|
// PURPOSE: class CRegUtil
|
||
|
|
// Encapsulates access to system registry.
|
||
|
|
// This is intended as generic access to the registry, independent of any particular
|
||
|
|
// application.
|
||
|
|
//
|
||
|
|
// PROJECT: first developed as part of Belief Network Editing Tools ("Argon")
|
||
|
|
// Later modified to provide more extensive features as part of version 3.0 of the
|
||
|
|
// Online Troubleshooter (APGTS)
