用ASP打开远端MDB

Microsoft OLE DB Provider for ODBC Drivers error ’80004005’

[Microsoft][ODBC Microsoft Access Driver] The Microsoft Jet database engine cannot open the file ’(unknown)’. It is already opened exclusively by another user, or you need permission to view its data.

　　你完全可以避免这种错误--ASP和ActiveX支持两种方式打开MDB文件的DSN-less连接，或由其它机器访问MDB文件。

1. DAO database (only for small load)

Dim File, Conn, RS

Const ReadOnly = False

File = "\\server\share\file.mdb"

Set Conn = CreateObject("DAO.DBEngine.35").Workspaces(0).OpenDatabase(File,,ReadOnly)

Set RS = Conn.OpenRecordset(SQL)

2. ADO + Jet OLE DB provider

Dim Conn, RS

Set Conn = CreateObject("ADODB.Connection")

Conn.Provider = "Microsoft.Jet.OLEDB.4.0"

Conn.Open "\\server\share\file.mdb"

Set RS = Conn.Execute(SQL)

你得确定使用ASP的用户有NT的数据库及共享访问权限。

假定有权限的话，你亦可访问其它机器中的开放数据连接:

Set UM = CreateObject("UserManager.Server")

UM.LogonUser "Login with the rights", "Password", "Domain"

open database
