GUI Programming with ABAP - Chapter 9

I am working my way through the ABAP Objects (Keller/Krueger) book, doing all the exercises, re-entering all the programs for learning purposes. I get to Chapter 9, and the package I am working with has moved form Z_ABAP_BOOK to SABAPDEMOS. There are examples there, but when I try to edit any of them, I get a "Register Object" dialog box, asking me for an Access Key for the Demosystem installation. Where do I find this key? Is this the SAP License key, or something else?

Marcelo,
Copy the program. Of course. I really appreciate someone trying to answer the question, and since you started, I hope you can help me until it is finished.
Now, how exactly do I do that? Copy the program? And when I say 'exactly', I really, really mean specific. Because, the only work I have ever done with SAP/ABAP is with the book and the downloaded software. I have not worked with different 'packages'.
Please, step by step. Baby steps.
Here's what I tried and what doesn't work. I tried to right-click the program DEMO_DYNPRO in the SABAPDEMOS package. One of the options is 'Copy'. That brings up a dialog box, but looks as if it only copies the program within the same package. If I try to go further, by making a unique 'to' program name, it asks me for the access key. Same as my first problem.
If I rightclick on the DEMO_DYNPRO program and go down to the 'Other Functions', there is 'Change Package Assignment' option. This sounds hopeful, so I tried it. I get a dialog box that says 'Reassign Object DEMO_DYNPRO'. in the New Package field, I choose Z_ABAP_BOOK. The error I get is 'Package in non-original system only modifiable with Organizer tools'.
I pull up the Long Text, and it tells me to use the Transport Organizer Tools. Lucky for me, that message can be clicked and it actually OPENS the Transport Organizer Tools. The message in the long text tells me to looks SPECIFICALLY for 'Change object directory entries of objects'. There is no option with that SPECIFIC title.
There is a 'Change Object Directory Entries' and a 'Change Object Directory Entries of Objects IN A REQUEST'.
I tried the first one. In the next screen that appears, I put DEMO_DYNPRO in the Program field, and put SABAPDEMOS both FROM and TO under Further Restrictions / Package and pressed F8 (execute). This shows the entries in the SABAPDEMOS Package. I can find the DEMO_DYNPRO in the list, and I can use the little icon that says Select/Deselect. This highlights the program I want in yellow. Looking around, I was able to find under the Objects Menu, there is an option to Change Object Directory Entry. I change the Package to say Z_ABAP_BOOK and the Person Responsible to say BCUSER. I press the save icon and the error I get is 'SAP object Prog DEMO_DYNPRO cannot be assigned to package Z_ABAP_BOOK.
So, am I going about this totally incorrectly? Or am I close? Please tell me exactly what to do.

Hello everyone
Now i want to learn ABAP OO,and Lots' of guys told me that the book Object-Oriented Programming with ABAP Objects is realy a good book.but i searched on the net,and could not got PDF of this book,could some one gave me the net address if you know where to download the book or send me to my Mailbox:<email id removed by moderator>,I will very glad to receive any response from you,
of course,if you have some advise on how to learn ABAP OO or some other material ,hope you could share your meaning with me, hope to receive your response.

Running a GUI program with no X?

Hi,
I want to run a GUI program on my server, which has no X installed. Of course, the program would normally not run since it needs X (GUI only). I don't really need to be directly using this software, it just needs to run. Anybody here knows if there is any way to fool it into thinking X is there, so it'll still run on my server, preferably as a service in the background?
PS
I probably need the same thing for sound too, no alsa or pulse either.
Any help's appriciated.

I probably owe you guys an explanetion: The program in question is Skype. I'm sick and tierd of having skype steal recources when all my other IMing is done in bitlbee. That's why I came up with the following solution: I've done some reading, and turns out skype has a bitlbee plugin.
However, that plugin uses the skype API which means I can't get around having skype. So, I decided to try the following setup: Run a bitlbee server from my home server. Have skype sorta just run in there doing nothing, and use the bitlebee plugin so I can connect with my own computer and use skype with bitlbee (Note: this is so I can chat with friends, not so I can video / audio chat so I don't care about those features). Basicly that was my idea and i'm exploring the posibility. Skype sadly has no deamon mode, but it does offer a shell pipe login so I'll start skype in my server, and do that setup. Of course now that I see i'll need to install x no matter what i'm not sure if it's worth it. I don't need X on my server for any other purpuse and X will steal recources from my server. I do however love not needing a skype client nativly. Anyone has any experiance / ideas / advice about my idea?

Wut? You want to output sound without anything that is able to output sound? Is it me or is that just plain weird....? o.O
I realize it sounds comfusing but Skype needs somewhere to dump sound apperantly (I found that out on my resharch). So I need a way to fool it into thinking there's such a device.

Module pool programming with Abap Objects

Hi masters,
Somebody tell me that you can directly call a local class in a module pool.
Is that possible?
Can anybody refer me to any kind of information?
Thanks a lot.

Well, thanks for the answer, but not was the one i was waiting for... it wasn't helpful.
But, i've continued searching for answers... and i've found that:
OO Transactions Locate the document in its SAP Library structure
In transaction maintenance (SE93), you can specify a transaction code as an OO transaction.
You either link the transaction code to the Transaction Service of the Structure link ABAP Object Services for persistent objects or to a public method of a global or local class of a program. When calling up a transaction that is linked to an instance method, the system automatically generates an instance of the class in its own internal session.
An example of a link between a transaction code and an instance method of a local class of an unspecified ABAP program:
Example
*& Modulpool DEMO_OO_TRANSACTION *
program DEMO_OO_TRANSACTION.
class DEMO_CLASS definition.
public section.
methods INSTANCE_METHOD.
endclass.
class DEMO_CLASS implementation.
method INSTANCE_METHOD.
message 'Instance method in local class' type 'I'.
endmethod.
endclass.
The DEMO_OO_TRANSACTION program is a module pool of type M that does not contain any screens or dialog modules. Instead, the program contains the definition of a local class DEMO_CLASS.
The DEMO_OO_METHOD transaction code is linked to this program as follows:
The start object of the transaction is Method of a class (OO transaction).
OO transaction model is not selected.
The Class Name is DEMO_CLASS.
The Method is INSTANCE_METHOD.
Local in program is selected and DEMO_OO_TRANSACTION specified.
When the transaction is called up, the program is loaded, an instance of the class is created, and the method is executed.
Leaving content frame
That's what i wanted.
I hope it would be helpful for anyone else.

Trying to compile a GUI program with ActionEvent and Color/Graphics

Hey, I am trying to compile a program that where I press a button it designs/displays a picture. I have the first part that shows the button, but I can''t get the second part of it. Any suggestions on what to do? Here is the part of the code that I am unsure about, the idea is to get that to design a picture:
private class ButtonHandler implements ActionListener
          public void actionPerformed( ActionEvent event )
     }

Heres the code in order to give a better idea of what I am trying to do:
import java.awt.FlowLayout;
import java.awt.Color;
import java.awt.Graphics;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JFrame;
import javax.swing.JButton;
public class Game extends JFrame
     private JLabel greeting; // greets user and gives initial instructions
     private JButton startGame; // start game button
     private JButton highScore; // displays high scores
     private JButton exitGame; // exits game
     // adds buttons to JFrame
     public Game()
          super( "Game" );
          setLayout( new FlowLayout() ); // set frame layout
          greeting = new JLabel( "Make selection..." );
          add( greeting );
          startGame = new JButton( "Start Playing" );
          add( startGame );
          highScore = new JButton( "View High Scores" );
          add( highScore );
          exitGame = new JButton( "Exit Game" );
          add( exitGame );
          ButtonHandler handler = new ButtonHandler();
          startGame.addActionListener( handler );
     private class ButtonHandler implements ActionListener
          public void actionPerformed( ActionEvent event )
          public void paintComponent( Graphics g )
super.paintComponent( g );
g.setColor( Color.RED );
g.fillOval( 10, 10, 200, 200 );

Client-Server side GUI programming

I want to create a client-server side gui programming with java

for information but there are some parts that i didnt understand and wait for your help
i m trying to build an online-help(live chat) system so when people press the start chat button a java page will appear but i wonder how this will connect to the person who is on server side
i mean is it possible to 2 users connect the same port and chat with each other
I mean when user press the chat button the online help supporter will be informed somebody wants to speak with him and they will start a chat
how can i do something like that
any help would be usefull thanks

Below is an example of a client/server program.

import java.util.Random;
* This TriviaServer can handle multiple clientSockets simultaneously
* This is accomplished by:
* - listening for incoming clientSocket request in endless loop
* - spawning a new TriviaServer for each incoming request
* Client connects to server with:
* telnet <ip_address> <port>
* <ip_address> = IP address of server
* <port> = port of server
* In this case the port is 4413 , but server can listen on any port
* If server runs on the same PC as client use IP_addess = localhost
* The server reads file
* Note: a production server needs to handle start, stop and status commands

[KDM] Cannot start gui application with sudo

Hi,
After i had upgraded to kde 4.5, there was a new problem. When i want to start any gui program with sudo (e.g. sudo kwrite) i see that error:
[simas@myhost ~]$ sudo kwrite
No protocol specified
kwrite: cannot connect to X server :0.0
[simas@myhost ~]$
Starting apps like nano works fine. I also discovered that when i use gdm instead of kdm, and boot to same kde desktop, i can start gui apps with sudo fine. when i use kdm no matter if im in gnome or kde starting gui apps from terminal with sudo just doesnt work.
Anyone has any ideas? im starting desktop managers with inittab method.

ABAP GUI programming

Hi,
I'm quite new to programming GUI:s in ABAP so I have a general question for you guys.
What are the best options in terms of ABAP language elements(module pools / reports / ABAP Objects ALV classes) to use for programming low to medium complexity GUI:s in ABAP? A typical scenario is that I need a simple selection screen for the user to make restrictions and then to generate a second screen with a list/table of data to be viewed and maintained by the user, the maintained data will then need to be saved into custom transparent tables when the user presses save - how would you program such a program in general terms?
It is a plus if your proposed approach uses controls that can be translated to webgui.
Any help appreciated,
Regards,
Christian

hi Christian,
As per your requirement, you need to develop a custom REPORT(in SAP terminalogy,we call it as). normally a report consists of a selection screen(where User may enter some Input values) & based on that we will fetch the database tables with the given criteria by the user & get the details & display the result as output(we call report output as LIST). this report we call it as BASIC REPORTS.
if user requires any further functionality after this, we develop INTERACTIVE REPORT, which is nothing but after displaying the LIST(report OUTPUT) user can select/deselect some of the records & requests for further processing.
so in your scenario,
you have to develop
1. a selection screen with the given fields
2. a basic list, with all the details,what user wants
3. take the selected records from the LIST(report Output)
and updating the database.
pl revert, if you need any clarifications

How to create a job thru ABAP program for calling a program with variant???

Hello experts,
can u give me step wise procedure to create jobs for a program with a variant name thru ABAP???
Also, can a transaction can be scheduled as a job to run in background with a variant name???
Edited by: SAP USER on Jul 22, 2008 6:08 AM

Hi,
To create a job through ABAP program you can do the following.
Go to Menu bar.
In there, go to SYTSTEM> SERVICES> JOBS--> DEFINE JOB.
Then give the JOB NAME and CLASS in the screen that comes up.
This is how we schedule a program.
Now, to create a variant for a program -
First activate your program in SE38. Then execute it .
Now, click on SAVE button. It will open up the variant creation screen. Give the details there like variant name and value for the fields. Save and come back.
Hope this helps.

Hari Kiran

Tool creation for checking program of ABAP in TXT format with the ABAP stds

Tool creation for checking program of ABAP in TXT format with the ABAP stds

Hello Jagrut
There is a simple reason why we cannot do off-line ABAP development:
- the ABAP dictionary (which contains all structures, tables, data elementes, etc.)
Because even the simplest ABAP report (except for the "Hello World" report) will reference some objects from the ABAP dictionary and, thus, requires to access these objects directly. Therefore, we are still bound to server-side ABAP development.

Problem with the active version of the transfer rule ABAP program with sour

Hi,
I have a problem with the active version of the transfer rule ABAP program with source system EXCEL.
The system does not react to changes done in the transfer rule coding. For FISCPER I have hardcoded the result 'BABABA' and still the results delivered are those from the CSV.
Resetting the system buffers does not help. The problem is systematic in combination with source system EXCEL (i.e. not only 1 InfoSource). Checking the active program Extras->Display Program shows the coding (result='BABABA') being there, but
as stated, the system does not produce the result BABABA, but instead the result of the CSV.
It seems as if the original version from the very first activation of the transfer rule program remains somewhere and continues to be used. Does anybody know how to flush it out and get the system to actually use the coding appearing as the active program.
I have posted an OSS note, but SAP takes it time to answer and I am under time pressure so I figured that maybe one of you know who to solve it before SAP does.
Greetings and thanks,
Martin

Calling GUI Scripting from ABAP program

Is it possible to call GUI Scripting from ABAP and thus to use GUI Scripting as an alternative to CALL TRANSACTION?
Is the class CL_JAVA_SCRIPT suitable to access GUI Scripting engine? Accessing ABAP data object would work as well in this case as i think. What SAP Logon and WAS releases are required? Is the 6.20 release sufficient for this case?
I would appreciate if somebody could post an example.

Hi,
CL_JAVA_SCRIPT has nothing to do with SAPGUI Scripting.
Calling SAPGUI Scripting API from ABAP could be possible for programmes experienced with OLE automation calls from ABAP coding.
The hardest thing will be, to access the scripting engine handle as an entry point. Once you have a handle in your abap session, any api function can be invoked.
Best regards
Jens
BTW: SAP testtool eCATT does call SAPGUI-Scripting from ABAP.
