I just tested under comtypes 0.3 and 0.4 with Autocad 2008. I get this
exception for both when using CreateObject:
######################################################################
>>> acad = client.CreateObject("AutoCAD.Application")
Traceback (most recent call last):
File "<input>", line 1, in <module>
File "D:\Python25\Lib\site-packages\comtypes\client\__init__.py", line 203,
in CreateObject
return _manage(obj, clsid, interface=interface)
File "D:\Python25\Lib\site-packages\comtypes\client\__init__.py", line 171,
in _manage
obj = wrap(obj)
File "D:\Python25\Lib\site-packages\comtypes\client\__init__.py", line 122,
in wrap
typeattr = tinfo.GetTypeAttr()
File "D:\Python25\Lib\site-packages\comtypes\typeinfo.py", line 262, in
GetTypeAttr
return _deref_with_release(self._GetTypeAttr(), self.ReleaseTypeAttr)
COMError: (-2147418111, 'Call was rejected by callee.', (None, None, None, 0,

I think this happens because comtypes is trying to talk to Autocad before it
is finished its post startup initialization (loading modules, CUI, lisp
files).
Using client.GetActiveObject on the other hand successfully generates the
Autocad modules and returns a pointer to the first running instance. It
doesn't work if Autocad isn't running though.
BTW Thomas: I had to switch back to version 0.3.3 because something broke
between that version and the current. When I try to get a pointer to
Microstation under 0.4.1 I get this:

Something to do with the safearray refactor?

Check out the new SourceForge.net Marketplace.
It's the best place to buy or sell services for
