membuat program memiliki waktu trial/expired

Kali ini penulis akan mencoba membuat program expired/shareware yang berfungsi untuk menonaktifkan program sesuai dengan masa waktu yang sudah kita tentukan, ini adalah sebuah contoh demo yang bisa kalian kembangkan sendiri sesuai ide dan kreasi kalian.
Pemakaiannya mudah, tinggal jalankan program shareware.vbp kemudian sharetest untuk mengetes apa program tersebut sudah dibuat shareware, nah jika sudah habis masa waktunya program meminta no register dan silakan masukkan no register a1234.
Berikut bentuk tampilan programnya



script kodenya sebagai berikut :

'main form shareware

Private Sub Command1_Click()
frmshare.Show

End Sub

Private Sub Command2_Click()
Dim lresult As Long
lresult = DeleteRegKey("\Software\venky", "value")
lresult = DeleteRegKey("\Software\venky", "days")
lresult = DeleteRegKey("\Software\venky", "uses")
lresult = DeleteRegKey("\Software\venky", "lock")
lresult = DeleteRegKey("\Software", "venky")
End Sub

Private Sub Command3_Click()
Unload Me
End Sub


Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As Integer)
Dim lresult As Long

' Remove the test data from the registry

End Sub
