[python-win32] IActiveScript::AddNamedItem fails with exception

[David Manns]

Mark,

Tried doing that, but nothing comes out on the debug trace at all. Do I have
to uncomment or add any trace commands in any of the .py files, or should I
expect to see things appear on the console already?
 
Best regards,
David

I'd suggest you:

* Execute "python win32comext\axscript\client\pyscript.py -debug" - this
will re-register the engine for debugging.

* Execute "python -m win32traceutil" - this will start a process which is
capturing messages from the COM object now it is in debug mode.

* Attempt to create and use the engine - this should cause output to be
generated.

Given the error is E_FAIL and the pyscript engine doesn't specifically throw
that, I suspect you will see a traceback.  Another alternative is to use the
IErrorInfo interfaces (I think that is what they are called) to try and grab
more information at runtime.
