I couldn't run it!

me too

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)
