reading PDF from application server and convert it to Binary

Former Member — Tue, 18 Nov 2014 13:05:43 GMT

Hello Guys,

my goal is to read an PDF from the appication server and store it as an binary.

But i think i handle according a wrong procedure. Maybe some one can help me finding out.

first i read the PDF

using

OPEN DATASET gv_inp_file FOR INPUT IN BINARY MODE.

IF sy-subrc EQ 0.

DO.

READ DATASET gv_inp_file INTO gs_solix-line.

IF sy-subrc EQ 0.

APPEND gs_solix TO gt_solix.

CLEAR gs_solix.

ELSE.

APPEND gs_solix TO gt_solix.

EXIT.

ENDIF.

ENDDO.

CLOSE DATASET gv_inp_file.

the data is now in gt_solix

i concatenate tis into 1 xstring using a perform

PERFORM convert_tab_to_x USING gt_solix

CHANGING gv_len

gx_content.

this makes an long gx_content xstring

and seems to be ok

the FORM is

FORM convert_tab_to_x USING p_rawtab TYPE tabtype_solix

CHANGING p_len TYPE i

p_xstr TYPE xstring.

DATA: l_line TYPE solix,

l_count TYPE i,

l_len TYPE i,

l_rest TYPE i,

l_strlen TYPE i.

DESCRIBE TABLE p_rawtab LINES l_count.

LOOP AT p_rawtab INTO l_line.

IF sy-tabix = l_count.

l_rest = xstrlen( l_line-line ).

CONCATENATE p_xstr l_line-line(l_rest) INTO p_xstr IN BYTE MODE.

ELSE.

CONCATENATE p_xstr l_line-line INTO p_xstr IN BYTE MODE.

ADD 255 TO l_len.

ENDIF.

ENDLOOP.

* total length

ADD l_rest TO l_len.

MOVE l_len TO p_len.

as last part i convert this xstring to binary using

CALL FUNCTION 'SCMS_XSTRING_TO_BINARY'

EXPORTING

buffer = gx_content

IMPORTING

output_length = gv_len

TABLES

binary_tab = gt_bin_data.

and the following standard coding handles this with at the end a wrong result.

is this the method i use ok

or is it better to declare an (big) xstring to read the dataset into and use this straight away

to convert to binary instrad of this method (parts of 255 long)

any suggestions are welcome.

hope you can tell me the how to do this right.

Regards, Frank

Hi Frank

i prefer

READ DATASET into WF_XSTRING (Straight away)

where do you want to store your binary data now? (table with RAWSTRING, SAP DMS, BDS, Contentserver, Archive...)

to convert it into an internal table i also use CALL FUNCTION 'SCMS_XSTRING_TO_BINARY' (good choice!)

i see a lot of developers dealing with binary data using concatenate or split functions, but

in my opinion this is always a unnecessary source of erros, so i am always using the SCMS*STRING* functions

Hello Jörg,

thanks for your answer.

you mean with READ DATASET into WF_XSTRING (Straight away)
that i do not have to use that form convert_tab_to_x anymore.

The binary data has to be stored into archive.

and cause of your preferring SCMS functions i will see for moe of tjhem

Regards, Frank

yes, conversion form not required

use this:

data: gx_content xstring.

OPEN DATASET gv_inp_file FOR INPUT IN BINARY MODE.

if sy-subrc = '0'.

READ DATASET gv_inp_file INTO gx_content. "all in one go

CLOSE DATASET gv_inp_file.

endif.

CALL FUNCTION 'SCMS_XSTRING_TO_BINARY'

EXPORTING

buffer = gx_content

IMPORTING

output_length = gv_len

TABLES

binary_tab = gt_bin_data.

Hi,

Try:

FORM upload_file_2

USING

p_path TYPE pathextern

CHANGING

it_solix TYPE solix_tab .

DATA: big_string TYPE xstring .

DATA: mess TYPE string .

OPEN DATASET p_path FOR INPUT IN BINARY MODE MESSAGE mess .

READ DATASET p_path INTO big_string .

CLOSE DATASET p_path .

CALL METHOD cl_bcs_convert=>xstring_to_solix

EXPORTING

iv_xstring = big_string

RECEIVING

et_solix = it_solix.

ENDFORM . "upload_file_2

Regards.
