Re: Working with COM objects

[MadraghRua]

Alright, I had a deeper look into Win32::OLE and came across the following

$tool->LetProperty('Molecule',$data);
$tool->setProperty('Molecule, $data);

So it turns out that the LetProperty method loads the $data instance into the Molecule attribute of the $tool instance. I'll be looking more closely at this to understand why this worked over the previous syntactic sugars that i was using.

I hope this node helps someone else in the future

In Win32::OLE property assignment using the hash syntax is equivalent to the Visual Basic Set syntax (by reference assignment):

        $Object->{Property} = $OtherObject;

corresponds to this Visual Basic statement:

        Set Object.Property = OtherObject

To get the by value treatment of the Visual Basic Let statement

        Object.Property = OtherObject

you have to use the LetProperty() object method in Perl:

        $Object->LetProperty($Property, $OtherObject);

LetProperty() also supports optional arguments for the property assignment. See OBJECT->SetProperty(NAME,ARGS,VALUE) for details.
