Application calling another application not using states
I have a project and within two applications.
1 - I have a main application, and it got a button that will call my other application, which is within the same project.
2 - I do not intend to use the states, by mixing the code too.
3 - Is there a way to create a call to another application is similar to what is done in PopUpManager?
tks
Does the called component have to be an Application. If not, you can create a cutom component (extending from any other Flex container except Application) that holds everything you require and instantiate in your original Application on the Button Click.
If you must have an Application, you can create a separate project for the second application and compile it into a SWF. You can then load this SWF from the SWFLOADER Flex control on Button Click.

Calling another function if upate statement fails
Hi there,
I have written an update procedure and insert procedure. Is there a way of calling another function if the update statement fails? Thanks a lot for your help.
Chris
procedure update_costing(in_period in DATE,
in_project_id IN VARCHAR2,
in_user_id IN VARCHAR2,
in_thu IN VARCHAR2,
in_fri IN VARCHAR2,
in_sat IN VARCHAR2,
in_sun IN VARCHAR2,
in_mon IN VARCHAR2,
in_tue IN VARCHAR2,
in_wed IN VARCHAR2)
UPDATE TBL_COSTING
SET
HOURS_THU = to_date (in_thu, 'HH24:MI'),
HOURS_FRI = to_date (in_fri, 'HH24:MI'),
HOURS_SAT = to_date (in_sat, 'HH24:MI'),
HOURS_SUN = to_date (in_sun, 'HH24:MI'),
HOURS_MON = to_date (in_mon, 'HH24:MI'),
HOURS_TUE = to_date (in_tue, 'HH24:MI'),
HOURS_WED = to_date (in_wed, 'HH24:MI'),
WHERE PERIOD = in_period
AND PROJECT_ID = in_project_id
AND USER_ID = in_user_id;
EXCEPTION
--CALLL HERE THE INSERT FUNCTION WITH SAME DATAMEMBERS
SOMETHING LIKE THIS---
WHEN others then
insert_costing(in_period, in_project_id, in_user_id ,in_thu,in_fri,in_sat,in_sun,in_mon,in_tue,in_wed ,in_submit);
COMMIT;
END update_costing;begin
UPDATE statement
IF SQL%ROWCOUNT =0
then
INSERT statement|procedure
end if;
end;
/Hi,
i have a simple doubt over here, i read somewhere that cursor attributes can be used only as long as the cursor is open, then in the above case whiel doing the update operation, oracle implicitly will open an cursor and will do the operation and then will close the cursor, then how does SQL%ROWcount works???please revert...

To use SQL or to not use SQL ..... That is the question
A couple of posts lately have brought something to my attention that I wanted to discuss between the folks that view this forum because I believe it is important. I highly value the opinions of many of the members here so I think getting your insight would not only benefit me, but many other forum members as well.
This discussion stems from two posts:
{message:id=3786432} (Billy)
...The question that you need to ask yourself is why use such a technique? For rendering the data a specific way in the client? Well, rendering data is NOT a SQL function and in essence a result of ignorance of how to correctly use client-server. Rendering on the client is dealt with by the client itself. Using SQL to do it.. not only nasty (as many of these examples above are), but also far from optimal and efficient SQL. And in most cases, will not scale. Increase the data volume of the table queried and there will be a hefty performance knock as SQL is incorrectly used.
...>
{message:id=3914362} (Sven W.)
...For the Pivot considerations. It is usually much better not to try to do this inside the database. If you think about it. The data itself can be fetch from the database very easily. To do a PIVOT is a kind of GUI/Layout representation for this data. This should be done in the GUI Layer.
>
I tried to respond to the thread Billy posted in, so I'll cut and paste my response here:
Discussion
Where do we as database developers draw the line between the correct use of SQL or not? Or between rendering on the client and just returning data?
Now with LISTAGG, PIVOT and UNPIVOT all available to us would these be considered correct uses of SQL?
Where does this leave the TO_CHAR function? Is this considered rendering?
I'm fully expecting a fuzzy answer with something along the lines of "do the work where it makes the most sense" from a ease of development and maintainability perspective but I just wanted to ask.
Hopefully this is a valuable discussion.
Thanks!Let me give a simple example. You can store images in a table as a LOB. You can serve these images to a web browser client via mod_plsql.
However, the data is static. It requires I/O (and some hefty ones for larger images). What is the biggest performance penalty we have in Oracle? I/O? What is affected by doing I/O to read these images? The buffer cache (which will age out other data in the cache).
Where else can we store this data? The web server. At what cost to the performance of Oracle? None. Impact on web server? Heck, web servers are designed at their very core to do this!
So where is the best place to storage static images in this specific case? Not the database, but the web server.
Now simply extend this concept to the client - where is the best place to render data?
Should the data be formatted for rendering (e.g. converted into HTML) in the database layer, or should it rather be done in the presentation layer?
Now I can already hear the argument that the former is exactly what we are doing using APEX. We create dynamic HTML pages on the Oracle server side and then dish that up to the rendering layer to display.
Two issues that need to be considered. Firstly, this is not done using SQL. This is done using a procedure language called PL/SQL - not using native SQL. PL/SQL in this case is used exactly as Java or PHP or Perl or any other "+app layer+" language would be used. It only happens that PL/SQL resides in the database too. But do not mistake it for what it really is - the application layer.
The second issue drives home the point that even in 3 tier client server, the application layer is not the best place to do the formatting for the rendering layer. Web 2.0 aka AJAX.. Where the app layer delivers a dynamic rendering engine (as Javascript) to the rendering layer. After which rendering and formatting are done solely inside that rendering layer. And interaction between that and the app layer is requests for new/fresh data to be rendered.
Why is AJAX becoming so popular? Key issues and concepts like performance, and a rich client interface and so on.
This all points that the fundamental principle of using the rendering layer to do its thing and using the SQL layer to do its (separate and different) thing, still holds true.
Yes, we may not always stick to this principle - as we do with doing the rendering (creating HTML) in PL/SQL using APEX for example.. but this is not because the principle is unsound. It is because of technology reasons (different browsers, different behaviour), lack of support for W3C standards (hello IE) and so on.
It is only recently that these problem areas have been meaningfully addressed.. and why rendering frameworks like extJS is the (rendering layer) future of 3 tier client server.
If the concept of using SQL to perform rendering and formatting had any substance.. then there would have been a lot of resistance to AJAX for example. The reverse is true.. as we all want to use SQL to do SQL and want the rendering layer to do its thing without us having to code in SQL to specifically support rendering and formatting. It is clunky. It slows down the SQL (every formatting function is a tiny overhead that adds up). It does not bode well for maintenance and changes to the presentation layer. And all those tiny overheads can spell doom for scalability.
I do not see any gray lines here, or a question of "+opinion+", or "+it depends+". The architecture is clear. The fundamentals are sound.
The real issue is how we choose to apply these. But (the "+incorrect+") application (of these fundamentals) does not invalidate the fundamentals. -
How do I "call" a skype user using skype name
Completely new to SKYPE -- how does one call another skype user using the party's skype user name
Hi, tdenson, and welcome to the Community,
Confirming that yes, indeed, you and other contacts must exchange a contact invitation before you can call one another on Skype. In other words, if you send a contact invitation, the recipient must accept it first.

I am trying to burn a music cd on iTunes, but I am getting an error that reads that the cd burner is being used by another application. I know that I am not using the cd burner for anything else. I have restarted the Mac and nothing. Any ideas?
One other thread said it was fixed by waiting till prompted by iTunes to insert the blank disk, instead of putting it in first. Does that work? Found a number of hits on this Googling.

Calling Console Application that uses WebBrowser from SQL Server - Not Running
Hi there. I am working in a program automation that needs to get files from a website and put it in a database. It is done but as I need a console application and need webbrowser that comes from Windows Forms, I am trying to call it from the SQL Server using
the xp_cmdshell but when it runs the .exe, it execute the block that is before the Application.Run() command but when it reaches this line, it stay running on Task manager but it not execute my code. How can I fix this? I had first created a Windows form application
but it was not working anyway and then I tried a console application and then I use the [STAThread] and Application.Run(). At least it runs the file from SQL Server but is not executing all my code, I think that it stops on Application.Run() line. Any help
will be very useful.
Thanks for now.Thanks for the response. What I mean is that it just run the part of the code that is just using the Console, that's the code:
// Main Method
[STAThread]
public static void Main()
clearDatabase(myConnection);
Console.Title = "Suframa Itens Robot";
//If log file exists, it is deleted
if ( File.Exists(@"suframaLog.txt") )
File.Delete(@"suframaLog.txt");
wb.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(loginWebsite);
try
//It is called as the program uses the WebBrowser Class from Windows Forms namespace
//and it is a console Application
Application.Run();
catch ( Exception ex )
Log(ex.Message);
As you can see, I call a function on start named ClearDatabase, when I call the file from sql server it executes, the tables are cleared, but what I think is that the problem stop when reach the line Application.Run() as it is the line that allows the remaining
code to execute as it uses events from WebBrowser class.
It is a program automation that needs to get a lot of files from a website that needs login and read line by line from the files and put on server, if I call it from the executable it runs fine, the only problem is when calling from SQL Server, Do you know
how to fix this?
Thanks. -

Application Exception using @Application not working
I'm trying to create 2 business application exception using the @Application annotation on my 2 java exception class. The first exception is a StarException class that extends java.lang.Exception (per ejb 3.0 spec). Below is snippet of the class.
@ApplicationException(rollback=true)
public class StarException extends Exception {...}.
As you can tell that this is a check exception and will rollback transaction when it occurred. I have another exception class called StarRuntimeException that extends java.lang.RuntimeException. This is also mention on ejb 3.0 spec and is useful if you don't want to catch the exception on the server side and just throw it and the client will receive such application exception class. Below is a snippet of the class ...
@ApplicationException(rollback=false)
public class StarRuntimeException extends RuntimeException {...}.
By the way I'm using this exception in my wls 10.3 webservices stateless beans (jax-rpc 1.1). Some of the methods throws these 2 exceptions.
There are 2 problems with this application exception during runtime on the client side.
1. Regarding StarException, the client can catch this exception when the webservice method throws this exception. The problem is that the error messages is null. Tried both getMesssage() and getLocalizedMessage() are all null.
2. Regarding StarRuntimeException, the generated client stubs and artifacts does not even throw this exception, therefore it will not the caught. This exception is wrapped inside RemoteException instead.
Your help are needed. ThanksOk. I figured it out. The url rewrite was missing in the config. Put it there and its working now.

How to interface a tuxedo app with another application that uses tcp/ip socket messaging
How would you interface a tuxedo app with another application that
uses tcp/ip socket messaging? I have a vendor product that offers
a tcp/ip message interface, and would like to know how best to
integrate it into a tuxedo application. I could write a C application
that listens and accepts incoming request from the vendors application,
and then make a tuxedo client call to a service. But this doesn't
allow me to control the listen thread through tuxedo. The C application
would have to be started seperately and would not take advantage
of the tuxedo restart facilities etc of a tuxedo service.You can make an empty server only with tpsvrinit that starts your client
listeners and a tpsrvdone that stops them. Be carefull with sharing ipcs
between processes, or your clients may get puzzled!!!
Another choice can be builting a custom WSL/WSH but I haven't done
this yet and I don't know exactly the troubles related with making them.

i have two apple id accounts ,when i used to update application it used to prompt a default id (the old one) and if the application was downloaded using the other id i would cancel and it would prompt the other id but not any more .
it just prompt the old id which im not signed in with im signed in using the new id and when i cancel nothing happens and when i try to update applications separately i have the same problem .
im signed in using the new id
the old one is my wife's so i can't delete it
the problem happens when i update all or each application by its own
using ios 5.0.1 on a iphone 3gs
the applications are downloaded using both the new and old id's
any help will be greatly appreciatedِThese are user-to-user forums, you are not talking to Apple here and they don't monitor these forums - I've asked the hosts to remove yout account ids from your post.
In terms of combining accounts it's not currently possible to do so, nor to copy/transfer content from account to another. -
I am having a problem with the new iTunes store. I can connect my ipod, and it will show that it is syncing. Once the sync is complete on iTunes, my ipod still shows that it is connected, do not eject. I have not had a problem with this until the new verision of iTunes. When I go to eject my ipod, it tells me that it can't eject due to application being used in another program. I did receive an ipad 2 for Christmas, that I also sync with iTunes, but only the ipad shows up in my devices on the site, what happened to my ipod device and how to add it back to devices?

Hi,
I Published a report on the report server but it's not showing in the internal application we use to access reports. The name of the application we use is called MAMA and this application has access to all the reports on the SQL report server. My email is
[email protected] my cell phone number is 201-888-7952.
Thanks.Hi Roger,
Based on my understanding, you publish a report on the report server. When you access reports with internal application, the report doesn’t display, right?
In your scenario, since you mentioned you have published the report to report server, please go to report manager, check if you can see the published report and open the report properly. If the published report is displayed on report manager, it should not
be the issue in Reporting Services. In this scenario, since the MAMA application has established connection with on report server, it may not update items on report server after you publish your report onto report server. So please try to “refresh” in MAMA
or reconnect the report server. If issue persists, I suggest you contact the MAMA application vendor to get some more effective advices.
If you have any question, please feel free to ask.
Best regards,
Qiuyun Yu
