<DIV>This appears to be related to the bug logged at <A
title=http://bugs.python.org/issue3905
href="http://bugs.python.org/issue3905">http://bugs.python.org/issue3905</A>. My
app makes use of subprocess to obtain various bits of data that it then parses
and displays in its UI. For what it’s worth, injecting the trace module
into my frozen app causes no output to appear at all in the app itself, and
returns the error above; the trace module seems to trigger the suprocess bug.
However, it seems to have no bearing at all on the failure of VBScript to create
a COM object from my application, and the debugging output logged to my
stdout/stderr file did not yield any insight on that. </DIV>
<DIV> </DIV>
<DIV>I investigated whether running the mainloop() in the app might interfere
with the application receiving the COM request from the Windows Script Host, but
commenting out the mainloop only caused the app to crash (since Tkinter apps
require a mainloop to run). </DIV>
<DIV> </DIV>
<DIV>The bottom line of all this investigation is that I am no closer to
understanding why my Tkinter app does not respond to the CreateObject request
from VBS. It appears that those requests simply disappear into a black hole. It
also appears that integrating a GUI toolkit with its own event loop in Python
may not be very practical with a COM server (see <A
title=http://trac.wxwidgets.org/ticket/12105
href="http://trac.wxwidgets.org/ticket/12105">http://trac.wxwidgets.org/ticket/12105</A>
for some other issues with wxPython and COM). Unfortunately, this means my
best option is probably to move ahead without COM support. </DIV>
