This guide shows how to create a limited Trial edition of Windows, Mac or Linux software using the QuickLicense API. Alternatively, use AddLicense wrapping tool included with QuickLicense. Wrap a compiled application with your license without programming. First, consider how you want the evaluation process to work. Your Trial edition can auto-activate on first launch for a specific computer or require user information before activation. User data can be entered through a dialog or web page before receiving an Activation Code by email, web page or instant activation. Trial software can expire after a specified number of minutes, hours, days or launches.
Once the trial period expires, the user must purchase a license. The vendor can extend the evaluation period with a secure Expiration Code. QuickLicense makes it easy to combine trial and product licenses into a single application presented to the user with a Try/Buy dialog. Step 1 - Configure Trial License
Step 2 - Test Your License
The Command and Response strings contain semicolon separated data fields that tell your application to run normally or quit.
The SendMessage application included with QuickLicense can be used to experiment with a configured Ticket file.
SendMessage sends a command to the QuickLicense runtime and displays the response. Use it to simulate your application's interaction with the runtime. Step 3 - Implement Protected Application
On Windows, QuickLicense runtime software is stored in a DLL file. Include the DLL and Ticket file with your application and call an external function to send a command. On Mac, the QuickLicense runtime is an application that can run with no menu commands or dock icon. The user sees an Activation dialog integrated within your application. The QuickLicense runtime is also available as a static library that compiles into an Xcode application or plugins for Xojo and FileMaker applications. QuickLicense comes with source code examples that show how to call the runtime from popular programming languages like C, C++, C#, Visual Basic, VB.Net, Objective-C, Delphi, RealBasic, Xojo, Java, FileMaker and other development environments.
Step 4 - Deploy Trial Edition
If your configured Ticket file presents an Activation dialog, that dialog can contain the URL of an activation page on your web site. An HTML form can collect the customer information and email it to you. Generate an Activation Code that is automatically emailed to the user.
An Activation Code can be immediately generated from the Safe Activation service. WebActivation or Desktop License Server running on your own Windows or Linux web server makes it easy to automate the activation process with a custom activation dialog.
