[http://sapabapnotes.blogspot.com/]
I do same steps as given in this link....but it show some syntax error when i check it...
Error : "IT_LFA1" is not an internal table - the "OCCURS n" specification is missing...

Handle events in global class

Hi all,
I am working on handling events in global classes.
but my event is not triggererd,i m not able to find where it's going wrong.
Below is my code.
Global Class:ZCL_TEST_EVENT
events :EXCEEDEDRANGE
methods:CHECKRANGE,DISPLAYVENDOR.
Checkrange is event handler for exceededrange.
below is the code for methods.
method checkrange.
write:/ 'Vendor not within the range'(001).
exit.
endmethod.
method displayvendor.
DATA : exlfa1 TYPE lfa1.
IF imlifnr NOT BETWEEN 1000 AND 2000.
    RAISE EVENT exceededrange.
ENDIF.
SELECT SINGLE * FROM lfa1
       INTO exlfa1
    WHERE lifnr = imlifnr
IF sy-subrc = 0.
    WRITE : / exlfa1-lifnr,exlfa1-name1.
ELSE.
    WRITE : / 'No vendor found'(002).
ENDIF.
endmethod.
below is the report I developed.
REPORT ztest_113.
parameters :plifnr type lfa1-lifnr obligatory.
data : obj type ref to ZCL_TEST_EVENT.
START-OF-SELECTION.
CREATE OBJECT obj.
CALL METHOD obj->displayvendor
EXPORTING
    imlifnr = plifnr
Please help

Yes, you do need to write the SET HANDLER statement. As per your current design, you can set the event handler in your method CONSTRUCTOR. Like:
method constructor.
SET HANDLER me->CHECKRANGE FOR me.
endmethod.

Create Events in derived class of CNi4882Device

Using VB and CW GPIB ActiveX control, we are able to do this:
CWGPIB1.NotifyMask = cwGPIBRQS
CWGPIB1.Notify
Private Sub CWGPIB1_OnGPIBNotify(ByVal mask As Integer)
In VC++, i have created a derived class from CNi4882Device. How do I add event capabilities to it and get the same callback mechanism as in the VB example?

You will use the InstallEventHandler function. You can use it to install an event for any event mask that you want. Then you can just override the OnEvent virtual member of the class and handle the event however you like. You can also install an external (outside the class) function to handle the event, but since you are deriving from CNi4882Device, it would make more sense to override the virtual member OnEvent. See the online help for CNi4882::InstallEventHandler and CNi4882:nEvent for more help.

Calling Instance Method in a Global Class

Hi All,
Please can you tell me how to call a instance method created in a global class in different program.
This is the code which I have written,
data: g_cl type ref to <global class>.
call method g_cl -> <method name>
I am not able to create Create object <object>.
It is throwing the error message " Instance class cannot be called outside...."
Please can anybody help me..
*Text deleted by moderator*
Thanks
Sushmitha

Hi susmitha,
1.
data: g_cl type ref to <global class>.
2.
Create object <object>.
3.
call method g_cl -> <method name>.
if still you are getting error.
then first check that method level and visibility in se24.
1.if level is static you can not call it threw object.
2. if visibility is protected or private then you can not call it directly.
If still you are facing same problem please paste the in this thread so that i can help you better.
Regards.

Global class event handler not called

I am having a problem where I created a function module that instatiates an application log class. This application log class has methods ON_* for public events of other classes.
The function module then processes its routines and as a result some of these events are raised. Ex: The function module creates a Purchase order and in that class I have a public even PO_CREATED that is raised upon succesfull creation of the PO. The global class APPLICATION_LOG I created has a method ON_PO_CREATED for event PO_CREATED of class ZCL_MAT_PO.
I put a break point in the APPLICATION LOG method but is os not called.
ANy idea of what Iam doing wrong or missing?
Thanks,
Leo

Hi Leo, did you set the handler method?
SET HANDLER <method_name> FOR <object>.

Create Global Class Definition using Local Class Source Code

I would like to be able to automate the creation of global class definitions using source code that is defined in a text file (one example: convert a local class def to a global class def).
Does SAP deliver this functionality? (I'm already aware of the various classes that can be used to create global classes and how those classes can be implemented in a program to generate new classes. I'm hoping to avoid having to create a custom solution.)
Thanks in advance!

We have a winner!
Thanks Rich!
It's not a 100% solution - I was hoping to be able to generate global classes/interfaces using source code alone, without requiring user intervention.
It is however, a 90-95% solution because debugging SE24 reveals that by using a combination of the FM's SCAN_ABAP_OBJECTS_CLASSES & SEO_CLIF_MULTI_IMPORT, I should be able to quickly put together that custom application that I was trying to avoid.
I knew about the existance of SEO_CLIF_MULTI_IMPORT but I did not know about SCAN_ABAP_OBJECTS_CLASSES. I'm very happy to learn that I'm not going to have to write a parser!

How to use global classes and display returned data?

Hello experts,
I have the following code in a program which accesses a global class (found in the class library). It executes one it's static methods. What I would like to do is to get hold of some elements of the returned data. How do I do that please?
Your help is greatly appreciated.

Here are the errors I get:
The field "DREF" is unknown, but there is a field with the similar name "OREF" . . . .
When I replace itr by OREF I get:
"OREF" is not a data reference variable.
I then try to change it to dref_tab. I get:
"DREF_TAB" is not a data reference variable.
Any idea? By the way, must there be a HANDLE event for this to work?
Thanks for your help.

Global classes / Doppelclick

Hello Every Body,
please can someone tell me how can implement Doppelclick using Global classes.!!
Best regards.
daniel

Hello Daniel
I assume you want to handle DOUBLE_CLICK events of controls (e.g. ALV grid, tree) using global classes.
That's a piece of cake. Below I outline a possible procedure:
(1) Create your control instance (e.g. go_grid, CL_GUI_ALV_GRID)
(2) Create an instance of your global class. The CONSTRUCTOR method may look like this:
CREATE OBJECT go_myclass
EXPORTING
io_instance = go_grid. " Assumption: class should only handle ALV grid events
METHOD constructor.
me->mo_grid = io_instance. " class may have instance attribute for grid instance
me->set_handler( ). " perhaps private method for setting event handler
ENDMETHOD.
METHOD set_handler.
SET HANDLER: handle_double_click FOR me->mo_grid.
ENDMETHOD.
(3) Create an event handler method (e.g. HANDLE_DOUBLE_CLICK for event DOUBLE_CLICK of cl_gui_alv_grid) within your global class.
That's it. As soon as the user double-clicks on a row in the ALV grid (go_grid) the method HANDLE_DOUBLE_CLICK of your global class will be called to handle the event.
Regards
Uwe

Help me I'm trying to create event listeners

I am trying to create event listeners
Whenever any keyboard event occurs the string s gets appended by a,c
or p.At the end of the program its supposed to print value of s
But s always happens to null.Please tell me how to correct it....so
that detection is possible for any case
import java.io.*;
import java.awt.event.*;
public class trial {
int x;
public static String s;
//OutputStream f1=new FileOutputStream("file2.txt");
public static void keyReleased(KeyEvent e)
s=s+"a";
public static void keyPressed(KeyEvent e)
s=s+"c";
public static void keyTyped(KeyEvent e)
s=s+"p";
public static void main(String args[])
throws IOException
char c;
BufferedReader br =new BufferedReader(new
InputStreamReader(System.in));
System.out.println("Entercharactes,'q' to quit.");
do
c=(char)br.read();
System.out.println(c);
while(c!='q');
// for(int i=0;i<s.length();++i)
System.out.println(s);

I suggest looking at the java tutorial. Your code completely misses the mark and you need to see examples.

View not copied or enhanced with wizard Error while creating Event Handler method in Z Component

Hello Friends,
In one Z Component (Custom Component), in one of the views, while creating event handler, it gave me error message that view not copied or enhanced with wizard.
I am aware that in Standard Component, if we want to create the event handler method then we need to first Enhance the Component and then we need to enhance the view.
But, in the Z Component (Custom Component), how to create event handler method in one of the views as while creating event handler method i am getting view not copied or enhanced with wizard error.

Hi,
Add a method in views impl class with naming convention eh_on__* with htmt and html_ex parameters. I dont have have the system right now. Please check any existing event import export parameters.
Check out do handle event method in the same class.
Redefine that method. Call that event method in this handle method. See existing code for reference.
Attach that event to the button on click event in .htm page.

Bhushan

Creation of Material using BDC Session method & global class

Hi
Creation of Material using BDC Session method & global class by using oops.
can anyone plz help me out

Hi,
it looks like it's not possible to call this BAPI wihtout material number. Here is a quote from BAPI documentation.
When creating material master data, you must transfer the material
number, the material type, and the industry sector to the method. You
must also enter a material description and its language.
Cheers
