Module Name:
SnapinNode.h
Abstract:
Header for the CSnapinNode class.
This is our virtual base class for an MMC Snap-in node.
As this is a template class and is all implemented inline, there is no SnapinNode.cpp for implementation.
Author:
Michael A. Maguire 11/6/97
Revision History: mmaguire 11/6/97 - created using MMC snap-in wizard mmaguire 12/15/97 - made into template class
