Ti posto il codice:

Private Declare Auto Function GetPrivateProfileString Lib "kernel32.dll" _
(ByVal lpApplicationName As String, ByVal lpKeyName As String, ByVal lpDefault As String, _
ByVal lpReturnedString As String, ByVal nSize As Integer, ByVal lpFileName As String) As Integer


Sub ReadINI()

SourceFolder = My.Application.Info.DirectoryPath
CompletePath = SourceFolder & "\" & "config.ini"

sRetVal = GetPrivateProfileString("parametri", "DefaultPage", "", RtnStr, Len(RtnStr), CompletePath)
strHostName = System.Net.Dns.GetHostName()
strIPAddress = System.Net.Dns.GetHostEntry(strHostName).AddressLi st(0).ToString()
urlDefault = Trim(Left(RtnStr, sRetVal) + "?LocalIPAddress=" + strIPAddress + "&LocalHostName=" + strHostName)
MsgBox(urlDefault )

End sub


E' corretto???

Grazie
