推荐答案

这里是一个简单的例子:

here is a simple example:

Public Class SampleCallEveryXMinute

     Private WithEvents xTimer as new System.Windows.Forms.Timer

     Public Sub New(TickValue as integer)
         xTimer = new System.Windows.Forms.Timer
         xTimer.Interval = TickValue
     End Sub

     Public Sub StartTimer
         xTimer.Start
     End Sub

     Public Sub StopTimer
         xTimer.Stop
     End Sub

     Private Sub Timer_Tick Handles xTimer.Tick
         SampleProcedure
     End Sub

     Private Sub SampleProcedure
         'SomeCodesHERE
     End Sub

End Class

用法:

Dim xSub as new SampleCallEveryXMinute(60000) ' 1000 ms = 1 sec so 60000 ms = 1 min
xSub.StartTimer
