高工帮忙 上传到服务器后提示出错,我的webconfig是不是设置错了
出错信息如下，好象就是webconfig设置错了，请帮看一下.

Server   Error   in   '/ '   Application.

Runtime   Error  
Description:   An   application   error   occurred   on   the   server.   The   current   custom   error   settings   for   this   application   prevent   the   details   of   the   application   error   from   being   viewed   remotely   (for   security   reasons).   It   could,   however,   be   viewed   by   browsers   running   on   the   local   server   machine.  

Details:   To   enable   the   details   of   this   specific   error   message   to   be   viewable   on   remote   machines,   please   create   a   <customErrors>   tag   within   a   "web.config "   configuration   file   located   in   the   root   directory   of   the   current   web   application.   This   <customErrors>   tag   should   then   have   its   "mode "   attribute   set   to   "Off ".


<!--   Web.Config   Configuration   File   -->

<configuration>
        <system.web>
                <customErrors   mode= "Off "/>
        </system.web>
</configuration>
 

Notes:   The   current   error   page   you   are   seeing   can   be   replaced   by   a   custom   error   page   by   modifying   the   "defaultRedirect "   attribute   of   the   application 's   <customErrors>   configuration   tag   to   point   to   a   custom   error   page   URL.


<!--   Web.Config   Configuration   File   -->

<configuration>
        <system.web>
                <customErrors   mode= "RemoteOnly "   defaultRedirect= "mycustompage.htm "/>
        </system.web>
</configuration>
 



------解决方案--------------------
楼主看看你的定义的 数据库 链接
是否 是在web.config中
并且应该把这个链接 修改为 正确的 配置.

虚拟目录？

呵呵,appSettings是只读的,不能由程序写入. 你只能这样:

<appSettings>
<add key= "dbPath " value= "~/dbTest.mdb "/>
</appSettings>

后台:
string connectionString = System.Configuration.ConfigurationSettings.AppSettings[ "dbPath "]
