This probably isn't the best place to post questions of this nature.
You should try the wxPython's user group or the pywin32 group.

http://wxpython.org/maillist.php
http://mail.python.org/mailman/listinfo/python-win32

Is the event you're trying to cancel caught by wxPython's event
handlers or win32?
