How do I create a new user in SQL Server 2012 that I can use in a connection string?

问题

I wasn't sure if this was a SO or SU question.

I have freshly installed SQL Server 2012.

I have created a database.

I have a visual studio 2012 project, and I want to connect to the database using a connection string in my web config.

Since I only have two accounts (sa and my windows account) I want to create a new user that will only have access to this one database.

Google says, in SSMS, expand the database, right click Security and go to New User.

However, when I do this and try to create a user, I choose SQL user with login, enter a username and login name, and get the error:

'news_login' is not a valid login or you do not have permission

I've tried by logging into SSMS as 'sa', logging in as my windows account, and running SSMS with administrator permissions. I've tried a few different usernames, and to no avail.

I notice there is no password box, so I fear I am doing it all wrong. Any suggestions?

Before you add the user to the db, add the user to the server -- under the server, right click the security folder, and try it that way. Then you can grant permissions to the appropriate databases to that user

Here's SQL way of doing this:

CREATE LOGIN NewUser   
    WITH PASSWORD = '340$Uuxwp7Mcxo7Khy';  
GO  

  CREATE USER NewUser FOR LOGIN NewUser;  
GO

EDIT: As per comment by @bschipp

Another example that does not expire password would be following

CREATE LOGIN NewUser   
    WITH PASSWORD = 'Uuxwp7Mcxo7Khy$#' CHECK_EXPIRATION = OFF, CHECK_POLICY = OFF;
GO
    CREATE USER NewUser FOR LOGIN NewUser;  
GO

First create a global login under Security -> Logins

Then add the user for the selected database in Databases -> Database -> Security -> Users
