Hello, Is there any way to have the customer disable an ebook once it's been purchased (if they request a refund)? I was thinking about the possibility of a special key combination or something that would reset the password or just plain make the book unaccessible. Here's one possible scenario... The customer requests a refund I explain to the customer that in order for me to process a refund he or she must press and hold "Ctrl" + "r" + "f" and read me the refund code. The customer presses those keys, it disables the eBook password and directs him to a page with a number on it (maybe his user ID or something). He or she must provide me with that number before I issue the refund.
The only obstacle is to make that disabled state persist the next time the user attempts to open the book, or worse yet, reinstall it.
The first solution is to save the value that determines the user access in an external file (it could be an .ini, .js. .as or perhaps an oddly named file), in an obscure place. You wouldn't want the user to be aware of it, because deleting it would allow the book to be reinstalled.
The second, better and more involved solution would be to build an online Access or SQL database of disallowed userIDs. That would be a lot smaller list (hopefully) than allowed IDs.
Your reader would 'activate' their book the first time they opened it.
Your ebook would check in online to see that it was legal to open on this user's pc. If the user was not online, it would check a few more times before shutting down, and requesting an online activation.
After disabling an ebook, any time it is opened thereafter, it would check back again to see if the ID was still on the disabled list, and behave accordingly.
That way, you could enable and disable the ebooks at will.
There is a third party add-on product that provides a remote disabling capability, that has been mentioned on this forum. If I remember the name correctly, it's called something like Hyperlock. Search for old discussions on it.
I don't know it does exactly what you want, but I think it does something similar.
Of course, feel free to roll your own solution if you prefer
The [color=blue]HYPrLock[/color] Refund Disabling system now works with or without an online database. You choose which version you want to use. Once a customer requests a refund, your ebook is automatically and permanently closed. NEW Super Easy version.
Descriptions and downloads are available at the HYPrLock web site.
Sunil, Thanks for the tip. I just installed the HYPrLock system. It works just peachy and does exactly what I wanted it to - namely, give me the ability to make sure people requesting refunds disable their eBooks before I give them their money back. I'd recommend it to anybody who wants security for their eBooks without having to pay a monthly fee. Keith
