  1. Klik Control’s Toolbox Icon.
  2. Gerakkan pointer mouse ke atas Form Anda. Perhatikan bahwa mouse pointer berubah menjadi crosshair (tanda silang), bukan panah. Klik dan tahan tombol mouse. Saat Anda menahan tombol mouse, Anda akan melihat outline dari control yang Anda gambar.
  3. Saat Anda melepaskan tombol mouse, control akan muncul.

Menggunakan kontrol intrinsik dalam Visual Basic, menambahkan kontrol ke formulir, menggambar kontrol pada formulir.
