UAS Pemrograman Visual Basic
Program ini dibuat untuk memudahkan suatu universitas dalam pendataan mahasiswa, program ini sudah dapat memanipulasi data seperti create, read, update, delete.
Berikut adalah beberapa screenshoot pada saat program dijalankan.
- Pada saat cari
- Pada saat update
- Pada saat menghapus
Berikut adalah source code nya :
