ASP常用代码段之四

网络整理 - 09-08

1：asp获取网页源码

Or
GetHttpPage

2：asp将获取的源码转换为中文

3：asp用FSO打开文件

errorresume
isChkIntegeror
exit

5：asp判断数字是否为整形，过滤特殊字符串

then
        Ifnot
            Response.write
            Response.end
        Endif
    endthen
        ParaValue
            Response.end
        endif
    SRequest

6：asp一个MD5加密代码

Private03110310310310To&
Public0To

7：asp设置过期策略

Response.Expires =-1
Response.ExpiresAbsolute =1
Response.CacheControl =
Response.AddHeader
%>

8：用asp程序显示sql数据库所有表的名称

4：判断数字是否整形

errorresume
isChkIntegeror
exit

5：判断数字是否为整形，过滤特殊字符串

then
        Ifnot
            Response.write
            Response.end
        Endif
    endthen
        ParaValue
            Response.end

6：MD5加密代码:

Private03110310310310To&
Public0To

7：设置过期策略

Response.AddHeader

8：用asp程序显示sql数据库所有表的名称
