connect vb.net访问数据库.ldb文件 [英] connect vb.net to access databases .ldb file

问题描述

[ ]目标traying连接vb.net访问数据库.ldb文件

目标与访问.mdb文件共存

使用此代码

< pre lang =vb> 公共 con 作为 新 OleDb.OleDbConnection（ Provider = microsoft.jet.oled b.4.0; data source =& Application.StartupPath& \ em.mdb或mde; user id = admin; jet oledb：database密码= 2240）
Dim DataSet1 作为 新 DataSet

这是尝试ldb的代码，这是大问题而且没有show databases

 公共 con 作为 新 OleDb.OleDbConnection（  Provider = microsoft.jet.oled b.4.0; data source =& Application.StartupPath&   \ em.ldb; user id = admin; jet oledb：database password = 2240）

解决方案

亲爱的monemdb，

Quote：

在Microsoft Access 97中，.ldb文件用于确定哪些记录在共享数据库中以及由谁锁定。它在任何用户打开数据库时自动创建，并在最后一个用户关闭数据库时删除。虽然无法直接打开 .ldb文件进行读取，但Microsoft提供了一个动态链接库，它公开了可用于读取.ldb文件的函数。

如果您需要连接到此数据库以枚举已连接的计算机或用户，请参阅： http：/ /support.microsoft.com/kb/186304 [ ^

解决方案

Dear monemdb,

Quote:

In Microsoft Access 97, the .ldb file is used to determine which records are locked in a shared database and by whom. It is created automatically when any user opens a database and deleted when the last user closes the database. While the .ldb file cannot be opened directly for reading, Microsoft provides a dynamic link library that exposes functions that you can use to read the .ldb file.

If you need to connect to this database to enumerate connected computers or users, see this: http://support.microsoft.com/kb/186304[^]
