Contoh Metode Kloning (VBScript)
Contoh ini menggunakan metode Kloning untuk membuat salinan Recordset lalu memungkinkan pengguna memposisikan penunjuk rekaman dari setiap salinan secara independen.
Gunakan contoh berikut di Halaman Server Aktif (ASP). Contoh ini menggunakan database Northwind yang didistribusikan dengan Microsoft Access. Potong dan tempel kode berikut ke Notepad atau editor teks lain dan simpan sebagai CloneVBS.asp. Anda dapat melihat hasilnya di browser klien apa pun.
Untuk menjalankan contoh, ubah baris RsCustomerList.Source = "Customers" menjadi RsCustomerList.Source = "Products" untuk menghitung tabel yang lebih besar.
