dcef文件下载--程序节排坑二

ChromiumBeforeDownload中如果调用其他窗体文件做show操作，程序关闭时会内存释放错误，改用消息处理：

         PostMessage(MianHandle,Framme_ShowMyTAB_LJK,0,Cardinal(pMes));
        while sshow='' do
        begin
           Application.ProcessMessages;
           Sleep(50);
        end;
        TempFullPath:=sshow;

procedure TBrowserFrame.Chromium1DownloadUpdated(Sender: TObject;
  const browser: ICefBrowser; const downloadItem: ICefDownloadItem;
  const callback: ICefDownloadItemCallback);
var myshowinfo:pshowinfo;
begin
   //这里new会自动释放？       

   New(myshowinfo);

end;
