If you're using a file upload box and submitting that form directly to your .exe, then there's probably not much you can do. In order to do this, I think you'll have to "intercept" the file. When the user submits the file, it goes to a PHP script that copies it somewhere. Then see if you can make an exec() call to the system and set the "REMOTE_USER" variable, somehow. I'm not sure on the syntax/possibility of that, it would depend upon your OS. Then make another exec() call to your C++ program and send it the path the the file that was already uploaded. Capture the output and show it to the user or do whatever you normally do. ---John Holmes...
