GetObject in ABAP language

[stefan_schnell]

Hello community,

to create a new COM object I use the command CREATE OBJECT in ABAP. Is it possible to use an existing COM object on the presentation server? Other programming languages offers the command GET OBJECT to return a reference to an existing object. Is there an equivalent in ABAP?

Thanks for hints and tips.

Cheers

Stefan

No there is not. If you are going to write a Z class you can achieve the same functionality by using the Singleton pattern ([http://en.wikipedia.org/wiki/Singleton_pattern]). In ABAP you can achieve more or less like this:

CLASS lcl_test DEFINITION   CREATE PROTECTED .

  PUBLIC SECTION.
    CLASS-METHODS get_instance
     RETURNING
       value(re_instance) TYPE REF TO lcl_test.

  PROTECTED SECTION.
    CLASS-DATA: my_instance TYPE REF TO lcl_test.
ENDCLASS.                    "lcl_test DEFINITION

CLASS lcl_test IMPLEMENTATION.
  METHOD get_instance.
    IF my_instance IS NOT BOUND.
      CREATE OBJECT my_instance.
    ENDIF.
    re_instance = my_instance.
  ENDMETHOD.                    "get_instance
ENDCLASS.                    "lcl_test IMPLEMENTATION

If you mean using OLE, yes there is such a way in ABAP. Search for term +CREATE OBJECT ole + .

Also nice references how to import various controls from outside SAP [Using .Net Windows Controls in the ABAP Control Framework|http://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/754] [original link is broken] [original link is broken] [original link is broken] [original link is broken]; and [Using Classic ActiveX Controls in the ABAP Control Framework|http://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/995] [original link is broken] [original link is broken] [original link is broken] [original link is broken];
