Hello everybody,

I have written a MFC application that allows to run Python's scripts with
using Python/C API. All works perfectly, but I don't know how to break a
script execution on demand (something like pressing Ctrl+C in Python).
Suppose I have a script that simply execute an endless loop and I would like
to stop it execution by clicking a button in my application and then dump to
my application an iteration count. Here is an example script:

def main():
        i = 0
        while 1:
            i = i + 1
    except KeyboardInterrupt:
        print "Iteration: ", i


Is there any possibility to break a script execution from my application and
catch the exception? How to do it? I would be grateful for any
