Hi,
Just after installing my application, I need to attach my DB to SQL server. I am using following code for it.

VB

Dim cmd As New SqlCommand()
       Dim vrMyConString As String = "Data Source=.\SQLExpress; INITIAL CATALOG=master; uid=sa; pwd=sa;"
       Dim conn As System.Data.SqlClient.SqlConnection = New SqlConnection(vrMyConString)
       cmd.CommandText = "sp_attach_db 'e:\dbTest.mdf', 'e:\dbTest.ldf'"
       ' conn.ConnectionString = "Data Source=.\SQLExpress; INITIAL CATALOG=master; uid=sa; pwd=sa;"
       conn.Open()
       cmd.CommandType = CommandType.StoredProcedure
       cmd.Connection = conn
       cmd.executenonquery()

It gives error on
cmd.executenonquery()
"Could not locate entry in sysdatabases for database 'sp_attach_db 'e:\dbTest'. No entry found with that name. Make sure that the name is entered correctly."

Please advise what do I need to do.
Thanks

Every time I have seen that error it has been correct. Make sure the connection string is right.

Could u kindly advise what could be wrong in the connections string. I am using Windows authentication mode and there is no password on it.

Password issue is resolved... Now it gives error on cmd.executenonquery()
Could not locate entry in sysdatabases for database 'sp_attach_db 'e:\dbTest'. No entry found with that name. Make sure that the name is entered correctly.

Have you tried this?

Connecting to a SQL Server Express Database[^]

I would try the following in that section and see if you get any errors.

Otherwise I would look at user security to make sure they have enough permissions and that you can manually connect to the installed SQL Express through management studio etc.
