Re: lexical_cast with unsigned short

19 Aug 2003


      After changing boost::lexical_cast<unsigned short>(aStr);  to
boost::lexical_cast<unsigned short>(aStr.c_str());
I had no problem compiling the program.

Cheers,
Stephan

If possible, please advise.
using lexical cast w/unsigned short fails, on MSVC7:
#include 
#include <iostream>
int _tmain(int argc, _TCHAR* argv[])
{
 std::string aStr("2");
 unsigned short i = boost::lexical_cast<unsigned short>(aStr); \\ ERROR!
std::cout << i << std::endl;
 return 0;
}
