不知昨天怎么搞的，今天用电脑的时候发现，鼠标右击→新建中没有新建TXT文档了，这个怎么恢复？ 鼠标右键新建里“文本文档”没有了？桌面上鼠标右击选“新建”“文本文档”没了，怎么找回来？
网上看了一堆解决办法，发现都比较复杂，还要用工具、修改注册表什么的。下面发布一个最简单的解决办法，复制下面的代码：
reg add "HKEY_CLASSES_ROOT\.txt" /ve /d "txtfile" /f
reg add "HKEY_CLASSES_ROOT\.txt\ShellNew" /v "NullFile" /f
点击“开始”菜单→“运行”命令，在弹出的“运行”对话框中输入上面命令确定。两行代码需要复制、运行两次。
今天闲着没事给博客添加了一下在每页文章页面结尾添加版权声明的功能，下面和大家分享一下如何给自己的WordPress添加版权声明。
首先在自己的博客模板目录找到single.php文件，下载之后在single.php的合适位置添加以下代码：
文章来源：< ?php bloginfo('name'); ?>[” title=”< ?php the_title(); ?>“>< ?php the_permalink(); ?>
版权所有©非注明网络来源文章请在转载时以链接形式注明作者和原始出处！
另外我对这个版权区域稍微美化了一下，CSS也与大家一起分享吧： 阅读全文…

根据国务院文件，5.19-5.21为全国哀悼日，在此期间，全国和各驻外机构下半旗志哀，停止公共娱乐活动，外交部和我国驻外使领馆设立吊唁簿。5月19日14时28分起，全国人民默哀3分钟，届时汽车、火车、舰船鸣笛，防空警报鸣响。 中国部分网站将整站换成素装。并建议中国所有站点更换为素装。
为方便站点哀悼，特提供素装代码，以表哀悼。
使用方法：
最简单的把页面变成灰色的代码是在head 之间加
第一情况：把下面代码复制到你网页的
今天在网上找了一个运行代码的插件runcode soncy修改版
使用方法:
1,下载插件并上传到插件目录，安装激活。
2,到WP后台设置默认宽度和默认字号。
3,发布日志时的使用：
runcode width="720" height="100"
这样定义后输入框的宽度就是720像素，高度就是100像素了。
runcode width="720" height="auto" size="14"
这样定义后输入框的宽度就是720像素，字号14像素，高度就是自适应的了。
也可以使用run code][/run code标签
测试一下：添加到收藏夹和设为首页代码
