Hi Pavel.
Sorry, but I'm brand new to this .NET and DNP API stuff, so I'm not really sure what you're asking.
The DNP API code was written by somebody else, but if you tell me exactly what you're looking for I'll find it. It will be a big help if you could give me a keyword that I could search for in the code.
Is this code snippet of any use to you:
Public Function Activate(ByVal Domainname As String, ByVal FirstName As String, ByVal Lastname As String, ByVal Password As String _
, ByVal UserEmail As String, ByVal Email1 As String, ByVal Email1Password As String, ByVal Email2 As String _
, ByVal Email2Password As String, ByVal Email3 As String, ByVal Email3Password As String, ByVal Email4 As String _
, ByVal Email4Password As String, ByVal Email5 As String, ByVal Email5Password As String) As Result
