Qt simple example crash-on-exit

It's my first time toying I wrote this piece of code just to #include <QtGui>
int main(int argv, char **args)
QApplication app(argv, args);
QVBoxLayout layout;
QWidget window;
window.setLayout(&layout);
window.show();
return app.exec();
Saved as app.cpp in qttest2 directory The I issued:
qmake -project; qmake; make
All went OK, then, testing the app, $ ./qttest2
*** glibc detected *** ./qttest2: ======= Backtrace: =========

or in the build process? And what?

The problem is that you allocated your QVBoxLayout object on the stack, though it's supposed to be on the heap so that the Qt framework can free the memory on its own once the object is no longer needed.

Explain User exit concept with simple example

Hi friends
I am new member of this forum & i am learning ABAP.
Kindly send me user exit concept with simple example to my mail ID so i can able to use it.
mail ID [email protected]
thanks in advance
Thanks & Regards

Code SE18 is used to Identify the BADI available.
Look for the string 'CL_EXITHANDLER' in the standard program. This is a class which has a method 'GET_INSTANCE' which is used to trigger BADI's from the Standard Program. The interface parameter for this static method 'EXIT_NAME' is used to pass the BADI to the method.
Open Standard Program and do a global search 'CL_EXITHANDLER'.
SE18 > give the BADI name found through above search.
CUSTOMER_ADD_DATA > which has a method SAVE_DATA.
T.Code SE19 is used to Implement BADI.
SE19 > give the implementation name > Give the Definition name as CUSTOMER_ADD_DATA and the Short Text.

What are BAdIs?
-> is an anticipated point of extension these points act like sockets and exist in the original source code
-> based on ABAP Objects. BAdI defines an interface that can be implemented by BAdI-implementations that are transport objects of their own
->Important! There are 2 roles: Enhancement Option-provider & Implementer.
-> In the above context, Enhancement Implementation can be done only if option (hook) is provided by the Option-provider. In simple words there are no implicit BAdIs.
Note: In the following slides, Definitions are created so as to understand the method of BAdI definition & for example purpose. As stated above this is the role of Enhancement Option-Provider.
Classic BAdIs already exist since SAP Release 4.6
BAdIs have been Re-implemented in ECC7.0 under the new Enhancement Framework & Switch Framework
Classic BAdIs
To understand what a powerful pattern a BAdI is, we will now define & then implement a BAdI
BADI Class is created automatically.
The various options are described below in detail:
1. Enhanceable: Enhanceability of filter types can only be specified for filter-dependent BADI definitions under very special conditions. For example, the domain belonging to the filter type must be linked with a value table that is of the type E or G. A BADI implementation can then be created in one step by creating a new filter value that is automatically entered into the value table at save and also copied into the transport order of the BADI implementation. In addition, it is also possible to create a new filter value and, at the same time, a BADI implementation with the same name. Naturally, you can also specify existing filter values.
You should select this feature if there is a prerequisite that a new filter value is created together with a new BADI implementation - that is, that BADI implementations are not created solely with existing filter values, although this, too, is possible.
2. Multiple-Use
3. Filter-Dependent
Instance Methods can access all of the attributes of a class and can trigger all events of a class. Static Methods can only access static attributes and static events.
Exceptions:
Events:
Events can be defined in classes or in interfaces. Corresponding methods can trigger these events with the RAISE EVENT statement. Each class (or interface) that is going to handle the corresponding event must implement a relevant handler method, and register it using the SET HANDLER statement. When an event occurs, the system calls all of the handler methods registered for that event.
Like method definitions, events have a parameter interface. The only difference is that events may only have EXPORTING parameters.
BADI : Businees Add IN's
Business Add-Ins are SAP enhancement technique based on ABAP Objects.
Where the SAP standard program is not going to fullfill the client requirement , we are going to add our own program to SAP standard program, without changing the standard prog.
Each Business Add-In has
at least one Business Add-In definition
a Business Add-In interface
a Business Add-In class that implements the interface
Each BADI has two different Views.
1.Definition view
2.Implementation view
T.C for BADI Definition is SE18.
T.C for BADI Implementation is SE19.
There are multiple ways of searching for BADI.
Finding BADI Using CL_EXITHANDLER=>GET_INSTANCE
Finding BADI Using SQL Trace (TCODE-ST05).
Finding BADI Using Repository Information System (TCODE- SE84).
1. Go to the Transaction, for which we want to find the BADI, take the example of Transaction VD02. Click on System->Status. Double click on the program name. Once inside the program search for CL_EXITHANDLER=>GET_INSTANCE.
Make sure the radio button In main program is checked. A list of all the programs with call to the BADIs will be listed.
The export parameter EXIT_NAME for the method GET_INSTANCE of class CL_EXITHANDLER will have the user exit assigned to it. The changing parameter INSTANCE will have the interface assigned to it. Double click on the method to enter the source code.Definition of Instance would give you the Interface name.
2. Start transaction ST05 (Performance Analysis).
Set flag field "Buffer trace"
Remark: We need to trace also the buffer calls, because BADI database tables are buffered. (Especially view V_EXT_IMP and V_EXT_ACT)
Push the button "Activate Trace". Start transaction VA02 in a new GUI session. Go back to the Performance trace session.
Push the button "Deactivate Trace".
Push the button "Display Trace".
The popup screen "Set Restrictions for Displaying Trace" appears.
Now, filter the trace on Objects:
V_EXT_IMP
V_EXT_ACT
Push button "Multiple selections" button behind field Objects
Fill: V_EXT_IMP and V_EXT_ACT
All the interface class names of view V_EXT_IMP start with IF_EX_. This is the standard SAP prefix for BADI class interfaces. The BADI name is after the IF_EX_.
So the BADI name of IF_EX_CUSTOMER_ADD_DATA is CUSTOMER_ADD_DATA
3. Go to Maintain Transaction (TCODE- SE93).
Enter the Transaction VD02 for which you want to find BADI.
Click on the Display push buttons.
Get the Package Name. (Package VS in this case)
Go to TCode: SE84->Enhancements->Business Add-inns->Definition
Enter the Package Name and Execute.
Here you get a list of all the Enhancement BADIs for the given package MB.

Seeking simple example pl/sql to create text file from table data

hello,
I am hoping someone can provide very simple example of creating a file on my local harddrive using a pl/sql program. The basic steps are as follows:
First, I store some text in a varchar2 variable like this:
1. select sometext into otextvar from mytable where recordid = 1;
Second, I want this text to become a file in my data directory:
2. c:\data\sometext.txt
The second step is where I need help.
Any suggestions are greatly appreciated.

Use this function
It will create for you a file in your /home/oracle directory with sysdate name and will insert all table names in it
CREATE OR REPLACE PROCEDURE my_proc AS
CURSOR cursor1 IS
SELECT table_name from all_tables;
CURSOR cursor2 IS
SELECT sysdate from dual;
rec1 cursor1%ROWTYPE;
rec2 cursor2%ROWTYPE;
created_file_name VARCHAR2(100);
file_name utl_file.file_type;
BEGIN
OPEN cursor2;
LOOP
FETCH cursor2 INTO rec2;
EXIT WHEN cursor2%NOTFOUND;
created_file_name:=rec2.sysdate;
file_name := utl_file.fopen('/home/oracle', created_file_name,'W');
OPEN cursor1;
LOOP
FETCH cursor1 INTO rec1;
EXIT WHEN cursor1%NOTFOUND;
utl_file.putf(file_name, '%s\n',rec1.TABLE_NAME);
END LOOP;
utl_file.fclose(file_name);
END LOOP;
END my_proc;
SQL>exec my_proc;

InCopy CS5 Crashes Upon Exit

Hello. I am currently working with InCopy CS5 and have an issue with the software crashing when exiting the app. This error reads:

This ONLY happens when working with files on a network share (eiter UNC or mapped drive letter). Copying the same files locally (c:\temp for example) works just fine. Not knowing much about CS5, I obtained the files the tester was working with. There are two fonts missing from the story / project that get replaced with the default font, and it was created with CS3. Wouldn't suspect corrupt files if working with them locally doesn't have the problem...
For installation, first is the base code from the CS5 disk followed by updates including Bridge 4.0.3, InCopy 7.0.3, Player for Embedding 3.1, Extended Script Toolkit 3.5.1, CS Live Services Update for CS5, and Photoshop Camera Raw 6.2. All Adobe products are up to date according to the Adobe Applicaiton Manager. Yes, the workstations have been rebooted.
I don't see anything related in the support forums or through a google search. Looking for assistance troubleshooting / resolving. Thanks in advance.

That is a sign that your preference files are becoming corrupt. Something is wrong with your system if this is happening regularly.

Trying to create a simple example. Need Help!

I'm trying to create a very simlpe examlpe using Swing components to illustrate a MVC architecture.
I have a JFrame containing a JTree and a JButton.
What I'd like to happen is when I click the JButton the JTree model is changed in some fashion and the the view is refreshed due to the models change.
If anyone out there has a simple example of any MVC architecture involving Swing components I'd love to see it.
Thx

Sure, look at any of the Sun tutorials. For example, look in your API documentation for JTree; it has a link to a tutorial about how to use JTree.

Is there a simple example, I can see how to connect to a db using Flash 8 and actionscript? (not with components)

I have been looking all over for a simple "hello world"
example, on how to connect to a database, and pass a param, and
return a dataset. I would like one that does not use components.
(Actionscript only). That uses ColdFusion 7.x and Flash 8. Can
anyone point me to one?

Thanks Craig, I saw that example, but it was meant for Flash
MX, and according to the Flash 8 documentation, the NetServices is
now deprecated. Anyway, I posted my question on another site and
some supplied me with a simple example. Here is the url if anyone
is interested...

Looking for a simple example of the Minimax algorithm in java

Hey everyone,
I'm currently working on a Gameboy emulator program as a pet project, and for one of the game's I'd like for the enemy AI to use the Minimax algorithm, but I don't have any experience with it (or recursion in general, for that matter). Could anyone maybe post a simple example of how this algorithm works?

WTF? I'm sure you can find plenty of examples on google. It's on you to take the time to go through them, study them, and, if you still don't understand something, post a clear, concrete question that indicates what you read and what you didn't understand about it.
As is, you're essentially treating folks here as your research flunkies and saying, "Give me an example that's better than all the ones already easily available to me. Read my mind to know why I didn't like them."

Photoshop CS3 Extended Crash on exit

Problem with AdobeOwl.dll according to debug report. Also Variations not working. I can send jpg of crash report if you like.

My CS3 Extended has just started to exhibit this crash on exit error: "This application has encountered an error and needs to close". It ran perfectly until about 1 week ago and I am wondering if it has anything to do with the latest Windows XP update to the Microsoft.NET Framework 3 as this is the only update I ran after returning from a weeks holiday.

I need some simple examples to start with for Oracle ESB

Hi All,
Please share some simple examples to startwith for Oracle ESB.
I need to understand, what are the files are created, once created an ESB project.
What is the use of the files how to edit them with out using JDeveloper.
Iam trying to create a simple example.
I would like to create a file which has only "HELLO" in that file, simple text file inside a folder "INPUT" in my c:\ drive.
I wanted to create a ESB service which picks up the file and add a string to it like "HELLO" + "ESB" and drop this file into "OUTPUT" folder in c:\ drive.
How do i do that. I tried to do it when i deploy the integration server connection is gettting hit badly. I dont see that connection any more and i dont see that connection in my JDeveloper.
I dont want to start with existing code.
Please help
Regards,
Vijay.B

Hi,
If you want to do it from scratch you can basically do the following:
Make sure you have created an application server and integration server connection in JDeveloper.
1) Create a new JDeveloper project of type ESB project.
2) Possibly add a ESB System/Group (open the esb file and click "Create System/Group") to group ESB projects.
3) Create an XML schema describing your input XML file. Probably one element of type xsd:string.
4) Create an example XML file which is well-formed and valid according to the XSD from step 3.
5) Create a new File adapter (inbound/read). A routing service is automatically created.
6) Create a new File adapter (outbound/write).
7) Create a routing rule in the routing service in which you invoke the write method of the outbound file adapter. Possibly add a transformation using the XSL mapper.
8) Deploy the ESB project to the server.
9) Drop your XML file (from step 4) in the directory in which the inbound file adapter is polling.
10) If it is ok, the file should be picked up, transformed and dropped in the outbound directory. A new ESB instance should be visible in the ESB console.
See what files are generated on the filesystem in each of the above steps.

RCP application on Windows JVM 1.6.0_12 crashed with exit code = 1073807364

A user was using my RCP-based application over several days. At one point, when he apparently wasn't actively using it, the JVM crashed with exit code 1073807364. After some research, I haven't been able to determine what this exit code refers to.
On additional, possibly helpful bit of information is that the hex equivalent 0x40010004 is used to indicate Windows task status. However, this app is not running Windows tasks that I know of, although perhaps RCP, SWT or the SQL Server JDBC layer is doing so without my knowledge.
Can anyone tell me what this exit code indicates, or how to find out?

Taskkill /F broken in windows 8 when applied to a process that crashes on exiting

It appears that Windows 8 has broken the taskkill command in part at least (actually, I think it is more likely a broken ability to set the debug attribute, which in prior Windows versions allowed taskkill to kill programs even if in a different security
context; but I don't know exactly how to test that or prove my hypothesis). When attempting to kill a process that is hung on exit (e.g., attempted a normal exit from the program, but it hangs and fails to exit, and continues to consume system resources),
there appears to be no way to terminate the application/service, and an "access denied" error is generated even though run from the administrator command prompt.
I have had this happen now many times with chrome.exe (which seems to have lots of issues with Windows 8 in general, but especially when exiting), as well as Skype.exe (a perpetual problem child program under any system). It is repeatable if you can
get any program to crash/hang on exit:
(1) start a bunch of chrome.exe windows, especially ones that require resources like scripts, and then attempt to exit chrome window by window - this will cause chrome to crash on exit 5/10 times. Confirm hung process via ctr-shift-esc and see
that at least one chrome task is still running (chrome window may or may not still be visible)
(2) From the administrator command line: "taskkill /IM chrome /F" which will give the access denied error.
(3) psutils is also unsuccessful: pskill chrome /F also gives same error (run from administrator command prompt)
As I understand prior Windows releases, there is a debug attribute that was set by these particular utilities (under Windows 7 and earlier) which allowed taskkill and pskill to kill processes even when the task manager failed to do so. It seems
that something is broken under Windows 8 now in that regard.
Any ideas how to fix? is there a registry fix? Another utility that works under Windows 8?

Hi,
I tried the command in Windows 8, it works with no problem. I can even kill explorer.

The problem is with killing certain "runaway" processes. I can kill chrome just fine ... until it crashes! Once it crashes, it is unkillable. Something is not right.

Can't get "Simple Example Doclet" to run -- Cannot find

I am trying to run the "Simple Example Doclet" at http://java.sun.com/j2se/1.3/docs/tooldocs/javadoc/overview.html.
It appears to compile ok, but when I go to run it I get the message "javadoc: Cannot find doclet class ListClass".
Listed below is:
     1. The execution command and error message
     2. The version (output of javadoc -J-version)
     3. The javac compile command and input and output files
All directories have been kept the same as in the example.
Any help would be appreciated.
Thanks
1. C:\jdk1.3>javadoc -doclet ListClass -classpath C:\jdk1.3\lib\tools.jar MyClass.java
javadoc: Cannot find doclet class ListClass
1 error
2. javadoc -J-version
     gives
          java version "1.3.1_01"
          Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1_01)
          Java HotSpot(TM) Client VM (build 1.3.1_01, mixed mode).
3. javac -classpath C:\jdk1.3\lib\tools.jar ListClass.java
     appears to give good compile ....
          e. g. Input source file ListClass.java is as follows:
               import com.sun.javadoc.*;
               public class ListClass {
               public static boolean start(RootDoc root) {
               ClassDoc[] classes = root.classes();
               for (int i = 0; i < classes.length; ++i) {
               System.out.println(classes);
               return true;
          and.....
          decompiled ListClass.class file is as follows:
               // Decompiled by DJ v2.8.8.54 Copyright 2000 Atanas Neshkov Date: 10/11/2001 4:09:46 PM

               // Decompiler options: packimports(3)
               // Source File Name: ListClass.java
               import com.sun.javadoc.RootDoc;
               import java.io.PrintStream;
               public class ListClass
               public ListClass()
               public static boolean start(RootDoc rootdoc)
               com.sun.javadoc.ClassDoc aclassdoc[] = rootdoc.classes();
               for(int i = 0; i < aclassdoc.length; i++)
               System.out.println(aclassdoc[i]);
               return true;

Sorry to be so late in getting back to you .. I was on vacation.
ListClass is in the current directory. I did get it to work however... In order to get it to work I had to do two things:
1. use -docletpath (even thought it was in the current path) e. g. -docletpath C:\jdk1.3\ListClass.jar
AND
2. Make the class file a jar file -- I could not get it to work otherwise.
p.s. the typo was a decompiler error.

Need help with a very simple example. Trying to reference a value

Im very new to Sql Load and have created this very simple example of what I need to do.
I just want to reference the ID column from one table to be inserted into another table as DEV_ID.
Below are my: 1) Control File, 2) Datafile, 3) Table Description, 4) Table Description
1) CONTROL FILE:
LOAD DATA
INFILE 'test.dat'
APPEND
INTO TABLE p_ports

hi,
i managed to do this for my app. (think i referred to viewTransitions sample code and modified quite a bit)
i can't remember this well cos i did this quite a while back, but i will try to help as much as possible
1) from the appdelegate i initialize a root controller (view controller class)
2) this root controller actually contains two other view controllers, let's call it viewAController and viewBController, for the screens which u are going to toggle in between. and there's also a function, let's call it toggleMenu, which will set the menus to and fro. i copied this whole chunk from the sample code. it actually defines the code on what to do, i.e. if current view is A switch to B and vice versa.
3) inside the controller files, you need to implement the toggleMenu function too, which basically calls the rootController's toggleMenu
4) we also need viewA and viewB files(view class)
5) need to add the .xib files for the respective views and link them up to the controller class. i did not use the .xib files for ui layout though, because of my app's needs. however, it will not work properly without the .xib files.
5) inside the view class of both views, i.e. viewA.m and viewB.m, you need to create a button, that will call the toggleMenu function inside the respective controller class.
it will look something like this:
[Button addTarget:ViewAController action:@selector(toggleMenu:) forControlEvents:UIControlEventTouchUpInside];
so the flow is really button (in view)-> toggleMenu(viewController) -> toggleMenu(rootController)
i'm sorry it sounds pretty hazy, i did this part weeks before and can't really remember. i hope it helps.
