如何检测Windows是关闭还是重新启动

restart shutdown api winapi c++

Andrew Garrison · 技术社区 · 17 年前

我知道当Windows关闭时,它会发送一个 WM_QUERYENDSESSION

考虑到MSDN的文档有这样的说法,我并不特别有希望 WM_QUERYENDSESSION

WM_ENDSESSION 并记录下来。现在记录时间。如果系统在合理的时间内(比如5分钟)恢复。那是重启,而不是关机。

想法真的

API hooking ExitWindowsEx 以及相关功能,但我不推荐这种方法。如果你真的需要直接检测到这一点,请重新思考。

Windows7的可能实验解决方案如下。(我不确定这是否适用于其他本地化,因此我称之为变通方法)

using System.Diagnostics.Eventing.Reader;

namespace MyApp
{
public class RestartDetector : IDisposable
{
    public delegate void OnShutdownRequsted(bool restart);
    public OnShutdownRequsted onShutdownRequsted;

    private EventLogWatcher watcher = null;

    public RestartDetector()
    {
        try
        {
            EventLogQuery subscriptionQuery = new EventLogQuery(
                "System", PathType.LogName, "*[System[Provider[@Name='USER32'] and (EventID=1074)]]");

            watcher = new EventLogWatcher(subscriptionQuery);

            // Make the watcher listen to the EventRecordWritten
            // events.  When this event happens, the callback method
            // (EventLogEventRead) is called.
            watcher.EventRecordWritten +=
                new EventHandler<EventRecordWrittenEventArgs>(
                    EventLogEventRead);

            // Activate the subscription
            watcher.Enabled = true;
        }
        catch (EventLogReadingException e)
        {
        }
    }

    public void EventLogEventRead(object obj, EventRecordWrittenEventArgs arg)
    {
        bool restart = false;
        try
        {
            // Make sure there was no error reading the event.
            if (arg.EventRecord != null)
            {
                String[] xPathRefs = new String[1];
                xPathRefs[0] = "Event/EventData/Data";
                IEnumerable<String> xPathEnum = xPathRefs;

                EventLogPropertySelector logPropertyContext = new EventLogPropertySelector(xPathEnum);
                IList<object> logEventProps = ((EventLogRecord)arg.EventRecord).GetPropertyValues(logPropertyContext);

                string[] eventData = (string[])logEventProps[0];

                foreach (string attribute in eventData)
                {
                    if (attribute.Contains("restart")) { restart = true; break; }
                }
            }
        }
        catch (Exception e)
        {
        }
        finally
        {
            if (onShutdownRequsted != null) { onShutdownRequsted(restart); }
        }   
    }

    public void Dispose()
    {
        // Stop listening to events
        if (watcher != null)
        {
            watcher.Enabled = false;
            watcher.Dispose();
        }
    }
}
}
