求助！一个小问题，请大家帮忙谢谢！

[lt213]

我现在在做一个故障处理反馈的系统遇到了一个问题，就是怎么样可以实现网络里面2台电脑通过IP地址进行消息互发？前台用户发了一个故障信息过来我要在后台马上弹出提示框，如果后台不应答的话就要不停的发出提示信息。请问这个用DELPHI怎么实现？谢谢！请大家帮帮忙！分数不够可以再加！

局域网内直接使用信使服务就可以了
net send remotecomputer xxxx
remotecomputer 远程机
xxxx 要发送的信息

请在详细点好不好咯!谢谢!

怎么不详细了呢。。　
　　\Demos\Internet\Chat 看看啊。。。

[xiamang]

用ServerSocket　ClientSocket　来编程，具体的程序例子，网上很多。。

[xiamang]

最好的例子是Delphi 自带的　\Demos\Internet\Chat 。看看就知道如何做了。。

还有更具体点的吗？谢谢！

就是用ServerSocket　ClientSocket

去精华区找一找，或者有.

在Form 上放一个ServerSocket 和一个ClientSocket 设置两个控件的端口,设置ClientSocket的Address或者Host,将两个控件的Active 设置为True;
当ClientSocket发送数据的时候,用SendText(msg:sting);serverSocket 的 OnClientRead()事件接受到CLientSocket 发送的数据时,判断数据的有效性，即可弹出窗口。
