Okay... it's been a while since i last posted a question here, but... now i ran into biiiiig problems. The problem i have to solve is somewhat like this: I have to design an UI which is similar to the one in Windows messenger(basic funcionality - only to send messages and files) through a local area network. Every computer on the network will have this program installed and i will have one server to configure and to transmit messages. the happy part of the problem is that the server is not my responsibility... So ... i drag a few textboxes, buttons... and i have the User Interface. I enable drag&drop for the textboxes (just like in Y!M) and... now comes the problem(s). How do i transmit the messages to the server (identified by an IP), maybe through some port? The message format is not one of my concerns, but... i guess sending data unencrypted over the web is not such a good thing (so i would need a way to encrypt data). How do i listen to some ports of the LAN for incoming messages from the server? How do i send files over the IP protocol? I think it is all about a transaction, but i have never done anything like this before (oh, i did! ... but that was on a ... serial port!). Thanks a lot for even trying to understand me! Any other ideas would be appreciated! Thanks a lot again!
