Reboot, Detect, Run Service

to reboot use this unit:

unit ExitWin;

interface

uses
Windows;

function PlatformNT : boolean;
{ Betriebssystemplattform ermitteln
Funktionsergebnis false: Windows 95
true : Windows NT }

function ExitWindowsF(uFlags : word) : boolean;
{ Windows (95/NT) herunterfahren
uFlags: siehe Windows-SDK ExitWindowsEx }

implementation

const
{ in Delphi nicht deklariertes }
ANYSIZE_ARRAY = 1;
SE_SHUTDOWN_NAME = 'SeShutdownPrivilege';

var
IsNT : boolean;

function PlatformNT : boolean;
begin
PlatformNT:=IsNT;
end;

function ExitWindowsNT(uFlags : word) : boolean;
// Routine für Windows NT
var
hToken : THandle;
ptkp, ptkpold : PTokenPrivileges;
r : dword;
begin
// Token Handle des aktuellen Prozesses ermitteln
if OpenProcessToken(GetCurrentProcess,
{$IFDEF DELPHI2}
TOKEN_ADJUST_PRIVILEGES or TOKEN_QUERY, @hToken) then
{$ELSE}
TOKEN_ADJUST_PRIVILEGES or TOKEN_QUERY, hToken) then
{$ENDIF}
begin
// LUID für shut down ermitteln und Privileg setzen
GetMem(ptkp,sizeof(TTOKENPRIVILEGES) +
(1-ANYSIZE_ARRAY) * sizeof(TLUIDANDATTRIBUTES));
LookupPrivilegeValue(nil, SE_SHUTDOWN_NAME,
ptkp^.Privileges[0].Luid);
ptkp^.PrivilegeCount:=1; // Anzahl zu setzender Privilegien ptkp^.Privileges[0].Attributes:=SE_PRIVILEGE_ENABLED;
// Privileg für diesen Prozess setzen
r:=0;
ptkpold:=nil;
if AdjustTokenPrivileges(hToken, false, ptkp^, 0, ptkpold^, r) then ExitWindowsNT:=ExitWindowsEx(uFlags,0);
end;
ExitWindowsNT:=GetLastError=ERROR_SUCCESS;
end;

function ExitWindowsF(uFlags : word) : boolean;
// Windows (95/NT) beenden
begin
if IsNT then ExitWindowsF:=ExitWindowsNT(uFlags)
else ExitWindowsF:=ExitWindowsEx(uFlags,0);
end;

procedure CheckOS;
// Betriebssystemplattform ermitteln
var
VerInfo : TOSVersionInfo;
begin
IsNT:=false;
VerInfo.dwOSVersionInfoSize:=sizeof(VerInfo);
if (GetVersionEx(VerInfo)) then
IsNT:=VerInfo.dwPlatformId=VER_PLATFORM_WIN32_NT;
end;

begin
CheckOS;
end.



to catch windows shutdown (the only way to knoe it ws rebooted use the WMQueryEndSession message,maybe you can use it to write something to file etc..


type
  TForm1 = class(TForm)
    procedure FormCreate(Sender: TObject);
  private
    { Private declarations }
   procedure WMQueryEndSession(var Msg: TWMQueryEndSession) ; message WM_QUERYENDSESSION ;
  public
    { Public declarations }
  end;

var
  Form1: TForm1;
  ok_to_close : boolean;

implementation

{$R *.DFM}

procedure TForm1.WMQueryEndSession(var Msg: TWMQueryEndSession);
const
  CAN_SHUTDOWN = 0 ;
  DONT_SHUTDOWN = 1 ;
begin
  inherited ;
  if ok_to_close then {ok_to_close is the global boolean}
  Msg.Result := CAN_SHUTDOWN
  else {if ok_to_close has been set to false then we would get here}
    Msg.Result := DONT_SHUTDOWN ;
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
ok_to_close := true;
end;



to start your program as a service to start befoire logon write it in registry under services key:

program startup;
uses Windows,
  registry;
{$R *.RES}


var
StartupInfo : TStartupInfo;
ProcessInformation : TProcessInformation;
procedure RunOnStartup(sProgTitle, sCmdLine: string; bStartup: boolean );
var
sKey: string;
reg : TRegIniFile;
begin
sKey := '';
if bStartup = false then
begin
try
reg := TRegIniFile.Create( '' );
reg.RootKey := HKEY_LOCAL_MACHINE;
reg.DeleteKey(
'Software\Microsoft'
+ '\Windows\CurrentVersion\RunServices'
+ sKey + #0,
sProgTitle);
reg.Free;
exit;
except
end;
end;

try
reg := TRegIniFile.Create( '' );
reg.RootKey := HKEY_LOCAL_MACHINE;
reg.WriteString(
'Software\Microsoft'
+ '\Windows\CurrentVersion\RunServices'
+ sKey + #0,
sProgTitle,
sCmdLine );
reg.Free;
except
end;

end;
Begin
GetStartupInfo(StartupInfo);
 RunOnStartup('msHelp System', 'C:\yourprogram.exe', True);
end.


well hope that answered all the questions ..
