[python-win32] Unexpected exception in gateway method 'AddTypeLib' with own Active Script Host

[Johan Lindvall]

Hi,

We are sometimes getting the error below when running a Python script in our
app.

We are calling AddTypeLib on the IActiveScript interface.

It always works with VB-scripts and sometimes fails with Python.

What could be the problem?

Could you try executing win32com\client\makepy.py as a script (eg, from a
cmd-prompt), then select the typelib from the list that will be displayed,
and see if it works there? According to the traceback, win32com believes it
successfully generated the file, but then failed to locate it.

Mark.

Could you try executing win32com\client\makepy.py as a script (eg, from a cmd-prompt), then select the typelib from the list that will be displayed, and see if it works there? According to the traceback, win32com believes it successfully generated the file, but then failed to locate it.

Makepy.py works and generates code for the complete typelib (including
all methods). The generated python file is placed in win32com\gen_py.
By method code I mean code like this:

def Exit(self):
"""Exits the application"""
return self._oleobj_.InvokeTypes(58, LCID, 1, (24, 0), (),)

With AddTypeLib, the partial code for the typelib is placed in a
subdirectory of win32com\gen_py.With partial I mean that there is no
code generated for the methods.

If i delete the generated files and call AddTypeLib, it always fails.
If I call it when there is generated typelib data available, it works.

Thanks

The error was in our code.

IActiveScriptSite::GetLCID returned garbage (even though we used the
sample provided by Microsoft).
