How to provide trial version of software ?

[Niclas]

Hi,

I have deveoped a piece of software (.Net 1.1) which I would like to
release a 30 day trial version of. Does anyone know how to do this, or
if there are any best practices ? Is there any built in support for time
restrictions in the framework ?

Hi Niclas,

..NET does not provide that functionality. Basically you can buy a component
that does that for you, or you can develop it storing data in a hidden
registry entry or file location and manage yourself to prevent
reinstallations or clock rollbacks.

If you are serious about selling software, I recommend you to join some
professional association like http://www.asp-shareware.org/ where they have
private newsgroups and resources with such kind of advice, far from the
public eye.

I recommend checking out the Shareware starter kit availble at http://msdn.microsoft.com/vbasic/downloads/starterkits/default.aspx.
You should be able to find some ideas on building a timeout trial mechanism
in there.

Normally you would purchase this code from a vendor. Google for (protect
software) and you will find many hits.
