Event propagation from child application to main application

Hi,
      I am using SWFLoader to load third party component into our main application.we are trying to create annotation feature on top of child application.for that main application needs to receive events e.g. mouse events from child application.can anyone suggest whether this is possible ?
      I found pdf doc from help of SWFLoader component on flex developmenent center.It has an example in which child application uses SystemManager to register event listner for main application.so is it that we need to register listener from child application so main application receive events ?
   Thanks in advance.
Thanks and regards,
Rakesh Parmar

If you examine the urls and the domains are the same then you don't have a cross-domain problem, but then your symptoms remain unexplained.
Note that Flash just checks the text of the domain/sub-domain so http://localhost/ is different from http://10.0.0.127/ or whatever its IP equivalent is.

Event propagation

Hi,
SAP has standard functionality of event propagation from FU to FB and vice versa.Now if I want to stop event propagation or event cascading functionality from FB to FU do I need to remove any code logic check in the extractor? Can you elaborate in details here.
Secondly how does preprocessing functionality help in ENM functionality. What specific checks can eb brought about if w ewant to implement this functionality

Hi Dipak,
Extract the FU number as TOR_TEC tracking id from TM shown below
FU EH TRacking ID table
Tr.Code.Set
Tracking id
FU
123456
TRQ
987563
TO
458796
TOR_TEC
123456
Define the Tracking id Code Set(TOR_TEC) in Event reporting items under event message profile , configure only to particular internal event code which does not requires event propagation to FB.
Above configuration supported only when the event posted via EM WebUI,
you have to apply the same logic in BADI for interface event posting.

Question re-posted: Way to get events from outside application

Hello,
FatCo asked this question but has not got a reply. I have the same question, so I re-post it, hoping someone could give us help. How can we write JNI code to do it on a Windows OS? Assume appliction 2 is a Internet Explorer.
Thank you!

Hello,
is there a way to get events from other applications, either native or java applications?
For example application 1 (Java or not) is getting minimized, is there a way to notice application 2 (Java) about that?

I am not really a Windows programmer so I cannot say how you can get the event notification in C(++) but if you can get it there then there should be no particular problem communicating that information to Java.
This might take the form of creating a thread (all threads are native threads on Windows) which blocks on receiving this event and then notifies the rest of the application somehow, maybe by setting a global flag, using Object.notify() to wake up some other thread to do the processing, or simply by calling a Java method to do all the necessary handling before returning. But there is nothing special about this part.
It all depends on how you can receive the event notification in C++.

How to post audit event from my application ?

Hi All,
I'm newbie in weblogic(server) field. I'm working on audit trail for my application. We are using weblogic server8.1 SP4.
I read thru the documentation in weblogic site and understood the default and custom auditing providers/auditing events and how to configure them from the admin console.
I would like to know how to programatically invoke/trigger/post that audit from wherever I want from the application.
Hope I'm clear.
Any help in this regard is highly appreciated.
Thanks
Viji

If you find out.... I'm curious too.

Removing AddressBar, StatusBar from Default Application Window

Hi,
I want to hide address bar from default application window!
This application would be triggered from a link in another (web dynpro / non-web dynpro) application.
And user should not be able to see where he is gets navigated.
So, is there anyway we can hide address bar from default application window of a Web Dynpro application?
Please help.
Thanks and regards,
Amey Mogare

Hi Naga,
I already tried this code. But what it does is, it opens same window as new window in main application window.. so on screen I see two windows.. one parent window with URL clearly seen and 2nd child window which doesn't have address bar
So this is not as I need.
Are you getting my point?
Thanks and regards,
Amey Mogare

Separating heavy duty business process from web application

I'm working with a web application that just runs in a Servlet container, Jetty actually. I'm wondering what the best way to separate resource intensive processes, such as a search indexing process, from the main web application. These resource intensive processes might run at scheduled times, or they might be triggered by the events in the web application. I assume the second thing might incur much more complications on the solutions. I have a lot of questions about this, but for now, I'd just like to have some folks point out the common solutions. Changing to a EE application server is NOT an option.

Couple of questions:
1) What's the benefit of going to another app if you're still on the same server? I'm not being coy, I'm just trying to get a feel for the pros and cons. You could always run something on a timer from within the web application. Is there a performance benefit from being in another JVM? Then run it on the same server. No need to run it on another server if a separate JVM will do it for you.
2) How would you communicate with the main app if you needed to receive events or something? RMI?You stated it was on a timer. There is no need to be on the same server to run things from a timer. If it needs to be event driven a simple way would be to set up a separate instance of Tomcat (or Jetty) on the same or different server. Refactor out what ever the offending code is into separate servlet and have your main app just send the events off to the other instance.
There are a lot of ways to go about this. They depend on what your needs are.

Loading web pages from an application

Hi All
I've tried hunting on this web site for info about how to show an html page from an application. Unfortunatley I couldnt find anything.
So how do I fire up a web browser, and load in a specified web page?
I can get a URL pointing to a file on my system ie File:c:/MyDoc/Help.htm, but am unsure what I need to do next.
Any advice welcome.
Cheers

The Help Link from the Application Pages Does not Work for Peoplesoft Campus Solutions 9.0

Hi everyone.
I have a problem, I have been trying to set up the Help Link from the Application Pages for Peoplesoft Campus Solutions 9.0 according to the instructions given in the Document: http://docs.oracle.com/cd/E17566_01/epm91pbr0/eng/psbooks/EnablingtheHelpLinkfromApplicationPages.pdf , (referenced in the Doc ID 1289101.1, E-PB: How to Set Up the Context Sensitive Help with Hosted PeopleBooks using Universal Linking).
I follow the instructions of that document carefully:
I go to: PeopleTools -> Web Profile -> Web Profile Configuration
    2. Then I choose the Web Profile: "Development".
    3. Then Change the value for the Help URL field by entering the following URL format: http://www.oracle.com/pls/topic/lookup?id=%CONTEXT_ID%&ctx=hrcs90r5 , the ctx parameter selected is the one that correspond to the Campus Solutions (hrcs90r5) according to the Product Line Code Table (ULinkID) especified in the mentioned document.
    4. Stop the Web Domain and Clear cache.
    5. Start the Web Domain again.
After setting up the Web Profile Configuration I test the help links, thas is why I click in the Help link in any Peoplesoft CS 9.0 Application Page (modify a person), but the next error message appears: "We're sorry, the topic you requested was not found.".
I tried many combinations with the ctx parameters URL but it does not work yet.
I did the same test, but this time using the Help URL field with a HRMS ctx parameter by entering the following URL format: http://www.oracle.com/pls/topic/lookup?id=%CONTEXT_ID%&ctx=hcm92pbr5 , and It works fine !!!
According to the previous test you realize that It works with HRMS ctx parameter but not with Campus Solutions 9.0 ctx parameter, Does anybody know what else can I do ? Am I doing anything wrong or missing? or maybe the Oracle's ctx parameter for Campus Solutions URL It is broken simply.
Thanks for you help and feedback.

2799444 - The page you are testing with appears to be a Workforce Administration page. Is that correct?
The CS PeopleBooks would only work for CS pages, e.g.: try navigating to Main Menu > Campus Community > Personal Information > Add/Update a Person
Also, you can use multiple ctx parameters:
E.g.: http://www.oracle.com/pls/topic/lookup?id=%CONTEXT_ID%&ctx=hrcs90r5&ctx=hcm92pbr5&ctx=pt852pbh2
This way the help would work for the HR related pages like Workforce Administration, Campus Solutions pages like Campus Community and also PeopleTools pages like Web Profile Configuration. Hope this clarifies your question. Thanks!

How to pass a CString from one application to another application using WPARAM/LPARAM in sendmessage fn.

I have two different application A & B. I am trying to send a message from A to B. In application A , I get the window handle of application B and call postmessage fn to post a message to application B. While posting the message I am trying to send a
cstring in wparam parameter so that it can be accessed in the message handler.
Code in Application A:
void CTestApplnDlg::OnBnClickedOk()
CString csProcessName = _T("FSAPP.exe");
CFSProcess objProcess;
HWND hFSWnd = NULL;
if(objProcess.GetProcessHandle(csProcessName, hFSWnd))
CString * csMessage = new CString(_T("This is message from A application."));
::PostMessage(hFSWnd, WM_THIRD_PARTY_NOTIFICATION, (WPARAM)csMessage
, NULL);
In the other application in the event event handler I try to do the following :
LRESULT CMainFrame::OnProcessThirdPartyNotification(WPARAM wParam, LPARAM lParam)
CString* csMessage = (CString*)wParam;
if(csMessage )
AfxMessageBox(*csMessage);
return 0L;
In the message handler fn, the variable csMessage is pointing to a address but the value is a bad ptr. On accessing the variable like *csMessage it crashes. I have created the variable in heap when the message is posted. So I hope the variable will be in memory.
Pls help.

The ultimate problem is that when you place a CString in a wparam like that you are putting an address. That address only has meaning in the first program. Your second program cannot access the first programs memory (this is good, otherwise misbehaving
programs could take down all applications in Windows). But it does make transferring data between programs more complicated.
Some messages like WM_COPYDATA will copy a data buffer from one process to another and are appropriate for what you are trying to do, but a custom message like
WM_THIRD_PARTY_NOTIFICATION is not one of them.
By the way your example has a memory leak as well since you would have no way to ever clean up the string you allocate in OnBnClickedOk

Read this article in order to get an idea about Java Stored Procedures.
Oracle Developer JAVA STORED PROCEDURES
Simplify with Java Stored Procedures
By Kuassi Mensah
Use Java stored procedures to bridge SQL, XML, Java, and J2EE and Web Services.
Stored procedures allow a clean separation of persistence logic that runs in the database tier from business logic that runs in the middle tier. This separation reduces overall application complexity and increases reuse, security, performance, and scalability.
A major obstacle, however, for widespread adoption of stored procedures is the set of various proprietary, database-dependent implementation languages that different database vendors use. The use of Java-based stored procedures fixes this concern. Oracle has implemented ANSI standards that specify the ability to invoke static Java methods from SQL as procedures or functions. This implementation is called simply "Java stored procedures."
In this article, you will learn how Java stored procedures help simplify and increase the performance of your business logic and extend database functionality. I'll show how Oracle enables the use of Java stored procedures within the database. I'll also look at how Java stored procedures access data, and show how to create a basic Java stored procedure.
PL/SQL or Java
When you think of Oracle stored procedures, you probably think of PL/SQL. Oracle, however, has provided Java support in the database since Oracle8i, to offer an open and portable alternative to PL/SQL for stored procedures. I can hear the $64,000 question: "How do I choose between PL/SQL and Java? Should I forget all the things I've been told about PL/SQL and move on to the greener Java pastures?"
Both languages are suitable for database programming, and each has its strengths and weaknesses. In deciding which language to use, here's a general rule of thumb:
Use PL/SQL for database-centric logic that requires seamless integration with SQL and therefore complete access to database objects, types, and features.
Use Java as an open alternative to PL/SQL for database independence, but also for integrating and bridging the worlds of SQL, XML, J2EE, and Web services.
OracleJVM Lets You Run Java within the Database
Since Oracle8i, Release 1 (Oracle 8.1.5), Oracle has offered a tightly integrated Java virtual machine (JVM) that supports Oracle's database session architecture. Any database session may activate a virtually dedicated JVM during the first Java code invocation; subsequent users then benefit from this already Java-enabled session. In reality, all sessions share the same JVM code and staticsonly private states are kept and garbage collected in an individual session space, to provide Java sessions the same session isolation and data integrity capabilities as SQL operations. There is no need for a separate Java-enabled process for data integrity. This session-based architecture provides a small memory footprint and gives OracleJVM the same linear SMP scalability as the Oracle database.
Creating Java Stored Procedures
There are a few steps involved in turning a Java method into a Java stored procedure. These include loading the Java class into the database using the loadjava utility, and publishing the Java methods using a call specification (Call Spec) to map Java methods, parameter types, and return types to their SQL counterparts. The following section shows how to do this.
I'll use a simple Hello class, with one method, Hello.world(), that returns the string "Hello world":
public class Hello
public static String world ()
return "Hello world";
The Loadjava Utility
Loadjava is a utility for loading Java source files, Java class files, and Java resource files; verifying bytecodes; and deploying Java classes and JAR files into the database. It is invoked either from the command line or through the loadjava() method contained within the DBMS_JAVA class. To load our Hello.class example, type:
loadjava -user scott/tiger Hello.class
As of Oracle9i Release 2, loadjava allows you to automatically publish Java classes as stored procedures by creating the corresponding Call Specs for methods contained in the processed classes. Oracle provides Oracle9i JDeveloper for developing, testing, debugging, and deploying Java stored procedures.
The Resolver Spec
The JDK-based JVM looks for and resolves class references within the directories listed in the CLASSPATH. Because Oracle database classes live in the database schema, the OracleJVM uses a database resolver to look for and resolve class references through the schemas listed in the Resolver Spec. Unlike the CLASSPATH, which applies to all classes, the Resolver Spec is applied on a per-class basis. The default resolver looks for classes first in the schema in which the class is loaded and then for classes with public synonyms.
loadjava -resolve <myclass>
You may need to specify different resolvers, and you can force resolution to occur when you use loadjava, to determine at deployment time any problems that may occur later at runtime.
loadjava -resolve -resolver "((* SCOTT) (foo/bar/* OTHERS)
(* PUBLIC))"
Call Spec and Stored Procedures Invocation
To invoke a Java method from SQL (as well as from PL/SQL and JDBC), you must first publish the public static method through a Call Spec, which defines for SQL the arguments the method takes and the SQL types it returns.
In our example, we'll use SQL*Plus to connect to the database and define a top-level Call Spec for Hello.world():
SQL> connect scott/tiger
SQL> create or replace function helloworld return
VARCHAR2 as language java name 'Hello.world () return
java.lang.String';
Function created.
You can then invoke the Java stored procedure as shown below:
SQL> variable myString varchar2[20];
SQL> call helloworld() into :myString;
Call completed.
SQL> print myString;
MYSTRING
Hello world
Java stored procedures are callable, through their Call Spec, from SQL DML statements (INSERT, UPDATE, DELETE, SELECT, CALL, EXPLAIN PLAN, LOCK TABLE, and MERGE), PL/SQL blocks, subprograms, and packages, as well as database triggers. The beauty of Call Spec is that stored procedure implementations can change over time from PL/SQL to Java or vice versa, transparently to the requesters.
Call Spec abstracts the call interface from the implementation language (PL/SQL or Java) and therefore enables sharing business logic between legacy applications and newer Java/J2EE-based applications. At times, however, when invoking a database-resident Java class from a Java client, you may not want to go through the PL/SQL wrapper. In a future release, Oracle plans to provide a mechanism that will allow developers to bypass the Call Spec.
Advanced Data-Access Control
Java stored procedures can be used to control and restrict access to Oracle data by allowing users to manipulate the data only through stored procedures that execute under their invoker's privileges while denying access to the table itself. For example, you can disable updates during certain hours or give managers the ability to query salary data but not update it, or log all access and notify a security service.
Sharing Data Logic Between Legacy and J2EE Applications
Because legacy applications and J2EE applications both invoke stored procedures through the Call Spec, the same data logic can be shared between J2EE and non-J2EE worlds. Thanks to Call Spec, this data logic can be shared regardless of the implementation language used (whether PL/SQL or Java).
Autogeneration of Primary Keys for BMP Entity Beans
When using BMP for EJB entity beans, a bean instance can be uniquely identified by the auto-generated primary key associated with the newly inserted data as a return value for ejbCreate(). You can retrieve this value within ejbCreate() in one database operation by using a stored procedure that inserts the corresponding data and retrieves or computes the primary key. Alternatively, you could insert the data and retrieve the corresponding key (or ROWID) in one SQL statement, using the RETURN_GENERATED_KEYS feature in JDBC 3.0. However, the stored procedure approach is more portable across JDBC driver versions and databases.
You can implement this pattern with these three steps:
Create the Java stored procedure, defining a public static Java method insertAccount() within a public GenPK class. This method will insert data, compute a unique key (by passing out a sequence number), and return the computed key as primary key.
Define the Call Spec.
CREATE OR REPLACE PROCEDURE insertAccount(owner IN
varchar, bal IN number, newid OUT number)
AS LANGUAGE JAVA NAME 'GenPK.insertAccount(
java.lang.String [])';
Invoke the stored procedure within ejbCreate().
Public AccountPK ejbCreate(String ownerName, int balance) throws CreateException
try {
CallableStatement call = conn.prepareCall{
"{call insertAccount(?, ?, ?)}"};
return new AccountPK(accountID);
Custom Primary Key Finders for CMP Entity Beans
Finder methods are used for retrieving existing EJB entity bean instances. Primary key finders allow you to retrieve a uniquely identified EJB instance. For CMP entity beans, the EJB container automatically generates the primary key finder findByPrimaryKey() method, based on declarative description. In some situations, however, you might need more control; for example, you may need a specialized finder such as findByStoredProcKey(). In these situations, you can use Java stored procedures in conjunction with an object relational framework (such as Oracle9i Application Server [Oracle9iAS] TopLink) to implement a custom primary key finder method. After you define the EJB finder as a REDIRECT or NAMED finder, TopLink will generate the SQL query for retrieving the bean instance.
Data-Driven EJB Invocation
In a data-driven architecture, business logic invocation can be triggered as a result of database operations (such as inserts, updates, or deletes). A Java stored procedure implementing the data logic can be declared as a database trigger to invoke EJBs running in a middle-tier J2EE application server. You can make EJB calls by using either standard remote method invocation (RMI) over Interoperable Inter-ORB Protocol (IIOP), using a J2EE 1.3 compatible server, or RMI over a vendor-specific transport protocol (such as ORMI with Oracle9iAS/OC4J or RMI over T3 with BEA WebLogic). Each application server vendor has its own optimized protocol while providing RMI over IIOP for interoperability. Oracle9iAS supports both RMI calls over IIOP and ORMI protocols.
Data-Driven Messaging
Oracle9i Database embeds Advanced Queuing (AQ), which is an integrated, persistent, reliable, secure, scalable, and transactional message-queuing framework. Oracle exposes AQ features to Java developers through the standard Java Messaging System (JMS) API. Java stored procedures can invoke AQ operations through the JMS interface to allow fast, intra-session, scalable, data-driven messaging.
Java stored procedures can use JMS to invoke AQ operations. You can implement this pattern in four steps:
Create and start the JMS Queue (to do so, embed the following operations within a SQL script):
execute dbms_aqadm.create_queue_table(queue_table =>
'queue1', queue_payload_type =>
'SYS.AQ$_JMS_TEXT_MESSAGE', comment => 'a test queue',
multiple_consumers => false, compatible => '8.1.0');
execute dbms_aqadm.create_queue( queue_name => 'queue1',
queue_table => 'queue1' );
execute dbms_aqadm.start_queue(queue_name => 'queue1');
Create the Java stored procedure (a code snippet is shown):
public static void runTest(String msgBody)
try
// get database connection
ora_drv = new OracleDriver();
db_conn = ora_drv.defaultConnection();
// setup sender (cf online code sample)
// create message
s_msg = s_session.createTextMessage(msgBody);
// send message
sender.send(s_msg);
s_session.commit();
// receive message
r_msg = (TextMessage) receiver.receive();
r_session.commit();
// output message text
String body = r_msg.getText();
System.out.println("message was '"+body+"'");
Create the Call Spec:
create or replace procedure jmsproc (t1 IN VARCHAR)
as language java name 'jmsSample.main (java.lang.String[])';
Invoke the stored procedure:
call jmsproc('hello');
Database-Assisted Web Publishing (Cache Invalidation)
One of the common issues application architects must face is how to cache database information reliably to increase overall system performance. JCACHE is an upcoming standard specification (JSR 107) that addresses this problem. It specifies an approach for temporary, in-memory caching of Java objects, including object creation, shared access, spooling, invalidation, and consistency across JVMs. It can be used to cache read-mostly data such as product catalogs and price lists within JSP. Using JCACHE, most queries will have response times an order of magnitude faster because of cached data (in-house testing showed response times about 15 times faster).
In order to track all the changes to the origin data and refresh the cached data, a Java stored procedure is attached to a table as a trigger. Any change to this table will result in the automatic invocation of this stored procedure, which in turn will call out a defined JSP to invalidate the JCACHE object that maps its state to the database table. Upon invalidation, the very next query will force the cache to be refreshed from the database. Next Steps

Extending Database Functionality
One of the great things about running Java code directly in the database is the ability to implement new functionality by simply loading the code or library and using the Call Spec to make the entry points (public static methods) available to SQL, PL/SQL, Java, J2EE, and non-Java APIs. Oracle9i Database customers can easily extend database functionality. Oracle itself leverages this capability for new utilities and packages such as the XML Developer Kits (XDKs).
Bridging SQL, PL/SQL, Java, J2EE, .NET, and XML
The Oracle XDK is written in Java and exposes its public methods as Java stored procedures, extending the database's XML programmability. SQL, PL/SQL, Java, J2EE, and non-Java (.NET) business logic all have access to the XML parser, the XSLT processor, the XPath engine, and XML SQL Utility (XSU).
The XML parser is accessible through the xmlparser and xmldom packages. XSU is a Java utility that generates an XML document from SQL queries or a JDBC ResultSet, and writes data from an XML document into a database table or view. Using XSU, XML output can be produced as Text, DOM trees, or DTDs. XSU is exposed to PL/SQL through the dbms_xmlquery and dbms_xmlsave packages.
Conclusion
The integration of the Oracle database with a Java VM enables the creation of portable, powerful, database-independent data logic and persistence logic. The loose coupling of business logic that runs in the middle tier with data logic that runs in the database tier improves application scalability, performance, flexibility, and maintenance.

Creating an Applet from an Application

So i'm developing my own version of the '80s Space Invader game for class, and one of the requirments is that we have to turn in an application, but also post an Applet version on a website. The game is pretty much done, but I am having trouble creating the Applet from the Application. I've done most of the stuff that i thought you were supposed to do. The thing is, it will run whenever i use the appletviewer from the dos prompt just like it does when i'm running the application. However, when Ii try to view it in an actuall explorer window, it wont load.
The way the program was designed, it had a "SpaceInvaders" class that had the main method, which only had about 4 lines. Then i had a DrawFrame class that extended JFrame, and that had the bulk of the code in it. The main method of the SpaceInvaders class had a "DrawFrame frame = new DrawFrame();" statement, and then a couple set.whatever statements. to change it to an applet, i just commented out the whole of the SpaceInvaders class, then i renamed the DrawFrame class to "public class SpaceInvaders extends JApplet" changed the consructor to the "init()" method, and commented out the setSize and setTitle statements, and also i imported java.applet.*;
when i try to run the html file in firefox, all i get is the frame with a little red 'X' in it, and at the bottom it says "Applet SpaceInvaders notinited"
any help, ideas, or tips would be greately appreciated. Thanks in advance, and if you need any more info, let me know.

i created a very simple applet:
import java.applet.*;
import java.awt.*;
* The HelloWorld class implements an applet that
* simply displays "Hello World!".
public class HelloWorld extends Applet {
    public void paint(Graphics g) {
        // Display "Hello World!"
        g.drawString("Hello world!", 50, 25);
}and it ran just fine inside of a browser. I've also ran other applets that should be very similar to mine, but still mine doesn't work.

Calling a bounded task flow (that uses fragments) from another application

Hello,
I'm currently having difficulties calling a task flow located inside another application.
I have application Console which is my main application in which I would like to run other applications within. Inside this Console I have it divided into splitter windows and inside them I have regions. My goal is to be able to call a task flow from another application inside one of these regions but so far I'm having no luck.
My first problem occurred when I created a 'local' task flow to make a call to another application's task flow. When I set the properties to the task flow call, it gave me an error that it could not find the .XML file for that task flow when I ran the Console application. I then proceeded to copy that .XML from the remote application into the Console's WEB-INF directory and I seemed to get a bit farther. The error I get now is saying that I cannot run a task-flow that uses fragments. It's essentially trying to run that task flow as an entirely new page instead of inside the region that it's bound to. It's NOT a dynamic region (although that's the end goal here). So I then changed the other application's task flow to simply display an entire page rather than fragments inside a region and voila, it works..... kind of.
To recap how I was able to call another application's task flow inside the Console:
- I had to manually copy the task flow xml file into the Console WEB-INF directory
- I had to change the task flow so that it didn't use fragments
- I have called the task flow but I lose my console page entirely, no more regions or splitters so I'm back to square one.
If anybody has any suggestions, hints, tips or anything, send them this way and I will be forever greateful.
Thanks,
Mark

Thanks for your response Frank.
Unfortunately the problem seems to be greater than that. I've been able to package task-flows into a jar library and tried importing them that way with no luck.
I'm simple trying to call an external task-flow to run inside a region which is inside a splitter panel that I call my console.
Any other ideas ?

Hi,
To create subsite using event receiver in SharePoint Empty Project, you can refer to:
Sharepoint 2010 event handler to create subsites
To display a PoPup to show the progress creation, you can use: MessageBox.Show("Hello, world.");
More information:

Error in Event viewer - COM Server application security Issue

Dear All,
I am installing one software on windows cluster environment. But while installing I am getting continuous error in System in Event Viewer as 'The application-specific permission settings do not grant Local Activation permission for the COM Server application
with CLSID {xxxxxxxxxxxxx} and APPID {xxxxxxxxxxxxx} to the user NT SERVICE\SQL Server Distributed Replay Client SID (S-1-5-80-3249811479-4343554-65656-65665) from address LocalHost (Using LRPC). The security permission can be modified using the Component
Services administrative tool.'
I have seen in component services, that app ID I am getting for DReplayController service. On security tab if I want to give permission to that particular user then to which user I want to add in 'Launch and Activate permissions'. I am not getting 'SQL Server
Distributed Replay Controller' user in list.
So, please help me.
Thanks in advance.

Waiting data file from another application

Hi,
I would appreciate your help with the following problem:
I am executing an application from within my java application as a process and waiting until it finishes. I need the results file from that application to be read from within mine. The problem is that this application creates other processes that dump the results files long after its main process has informed my application about its successfull execution. The question is, how can I be sure that the particular result files are already written to the end and closed by those hidden for me processes.
Thank you in advance!

If I understood well, you're saying that :
1) you have to wait for the results before proceeding with your application, and you do not have control over the writing processes so that you cannot use some kind of async notification (e.g JMS),
2) Even when your app is informed of the success of the operation, at that exact time you are not getting the result files you need to proceed. So being informed of success and being able to proceed happen at different times ?
In that case, the one solution that comes to mind is 'polling' :
When you're being informed of success, spawn a separate thread (to prevent app freezing) that continuously polls the result files in a while loop.Or, if you don't want to waste CPU cycles, make the thread sleep for a while and try again at regular intervals.
Less than perfect solution, but I don't see any other alternative ..
You'll then have to figure out what to do with your app while you're trying to get the results...
Hope this helps a bit.
