Path Windows Proccess

Kadang pada saat membuat aplikasi yang berhubungan dengan keamanan suatu system windows maka diperlukan suatu progran yang dapat mendeteksi alamat/path suatu file yang sedang berjalan/melakukakan proses di windows... apakah file target tersebut akan ditutup prosesnya ataukah akan dihapus.
Kali ini kita hanya akan membuat suatu program yang berfungsi untuk mengetahui alamat/path suatu file yang sedang berjalan berdasarkan Process ID (PID) file tersebut, jika lebih kreaatif tentu nanti dapat ditambahkan fungsi-fungsi "Protector" lainnya misalkan menutup/close file, mendapatkan sign/tanda crc32 file tersebut atau juga dapat menghapus file tersebut dari konputer kita. Langsung saja ini source codenya...

Masukkan source code ini pada form..
