Ciao ragazzi.. mi chiamo Alessandro, ho 22 anni e faccio il programmatore cobol (purtroppo alle superiori ci hanno insegnato solo quello).

Mi sto cimentando in VB.net e avrei bisogno di una mano:
In pratica sto cercando di creare un programma che fa degli screenshoot ogni "n" secondi e li salva .. solo che non riesco a capire perche, dopo il primo screen si ferma come se uscisse dal ciclo del "tick".

questo è il codice :

codice:
Public Class Form1 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 
End Sub 

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click 
   Button1.Visible = False 
   Button2.Visible = True 
   Me.Timer1.Interval = 1000
   Me.Timer1.Enabled = True 
   Me.Timer1.Start() 
End Sub

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click 

   Button2.Text = "Stopped" 
   Me.Timer1.Enabled = False 
End Sub 

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick 

   Dim bounds As Rectangle 
   Dim Screenshot As System.Drawing.Bitmap 
   Dim graph As Graphics bounds = Screen.PrimaryScreen.Bounds 
   Screenshot = New System.Drawing.Bitmap(bounds.Width, bounds.Height, System.Drawing.Imaging.PixelFormat.Format32bppArgb)  
   graph = Graphics.FromImage(Screenshot) graph.CopyFromScreen(bounds.X, bounds.Y, 0, 0, bounds.Size, CopyPixelOperation.SourceCopy) 
   PictureBox1.Image = Screenshot 
   Timer1.Enabled = False 
   Dim b As Integer 
   Dim c As String 
   b = b + 1 
   c = "C:\Users\Michael Scofield\Desktop\" & b & ".jpg" 
   PictureBox1.Image.Save(c, System.Drawing.Imaging.ImageFormat.Bmp) 
End Sub 
End Class
chi mi da una mano??

Grazie..
