如何用vb.net控制上网时间
孩子马上要放暑假了，电脑游戏一玩就是几个小时，请问高手应该怎样用vb统计上网时间，设置为每天上网1-2个小时后自动断网，不胜感激。 --------------------编程问答-------------------- 装绿坝花季护航，虽说这个软件次了点，但是总比你自己写的强。而且政府花4000万买断了，使用是免费的。 --------------------编程问答-------------------- 我觉得你应该自己告诉他控制好时间，最恨打着游戏突然就断线了。 --------------------编程问答-------------------- 你着父亲 做的 真够资格的 --------------------编程问答-------------------- 把相关的代码放在 window services 的项目代码里面
做一个后台服务 这样没词开机时间的时长都可以自己设置和定义
--------------------编程问答-------------------- 顶下楼上。 --------------------编程问答-------------------- 支持一下 4楼，直接控制电脑运行时间吧
