Yes, if you write an app that runs on that remote machine, it can read and broadcast the IP address if you like. Of course, it needs somewhere to send it.

Format your grid to show those columns. This is basic stuff. You should buy a winforms book and read it, or try reading MSDN.

Just open port 110 on server via NetworkStream and then send text-commands to it. Wink | ;-)

It's that easy. That's why I said 'simple' text protocol.
If it's to simple use link[^]

What he's saying is, do your own work. He's told you how it's done, if you can't even try to do it based on this, then you should consider doing a programming course, so you can one day hope to be a programmer.

Well, I can program, AND I can spell. I can even use google. If I ask for help, I tend to first try to think for myself and ask questions where I tell people what I've tried instead of asking them to send me code. This does not make me 'god', but I guess it does make me working for a real wage in the real world, instead of being hired because I am cheap, by people who don't realise I am not worth it.

It looks to me like you're using some sort of third party library. What error you get, is still a mystery. No-one can help based on that lack of information.

Please read the sticky at the top of the thread "How to get an answer to your question". So far you have broken rules: 2, 4, 7 8 pretty close to breaking 11 and also the unwritten rule about not using textspeak in message boards.
99.9% of the people on the message boards are unpaid and helping as an act of altruism. We are not here to supply you with code, just helping to provide guidance. You should ask a specific question or ask about a specific fault, otherwise you aren't going to get a better answer than the ones you have.
