Shutdown
<![CDATA[

Hi Robert,
Here is the sample app again. The Key points are:
const
SE_SHUTDOWN_NAME = 'SeShutdownPrivilege';
if SetPrivilege(SE_SHUTDOWN_NAME, True) then
ExitWindowsEx(EWX_SHUTDOWN,0)

*************** Start of ShutDown.DPR ***************
program ShutDown;

Windows,

ExitWindowsEx(EWX_SHUTDOWN,0)

MessageDlg('Failed to set privilege', mtError, [mbOK],0);
end.

Re ShutDown: I once got this some time ago.
Maybe it helps
function GetShutDownPriv : boolean;
var
htoken : THandle;
tkp, p : TTokenPrivileges;
retlen : dword;
reply : dword;
begin
Result := False;
if OpenProcessToken(GetCurrentProcess, TOKEN_ADJUST_PRIVILEGES OR
TOKEN_QUERY, htoken) then
begin
if LookupPrivilegeValue(nil, 'SeShutdownPrivilege',
tkp.Privileges[0].luid) then
begin
tkp.PrivilegeCount := 1;
tkp.Privileges[0].Attributes := Se_Privilege_Enabled;
AdjustTokenPrivileges(htoken, False, tkp, SizeOf(tkp), p, retlen);
reply := GetLastError;
if reply = Error_Success then
Result := True;
end;
end;
end;
begin
Randomize;
if GetShutDownPriv then
InitiateSystemShutdown(nil, pchar('This is it - the very end!'), 10,
True, False);
end;

robert - i am one of the people that sent you code - i was the one who wrote
and sent you TShutDownEX - it will work on 98,95,NT
