How to Run Executable files from WebDynpro ABAP - Part 1

Introduction

This document explains how to run executable files form Web Dynpro ABAP application.

Here I am going to show a small demo on how to run executable files such as .exe files - MSWord, Notepad, Calculator and also .bat files using AcfExecute.

Prerequisites

SAP Netweaver 700 Ehp1.

Step by Step Process

Step 1: Create a Web Dynpro Component.

Go to the SE80 transaction and create a Web Dynpro Component.

Enter Description and click on ok.

Save the Component and Activate it.

Step 2: Data Binding

Go to the Context tab of Main View and create an attribute ERROR of type STRING.

Step 3: Layout Design.

Now Go to Layout tab:

1. Create page header with title ‘ACF Execute Demo’.

Right click on ROOTUIELEMENTCONTAINER, and click on Insert Element.

Enter ID, select UI Element PageHeader and click on OK.

In the properties, enter title.




2. Create a Group UI element - GROUP.

Right click on ROOTUIELEMENTCONTAINER, click on Insert Element and create agroup UI element.




3. Create a Group UI element - GRP1 inside GROUP.

Right click on GROUP UI element and click on Insert Element and create a group UIelement - GRP1.




In the properties, enter text for caption of GRP1 UI element.




4. Create a button UI element - BTN_WORD inside group GRP1.

Right click on GRP1 and click on Insert Element.




Enter ID, select UI element Button and click on OK.





In the Properties of BTN_WORD, enter text of Button.

Create an Action OPEN_WORD for button BTN_WORD.




Similarly create 2 more buttons inside GRP1.

I). BTN_EXCEL with Text "Open MS Excel" and Action OPEN_EXCEL.

II). BTN_PAINT with Text "Open MS Paint" and Action OPEN_PAINT.










6. Create a button UI element - BTN_NOTE inside group GRP2.

Right click on GRP2 and click on Insert Element.




Enter ID, select UI element Button and click on OK.





In the Properties of BTN_NOTE, enter text of Button.

Create an Action OPEN_NOTE for button BTN_NOTE.




Similarly create 1 more button inside GRP2.

I). BTN_CALC with Text "Open Calculator" and Action OPEN_CALC.










8. Create a button UI element - BTN_SHUT inside group GRP3.

Right click on GRP3, click on Insert Element -> Enter ID, select UI element Button andclick on OK.




In the Properties of BTN_SHUT, enter text of Button.




Create an Action SHUTDOWN for button BTN_SHUT.

Similarly create 1 more button inside GRP3.

I). BTN_CANCEL with Text "Cancel Shutdown" and Action CANCEL_SHUTDOWN.

10. Create a button UI element - BTN_LOG inside group GRP4.

Right click on GRP4, click on Insert Element -> Enter ID, select UI element Button andclick on OK.




In the Properties of BTN_LOG, enter text of Button.




Create an Action SHOW_LOG for button BTN_LOG.




11. Create Message Area - MSG_AREA

Right click on ROOTUIELEMENTCONTAINER, and click on Insert Element.




Enter ID, select MessageArea UI and click on OK.





Now our final Layout Looks like this:

Step 4: Attributes Declaration.

Now go to Attributes of MAIN view and create the attributes:

• ACF_METHOD_HANDLER of type ref to CL_WDR_ACFEXECUTE_HNDL and• M_CONTROL of type ref to CL_WD_ACF_EXECUTE.




Step 5: Method Implementation.

Now go to Methods tab and write the below code in WDDOMODIFYVIEW method.

WDDOMODIFYVIEW

METHOD WDDOMODIFYVIEW .

DATA: root_element TYPE REF TO if_wd_view_element,

root_container TYPE REF TO cl_wd_transparent_container.

IF first_time = 'X'.

root_element = view->get_root_element( ).

root_container ?= root_element.

* init GAC control

wd_this->m_control = cl_wd_acf_execute=>new_acf_execute( ).




wd_this->m_control->set_enabled( abap_true ).

wd_this->acf_method_handler ?= wd_this->m_control->_method_handler.

* Create AcfExecute UI

cl_wd_matrix_data=>new_matrix_data( element = wd_this->m_control ).

root_container->add_child( wd_this->m_control ).

ENDIF.

ENDMETHOD.

Now create method a method CALL_ACF_EXECUTE.

Now Double click on CALL_ACF_EXECUTE method and create parameters: APPLICATION and

ARGUMENTLIST of type string.

Write the below code in CALL_ACF_EXECUTE method:

CALL_ACF_EXECUTE

METHOD CALL_ACF_EXECUTE .

DATA: lo_el_context TYPE REF TO if_wd_context_element,

lo_el_context_stru TYPE wdr_ext_attribute_pointer,

lr_acf_exp TYPE REF TO cx_wd_acf_exception,

lv_msg_text TYPE string.



TRY.

lo_el_context = wd_context->get_lead_selection( ).

lo_el_context_stru-attribute_name = 'ERROR'.

lo_el_context_stru-element = lo_el_context.

wd_this->acf_method_handler->if_wd_acfexecute~execute( application = application

argumentlist = argumentlist

errorinformation =lo_el_context_stru ).

CATCH cx_wd_acf_exception INTO lr_acf_exp.

lv_msg_text = lr_acf_exp->if_message~get_text( ).

* get message manager

data lo_api_controller type ref to if_wd_controller.

data lo_message_manager type ref to if_wd_message_manager.

lo_api_controller ?= wd_This->Wd_Get_Api( ).

CALL METHOD lo_api_controller->GET_MESSAGE_MANAGER

RECEIVING

MESSAGE_MANAGER = lo_message_manager.



* report message

CALL METHOD lo_message_manager->REPORT_SUCCESS

EXPORTING

MESSAGE_TEXT = lv_msg_text.

ENDTRY.

ENDMETHOD.

Note: The Application paths which I am specifying in the following methods is inWindows 7 OS which may vary from other Operation Systems. Please use the actualapplication path according to your Operation System.

Double click on ONACTIONOPEN_WORD and write the below code:

ONACTIONOPEN_WORD

METHOD ONACTIONOPEN_WORD.

DATA lv_application TYPE string.

* Set MS WORD application absolute path

lv_application = 'C:\Program Files (x86)\Microsoft Office\Office14\WINWORD.EXE'.

* Call Execute method



wd_this->call_acf_execute( application = lv_application ).

ENDMETHOD.

Double click on ONACTIONOPEN_EXCEL and write the below code:

ONACTIONOPEN_EXCEL

method ONACTIONOPEN_EXCEL .


* Set MS EXCEL application absolute path

lv_application = 'C:\Program Files (x86)\Microsoft Office\Office14\EXCEL.EXE'.



endmethod.

Double click on ONACTIONOPEN_PAINT and write the below code:

ONACTIONOPEN_PAINT

method ONACTIONOPEN_PAINT .


* Set MS PAINT application absolute path

lv_application = 'C:\Windows\System32\mspaint.exe'.





endmethod.

Double click on ONACTIONOPEN_NOTEPAD and write the below code:

ONACTIONOPEN_NOTEPAD

method ONACTIONOPEN_NOTEPAD .


* Set notepad absolute path

lv_application = 'C:\Windows\System32\notepad.exe'.



endmethod.

Now double click on ONACTIONOPEN_CALC and write the below code:

ONACTIONOPEN_CALC

method ONACTIONOPEN_CALC .


* Set Calculator application absolute path

lv_application = 'C:\Windows\System32\calc.exe'.





endmethod.

To Shut Down the system, I have created a batch file. I will run this batch file from WebDynpro ABAP using AcfExecute.

Copy the below code to notepad and save to your local machine with .bat extension ( let sayshutdown.bat ).

SHUTDOWN.BAT

shutdown -s -t 200 -c "Please dont leave me.. I have no one but You.. Bye Kiran.. Will Miss U...Please save YourWork!!"

To Cancel the shutdown, copy the below code to notepad and save to your local machinewith .bat extension ( let say abort_shutdown.bat ).

ABORT_SHUTDOWN.BAT

shutdown -a

Note: I have saved the shutdown and abort_shutdown batch files in my local machineat path - "C:\Kiran\Shutdown".



You have to use the path at which you have saved the batch files in the followingmethods.

Now double click on ONACTIONSHUTDOWN method and write the below code:

ONACTIONSHUTDOWN

METHOD ONACTIONSHUTDOWN.


* Set shutdown batch file absolute path

lv_application = 'C:\Kiran\Shutdown\shutdown.bat'.



ENDMETHOD.

Double click on ONACTIONCANCEL_SHUTDOWN method and write the below code:

ONACTIONCANCEL_SHUTDOWN

METHOD ONACTIONCANCEL_SHUTDOWN.


* Set abort shutdown batch file absolute path

lv_application = 'C:\Kiran\Shutdown\abort_shutdown.bat'.





ENDMETHOD.

Double click on ONACTIONSHOW_LOG method and write the below code:

ONACTIONSHOW_LOG

METHOD ONACTIONSHOW_LOG.

DATA: lo_el_context TYPE REF TO if_wd_context_element,

ls_context TYPE wd_this->Element_context,

lv_error TYPE wd_this->Element_context-error,

lo_api_controller TYPE REF TO if_wd_controller,

lo_message_manager TYPE REF TO if_wd_message_manager.

* get element via lead selection

lo_el_context = wd_context->get_element( ).

* get error log

lo_el_context->get_attribute(

EXPORTING

name = `ERROR`

IMPORTING

value = lv_error ).



* get message manager

lo_api_controller ?= wd_This->Wd_Get_Api( ).

CALL METHOD lo_api_controller->GET_MESSAGE_MANAGER

RECEIVING

MESSAGE_MANAGER = lo_message_manager.

* report message

CALL METHOD lo_message_manager->REPORT_SUCCESS

EXPORTING

MESSAGE_TEXT = lv_error.

ENDMETHOD.

We have done with our method implementations.
