Cannot open database "dbname" requested by the login. The login failed

I'm trying to make a connection to sql server database(hosted on localhost) but keep getting the error mentioned in the title.

    Application("ConnectionString") = "Provider=SQLOLEDB;Data Source=localhost\SQLExpress;Database=mydb;Trusted_Connection=yes;UID=dbadmin; PWD=dbadmin" 
Application("ConnectionTimeout") = 15
Application("CommandTimeout") = 90
Application("CursorLocation") = 3

strQuery = "select * from dec_users"
Set objDBConnection = Server.CreateObject("ADODB.Connection")

objDBConnection.open Application("ConnectionString")
Set RS = Server.CreateObject("ADODB.RecordSet")

RS.Open strQuery, objDBConnection

any ideas?

You are putting it wrong, change to:

Application("ConnectionString") = "Provider=SQLOLEDB.1;Integrated Security=SSPI;
        Persist Security Info=False;User ID=dbadmin;Initial Catalog=mydb;
        Data Source=localhost\SQLExpress;Password=dbadmin"

(Linebreaks added for legibility)

When in doubt, create a .UDL file, construct the ConnectionString using the GUI, and then copy paste the ConnectionString (opening the file with notepad)
