Hi: What is the best way (in terms of efficiency) to convert an std::vector of wchar_t to std::wstring. I can think of a oupple of aproaches: 1. using std::copy. 2. using boost::lexical_cast. 3 using boost::foreach 4. Usin he boost::serialization library. The std::wstring doesn't ned to be output to a file. Any advice apreciated. Sean.

What about the sequence assignment capabilities of basic_string itself, like this: std::wstring from_vector(const std::vector& src) { return std::wstring(src.begin(), src.end()); } ? For already existing std::wstring objects you could use it's assign overload that accepts an input iterator pair. HTH & greetings from Bremen, Daniel Krügler
