards,
Are you looking for o.HasRows to check whether the reader has one or more rows, instead of doing "o.Read()"?
ODP.NET 10.1.0.3 OracleDataReader has the property.

My iPad camera photos will wirelessly sync with my iMac and iCLoud photo stream, but the videos do not, is USB connection the only way to transfer videos or is there also a wireless method?
Videos are not included with the Photo Stream. Photo Stream is for photos only.
There is not a wireless method for importing videos from the iPad's Camera Roll. -
I want to change my account payment method to none and I do not have a credit card yet.Plus, iTunes gave a message saying that I need to review my account and when I go there,the none payment method is hidden.
Assuming that you want help and that you aren't just copying-and-pasting that thread's title and posting a link to it, then have you tried the steps on the post that I linked to in my first reply on that thread ?
If you don't get the 'none' option when trying those instructions then you will need to enter credit card details before you will be able to use the account - when you've entered credit card details you should get the 'none' option and be able to remove your card details.
Or you can create a new account, and follow, exactly, the steps on this page when creating it' : http://support.apple.com/kb/HT2534 -

There are two CDC methods - Source based CDC and Target based CDC, which one is better performancewise. in data services.
If there is any document available which compares both and provides any info on performance etc, will be helpful.
thank you for the helpful info.LIke Suneer mentioned CDC is for better performance.
Following link would be helpful.

Was there a change in method names for ABAP Proxies ???
Hi all,
i am wondering if there was a change in the method names when using ABAP proxies.
In my projects there were always the methods execute_synchronous and execute_asynchronous when generating proxies.
In a current project i created some ABAP proxies and the method names are not the same any longer. Now the method takes the name of the Message interface. I observed this in Backendsystems NW2004s (Basis 7.0) with SP14 and 15. It seems that it has changed since the sproxy was integrated in SE80.
Can anybody tell me, how i can use the "old" method names again when generating proxies ?
Best regards,
martinActually i guess they did in more SOA way. If u see it says connecting to ESR rather than integration repository.
Yes. In order to allow several operations for a message interface, the methods of the ABAP proxies get the operation name as method instead of a constant (the Java proxies alwas had this behaviour).
could u pl highlight what other operations are allowed on message interface rather than sending a message to the XI either in synchronous or asynchronous manner?
Thanks and Regards

Why there are overloaded create methods in Statful bean?
Hi all,
I have a question ...!
Why there are overloaded create methods for Statefule beans? and why not for Stateless bean?
because any way these create methods are for giving referneces of EJB objects.hence, what is use of overloaded methods in stateful bean?
Thanks in advance.
Regards,
RahulHi Rahul,
Each stateful session bean is tied to a particular client. That means whatever state is passed in during create() is guaranteed
to be available on subsequent invocations. Allowing multiple create methods is a convenience.
For stateless session beans there is no prescribed relationship between the caller and which bean instance is used to handle
an invocation. It wouldn't make sense to allow creation parameters since there would be no guarantee that a subsequent
invocation is handled by an instance containing that particular initialization state.
All of this only applies to the EJB 2.1 and earlier API. Starting in EJB 3.0, there are no longer explicit create() methods.
As you've seen there isn't any benefit to having them in the stateless case. For stateful session beans in EJB 3.0, the
developer can perform initialization by just declaring a particular business method and calling that after first acquiring a
new stateful session bean reference.

If there are two synchronized methods in one class.
If there are two synchronized methods in one class then what will be the beheviour of the threads accessing the methods.
Synchronization is on objects, not methods or classes. A thread, entering a synchronized method, synchronizes on the object on which that method is called. Another thread, attempting to synchronize on that object, will be made to wait until the first thread releases it.

IS THERE ANY FUNCTION OR METHOD TO KNOW CURRENT OPERATIN SYS
Hi,
is there any function or method to know current operating system where peoplecode is runnig or any system variable
thanks,
AmitCTRL + J displays the operating system.
In terms of the code that does this, as discussed in this article:
http://www.peoplesoftwiki.com/limit-control-j-information
You can look at the PT_INFOPAGECONNECT HTML definition which uses the system variable %BrowserPlatform to show this information.
According to PeopleBooks, this system variable resolves to:
At runtime %BrowserPlatform is replaced with the operating system name as specified by the browser loading the current page. -
Adding a JButton when there's a paint method
I'm creating a game application, sort of like a maze, and I want to add buttons to the levelOne panel to be able to move around the maze. When I add the buttons to the panel they don't appear, I assume the paint method is the reason for this. here's my code, I have 3 files, ill post the user_interface, and the levels class, where the level is created and where i tried to add the button. I tried putting the buttons in a JOptionPane, but then my JMenu wouldn't work at the same time the OptionPane was opened. If anyone knows a way around this instead, please let me know. I also tried using a separate class with a paintComponent method in it, and then adding the button (saw on a forum, not sure if it was this one), but that didn't work either. Also, if there is a way just to simply have the user press the directional keys on the keyboard and have the program perform a certain function when certain keys are pressed, I'd like to know, as that would solve my whole problem. Thanks.

}i tried adding a keylistener, that didn't work too well, i had tried to add it to a button and a textarea which i added to the 'one' frame, it didn't show up, and it didn't work. How would i go about changing the paint method so that it doesn't contain any logic? That's the only way I could think of getting the program to move forward in the game. Thanks.

Why there are two init methods?
I copied this code from netbeans for a JApplet.. and it has two init methods
One is public void init() that calls another initComponents() method.
And the initComponents() method has all the components defined in it, and it is private.
I replaced private with public and changed initComponents to init, and then deleted all the init method, it worked that way.
But why there two methods when you can put every thing in single init() method?
The init() method has this code in it:
public void init() {
try {
java.awt.EventQueue.invokeAndWait(new Runnable() {
public void run() {
initComponents();
} catch (Exception ex) {
ex.printStackTrace();
}BDLH:
WWJD? Probably code in Ruby, but I digress. No, he would define an abstract base for that boilerplate code:
import java.awt.*;
import java.lang.reflect.*;
import javax.swing.*;
public abstract class AbstractApplet extends JApplet {
public void init() {
try {
EventQueue.invokeAndWait(new Runnable() {
public void run() {
initComponents();
} catch (InterruptedException ex) {
ex.printStackTrace();
} catch (InvocationTargetException ex) {
ex.printStackTrace();
protected abstract void initComponents();
//ditto: start, stop, distroy

Is there a default focus Method ?
I would like to have a button to be focused by default within a dialog such that user can easily fire the button's action. Is there a method to set default focus on a button ? Thanks !!!
That's actually very helpful. I can now set a default focus button on a dialog. But then for some reason I can not set it for other dialogs initiated by this dialog. Since I have an opening dialog with a number of buttons, and those buttons will open up a new dialog. Right now I can only set the default focus to the opening dialog. The other dialogs that opens up from firing the buttons did not have the same effect as the opening dialog. Is there a way to fix it ? Thanks

Is there anyone using Java Methods interface of IREP in his application
Hello everyone,
Are you using Java Methods interface of IREP in your application?
Nowadays I am trying to using Java Methods in my application. But I'm puzzled how to get the interface jar files that the Java Methods would import. It seems that Oracle doesn't provide such interface jar files for all Java Methods shipped in IREP. How do you do with this?
If you have some experience about using Java Methods in application, hope to hear your voice. Thanks in advance.Hi friend,
Thanks for you update.
I'm referring to Java Methods that can be called directly by applications not Java Service Interface. These are two different kinds of IREP interfaces. In Oracle Integration Repository User's Guide, there aren't much guidance about how to use Java Methods.
I appreciate you can help me further.
