Hi,

I'm trying to get some information from SPSS using Win32::OLE. My problem is you need to pass a variant array of strings to the function, which is filled and returned. I'm using the following code: 

use Win32::OLE;

$spssapp = Win32::OLE->GetActiveObject('SPSS.Application');
$data = $spssapp->Documents()->GetDataDoc(0);

my $nvars = $data->GetVariableColumnWidths($cwidths);

This code works OK in SPSS Basic. In Perl the GetVariableColumnWidths function succeeds (LastError = 0 and $nvars returns the correct value) but nothing is returned in $cwidths.

I've experimented with creating $cwidths with Win32::OLE::Variant first using all of the following 

my $cwidths = Variant(VT_BTSR | VT_ARRAY, "");
my $cwidths = Variant(VT_BTSR | VT_ARRAY | VT_BYREF, "");
my $cwidths = Variant(VT_VARIANT | VT_ARRAY, "");
my $cwidths = Variant(VT_VARIANT | VT_ARRAY | VT_BYREF, "");

[download]
none of which work. Can anyone help?

Thanks,
Steve
