//
//   pcszFile -- The name of the Internet Shortcut file whose URL's protocol
//               requires a protocol handler.  Before a verb, like "open", can
//               be invoked on an Internet Shortcut, a protocol handler must be

//   pcszURL -- The URL whose unregistered protocol requires a handler.
//   pszAppBuf -- A buffer to be filled in on success with the path
//                of the application selected by the user.  pszAppBuf's
//                buffer is filled in with the empty string on failure.
