[Boost-users] lexical_cast not throwing exception when converting negative value to UINT

Dear subscribers,

 

I am using lexical_cast to cast a string to an UINT, unfortunately, it
is not throwing an exception if a value is negative.

 

Example:

 

std::wstring failString = L"-1";

UINT nTest = boost::lexical_cast<UINT>(failString);

 

This does not throw a bad_lexical_cast exception, which it should, as -1
is not a valid unsigned integer.

 

Perhaps I am using the wrong function, or using this one incorrectly,
I've only just started using boost after moving to a new project that's
not based on ancient legacy code!

 

Regards,

Kris Wragg
