Excel VBA工程密码破解程序 (绝对可以破解)2007-06-24 11:28新建一个Excel工作簿,Alt+F11 打开VBA编辑器,新建一个模块 ,复制以下代码,注意如提示变量未定义,则把Option Explicit行删除即可,经测试已经通过.

'移除VBA编码保护
Sub MoveProtect()
Dim FileName As String
FileName = Application.GetOpenFilename("Excel文件（*.xls & *.xla）,*.xls;*.xla", , "VBA破解")
If FileName = CStr(False) Then
Exit Sub
Else
VBAPassword FileName, False
End If
End Sub

'设置VBA编码保护
Sub SetProtect()
Dim FileName As String
FileName = Application.GetOpenFilename("Excel文件（*.xls & *.xla）,*.xls;*.xla", , "VBA破解")
If FileName = CStr(False) Then
Exit Sub
Else
VBAPassword FileName, True
End If
End Sub

Private Function VBAPassword(FileName As String, Optional Protect As Boolean = False)
If Dir(FileName) = "" Then
Exit Function
Else
FileCopy FileName, FileName & ".bak"
End If

Dim GetData As String * 5
Open FileName For Binary As #1
Dim CMGs As Long
Dim DPBo As Long
For i = 1 To LOF(1)
Get #1, i, GetData
If GetData = "CMG=""" Then CMGs = i
If GetData = "[Host" Then DPBo = i - 2: Exit For
Next

If CMGs = 0 Then
MsgBox "请先对VBA编码设置一个保护密码...", 32, "提示"
Exit Function
End If

If Protect = False Then
Dim St As String * 2
Dim s20 As String * 1

'取得一个0D0A十六进制字串
Get #1, CMGs - 2, St

'取得一个20十六制字串
Get #1, DPBo + 16, s20

'替换加密部份机码
For i = CMGs To DPBo Step 2
Put #1, i, St
Next

'加入不配对符号
If (DPBo - CMGs) Mod 2 <> 0 Then
Put #1, DPBo + 1, s20
End If
MsgBox "文件解密成功......", 32, "提示"
Else
Dim MMs As String * 5
MMs = "DPB="""
Put #1, CMGs, MMs
MsgBox "对文件特殊加密成功......", 32, "提示"
End If
Close #1
End Function
