title: MFC Timer One-time Execute
body: <p>I'm programming in c++ using MFC.</p>
  
  <p>I want to make a piece of code execute after the UI has fully loaded, so I put it in a OnTimer callback and called SetTimer in the OnInitDialog. The problem is how to make that timer only execute once?</p>
  
  <p>Any help would be appreciated.</p>
