' Author: Branimir Petrovic
' Date: 6 Sept 2002
' Version: 1.0.3
'
' Revision History:
' 30 March 2002 V 1.0.0
'
' 08 April 2002 V 1.0.1
' Added error handling - if the target system is not present,
' or does not have WMI, getList(sHost) will return empty list.
'
' Added global function getSoftwareList(sHost) to be used
' from *.wsf scripts when caller script is JScript (since
' JScript can not instantiate VBS classes directly).
'
' 21 April 2002 V 1.0.2
' Replacing "[" with "(" and "]" with ")" in "DisplayName"
' Some strings like: [See Q311401 for more information]
' can cause troubles, therefore replacement.
'
' 6 Sept 2002 V 1.0.3
' Win2K's SP3 for Windows 2000 introduced slight (but silent)
' 'improvement' in a way registry provder's EnumValues method
' deals with empty keys. EnumValues method called against
' keys without any values (except the Default, empty value)
' will now return Null value (previously array of size 0 was
' returned). Added (previously unneeded) type checking...
'
'
' Dependancies:
' WSH 5.6
'
' Methods:
' - getClassName()
' - getVersion()
' - getList(sHost) sHost parameter can be computer name or IP address
' Enumerates all subkeys in:
' "Software\Microsoft\Windows\CurrentVersion\Uninstall"
' Returns array of strings, each string item containing:
' "DisplayNameKeyValue[ --Version: DisplayVersionKeyValue]"
'
' If sHost parameter is empty string or non-string value,
' function returns list of installed software on this host.
' Otherwise it will connect to host pointed to by sHost string
' (provided sufficient level of permissions)
'
' - getHostString() Returns name of the system or IP address
