The problem is parsing 'SWbemServices.ExecQuery' optional method parameters.

Signature MSDN:
http://msdn.microsoft.com/en-us/library/aa393866%28v=vs.85%29.aspx

--- quote ---
The ExecQuery method of the SWbemServices object executes a query to retrieve
objects. These objects are available through the returned SWbemObjectSet
collection.

This method is called in the semisynchronous mode. For more information, see
Calling a Method.

For an explanation of this syntax, see Document Conventions for the Scripting
API.

Syntax
VB

objWbemObjectSet = .ExecQuery( _
  ByVal strQuery, _
  [ ByVal strQueryLanguage ], _
  [ ByVal iFlags ], _
  [ ByVal objWbemNamedValueSet ] _
)

Parameters

strQuery

    Required. String that contains the text of the query. This parameter cannot
be blank. For more information on building WMI query strings, see Querying with
WQL and the WQL reference.
strQueryLanguage [optional]

    String that contains the query language to be used. If specified, this
value must be "WQL".
iFlags [optional]

    Integer that determines the behavior of the query and determines whether
this call returns immediately. The default value for this parameter is
wbemFlagReturnImmediately. This parameter can accept the following values.
    Value    Meaning

    wbemFlagForwardOnly
    32 (0x20)
...  

    Causes WMI to return class amendment data with the base class definition.
For more information, see Localizing WMI Class Information.


objWbemNamedValueSet [optional]

    Typically, this is undefined. Otherwise, this is an SWbemNamedValueSet
object whose elements represent the context information that can be used by the
provider that is servicing the request. A provider that supports or requires
such information must document the recognized value names, data type of the
value, allowed values, and semantics.
--- quote ---

'strQueryLanguage' = optional, needs to be passed in between pair of empty
commands as next parameter is explicitly given

'iFlags' = optional, 48 = WBEM_FLAG_FORWARD_ONLY | WBEM_FLAG_RETURN_IMMEDIATELY
(-> forward-only enumerator)

'objWbemNamedValueSet' = optional, no passing needed (last parameter)
