在进行ASP网站开发时,有时需在客户端调用MSSQL数据库的数据进行打印,若调用数据量小,可以通过在客户端运用FileSystemObject生成文件对象的方法实现打印,这里不再赘述。若需调用大量数据,可在客户端脚本中实例化RDS.DataSpace(Remote Data Service)对象,并采用远程提供程序通过ASP网站访问MSSQL数据库(设置成只能通过RDS Default Handler或自定义商业对象才能访问数据库,可保证数据库的安全),再在客户端实例化EXCEL.APPLICATION对象,把数据集中的数据写入EXCEL中,再进行保存或打印。代码如下:
<html>
<head>
<META content="text/html; charset=gb2312" http-equiv=Content-Type>
<title>客户端电子表格打印</title>
</head>
<body bgColor=skyblue topMargin=5 leftMargin="20" oncontextmenu="return false" rightMargin=0 bottomMargin="0">
<div align="center"><center>
<table border="1" bgcolor="#ffe4b5" style="HEIGHT: 1px; TOP: 0px" bordercolor="#0000ff">
<tr>
<td align="middle" bgcolor="#ffffff" bordercolor="#000080">
<font color="#000080" size="3">
客户端电子表格打印
</font>
</td>
</tr>
</table>
</div>
<form name="myform">
<DIV align=left>
<input type="button" value="Excel Report" name="report" language="vbscript" style="HEIGHT: 32px; WIDTH: 90px">
</div>
</form>
</body>
</html>
<script language="vbscript">
sub fun_excel()
Dim rds,rs,df
dim strCn,strSQL,StrRs
Dim xlApp, xlBook, xlSheet1
set rds = CreateObject("RDS.DataSpace")
Set df = rds.CreateObject("RDSServer.DataFactory","http://192.168.0.1") '192.168.0.1 为WEB服务器IP地址
strcn="provider=ms remote;remote server=http://192.168.0.1;handler=msdfmap.handler;data source=pubsdatabase;" '192.168.0.1 为WEB服务器IP地址
strsql= "getalljobs"
Set rs = df.Query(strCn, strSQL)
Set xlApp = CreateObject("EXCEL.APPLICATION") '注意不是:Server.CreateObject("EXCEL.APPLICATION")
Set xlBook = xlApp.Workbooks.Add
Set xlSheet1 = xlBook.Worksheets(1)
xlSheet1.cells(1,1).value ="职务表"
xlSheet1.range("A1:D1").merge
xlSheet1.cells(2,1).value = "job_id"
xlSheet1.cells(2,2).value = "job_desc"
xlSheet1.cells(2,3).value = "max_lvl"
xlSheet1.cells(2,4).value = "min_lvl"
cnt =3
do while not rs.eof
xlSheet1.cells(cnt,1).value = rs("job_id")
xlSheet1.cells(cnt,2).value = rs("job_desc")
xlSheet1.cells(cnt,3).value = rs("max_lvl")
xlSheet1.cells(cnt,4).value = rs("min_lvl")
rs.movenext
cnt = cint(cnt) + 1
loop
xlSheet1.Application.Visible = True
end sub
</script>
也可以实例化RDS DataControl,只需把以上部分代码进行修改:
set rds = CreateObject("RDS.DataSpace")
Set df = rds.CreateObject("RDSServer.DataFactory","http://192.168.0.1") '192.168.0.1 为WEB服务器IP地址
strcn="provider=ms remote;remote server=http://192.168.0.1;handler=msdfmap.handler;data source=pubsdatabase;" '192.168.0.1 为WEB服务器IP地址
strsql= "getalljobs"
Set rs = df.Query(strCn, strSQL)
修改为:
set DC = createobject("RDS.DataControl")
dc.ExecuteOptions =1 '设置成同步执行,可以简化下步代码
dc.FetchOptions = 1
With dc
.Server = "http://192.168.0.1"
.Handler = "MSDFMAP.Handler"
.Connect = "Data Source=pubsdatabase;"
.Sql = "getalljobs"
.Refresh
End With
set rs= dc.Recordset
修改文件MSDFMAP.INI(若在WIN98,C:\windows\msdfmap.ini;若在WIN2000,D:\winnt\msdfmap.ini;若在WIN2000 SERVER,D:\winnts\msdfmap.ini)。
[sql getalljobs]
Sql="SELECT * FROM jobs"
[connect pubsDatabase]
Access=Readonly
Connect="provider=sqloledb;data source=sql server;initial catalog=pubs;UID=userid;PWD=password"
打开注册表HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Services\W3SVC\Parameters\ADCLaunch 若无 RDSServer.Datafactory,请添加。本例使用RDS Default Handler访问数据库,若不通过RDS Handler访问数据库,修改注册表HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DataFactory\ HandlerInfo 将HandlerRequired=1 设置成HandlerRequired =0。请注意,
