How do I construct a std::string from a DWORD?

Question

I have following code:

Tools::Logger.Log(string(GetLastError()), Error);

GetLastError() returns a DWORD a numeric

Answer 1

Since C++11

std::to_string() with overloads for int, long, long long, unsigned int, unsigned long, unsigned long long, float, double, and long double.

auto i = 1337;
auto si = std::to_string(i); // "1337"
auto f = .1234f;
auto sf = std::to_string(f); // "0.123400"

Yes, I'm a fan of auto.

To use your example:

Tools::Logger.Log(std::to_string(GetLastError()), Error);
