"Broken" is too harsh of a word. What you're seeing here is more or less an impedance mismatch between two very different interfaces. The Python dir() function knows about Python objects living in the Python object space. COM objects live in an entirely different space. Python, being cross-platform, doesn't have any internal knowledge about COM, which is strictly a Windows concept. The win32com code does its best to provide a bridge between those worlds, by providing a simulated Python object that satisfies most of the Python object requirements, but proxies its activities to the COM object it is wrapping. In the case of early binding, the only way win32com can do that is by parsing the TLB to figure out the object layout. If you look at the Python file generated by makepy, do you see the properties there? One interesting side note is that COM doesn't really have the notion of properties, because many languages don't support them. When an object supports a Color property, that's actually implemented by having methods called get_Color and set_Color. You might see if those are in the makepy file. > Note that both member functions and variables are present.

You do need to remember that you're not really looking at a COM object instance. You're looking at a win32com proxy that is communicating with the COM object. It's doing the best it can with the information it can extract, but if the TLB doesn't include everything, makepy can't make it up. > Given that I am trying to interact with Autodesk Inventor, and 90% of > the functionality of the COM interface is via properties, this is > quite frustrating!

Check the makepy file and see if they are present. -- Tim Roberts, t...@probo.com Providenza & Boekelheide, Inc. _______________________________________________ python-win32 mailing list python-win32@python.org https://mail.python.org/mailman/listinfo/python-win32
