note 80772 rejected from function.exec by nlopess

Note Submitter: tungmingtommy at gmail dot com ---- Dear all, I am writing a PHP+MySQL program which can send SMS automatically to the users. I am using the Microsoft SMS sender to send SMS. When a command " smssender.exe [[/i] /p:65065110 /m:"hihi" [/u] [/l]] " is typed on the cmd.exe window, I can send a SMS. But I don't want to send it by typing this command every time but instead I want to do it with PHP. Is it possible? I know that some function like exec() which can execute an external programs. But I cannot do it with my Win XP laptop computer. I also heard that Win XP has prevent user programs to call cmd.exe directly, is it true? Please Please help!
