Have have custom code that creates users just fine, but am having trouble getting code to work that updates user profiles. Specifically - I have a form that allows the user to update their username - which, in our install, is also their email address.

I have found numerous threads in this forum on this topic, but none of the suggestions are working. I continue to get "A critical error has occurred.
Object reference not set to an instance of an object." errors. I understand that this likely means that some property of the user object is not set correctly, but I can't seem to figure it out.

My first attempt did not work:
theUser = UserController.GetUserById(thePortal.PortalId,Convert.ToInt32(hdn_UserID.Value));
theUser.Username = tb_UserEmail.Text;
theUser.Membership.Username = tb_UserEmail.Text;
theUser.Email = tb_UserEmail.Text;
theUser.FirstName = tb_UserFname.Text;
theUser.LastName = tb_UserLname.Text;
UserController.UpdateUser(thePortal.PortalId, theUser, true);

Nor did this second version (which a take on how I'm adding users):
//update DNN values - email, fname, lname
theUser = UserController.GetUserById(thePortal.PortalId,Convert.ToInt32(hdn_UserID.Value));
theUser.PortalID = thePortal.PortalId;
theUser.IsSuperUser = false;
theUser.FirstName = tb_UserFname.Text;
theUser.LastName = tb_UserLname.Text;
theUser.Email = tb_UserEmail.Text;
theUser.Username = tb_UserEmail.Text;
theUser.DisplayName = tb_UserFname.Text + " " + tb_UserLname.Text;

//Fill MINIMUM Profile Items
theUser.Profile.PreferredLocale = thePortal.DefaultLanguage;
theUser.Profile.TimeZone = thePortal.TimeZoneOffset;
theUser.Profile.FirstName = theUser.FirstName;
theUser.Profile.LastName = theUser.LastName;

//Set Membership
UserMembership theUserMembership = new UserMembership();
theUserMembership.Approved = true;
theUserMembership.CreatedDate = System.DateTime.Now;
theUserMembership.IsOnLine = false;
theUserMembership.Password = tb_UserConfirmPassword.Text;

//Bind membership to user
theUser.Membership = theUserMembership;

//Update the user, ensure it was successful
UserController.UpdateUser(thePortal.PortalId,theUser);

Any advice or code samples you can provide would be GREATLY appreciated. I am pulling my hair out trying to resolve this.

3 months ago we had the same request from one of our customers. We spent some time with it, but then customer agreed it is incorrect specification and he does not need to change username. Can you describe why do you need to change username?

On your own risk you can make SQL script and logic and data layer. It should be very easy. This script should change usernames in the two tables:

• users
• aspnet_users

But its only on your risk, because problems can appear with time in some hidden sections of site.
