ABAP文件选择框函数
因为WS_FILENAME_GET已经被废弃所以使用接口CL_GUI_FRONTEND_SERVICES来实现本地文件的选择.
用接口类CL_GUI_FRONTEND_SERVICES实现的方法
CALL METHOD CL_GUI_FRONTEND_SERVICES=>FILE_OPEN_DIALOG
EXPORTING
WINDOW_TITLE = ‘选择‘
DEFAULT_EXTENSION = ‘XLS‘
DEFAULT_FILENAME = ‘defaultfilename‘
FILE_FILTER = ‘Excel文件(*.XLS)|*.XLS|全部文件 (*.*)|*.*|‘
* INITIAL_DIRECTORY =
* MULTISELECTION =
* WITH_ENCODING =
CHANGING
FILE_TABLE = g_text
RC = rc
* USER_ACTION =
* FILE_ENCODING =
* EXCEPTIONS
* FILE_OPEN_DIALOG_FAILED = 1
* CNTL_ERROR = 2
* ERROR_NO_GUI = 3
* NOT_SUPPORTED_BY_GUI = 4
* others = 5
.
如图
接口CL_GUI_FRONTEND_SERVICES 的其他几个常用方法:
CALL METHOD CL_GUI_FRONTEND_SERVICES=>FILE_EXIST
EXPORTING
FILE = LW_FILE
RECEIVING
RESULT = LW_RESULT
EXCEPTIONS
CNTL_ERROR = 1
ERROR_NO_GUI = 2
WRONG_PARAMETER = 3
NOT_SUPPORTED_BY_GUI = 4
OTHERS = 5.
CALL METHOD CL_GUI_FRONTEND_SERVICES=>DIRECTORY_EXIST
EXPORTING
DIRECTORY = LW_PATH
RECEIVING
RESULT = LW_RESULT
EXCEPTIONS
CNTL_ERROR = 1
ERROR_NO_GUI = 2
WRONG_PARAMETER = 3
NOT_SUPPORTED_BY_GUI = 4
OTHERS = 5.
CALL METHOD CL_GUI_FRONTEND_SERVICES=>FILE_SAVE_DIALOG
EXPORTING
WINDOW_TITLE = LW_TITLE
CHANGING
FILENAME = LW_FILENAME
PATH = LW_PATH
FULLPATH = LW_FULLPATH
USER_ACTION = LW_ACTION
EXCEPTIONS
CNTL_ERROR = 1
ERROR_NO_GUI = 2
NOT_SUPPORTED_BY_GUI = 3
OTHERS = 4.
CALL METHOD CL_GUI_FRONTEND_SERVICES=>DIRECTORY_BROWSE
EXPORTING
WINDOW_TITLE = ‘选择一个路径‘
INITIAL_FOLDER = ‘Z:\‘
CHANGING
SELECTED_FOLDER = lw_folder
EXCEPTIONS
CNTL_ERROR = 1
ERROR_NO_GUI = 2
NOT_SUPPORTED_BY_GUI = 3
others = 4
.
方法描述:弹出选择目录对话框
SELECTED_FOLDER返回选择目录
