这里是ctrl+enter和alt+s的代码 自己查下键盘的ascii码再换就行
14.让层不被控件复盖代码:

<div z-index:1><object ***></object></div> ＃ 后面
<div id="layer2" style="position:absolute; top:40;width:400px; height:95px;z-index:2"><table height=100% width=100% bgcolor="#ff0000"><tr><td height=100% width=100%></td></tr></table><iframe width=0 height=0></iframe></div>

数据库查询中的特殊字符的问题
在进行数据库的查询时，会经常遇到这样的情况：
例如想在一个用户数据库中查询他的用户名和他的密码，但恰好该用户使用的名字和密码中有特殊的字符，例如单引号，“|”号，双引号或者连字符“&”。
例如他的名字是1"test，密码是a|&900
这时当你执行以下的查询语句时，肯定会报错：
sql = "select * from securitylevel where uid="" & userid & """
sql = sql & " and pwd="" & password & """
因为你的sql将会是这样：
select * from securitylevel where uid="1"test" and pwd="a|&900"
在sql中，"|"为分割字段用的，显然会出错了。现在提供下面的几个函数 专门用来处理这些头疼的东西：

cleft(string, length) 返回指定数目的从字符串的左边算起的字符，区分单双字节。
如：
dim mystring, leftstring
mystring = "文字测试vbscript"
leftstring = cleft(mystring, 10)
返回 "文字测试vb"。
myrandc(n) 生成随机字符，n为字符的个数
如：
response.write myrandn(10)
输出10个随机字符
myrandn(n) 生成随机数字，n为数字的个数
如：
response.write myrandn(10)
输出10个随机数字
formatquerystr(str) 格式化sql中的like字符串.
如：
q = request("q")
q = formatquerystr(q)
sql = "select * from [table] where aa like '%"& q &"%'"
getrnd(min, max) 返回min - max之间的一个随机数
如：
response.write getrnd(100, 200)
输出大于100到200之间的一个随机数

数据库查询中的特殊字符的问题
在进行数据库的查询时，会经常遇到这样的情况：
例如想在一个用户数据库中查询他的用户名和他的密码，但恰好该用户使用的名字和密码中有特殊的字符，例如单引号，“|”号，双引号或者连字符“&”。
例如他的名字是1"test，密码是a|&900
这时当你执行以下的查询语句时，肯定会报错：
sql = "select * from securitylevel where uid="" & userid & """
sql = sql & " and pwd="" & password & """
因为你的sql将会是这样：
select * from securitylevel where uid="1"test" and pwd="a|&900"
在sql中，"|"为分割字段用的，显然会出错了。现在提供下面的几个函数 专门用来处理这些头疼的东西：
