自动注销 [英] Auto Log-off

问题描述

我希望系统在闲置10分钟后自动注销用户.如何在vb.net中做到这一点?.桌面应用程序

我正在使用此代码:

I want my system to automatically log off user after may 10 minutes of being idle. How do I do that in vb.net?.Desktop application

Am Using this code:

Private Declare Function GetLastInputInfo Lib "user32" (ByRef plii As LASTINPUTINFO) As Boolean
    Private Declare Function GetTickCount Lib "kernel32" () As Int32
    Private Sub frmAutoLogout_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim tim As New Timer
        tim.Interval = 200
        AddHandler tim.Tick, AddressOf tim_Tick
        tim.Start()
    End Sub
    Private Sub tim_Tick(ByVal sender As Object, ByVal e As EventArgs)
        Dim lii As LASTINPUTINFO
        lii.cbSize = Len(lii)
        GetLastInputInfo(lii)
        lblCountdown.Text = "You have (secs): " & ((GetTickCount() - lii.dwTime) / 1000.0).ToString
    End Sub
End Class

但是我面临的挑战是检查Windows Idle而不是我的应用程序空闲.

But the challenge i have it is checking the Windows Idle lather than the my application idle.

推荐答案

要注销:

http://pinvoke.net/default.aspx/user32.ExitWindowsEx [ http://pinvoke.net/default.aspx/user32.GetLastInputInfo# [ Windows API:学习-直播 [ ^ ]

最后，谷歌是您的朋友.

To logoff:

http://pinvoke.net/default.aspx/user32.ExitWindowsEx[^]

To detect last windows activity:

http://pinvoke.net/default.aspx/user32.GetLastInputInfo#[^]

A tip I wrote:

The Windows API: Learn It - Live It[^]

And finally, google is your friend.

如果您希望它作为系统中的后台服务运行，则可以编写Windows Service来实现.我不知道如何检测用户是在使用系统还是在闲置.

If you want this to run as a background service in the system, you can perhaps write a Windows Service to achieve this. How to detect whether the user is using the system, or whether it is idle, I do not know.
