继续提问：WinForm如何与网页进行聊天！

Question

上次提问还未解决：http://topic.csdn.net/u/20090809/21/fa79ffc2-5b38-4fac-a22d-35bd1ddb06ba.html如题：网页上的用户如何与软件上的用户进行（视频）聊天！
因为以后要扩展成视频语音聊天，所以不能存在数据库里！继续寻找高手。

Answer 1

视频，必须用Activex控件了，同一个控件，winform, webform都可以用，利用vc+directshow
开发，

Answer 2

得做ACTIVEX控件，就跟网页上的播放器一样。

Answer 3

考虑到没办法使用P2P模式，WEB-》》server 是没办法是用UDP通信协议的。我写个sample试试

Answer 4

晕啦，我还不会ACTIVEX =======>
找人写一个或找个现成的，如果没有一些经验，是很难写出来的．

Answer 5

FLASH,COM,asp.net实现在线视频聊天 
或用FMS
或使用NetMeeting
