    server side C++ question

    I want to make an application that when azurues finishes downloads it sends a SMS through:

    http://www.onlinetextmessage.com/

    Though I dont know how to interact with ONLINE scripts, also I want it to be hidden, So that the user cant see it just incase the user is at the computer when it happens.

    Code:

    }
    and whole aplication is on

    I would think PHP or Python might be a better choice, but maybe I don't understand the problem.
