http://www.mcgimpsey.com/excel/removepwords.html -- Paul B Always backup your data before trying something new Please post any response to the newsgroups so others can benefit from it Feedback on answers is always appreciated! Using Excel 2002 & 2003 "Philip" wrote in message ... Hi, I don't understand why this code works...surely if I put a password on a worksheet to protect it, then only that password should unprotect it... what is wrong with this, is it a bug in Excel? here is the code: Sub PasswordBreaker() 'Author unknown 'Breaks worksheet password protection. 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 Dim lCount As Long 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) Debug.Print Chr(i) & Chr(j) & _ Chr(k) & Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & _ Chr(i3) & Chr(i4) & Chr(i5) & Chr(i6) & Chr(n) Debug.Print lCount Exit Sub End If lCount = lCount + 1 Next: Next: Next: Next: Next: Next Next: Next: Next: Next: Next: Next End Sub thanks if anyone can explain this behaviour of Excel where it seems to not in actual fact be secure at all...
