Hello,
I'm developing a shareware sdk-like library (using C++). The library is a simple dll provides some functions. So, my first question is what types of trials are possible for simple dll? I don't want to cut the functionality of the trial dll, so I tend to use time-trial.
I roughly understand how to track usage time of the lib, so the second question is how to indicate expiration of the trial period?
There are two ideas for the present:
After evaluation period expires, the library will fail to load.
or
- After evaluation period expires, the library will load successfully, but will display some kind of a nag-screen.
But both them seem quite rough, so could you please give some advices on this?
Thanks!
