Hi
I'm moving one of my programs from MSVC 6 to .NET 2003 and now the librare is changed so that
basic_istream::get calls setstate(failbit) if no elements was extracted

Is there any clean way to go around this, for me a empty string is a normal case?

Regards
Per

Hi Per,

This is as the C++ standard specifies in 27.6.1.3 paragraph 3 (in my TC 1
version of the standard):

Effects: .. After constructing a sentry object, extracts a character c, if
one is available. Otherwise the function calls setstate(failbit), which may
throw ios_base::faillure.

Can you use peek() as a workaround?
