winapi - How to convert std::string to LPCWSTR in C++ (Unicode)

Question

I'm looking for a method, or a code snippet for converting std::string to LPCWSTR

Answer 1

Thanks for the link to the MSDN article. This is exactly what I was looking for.

std::wstring s2ws(const std::string& s)
{
    int len;
    int slength = (int)s.length() + 1;
    len = MultiByteToWideChar(CP_ACP, 0, s.c_str(), slength, 0, 0); 
    wchar_t* buf = new wchar_t[len];
    MultiByteToWideChar(CP_ACP, 0, s.c_str(), slength, buf, len);
    std::wstring r(buf);
    delete[] buf;
    return r;
}

std::wstring stemp = s2ws(myString);
LPCWSTR result = stemp.c_str();
