Setelah bepanjang lebar membicarakan Addins, maka sekarang kita akan menerapkannya dalam sebuah project yang bermanfaat (jika dilanjutkan memprogramnya) yaitu: generator database yang sangat sederhana (hanya untuk MS Access saja, untuk database lainnya, silakan modifikasi kodenya). Project ini hanya akan mengenerate GUI-nya saja (tanpa kode), adapun jika jika ingin menambahkan kode-kode yang sesuai Anda dapat merujuk pada tautan di samping,
menambah kode pada module (tentu saja setelah dimodifikasi dan disesuaikan).
Langkah-Langkah:- Buat project Addin
- Masukan kode-kode di bawah ini:
Kode pada
