Access to SQL Express connection string

I need to hardcode my TCP port to a SQL Server Express named instance. You guys have any examples I could see. I keep getting an error when I try to connect:

Run-time error 2147467259 BBNETLIB connection open parse connection paramaters, invalid connection. I'm trying to connect to a local instance on a Windows 2003 server.

Please post your connection string.|||

CONNECTION=Provider=SQLOLEDB;Data Source=SQCTLxp1\C1SQLEXPRESS;User ID=sa;Password=!!Gulpp1!!;Initial Catalog=@.DBNAME;

I removed the semicolon at the end of the connection string and it worked. Thank You.
