Hi,
I have 2 files (EXE) in my application:
MAIN.EXE: This file is the same for all customers and never is updated.
CUSTOM.EXE: Each customer have a CUSTOM.EXE that is different the others customers.
So, my problem is: How could I know if the CUSTOM.EXE is the valid? I mean, I want to check if other developer replace MY CUSTOM.EXE for other VFP EXE and have access to my database...
The EXEs should talk, then I'd have something like that:
MAIN.EXE talks: "Hey CUSTOM.EXE... Are you really?"
CUSTOM.EXE talks: "Yes MAIN.EXE! I'm the correct file."
This way, if other person change the MAIN.EXE:
MAIN.EXE talks: "Hey CUSTOM.EXE... Are you really?"
CUSTOM.EXE talks: "What??? ... ... ??? Yes, I'm!"
and then I know that CUSTOM.EXE is not MY CUSTOM.EXE ....
:-) Some ideas? :-)
TIA
