Excel and VBA, how to protect?
The company my Dad works for have had some stuff done in Excel which includes macros and VB code that has been written by them. The macros are password protected so people can't steal them (supposedly) but now they want to give the program out to a few customers. They've asked me if it's possible to give a good level of protection to their program and also if the program can have a usage timeout (stops working after 30 days) that can be set by them before they give it to the customer. I don't know why they've done it in Excel as the security in there is always crackable and they don't have time to let me rewrite the whole thing in VB or something. They will be giving the program to customers on CD. Anyone have any ideas? I've looked at the standard workbook passwords and VB password stuff and also creating a dll but it doean't seem very good. As for the CD protection timeout that probably can be done but with 3rd party software.
