Hai Experts,

   How can I retreive the Internet Options (deatails about the proxy settings) found in the Internet Explorer through a Delphi application. Is there any windows API's to track this. Please help...

Hello

  you can do that easy by reading the proxy setting from IE setting in the registry

procedure TForm1.Button1Click(Sender: TObject);
var
  Reg: TRegistry;
begin
  Reg := TRegistry.Create;
  Reg.RootKey := HKEY_CURRENT_USER;
  Reg.OpenKey('Software\Microsoft\Windows\CurrentVersion\Internet Settings',false);
  Edit1.Text :=Reg.ReadString('ProxyServer');
end;

Best regards

That will only retrieve the settings for a LAN.  Try this - it will allow you to pass a connection name and retrieve the settings for it:

function GetIeProxyStatus (Connection : string; var FullProxyHost : string;
  var Enabled : boolean; var ProxyOverride : string) : boolean;
var
  List          : TInternetPerConnOptionList;
  Option        : array [0..2] of TInternetPerConnOption;
  Size          : Cardinal;
begin
  Size := SizeOf(TInternetPerConnOptionList);

  Option[0].dwOption := INTERNET_PER_CONN_PROXY_SERVER;
  Option[1].dwOption := INTERNET_PER_CONN_FLAGS;
  Option[2].dwOption := INTERNET_PER_CONN_PROXY_BYPASS;

  List.dwSize := SizeOf(TInternetPerConnOptionList);

  if Connection = '' then
    List.pszConnection := nil
  else
    List.pszConnection := PChar(Connection);

  List.dwOptionCount := 3;
  List.dwOptionError := 0;
  List.pOptions := @Option;

  Result := InternetQueryOption (nil, INTERNET_OPTION_PER_CONNECTION_OPTION,
    @List, Size);

  if Result then
  begin
    if Option[0].Value.pszValue <> nil then
    begin
      FullProxyHost := string(Option[0].Value.pszValue);
      GlobalFree (Cardinal(Option[0].Value.pszValue));
    end;

    Enabled := (Option[1].Value.dwValue and PROXY_TYPE_PROXY = PROXY_TYPE_PROXY);

    if Option[2].Value.pszValue <> nil then
    begin
      ProxyOverride := string(Option[2].Value.pszValue);
      GlobalFree (Cardinal(Option[2].Value.pszValue));
    end;
  end;
end;
