Getting the instance of a program

I'm trying to build an app that when starting checks if there's another instance of the same program running, and get an instance to the other program. Basically i'm trying to avoid having 2 application windows, and reuse the existing window when the program is called again.
Is there a standardized method for doing so? if not, does anyone have some sample code ?

Getting the Instance of a Class

I have this program where each user had there own prefences stored in there directory. A class called UserPrefences load the prefences into the data members of that class.
The problem is I want to get the instance of that prefences which was loaded to be accessed by other classes. I don't want to have to reload all the prefences again from a text file but rather get the instance of UserPrefences from different class. So how do I get the instance of that one class without creating a new object each time I access prefences from a different class?

Singleton????It's a design pattern you use when you want exactly one instance of something to exist.
Can there be a static class? Top level classes cannot be static, but you can have a class full of static member variables.
Because there are many
fields in these prefences.Not sure how that's relevant.
You've given almost no information about your requirements, so I can't really give you any more specific help.

Get the instance names of clips attached to a movieclip

I want to get the instance names of all the cmovieclips that
are attached to a movieclip.
Is there a simple way to do this.
I imagine this is something that can be done with AS3 but can
it be done with AS2?
regards J

you're welcome.
FYI: a for...in loop loops through all the accesible
properties (in the broadest sense of the meaning, includes
methods/functions and variables etc). Each time it finds one it (in
this case) assigns the property name to the variable 'unknown'
the code inside the loop just checks
a) is it a property that references a movieclip instance and
b) is it the same property name as the movieclip instance's
_name property (this is to avoid listing additional references to
the same movieclip instance that may be set up as variables in your
McA's scope).
I just read that and I'm wondering if it actually will help
you understand... its quite complicated to describe,sorry...
although its simple to understand once you get used to it. To learn
you should experiment with a few for.. in loops on different
objects and see what trace outputs you get.

How do I get the instance of a serviceticket in ICCMP_BTPARTNER?!

Hi all,
I want to find out which instance/ibase is currently set in a serviceticket. I am in the component "ICCMP_BTPARTNER" in the view "PARTNERTABLE".
I thought I might get the instance of the serviceticket in the global data context in GDC_CURRENTIBASE or GDC_CURRENTSERVICETICKET. But the CURRENTIBASE is initial and in SERVICETICKET the only information I get is the CRM_GUID.
I tried something like this...
CLEAR: lr_gdc.
TRY.
      lr_gdc ?= cl_crm_ui_data_context_srv=>get_instance( iv_controller = me ).
    CATCH cx_root.
ENDTRY.
CHECK lr_gdc IS BOUND.
CALL METHOD lr_gdc->get_entity
    EXPORTING
      name = if_iccmp_global_data_cont_con=>gdc_currentibase
    RECEIVING
      value = lr_serviceticket.
CHECK lr_ibase IS BOUND.
So, does anyone know how to get the current instance of a serviceticket in any other components view (here ICCMP_BTPARTNER/PartnerTable)?
Thanks for your help.
Best regards.
Ben

How to get the output of a program into the email program.

hi
i had created a java mail program and the keygeneration program.seperately.
i want to get the keygeneration into my email program.that should be sent along with the text message.so pls help me in this regared.
i had pasted my coding her
email pgm.
import javax.mail.*;
import javax.mail.internet.*;
import java.util.*;
import java.io.*;
To use this program, change values for the following three constants,
SMTP_HOST_NAME -- Has your SMTP Host Name
SMTP_AUTH_USER -- Has your SMTP Authentication UserName
SMTP_AUTH_PWD -- Has your SMTP Authentication Password
Next change values for fields
emailMsgTxt -- Message Text for the Email
emailSubjectTxt -- Subject for email
emailFromAddress -- Email Address whose name will appears as "from" address
Next change value for "emailList".
This String array has List of all Email Addresses to Email Email needs to be sent to.
Next to run the program, execute it as follows,
SendMailUsingAuthentication authProg = new SendMailUsingAuthentication();
public class SendMailUsingAuthentication
private static final String SMTP_HOST_NAME = "smtp.mail.yahoo.com";
private static final String SMTP_AUTH_USER = "xxxx";
private static final String SMTP_AUTH_PWD = "xxxx";
//private static final String emailMsgTxt = "Online Order Confirmation Message. Also include the Tracking Number.";
private static final String emailSubjectTxt = "Order Confirmation Subject";
private static final String emailFromAddress = "[email protected]";
private static String emailMsgTxt = "I am unable to attend to your message, as I am busy sunning"
+ "myself on the beach in Maui, where it is warm and peaceful."
+ "Perhaps when I return I'll get around to reading your mail."
+ "Or perhaps not.";
private static final String[] emailList = { "[email protected]","[email protected]"};
public static void main(String args[]) throws Exception
SendMailUsingAuthentication smtpMailSender = new SendMailUsingAuthentication();
smtpMailSender.postMail( emailList, emailSubjectTxt, emailMsgTxt, emailFromAddress);
System.out.println("Sucessfully Sent mail to All Users");
public void postMail( String recipients[ ], String subject,
String message , String from) throws MessagingException
boolean debug = true;
Properties props = new Properties();
props.put("mail.smtp.host", SMTP_HOST_NAME);
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "25");
props.put("mail.smtp.protocol","smtp");
props.put("mail.debug", "true");
Authenticator auth = new SMTPAuthenticator();
Session session = Session.getDefaultInstance(props, auth);
session.setDebug(debug);
// create a message
Message msg = new MimeMessage(session);
// set the from and to address
InternetAddress addressFrom = new InternetAddress(from);
msg.setFrom(addressFrom);
InternetAddress[] addressTo = new InternetAddress[recipients.length];
for (int i = 0; i < recipients.length; i++)
addressTo[i] = new InternetAddress(recipients);
msg.setRecipients(Message.RecipientType.TO, addressTo);
// Setting the Subject and Content Type
msg.setSubject(subject);
msg.setContent(message, "text/plain");
Transport.send(msg);
private class SMTPAuthenticator extends javax.mail.Authenticator
public PasswordAuthentication getPasswordAuthentication()
String username = SMTP_AUTH_USER;
String password = SMTP_AUTH_PWD;
return new PasswordAuthentication(username, password);
keygeneration program:
import java.io.Serializable;
     import java.security.Security;
import com.sun.net.ssl.*;
     import javax.crypto.KeyGenerator;
     import javax.crypto.Mac;
     import javax.crypto.SecretKey;
     public class Eval {
     public static void main(String args[]) throws Exception {
     String inputString ="0x0b0b0b0b";
     KeyGenerator keyGen = KeyGenerator.getInstance("HMACMD5");
     SecretKey secretKey = keyGen.generateKey();
     Mac mac = Mac.getInstance(secretKey.getAlgorithm());
     mac.init(secretKey);
     byte[] byteData = inputString.getBytes("UTF8");
     byte[] macBytes = mac.doFinal(byteData);
     String macAsString = new sun.misc.BASE64Encoder().encode(macBytes);
     System.out.println("Authentication code is: " + macAsString);

I'm not sure what's confusing you. Just generate a String (using a StringBuffer)
with the data you need and use it as the content of the mail message. If each
recipient needs different content, they'll each need a different MimeMessage
object.

I'm trying to update iTunes to 10.5.2 and I get the message that "a program required for this install to complete could not be run". I've tried all of the steps to try to resolve this (I have a PC) but nothing works. Help please!

I'm trying to update iTunes to 10.5.2. I have a Windows 7 64-bit Dell laptop, and when I try to update it, I get the message "There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor."
I went to the troubleshooting page and did all of the steps they listed: uninstalled iTunes, deleted by Temp files, even disabled AVG while I downloaded again and tried to install. I still get the same message. If anyone can help me, I would really appreciate it!

How can I use evaluate to get the instance variable in customized tag

1.
At first , I create a class called bean,and declared several params in it and do not define any getter function for the param.
class bean{
String param = "test";
SomeClass scObj = new SomeClass();
2.
The second ,I use
request.setAttribute("beanObj",new bean());
3.
And then I wanna use the customized tag to show a text box , then initialize it's value.
<salt:text name="param" value="beanObj.param">
<salt:text name="obj" value="beanObj.scObj.func()">
4.
I tried the evaluator provided by JexlContext ,Struts, JSTL and it seems that if I do not define the getter for the variable ,I can not get the bean's instance variable's value.
Expression e = ExpressionFactory.createExpression( value );
JexlContext jc = JexlHelper.createContext();
jc.getVars().put(strInitBeanName, request.getAttribute("beanObj"));
Object obj = e.evaluate(jc);
the result of the obj is null....
Can anybody recommand some other evaluator can get the value of a instance variable from an object?

do you have any other suggestion ? Nops, somebody else may have though. AFAIK, all lookups of the type
beanName.propertyNameuse reflection on the getXXX() methods to access the property.
Having said that, I guess you could write one though in a custom tag, using the same - reflection (you will ahve to rely on the java.lang.reflect.Field class quite heavily) - but that would be reinventing the wheel for most other functionality that you would have to include (like looking up the bean in scope etc)

How to get the instance id of BPEL in OSB

We have the process in OSB which will invoke the BPEL ansync process and returns success once the BPEL is invoked.
Can we refer/get the BPEL instance id in OSB by anymeans?

There is another option. You may set the unique instance name in BPEL process based on some value in the payload. From OSB you may query composite_instance table of SOAINFRA schema on the basis of instance name (title column) and/or composite name (composite_dn column) to get the value of instance id (ID column) and return it in response from OSB.

I need to get those for a specified user, but I don't want to set on a trace, that's why I'd like to use the transaction STAD.
If anyone can help, thanks in advance

How can I get the responsibility for concurrent programs

Guys,
How can I get the responsibility for a list of concurrent programs. Is there a query that I can run to get the results?
Thanks in advance,

Refer to Note: 134036.1 - WHOCANRUN.SQL - List Responsibilities That Can Run a Given Concurrent Program
https://metalink.oracle.com/metalink/plsql/ml2_documents.showDocument?p_database_id=NOT&p_id=134036.1
From the output of the query in the note referenced above, you can run "Users of a Responsibility" concurrent program then to find out the list of users who have access to a certain responsibility.

class classA {
classB objB = new classB();
class classB {

//How can I the Instance Name of Creator here?
//In this Example. The name is objA.
public class showCreator {
public static void main(String[] args) {
classA objA = new classA();
I try to instanciate an Throwable Object and use the getStackTrace method.
but all information in the stack I got Do Not contain the Instances Name.
Does any one have idea to implements this...
