问题的发生
当我们用 ActiveX Data Objects (ADO) 和Open DataBase Connection(ODBC)试图连接到一个MS Access数据库时,可能会返回如下错误消息:
Microsoft OLE DB Provider for ODBC Drivers error '80004005'
[Microsoft][ODBC Microsoft Access 97 Driver] Couldn't lock file.
发生的原因
以上这条错误消息的产生,是因为你没有对MS Access数据库创建lock file (.ldb)文件的权限。系统默认是,lock file (.ldb)的创建是在一个被看作是Microsoft Access .mdb 文件的同一目录下。
解决方法
按以下步骤进行:
1、准许访问数据库的用户(通常是IUSR_<computername> account)对这个共享文件夹完全支配。
2、由于lock file (.ldb)文件往往是被设置为只读(read-only),所以,在共享往往是被受限制的。那么,我们可以试着使用以下这段示范代码来改变连接方式:
Set Conn = Server.CreateObject("ADODB.Connection")
Conn.Mode = adModeShareDenyWrite '8
' 在 Adovbs.inc中的定义
'---- ConnectModeEnum Values ----
'Const adModeUnknown = 0
'Const adModeRead = 1
'Const adModeWrite = 2
'Const adModeReadWrite = 3
'Const adModeShareDenyRead = 4
'Const adModeShareDenyWrite = 8
'Const adModeShareExclusive = &Hc
'Const adModeShareDenyNone = &H10
