Since this is a TEST code , the while(1); purpose is to stop code flow.

cout << "Function: " << __FUNCTION__ << endl;

I am finding out this setw does not always work

std::wstring GetStringW(HINSTANCE hinst, UINT id)
{
    std::vector<wchar_t> buffer(256);

    ::LoadStringW(hinst, id, buffer.data(), static_cast<int>(buffer.size()));
    return &buffer[0];
}
