How To Add User's GUID To An Account Verification E-mail
 

Hi everyone,
So I have a problem that is more difficult that it might seem at first
glance. created. Any help/a clever "duh" answer would be great as we've
spent more than 8 hours trying to get this working.

Please see the following thread for the full details:

"How To Add User's GUID To An Account Verification E-mail - E-mail Working,
Error In Retreiving GUID"

http://forums.asp.net/p/1172523

----
am receiving an error when I try to retrieve a newly (and
successfully...checked the DB) registered users GUID to include in an account
verification e-mail. I am using the e-mail that is sent by the membership
provider, however I am adding an extra step for the user to verify their
account. The e-mail works fine as long as I don't try and use the user's
GUID. The verification of a user's account step uses a newly defined
placeholder (<% Username %> and <% Password %> are supported by default in
asp.net membership) in the .txt file that is the basis for the e-mail. I can
get the placeholder to replace fine in the e-mail, however I get an error
when I try to include the user's GUID in the e-mail.

Here are examples:

Any help with fixing the error is appreciated. Thanks!

It means your GUID is null, try to check it before making a call.

Re: How To Add User's GUID To An Account Verification E-mail
 

Yes, Membership.Getuser says the user is null, but it is not. If I set a
break point before I call Membership.GetUser in the CreatedUser event of the
CreateNewUserWizard or even inthe SendingMil event which fires after
CreatedUser then I can manully check the DB and see all of the user's details
saved.

What line is #81?

RE: How To Add User's GUID To An Account Verification E-mail
 

Finally, determined the cause of the error. The DB had two application IDs
while I specified the applicationName in the membership provider, I needed to
specify the applicationName that I was looking for users in.
