记得以前用这种方式更新数据库的时候由于被更新的数据表没有主键会出现这样的错误提示的。----------------------------------------------------------------
欢迎试用ASP.NET大文件上传组件

须要经数据所在的目录添加一个Evrryone用户，并给它写的写的权限就行了，
祝好运~！

如果是XP或windows2003，工具－＞文件夹选项－＞取消简单文件共享
MDB文件－＞右键－＞添加everyone完全权限
上面那位 wggwan(明天会更好) 大哥，源码贴出来了．．．．．不知怎样添加asp.net帐户?
此问题急待解决，请大家帮帮忙！
