* example needed to mitigate dev floundering (MicrosoftDocs#4210)

It is not easy to match up variant vt types with POD types. Especially since there is a gradual transition to modern C++. I used a number of dev hours on attempts to match the variant type, vt, to make the true/false work. The m_bValue type for the simple property was a BOOL  type, but trying to create a variant of type BOOL directly didn't work. Only by looking at VC Sample code for VisualStudioDemo did I see the (_variant_t)true construct, which becomes the standard_cast contruct in modern C++. I figured my Example code could make other programmer's efforts easier.
