VB.net SQL Timeout Expired

Hi. I am getting the following error
"The timeout period expired prior to completion of the operation or the server is not responding"
when I run the following code on view or table that has three million records.
Is there any way to extend the time before this errors out?

                sSQL = "SELECT Count(*) As MyCount FROM (" & oSQL & ") As X"

                Dim cn As New SqlConnection(oConnectionString)
                Dim cmd As New SqlCommand(sSQL, cn)
                cn.Open()

                Count_Rows_of_Query = cmd.ExecuteScalar.ToString

                If cn.State <> ConnectionState.Closed Then
                    cn.Close()
                End If

Add the ";Connection Timeout=60" to the oConnectionString where 60 is the number of seconds.
