Problem convert string to table

Former Member — Tue, 31 May 2011 18:54:41 GMT

Hi guys.

I have a long string in BASE64, using the FM SSFC_BASE64_DECODE, I'm able to decode the base64 string to a normal string.

Now, the problem is that i need to convert that long string into a table and then save it as .pdf in the local pc.

I tried using the FM CONVERT_STRING_TO_TABLE but it gives me a dump. This is the code that i have. The w_result is the string in base64 that i get from a webservice.


data: w_result TYPE string, 
        fic_binario TYPE xstring.
DATA: string_binario TYPE string.

  DATA: BEGIN OF lines OCCURS 100,
  tdline(1024) TYPE x.
  DATA: END OF lines.

  CALL FUNCTION 'SSFC_BASE64_DECODE'
    EXPORTING
      b64data = w_result
    IMPORTING
      bindata = fic_binario.

  string_binario = fic_binario.

* Dump
  CALL FUNCTION 'CONVERT_STRING_TO_TABLE'
    EXPORTING
      i_string         = string_binario
      i_tabline_length = 1024
    TABLES
      et_table         = lines.

* Also i tried this: DUMP as well

  DATA: lv_divisor TYPE i,
  lv_resto TYPE i,
  lv_longitud TYPE i,
  lv_indice TYPE i.

  DO.

    lv_longitud = STRLEN( string_binario ).

    lv_divisor = lv_longitud DIV 256.
    lv_resto = lv_longitud DIV 256.

    lv_indice = 256 * sy-index.

    lines-tdline = string_binario+lv_indice(256).

    APPEND lines.
    CLEAR lines.

    IF lv_divisor IS INITIAL.

      EXIT.

    ENDIF.

  ENDDO.

How can i convert that string that I get from the FM SSFC_BASE64_DECODE to a table??? so then i can download it to a local pc????

Regards

What do the dumps say?

Hi Rob the dump says:

The statement

"MOVE src TO dst"

requires that the operands "dst" and "src" are convertible.

Since this statement is in a Unicode program, the special conversion

rules for Unicode programs apply.

In this case, these rules were violated.

How is the variable you are passing to TABLE defined?

Hi,

the variable string_binario contains the value after i decode the string in base64. Until there, it seems to be ok. That variable is a string that containes the info, that must be convert in a table and then download to a local pc in .pdf


  DATA: BEGIN OF lines OCCURS 100,
  tdline(1024) TYPE x.
  DATA: END OF lines.

  DATA: string_binario TYPE string.

  CALL FUNCTION 'CONVERT_STRING_TO_TABLE'
    EXPORTING
      i_string         = string_binario
      i_tabline_length = 1024
    TABLES
      et_table         = lines.

other option is


  DATA: lv_divisor TYPE i,
  lv_resto TYPE i,
  lv_longitud TYPE i,
  lv_indice TYPE i.

  DO.

    lv_longitud = STRLEN( string_binario ).

    lv_divisor = lv_longitud DIV 256.
    lv_resto = lv_longitud DIV 256.

    lv_indice = 256 * sy-index.

    lines-tdline = string_binario+lv_indice(255).

    APPEND lines.
    CLEAR lines.

    IF lv_divisor IS INITIAL.

      EXIT.

    ENDIF.

  ENDDO.

but this option also gives me a dump.

the dumps that gives me the second option is:

Illegal access to a string (offset+length too large)

An exception occurred that is explained in detail below.

The exception, which is assigned to class 'CX_SY_RANGE_OUT_OF_BOUNDS', was not

therefore caused a runtime error.

The reason for the exception is:

In the running program "ZTEST003", part of a string was about to be accessed

via offset and length.

However, the total of offset (157696) and length (255) exceeded the current

length of the string (157874).

This kind of access is illegal.

the dump is getting after the sy-tabix = 615

Hi,

if i change that, and using the FM * CONVERT_STRING_TO_TABLE*

it gives me a dump:

I'm going to check with the another option to see how it works....

I used the second option and it pass without dumps.

but i can't open the file


CALL FUNCTION 'GUI_DOWNLOAD'

the acrobat says that the file is damage...

Thanks

the variable string_binario has sth like this : 255044462D312E330D0A25F6E4FCDF0D0A312030206F626A0D0A3C3C0D0A2F54797065202F436174616C6F670D0A2F50616765732032203020520D0A3E3E0D0A656E646F626A0D0A332030.............

but i can't get it full, even i debbug the program, i can't get the whole value of the variable.

Hi,

Write like the below :

DATA: lv_divisor TYPE i,

lv_resto TYPE i,

lv_longitud TYPE i,

lv_temp_length type i,

lv_remaining type i,

lv_indice TYPE i.

lv_longitud = STRLEN( string_binario ).

DO.

clear : lv_temp_length.

lv_indice = 256 * sy-index.

lv_temp_length = lv_indice + 256.

if lv_temp_length < lv_longitud.

lines-tdline = string_binario+lv_indice(256).

else.

lv_remaining = lv_temp_length - lv_longitud.

lines-tdline = string_binario+lv_indice(lv_remaining).

APPEND lines.

CLEAR lines.

exit.

endif.

APPEND lines.

CLEAR lines.

ENDDO.

Srini.

Hi Miguel,

Once you have the binary in the XSTRING, you could convert that into a table and download using GUI_DOWNLOAD.

Check with the below code, no need to put it in a string just to use the FM "CONVERTSTRINGTOTABLE.


  DATA: li_contents         TYPE TABLE OF sdokcntbin,
        lw_contents         TYPE sdokcntbin,
        l_file_length       TYPE i,
        l_flag              TYPE c,
        l_off               TYPE i,
        l_len               TYPE i.

  TRY.
      l_len = XSTRLEN( fic_binario ).
      l_file_length = l_len.

      WHILE l_flag IS INITIAL.

        IF l_len LE 1022.
          lw_contents-line = fic_binario+l_off(l_len).
          l_flag = 'X'.
        ELSE.
          lw_contents-line = fic_binario+l_off(1022).
          l_off = l_off + 1022.
          l_len = l_len - 1022.
        ENDIF.

        APPEND lw_contents TO li_contents.

      ENDWHILE.

* Download the ITAB li_contents[].
endtry.

Note: When you are downloading with GUI_DOWNLOAD, you might (not that you should) need to use a corresponding codepage.

Reasons for the short dump you are getting,


"MOVE src TO dst"
requires that the operands "dst" and "src" are convertible.

DATA: BEGIN OF lines OCCURS 100,

tdline(1024) TYPE x.

DATA: END OF lines.

You have defined the lines table as that of raw, while internally the convert to string FM expects a string/char type table, change the above data definition to C instead of X and the FM will work fine, but the data will not be valid to be opened as a PDF anymore i guess.


Errores tiempo ejec. STRING_OFFSET_LENGTH_TOO_LARGE
Excepción CX_SY_RANGE_OUT_OF_BOUNDS

I think the above dump is because of the below line, here you have hardcoded the offset value, which will work fine till the last subset of the string is reached, and if the last subset happens to be less than 255 characters, the offset becomes too large.

lines-tdline = string_binario+lv_indice(255).

Hi Chen.

I did what u said and it works, thanks very much.

Also, i use


    CALL FUNCTION 'GUI_DOWNLOAD'
      EXPORTING
        filename = 'C:\Fichero100.pdf'
        filetype = 'BIN'
      TABLES
        data_tab = li_contents.

without filetype = 'BIN' the .PDF file doesnt work.

I dont know why, the website doesnt show me the option to give points....any clue???

I'm going to have it, just the website doesnt show me that...when i figuret out, i will do it.

Thanks to all.

Regards
