| I'm new to the mailing, so greetings all!
Welcome. As a word of warning, this is a relatively
low-activity list and I don't know what the overlap
is between this and the main python list. If you get
no response (or no solution) here, you might want
to try the Python list.
| I'm working on an application try to respond to events in Microsoft
| Access using Python and win32com.
| class AccessEvents
| def OnActivate(self):
| print "Hello from Access"
| return 1
|
| <snip>
| self. ac = Dispatch ("Access.Application")
| self. db = self. ac. NewCurrentDatabase ("d:\\pyhack\\foo")
| self. fm = self. ac. CreateForm ()
| self. ac. Visible = true
| self. fm = DispatchWithEvents (self. fm, AcEvents)
|
| blows out with
|
| self. fm = DispatchWithEvents (self. fm, AcEvents)
| File
| "D:\PYTHON22\Lib\site-packages\win32com\client\__init__.py", line
| 258, in
| DispatchWithEvents
| clsid = disp_class.CLSID
| AttributeError: 'NoneType' object has no attribute 'CLSID'.
Well, it's not clear from your code, but the third
parameter to DispatchWithEvents should be a *class*
and not an *instance*. Since AcEvents isn't defined
anywhere within your code snippet, it's hard to
see which it is, but just in case...
That said, I can't for the life of me see why that
would raise the error you're showing, but first
things first.
