I'm trying to create a 'trial version' for a software of mine, currently it is pay-only. Basically the most efficient way I can think of is to simply change the startup form of the trial version after 15 days. The new startup form will simply be a request to register.
-How can I change the startup form after 15 days?
-How can I ensure that this cannot be changed afterwards (so it isn't easily pirated).
I'm looking for a way to change the startup form after 15 days. The best way to approach it seems to be by adding a registry key with the date on the first startup.

View 6 RepliesI can hide my startup form (or make it appear hidden) on startup. I can start my app on windows startup--through registry values--if the user checks a checkbox.
But if the app starts up on windows startup, I want the form to be hidden, so the program can just keep working without bothering anyone. If it starts up because the user started it, I want the form to be showing, because the user probably wants to change some settings or something.

That's it. I found a thread that speculated it might be do-able using System.Management but after looking through the documention in the library I can't find which might do that.
Note: It looks like this might be possible using BCDEdit (which I could call through a Shell command) but I can't find the syntax for that either. I only mention it because that would be a solution to my problem if it can't be done internally from the program I'm writing.
