Elaborating, perhaps needlessly, on Corion's observations and questions:

• Is the server upon which the website is running the same machine as that where the executable runs?
• Do you need to capture (and perhaps process further) the output of the executable?

Did you read On asking for help and How do I post a question effectively?? If not, they may disabuse you of any belief that we would share your view that our solution(s) for your project is "urgent?"

Ask a clearly defined question; show that you've made some effort and you will almost certainly receive good help. Treat the Monastery as a "free code machine" and help, other than this sort of help, is less likely to appear.
