Running an exe file from shell command
I need some advice on running an exe file through a shell command on a Windows server.A potential client wants to create a site that calls an Windows exe executable to generate a custom graphic file for customers. The executable would be called with a shell command in response to a form post by the customer.
I have some basic questions about doing this:
1. I'm assuming shared web host is out of the question. But are there any VPS hosts that I could use for this site, or must I use a dedicated server for this site?
2. How difficult is this to do? Am I heading towards major headaches?
3. What security issues do I need to watch for?
4. Is there anything else I should consider or check on before I take on this site?
Thanks in advice for any advice.
