Making a trial version of my program ?

Hey there,

was wondering if there is a simple / quick way of making a trial version of my software which will expire after say 30 days of use?

thanks in advance !

The best way is to purchase one of the many third party pieces of software out there. However a crude way would be on first use of the app, to write a date flag to the Registry, then on each subsequent load check the date placed in the registry with the current date and simply shut down if it goes past the 30 days.

I have also heard of people using a switch in the command line of the executable - maybe to run it in "debug" mode or "trial" mode (set a DOS switch like /d or /t in the command line associated with the executable). Another crude way of doing it... it could work, but it would be easily hacked.
