Regarding CL_GUI_FRONTEND_SERVICES

Dear forumers,
Is there a method available from the class CL_GUI_FRONTEND_SERVICES that can be used to select and browse for a file in the presentation server?
In other words, is there a method from this class that is similar to the function F4_FILENAME too? Also, is the function F4_FILENAME considered as an obsolete ABAP construct?
I have checked the methods in the class CL_GUI_FRONTEND_SERVICES, and I'm wondering if methods GET_DESKTOP_DIRECTORY or FILE_OPEN_DIALOG can be used for this purpose?
Please help. Thanks.

Hi Deborah,
Try method FILE_OPEN_DIALOG in class CL_GUI_FRONTEND_SERVICES.
For its use, refer the following thread:
Re: class and method can be used instead of F4_FILENAME

Nitin.

Regarding CL_GUI_FRONTEND_SERVICES= FILE_OPEN_DIALOG

I'm using CL_GUI_FRONTEND_SERVICES=>FILE_OPEN_DIALOG to replace WS_FILENAME_GET which is an obsolete function module in ECC6.
WS_FILENAME_GET was making use of the file mask -
',.csv ,.csv ,.txt ,.txt.'
When I use the same string in the file_filter parameter of FILE_OPEN_DIALOG, it doesn't work.
Can somebody tell me the correct string format? I would like *.csv & *.txt as the file mask in the open dialog.
Thanks!

Hi
U can give like this |.csv| ,|.csv |,|.txt |,|.txt.|'
i think it will work.
Thanks

Query regarding cl_gui_frontend_services= get_ip_address

Hi,
I am using the method get_ip_address on class cl_gui_frontend_services to get the IP address of a machine.
However, the wrong IP address appears to be being picked up.
If I do an ip_config, I can see a list of 3 IP addresses, one for each of the following adapters:-
Ethernet Adapter local area connection
Ethernet Adapter Wireless Network Connection
Ethernet Adapter DrayTek Virtual Interface
I want the IP address of the local area connection but this method seems to be picking up one of the other ones.
Does anyone have any ideas on how I get round this?
Thanks,
Ruby

Hi friend,
Also try FM 'THUSRINFO'.
It will return table containing IP address.
Ex:
DATA: BEGIN OF user_tab OCCURS 0.
INCLUDE STRUCTURE uinfo.
DATA: END OF user_tab.
CALL FUNCTION 'THUSRINFO'
TABLES
usr_tabl = user_tab.
LOOP AT user_tab.
WRITE:/ user_tab-hostadr. <--- 'user_tab-hostadr' contains IP address
ENDLOOP.
Thanks..

Hi,
In sap gui was trigered action whih is using smartform and then output was being downloaded and saved as using:

CALL METHOD CL_GUI_FRONTEND_SERVICES=>FILE_SAVE_DIALOG
After the ubgrade this action is not working in web ui.
Anyone knows how to change this to work in web ui?
Thank you in advance

Hi Tanja Lukovic
Pls check the settings defined in the SPRO path CRM->Basic settings->actions under this select your relevant application area and check whether any start/schedule conditions are not met (check in conditions) , apart from this reason there could be other reasons also pls check the trigger processing type (it should be smart form print).
if the actions are already created , you can change actions and conditions.

Cl_gui_frontend_services: possible to change the user for writing files?

Hi,
I'm using the class cl_gui_frontend_services to allow the user to copy a file to a specified network drive (using the method file_copy). The user can open the file again, if he double clicks on a row in a ALV table. So far so good, this works already.
But one requirement for this solution is, that the user can not access the directory where the copied files are stored directly.
Now I'm wondering if it is possible to use a specified system user for copying the files? My idea is to switch to the system user just for the method file_copy. I didn't find a method for doing this yet but maybe somebody knows if this is possible.
Thanks and regards,
Martin

Cl_gui_frontend_services= allow browsing to directory path

Hi guys,
i have created a program to automate the download of joblogs and spools using CALL TRANSACTION SM37 .
currently i am taking the location where files need to be stored from selection screen.
now i want to use cl_gui_frontend_services=>?
to allow browse function to directory path where i need to save the files(i.e spool and joblog).
it will be of great help if you could send me a piece of code using cl_gui_frontend_services=>? which can allow browsing to directory path where i can save the files.
Thanks
Ankit
LnT Infotech,Mumbai

I had the same problem like Adel when calling the browser via cl_gui_frontend_services=>execute().
On my old school XP machine the synchronous start is doing well, but not on my colleagues W7 64 machines.
I used a registrey key to get - in my case - the path to the Internet Explorer.
(htmlfile\shell\open\command)
On W7/64Bit this key contains the path to the 32 bit Binary:
C:\Program Files (x86)\Internet Explorer\IEXPLORE.EXE
If I start this application it's not synchronous, if i hard-code the path 64 bit binary
(C:\Program File\Internet Explorer\IEXPLORE.EXE) the application runs synchronous.
A pragmatic programmer could replace the ' (x86)' in the path, which should work on most Windows platforms

we are using cl_gui_frontend_services=>gui_download to create from an itab an excel file.

Cl_gui_frontend_services= gui_download - wrong behaviour with Windows UAC

Hello,
we are using the method cl_gui_frontend_services=>gui_download to store files on the presentation front end (Windows Vista with UAC).
When the user has no windows rights to the target directory and UAC is active, then the method gui_download stores the file in other directory (C:\Users\<USER_NAME>\AppData\Local\VirtualStore\Windows) and returns with sy-subrc = 0.
In our opinion this is a critical problem but SAP doesn't want to correct it.
What do you think about it?
regards,
Kris

Hello kpsgoutam ,
thank you for your post but it's not an answer for my question. I know how to use 'gui_dowload'. The problem is, it works wrong with UAC and target directory, where you have no rights to write the file.
Consider following code:
REPORT ztest.
DATA:
" to reproduce the problem the UAC must be active
" and you can't have write rights to the target directory
lv_filename TYPE string VALUE 'c:\windows\test.txt',
lt_data TYPE TABLE of string,
lv_data TYPE string,
lv_outlen TYPE i.
lv_data = 'Some test content'.
APPEND lv_data TO lt_data.
CALL METHOD cl_gui_frontend_services=>gui_download
EXPORTING
 filename = lv_filename
IMPORTING
 filelength = lv_outlen

How can i get a file header using this method cl_gui_frontend_services= gui

Hi,
You can use the FM - GUI_DOWNLOAD to specify the headers. It can be done in the following manner -
TYPES: BEGIN OF ty_head, "Structure for header
 h(10) TYPE c,
 END OF ty_head.
DATA: it_head TYPE TABLE OF ty_head WITH HEADER LINE.
"Adding header details
it_head-h = 'Field1'.
APPEND it_head.
it_head-h = 'Field2'.
APPEND it_head.
it_head-h = 'Field3'.
APPEND it_head.
it_head-h = 'Field4'.
APPEND it_head.
CALL FUNCTION 'GUI_DOWNLOAD'
EXPORTING
 filename = p_file
 filetype = 'ASC'
 write_field_separator = 'X'
 header = '00' "<= note this
TABLES
 data_tab = it_tab
 fieldnames = it_head[] "<= Pass your header table here
EXCEPTIONS
 OTHERS = 1.
Hope this helps.

Himanshu
