//
//   URLAssocationDialog().  This function invokes the unregistered URL
//  protocol dialog box, providing a standard ui for choosing the handler for
//  an unregistered URL protocol.
//
//  The functions returns S_OK if the application is registered with the
//  URL protocol.  S_FALSE is returned if nothing is registered (a one-time
//  execution via the selected application is requested).
//
//  Parameters:
//   hwndParent -- A handle to the window to be used as the parent
//   dwInFlags -- A bit field of URLASSOCIATIONDIALOG_IN_FLAGS.  The
//                flags are:
//
//                  URLASSOCDLG_FL_USE_DEFAULT_NAME: Use the default Internet
//                   Shortcut file name.  Ignore pcszFile.
//
//                  URLASSOCDLG_FL_REGISTER_ASSOC: The application
//                   selected is to be registered as the handler for URLs
//                   of pcszURL's protocol.  An application is only
//                   registered if this flag is set, and the user indicates
//                   that a persistent association is to be made.
//
//   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
//               registered for its URL protocol.  If
//               URLASSOCDLG_FL_USE_DEFAULT_NAME is set in dwInFlags, pcszFile
//               is ignored, and a default Internet Shortcut file name is used.
//               pcszFile is only used for ui.
//   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.
//   ucAppBufLen -- The length of pszAppBuf's buffer in characters.

//   MIMEAssociationDialog().  Invokes the unregistered MIME content

//
//   This function does not perform any validation on the syntax of the

//  that the input MIME content type string is a valid content type.
//
//   The function returns S_OK if the MIME content type is associated
//  with the extension.  The extension is associated as the default
//  extension for the content type.  S_FALSE is returned if nothing is
//  registered.  Otherwise, the function returns one of the following
//  errors:
//
//  E_ABORT -- The user cancelled the operation.
//  E_FLAGS -- The flag combination passed in dwFlags is invalid.
//  E_OUTOFMEMORY -- Not enough memory to complete the operation.

//                 window of any posted child windows.
//   dwInFlags -- A bit field of MIMEASSOCIATIONDIALOG_IN_FLAGS.  The
//                flags are:
//
//              MIMEASSOCDLG_FL_REGISTER_ASSOC: If set, the application
//               selected is to be registered as the handler for files of
//               the given MIME type.  If clear, no association is to be
//               registered.  An application is only registered if this
//               flag is set, and the user indicates that a persistent
//               association is to be made.  Registration is only possible
//               if pcszFile contains an extension.
//
//   pcszFile -- A pointer to a string indicating the name of the file
//               containing data of pcszMIMEContentType's content type.
//   pcszMIMEContentType -- A pointer to a string indicating the content
//                          type for which an application is sought.
//   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.
