Hi people!!!
I was trying to protect an workbook that uses vba code against changes by other users but since excel protection is too poor I need your help...
What I intend to do is allow the users of the workbook to use it until one fixed day (for instance, 30th June 2008). After this date the workbook should be inoperational.
In this case, I think that the best way is to use some code that checks the actual date and compares with the fixed date, allowing or not to use the workbook. Since anyone can alter computers' date, it is possible to check the date in the internet and only on that conditions allow to use the wb?
I also tried to use an external application, Lockxls, that seemed to do that, but with that application the macros were almost of impossible use do to an enormous increase on running time...
I will apreciate a lot if you can help me with this issue.
Thanks in advance
