any alternative for this codding.

hello Tech Experts,

I'm developing a simple application in wd for uploading text file into ztable. I've found some sources to implement, I had a doubt in the following code

CALL FUNCTION 'HR_KR_XSTRING_TO_STRING'
  EXPORTING
  in_xstring = l_xstring
  IMPORTING
  out_string = l_string.

  SPLIT l_string AT cl_abap_char_utilities=>newline INTO TABLE i_data.
* Bind With table Element.
  LOOP AT i_data INTO l_string.



  SPLIT l_string AT cl_abap_char_utilities=>horizontal_tab INTO TABLE fields.

READ TABLE fields INTO lv_field INDEX 1.
  fs_table-name = lv_field.
  READ TABLE fields INTO lv_field INDEX 2.
  fs_table-age = lv_field.

  APPEND fs_table TO t_table1.



  ENDLOOP.

  lo_nd_sflight = wd_context->get_child_node( 'DATA_TAB' ).
  lo_nd_sflight->bind_table( t_table1 ).

this code works fine, But inside the loop we are reading the value field by field using index in this case it has just 2 records, what if they are n number of records. Do I have to use those read statements for 'n' times.

please help me if there is any alternative solution for this.

thank you,

Regards,

Hi,

Alternative can be this for N-Fields.

SPLIT l_string AT cl_abap_char_utilities=>newline INTO TABLE i_data.

LOOP AT i_data INTO l_string.

SPLIT l_string AT cl_abap_char_utilities=>horizontal_tab INTO

                                   <workarea>-field1

                                   <workarea>-field2

                                   <workarea>-field3

                                   <workarea>-field4

                                   <workarea>-field5

                                   <workarea>-field6

                                             :

                                             :

append <workarea> to <itab>.

clear <workarea>.                        

ENDLOOP.

Note : <itab> is an internal table where your required fields are declared.

Hope this helps you.

Thanks

Hi,

You can download the contents using cl_wd_runtime_services=>attach_file_to_response( ) method by passing respective MIME types.

For reference you can check 'DEMO_ADOBE_OFFLINE' wdp component.

hello KH,

I copied this code from standard one

data:

     lr_pdf_node type ref to if_wd_context_node,

     pdf         type xstring.

   lr_pdf_node = wd_context->get_child_node( wd_this->wdctx_UPLOAD_EXCEL ).

   lr_pdf_node->get_attribute( exporting name = 'FILE_DATA' importing value = pdf ).

cl_wd_runtime_services=>attach_file_to_response(

     i_filename      = 'DemoAdobeOffline.pdf'

     i_content       = pdf

     i_mime_type     = 'application/pdf'

     i_in_new_window = ABAP_FALSE

     i_inplace       = ABAP_false ).

I would like to download the pdf in local system. but they didn't specify any location to download in that method. can you please help me.

Thank you,

Hi KH,

I did that too.

cl_wd_runtime_services=>attach_file_to_response(

     i_filename      = 'C:\DemoAdobeOffline.pdf'

     i_content       = pdf

     i_mime_type     = 'application/pdf'

     i_in_new_window = ABAP_FALSE

     i_inplace       = ABAP_false ).

It didn't work. Actually my requirement is to download an internal table to pdf format.

please help.
