[pywin32-bugs] makepy.py generates incomplete class for a COM interface

[Vladimir B. <no...@gm...>]

Hello,

I think makepy/gen_py generates incomplete information for LabVIEW
8.6. Some functions available if late binding is used are unavailable
with early binding.

According visual studio COM object browser, the LabVIEW container
defines an Application class and an _IApplication interface with the
same set of functions and properties. Makepy correctly generates a
class for Application, but most of the methods are missing from the
_IApplication class. For example the GetVIReference function is
missing (see snippet at the end). GetVIReference works, however, if
late binding is used.

This problem is solved if I replace in the python file generated by
makepy "class _IApplication(DispatchBaseClass):" with "class
_IApplication(Application):", since the Application class has all the
methods.

Is this really a bug or am I doing something wrong?

Thanks,
