Web chat may seem common to all of us. Some makes us easy to put up chat on our personal homepage. While the trend goes this way, I was thinking of developing my own COM chat object with VB. Wait.. something troubling me. I don&#039t understand how to stream data to all connected users, refresh the object itself automatically to read from the input, and stream out again.. ok. these may seem low-level. my whole purpose of this post is to understand how web chat works behind the scene. The detail process. Or best, references or codes that can be refered to. Suggestions to download pre-made chat control not welcome here.. thanks . <BR><BR>
