用ASP打开远端MDB文件的方法
如果你用ODBC connection (DSN or DSN-less)来访问远端的(UNC path)数据库, OLEDB会出现以下错误信息： 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: 'http://www.pstruh.cz Set UM = CreateObject("UserManager.Server") UM.LogonUser "Login with the rights", "Password", "Domain" ... open database ... UM.RevertToSelf
