Once the file has played, play it again.

What is the problem?

What does it mean, "already existing"? Do you have source code? You have to modify and rebuild it, because something which does not play audio just does not play it.

The title of this question does not describe what you seem to be asking. Use the Improve Question and clarify it.
As Philippe said, just play the file again (and again....). Put it in a loop.
--- Probably in a BackgroundWorker or else it may do nothing except play the file. ---
Edit: Oops! I didn't notice the C++ tag, so you don't have BackgroundWorker. You may need to spin up a new thread yourself.

I'm also disturbed by the mutually-exclusive statements 'already existing program' and 'I am trying to write'.
Are you in search of a way to implement audio file playing in C++? Or do you have problems with the logic of playing it continuously? Please clarify, and share the code you have so far so that we can have a bigger picture.

It is quite easy. Here is some example code from microsoft. You only need to build a loop in a thread with some breakup code for playing.

C++

//a global value, to access the loop 
bool stillRunning = true;
char * szFile  = "";//your dynamic path


while( stillRunning)
{
  hr = pGraph->RenderFile(szFile, NULL);
}

The referenced Microsoft article appears to contain enough information to solve the problem.
However...
If you're going to quote code from some other source, you need to include enough to correctly demonstrate the solution to the asked problem.
The RenderFile() method doesn't play the file, the Run() method does.
Also, you have nothing to wait for the file to complete before repeating.
The loop you've shown will run forever and accomplish nothing useful.
