VB 修改 IP地地址

你要问的是不是以上三项在注册表中的位置,下面提供：

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces

项下有很多句柄你可以在里边找到不同的本地连接对应的句柄，在程序里进行修改就可以了,如果找不到，可以先在本地连接属性里修改tcp/ip协议的相应设置，然后到注册表里查找相应的数据就可以定位该位置了！源码这次就不给出了，就是修改注册表，和容易，您可以使用vb自带的函数，也可以使用wsh提供的脚本函数，当然也可以使用winAPI（比较复杂，要严格定义参数类型，即缓冲区，所以简单的修改不建议使用）。

希望您的问题能尽快解决！

vb.net怎样设置ie浏览器的代理服务器地址

建议你使用注册表的API进行修改

封装两个NET函数给你

private string GetReg(string RegPath)  取得注册表项内容

{

string str="";

RegistryKey hkml = Registry.LocalMachine; 

RegistryKey software = hkml.OpenSubKey("SOFTWARE",true); 

RegistryKey aimdir = software.OpenSubKey("krabs",true);

if (aimdir != null)

{

if (aimdir.GetValue(RegPath) != null)

str = aimdir.GetValue(RegPath).ToString();

if (str != null)

return str;

return null;

}

return null;

}

private bool SetReg(string RegPath,string Data)  //设置注册表内容

{

RegistryKey reg = Registry.LocalMachine;

RegistryKey software = reg.OpenSubKey("SOFTWARE", true);

RegistryKey aimdir1 = software.CreateSubKey("krabs");

if (aimdir1 == null)

return false;

aimdir1.SetValue(RegPath, Data);

return true;

}

如何在vb，net用程序修改ip地址

做exe程序获取本机IP地址用

System.Net.Dns.GetHostByName(System.Net.Dns.GetHostName()).AddressList

做web程序获取客户端的IP地址用

HttpContext.Current.Request.ServerVariables（"REMOTE_ADDR"]）
