3D Shape VB 2008

Tips kali ini kita akan membuat visual Grafik 3D dengan menggunakan Visual Basic 2008. Tampilannya perhatikan Gambar di bawah ini:

Ikuti langkah-langkah di bawah ini, rancang interface/antarmuka pada Form menggunakan ToolBox seperti gambar di bawah ini:

Source listing program dari perancangan/design di atas, ketikkan dengan mengklik kanan pada design dan pilih View Code.
