title: Visual studio custom build step rule?
body: <p>Using Visual Studio 2008, When I add to a C++ project a file that is not <code>.c/.cpp/.h/.rc</code> or anything the IDE doesn't recognize a dialog pops up which asks me if I want to create a custom build step rule for this kind of files.</p>
  
  <p>Does anybody know how to get to this dialog without adding a file? I can't seem to be able to find in any of the menus.</p>

  <p>Edit: I know all about the <code>.rules</code> file. What I'm talking about is a GUI Dialog from within Visual Studio 2008 which allows you to create and edit these <code>.rules</code> files. This is the dialog I mentioned which pops up when you add a file with an unknown extension.</p>
