错误类型： Microsoft OLE DB Provider for ODBC Drivers (0x80004005) [Microsoft][ODBC 驱动程序管理器] 未发现数据源名称并且未指定默认驱动程序 /教学管理/学生.asp, 第 14 行

没找到数据库

我在access中已经用odbc制作了数据库驱动，在dm 中使用服务器行为的用户登陆，在调试中出现的此问题，请问如何具体调整？

假如odbc设置dsn位ccc
conn.open "dsn=ccc"
这样就行了

我使用dm 作的，自动生成的代码：
<%
' *** Validate request to log in to this site.
MM_LoginAction = Request.ServerVariables("URL")
If Request.QueryString<>"" Then MM_LoginAction = MM_LoginAction + "?" + Server.HTMLEncode(Request.QueryString)
MM_valUsername=CStr(Request.Form("username"))
If MM_valUsername <> "" Then
  MM_fldUserAuthorization=""
  MM_redirectLoginSuccess="学生家长表.asp"
  MM_redirectLoginFailed="学生处.asp"
  MM_flag="ADODB.Recordset"
  set MM_rsUser = Server.CreateObject(MM_flag)
  MM_rsUser.ActiveConnection = MM_connDSN_STRING
  MM_rsUser.Source = "SELECT stu_name, stu_id"
  If MM_fldUserAuthorization <> "" Then MM_rsUser.Source = MM_rsUser.Source & "," & MM_fldUserAuthorization
  MM_rsUser.Source = MM_rsUser.Source & " FROM stu_infor WHERE stu_name='" & Replace(MM_valUsername,"'","''") &"' AND stu_id='" & Replace(Request.Form("passwd"),"'","''") & "'"
  MM_rsUser.CursorType = 0
  MM_rsUser.CursorLocation = 2
  MM_rsUser.LockType = 3
  MM_rsUser.Open
  If Not MM_rsUser.EOF Or Not MM_rsUser.BOF Then
    ' username and password match - this is a valid user
    Session("MM_Username") = MM_valUsername
    If (MM_fldUserAuthorization <> "") Then
      Session("MM_UserAuthorization") = CStr(MM_rsUser.Fields.Item(MM_fldUserAuthorization).Value)
    Else
      Session("MM_UserAuthorization") = ""
    End If
    if CStr(Request.QueryString("accessdenied")) <> "" And false Then
      MM_redirectLoginSuccess = Request.QueryString("accessdenied")
    End If
    MM_rsUser.Close
    Response.Redirect(MM_redirectLoginSuccess)
  End If
  MM_rsUser.Close
  Response.Redirect(MM_redirectLoginFailed)
End If
%>
如何修改，谢谢指导！

我看不好dm自动生成的代码：

别人来吧~~
