Connect with SQL Server 2008 Express using Winforms (C#)

Question

I am creating the database from coding in Winforms (C#) and also run the script for creating the tables.

In short I create the database using the Winforms (C#) in SQL Server Express.

But when I run my application I get this error :

Cannot open database '' requested by the login. the login failed. login failed for user 'KETAN\\admin'.

My connection string:

Server=.\SQLEXPRESS;Integrated Security=True;database=mydatabasename;User Id=myusername;Password=mypassword;

Any help would be appreciated.

Answer 1

If you have both

Integrated Security=True;

and

User Id=myusername;Password=mypassword;

in your connection string, then the Integrated Security wins and the specific user and password are ignored , and the connection is attempted with your current Windows credentials ( KETAN\\admin ) and that doesn't seem to work

So just change your connection string to:

Server=.\SQLEXPRESS;database=mydatabasename;User Id=myusername;Password=mypassword;

Now, your specific user and its password will be used to connect to SQL Server, and if those are correct, you should be able to connect just fine
