SQL Get number of records affected in SQL Update

Hi
    I use several SQL update statements such the one below in my VB.net project.
    How do I get the number of records affected by each update statement?

     Dim sSQL As String

            sSQL = "Update [" & Me.lblCurrentTable.Text & "] Set Category1 = '" & Me.cmbCategory1.Text & "'"
            sSQL = sSQL & " Where [Product ID] = '" & oProductID & "'"

            Dim cn As New SqlConnection(My.Settings.CS)
            Dim cmd As New SqlCommand(sSQL, cn)

            cn.Open()
            cmd.ExecuteNonQuery()
            cn.Close()
