求指点，我新手！

我新手，刚学，代码编译有点简单，大家别笑我想弄个定时关机，下面是代码，可是当时间到的时候没反映，怎么回事
#include "stdafx.h"
#include "time.h"
#include <windows.h>
#include <windowsx.h>
#include "resource.h"
#include "MainDlg.h"


BOOL WINAPI Main_Proc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
switch(uMsg)
{
HANDLE_MSG(hWnd, WM_INITDIALOG, Main_OnInitDialog);
HANDLE_MSG(hWnd, WM_COMMAND, Main_OnCommand);
HANDLE_MSG(hWnd,WM_CLOSE, Main_OnClose);
}

return FALSE;
}
void CALLBACK TimerProc (HWND hwnd, UINT message, UINT iTimerID, DWORD dwTime)
{
SYSTEMTIME stLocal;
GetLocalTime(&stLocal);
TCHAR str1[256];
wsprintf(str1,TEXT("%u"),stLocal.wHour);
SetDlgItemText(hwnd,IDC_EDIT1,str1);
TCHAR str2[256];
wsprintf(str2,TEXT("%u"),stLocal.wMinute);
SetDlgItemText(hwnd,IDC_EDIT2,str2);
TCHAR str3[256];
wsprintf(str3,TEXT("%u"),stLocal.wSecond);
SetDlgItemText(hwnd,IDC_EDIT3,str3);

}

BOOL Main_OnInitDialog(HWND hwnd, HWND hwndFocus, LPARAM lParam)
{
SetTimer(hwnd,0,1000,TimerProc);

return TRUE;
}

void Main_OnCommand(HWND hwnd, int id, HWND hwndCtl, UINT codeNotify)
{
switch(id)
{
case IDC_OK:
{
SYSTEMTIME stLocal;
GetLocalTime(&stLocal);
TCHAR str1[256];
wsprintf(str1,TEXT("%u"),stLocal.wHour);
TCHAR str2[256];
wsprintf(str2,TEXT("%u"),stLocal.wMinute);
TCHAR str3[256];
wsprintf(str3,TEXT("%u"),stLocal.wSecond);
TCHAR str6[256];
GetDlgItemText(hwnd,IDC_EDIT6,str6,sizeof(str1));
TCHAR str7[256];
GetDlgItemText(hwnd,IDC_EDIT6,str7,sizeof(str7));
TCHAR str8[256];
GetDlgItemText(hwnd,IDC_EDIT8,str8,sizeof(str8));
if(str6==str1,str7==str2,str3==str8)
ExitWindowsEx(EWX_SHUTDOWN,4);






}
break;
default:
break;
}
}

void Main_OnClose(HWND hwnd)
{
EndDialog(hwnd, 0);
}

VC的程序?
在windows2000以上关机需要提升权限的
(当然前提是要超级用户权限)

HANDLE hToken; 
TOKEN_PRIVILEGES tkp,tkpNew; 
LUID int64LpUid; 

OpenProcessToken(GetCurrentProcess(),TOKEN_ADJUST_PRIVILEGES|TOKEN_QUERY,&hToken) 
LookupPrivilegeValue(NULL,"SeShutdownPrivilege",&int64LpUid); 
tkp.PrivilegeCount=1; 
tkp.Privileges[0].Liud=int64LpUid; 
tkp.Privileges[0].Attributes=SE_PRIVILEGE_ENABLED; 
AdjustTokenPrivileges(hToken,FALSE,&tkp,sizeof(tkp),&tkpNew,&dwSize); 

Windows NT/2000 关机函数 
BOOL MySystemShutdown() 
{ 
HANDLE hToken; 
TOKEN_PRIVILEGES tkp; 

// Get a token for this process. 

if (!OpenProcessToken(GetCurrentProcess(), 
TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken)) 
return( FALSE ); 

// Get the LUID for the shutdown privilege. 

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

tkp.PrivilegeCount = 1; // one privilege to set 
tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED; 

// Get the shutdown privilege for this process. 

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

if (GetLastError() != ERROR_SUCCESS) 
return FALSE; 

// Shut down the system and force all applications to close. 

if (!ExitWindowsEx(EWX_SHUTDOWN | EWX_FORCE, 0)) 
return FALSE; 

return TRUE; 
}
