ASP是依赖组件的，能访问数据库的组件好多就有好多种,再有就是你微软的东西可是什么都要收钱的啊！
良多时分咱们需求把表格模式的数据转换成EXECL的模式出现在用户眼前，个中有好几个办法可以做到一点，我将引见一种使用ASP完成的办法，该办法答应办事器静态地创立EXECL报表并且不必占用任何办事器空间。该办法还答应多个用户同时收到该数据。然而该办法最少需求EXECL 97的撑持。
空话少说，要完成这个任务最主要的是要告知阅读器HTTP头，就用以下代码：
<%
Response.ContentType = "application/vnd.ms-excel"
%>
上面来看一个例子，假定如今有以下模式的数据：
flavor qty_baked qty_eaten qty_sold price
Boston 24 2 10 0.5
Jelly 24 1 12 0.5
Strawberry 36 1 15 0.5
Chocolate 24 2 6 0.75
Maple 12 1 6 0.75
客户请求用EXECL的模式体现出来，而且但愿个中能加上其他一些盘算汇总
用以下代码：
……
<%
Response.ContentType = "application/vnd.ms-excel"
set conntemp=server.createobject("adodb.connection")
cnpath="DBQ=" & server.mappath("/stevesmith/data/timesheet.mdb")
conntemp.Open "DRIVER={Microsoft Access Driver (*.mdb)}; " & cnpath
set RS=conntemp.execute("select * from donut")
%>
<TABLE BORDER=1>
<TR>
<%
' %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
' % Loop through Fields Names and print out the Field Names
' %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
j = 2 'row counter
For i = 0 to RS.Fields.Count - 1
%>
<TD><B><% = RS(i).Name %></B></TD>
<% Next %>
<TD><B>On Hand (calculated)</B></TD>
<TD><B>Gross (calculated)</B></TD>
</TR>
<%
' %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
' % Loop through rows, displaying each field
' %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Do While Not RS.EOF
%>
<TR>
<% For i = 0 to RS.Fields.Count - 1
%>
<TD VALIGN=TOP><% = RS(i) %></TD>
<% Next %>
<TD>=b<%=j%>-c<%=j%>-d<%=j%></TD>
<TD>=d<%=j%>*e<%=j%></TD>
</TR>
<%
RS.MoveNext
j = j + 1
Loop
' %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
' % Make sure to close the Result Set and the Connection object
' %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
RS.Close
%>
<TR BGCOLOR=RED>
<TD>Totals</TD>
<TD>=SUM(B2:B6)</TD>
<TD>=SUM(C2:C6)</TD>
<TD>=SUM(D2:D6)</TD>
<TD>n/a</TD>
<TD>=SUM(F2:F6)</TD>
<TD>=SUM(G2:G6)</TD>
</TABLE>
……
如许咱们就完成了目标，用户可以在阅读器窗口就翻开它停止复杂操作，也能够保留到硬盘长进行其他操作。我还将引见一种使用filesystemobject操作的办法。请稍候。：） 空话少说，请看代码：
