How can I make my program influence other's activity/read other's data?
I'm really curious:)
Some example programs to show you what I mean:
Programs that check screen, and react, like:
- If "poke" appears on some screen section, program will "click" it.("facebook automatic poke" ;-) )
Automatic programs that do something, without any conditions
- Refresh site in firefox every 5 seconds
Programs that check for other programs' activity and react:
- If code::blocks started, open foobar and start playing music :)
Programs that send input to programs and react basing on their outputs:
- parental control programs
Basically, I would like to know how can I get have stuff like this done. It would be also great if there is some article/source saying how hacks/viruses influence other programs, and how can I detect it and fight it(like, fighting bots in games).
I think that's it. Sorry if this question has been already asked. I'm hoping for nice answers, and thank you all in advance :)
PS. I forgot what I originally had in mind - programs that allow to check for memory leaks got me wondering. So these also count to list. Thanks again :)
