Ciao Aniello.
Prova con questo codice:
Private tmr As Timer
Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
tmr = New Timer
AddHandler tmr.Tick, AddressOf tmr_tick
tmr.Interval = 1000
tmr.Enabled = True
tmr.Start()
End Sub
Private Sub tmr_tick(sender As Object, e As EventArgs)
'TODO: Codice di getione delle palline
End Sub
Facci sapere....
Ciao
