    Here's some quick example code:

          cmd AS New SqlCommand("SELECT * FROM Table WHERE ID= @ID", cn)
    
        cmd.Parameters.Add("@ID", SqlDbType.Int).Value = 12345
    
        cn.Open()
        Using rdr As SqlDataREader = cmd.ExecuteReader()
            While rdr.Read()
                'Do something with the record
            End While
            rdr.Close()
        End Using
    End Using
    

    Of course you need to Import System.Data and System.Data.SqlClient.
