I have my Addresses in the Text Document formatted a specific way.

Example: 255.255.255.255:1080@SOCKS4

I'm trying to get all three different pieces of information and store them. I also want to make sure all pieces of information have been entered, as well as check for any formatting errors, maybe tell the user what line it was on etc..

However, i really have no idea how to do this... i was experimenting with some input.split but that just did not work out how i was hoping...

Thanks
