Shareware Lock Library - Would you like to offer a demo or trial version of your Windows or Windows Mobile application? Would you like to offer a shareware version of your application?
Our Library comes in 2 flavors (a .NET Framework 2.0 library - for Windows Computers and a .NET Compact Framework 2.0 library - for Mobile devices). They both allow you to easily and securly offer trial versions of your software. Using only 2 lines of code you can limit your users to a trial period lasting any number of days. The first step is to generate a Registration Key that is unique to your product using our custom website. The second step is to add Shareware Lock Library to your code.
The Shareware Lock Library is very simple to use:
First add a reference to SharewareLockLibrary.dll & then declare a SharewareLock object passing your program specific Registration String.
That's it!
The DemoDaysRemaining property returns the number of days remaining based on the number you entered when you generated your Registration String (referred to as YOURVALUE in the following):
Here is how to interpret the integer value of the DemoDaysRemaining property
obj.DemoDaysRemaining > YOURVALUE = the software has been registered
obj.DemoDaysRemaining < YOURVALUE and obj.DemoDaysRemaining >= 0 means the software is within the trial period
obj.DemoDaysRemaining < 0 means the trial period has expired
note: when obj.DemoDaysRemaining == 0 the software is running on its last trial day
How does it work?
If you are like me, I'm sure you are curious as to how this works.. ..and if you are like me, you also don't want me to tell you. Because, like all registration schemes it can be cracked given enough time and effort. And, knowing how it is done is the first step to piracy. Here are the key features of our product:
Use of the Windows or Device Registry (so you don't have to)
Use of PKI encryption (so you don't have to) - the strength of our method lies in the Registration String that is unique to each product
Hacker attempts to reduce or eliminate the trial period will end the trial period
Once the trial period has expired, the trial can not be restarted by reinstall, deleting registry keys, or manipulating the registry keys
You should verify the number of trial days remaining from time to time with by checking the DemoDaysRemaining property. This is especially important if your program is intended to run for several days at a time.
Be sure to read "Important Note" below.
For developers everything is very simple (2 Lines of code are all that is needed to get the number of days remaining of your product) SharewareLock locker = new SharewareLock( regStr, 'Twoopy Entertainment', 'TimerDeluxe' ); int daysRemaining = locker.DemoDaysRemaining;
Shareware Lock works with our Dynamic Registration Library found at Handango.com. With Shareware Lock and the Dynamic Registration Library you can offer hands-off customer registration as a Handango developer.
