title: Win32 GUI: resize a dialog
body: <p>I have a basic Win32 dialog-based application. How do I make it resize?</p>
  
  <p>If it was a window this would be possible by default (and it would fire WM_SIZE). I'm new to dialogs and I'm not able to figure out how to: 1. when mouse cursor hovers over the edge, it should change to IDC_SIZEWE or IDC_SIZENS, 2. just resize the dialog, I know how to position dialog's content.</p>
