Works well for me. It's an interesting bit of code!

Just an update here in case anyone is trying to run this in Visual Studio 2013.
Before building a project, go to the Project Properties > General. Switch Character Set to "Use Multi-Byte Character Set". This will stop any errors related to "Cannot convert char[] to LPCWSTR" since it is by default looking for unicode and not multi-byte strings.

More info about this here: https://social.msdn.microsoft.com/Forums/vstudio/en-US/c1b08c0a-a803-41c3-ac8c-84eba3be1ddb/faq-cannot-convert-from-const-char-to-lpctstr

without this code i get "Cannot convert char[] to LPCWSTR"

    wchar_t *convertCharArrayToLPCWSTR(const char* charArray)
    {
        wchar_t* wString=new wchar_t[4096];
        MultiByteToWideChar(CP_ACP, 0, charArray, -1, wString, 4096);
        return wString;
    }

and change "search_path" to this :
convertCharArrayToLPCWSTR(search_path)
