如何检测工作站锁 [英] How to detect a workstation lock

问题描述

我正在开发应用程序，并且试图检测工作站何时被锁定，例如通过用户按下Windows + L键.

I'm developing an application and I'm trying to detect when the workstation gets locked, for example by the user pressing the Windows + L keys.

我知道lock事件具有值

I know that the lock event has the value

  WTS_SESSION_LOCK 0x7

但是我不知道如何使用它.我已经在网上搜索了，但一无所获.

But i don't know how to use it. I've searched the web but found nothing.

推荐答案

最终在VB上成功做到了:D

Finnallly managed to do it on VB :D

首先，您需要导入库:

Imports System
Imports Microsoft.Win32
Imports System.Windows.Forms

然后添加处理程序:

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load

    AddHandler SystemEvents.SessionSwitch, AddressOf SessionSwitch_Event

End Sub

最后，创建捕获它的子项:

Finnally you create the sub that captures it:

Private Sub SessionSwitch_Event(ByVal sender As Object, ByVal e As SessionSwitchEventArgs)

    If e.Reason = SessionSwitchReason.SessionLock Then
        MsgBox("Locked")
    End If
    If e.Reason = SessionSwitchReason.SessionUnlock Then
        MsgBox("Unlocked")
    End If
End Sub

最后一次删除处理程序:

Last you remove the handler:

Private Sub closing_event(sender As Object, e As FormClosingEventArgs) Handles MyBase.FormClosing
    RemoveHandler SystemEvents.SessionSwitch, AddressOf SessionSwitch_Event
End Sub
