Thanks, these references are really helpful, and I think I understand a lot more of the path using comtypes. Continuing with my pseudo code example-- this is what I think I should do:
-run GetModule() on the library, which should create the interface foo -Create a class implementing foo -Create object implementing interface foo -Pass the object to the other com function that will fire callbacks to it comtypes.client.GetModule('CLSID that contains foo') class myComObjClass(COMObject): _com_interfaces_ = [foo] def foo_OnFunc1(self, this, variable1): do some stuff on callback def foo_OnFunc2(self, this, variable2): do some other stuff o=myComObjClass() otherDispatchedComObject.FunctionThatNeedsInterface(o, otherInputs) What I'm not sure about is the step that creates the object. Before, when I tried using win32com, I thought I had to wrap a server to pass it-- this didn't work, so I could have been off the mark here. Does this look right? Is it really this easy? _______________________________________________ Python-win32 mailing list Python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32
