2) Simpan Form (nama file : Calculator.frm)
3) Catatan :
Project tersebut bisa di download (file Calculator.frm) serta file-file latihan sebelumnya. Untuk menambahkan file Form ke dalam sebuah Project, lakukan langkah-langkah berikut ini :
1) Klik menu Project > Add Form. Kemudian klik tab Existing.
2) Tentukan lokasi file pada bagian Look in, lalu pilih filenya.
3) Klik tombol Open.
4. Klik menu Project > Project1 Properties lalu klik tab General. Gantilah Startup Object-nya menjadi Form.
5. Jalankan Project1. Perhatikan hasil setiap operasi !
4. Hasil Praktikum.
Software Visual Basic 6.0 yang telah didesain pada From, Properties dan Coddingnya sesuai dengan perintah penugasan ini, dapat berjalan.
Gambar Hasil Praktikum
5. Analisa.
Pada tugas ini, Software Visual Basic 6.0 dapat berjalan apabila pengisian data pada From, Propertis dan Coddingnya sama. Apabila antara Propertis dan Coddingnya berbeda maka tugas ini pada Software Visual Basic 6.0 tidak dapat terbaca/error pada program tersebut.
6. Kesimpulan.
Selama tugas ini, Software Visual Basic 6.0 dapat berjalan atau terbaca dengan baik sesuai dengan pengisian data pada From, Propertis dan Codding sehingga tidak ada kendala maupun kesalahan/eror pada data tersebut.
