Any way to know when my worksheets get opened at remote location?
Hi Guys,
I've been writing a fair few worksheets for a friend of mine that interact with his trading software and allow him to auto trade. I always believed they were just for him but I'm beginning to believe he may be selling them on. I don't know, I really hope not. I thought he was just coming up with wild systems to trade with and wanted to test until a winner is found. I'm no pro coder but a pretty decent amateur and would like to know if there's a quick and easy way to know if my sheets are being used in multiple locations. I'm aware that any sort of 'phone home' code could be seen as a potential threat, and that's the last thing I want to do. I've thought about a kind of logic bomb that stops the sheet working after a set number of weeks. Then requests a password to reset things which of course he gets from me. However, one single password isn't enough as he could easily distribute said same password and I'm still none the wiser. Any suggestions guys? Ron |

Ron Not quite sure how they do it, but many of the companies that I deal with that sell software require you to call in to get an unlocking code that looks at the hardware you are running the program on and keys it to the specific computer/PDA. You might want to look at something like that. |
