How to store Rawstring to itab & 'strlen' not working for Rawstring ?

former_member54229 — Fri, 27 May 2005 02:48:10 GMT

Many thanks for your help.

Could you clarify Step3 & 4 (refer as below Raja's post) since 'strlen' is not working for xstring (rawstring)?

And how to reverse the 'CONCATENATE' process to store xstring to itab ? Rawstring seems take maximum length of 10,880 char and we have to compress our big file at first.

Have a nice weekend!

Waylan

Here is the step by step approach.

1. read the raw string from the table.

2. unzip using

CALL METHOD cl_abap_gzip=>decompress_binary EXPORTING gzip_in = <compressed binary string > IMPORTING raw_out = <decompressed binary string>.

3. find the length of the xstring - strlen( <variable> )

4. move the decomressed xstring to a itab

5. use GUI_download , passing file size and setting the file type to BIN

Hope this helps.

Regards

Raja

Any clue to store rawstring to internal table ?

strlen is not available for rawstring as well.

Thanks,

Hi Waylan,

you should use xstrlen in place of strlen to get the length of xstring.

By the way , you can check the program below that converts a text file --> xtring -->binary --->text file again and then downloads on your PC as 'C:\stringtest.txt'.


REPORT  ZTEST_XSTRING                           .

TYPES : BEGIN OF ty_text,
          text_field(1000) TYPE C,
        END OF ty_text.

TYPES : BEGIN OF ty_binary,
          BINARY_field(1000) TYPE C,
        END OF ty_binary.

DATA : lv_xstring type XSTRING.
DATA : lt_binary type table of ty_binary with header line.
DATA : lt_text type table of ty_text with header line.
DATA : lt_text_out type table of ty_text with header line.

DATA : X_OUTFILE type string.

lt_text-text_field = 'Hello'.
append lt_text.

lt_text-text_field = 'Hi'.
append lt_text.

lt_text-text_field = 'How r u?'.
append lt_text.

Hi,

Sorry, it was weekend (thursdaty and friday), thus couldnt reply on time.

to compute the xstring length.

use xstrlen ( xstring ).

itab for storing the xstring.

data: begin of bin_tab ,

val type xstring ,

end of bin_tab .

now move the raw value which you read from the DB table into this table and use gui_download with file type 'BIN'.

Hope this is clear.

Regards

Raja

I don't think it will work that way.

You can't download Hexa value as a Binary. You need to first convert it to Binary.

Check my previous posting.

Thanks,

Ram

this is a follow up of a earlier thread, where the upload of binary string was discussed.

Oops...

So you guys are discussing this for quite some time and I just jumped into it...

Ok..in that case it might work

Sorry, but not sure. I mean, the itab that you declared has a xstring ( Hexa String ) as the component. And then it is being downloaded as Binary.

Does that work?

Cheers,

Ram

Thanks for your timely response.

We already solved it ourselves. Xstring works perfectly.

Best regards,
