使用计时器检测应用中的空闲时间的问题

问题描述

我有一个应用程序.在此应用程序中，我要关闭该应用程序&如果用户闲置5分钟，则激活登录表单.
为了这个目的，我使用了计时器.但是通过这种方式，我必须对每种形式的应用程序都使用计时器.
有什么办法可以使用一个计时器来完成整个应用程序?
请不要建议我在新表单中添加计时器，并使用每个表单调用该表单，
因为我尝试过，这是一种错误的方式，并且无法真正起作用.

谢谢alot

推荐答案

Partial Friend Class MyApplication

    Public WithEvents idleTimer As Timer

    Private Sub MyApplication_Startup(sender As Object, e As Microsoft.VisualBasic.ApplicationServices.StartupEventArgs) Handles Me.Startup
        idleTimer = New Timer
        idleTimer.Interval = 5 * 60 * 1000 '(300,000mseconds = 5 minutes)

        idleTimer.Start() 'start the timer

    End Sub

    Private Sub idleTimer_Tick() Handles idleTimer.Tick
        'Do what ever you need to when it times out
    End Sub

End Class

您只需要确保任何用户交互，打开表单，按键，单击按钮等，重置计时器即可.

You just need to make sure that any user interaction, opening forms, keypresses, button clicks etc, reset the timer
