为什么不停止？

Question

我正在尝试制作视图机器人。仅供娱乐/个人使用。问题是我试图这样做，所以它一次只能打开20个窗口。它不会出于某种原因。我还希望它在关闭它生成的进程并进入循环之前等待2000毫秒。我把co1unt作为整数。有人帮忙吗？

Dim Co1unt As Integer = 0
Public Sub Refreshlist()
    Dim p As Process, co1unt As Integer, MyProgram As String = "iexplore"
    For Each p In Process.GetProcesses
        If p.ProcessName = MyProgram Then
            co1unt = co1unt + 1
            TextBox1.Text = co1unt
        End If
    Next
End Sub

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    Refreshlist()
    Do
        Refreshlist()
        If Co1unt < 20 Then
            Dim webAddress As String = ""
            Dim p1 As Process = Process.Start(webAddress)
            System.Threading.Thread.Sleep(2000)
            p1.Kill()
        End If
    Loop

End Sub
