[Fwd: Re: [ctypes-users] Application error with Report Manager on exit]

[Werner F. Bruhin]

I am having the above problem with Report Manager.  Suspected that it 
had to do with ctypes but Thomas was so kind enough to have a look at it 
and thinks that it has to do with wx (see end of this message).

I hope that someone could look into this who has the know how and time 
to work with a wx debug build.

The problem does not happen using only Python code, but when the 
following two lines are e.g. in a OnButton Event the error does happen.

rm = ReportMan(r"c:\temp\bruhin\sample4.rep")
rm.preview()

Werner, I have tried that and can confirm the error you get.  However,
using this code:

from reportman import ReportMan

rm = ReportMan(r"c:\temp\bruhin\sample4.rep")
rm.preview()

the error does not occur.  So, I get the impression that the problem is
not in reportman.py, or in ctypes, but instead somewhere in wx or the
wx activeX wrapper.  Unfortunately, I don't have a debug build of wxPython,
so I cannot debug this further.

Hope that helps (but I'm afraid it will not).
