本文以一个实例形式介绍了VC++简单实现关机、重启计算机的方法，代码比较实用，有一定的参考价值。完整实例代码如下：
void CWebBrowserView::OnMenuShutdown()
{
// TODO: 在此添加命令处理程序代码
if (AfxMessageBox("确定要关机吗？",MB_YESNO) == IDYES)
{
HANDLE hToken;
TOKEN_PRIVILEGES tkp;
// Get a token for this process.
if (!OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken))
{
AfxMessageBox("OpenProcessToken Error!");
return;
}
// 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, sizeof(TOKEN_PRIVILEGES), (PTOKEN_PRIVILEGES)NULL, NULL);
if (GetLastError() != ERROR_SUCCESS)
{
AfxMessageBox("关机失败");
return;
}
// Shut down the system and force all applications to close.
ExitWindowsEx(EWX_SHUTDOWN | EWX_FORCE, 0); //重启只需要把EWX_SHUTDOWN改为EWX_REBOOT
}
}
