That's what addhandler and withevents created for .

Here's an example , that uses the power of addhandler method : Addhandler can fires one or multiple events or methods at the same time . This is also called delegates. This creates new timer control and you can manage its events at runtime.

Dim WithEvents TimerEvent As Timer
    Dim timr As New Timer()
    
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        timr.Interval = 2000
        timr.Enabled = True
    End Sub
 
    Private Sub FireTimer(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TimerEvent.Tick
        MsgBox("Hey there")
    End Sub
 
    Private Sub StopTimer()
        timr.Enabled = False
    End Sub
 
    Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
        AddHandler timr.Tick, AddressOf FireTimer
    End Sub
 
    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        timr.Enabled = False
    End Sub
