Yes I did. It produced the variant type unknown error as described in the
first post.
import win32api
import win32com.server.util
from win32com import client as w32Client
win32Client =
win32com.client.gencache.EnsureDispatch("{69072C2D-6ED1-4051-BF8D-70286A303CDD}")
s = "AL"
r = "On"
win32Client.scriptCmd(s,r)
Traceback (most recent call last):
File "<ipython-input-7-b7dc7ecf5817>", line 1, in <module>
win32CC.scriptCmd('s','n')

"C:\Users\Natchos\AppData\Local\Temp\gen_py\3.8\E07C24C7-56CE-409F-AB60-DC7EDE9D9888x0x1x0.py",
line 37, in scriptCmd
return self._oleobj_.InvokeTypes(216, LCID, 1, (3, 0), ((31, 1), (31,
1)),cmd
TypeError: The VARIANT type is unknown (0x0000001f)
I did mange to find a workaround using another package(comtypes) and
working with ctypes:
from comtypes import client as ctClient
import comtypes
import ctypes
AutoIPam = ctClient.CreateObject("ImagingWin.AutoIPam")
s = ctypes.c_wchar_p(cmd)
r = ctypes.c_wchar_p(param)
AutoIPam.scriptCmd(s,r)
This version does work and does not throw an error. I can confirm the
instrument responds to the commands sent thusly.
