Hello Everybody!

I'm working on my custom registration interface and having a problem with it. I'm able to create new user by performing code like this :

        UserInfo user = new UserInfo();
        user.Username = txtUserName.Value.Trim();
        user.PortalID = PortalId;
        user.FirstName = txtFirstName.Value.Trim();
        user.LastName = txtLastName.Value.Trim();
        user.Membership.Username = txtUserName.Value.Trim();
        user.Membership.UpdatePassword = false;
        user.Membership.Password = txtPassword.Value;
        user.LastName = txtLastName.Value.Trim();
        user.IsSuperUser = false;
        user.Email = txtEmail.Value.Trim();
        user.DisplayName = txtFirstName.Value.Trim() + " " + txtLastName.Value.Trim();
       
        MembershipProvider.Instance().CreateUser(ref user);

Everything's going smoothly with this code, but I can't understand what else I should do to get user logged in after this process. I simply want user not to need passing login procedure just after he's done with registration.

That will be nice if somebody has idea about how to figure this out.

Thanks in advance!
