I tried in this way. I subscribed to that event who control the user status, its announcing me that user in Online. my code is:
void Nameserver_ContactOnline(object sender, ContactEventArgs e)
{
Talk = messenger.CreateConversation();
Talk.Invite(e.Contact.Mail,ClientType.PassportMember);
Talk.SendTextMessage(new TextMessage(Msg));
Talk.End();
LogEvent("Contact online " + e.Contact.Name.ToString() + " " + e.Contact.Mail.ToString());
}
someone can give me a hint ? maybe i do something wrong because message wasn't sent. thanks.
