使用XML+VBS技术在ASP中实现报表的打印

March 25,2004

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:reportdemoaspreport.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>
