[Other] Asp.Net_Ajax_PROGRAM DL : 0: 我的第一个chat room 是用ASP 3.0写的。程序比较简单，两个text box，用来处理页面上每秒刷新的信息。那时候，要想建一个真正的chat room，要用到Java Applet 或者 ActiveX control。基于HTTP的chart rooms都面临着一些跟我第一个chat room一样的问题。这些问题包括页面刷新导致的屏幕闪烁现象。但这个问题已经被AJAX解决了。 AJAX是JavaScript和 XML异步调用的结合。现在在server端用一些JavaScript代码就可以实现一个真正的chat room了。这篇文章不会介绍Ajax，并假设你已经对Ajax和ASP.NET的运用有一定了解。只是介绍如何用Ajax技术来创建一个基本的chat room。 -My first is a chat room with ASP 3.0 writes. Procedures are relatively simple, two text box, used to handle pages of information per second set. At that time, if we want to build a real chat room, have to use Java applet or ActiveX control.
