Function getSoftwareList(sHost)

Class SoftwareMeteringCLS
' 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
