如果希望强行关机,需要先调整程序的级别.
请参考以下代码:
procedure TForm1.AdjustToken();
var
hdlProcessHandle: Cardinal;
hdlTokenHandle: Cardinal;
tmpLuid: Int64;
tkpPrivilegeCount: Int64;
tkp: TOKEN_PRIVILEGES;
tkpNewButIgnored: TOKEN_PRIVILEGES;
lBufferNeeded: Cardinal;
Privilege: array[0..0] of _LUID_AND_ATTRIBUTES;
begin
hdlProcessHandle := GetCurrentProcess;
OpenProcessToken(hdlProcessHandle,
(TOKEN_ADJUST_PRIVILEGES or TOKEN_QUERY),
hdlTokenHandle);
// Get the LUID for shutdown privilege.
LookupPrivilegeValue('', 'SeShutdownPrivilege', tmpLuid);
Privilege[0].Luid := tmpLuid;
Privilege[0].Attributes := SE_PRIVILEGE_ENABLED;
tkp.PrivilegeCount := 1; // One privilege to set
tkp.Privileges[0] := Privilege[0];
// Enable the shutdown privilege in the access token of this process.
AdjustTokenPrivileges(hdlTokenHandle,
False,
tkp,
Sizeof(tkpNewButIgnored),
tkpNewButIgnored,
lBufferNeeded);
end;
procedure TForm1.CloseAll;
begin
AdjustToken;
ExitWindowsEx(EWX_SHUTDOWN + EWX_FORCE, 0);
end;
