Macro to expire after a specified date
Sir,
I want to use your "Time Bomb" VB code, but I have question on the "Defined Name". What name is it that we are to remove from the VB code? Thanks "Chip Pearson" wrote: You could adapt the code on my "Timebombing A Workbook" page at www.cpearson.com/Excel/WorkbookTimeBomb.aspx . Note that no VBA-based protection scheme is foolproof. An experienced (and dishonest) user can work around any protection you provide. However, code such as is on the page referenced above is "good enough" for the vast majority of users. -- Cordially, Chip Pearson Microsoft MVP - Excel Pearson Software Consulting www.cpearson.com (email on the web site) "Dileep Chandran" wrote in message oups.com... Hello Masters, How can I program a macro so that it expires after Jan 01, 2008. Any help is greatly appreciated. Thanks -DC |

Macro to expire after a specified date
Specifically what piece of code are you referring to? The web page provides
several different methods of time bombing a workbook. The first one described on the page uses a defined name called "ExpirationDate" that contains the data after which the workbook is unusable. If you want to remove the time bombing, you should delete that name. Of course, then next time you open the workbook the name will be recreated. To permanently remove the time bomb, you need to delete the VBA code. -- Cordially, Chip Pearson Microsoft MVP - Excel, 10 Years Pearson Software Consulting www.cpearson.com (email on the web site) "pgarcia" wrote in message ...

Thanks, also, do you put this in the "This Workbook" or it's module?
Option Explicit Private Const C_NUM_DAYS_UNTIL_EXPIRATION = 90 Sub TimeBombWithDefinedName() Dim ExpirationDate As String Dim NameExists As Boolean On Error Resume Next ExpirationDate = Mid(ThisWorkbook.Names("ExpirationDate").Value, 2) If Err.Number < 0 Then NameExists = False ExpirationDate = CStr(DateSerial(Year(Now), _ Month(Now), Day(Now) + C_NUM_DAYS_UNTIL_EXPIRATION)) ThisWorkbook.Names.Add Name:="ExpirationDate", _ RefersTo:=Format(ExpirationDate, "short date"), _ Visible:=False Else NameExists = True End If If CDate(Now) CDate(ExpirationDate) Then MsgBox "This workbook trial period has expired.", vbOKOnly ThisWorkbook.Close savechanges:=False End If End Sub "Chip Pearson" wrote: Specifically what piece of code are you referring to?

Chip,
Is the same approach used when a "commercial" add-in requieres registration after a trial period, do you know how it would work? Do you have any literature on it?

Macro to expire after a specified date
Hi Chip,
Your code is great, but I seem to have encountered a problem. The code creates the "ExpirationDate" fine on one machines with the value being the date e.g. 39555, whilst on a different machine it is being captured as a text e.g. "18-03-08". I have changed the the visibility to true so that i could see the value. ThisWorkbook.Names.Add Name:="ExpirationDate", _ RefersTo:=Format(ExpirationDate, "short date"), _ Visible:=True I have checked all the settings in excel but could find no differences on either machines. Do you have any idea?
