分页<%
'-------------------------------------------
' 接口：
' 属性：
' a、tip：项目提示（如，“篇文章”）；
' b、tablewidth：跳转页导航宽度
' 方法：
' a、SetRsObj（）方法：设置ADODB.RECORDSET对象；
' b、ControlPages（）方法：显示跳转页导航（“上一页”、“下一页”……）
' c、SetParams（）方法：设置参数数组
' 范例：
' dim params(1,1)
' params(0,0) = "query" : params(0,1) = request("query")
' params(1,0) = "keyword" : params(1,1) = request("keyword")
' 该数组主要传递查询关键字（如字段关键字、时间等），第一维是参数名称，第二维是参数值：如下http://…….asp?topage=2&query=yes&keyword=a
'
' set PageCtrl = new CPageCtrl
' PageCtrl.SetRsObj (RS) '设置ADODB.RECORDSET对象，其中RS是已建立好的ADODB.RECORDSET，即所要控制的记录集

' PageCtrl.tablewidth = "100%"
' PageCtrl.SetParams params

' PageCtrl.DimPage (15) '分页定义，每页15条记录
