Well, then my next guess is the use of the Variant module (because no
error is thrown from OLE).
Some OLE calls require to be cast of a certain type before they work.
use Win32::OLE::Variant;
my $nodes = Variant(VT_ARRAY|VT_VARIANT, 0);
#I might also try VT_VARIANT or VT_ARRAY|VT_BSTR instead of
VT_ARRAY|VT_VARIANT
#then
my $objChildGroups = $objGetRoot-GetChildNodeGroups($nodes, TRUE);
Play around with this... I'm not the greatest Variant script writer
here, to know exactly which combination will work (if this is it) based
on the object type as I've only run into this a few times before, but
you can get examples from your perl install here (depending on your perl
build version) of similar options to try and all the VT_* types:

Re: WIN32::OLE WMI Out params
I haven't followed your thread closely, but it seems like the relevant
bits from your first link are these:
my $objSecDescriptor = Win32::OLE::Variant- new (VT_DISPATCH|VT_BYREF);
my $retval =
$objDirectorySecSetting-GetSecurityDescriptor($objSecDescriptor);
..which seems to be filling the $objSecDescriptor with an out param.
If your out param is an array, you might need to add VT_ARRAY to the
variant flags when you create it. Does something like that work for you ?

Some OLE calls require to be cast of a certain type before

my $nodes = Variant(VT_ARRAY|VT_VARIANT, 0);
My apologies here.. I think that I misstated the way to call it.
Put this at the top somewhere...
use Win32::OLE::Variant;
Add the following before your GetChildNodes call. Thanks go to Michael
Ellery for making me see that mistake as I did not test this code before
sending it off.
my $nodes = Win32::OLE::Variant-new(VT_ARRAY|VT_VARIANT, 0);
By adding this before your GetChildNodes call, you should be all set
(Variant-wise)
However, before you give up after trying the above call (if it does not
work as stated above), I would replace:
VT_ARRAY|VT_VARIANT
With
VT_VARIANT
And also try.. (if the previous does not work)
VT_ARRAY|VT_BSTR
And lastly try his example from the SecurityDescriptor call..
VT_DISPATCH|VT_BYREF
...in my code above.
As well, you might try sticking the VT_BYREF as another ORed option to
each of the above examples like in Michael Ellery's example.. i.e.
VT_ARRAY_|VT_BSTR|VT_BYREF or VT_VARIANT|VT_BYREF or
VT_ARRAY|VT_VARIANT|VT_BYREF

so, it looks like your Dumper statement is indicating a valid object in

I don't know the answer, but from my limited Perl/OLE experience, my
first guess would be that the function would want to return an OLE
container object in the output parameter, and so would expect it to be a
reference to a scalar. For example:
my $nodes;
use constant TRUE = 1;
my $objChildGroups = $objGetRoot-GetChildNodeGroups(\$nodes, TRUE);
print Child Group Count: . $objChildGroups . \n;
print @arrNodes . \n;
If I am right, and I may well not be, this would probably need to be
something like:
for my $obj (in $nodes) {
print Name: $obj-{Name}\n;
}

Any help would be appreciated.
