Zip files

Former Member — Wed, 03 Nov 2010 14:28:09 GMT

Hello Experts,

I need to zip some unicode txt files that exist in the presentation server...

I did the following steps.. but the final result was not good. Utf8 characters were not displaying well..

1) I load the file from server int an HEX internal table

call function 'GUI_UPLOAD'

exporting

FILENAME = gfile2

IMPORTING

FILELENGTH = bytecount

TABLES

DATA_TAB = hex_tab.

2) then i convert the hex_tab to XSTRING

call function 'SCMS_BINARY_TO_XSTRING'

exporting

input_length = bytecount

importing

buffer = content_x

tables

binary_tab = hex_tab.

3)i do the zipping

call method g_zipper->add

exporting

name = file_name

content = content_x.

call method g_zipper->save

receiving

zip = zip.

4)i convert it again to binary and download it...

"convert to table

call function 'SCMS_XSTRING_TO_BINARY'

exporting

buffer = zip

importing

output_length = bytecount

tables

binary_tab = hex_tab."file_tab.

"Save the file

call function 'GUI_DOWNLOAD'

exporting

" bin_filesize = ''

filename = gfile2

filetype = 'BIN'

" CODEPAGE = '4310'

tables

data_tab = hex_tab."

*******************************

but as i told you the greek language does not shown ok... any ideas why ?

 CALL METHOD CL_GUI_FRONTEND_SERVICES=>GUI_UPLOAD
     EXPORTING
       FILENAME                = FULL_PATH

hello Dear,

I have the same problem.

function -->

SCMS_BINARY_TO_XSTRING

maybe doesnt take care of the greek characters.

Do you have any solution? - (or any work around?)

I apppreciate your help,

Thanks in advance,

Roxani

Hi,

I have specified a link below. Even though the question is unanswered, it has details about a class that reads Unicode data. Please try that and post furher for clarifications.
