How to invoke an external application like an EXE file from zope.

Start by giving your message a meaningful subject line. Continue by not attaching pointless gifs to your message. Further continue by not posting in HTML to a non-HTML list. Finally, look at external methods and python's os.system or popen3 or popen4 functions. Alternatively, front your Zope with Apache and call your .exe as a CGI by URL, if you so require... cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk
