Membuat CC Generator

Kita akan membuat sebuah CC generator dengan Visual basic. Okay, tapi gak jamin Valid loch hehehe.. namanya juga usaha.. ;)

1. Pada visual basic buatlah project baru dengan properti seperti dibawah ini :

Jenis Item Nama
- Form Form1
- ComboBox CmbCCType
- CommandButton CmdStart
- CommandButton CmdExxit
- TextBox Text1

2. Buka jendela code editor atau klick 2 kali pada form lalu ketik listing dibawah :

Option Explicit
Option Base 1
Dim num1, num2
Dim CCType As String
Dim AC_Prefix As String
Dim AC_Len As Byte, AC_Prefix_Digit As Byte
Dim AC_Value() As Integer
Private Function AddDigits(ByVal mValue As String) As Long
Dim iPosition As Long
Dim mSum As Long

mSum = 0
For iPosition = 1 To Len(mValue)
mSum = mSum + CLng(Mid(mValue, iPosition, 1))
Next iPosition
AddDigits = mSum
End Function

Private Sub CmbCCType_Click()
CmdStart.Enabled = True
End Sub

Private Sub CmdExit_Click()
Unload Me
End
End Sub
Private Sub CmdStart_Click()
On Error GoTo err1
Dim str1 As String, str2 As String

str1 = ""
str2 = ""

Next
