FM for checking valid drive on PC

Former Member — Wed, 15 Feb 2006 10:16:29 GMT

Hi all,

I am developing an interface.

There is one file which is to be uplaoded in my code. I am doing some processing on that code and downloading that file on PC.

User will enter the input & output file name. When user will enter the path I want o check for the drive. Means if user has only C & D drive on my PC & user has given F drive while giving the output file name then it should give error.

Is there any FM or method available for this? I have tried with FM "PC_CHECK_PATH_WITH_DRIVE" but it is not giving me desired result.

Please help.... Its urgent....

Thanks in advance.

Deepti

Hi Deepthi,

Try this:

A sample code:

  DATA: li_filetable TYPE STANDARD TABLE OF file_table,
        lv_return TYPE i,
        lw_filetable TYPE file_table.

  CALL METHOD cl_gui_frontend_services=>file_open_dialog
     EXPORTING
       window_title            = 'Select file for download'
       default_extension       = '.txt'

       initial_directory       =  'C:'
     CHANGING
       file_table              = li_filetable
       rc                      = lv_return
     EXCEPTIONS
       file_open_dialog_failed = 1

       OTHERS                  = 4
           .
  IF sy-subrc <> 0.
    MESSAGE e003 WITH text-015.
  ELSE.
    READ TABLE li_filetable INTO lw_filetable INDEX 1.
    p_fnam2 = lw_filetable-filename.
  ENDIF.


ENDFORM.                    " f1003_f4_hlp_for_pc_file

Hi deepti,

1. Why do u want to check the DRIVER?

2 in FM GUI_UPLOAD,

the file name is specified FULL,

along with the drive and path name.

eg. d:\myfolder\myfile.txt

3. If the file (along with the path and drive)

does not exist,

the the FM will give EXCEPTION

saying that -- file not found.

4. So, it checks for the DRIVE as well as FULL PATH Name.

regards,

amit m.

Hi Amit

I don't have problem while uploading the file. I have problem in GUI_DOWNLOAD.

As I said if my PC has C & D drive only and I am giving F drive in the path name it is not giving any error.

Thanks & Regards

Hi Deepti,

check this code..

i checked it using e drive , pass the driver dynamically and get the result.

Report ZTEST_DRIVECHECK.
data: rc type c.

CALL METHOD CL_GUI_FRONTEND_SERVICES=>DIRECTORY_EXIST
  EXPORTING
    DIRECTORY            = 'F'
  RECEIVING
    RESULT               = rc
  EXCEPTIONS
    CNTL_ERROR           = 1
    ERROR_NO_GUI         = 2
    WRONG_PARAMETER      = 3
    NOT_SUPPORTED_BY_GUI = 4
    others               = 5
        .
IF SY-SUBRC <> 0.
 MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
            WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.


if rc = space.
Write: 'F drive exists'.
else.
Write: 'F drive is not there'.
endif.

Hi,

Pls note Ws_DOWNLOAD is preferred to gui_download.


*p_fnam2 LIKE rlgrap-filename.

  CALL FUNCTION 'WS_DOWNLOAD'

       TABLES
            data_tab                = i_download
       EXCEPTIONS
            file_open_error         = 1
            file_write_error        = 2
            invalid_filesize        = 3
            invalid_type            = 4
            no_batch                = 5
            unknown_error           = 6

            customer_error          = 9
            OTHERS                  = 10.

  IF sy-subrc = 0.
    MESSAGE i352.                          "File downloded successfully

Hi Deepti,

1. file_not_found = 19

2. sy-subrc = 19 if drive is wrong.

3. It surely gives error (by value of sy-subrc <> 0)

after the FM is called.

4. try this code (just copy paste in new program)

5. It WILL GIVE ERROR

REPORT abc.

Hello Deepti,

Try this...

data: FILE_TABLE type table of SDOKPATH,

wa_file type sdokpath,

line type i,

DIR_TABLE type table of SDOKPATH.

parameter path(30) type c default 'C:\KARTHIKEYAN\'.

CALL FUNCTION 'TMP_GUI_DIRECTORY_LIST_FILES'

EXPORTING

directory = path

tables

file_table = file_table[]

dir_table = dir_table[].

describe table file_table lines line.

if line = 0.

write : 'invalid path'.

else.

write : 'valid path'.

endif.
