What do the Items on the properties tab of MSVC++ mean?

Question

I was playing around with my MSVC++ compiler, and the properties tab for my point class said:

IsAbstract  - false
IsInjected  - false
IsManaged   - false
IsSealed    - false
IsTemplate  - false
IsValue     - false

What do these mean, and why were all of them greyed out except IsAbstract and IsSealed?

Answer 1

A sealed class is one that you cannot inherit. I assume IsSealed - false means that you can inherit from it.
