[C++] Create GUID

You can create GUID by using CoCreateGuid API.
I copy example source code from my reference article for memo as below.

#include "stdafx.h" #include <objbase.h> #include <string> using namespace std; wstring GetGUID() {     _TUCHAR *guidStr = NULL;     GUID *pguid = new GUID;     CoCreateGuid(pguid);     // Convert the GUID to a string     UuidToString(pguid, (RPC_WSTR*)&guidStr);     delete pguid;     return wstring(guidStr); } int _tmain(int argc, _TCHAR* argv[]) { wstring guid = GetGUID();     wprintf(guid.c_str());     return 0; }
