The way to protect certain portions of your code with BLT for LabVIEW is to create Product Features.
A Product Feature means for something that you can enable or disable for a particular license or group of licenses.
In this tutorial, we are going to create 2 Product Features: Base and Professional.
Depending on which of those features is enable for a specific license, the user will not be able to access certain portions of your program.
You are now ready. Your product contains 2 versions Base and Professionnal and some features of your code will be unaccessible for users who don't have rights to this Product feature.
