how to convert from LPCSTR to LPCWSTR in c++

Question

Answer 1

Converting from char * has a nice sample

char *orig = "Hello, World!";
cout << orig << " (char *)" << endl;

// Convert to a wchar_t*
size_t origsize = strlen(orig) + 1;
const size_t newsize = 100;
size_t convertedChars = 0;
wchar_t wcstring[newsize];
mbstowcs_s(&convertedChars, wcstring, origsize, orig, _TRUNCATE);
wcscat_s(wcstring, L" (wchar_t *)");
wcout << wcstring << endl;

But like tenfour mentioned. Use generic text mapping if possible
