Hi,
I have a problem connecting to a COM server with a small test script using
python 2.3.5 as well as 2.4.1:
import win32com.client
from win32com.client import gencache
def main():
g1 = gencache.EnsureModule('{9C3BB401-114D-11D4-AC72-00105A4925FC}', 0, 1,
3)
theCADdy = win32com.client.Dispatch('CADdy.CADdy')
print repr(theCADdy) # =>
<COMObject CADdy.CADdy>
theCADdy = g1.ICADdy(theCADdy) # =>
<win32com.gen_py.CADdyCOM 1.3 (CADdy) Type Library.ICADdy instance at
0x21362568>
print repr(theCADdy)
v1 = theCADdy.VersionNo
if __name__ == '__main__':
main()
I got the following error message:
C:\Programme\Python\lib\site-packages\win32com\client\__init__.py in
__getattr__(self, attr)
453 if args is None:
454 raise AttributeError, "'%s' object has no
attribute '%s'" % (repr(self), attr)
--> 455 return self._ApplyTypes_(*args)
456
457 def __setattr__(self, attr, value):
C:\Programme\Python\lib\site-packages\win32com\client\__init__.py in
_ApplyTypes_(self, dispid, wFlags, retType, argTypes, user, resultCLSID, *args)
444 def _ApplyTypes_(self, dispid, wFlags, retType, argTypes, user,
445 resultCLSID, *args):
--> 446 return self._get_good_object_(
447 self._oleobj_.InvokeTypes(
448 dispid, 0, wFlags, retType, argTypes, *arg
s),
com_error: (-2147319779, 'Bibliothek nicht registriert.', None, None)
WARNING: Failure executing file: <Test3.py>
I have no idea what is going wrong with my test program. Connecting to MS Excel
is no problem. Can someone tell me how do I correctly use the pythonCOM
module. I have no problem connecting the CADdy COM server from VB and C++. Is
there anything wrong inside my COM type libraries?
With best regards
Johannes
