Microsoft OLE DB Provider for ODBC Drivers
用的是DSN，即用到绝对路径，你没设置过DSN，就会出错。
应用虚拟路径。

<%
' FileName="Connection_odbc_conn_dsn.htm"
' Type="ADO"
' HTTP="false"
' Catalog=""
' Schema=""
MM_re_STRING = "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ="& Server.Mappath("dat/dat.mdb")"
%>
？？？请问这样有什么问题？？？？
<%@LANGUAGE="VBSCRIPT"%>

<%
set Recordset1 = Server.CreateObject("ADODB.Recordset")
Recordset1.ActiveConnection = MM_re_STRING
Recordset1.Source = "SELECT * FROM guest"
Recordset1.CursorType = 0
Recordset1.CursorLocation = 2
Recordset1.LockType = 3
Recordset1.Open()
Recordset1_numRows = 0
%>
上面这样写不行。。。但是我不改Connections里的re.asp文件
就把

<%
set Recordset1 = Server.CreateObject("ADODB.Recordset")
Recordset1.ActiveConnection = MM_re_STRING
Recordset1.Source = "SELECT * FROM guest"
Recordset1.CursorType = 0
Recordset1.CursorLocation = 2
Recordset1.LockType = 3
Recordset1.Open()
Recordset1_numRows = 0
%>
改成-------------
<%@LANGUAGE="VBSCRIPT"%>

<%
set Recordset1 = Server.CreateObject("ADODB.Recordset")
Recordset1.ActiveConnection = "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ="& Server.Mappath("dat/dat.mdb")"
Recordset1.Source = "SELECT * FROM guest"
Recordset1.CursorType = 0
Recordset1.CursorLocation = 2
Recordset1.LockType = 3
Recordset1.Open()
Recordset1_numRows = 0
%>Text
这样结果可以正常运行？
诺我想在改Connections/re.asp文件。应该怎样改？

To sky,
如果你想知道为什么，很简单，输出他们的路径看看，一个对，一个错！
看看我这贴，我其实提过。
