PROPERTYPUT fails due to invalid number of parameters expected. #1427
Description
Running on Python 3.7 with pywin32 225.
I'm trying to interface with SAP GUI Scripting read-write properties, but writing to properties gives me an error as it doesn't do PUTs correctly. I've traced the issue back to commit to fix #1199 where the return value is changed from invoke_type to varkind. I believe some kind of special typing should be done with regards to PUTs instead of just sending back varkind directly.
The error I'm encountering:
File "\lib\site-packages\win32com\client\dynamic.py", line 559, in __setattr__
self._oleobj_.Invoke(entry.dispid, 0, invoke_type, 0, value)
pywintypes.com_error: (-2147352562, 'Invalid number of parameters.', None, None)

Sorry for the delay - I've started looking at this and things are a bit of a mess around this code. I've added some comments about that and I'm slowly cleaning things up a little so I can re-understand how things work :) It might take me a bit longer to untangle and I've a few other commits queued up in that direction. Please let me know if you are able to help me test things when I get a little further along - thanks!

(oops - that was actually meant for #1641, but it's still relevant here, so 👍 )

I think I fixed this in af54b27 - please reopen if you still have problems after the next release.
