HI, To answer your questions, I run this on Windows. What is so weird is that when I do $a= shell_exec("C:\Inetpub\wwwroot\/test.exe -m$market -d$length"); echo $a; It works, and echoes everything as it is supposed to, and the file is also generated like I expected. However, the PHP file where I execute this from is in the same folder (which is why I thought using a . would work) Could anyone please tell me if this is only way Ito do this on a Windows machine? Thanks in advance, I think I am getting a little confused. Alice _________________________________________________________________ Search from any Web page with powerful protection.
