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; }

New subject: [Boost-Users] lexical_cast with unsigned short

well, when I change _tmain to main and _TCHAR to char and the \\ to // it compiles and runs (debug compile) on vs.net2003 boost extracted from CVS yesterday btw, when you say \\ERROR what do you mean? what version of boost are you using? At Friday 2003-08-15 12:24, you wrote:

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 Charles Schwartz schrieb:
