Windows – CPU power management APIs 3个
我正在开发一个C#WPF应用程序,该应用程序将安装在连接了APC 1500 UPS的Windows 7机器上.在断电时,我需要应用程序在Windows 7关闭之前响应某些关闭活动.
我正在开发一个C#WPF应用程序,该应用程序将安装在连接了APC 1500 UPS的Windows 7机器上.在断电时,我需要应用程序在Windows 7关闭之前响应某些关闭活动.
我可以直接处理Windows事件,还是需要与APC软件进行交互？如果是Windows,会发生什么事？任何链接或信息将不胜感激 – 我只是在搜索时没有看到太多.
谢谢.
解决方法
也许这有用吗？
private ManagementEventWatcher managementEventWatcher;
private readonly Dictionary<string,string> powerValues = new Dictionary<string,string>
{
{"4","Entering Suspend"},{"7","Resume from Suspend"},{"10","Power Status Change"},{"11","OEM Event"},{"18","Resume Automatic"}
};
public void InitPowerEvents()
{
var q = new WqlEventQuery();
var scope = new ManagementScope("root\\CIMV2");
q.EventClassName = "Win32_PowerManagementEvent";
managementEventWatcher = new ManagementEventWatcher(scope,q);
managementEventWatcher.EventArrived += PowerEventArrive;
managementEventWatcher.Start();
}
private void PowerEventArrive(object sender,EventArrivedEventArgs e)
{
foreach (PropertyData pd in e.NewEvent.Properties)
{
if (pd == null || pd.Value == null) continue;
var name = powerValues.ContainsKey(pd.Value.ToString())
? powerValues[pd.Value.ToString()]
: pd.Value.ToString();
Console.WriteLine("PowerEvent:"+name);
}
}
public void Stop()
{
managementEventWatcher.Stop();
}
