excle VBA 破解

這種方法實際是避開VBA工程密碼驗證，即，騙vba編輯器，該密碼輸入成功，請求放行。
原理很少說了，先將方法公佈：

1.新建一個工做簿，打開，按ALT+F11，進入vba代碼編輯器窗口：
2.新建一個模塊，「插入」--「模塊」把如下代碼複製進模塊並保存

Option Explicit
Private Declare Sub MoveMemory Lib "kernel32" Alias "RtlMoveMemory"  (Destination As Long, Source As Long, ByVal Length As Long)
Private Declare Function VirtualProtect Lib "kernel32" (lpAddress As Long,  ByVal dwSize As Long, ByVal flNewProtect As Long, lpflOldProtect As Long) As Long

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

Private Declare Function GetProcAddress Lib "kernel32" (ByVal hModule As Long,  ByVal lpProcName As String) As Long

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

Dim HookBytes(0 To 5) As Byte
Dim OriginBytes(0 To 5) As Byte
Dim pFunc As Long
Dim Flag As Boolean
Private Function GetPtr(ByVal Value As Long) As Long
    GetPtr = Value
End Function
Public Sub RecoverBytes()
    If Flag Then MoveMemory ByVal pFunc, ByVal VarPtr(OriginBytes(0)), 6
End Sub
Public Function Hook() As Boolean
    Dim TmpBytes(0 To 5) As Byte
    Dim p As Long
    Dim OriginProtect As Long

    Hook = False
    pFunc = GetProcAddress(GetModuleHandleA("user32.dll"), "DialogBoxParamA")
    If VirtualProtect(ByVal pFunc, 6, &H40, OriginProtect) <> 0 Then
        MoveMemory ByVal VarPtr(TmpBytes(0)), ByVal pFunc, 6
        If TmpBytes(0) <> &H68 Then
            MoveMemory ByVal VarPtr(OriginBytes(0)), ByVal pFunc, 6
            p = GetPtr(AddressOf MyDialogBoxParam)
            HookBytes(0) = &H68
            MoveMemory ByVal VarPtr(HookBytes(1)), ByVal VarPtr(p), 4
            HookBytes(5) = &HC3
            MoveMemory ByVal pFunc, ByVal VarPtr(HookBytes(0)), 6
            Flag = True
            Hook = True
        End If
    End If
End Function
Private Function MyDialogBoxParam(ByVal hInstance As Long, _
        ByVal pTemplateName As Long, ByVal hWndParent As Long, _
        ByVal lpDialogFunc As Long, ByVal dwInitParam As Long) As Integer
    If pTemplateName = 4070 Then
        MyDialogBoxParam = 1
    Else
        RecoverBytes
        MyDialogBoxParam = DialogBoxParam(hInstance, pTemplateName, hWndParent, lpDialogFunc, dwInitParam)
        Hook
    End If
End Function

3.右擊sheet1工做表，「查看代碼」複製如下代碼進去並保存：

sub 破解()
if hook then msgbox "破解成功"
end sub
sub 恢復()
RecoverBytes
msgbox "恢復成功"
end sub

複製代碼

4.到此,一個vba破解程序完成了,回到該工做簿窗口,文件-打開 打開須要破解vba工程密碼的工做簿.
5.運行"call 破解" 稍後你再雙擊剛纔要解密的VBA工程窗體.是否是如入無人之境啊,工程保護密碼形同虛設啊?！
6.破解完成後,請右鍵剛破解的VBA工程,在"查看工程時須要密碼"的地方複選框取消選擇,OK.完成.
7.完成後別忘了執行"call 恢復",恢復密碼保護(恢復程序的密碼保護,已被破解的文件不受影響.
