i tried to reinstall visual studio but it did not work...

why do i get these errors?
whats sourceannotations.h?
how can i solve this?

Could you paste you code here?

the point is that the errors aren't in my code

At least post the order of your headers at the top of your code. Is a header you wrote listed ahead of some of the standard ones? If so, you may be missing a ; after one of your class declarations.

whops i changed one thing in the file sourceannotations.h. work't after remove using in front of namespace

I wouldn't modify any of the headers like that, but okay.
