'In a Module..
Private Declare Function RegOpenKey Lib "advapi32.dll" Alias "RegOpenKeyA" (ByVal hKey As Long, ByVal lpSubKey As String, phkResult As Long) As Long
Private Declare Function RegQueryValueEx Lib "advapi32.dll" Alias "RegQueryValueExA" (ByVal hKey As Long, ByVal lpValueName As String, ByVal lpReserved As Long, lpType As Long, lpData As Any, lpcbData As Long) As Long ' Note that if you declare the lpData parameter as string, you must pass it By Value.
Private Declare Function RegCloseKey Lib "advapi32.dll" (ByVal hKey As Long) As Long
Private Const HKEY_LOCAL_MACHINE = &H80000002

Public Function IsConnected() As Boolean
Dim lRegKey As Long
Dim bData(3) As Byte

If RegOpenKey(HKEY_LOCAL_MACHINE, "System\CurrentControlSet\Services\RemoteAccess", lRegKey) = 0 Then
'Opened RegKey Successfully..
If RegQueryValueEx(lRegKey, "Remote Connection", 0&, 1&, bData(0), 4) = 0 Then
'Query the Value of "Remote Connection" 1 - Connected, 0 - Not Connected
IsConnected = bData(0)
Else
'Counldn't find the Value, assume no Connection
IsConnected = False
End If
'Close the Registry Key
Call RegCloseKey(lRegKey)
End If
End Function


This proc will tell you if you are connected to the internet. Create a loop and check when connection is established
