Is there a command(s) which can tell me if I'm still connected to the internet or disconnected? I don't want to check the "state" method in a repeating loop after a connect call and wait for an error to occur to tell if its been disconnected. What I want to know is if Im already connected to the net and am trasnfering something via the winsock control and then all of a sudden i get disconnected is there a function to let me know when this disconnection happens?

No..you need a timer with this code. There is no other way unless theres an API I don't know about, but since the winsock control is just a wrapper for wsock32.dll, I doubt it.

Private Sub Timer1_Timer()
  Select Case svrsock.State
Case 0
    Me.Caption = "Closed"
Case 1
    Me.Caption = "Open"
Case 2
    Me.Caption = "Listening"
Case 3
    Me.Caption = "Connection pending"
Case 4
    Me.Caption = "Resolving host"
Case 5
    Me.Caption = "Host resolved"
Case 6
    Me.Caption = "Connecting"
Case 7
    Me.Caption = "Connected"
Case 8
    Me.Caption = "Peer is closing the connection"
Case 9
    Me.Caption = "Error"
End Select
End Sub
