GUI_GET_REGVALUE
GUI_SET_REGVALUE

 

ROOT：

  O: HKEY_CLASSES_ROOT

  1: HKEY_CURRENT_USER

  2: HKEY_LOCAL_MACHINE

  3: HKEY_USERS

 

注：对REG_DWORD类型的键值操作有问题

 

 

比较好的方法是用CL_GUI_FRONTEND_SERVICES：

 

REPORT  z_barry_test NO STANDARD PAGE HEADING .

 

DATA: value TYPE i.

 

CALL METHOD cl_gui_frontend_services=>registry_get_dword_value
  EXPORTING
    root                 = cl_gui_frontend_services=>hkey_local_machine
    key                  = 'SOFTWARE\IBM\ConfigUtil\InstallInfo'
    value                = 'TPCU'
  IMPORTING
    reg_value            = value
  EXCEPTIONS
    cntl_error           = 1
    error_no_gui         = 2
    not_supported_by_gui = 3
    OTHERS               = 4.

 

CALL METHOD cl_gui_cfw=>flush.

 

WRITE value .
