[VB.NET] Simulare dei clic e uso del threading

[oregon]

Dovrebbe essere

Dim Thread1 As System.Threading.Thread

e poi

Public Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
  Thread1 = New System.Threading.Thread(AddressOf clicca)
  Thread1.Start()
End Sub
