title: Why am I not getting events for a checkbox click in a treeview control?
body: <p>In my MFC dialog, i have a tree view control with checkboxes. Clicking the checkbox does not raise the NM_CLICK nor the TVN_SELCHANGED events, which I had hoped it would do.</p>
  
  <p>How do I correctly determine when a checkbox is checked/unchecked in a tree view control?</p>
