RE: [boost] Re: prob using lexical_castOk,

Stupid Error : "1000" is a char*, not a string !!!
with lexical_cast<short>( string("1000") ) (my modified version), I can throw an exception if the signed type is not take correctly in account.

Next step : have the signed type taking in account (I'll work on it at home...)

Bye.
(sorry)

  Because you're not comparing strings, like in the example above. You're comparing (different) pointers, not values.
