今天下载了一个Excel2003文档，对里面的一些函数甚是感兴趣，但郁闷的是作者对文档进行了加密，有函数的地方全部设成只读属性了！在Excel的菜单中点击”撤销工作表”,提示输入密码!原来如此,上网搜了一个VBA宏破解的方法,一下就成功了啊!牛人还真的多啊!不得不佩服啊,下面就说一下这个方法吧
1． 点击“宏”→“录制宏”，出现“录制新宏”窗口，在“宏名”定义一个名称为：PasswordBreaker，点击“确定”退出;
2． 再点击“宏”→“查看宏”，选择“宏名”下的“PasswordBreaker”并点击“编辑”，打开“Microsoft Visual Basic”编辑器，用如下内容替换右侧窗口中的所有代码：
Sub PasswordBreaker()
Dim i As Integer, j As Integer, k As Integer
Dim l As Integer, m As Integer, n As Integer
Dim i1 As Integer, i2 As Integer, i3 As Integer
Dim i4 As Integer, i5 As Integer, i6 As Integer
On Error Resume Next
For i = 65 To 66: For j = 65 To 66: For k = 65 To 66
For l = 65 To 66: For m = 65 To 66: For i1 = 65 To 66
For i2 = 65 To 66: For i3 = 65 To 66: For i4 = 65 To 66
For i5 = 65 To 66: For i6 = 65 To 66: For n = 32 To 126
ActiveSheet.Unprotect Chr(i) & Chr(j) & Chr(k) & _
Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & Chr(i3) & _
Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)
If ActiveSheet.ProtectContents = False Then
MsgBox "One usable password is " & Chr(i) & Chr(j) & _
Chr(k) & Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & _
Chr(i3) & Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)
ActiveWorkbook.Sheets(1).Select
Range("a1").FormulaR1C1 = Chr(i) & Chr(j) & _
Chr(k) & Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & _
Chr(i3) & Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)
Exit Sub
End If
Next: Next: Next: Next: Next: Next
Next: Next: Next: Next: Next: Next
End Sub
3． 再点击“宏”→“查看宏”，选择“宏名”下的“PasswordBreaker”并点击“执行”，密码就现形了
我是在Excel2007中打开的,根本就不需要撤销密码保护,直接就可以了啊!而且也没有”撤销工作表保护”的菜单。
