Hello Peter,
I am still trying to understand how to implement a RibbonBar menu. I was able to start an example into the QuizMasterManager project, but I read from this post that it's better to use vdfsig. To use the cSigCJRibbonBar do I need to buy the Codejock SuitePro or is it enough the version delivered with the runtime?
If the runtime version is enough, can you give me some advices how to create an empty project with the cSigCJRibbonBar? I have tried but I receive an ActiveX error not properly installed or registered 0x80040154. I did my experiments with DF 19.0.

Thank you very much
Luca
