dll - C++: 'adding references' to namespaces (and class libraries)? -

-

i'm curious adding references through "property pages" dialog in visual studio c++. adding 'class libraries' and, more so, 'namespaces'.

in i'm reading says both 'class library's , 'namespaces' can referenced in way-- can see reference 'class libraries' (bringing in dll able access it's '.h' files , such-- correct me if i'm wrong). referencing namespace do? understand 'using' declarative allows not qualify namespace anymore-- 'referencing namespaces' way that?

to clarify mean 'referencing': i'm talking when right clicking on project in solution explorer , selecting 'references' brings 'property pages' dialog , selecting 'add new reference...' button.

'add reference' in .net #includeing in normal c++. allows use classes , namespaces inside .cs file, not in project, e.g., system libraries.
if you're coding normal c++, don't worry it.
