Module Name:
LogAbout.cpp
Abstract:
Implementation file for the CLoggingSnapinAbout class.
The CLoggingSnapinAbout class implements the ISnapinAbout interface which enables the MMC
console to get copyright and version information from the snap-in.
The console also uses this interface to obtain images for the static folder
from the snap-in.
Revision History:
mmaguire 11/6/97 - created using MMC snap-in wizard
