Untuk Membuat Screenshot / screen capture menggunakan visual basic 6 cukup membutuhkan kejelian dan sedikit skill image properties dan picturebox properties, tapi saya akan mencoba mempermudah dalam Membuat Screenshot / screen capture menggunakan visual basic 6 ini dengan cara buatlah satu form dengan komponen-komponen sebagai berikut:
- 6 button
- 1 picturebox
Lalu buatlah sau module dan masukkan kode dibawah ini:
Setelah dibuat module dengan kode diatas kemudian klik 2 kali form yang sudah didesign seperti gambar diatas, hapus semua kode dan masukkan kode dibawah ini:Option Explicit
