這是VB Timer 的小測試

Public Class Form1
    Dim aa As Boolean
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Timer1.Enabled = True
        Timer1.Interval = 10
        aa = True
    End Sub

    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        If aa = True Then
            Label1.Left -= 1
            If Label1.Left <= 0 Then
                aa = False
            End If
        Else
            Label1.Left += 1
            If Label1.Left + Label1.Width >= Me.Width Then
                aa = True
            End If
        End If
    End Sub

    Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
