关于用vc实现修改ie代理的问题
现在需要通过一个文本框要别人输入代理地址127.0.0.1：80 然后按确定按钮即可实现改变
void CIeproxyDlg::OnButtonSet()
{
UpdateData(FALSE);
CString str;
this-> GetDlgItemText(IDPROXY,str);//获得用户输入的代理
unsigned long nSize = 4096;
char szBuf[4096] = { 0 };
INTERNET_PROXY_INFO* pInfo = (INTERNET_PROXY_INFO*)szBuf;
pInfo-> lpszProxy = str;
if(!InternetSetOption(NULL, INTERNET_OPTION_PROXY, pInfo, nSize))
AfxMessageBox(_T( "设置代理失败 "));
}
老是设置失败 不知道为什么哦。。。

你先看看你注册表中是不是有对应的健
你贴完整点的代码看看？
我这里是有那个键值的
===============
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings]

long ret0=(::RegOpenKeyEx(HKEY_CURRENT_USER,data_Set, 0, KEY_WRITE, &hKEY));
.....
long ret1=::RegQueryValueEx(hKEY, "ProxyServer ", NULL, &type_1, owner_Get, &cbData_1);
因为楼是用KEY_WRITE属性打开hKey的，所以RegQueryValueEx（hKey,...）会出错，建议楼主把KEY_WRITE 改为 KEY_WRITE|KEY_READ 试试
