Jon Thank you for your answer. I tried it with no success. However I tried with tst=cdll.LoadLibrary("f:\\scratch\\test2\\footst.dll") instead of tst=windll.LoadLibrary("f:\\scratch\\test2\\footst.dll")
and it runs now with no error message, I can't figure for now why, but it's great! This is motivating for going ahead. Regards Alex -- http://mail.python.org/mailman/listinfo/python-list
