I'm trying to get to grips with ado.net under vb.net. Below I've included a rather simple piece of code which is producing a run time error on line 18. The error message produced is.

"An unhandled exception of type 'System.Data.SqlClient.SqlException' occurred in microsoft.visualbasic.dll

Additional information: System error."

Imports System
Imports System.Data
Imports System.Data.SqlClient

Module Module1

    Sub Main()

        Dim Conn = New SqlConnection("Data Source=P2000;Initial Catalog=Northwind;Integrated Security=SSPI")
        Dim rdr As SqlDataReader

        Conn.open()

        Dim cmd = New SqlCommand("select * from cutomers", Conn)



        rdr = cmd.ExecuteReader()

    End Sub

End Module

Sorry left the line numbers off!!

Line 18 is:

 rdr = cmd.ExecuteReader()

Thanks

Found the answer. It was deeply technical !!!

I spell "Customers" wrong!!!
