title: C++: Best way to get Window Handle of the only window from a process by process id, process handle and title name
body: <p>I'm looking for the best way to get a Window Handle in the following situation:<br>
  I have the <strong>process id</strong> and <strong>process handle</strong>, I know the <strong>window titlename</strong> and I know that the process has <strong>only one window</strong>.  </p>
  
  <p>So how would I do it? <code>FindWindow</code>? <code>EnumWIndows</code>?</p>
