Question

如题，已经做了数字签名了，每次调用ocx控件在ie里还是显示安全警告，请问怎么解决？

不多解释了，自己照葫芦画瓢吧。
unit UpdaterXImpl;{$WARN SYMBOL_PLATFORM OFF}interfaceuses
  ComObj, ActiveX, LesUpdater_TLB, StdVcl, Windows;type
  TUpdaterX = class(TAutoObject,IObjectSafety, IUpdaterX)
  private
    FObjectSafetyFlags: DWORD;
  protected
    procedure Start; safecall;
    { IObjectSafety }
    function GetInterfaceSafetyOptions(const IID: TIID; pdwSupportedOptions,
      pdwEnabledOptions: PDWORD): HResult; virtual; stdcall;
    function SetInterfaceSafetyOptions(const IID: TIID; dwOptionSetMask,
      dwEnabledOptions: DWORD): HResult; virtual; stdcall;
  end;implementationuses ComServ, Main;function TUpdaterX.GetInterfaceSafetyOptions(const IID: TIID;
  pdwSupportedOptions, pdwEnabledOptions: PDWORD): HResult;
var
  Unk: IUnknown;
begin
  if (pdwSupportedOptions = nil) or (pdwEnabledOptions = nil) then
  begin
    Result := E_POINTER;
    Exit;
  end;
  Result := QueryInterface(IID, Unk);
  if Result = S_OK then
  begin
    pdwSupportedOptions^ := INTERFACESAFE_FOR_UNTRUSTED_CALLER or
      INTERFACESAFE_FOR_UNTRUSTED_DATA;
    pdwEnabledOptions^ := FObjectSafetyFlags and
      (INTERFACESAFE_FOR_UNTRUSTED_CALLER or INTERFACESAFE_FOR_UNTRUSTED_DATA);
  end
  else begin
    pdwSupportedOptions^ := 0;
    pdwEnabledOptions^ := 0;
  end;
end;function TUpdaterX.SetInterfaceSafetyOptions(const IID: TIID; dwOptionSetMask,
  dwEnabledOptions: DWORD): HResult;
var
  Unk: IUnknown;
begin
  Result := QueryInterface(IID, Unk);
  if Result <> S_OK then Exit;
  FObjectSafetyFlags := dwEnabledOptions and dwOptionSetMask;
end;
