.net - Making Trial Version Of Program?
Jun 26, 2011I have searched lots of way to make a 30 day trial limit of my program. They say "Use -Settings- in visual basic application for your variables" to save the information about user (like : registered or not registered or when the program expire). (You can see the 'Settings' when you double-click on "my project" in "solution explorer") Does the data which we use with "settings" saved in our program or somewhere in the computer?

Mar 31, 2009How they relate and differ from each? What are the best practices for version control? Is there a primer about publish online? Or a good book?

BTW I am using VB if that makes any difference.

VS 2008 Check Difference Between A Full Version And Unregistered Version?
Sep 1, 2010I have created a license system for my application with MySql about half a year ago. What it would do is take the serial number and send it to my server if the key was correct it would return a 0 if its wrong the return value would be a 1.The problem was that when the serial number was entered correctly my program would create a "fake file" for example vb.dll in the system.And on run time my program would check for that vb.dll if the file exist it would skip my trial program and run the app as a full version. Half year later i think creating a "fake file" and checking for it on start up is extremely wrong and that's not very good security.How can i check the difference between a full version and unregistered version?

View 1 RepliesSmart Trial System Protection
Jun 1, 2010Just today I've completed a trial version of my application - I then uploaded it to my webserver, and to my surprise a user already (almost one hour after I uploaded it) bypassed the protection and used the software 8 times (instead of the limit of 1 use)!
My "protection" was pretty weak. After the program has been used, it just writes a value to a single registry key. The user just deletes this registry key and can use the program once more, and so if someone does this enough times, he can use the software for as much time as needed.
Anyway, since I'm not really experienced in programming, do you guys have some nice working and possible easy to implement trial protection? I'm not looking for anything too serious, but it shouldn't be as easy to bypass as my current protection.
