Hi SDN.

I am want to give same functionality i.e. present in CL_GUI_FRONTEND_SERVICES such as create directory, create folder file etc in a web dyn pro.

Is there any class similar to CL_GUI_FRONTEND_SERVICES for WD4A?

To download a file on desktop you can use method of class" cl_wd_runtime_services"

cl_wd_runtime_services=>attach_file_to_response( ). I have provided a code to download a file to desktop.It may help you to gain a good understanding.

  call transformation ('ID') source tab = itab_sflight[] result xml xml_out.


  CALL FUNCTION 'CRM_IC_XML_STRING2XSTRING'
    EXPORTING
      INSTRING         = xml_out
*
  IMPORTING
     OUTXSTRING       = content.

  conv_out = cl_abap_conv_out_ce=>create( encoding = 'UTF-8'  ).


  DATA: lv_filename TYPE string.


* attach the first file
  conv_out->convert( exporting data = xml_out IMPORTING buffer = content  ).
  cl_wd_runtime_services=>attach_file_to_response(
    i_filename  = 'Sales_order_release.xls'
    i_content   = content
    i_mime_type = 'application/msexcel'
    i_in_new_window = i_in_new_window
    i_inplace       = i_inplace ).

Rahul, which is your requirement?

Have you seen something similar to your expectation working in Internet environment?

If I guess well you'll need to ZIP and download it (there is an ABAP class to zip everything you want).

Thanks a lot Sergio for giving me such a great idea........!

But i think SAP will do a great job if they manage to create a class similar to CL_GUI_FRONTEND_SERVICES .....

WD4A application runs in a Browser where security does not allow a lot of things...

So what you can do is upload or download; no way to execute a command or browse the PC filesystem.

You should find what you are looking for in the following pages:
