title: Visual Studio: class wizard malfunctioning
body: <p>Several class wizard functions aren't working, most of which I don't need very badly, but not being able to add classes to MFC controls is a big problem. I have an MFC dialog project going on, and whenever I try to, say, add a function to a class I just get "The operation could not be completed"--not very helpful. If in the resource view I right-click on a dialog and select "Add Class..." nothing happens.</p>
  
  <p>I have Microsoft Visual Studio 2005 w/SP1. I'm running WinXPHESP3 32-bit.</p>
  
  <p>BTW, this project was imported from VS 6.0, so I've got a bunch of things lying around like <code>AFX_MSG_MAP</code>, which I'm starting to suspect is useless and maybe interfering.</p>
