I could have wrapped my code in DLL, but I wanted a simple solution without any change to the existing addin file format (xlam) I was hoping that someday there will be a software that can protect VBA projects and make them unbreakable, and here is the Secure++ application! My dream has finally come true :-) I like sharing my knowledge, but not my personal custom VBA solutions. I was frustrated when I learned that intruders were hacking my VBA projects. The non-profit organization where I work, employs approx 7000 employees around the globe. One challenge I had, was that my custom user defined functions (UDFs) were poorly protected. I develop custom solutions in Excel and other popular applications to increase the productivity of myself and that of my colleagues at work. Though, by profession I am not a developer, I have been using Excel and VBA solutions for more than a decade. I work for a non-profit organization in their headquarters and my daily duties involve computation and calculation of complex financial analysis. Simply put, I love the Secure++ VBA application! I have used it several times to protect VBA code in my addin files (.xlam).
