  • asp.net教程之使用XML+VBS技术在ASP中实现报表的打印

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>
