Cara Membuka VBA Microsoft Excel Dengan Macro

Sudah tidak perlu panjang-panjang penjelasannya. Berikut ini cara menggunakan Macro untuk Membuka VBA yang ter-password.

  • Buka File Excel yang terproteksi
  • Buat File Excel Baru
  • Tekan [alt] + F11 untuk membuka Microsoft Visual Basic for Applications
  • di VBAProject (Book1), Klik kanan Insert > Module
  • Akan muncul Module1, Copy-kan script ini
Option Explicit

Private Const PAGE_EXECUTE_READWRITE = &H40

Private Declare PtrSafe Sub MoveMemory Lib "kernel32" Alias "RtlMoveMemory" _
(Destination As LongPtr, Source As LongPtr, ByVal Length As LongPtr)

Private Declare PtrSafe Function VirtualProtect Lib "kernel32" (lpAddress As LongPtr, _
ByVal dwSize As LongPtr, ByVal flNewProtect As LongPtr, lpflOldProtect As LongPtr) As LongPtr

Private Declare PtrSafe Function GetModuleHandleA Lib "kernel32" (ByVal lpModuleName As String) As LongPtr

Private Declare PtrSafe Function GetProcAddress Lib "kernel32" (ByVal hModule As LongPtr, _
ByVal lpProcName As String) As LongPtr

Private Declare PtrSafe Function DialogBoxParam Lib "user32" Alias "DialogBoxParamA" (ByVal hInstance As LongPtr, _
ByVal pTemplateName As LongPtr, ByVal hWndParent As LongPtr, _
ByVal lpDialogFunc As LongPtr, ByVal dwInitParam As LongPtr) As Integer

Dim HookBytes(0 To 11) As Byte
Dim OriginBytes(0 To 11) As Byte
Dim pFunc As LongPtr
Dim Flag As Boolean

Private Function GetPtr(ByVal Value As LongPtr) As LongPtr
    GetPtr = Value
End Function

Public Sub RecoverBytes()
    If Flag Then MoveMemory ByVal pFunc, ByVal VarPtr(OriginBytes(0)), 12
End Sub

Public Function Hook() As Boolean
    Dim TmpBytes(0 To 11) As Byte
    Dim p As LongPtr, osi As Byte
    Dim OriginProtect As LongPtr

    Hook = False

    #If Win64 Then
        osi = 1
    #Else
        osi = 0
    #End If

    pFunc = GetProcAddress(GetModuleHandleA("user32.dll"), "DialogBoxParamA")

    If VirtualProtect(ByVal pFunc, 12, PAGE_EXECUTE_READWRITE, OriginProtect) <> 0 Then

        MoveMemory ByVal VarPtr(TmpBytes(0)), ByVal pFunc, osi + 1
        If TmpBytes(osi) <> &HB8 Then

            MoveMemory ByVal VarPtr(OriginBytes(0)), ByVal pFunc, 12

            p = GetPtr(AddressOf MyDialogBoxParam)

            If osi Then HookBytes(0) = &H48
            HookBytes(osi) = &HB8
            osi = osi + 1
            MoveMemory ByVal VarPtr(HookBytes(osi)), ByVal VarPtr(p), 4 * osi
            HookBytes(osi + 4 * osi) = &HFF
            HookBytes(osi + 4 * osi + 1) = &HE0

            MoveMemory ByVal pFunc, ByVal VarPtr(HookBytes(0)), 12
            Flag = True
            Hook = True
        End If
    End If
End Function

Private Function MyDialogBoxParam(ByVal hInstance As LongPtr, _
ByVal pTemplateName As LongPtr, ByVal hWndParent As LongPtr, _
ByVal lpDialogFunc As LongPtr, ByVal dwInitParam As LongPtr) As Integer

    If pTemplateName = 4070 Then
        MyDialogBoxParam = 1
    Else
        RecoverBytes
        MyDialogBoxParam = DialogBoxParam(hInstance, pTemplateName, _
                   hWndParent, lpDialogFunc, dwInitParam)
        Hook
    End If
End Function
  • Buat kembali Module2 dengan cara Klik kanan VBAProject (Book1), Insert > Module, dan paste kan kembali script di bawah
Sub unprotected()
    If Hook Then
        MsgBox "VBA Project is unprotected!", vbInformation, "*****"
    End If
End Sub

Jalan kan unprectected sampai muncul notifikasi VBA Project is unprotected!

Done, sekarang VBA seharusnya sudah terbuka dan tidak terkunci lagi…
