title: MFC "Warning: skipping non-radio button in group."
body: <p>When running an old MFC application in Visual Studio's debugger I've seen a lot of warnings in the Output window like the following:</p>
  
  <blockquote>
    <p>Warning: skipping non-radio button in group.</p>
  </blockquote>
  
  <p>I understand that in MFC you put radio buttons in groups to indicate which sets of radio buttons go together.  If I remember correctly you do this by setting the "group" property of the first radio button to true, and then set the rest of the radio buttons "group" property to false.</p>
  
  <p>I have three questions about this warning.</p>
  
  <ol>
  <li><p>How do you get rid of this warning? Do 
  you have to set the "group" property of all
  non-radio button controls to true to
  avoid this, or should you just set
  it for the first control after the
  last radio button?</p></li>
  <li><p>Is there an easy way to figure
  out what controls or dialogs have this problem?
  I could open each dialog and
  fiddle with it until the warning
  pops up.  This application has a lot of
  dialogs though, so it would be
  nice if there was an easier way.</p></li>
  <li><p>What negative behavior can occur if 
  you don't fix this warning? In other
  words, does this even matter?</p></li>
  </ol>
