There isn't a predefined VARIANT type for GUIDs, so I wouldn't know how this parameter needs to be passed by OLE Automation. Looking at the native interface is no use; you have to check the IDispatch interface to see what parameters foo() expects. Or does the application also define a GUID object? In that case you need to create an instance of that and pass a reference to it.
