article in codeproject is more than modifying registry.
BOOL SetConnectionOptions(LPCTSTR conn_name,LPCTSTR proxy_full_addr)
{
//conn_name: active connection name.
//proxy_full_addr : eg "210.78.22.87:8000"
INTERNET_PER_CONN_OPTION_LIST list;
BOOL bReturn;
DWORD dwBufSize = sizeof(list);
// Fill out list struct.
list.dwSize = sizeof(list);
// NULL == LAN, otherwise connectoid name.
list.pszConnection = conn_name;
// Set three options.
list.dwOptionCount = 3;
list.pOptions = new INTERNET_PER_CONN_OPTION[3];
// Make sure the memory was allocated.
if(NULL == list.pOptions)
{
// Return FALSE if the memory wasn't allocated.
OutputDebugString("failed to allocat memory in SetConnectionOptions()");
return FALSE;
}
// Set flags.
list.pOptions[0].dwOption = INTERNET_PER_CONN_FLAGS;
list.pOptions[0].Value.dwValue = PROXY_TYPE_DIRECT |
PROXY_TYPE_PROXY;

// Set proxy name.
list.pOptions[1].dwOption = INTERNET_PER_CONN_PROXY_SERVER;
list.pOptions[1].Value.pszValue = proxy_full_addr;//"http://proxy:80";

// Set proxy override.
list.pOptions[2].dwOption = INTERNET_PER_CONN_PROXY_BYPASS;
list.pOptions[2].Value.pszValue = "local";

// Set the options on the connection.
bReturn = InternetSetOption(NULL,
INTERNET_OPTION_PER_CONNECTION_OPTION, &list, dwBufSize);

// Free the allocated memory.
delete [] list.pOptions;
InternetSetOption(NULL, INTERNET_OPTION_SETTINGS_CHANGED, NULL, 0);
InternetSetOption(NULL, INTERNET_OPTION_REFRESH , NULL, 0);
return bReturn;
}
BOOL DisableConnectionProxy(LPCTSTR conn_name)
{
//conn_name: active connection name.
INTERNET_PER_CONN_OPTION_LIST list;
BOOL bReturn;
DWORD dwBufSize = sizeof(list);
// Fill out list struct.
list.dwSize = sizeof(list);
// NULL == LAN, otherwise connectoid name.
list.pszConnection = conn_name;
// Set three options.
list.dwOptionCount = 1;
list.pOptions = new INTERNET_PER_CONN_OPTION[list.dwOptionCount];
// Make sure the memory was allocated.
if(NULL == list.pOptions)
{
// Return FALSE if the memory wasn't allocated.
OutputDebugString("failed to allocat memory in DisableConnectionProxy()");
return FALSE;
}
// Set flags.
list.pOptions[0].dwOption = INTERNET_PER_CONN_FLAGS;
list.pOptions[0].Value.dwValue = PROXY_TYPE_DIRECT ;
// Set the options on the connection.
bReturn = InternetSetOption(NULL,
INTERNET_OPTION_PER_CONNECTION_OPTION, &list, dwBufSize);
// Free the allocated memory.
delete [] list.pOptions;
InternetSetOption(NULL, INTERNET_OPTION_SETTINGS_CHANGED, NULL, 0);
InternetSetOption(NULL, INTERNET_OPTION_REFRESH , NULL, 0);
return bReturn;
}
The usage is very straightforward:

//set proxy
const char* connection_name="Connection to adsl3";
SetConnectionOptions(connection_name,"62.81.236.23:80");
//disable proxy
DisableConnectionProxy(connection_name);

Existing Internet Explorer instances are notified by INTERNET_OPTION_SETTINGS_CHANGED and INTERNET_OPTION_REFRESH

不知道onega是否在这里有帐号，应该也给他加分。呵呵。
真是挺厉害的人啊，能经常请教他就更好了。

to masterz:
onega发表在codeguru.com的修改代理设置的源码，我看了，他自己都说只是修改了注册表，
如果是这样，需要重启IE才生效吧。
你给的地址，codeproject怎么上不去。：（

如何修改IP的arp表啊？哪里有相关知识？
这个网络休闲庄IP隐藏器软件我也找到过，不过没有联系方式，也没法了解如何作的啊。
MyIE的代理设置估计也是用的这个arp，它和IE的设置互相不干涉
