[python-win32] "Property '%s.%s' can not be set" on read/write attribute

[Mark Hammond]

I can't see docs for that property, but if it takes optional params, it might have been transformed to a SetRuleName() method.  You could try adding:

 

rule_obj. _print_details_()

 

and see what is dumped.  Finally, if you can use makepy, the generated file should make it clearer to see what is going on.

 

Cheers,

 

Mark

So I'm trying to automate some tasks with SMS, and I've run into a roadblock when creating new collection membership rules.  The code below is a method of a Collection object.  It's a rough draft, so don't worry too much about the top half unless you think it might be screwing something up.  My problem is that I go to create a new SMS_CollectionRuleDirect object (at the bottom of the code provided) and I get the following error:

 

>>> coll.AddMembershipRule(rule)
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "H:\p4rootw\lib\ops\sms.py", line 495, in AddMembershipRule
    rule_obj.RuleName = name
  File "C:\Python24\Lib\site-packages\win32com\client\dynamic.py", line 550, in __setattr__
    raise AttributeError, "Property '%s.%s' can not be set." % (self._username_, attr)

 

If you look in the SMS 2003 SDK v3.1 or here (http://www.microsoft.com/technet/prodtechnol/sms/sms2003/opsguide/ops_854m.mspx?mfr=true) you can see that the property is indeed Read/Write.  Is there any way to override this or some workaround that I can use to fix this?  I'm about ready to start hopping up and down in my office chair like an angry chimpanzee.

 

 

 

 

 

# This is a method of an sms.Collection object.

# self.parent.wmi_connection is an object created via wmi.WMI() with the 

#   namespace set to  <file:///\\server\root\sms\site_S01> \\server\root\sms\site_S01, 

#   and I can retrieve information fine, as well as add/edit Collection, 

#   advertisement, and other objects just fine.

# self.parent.db_connection is an object created via odbc.odbc(), connected to the SMS database
