Success - Shutdown Windows, in C++ with ExitWindowsEx

以下是Code:

// shutdown.cpp : main project file.

#include "stdafx.h"

using namespace System;
using namespace System::Runtime::InteropServices;


[DllImport("kernel32.dll")]
extern "C" int* GetCurrentProcess(void);

[DllImport("advapi32.dll")]
extern "C" int OpenProcessToken(int* ProcessHandle,unsigned long DesireAccess, int** TokenHandle);

typedef struct _LUID {
unsigned long LowPart;
long          HighPart;
} LUID, *PLUID;

[DllImport("advapi32.dll")]
extern "C" int LookupPrivilegeValue(char* lpSystemName, char* lpName, PLUID lpLuid);

typedef struct _LUID_AND_ATTRIBUTES {
LUID Luid;
unsigned long Attributes;
} LUID_AND_ATTRIBUTES, *PLUID_AND_ATTRIBUTES;

typedef struct _TOKEN_PRIVILEGES {
unsigned long PrivliegeCount;
LUID_AND_ATTRIBUTES Privileges[1];
} TOKEN_PRIVILEGES, *PTOKEN_PRIVILEGES;

[DllImport("advapi32.dll")]
extern "C" int AdjustTokenPrivileges(int* TokenHandle, int DisableAllPriviliges, PTOKEN_PRIVILEGES NewState,
                                 unsigned long BufferLength, PTOKEN_PRIVILEGES PreviousState,
                                 unsigned long ReturnLength);

[DllImport("kernel32.dll")]
extern "C" unsigned long GetLastError(void);

[DllImport("user32.dll")]
extern "C" int ExitWindowsEx(unsigned int uFlags, unsigned long dwReason);

const int SE_PRIVILEGE_ENABLED    = 0x00000002;

const int TOKEN_ADJUST_PRIVILEGES = 0x00000020;
char *SE_SHUTDOWN_NAME      = "SeShutdownPrivilege";

const int EWX_LOGOFF              = 0x00000000;
const int EWX_SHUTDOWN            = 0x00000001;
const int EWX_REBOOT              = 0x00000002;
const int EWX_FORCE               = 0x00000004;

const int EWX_FORCEIFHUNG         = 0x00000010;


int main(array<System::String ^> ^args)
{
int* hToken;
TOKEN_PRIVILEGES tkp;


if( !OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken) ) {
    Console::WriteLine(L"Failed!!\n");
    return 0;
}

LookupPrivilegeValue(0,SE_SHUTDOWN_NAME, &tkp.Privileges[0].Luid);

tkp.PrivliegeCount = 1;
tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;

AdjustTokenPrivileges(hToken, 0, &tkp, 0, (PTOKEN_PRIVILEGES)0, 0);

if(GetLastError() != 0){
    Console::WriteLine(L"Error!\n");
    return 0;
}

if(!ExitWindowsEx(1,0)){
    Console::WriteLine(L"ExitFail\n");
    return 0;
}



Console::WriteLine(L"Hello World");
return 0;
}

執行後就會關機了，但是power不會off，會到..."現在可以自行關機了..."

不知道是甚麼問題....是不是argument 沒有加上 POWEROFF - 0x08 ?

的確，ExitWindowsEx 的argument使用

EWX_SHUTDOWN | EWX_FORCE | EWX_POWEROFF

就會自動poweroff了
