I want to write a program and submit it to the Internet as a Shareware.
And I got a few problems !!
1. What methods should I use so that a shareware-user can
not use my shareware when the timing limit expire..???
What function(s) should I use to calculate the timing limit even the user change the system-timing and it will not affect the timing-calculation of my shareware.
2. I am building up a shareware, so I want to know what is the most simple and security method to collect the money from the user who want to register to my shareware.
Pls answer the both two questions,
And Pls give the examples and descriptions !!!
Thanx very much !!!
