System.Data.OleDb.OleDbException未处理:不是有效路径

本文关键字:有效 路径 未处理 Data OleDb OleDbException System | 更新日期: 2023-09-27 18:25:27

这是我第一次尝试从服务器访问数据库文件。如果在本地运行程序,没有问题

我在服务器上存储了ms访问文件,并试图从笔记本电脑上运行该程序,我收到了以下错误。。。。

System.Data.OleDb.OleDbException was unhandled is not a valid path.  Make sure that the path 
name is spelled correctly and that you are connected to the server on which the file resides.

我的连接字符串看起来像这样。。。

myCon = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=H:'name-SERVER'SHAREDFILES'FileRDB.mdb; Jet OLEDB:System Database=system.mdw");

有服务器的用户名和密码。我应该把它包括在连接字符串中吗?

Stacktrace看起来像这样。。。

请有人告诉我如何纠正这个问题。

提前感谢

我不确定我应该为这个线程使用什么标签,但如果我在这里错了,请纠正它。

db是MS Access 2003和visual studio 2010

现在可以工作了。在vista/Windows 7上拥有映射的网络驱动器。右键单击我的电脑>映射网络驱动器>选择驱动器>单击浏览按钮。此时会出现一个菜单,显示为"浏览文件夹--选择共享网络文件夹"。然后选择网络名称和文件夹。完成后单击"确定"。这就是你所要做的。如果有人感兴趣,这里有一些关于如何操作的有用链接。。。
