Web.Config调用了其他目录的数据库。
----------------------------------------------相关代码为：
<appSettings>
<add key= "constr " value= "provider=microsoft.jet.oledb.4.0; data source= "/>
<add key= "connectionstring " value= "server=127.0.0.1;database=call;uid=sa;pwd=123456; "/>
<add key= "blogbd " value= "D:\oblog4\data\oblog4.aspx "/>
</appSettings>
==================================================================
数据库有足够的权限。sql所有者为ODB；OBLOG的数据库EVERYONE可写。
请问如何修正这个错误？？？
===============================================出错信息如下：
Server Error in '/ ' Application.

后台代码！前台的要来干什么。要.cs的。
------解决方案--------------------------------------------------------
是你的后台代码有错
需要你贴出后台代码来
VS中 将工程 设置 asp.net允许调试 设置为true
web.config中
<compilation
defaultLanguage= "c# "
debug= "true "
/>
用dubug模式 执行 程序
看是那一行出的错..
