OOPS concept in Labview thru GOOP

hi
actually we are tryng to implement OOP's concept in Labview thru GOOP.
while implementing the above concepts these are the steps we followed.,
1)First we created class A having int i variable with get and set methods.
2)In new vi let it be main.vi we instantiating the class A and setting the varialbe i thru setI method.
3)Finally we are storing the reference in a Global variable.
4)In another main2.vi,we are calling the refernce from the global variable,and trying to call getI method in class A.
5)we are getting the refernce with i value for the first time, and for the rest of the time the value of i is zero.
could anybody help us out.

Rajus,
Usually, you can think of refnums as a "pointers" to a reference and when stored in global variable, LabVIEW may update the reference without updating the global thus explaining the fact that you get a zero value the rest of the time.

OOPS concept

Hi,
What is the use of OOP's concept in oracle data base .
and in what scnario it is use full????
Thanks in Advanced

Not a lot of people use Objects in the database. It is hard to tell whether this is because Oracle's object implementation lacks some crucial OO features. Or is it just that database programmers don't understand OO principles or see no advantage in an object approach.
I wrote a couple of articles on this topic last year in my blog. In part one I discuss the incompleteness of Oracle's OO implementation. In part two I attempt to describe the sort of scenario where an OO approach offers benefits over PL/SQL packages.

How to make a row as selected in output internal table in oops ALV

Hi All,
I have ALV grid output using oops ALV concept, in my output i have a checkbox as first column when i select this checkbox and press a push button 'Print' which is there above ALV grid that particular line in output table should get selected and i need to code some logic for printing selected row.
how to make the particluar row in the output internal table to be selected and where to write the logic for print once it is pressed?
Thanks in advance
Srilakshmi.

but the checkbox is not getting set in internal table when i select some checkboxes.
can anybody explain y the checkbox in internal table not set?
Hi Srilakshmi,
As explained by Uwe, when we change a field ( say check box ) in ALV grid, the view (frontend) changes (showing the tick mark) but the changed data ( normally ) is not transfered to the backend.
We can initiate this data transfer by just registering the cl_gui_alv_grid=>mc_evt_modified edit event
go_grid->set_table_for_first_display( CHANGING it_fieldcatalog      = pt_fieldcat
                                                  it_outtab            = pt_outtab ).
go_grid->set_ready_for_input( 1 ).
go_grid->register_edit_event( EXPORTING i_event_id = cl_gui_alv_grid=>mc_evt_modified ). " This does the trick
Now as soon as we check a checkbox, the data_changed event is triggered.
This initiates data transfer to the backend and the checkbox field in internal table is updated.
check the below code for example.
DATA: go_cont            TYPE REF TO cl_gui_custom_container,
      go_grid            TYPE REF TO cl_gui_alv_grid,

OOP's ALV : Download to excel issue

Hi All,
I am using oops ALV in a report .
I need to implement it in such a way that when user export the list to excel
1. Downloaded excel should also contain the data printed in top- of-page followed by the grid data.
i.e some desired records followed by the main records.
I am able to display the output data as desired, But when I download data to excel, it gives only records
from grid and not the top-of-page data.
Please let me know how to solve this ?
Do I need to change approach?
Thanks in Advance.

Hi,
To display the top of page in ALV FM we use the TOP_OF_PAGE event to display the data. But in Oop's Concept if you populate the data in TOP_OF_PAGE event the data will not be displayed in ALV layout but when print preview or print then you can see the TOP_OF_PAGE data.
So to show the data on the ALV layout we use the split conatainer concept. Split the container in two and display ALV in below container and TOP_OF_PAGE in top container.
Apart from having above you still populate the TOP_OF_PAGE event of ALV. This will be come into picture in case of download,Print priview & Print.

Problem in OOP ALV-ALV not displaying.

Hi Gurus,
Can we use OOP alv concept in normal executable program or we need to do it in module pool ?
I did an example alv program..but it is not exectuing .
Can anybody tell me the answer ?
Thanks.

Hello,
To use OO ALV you need to create a container in module pool. But you can still call it from an executable program. Just create an executable program and use call screen 0100. Now double click on 0100 and create a screen which has a container on it then in the PBO module just caal the methods for the custom container and alv. Upon execution of the program, the alv will be displayed.

Sachin

Multiple selection in alv

how to select multiple values in the generated output list for futher selection criteria in alv's without using oop's concept
basically using " reuse_alv_grid_display" function module

Hi
First, are you using the function module 'REUSE_ALV_GRID_DISPLAY'.
If so, MAYBE u can try this.
1. In the internal table for displaying in ALV, u can add a field
say 'SELK'.
2. In the ST_LAYOUT, you assign the name of this field to the field
"BOX_FIELDNAME" in ST_LAYOUT structure.
FORM layout_build USING p_st_layout TYPE slis_layout_alv.
p_st_layout-box_fieldname = 'SELK'. " Checkbox
ENDFORM. " LAYOUT_BUILD
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
EXPORTING
is_layout = st_layout
IMPORTING
E_EXIT_CAUSED_BY_CALLER* ES_EXIT_CAUSED_BY_USER TABLES
t_outtab = itab.

Is java 100% pure object oriented?

I am very confuse is java 100% pure object oriented language.
bcoz
1)object oriented means everything should be in object but
primitive data type is not object.
2) java don't support multiple inheritances which is one of the oop 's
concept

I'd say that java is 100% java. No more, noless.
I'm gonna say it's about 99.4738383% java. For
no
reason other than to confuse idiotsSomeone's always bumping their heads against
some
arbitrary theoretical purity when they aremissing
what was, is and always has been most important:
functionality.Functionality matters virtually nothing to thepeople
that post these "questions". All that matters is
being able to say the right thing in interviews so
they can get a job and get carried through their
career by people who actually know what they're
doing. See it all the timeHehe, who carries you whilst you post here all day

ALV Print Options

Hi,
I have a report program, made using oops ALV concept. The requirement is such that if the report output displays 10 rows, and if you select 5 rows and say PRINT then only those selected 5 rows should be printed.
In the standard print functionality this is not possible. Could you please suggest an appropriate work-around for this issue?
Thanks in Advance,
Shivali

Hi Shivali,
As an alternative you may define a USER COMMAND event .
Create a button on toolbar, which perform the print operation for those selected rows.
Something like this -
FORM user_command USING u_ucomm TYPE syucomm
us_selfield TYPE slis_selfield. "#EC CALLED
CASE u_ucomm.
WHEN 'PRINT'.
*Call the print operation
ENDCASE.
ENDFORM.

Why standard programs uses the OCCURS statement

Hi Experts,
instead of occurs we usually use STANDARD TABLE OF due to performance issue ,
but i noticed that stadard programs are using OCCURS statement only.
could u plz tell me why stadard programs are using OCCURS only.
Thanks.

Hi,
Occurs Statement created the internal table with header line. But Header Line is not supported in Oop's Concept. So it is better practice to create the table with TYPE/LIKE STANDARD TABLE OF statement without specifying Header line option in declaration.
Yes in most of the standard Programs OCCURS statement are used. This is because these are SAP standard and developed in older version of sap.
