I'm trying to SCONNECT a SQL server database (in this case, an instance of SQL 
Express running on the same laptop, but I don't think that matters).
I would like to use Windows Authentication (and not provide a user name and 
password).  I can do this successfully by using the connection string:
sconnect ';driver=SQL Server Native Client 
11.0;server=LARRY-LUSTIG-ZN\SQLExpress;database=MyDatabase;'

and then checking the Trusted Connection checkbox on the SQL Server Connection 
dialog that is displayed by the SQL Server driver.
I would like to do this without have to see the Connect dialog box.  I have 
tried the following additions to the connection string:
Trusted_Connection=True;Trusted_Connection=1;Trusted_Connection=-1;Integrated 
Security=True;Integrated Security=SSPI;
but none have the effect I want.  When I use Trusted_Connection (with any 
value) I get an error message from the SQL Server client about a bad value for 
Trusted_Connection, if I use Integrated Security it's ignored and I see the 
dialog box.
Can anyone help my connect to my SQL Server using Windows Authentication 
without having to deal with the SQL Server client dialog?
