[Tutorial] Membuat Task Manager Sendiri (VB6)

Code:

Skrip untuk membuat tampilan seperti task manager dengan
Visual Basic 06. Setiap process pada yang sedang berjalan
pada windows dapat dilihat dalam bentuk PID (ProcessID) dan
path. Setiap process yang ada bisa dimatikan asalkan
tidak dilindungi oleh system. Skrip ini juga
menggunakan listview yang memerlukan file component mscomctl.ocx.

Langkah awalnya adalah, Siapkan bahan2nya terlebih dahulu.

1. VB6 Portable/Initable (cari saja di google)
2. MSCOMCTL.OCX

Step by step.

• Buka VB6 Kamu, Buat project baru.
• 3 Buah Command Button, Masing2 beri nama cmdMatikan, cmdRefresh, cmdTutup inget Name bukan Caption.
• Pada 3 buah Command tersebut beri saja Caption "&Matikan", "&Refresh", "&Tutup".
• 1 Buah ListView1
• Isikan Code berikut pada Form 1 kamu

Code:
