赫赫，找到代码了并且方便Post，就Post出来了：
更改IE代理服务器设置，不重新启动IE，代码如下：
但如何设置某种协议为一特定地址呢，BYPASS参数怎么用?
其实在proxyserver中http=205.207.118.51:80;https=205.207.118.51:80;gopher=205.207.118.51:80;socks=205.207.118.51:80是分别设置,
如果只有地址和端口则是所有协议使用相同地址
///Coder:Kingron
function ChangeProxy(const Proxy, Port,ByPass: string; const bEnabled: boolean = True): boolean;
var
reg: Tregistry;
info: INTERNET_PROXY_INFO;
Fproxy:string;
begin
Result := False;
FProxy:=Format('%s:%s',[Proxy,Port]);
reg := Tregistry.Create;
try
reg.RootKey := HKEY_CURRENT_USER;
if reg.OpenKey('/Software/Microsoft/Windows/CurrentVersion/Internet Settings', True) then
begin
reg.Writestring('ProxyServer', Fproxy);
reg.WriteInteger('ProxyEnable', integer(bEnabled));
info.dwAccessType := INTERNET_OPEN_TYPE_PROXY;
info.lpszProxy := pchar(proxy);
info.lpszProxyBypass := pchar(ByPass);
InternetSetOption(nil, INTERNET_OPTION_PROXY, @info, SizeOf(Info));
InternetSetOption(nil, INTERNET_OPTION_SETTINGS_CHANGED, nil, 0);
// InternetSetOption(nil, INTERNET_OPTION_REFRESH, nil, 0);
// Sendmessage(HWND_BROADCAST, WM_SETTINGCHANGE, 0, 0);
Result:=True;
end
finally
reg.CloseKey;
reg.free;
end;
end;
