Using xString to display as PDF in a custom container

[former_member184386]

Hello gurus,

I have a SmartForm that was converted to xstring using CONVERT_OTF, I want to use the xstring now to display it as PDF inside a custom container.

I tried using class cl_gui_html_viewer together with cl_gui_custom_container but the form always turns up blank.

Convert xstring to binary table to pass to the LOAD_DATA method
  call function 'SCMS_XSTRING_TO_BINARY'
    exporting
      buffer     = lv_content
    tables
      binary_tab = lt_data.

  call method pdf_html_control->load_data
    exporting
      url          = l_myurl
      size         = l_pdf_size
      type         = 'application'                          "#EC NOTEXT
      subtype      = 'pdf'                                  "#EC NOTEXT
    importing
      assigned_url = l_url
    changing
      data_table   = l_pdf_data
    exceptions
      others       = 1.

  call method g_html_control->show_url( url = lv_url
    in_place = 'X' ).

Need advice on how to accomplish this, or is there another way to do this?

Thanks in advance.

I've done this using FM CONVERT_OTF_2_PDF not CONVERT_OTF.

Thanks for the quick reply Rob, but what I actually wanted to figure out is how to display the PDF inside a custom container. Regards.

Here is some code I have that is used in an ESS application. But I think it wall also work in R3:

DATA: html_container TYPE REF TO cl_gui_custom_container,
      html_viewer TYPE REF TO cl_gui_html_viewer,
      url(80) TYPE c,

module display_pdf output.

CREATE OBJECT html_container
  EXPORTING
    container_name = 'PDF_VIEWER'.
CREATE OBJECT html_viewer
  EXPORTING
    parent = html_container.

url = 'PDF.pdf'.
CALL METHOD html_viewer->load_data
  EXPORTING
    url          = url
    size         = size
    type         = 'text'
    subtype      = 'pdf'
  IMPORTING
    assigned_url = url
  CHANGING
    data_table   = lines_pdf[].

CALL METHOD html_viewer->show_data
  EXPORTING
    url      = url
    in_place = 'X'.

ENDMODULE.                 " DISPLAY_PDF  OUTPUT

Did you have to convert the internal table lines_pdf[] from xstring to text or binary?

[Former Member]

No conversion from the FM output (like TDLINE).

Hi Rob,

What's the table parameter DOCTAB_ARCHIVE in FM CONVERT_OTF_2_PDF do?

[Former Member]

It's a table that's (I think) returned by the FM. I pass it empty and never look at it.

Hi Rob,

I think I'm almost there, just maybe a small problem - I see a pop-up window that says "File does not begin with '%PDF-'.

Did I miss something here?

Thanks again.

I think it's telling you that the PDF file is corrupt. In fact, it may be empty. Have you looked at the internal table to ensure it is populated?

Is this because we converted our system to Unicode? If yes, is there another step to take perhaps converting the text to xtring or binary?

The OTF table is populated, but after running the FM CONVERT_OTF_2_PDF, the output table (PDF) contains a bunch of ascii characters.
