VBA 宏文件源代码密码解除

VBA Project密码解除
第一种方法详细步骤参考:
以下VBA代码是第二种方法

'使用本代码之前需要将需要解除密码保护的含有宏的Excel文件(如果是xlsm文件,需要先另存为97-03版的xls文件)关闭
'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
'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
