Hi all,
I tried searching the mailing list archives for "com_record" but didn't
find anything relevant.
For context, I'm trying to access a COM interface defined in a .tlb file.
Here's a skeleton of the script I'm using to expose this interface:
import pythoncom
from win32com.client import gencache
lib_GUID = "{<GUID>}"
lib_major = 1
lib_minor = 0
lib_pyITypelib = pythoncom.LoadRegTypeLib(lib_GUID, lib_major, lib_minor)
lib = gencache.EnsureModuleForTypelibInterface(_lib_pyITypelib)
ccs = lib.CControlServer() # CControlServer is a CoClass
eid, *other = ccs.LoadExperiment(**path to file**) # Works
ccs.GetSoftwareInfo() # Fails with exception below.
ccs.GetSolvent(eid) # also fails
I can't dig down in the debugger to find the source of the exception, so
I'm hoping someone here can help!
Exception:
def GetSoftwareInfo(self, info=pythoncom.Missing):
<ipython-input-8-7304ad54d54a> in <module>
----> 1 ccs.GetSoftwareInfo()
