name: Elliot Viewer - Chicago Viewer Utility Cloned from the IFAX Message Viewing Utility
file: viewerob.h
comments: Class definitions for Viewer and ViewPage Objects. These objects are interface wrappers for the original IFAX viewer C code. All of the viewer's static variables and whatnot are collected here so that multiple independant viewers can be created to support multiple open documents/pages. The innards of the viewer objects are essentially the same as the original except for necessary fiddles to allow functions to get at things that used to be static but are now private object data. The original innards just scream to be converted to C++ but time constraints didn't allow that... If a struct or occasional whatnot seems a bit clumsy it is probably a relic leftover from the above original clone code. It works... NOTE: This header must be used with the LARGE memory model ---------------------------------------------------------------------------- Microsoft Corp.
