在vb.net中设置超时

问题描述

我正处于中间状态，我需要设置一些超时以在超时中止一个线程。我需要的是一种方法，我可以设置一个超时的回调函数或子超时指定的超时时间将被调用。



这是一个示例使事情更清晰的代码

Hi, i am in the middle of something and i need to set some timeout to abort a thread in the timeout. What i need is a way i can set a timeout with a callback function or sub that will be called when the specified time of the timeout elapse.

Here is a sample code to make things more clearer

'here, i need to set a callback function that will be called when the time elapse.
Private Sub callbk()
    'code here will be executed when the time elapse
    Threading.Thread.Abort()
End Sub


Private Sub btn_start(ByVal sender As Object, ByVal e As System.EventArgs) Handles btn_start.Click
'setup a timeout here to call the sub callbk when the time elapse.
'for example, something like this
    myTimeout(5000, AddressOf callbk)
'the first argument is the time interval in milliseconds while the second argument is the function to callback after the period of 5 seconds
    While True
        'do some coding here that can never stop
        'so when the timeout elapse, the thread is aborted
        'by the callback function
    End While
End Sub

所以，我需要帮助！

推荐答案

'here, i need to set a callback function that will be called when the time elapse.
Private Sub callbk()
    'code here will be executed when the time elapse
    Threading.Thread.Abort()
End Sub


Private Sub btn_start(ByVal sender As Object, ByVal e As System.EventArgs) Handles btn_start.Click
'setup a timeout here to call the sub callbk when the time elapse.
'for example, something like this
    Dim tcb As TimerCallback = AddressOf callbk
    Dim t As Timer = New Timer(tcb, Nothing, 5000, -1)
'the first argument is the time interval in milliseconds while the second argument is the function to callback after the period of 5 seconds
    While True
        'do some coding here that can never stop
        'so when the timeout elapse, the thread is aborted
        'by the callback function
    End While
End Sub
