Can't Connect to SQL db

[DanWeaver]

Going a bit crazy. Have sqlserver all installed and running. I have a
security problem I think- have read many other news posts that SOUND
similar but e.g. My SQL Server configuration manager doesnt seem to
have seccurity options let alone offer the possibility of allowing a
'mix' of SQL/ windows requests.

For logon in SQL Server configuration manager 'built- in account'
local system is selected rather than the 'this account' option which
has stars in the password field and no username options.

This is myconnection string: kris\ is this local machine

myConnection = New SqlConnection("server=kris
\SQLEXPRESS;uid=sa;pwd=;database=pubs")

This is the error I get
System.Data.SqlClient.SqlException was unhandled
Class=14
ErrorCode=-2146232060
LineNumber=65536
Message="Login failed for user 'sa'. The user is not associated with
a trusted SQL Server connection."
Number=18452
Procedure=""
Server="kris\SQLEXPRESS"

Any ideas?

Have you enabled you server for SQL authetnication? By default,
SQL Server permits only Window authentication.

Do you have any particular reason you want to use SQL authentication?
Else, change "uid=sa;pwd=" to "Integrated Security=SSPI".

For logon in SQL Server configuration manager 'built- in account'
local system is selected rather than the 'this account' option which
has stars in the password field and no username options.

Note that his is about how SQL Server logs into Windows. That's a
different thing.

Thanks, Erland. That helped move me on- in fact the first time I tried
it it seemed to work (though my record was not added- posibly as there
already existed a record with same id) Anyway- I cant experiment with
that cos shorlty after I could no longer connect- seems strange- I
checked the table after first successful run to see if it had updated
and ran the code again- got a message "another process is locking the
db"- great I thought- all is working- and closed the connection in
VS-
now though the connection gets stuck at login and says:

Cannot open database "pubs" requested by the login. The login failed.
Login failed for user 'KRISLAPTOP\Kris'.

Seems like that either your user is not present in the pubs database,
or the database has somehow gone away.

Thanks, Erland. Something fishy was ocurring with the dbs- deleted
them and reconnected and set permissions again- seems to work now.

Cheers, more challenging questions (when I am more informed!) will
probably follow.
