cl_abap_gzip

Hi,

I have used CL_ABAP_GZIP to compress a file and I get the xstring as output and its length.

  TRY.
      CALL METHOD cl_abap_gzip=>compress_binary
        EXPORTING
          raw_in         = raw_in
          raw_in_len     = raw_in_len
          compress_level = 6
        IMPORTING
          gzip_out       = gzip_out
          gzip_out_len   = gzip_out_len.
    CATCH cx_parameter_invalid_range .
    CATCH cx_sy_buffer_overflow .
  ENDTRY.

Now, I would like to download it, and I use gui_download. But gui_download accepts parameters in table:

    CALL METHOD cl_gui_frontend_services=>gui_download
      EXPORTING
        bin_filesize            = gzip_out_len
        filename                = lv_filename
        filetype                = 'BIN'
      CHANGING
        data_tab                = data_tab.

Do you know how can I get my compressed xstring data (gzip_out) and load into table form (data_tab)? And which file extension should my lv_filename be? (ex: compressed.gzip)??

kindly advise.

thanks & regards,

ginnie

Have to tried to use the gzip_out table in GUI_DOWNLOAD?

Please try like this:

   CALL METHOD cl_gui_frontend_services=>gui_download
      EXPORTING
        bin_filesize            = gzip_out_len
        filename                = lv_filename   " << "C:tempcomp.zip"
        filetype                = 'BIN'
      CHANGING
        data_tab                = gzip_out.

Hi Naimesh,

gzip_out from cl_abap_gzip is type xstring. It is not compatible with the type of data_tab. How can i convert this xstring to the data_tab? Is there any FM to convert it?

Kindly advice.

Try with this FM : SCP_TRANSLATE_CHARS.

Pass INBUFF as your xstring data, recieve in OUTBUFF data.

Hi,

Better to use that SXPG...etc commands to compress the files rather then using CL_ABAP_GZIP. This class does nto wirk properly.

Please have a look at function module SCMS_XSTRING_TO_BINARY
