how? ICQ netdetect works.
Posted on 1998-10-17
My question is:
How does ICQ NDetect (or any other program with the same functionality) detect that you suddenly are connected to the intenet? (My ICQ NDetect activates when I log on to my computer. It does 'nothing' until you get connected to the internet or when you disconnect.)
I don't want any code, just let me now what technic it uses.
Does it use a timer that checkes for a connection every second? Is it this simple or can it be done any other way?
