method GET_WINDOWS_DIRECTORYofCL_GUI_FRONTEND_SERVICES class givingproblem

[Former Member]

hey guys,

in my program b4 calling gui_download i need to take the path of desktop .

so i am calling the method GET_WINDOWS_DIRECTORYofCL_GUI_FRONTEND_SERVICES

CREATE OBJECT v_guiobj.

CALL METHOD v_guiobj->GET_DESKTOP_DIRECTORY

changing

DESKTOP_DIRECTORY = V_DESKTOP_DIRECTORY.

if sy-subrc = 0.

CONCATENATE V_DESKTOP_DIRECTORY '\smrt' '.pdf' INTO V_DESKTOP_DIRECTORY.

endif.

and then coding for

CALL FUNCTION 'GUI_DOWNLOAD'

follows..

the problem i am facing is..

the variable V_DESKTOP_DIRECTORY is not getting its value after the method is called......

why?

how to correct?

[matt]

Which method are you calling? Your post title says GET_WINDOWS_DIRECTORY and your code says GET_DESKTOP_DIRECTORY.

Whichever, they are static methods. So you don't create an instance of them. You call them

CALL METHOD CL_GUI_FRONTEND_SERVICES=>GET_WINDOWS_DIRECTORY...

CALL METHOD CL_GUI_FRONTEND_SERVICES=>GET_DESKTOP_DIRECTORY...

And why are you then using the obsolete FM GUI_DOWNLOAD?

Instead use CL_GUI_FRONTEND_SERVICES=>GUI_DOWNLOAD...

yea

i am calling GET_DESKTOP_DIRECTORY.

mstake in title..

also i have used

CL_GUI_FRONTEND_SERVICES=>GUI_DOWNLOAD...and seen..

yet no use..

CALL METHOD CL_GUI_FRONTEND_SERVICES=>GET_DESKTOP_DIRECTORY

changing

DESKTOP_DIRECTORY = V_DESKTOP_DIRECTORY.

if sy-subrc = 0.

endif.

doesnot give any value into V_DESKTOP_DIRECTORY..

why?

[Former Member]

intrestingly,

when i use

CALL METHOD CL_GUI_FRONTEND_SERVICES=>GET_DESKTOP_DIRECTORY

changing

DESKTOP_DIRECTORY = V_DESKTOP_DIRECTORY.

if sy-subrc = 0.

endif.

or

CALL METHOD CL_GUI_FRONTEND_SERVICES=>GET_WINDOWS_DIRECTORY

changing

WINDOWS_DIRECTORY = V_DESKTOP_DIRECTORY.

if sy-subrc = 0.

endif.

V_DESKTOP_DIRECTORY gets correct value

at the end of the call

CALL METHOD CL_GUI_FRONTEND_SERVICES=>GUI_DOWNLOAD

• CALL FUNCTION 'GUI_DOWNLOAD'

EXPORTING

bin_filesize = v_bin_filesize

filename = V_DESKTOP_DIRECTORY

filetype = 'BIN'

changing

DATA_TAB = it_lines

EXCEPTIONS

file_write_error = 1

no_batch = 2

gui_refuse_filetransfer = 3

invalid_type = 4

no_authority = 5

unknown_error = 6

header_not_allowed = 7

separator_not_allowed = 8

filesize_not_allowed = 9

header_too_long = 10

dp_error_create = 11

dp_error_send = 12

dp_error_write = 13

unknown_dp_error = 14

dp_timeout = 18

file_not_found = 19

dataprovider_exception = 20

control_flush_error = 21

OTHERS = 22.

IF sy-subrc <> 0.

i found this in debugging..

value of V_DESKTOP_DIRECTORY is ' ' before call of CALL METHOD CL_GUI_FRONTEND_SERVICES=>GUI_DOWNLOAD

but correct value is passed at the end...

but then during call

CALL METHOD CL_GUI_FRONTEND_SERVICES=>GUI_DOWNLOAD

its taking ' ' and not able to download...

pls help

After your call to GET_DESKTOP_DIRECTORY, CALL METHOD cl_gui_cfw=>flush. It worked nicely for me. Obviously the problem described in the OSS note above has been fixed.

DATA: v_desktop_directory TYPE string.

CALL METHOD cl_gui_frontend_services=>get_desktop_directory
  CHANGING
    desktop_directory    = v_desktop_directory.

CALL METHOD cl_gui_cfw=>flush.

WRITE v_desktop_directory.
