Hi,
VS2013, VB, SQL Express MSSQL11
I've been accomplishing a pilot project to learn the details of VB.NET database application programming.
I needed to connect to a database through SQL EXPRESS.  My initial attempt to attach the .mdf failed due to permissions, which was expected, although I had forgotten about that :-(.  I set the .mdf's security tab to add the Windows user account I log on with.  I was able to attach the database and my pilot project proceeded just fine.
Later when looking at the security tab again I noticed the Windows user account had been removed, and MSSQL$SQLEXPRESS had appeared.
1) I would like to understand what happened
2) Should I have set the security tab using MSSQL$SQLEXPRESS to begin with
3) Can someone explain how to add MSSQL$SQLEXPRESS because it doesn't show up with a normal search in the security tab
Thanks so much.
Best Regards,
Alan
