File Viewers

A file viewer is an OLE component object (not a compound document object) implemented inside a 32-bit in-process server dynamic-link library (DLL), which is associated, in turn, with the file viewer's class identifier. A file viewer provides the user interface for viewing a file. Menu items, a toolbar, and a status bar are standard parts of the file viewer interface. A file viewer can optionally add other functionality for further shell integration.
