shell 语句可以运行所有可执行文件,有没有什么语句或函数可以执行语句,就是在DOS编辑器下运行的语句可以用VB中的某些语句或函数运行.比如在DOS下输入IPconfig可以获得本地的IP,怎么实现在VB中按下某个按钮就显示自己的IP

当然可以。

PING一个IP地址(向它发送一个数据包并等待回应)

本例演示了怎样通过API的调用向一个IP地址发送一个包的数据并等待回音。
新建一个工程，添加一个标准模块，写入以下代码：

得到用户的IP地址

最快的方法是读取 Winsock 控件的 "LocalIP" 属性。

一、可以用API方式也获取，你自己查一下吧，我也忘了。
二、shell "ipconfig >a.txt"
然后打开这个a.txt文件看看

好像很复杂

回复5楼

好像不行,找不到文本文件

这只能针对某个,不能针对所有的,有没有针对所有的都可以的

打不到文件？
默认是C：盘的你的用户下的，你可以指定路径的啊

[此贴子已经被作者于2006-12-7 16:27:40编辑过]

我查了,查不到,如果是指定路径怎么写
shell "ipconfig >C:\Documents and Settings\PcrazyC\桌面\a.txt"这样写不行,还是找不到

shell "ipconfig >"C:\Documents and Settings\PcrazyC\桌面\a.txt""这样写又有语法错误

嘎嘎~，你要这玩意干什么用？
