Issues in Download File from Server to PC

Question

Hi Experts,
i am havin requirement to download a File and show it to user in open/Sava dialog box.
i have tried both way to achieve this.
1)  cl_wd_runtime_services 2 File Download Elements
here is coding for cl_wd_runtime_services
  CONCATENATE 'C:\temp\'
                     stru_ctx_resume-cv_language
                     stru_ctx_resume-cv_type
                     stru_ctx_resume-oprn_role
                     lv_version
                      '.pdf' INTO lv_filename.
        lv_filetype = 'application/pdf'.
        lr_conv_out = cl_abap_conv_out_ce=>create( encoding = 'UTF-8' ).
Showing Downloaded File to new Window.
        cl_wd_runtime_services=>attach_file_to_response(
          i_filename  = lv_filename
          i_content   = lv_filecontent " Its file Byte Array
          i_mime_type = lv_filetype
          i_in_new_window = abap_false
          i_inplace       = abap_false ).
Problem Statement: Filedownload is working perfect, the only prolem is that IE give warning message before download, i want to get rid of this warning message so i opted for File Download UI Element.
2) File Dowload Element:
i have a file download element in a table collumn, this table is mapped to a node Called CTX_Resume, file download element's data property is mapped to attribute called file_content of type xSTring, this attribute is in node called data which is child node of CTX_Resume.(1:N, Lead Selection True, Singleton True)
so in summary
CTX_Resume(Node): Mapped to table
    File_DATA(Sub Node of CTX_Resume): It has Supply methodName: Sup_File_Data
          File_Content(Type Xstring) Mapped to Data property of Filedownload
Codding at Supply Method is
METHOD sup_file_data .
data declaration
  DATA:
    stru_file_data            TYPE wd_this->element_file_data,
    stru_resume           TYPE wd_this->element_ctx_resume,
        lv_filecontent TYPE zall_empprof_file_content,      "#EC NEEDED
        lv_error_text TYPE zall_empprof_error_text,         "#EC NEEDED
if wd_this->mv_first_time = abap_false.
  CALL METHOD parent_element->get_static_attributes
    IMPORTING
      static_attributes = stru_resume.
  if not stru_resume is INITIAL.
    MOVE stru_resume-cv_version TO lv_version.
  CALL METHOD wd_assist->download_cv
    EXPORTING
      im_doc_id       = stru_resume-doc_id
      im_doc_type     = 'pdf'
      im_doc_version  = stru_resume-cv_version
    IMPORTING
      ex_file_content = lv_filecontent " File Byte Array
      ex_error_text   = lv_error_text.
  IF lv_error_text IS INITIAL.
    move lv_filecontent to stru_file_data-file_content.
  ENDIF.
else.
  wd_this->mv_first_time = abap_false.
endif.
  node->bind_structure(
    new_item =  stru_file_data
    set_initial_elements = abap_true ).
ENDMETHOD.
Problem Statement: this works perfect only at first time as i cant controll the triggering of Supply method, to get rid of this i want whenever user clicks on File Download Link, it must trigger supply method.
My table doesnt have selections properites = none.
hope i have given sufficiant information about the problem,
please help me....
Regards
Manish.

Answer 1

It depends on your browser mime type setting.
If you donload a doc file for example and the client's browser is set as to open doc files automatically with word application you will not get the save file dialog box.
Its all dependent on the client machine setting and not on forms.
