That has nothing to do with what he wants, that link is for a tutorial of how to integrate Lua in C++, not how to send information to a software.
@myonlake, not sure if that would work, but you could create a server ( I don't mean a MTA server ) and you could use socket module from MTA Wiki to connect to it, that way you would send data to it and the software would retrieve that data. If the server wasn't online ( I mean, if the software wasn't open ) it would save data somewhere like a MySQL database and when the software opened, it would retrieve it.
