Bomb The Suburbs Pdf To Excel
Timebombing A WorkbookThis page describes how to limit the functionality of a workbook after a period of time.IntroductionThere may be circumstances in which you want to limit the functionality of a workbook after a specifiedperiod of time, such as distributing a demonstration or trial version of an application. Excel doesn't lend itself wellto doing this.
Nearly any limitation on a workbook can be circumvented by an experienced user. That said, there are anumbers thing you can do limit the usable life of a workbook, called time-bombing as workbook.Unfortunately, no VBA-based time-bombing method is foolproof. A skilled user can quite easily circumvent the time-bombcode and get full access to the workbook, even after it has expired.
The code on this page also requires that theuser has macros enabled. If macros are disabled, the code will not work.
(See for code to force the user to enable macros.) All that said, the time-bomb methods presented here are probably'good enough'. They will not prevent an experienced (and dishonest) user from circumventing the protection, but the code willwork for the vast majority of Excel users. All protection mechanisms in Excel are really intended to prevent the user fromaccidentally changing a value or some code. The security just isn't strong enough to provide real protection ofproprietary information or information or code with intellectual property value. For that level of security, you should bewriting your code in Visual Basic 6 or VB.NET.
See for details aboutcreating a COM Add-In and for details about creatingan Automation Add-Ins.A quick note regarding security in Excel: Security of any sort in Excel is extremely weak. There are many password breakersavailable on the internet.
I use PassWare's VBAKey and ExcelKey that can crack Excel and VBA Project passwords effortlessly,usually in a matter of seconds. In most cases, the password assigned to an object (a sheet, workbook, or VBA Project) isn't theonly password that will succeed in opening the object.
It is one of many mathematically related passwords, any one of which willwork. For example, in some tests of VBAKey, VBAKey will return not the password that I actually used to protect the project, buta seemingly random string of characters that will pass successfully through the password validation logic.As I tell all of my commercial clients, password protection, or protection of any sort, should be viewed as a method to keepthe honest user from accidentally changing or deleting something he shouldn't. The security is by no means sufficient toprotect proprietary data or code or code with intellectual property value.
The same goes for any sort of registry based keystorage or settings. A skilled user can easily run RegEdit and see the values in the registry. The same hold true for macrobased security. Not only can the VBA password be easily broken, but nearly all macro based security relies on macros being enabledin the first place and that the Application's EnableEvents setting is True.It is a one-liner to circumvent either of those two restrictions.The bottom line is that if you have valuable code and you need more than 'honest person' security, then VBA is not sufficient. Youshould create a COM Add-In in VB6 or a Shared Add-In or an Excel Workbook in VB.NET and Visual Studio Tools For Office.All of the procedures desribed on this page use the constant:Private Const CNUMDAYSUNTILEXPIRATION = 30You should change the value of this constant to number of days after the first usage of the workbook that the workbookshould be disabled. The value provided in the is 30 days.
On the 31st day after the first time the workbook is opened,it will become unusable.You can download anTimeBomb With A Defined NameThis procedure, TimeBombWithDefinedName, uses a hidden defined name to store the expiration date. The firsttime the workbook is opened, that defined name will not exist and will be created by the code. (Be sure that you delete this name whenyou are done with your own development work on the workbook.) When the defined name is created, it usesthe CNUMDAYSUNTILEXPIRATION constant to calculate the expiration date. When workbook is openedafter the first time, the code reads the name ExpirationDate and tests that value against thecurrent date.Sub TimeBombWithDefinedName' TimeBombWithDefinedName' This procedure uses a defined name to store this workbook's' expiration date. If the expiration date has passed, a' MsgBox is displayed and this workbook is closed.' 'Dim ExpirationDate As StringOn Error Resume NextExpirationDate = Mid(ThisWorkbook.Names('ExpirationDate').Value, 2)If Err.Number 0 Then' Name doesn't exist. 'ExpirationDate = CStr(DateSerial(Year(Now), Month(Now), Day(Now) + CNUMDAYSUNTILEXPIRATION))ThisWorkbook.Names.Add Name:='ExpirationDate', RefersTo:=Format(ExpirationDate, 'short date'), Visible:=FalseEnd If' If the today is past the expiration date, close the' workbook.
If the defined name didn't exist, we need' to Save the workbook to save the newly created name.' 'If CDate(Now) CDate(ExpirationDate) ThenMsgBox 'This workbook trial period has expired.' , vbOKOnlyThisWorkbook.Close savechanges:=FalseEnd IfEnd SubTimeBomb With SuicideA more extreme version of timebombing code is to permanently delete the workbook once the expiration date has passed.
I generallywouldn't recommend this approach, but it is certainly possible.CAUTION: This code will permanently delete (not Recycle) the workbook that contains the code. Once deleted, there isno way to get the workbook back.
