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
