Execute Stored Procedure from VB

[FastEddie]

This is what if ended up with and it seems to work fine. However I am wondering if there is something that I can add that will tell me the procedure finished the task?

        Dim cn As SqlConnection = New SqlConnection
        cn.ConnectionString = Con
        cn.Open()
        Dim cmd As SqlCommand = New SqlCommand("sp_InsertInv", cn)
        cmd.CommandType = CommandType.StoredProcedure
        Try
            cmd.ExecuteNonQuery()
        Catch ex As Exception
            MessageBox.Show(ex.Message & vbNewLine & _
            ex.Source, "Data Error", MessageBoxButtons.OK)
        End Try
