菜鸟学堂：
一、前言
asp在电子商务上应用广泛，报表的处理又有一些麻烦。本文介绍了在asp中利用
本人写的report server page脚本解释器实现报表的显示、打印。
二、准备工作
(1)安装visual reprort design软件
visual report design是本人写的一个免费的报表设计器，程序的发行只需要
安装一个控件即可。
想要的网友可以到http://go.163.com/reportpro/ 下载
(2)设计报表
通过visual report design 的可视化界面可以生成报表的脚本:mxb.rsp。
三、实现报表的打印、显示
下面是调用的文档:
printmx.asp
<%option explicit%>
<%
dim reportname,ret
dim reportatl
dim name
set reportatl=session("reportatl")
reportname=server.mappath("mxb.rsp")
ret=reportatl.xmltovbs(reportname)
if ret=-1 then
response.write reportatl.errormsg
response.end
end if
reportname=server.mappath("mxb.vbs")
ret=reportatl.doscript(reportname)
if ret=-1 then
response.write reportatl.errormsg
set reportatl=nothing
response.end
end if
set reportatl=nothing
%>
<html>
<object id=reportatl classid="clsid:d3f064e5-f4c0-4c52-9e7f-263d96b7ea11" codebase="report.cab#version=1,0,0,1">
</object>
<script language=vbscript>
dim ret
ret=reportatl.doprintreport("mxb.zcg")
if ret=-1 then
msgbox reportatl.errormsg
end if
</script>
</html>
用visual report design 产生的报表脚本mxb.rsp：
<?xml version='1.0' encoding='gb2312' ?>
<!doctype report system 'print_report.dtd' >
<report name='报表'>
<report_script>
dim rs,con,sql,lsh
dim temp
set con =createobject("adodb.connection")
con.connectionstring = "dbq=c:/report/demo/asp/report.mdb;driver={microsoft access driver (*.mdb)};"
con.open
set rs =createobject("adodb.recordset")
sql="select * from cj,student where cj.id=student.id "
rs.open sql,con,1,3
</report_script>
