Hi All, I want to be able to use the Runtime Callable Wrapper for the Excel application as I would in the CLR from C#. Maybe I am missing something because it does work partially. If I get reference to Runtime Callable Wrapper for an Excel Application COM object then I can call its methods and properties like a normal clr object. However if one of the property is another COM object e.g. ExcelApp.Cells then it would need to a marshal.createwrapperoftype for that. How would I get it to work like comtypes (http://pythonhosted.org/comtypes/) but using the CLR wrapper instead of COM directly? Do I need to modify the python runtime in order to handle this use case or is there an easier way? Thanks, Phat
