如：OrderBy字段，当用户点击时就加1，
在给用户显示时按orderby从大向小显示。

1，生成密码的方式：自己加密+ md5或sha加密，对用户输入的密码进行自己加密，如加上字符，然后再用md5或sha加密，存入数据库中。或者用md5加密后取出一段内容存放到数据库中，比对时也是截取比对。
2，保留一个生成加密码的程序，以在密码找不到时直接更改数据库。
3，做一个密码初始化功能，当用户密码忘记时管理员可对其恢复到最初密码。

新增与修改做成一个页面，修改只是需要根据其它页面传入的参数来对页面的控件进行初始化。

有两个，一是按创建日期排序，一是按更新日期排序。
在做文章编辑时若按更新日期排序，则文章顺序会变个不停，不利于维护，最好的方式是按创建日期排序，即保证了时序性，又能有一个固定的顺序，不会变来变去。

charindex 查找是否存在某个字符

SELECT *

WHERE (Adddate >= ‘2009-8-10 00:00:00’)
AND charindex(‘lvshou99.com‘, href) > 0
order by referrer desc

select id, title from example where updatedate > (select updatedate from example where id =&id) and status = 1 order by updatedate limit 0, 1

注：Firefox不支持object classid, 故要用embed，focus2.swf见Gmail

pics :指定显示的图片
links:每张图片对应的连接
texts:在图片下方显示的文字。
&amp;? 就是&
在links中若想url带参，用%26,而不是&,也不是&amp;
?? ?flash中会将“&”符号当分隔符处理，这样URL地址就变得不完整了，解决方法是将URL中的“&”改成“%26”即可。

<object ….. >

? <param …/>

</object>这种，在firefox中显示不出来，

可以用：

<object …..>

? <embed …/>

</object>

因为<embed src=””/>本身就是flash标签，所有想要同时支持ie和firefox,直接用<embed src=””/>

<embed name=”movie” src=”flash?参数” width=”” height=”” bgcolor=”” menu=”false” wmode=”opaque” />
