如何在vb.net中创建多个计时器处理程序 [英] How to create multiple timer handler in vb.net

问题描述

• 我必须用处理程序创建多个定时器n次。


• 将在我的DataGrid中存储一行。


• 对于每一行，都会有一个计时器可以分开工作。

看起来像：

Private Sub CreateTimer()
    Dim tmr As New Timer
    tmr.Interval = 1000 '1 Second
    tmr.Enabled = True
    AddHandler tmr.Tick, AddressOf GlobalTimerTick
End Sub

'A timer tick handler that would work for each timer I add with the sub above
'All timers I created should work seperately
Private Sub GlobalTimerTick(TheTimer as Timer, ByVal sender As Object, ByVal e As EventArgs)
    mynumber = mynumber + 1
    With DataGridView1
        .Rows(n).Cells(4).Value = mynumber " saniye"
    End With
End Sub

那么我该如何实现呢？

推荐答案

code>标签属性的Timer将在您的案例中精美地工作。我目前没有我的IDE，但下面的代码段应该给你的想法。

I believe Tag property of Timer would work beautifully in your case. I don't have my IDE currently, but the following snippet should give you the idea.

Private Sub CreateTimer()
    Dim tmr As New Timer
    tmr.Interval = 1000 '1 Second
    tmr.Enabled = True
    tmr.Tag = ROW_INDEX
    AddHandler tmr.Tick, AddressOf GlobalTimerTick
End Sub

'A timer tick handler that would work for each timer I add with the sub above
'All timers I created should work seperately
Private Sub GlobalTimerTick(ByVal sender As Object, ByVal e As EventArgs)
    mynumber = sender.Tag
    With DataGridView1
        .Rows(n).Cells(4).Value = mynumber " saniye"
    End With
End Sub
