Help Required: How to call .vbs file from .php file?

Hi, I am in desperate need of some help in calling a vbscript file from a php file. I have searched high and low and have come up with nothing that will do it. I have found one example of a html file, which will call a vbscript file when the html file is double-clicked, but wont work if the file is viewd from the http://localhost. I really need a solution to this problem, any help you could offer would be appreciated greatly. Thanks, Laura
