Answer 1

Hi, could you explain better your question?
You wanna make a shareware/trial program that expires in few days and you need to buy a license?

If yes, then have many ways to do it, just use your imagination.

One example:
-Make your program create a file with the time that the software was installed, then everytime the software is open check the actual date and compare how many days from install date the program has.
-You can also encrypt the data and make the program crash if anyone change the files contents.
-You can save the id of hard drive of the computer to avoid people to use the license of one computer in another.
-You can create a license generator based on these information.
-... use your imagination....
