'  
' 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...

'   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.
