How can I protect my program by means of Regitration process

Question

See more:

I am almost done writing an application and of course part of the development cycle is to have the application tested by potential users to make sure the application is bug free and that the application logic and flow conforms to the expectations of the industry.

While the application is a "Beta" release it is fully functional which means it can be distributed without my knowledge unless of course I have a Registration process in place where the user is required to register the application first before they can use the software.

On this note and since I am doing a Beta release, is there any way that I can set a specific time period, something like 30 days or 60 days, before the application forces the user to register.... very similar to the demo version of Microsoft applications ?

Regards,

Tino

The product that Vedat Ozan Oner suggests seems interesting although I have not tried it myself.

I have worked on a demo of a product activation. It can get real complicated to start from scratch.

I you do an article search here on Code Project for "License" then it will pop up several articles that go thru various ways to do it on your own and give you some ideas of what could be involved.

This simple way would be to just add something that records the install date and time and every time the program starts do the math on current date time and the install date. But it would be easy to bypass by just changing the date without encoding or encrypting the information.

You also have to remember that unless you obfuscate the code using one of several programs it can be easily reversed engineered.

Solution 1

you need a license server. and you have two options at this point.
1- either you buy a commercial product
2- or you write one.

I have used this: Install Key[^]. I hope this product gives the idea.

Vedat, thank you very much for you reply and the information contained therein. It is certainly good to know about solutions which has been tried before. Install Key is not all that expensive if you consider the time and effort already invested in creating a commercial application and to spend $89 is a small investment to protect you from potential major losses.

Thank you again.
