class method for generating URL for Web Repository

[Former Member]

Hi,

I want to know METHOD not FUNCTION MODULES for generating URL for Web Repository. A picture is stored in Web Repository (SMW0). The URL is used in CL_GUI_PICTURE=>LOAD_PICTURE_FROM_URL. I've tried LOAD_PICTURE_FROM_URL, but no valid URL generated.

Hi,

The Function Module WWW_GET_MIME_OBJECT is used to get the MIME object for the Picture

and DP_CREATE_URL is used to create an URL.

Check the below code...it may helps you....

Data: g_picture           type ref to cl_gui_picture,

      g_custom_container2 type ref to cl_gui_custom_container,

*-- URL

data: v_url(255)          type c.                " URL-field

data: pic_data            like w3mime occurs 0.

data: pic_size            type i.

  call method cl_gui_datamanager=>on_input.

• display LOGO

  create object g_custom_container2         exporting container_name = 'LOGO'.   create object g_picture         exporting parent = g_custom_container2.

• Load the picture data from the WebRFC database into the internal
• table pic_data.

  perform load_pic_from_db

          tables pic_data

          using 'Z_LOGO'

          changing pic_size.

  call function 'DP_CREATE_URL'

       exporting

            type    = 'image'

            subtype = 'X-UNKNOWN'

       tables

            data    = pic_data

       changing

            url     = v_url.

  call method g_picture->load_picture_from_url

       exporting url = v_url.

form load_pic_from_db

     tables pic_data

     using pic_name

     changing pic_size.

  data query_table like w3query occurs 1 with header line.

  data html_table like w3html occurs 1.

  data return_code like  w3param-ret_code.

  data content_type like  w3param-cont_type.

  data content_length like  w3param-cont_len.

  clear query_table.

  query_table-name = '_OBJECT_ID'.

  query_table-value = pic_name.

  append query_table.

  call function 'WWW_GET_MIME_OBJECT'

       tables

            query_string        = query_table

            html                = html_table

            mime                = pic_data

       changing

            return_code         = return_code

            content_type        = content_type

            content_length      = content_length

       exceptions

            parameter_not_found = 2

            others              = 3.

  if sy-subrc = 0.

    pic_size = content_length.

  endif.

endform.                               " LOAD_PIC_FROM_DB

Thank you for your reply. As I mentioned, I am looking for Class Method replacing those function modules; but thank you all the same.

Hi,

Why do you need methods? Instead you can use FM's itself.

Just to explore classes.
