VC++简单实现关机、重启计算机实例代码

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
 }
}
