incorrect operator: logical-not (!) is not interchangeable with ones-complement (~)

Yes

Yes

C6318

Ill-defined __try/__except: use of the constant EXCEPTION_CONTINUE_SEARCH or another constant that evaluates to zero in the exception-filter expression. The code in the exception handler block is not executed

Yes
