Question

求VB按时间PING一个IP，并且显示速度。

功能大概就像浩方，QQ对站平台房间速度检测那样

绿的就是很快，红的很慢，然后后面写出时间。

求原代码,或者方法。直接写这或邮箱

求大家帮我，编写成功追分，相信咱分多。
这个我也找到了，没实例，写的也不全啊。。。

这样的代码在网上非常的多，所以你可以使用百度好好的查一下，然后就可以得到你要的答案。

首先你要制定一个标准多少时间是快的标准，多少时间是慢的标准

（绿的就是很快，红的很慢，然后后面写出时间。）

然后判断返回的时间和你的标准进行比对，得出时间就可以了，关于速度的标

准，特别是某个站点的速度那是非常的困难，你得到时间就可以比较客观的知

道某个站点的速度了！！！
