script ini berfungsi untuk menonaktifkan dan mengaktifkan task manager. ok, langsung aja kita coba praktek yaa.. :)
pertama buat project baru dan masukkan 2 komponen CommandButton, ubah Caption Command1 dengan "Enable Task Manager" dan Caption Command2 dengan "Disable Task Manager".
berikut ini adalah scriptnya:
Form1.frm
Private Sub Command1_Click()
AntiTaskManagerController True
MsgBox "Task Manager Enabled"
End Sub
Private Sub Command2_Click()
AntiTaskManagerController False
MsgBox "Task Manager Disabled"
End Sub
