Hi Blagoj,

Depending on which version of Delphi you have, it may or may not have some examples.

Delphi 5 (and I think Delphi 6) includes a very simple chat demo that uses the standard socket components. In my case (Delphi 5), it is located in the directory <DELPHIBASEDIRECTORY>\Demos\Internet\Chat

Hope this helps as a start.
