Licensing for C++ Applications

QLM protects your C++ application with the same level of functionality and license protection that are supported with C# applications. With QLM C++ License Protection, you can provide permanent, trial or subscription based licensing to your customers. Your customers can easily activate their license online when connected to the internet or offline if they are not connected to the internet.

Our extensive license protection API is fully supported in C++.

In order to prompt the user for a license key and activate it, you simply launch the QLM License Wizard from your C++ application. The QLM License Wizard eliminates the need to develop any complex code in your C++ application to capture a license key and activate it. The QLM License Wizard is a standalone application that you launch from your C++ application. For more details about invoking the QLM License Wizard, refer to this article.

To help you get started, we provide sample C++ applications that you can use as a reference to implement licensing in your own C++ application. The samples are located in the following folders: 

  • C:\Users\Public\Documents\Quick License Manager\Samples\qlmpro\Windows\C++\QlmLicenseWizard\vc10
  • C:\Users\Public\Documents\Quick License Manager\Samples\qlmpro\Windows\C++\QlmLicenseWizard\vc10_NoMFC

The files that you need distribute with your C++ application are listed in this article.

You should also read our Step by Step guide to protecting a C++ application with licensing.
