Registry

Ok, If this is the wrong forum i'm posting in then please direct me to the right forum...

I was wondering, how would I GRAB a specific peice of information
from the registry from another computer (when they execute my application)
Then it would send me the ip of who I am requesting the registry info from (so I can connect to receive the information)
and deliver me the requested information which i'd grabbed

Read up on winsock...

Be sure and tell the user that you are sending infomation about them "back home" people get real annoyed about that kinda thing being done behind thier backs.
